Purpose The 2018 US Virgin Islands Integrated Water Quality Monitoring and Assessment Report was prepared by the Department of Planning and Natural Resources, Division of Environmental Protection (DPNR-DEP) and is intended to satisfy abbreviated reporting requirements under section 305(b) of the Federal Clean Water Act (CWA). This report is also intended to satisfy the requirements of section 303(d) of the Federal CWA by developing a list of impaired assessment units that will require Total Maximum Daily Loads (TMDLs). This report provides an assessment of the water quality conditions of the Virgin Island’s surface and ground water resources for the period covering fiscal year 2016 and fiscal year 2017 (October 1, 2015 through September 30, 2017). B. Overview of Water Quality Conditions and Trends Water quality in the US Virgin Islands is generally good but declining due to an increase in point and non-point source discharges into the marine environment. Sources such as direct discharges, stormwater run-off and vessel wastes are stressors on US Virgin Islands (VI) waters. 1. Surface Water Non-point source pollution is the major source of surface water contamination in the Virgin Islands. Non-point source pollution sources are diffuse in nature and can be attributed to several causes such as: • Failure to properly install effective silt control devices during construction, • Failure to contain storm water run-off from unpaved roads, • Failure of on-site disposal systems (OSDS), • Resident (native and introduced) and migratory wildlife loading (direct loading and indirect loading, through for example, the grazing on plants that provide ground cover and help control erosion). The discharging of wastes overboard directly into the sea by boat owners and the difficulty in regulating such activity also contributes to non-point source pollution problems seen in the US Virgin Islands. In addition, sewage contributions can be attributed to an antiquated municipal sewage system. Poor preventive maintenance practices due to lack of funding and other resources within the Waste Management Authority result in “bypasses” that result in the release of untreated sewage directly into the waters of the US Virgin Islands. The Government of the US Virgin Islands has made considerable progress towards resolving these issues by the upgrading of new treatment plants and upgrading other portions of the municipal system. 2018 USVI Integrated Report 2. Ground Water • The primary sources of groundwater contamination in the US Virgin Islands are: Bacteriological contamination from failing septic systems • Leaking municipal sewer lines • Migration of contamination from previous injections and disposal practices • Frequent sewage bypasses (generally described as discharges direct to the sea, but with some percolation into sub-soils) Other sources of ground water contamination include intrusion of salt water caused by the over- pumping of the aquifers, invasion of volatile organic compounds (VOC’s), contamination from leaking underground storage tanks, and the indiscriminate/illegal discharges of waste. C. Program Initiatives Under the provisions of the Federal and Local Water Pollution Control Act, the US Virgin Islands Water Pollution Control (WPC) and Water Quality Management (WQM) Programs are mandated to conserve, protect, preserve, and improve the quality of water for public use and the propagation of wildlife, fish and aquatic life for the USVI. To ensure the protection of water quality, projects under WQM monitor compliance with the Water Quality Standards as set forth in the US Virgin Islands Environmental Laws and Regulations. In addition, the program-reporting period (FY2016 and FY2017) saw water quality management activities in the US Virgin Islands being planned for integration for management and reporting purposes with the Unified Watershed Assessment process of the Clean Water Action Plan. This US Virgin Islands Water Quality Assessment presents water quality assessment information in a format that preserves the US Virgin Islands long-term data series by using the same water quality monitoring sites. This report also indicates how these data can be summarized at a level that is compatible for both Water Quality Assessment and Unified Watershed Assessment processes. The report classified these watersheds into 4 different categories, as follows: Category 1 - Watersheds in Need of Restoration These watersheds do not currently meet, or face imminent threat of not meeting, clean water and other natural resource goals. Category 2 - Watersheds Meeting Goals but Needing Preventative Action to Sustain Water Quality. These watersheds meet clean water and other natural resource goals and standards and support healthy aquatic systems. All such watersheds need the continuing implementation of core clean water and natural resource programs to maintain water quality and conserve natural resources. 2018 USVI Integrated Report Category 3 - Watersheds with Pristine/Sensitive Aquatic System Conditions on Lands Administered by Federal, State or Tribal Governments. The USVI Territory works cooperatively with federal land managers to identify watersheds with exceptionally pristine water quality, other sensitive aquatic system conditions, and drinking water sources that are located on lands administered by federal or local governments. These areas include currently designated and potential candidate Wilderness Areas, Outstanding Natural Resource Waters, and Wild and Scenic Rivers. Category 4 - Watersheds with Insufficient Data to Make an Assessment. These watersheds lack significant information, critical data elements, or the data density needed to make a reasonable assessment at this time. The Government of the Virgin Islands is presently enhancing and strengthening its territorial Water Pollution Control Act and revising its Water Quality Standards. The triennial review will be completed when the revised Water Quality Standards are adopted in the later part of FY2018. This ongoing process builds upon previous 305(b) and 303(d) reporting periods. *Note: These categories are distinct from the five (5) Listing Categories [1, 2, 3(a, b, c, d), 4(a, b, c), and 5] applied for the 303(d) list of impaired waterbodies, discussed in Part III-B of this report. D. Summary of Designated Uses Waters of the Virgin Islands are designated for the maintenance and propagation of desirable species of wildlife and aquatic life (including any threatened or endangered species listed pursuant to section 4 of the Federal Endangered Species Act, 16 U.S.C. §§ 1531 – 1544, and/or any threatened, endangered, or indigenous species listed pursuant to Title 12, Chapter 2 of the Virgin Islands Code), primary contact recreation, pursuant to the Virgin Islands Water Quality Standard, Title 12, Chapter 7, §186-1 of the Virgin Islands Rules and Regulations (VIRR). USVI waters are classified into four (4) groups based on designated uses: Class A, B, C and I: Class A waters are marine and coastal waters designated as Outstanding National Resource Waters. These waters have unique characteristics to be preserved (e.g., waters of exceptional recreational, environmental, economic, or ecological significance). Existing conditions for Class A waters cannot be altered except towards natural conditions. Class A water standards are the most stringent of the four (4) classes because of their pristine or near-pristine state. Class A Waters are designated for the maintenance and propagation of desirable species of wildlife and aquatic life (including any threatened or endangered species) and for primary contact recreation. Class B and C are marine and coastal waters designated for maintenance and propagation of desirable species of wildlife and aquatic life (including any threatened or endangered species) and primary contact recreation. Class C waters are those waters which are generally located in industrial harbors and ports and have less stringent water quality standards for certain parameters than Class B waters. 2018 USVI Integrated Report Class I waters are designated aquatic-influenced environments located within land boundaries and can either be inland groundwaters (Subclass IG waters) or inland surface waters. Inland surface waters can be fresh (Subclass IF Waters) or saline or brackish (Subclass IBS Waters). Waters included in Subclass IG includes all groundwaters that are current or potential supplies of potable water (and their associated recharge areas) with a naturally occurring salinity of less than 10,000 mg/L and are designated for use as a potable water source. Inland surface waters (Subclass IF and IBS waters) are designated for the maintenance and propagation of desirable species of wildlife and aquatic life (including any threatened or endangered species), and for primary contact recreation. Detailed specifications for these classes are presented in Part II, Section B, below. E. Highlights of the Rest of this Report • Part III, Table III.C.1 has been updated to reflect the current status of all US Virgin Islands assessment units. • Part III, 2018 Assessment Methodology has been updated. • Part III, C. Monitoring Strategy has been updated. 2018 USVI Integrated Report II. BACKGROUND A. Resource Overview The territory of the United States Virgin Islands (USVI) comprises three major islands: St. Croix, St. John and St. Thomas. Additionally, 57 smaller islands and cays were documented in A Natural History Atlas to the Cays of the US Virgin Islands (Dammann and Nellis, 1992). Taken together, the territory encompasses a total land area of approximately 136 square miles or 110,000 acres (Table II.A.1) characterized by central mountain ranges and relatively small coastal plains. Peak elevations are 1,165 feet on St. Croix (Mount Eagle), 1,550 feet on St. Thomas (Crown Mountain) and 1,297 feet on St. John (Bordeaux Mountain). The islands are generally only 2 to 6 miles wide, with no land location far from the coastal waters. All data in this report focus on the main islands of St. Croix, St. John, and St. Thomas although several enclosed bays within the main islands' watersheds include offshore islands and cays. The return of Water Island to the control of the Government of the US Virgin Islands, after 50-some years of direct federal administration (first as a fort by the Department of the Army during the Second World War, and later as the responsibility of the US Department of the Interior) raises the question of whether this area should be treated as a fourth island. For the purposes of the Water Quality Assessment, Water Island will be treated as another offshore cay or small inhabited island, such as Hassel Island or Great St. James because the area is small (less than 600 acres or 1 square mile), the estimated population is less than 200 permanent residents and the island is practically within St. Thomas Harbor. The offshore cays and small islands are an inherent piece of the natural heritage of the Virgin Islands. Additionally, as an economic asset, these offshore sites could be included within a broad eco-tourism program for the territory. Many government-owned cays have already been established as wildlife reserves pursuant to Title 12 § 94(b)(2) VI Rules and Regulations. A number are important seabird nesting sites, and several are important roosting areas. The surrounding waters of most of the cays and islands teem with marine life, providing food for seabirds and for the fish and shellfish sought by commercial and recreational fishermen. They are also popular dive sites, which are important to the local diving industry. There are no large freshwater lakes or ponds, and no perennial streams on any of the islands; intermittent streams can only be seen after heavy rainfall or during the rainy season (May – November). The absence of large freshwater resources and perennial streams means that guts (watercourses) form the basis for watershed management in the territory. (Relatively small salt ponds are also scattered across the three main islands). This Water Quality Assessment is based on the United States Geological Survey (USGS) 8-digit Hydrologic Units for the US Virgin Islands, which designate two Virgin Islands watersheds: one for St. Croix (21020002), and one for the combined islands of St. Thomas and St. John (21020001). In addition, this Water Quality Assessment also uses 11- and 14-digit Hydrologic Unit definitions, created by the US Geological Service of the US Department of Interior and the Natural Resources Conservation Service of the US Department of Agriculture, to define territorial Watersheds. Within 2018 USVI Integrated Report these fourteen watersheds (seven on St. Croix, four on St. Thomas, and three on St. John), the Virgin Islands have further defined waterbody Assessment Units, which correspond to coastal elements of watersheds. To delineate the Assessment Units (AUs) within the territorial Watersheds, a coastal waterbody delineation was conducted by Battelle (2003). The delineation considered the legal limits of water quality classifications, TMDLs, subwatershed boundaries, shoreline geomorphology, benthic geomorphology, bathymetry and territorial limits, amongst other factors. The waters surrounding St. Croix, St. John and St. Thomas were delineated in to a total of 176 distinct AUs (84 AUs for St. Croix, 33 AUs for St. John and 59 AUs for St. Thomas).

Classifications, Total Waters and Applicable Standards The information on Water Quality Criteria by Classification and pollutant are summarized below in the section Summary of Criterion Levels of Virgin Islands Water Quality Standards and Table II.B.1, which closely follows the wording of Virgin Islands Rules and Regulations. Review of the USVI Water Quality Standards commenced during this reporting cycle but at the time of writing have not yet been promulgated due to the impacts from two Category 5 Hurricanes in September 2017 and later changes in the Territorial Government Administration and a prolonged Federal Government shutdown. The previous standards were promulgated in FY15 August 2015 and remain in effect. As the standards will be promulgated after this reporting cycle, the assessments outlined in this report were made based on the 2015 USVI Water Quality Standards as detailed below. The following serves as the legal description and boundaries for the Territorial Waters: Class “A” Waters Best usage of waters: Preservation of natural phenomena requiring special conditions, such as the Natural Barrier Reef at Buck Island, St. Croix and the Under Water Trail at Trunk Bay, St. John. These are outstanding natural resource waters that cannot be altered except towards natural conditions. No new or increased dischargers shall be permitted. The designated uses of Class A waters are for the maintenance and propagation of desirable species of aquatic life (including any threatened or endangered species) and primary contact recreation. 2018 USVI Integrated Report Quality criteria: Existing natural conditions shall not be changed. The biological condition shall be similar or equivalent to reference condition established for biological integrity within Class A waters. In no case shall Class B water quality standards be exceeded. Legal Limits (1) Within 0.5 miles of the boundaries of Buck Island’s Natural Barrier Reef, St. Croix. Figure 1. Class A - Buck Island, St. Croix 2018 USVI Integrated Report (2) Trunk Bay, St. John. Figure 2. Class A - Trunk Bay, St. John 2018 USVI Integrated Report Class “B” Waters. Best usage of waters: For maintenance and propagation of desirable species of aquatic life (including any threatened or endangered species) and for primary contact recreation. (1) All other waters not classified as Class “A” or Class “C”. Quality criteria: This Class allows minimal changes in structure of the biotic community and minimal changes in ecosystem function.1 Virtually all native taxa are maintained with some changes in biomass and/or abundance; ecosystem functions are fully maintained within the range of natural variability. The biological condition shall be similar or equivalent to reference condition established for biological integrity within Class B waters. Legal Limits (A) Those Class “B” waters not covered by color and turbidity criteria in section 186-3(b)(11) of this chapter include: (i) St. Thomas waters-Mandahl Bay (Marina), Vessup Bay, Water Bay, Benner Bay, and the Mangrove Lagoon. (ii) St. Croix waters-Carlton Beach, Good Hope Beach, Salt River Lagoon (Marina), Salt River Lagoon (Sugar Bay), Estate Anguilla Beach, Buccaneer Beach, Tamarind Reef Lagoon, Green Cay Beach and Enfield Green Beach. (iii) All non-marine waters defined as all Virgin Islands waters shoreward of the mean high-tide line. (B) All other Class “B” waters are covered by the color and turbidity criteria in section 186- 3(b)(11)(B) of this subchapter. 1 See Part III.B.(Assessment Methodology) for details on how DPNR assesses biocriteria to ensure this WQS requirement is upheld, and for future strategies to improve biological assessment. 2018 USVI Integrated Report Figure 3. Class B - St. Croix (only marine waters displayed) 2018 USVI Integrated Report Figure 4. Class B - St. Thomas and St. John (only marine waters displayed) Class “C” Waters Best usage of waters: For maintenance and propagation of desirable species of aquatic life (including any threatened or endangered species) and for primary contact recreation, industrial water supplies, shipping, and navigation. Quality criteria: This Class allows for evident changes in structure of the biotic community and minimal changes in ecosystem function.2 Evident changes in structure due to loss of some rare native taxa; shifts in relative abundance of taxa (community structure) are allowed but sensitive-ubiquitous taxa remain common and abundant; ecosystem functions are fully maintained through redundant attributes of the system. The biological condition shall be similar or equivalent to reference condition established for biological integrity within Class C waters. 2 See Part III.B.(Assessment Methodology) for details on how DPNR assesses biocriteria to ensure this WQS requirement is upheld, and for future strategies to improve biological assessment. 2018 USVI Integrated Report Legal Limits (1) St. Thomas: (A) St. Thomas Harbor beginning at Rupert Rock and extending to Haulover Cut. (B) Crown Bay enclosed by a line from Hassel Island at Haulover Cut to Regis Point at West Gregerie Channel. (C) Krum Bay. Figure 5. Class C - St. Thomas Harbor, Crown Bay and Krum Bay, St. Thomas (2) St. Croix: (A) Christiansted Harbor from Fort Louise Augusta to Golden Rock, along the waterfront and seaward to include the navigational channels and mooring areas. 2018 USVI Integrated Report Figure 6. Class C - Christiansted Harbor, St. Croix 2018 USVI Integrated Report (B) Frederiksted Harbor from La Grange to Fisher Street and seaward to the end of the Frederiksted Pier. Figure 7. Class C - Frederiksted Harbor, St. Croix 2018 USVI Integrated Report (C) Limetree Bay Channel (formerly named Hess Oil Virgin Islands Harbor and HOVENSA Harbor). (D) Krause Lagoon Channel (formerly Martin-Marietta Alumina Harbor and alternatively named Port Alucroix or St. Croix Renaissance Group Harbor). Figure 8. Class C - Limetree Bay Channel and Krause Lagoon Channel, St. Croix 2018 USVI Integrated Report (3) St. John: (A) Enighed Pond Bay Figure 9. Class C - Enlighted Pond, St. John Class “I” Waters Best usage of waters: Class I waters are designated aquatic-influenced environments located within land boundaries and can either be inland groundwaters (Subclass IG waters) or inland surface waters. Inland surface waters can be fresh (Subclass IF Waters) or saline or brackish (Subclass IBS Waters). Inland waters are designated for the maintenance and propagation of desirable species of wildlife and aquatic life (including any threatened or endangered species), as a potable water source, and for primary contact recreation. Legal Limits: Subclass IBS waters include all inland brackish or saline waters and subclass IF waters include all fresh waters. Subclass IG waters include all inland groundwaters that are current or potential supplies of potable water (and their associated recharge areas) with a naturally occurring salinity of less than 10,000 mg/L. 2018 USVI Integrated Report Summary of Criterion Levels of Virgin Islands Water Quality Standards (Abridged): This section is not intended to provide a full overview of the Virgin Islands Water Quality Standards. For further detail, see DPNR (Department of Natural Resources), 2015, Water Quality Standards for Waters of the Virgin Islands: Title 12, Chapter 7, Amendments to Subchapter 186 of Virgin Islands Rules and Regulations. Adopted August 28, 2015. Class A Quality criteria: Existing natural conditions shall not be changed. The biological condition shall be similar or equivalent to reference condition established for biological integrity within Class A waters. In no case shall Class B water quality standards be exceeded (see Table II.B.1 below). In addition, the following quality criteria must be maintained in the area of coral reef systems (as delineated in the Benthic Habitat Atlas of Puerto Rico and the U.S. Virgin Islands (2002)): (a) Temperature: Not to exceed 25-29°C at any time, nor as a result of waste discharge to be greater than 1.0°C above natural. Thermal policies (Section 186-6) shall also apply. (b) Turbidity: For areas where coral reef ecosystems are located, a maximum nephelometric turbidity unit reading of one (1) shall be permissible. Class B & C Class B Quality criteria: This Class allows minimal changes in structure of the biotic community and minimal changes in ecosystem function. Virtually all native taxa are maintained with some changes in biomass and/or abundance; ecosystem functions are fully maintained within the range of natural variability. The biological condition shall be similar or equivalent to reference condition established for biological integrity within Class B waters. Class C Quality criteria: This Class allows for evident changes in structure of the biotic community and minimal changes in ecosystem function. Evident changes in structure due to loss of some rare native taxa; shifts in relative abundance of taxa (community structure) are allowed but sensitive- ubiquitous taxa remain common and abundant; ecosystem functions are fully maintained through redundant attributes of the system. The biological condition shall be similar or equivalent to reference condition established for biological integrity within Class C waters. Numerical criteria for Class B and Class C waters is summarized in Table II.B.1 below. 2018 USVI Integrated Report Table II.B.1 Criterion Class B Class C Dissolved Oxygen Not less than 5.5 mg/l from other than natural conditions Not less than 5.0 mg/l from other than natural conditions pH <8.3 Tolerable Limit >7.0 Normal range of pH must not be extended at any location by more than ±0.1 pH unit. <8.5 Tolerable Limit>6.7 Normal range of pH must not be extended at any location by more than ±0.1 pH unit. Temperature Not to exceed 32° Celsius at any time, nor as a result of waste discharge be greater than 1°C above normal. Areas where coral reef ecosystems are located shall not exceed 25-29°C at any time, nor as a result of waste discharge be greater than 1.0°C above natural. Bacteria The 30-day geometric mean for enterococci shall not exceed 30 CFU/100 mL and no more than 10 percent of the samples collected in the same 30 days shall exceed 110 CFU/100 mL. Same as Class B Phosphorus Total P shall not exceed 50 ug/L any coastal waters Same as Class B Suspended, colloidal or settleable solids None from wastewater sources which will cause disposition or be deleterious for the designated uses shall be present in any waters. Same as Class B Oil and Floating substances No residue attributable to waste water. No visible film; no globules of grease shall be present in any waters. Same as Class B Radioactivity Gross Beta: 1000 picocuries per liter, in the absence of Sr 90 and alpha emitters Radium-226: 3 picocuries per liter Strontium-90: 10 picocuries per liter Same as Class B Taste and Odor None in amounts that will interfere with the use for primary contact recreation, potable water supply or that will render undesirable taste or odor to edible aquatic life Same as Class B 2018 USVI Integrated Report Color and Turbidity • A Secchi disc shall be visible at a minimum depth of one meter • A maximum nephelometric turbidity unit reading of three (3) shall be permissible or a maximum of one (1) shall be permissible in areas with coral reef Same as Class B Toxicity The applicable numeric water quality criteria for toxic pollutants to protect the designated uses of Territorial waters shall be the Environmental Protection Agency's (EPA) national recommended Clean Water Act section 304(a) water quality criteria, EPA's Office of Water, Office of Science and Technology (4304T), (adopted for the protection of freshwater and saltwater aquatic life from acute (criterion maximum concentration) and chronic (criterion continuous concentration) effects; and, the protection of human health from the consumption of organisms). Biocriteria The Territory shall preserve, protect, and restore water resources to their most natural condition. The condition of these waterbodies shall be determined from measures of physical, chemical, and biological characteristics of each waterbody class, according to its designated use. As a component of these measures, the Territory may consider the biological integrity of the benthic communities living within waters. These communities shall be assessed by comparison to reference conditions(s) with similar abiotic and biotic environmental settings that represent the optimal or least disturbed condition for that system. Such reference conditions shall be those observed to support the greatest community diversity and abundance of aquatic life as is expected to be or has been historically found in natural settings essentially undisturbed or minimally disturbed by human impacts, development, or discharges. This condition shall be determined by consistent sampling and reliable measures of selected indicator communities of flora and/or fauna and may be used in conjunction with other measures of water quality. Waters shall be of a sufficient quality to support a resident biological community as defined by metrics based upon reference conditions. These narrative biological criteria shall apply to all marine and coastal waters of the Virgin Islands to include estuarine, mangrove, seagrass, coral reef and other marine ecosystems based upon their respective reference conditions and metrics. General water quality criteria These waters shall be free of substances attributable to municipal, industrial, or other discharges or wastes as follows: (1) Materials that will settle to form objectionable deposits. (2) Floating debris, oils, scum, and other nuisance matter. (3) Substances producing objectionable color, odor, taste, or turbidity. (4) Materials, including radionuclides, in concentrations or combinations which are toxic or which produce undesirable physiological responses in human, fish and other animal life, and plants. 2018 USVI Integrated Report (5) Substances and conditions or combinations thereof in concentrations which produce undesirable aquatic life. (6) Exotic or aquatic nuisance species. All waters of the U.S. Virgin Islands shall meet generally accepted aesthetic qualifications and shall be capable of supporting diversified aquatic life. "Waters" of the U.S. Virgin Islands shall be defined, as follows, as in by Title 12, Chapter 7, Section I82(f) of the Virgin Islands Code; "Waters of the United States Virgin Islands" means all waters within the jurisdiction of the United States Virgin Islands including all harbors, streams, lakes, ponds, impounding reservoirs, marshes, water-courses, water-ways, wells, springs, irrigation systems, drainage systems and all other bodies or accumulations of water, surface and underground, natural or artificial, public or private, situated wholly or partly within or bordering upon the United States Virgin Islands, including the territorial seas, contiguous zones, and oceans." ** Information listed in the table above is from the USVI Water Quality Standards promulgated on August 28, 2015. Class I Subclass of Inland Fresh Waters (IF Waters) and Inland Brackish or Saline Waters (IBS Waters): Quality criteria: Waters in this subclass shall remain in their natural state to the maximum extent possible with an absolute minimum of pollution from any human-caused source. To the extent possible, the ecological character of these areas shall be maintained and protected. The following water quality standards apply to the Class I Waters: (a) Bacteria: The 30-day geometric mean for enterococci shall not exceed 30 CFU/100 mL and no more than 10 percent of the samples collected in the same 30 days shall exceed 110 CFU/100 mL. Subclass of Inland Groundwaters (IG Waters): Quality criteria: Waters in this subclass shall remain in their natural state to the maximum extent possible with an absolute minimum of pollution from any human-caused source. (a) Bacteria: The 30-day geometric mean for enterococci shall not exceed 30 CFU/100 mL and no more than 10 percent of the samples collected in the same 30 days shall exceed 110 CFU/100 mL. Numeric toxic pollutant criteria are also stipulated for Class I waters. Table II.B.2, Figure II.B.2 and Figure II.B.3 provide a summary of the area occupied by each class of marine and coastal waters and their spatial distribution across the three main islands of the USVI. 2018 USVI Integrated Report Table II.B.2 Area of Water Classes by Island St. Croix St. Thomas St. John Total Class A 4.1172 sq. miles --- 0.0685 sq. miles 4.1857 sq. miles Class B 244.89 sq. miles 272.95 sq. miles 79.958 sq. miles 597.8 sq. miles Class C 2.2132 sq. miles 1.0323 sq. miles --- 3.2454 sq. miles Total 251.2204 sq. miles 273.9823 sq. miles 80.0265 sq. miles 605.23 sq. miles Figure II.B.2 Spatial Distribution of St. Croix Coastal Water Classes 2018 USVI Integrated Report Figure II.B.3 Spatial Distribution of St. Thomas/St. John Coastal Water Classes Water Quality Standards to Address Drinking Water Use Attainment The 2015 water quality standards do not address drinking water use attainment. Since most of the USVI’s drinking water supply comes from seawater purified by flash desalinization or reverse osmosis and from traditional rainwater cisterns (still required for all new construction) most national drinking water issues directed at surface or groundwater resources aren’t directly applicable in the Virgin Islands. There are no drinking water source-based quality standards available for organic compounds (volatile, synthetic, herbicides, pesticides and PCB), inorganic compounds, unregulated chemicals, and radiological contaminants that apply to the ocean surrounding the US Virgin Islands because ocean water does not fit the definition of surface water under the Safe Drinking Water Act. Standards do exist under the Virgin Islands Rules and Regulations that demand natural existing conditions for waters designated Class A remain unchanged. All waters of the Virgin Islands should not exceed a geometric mean of 30 enterococci per 100mL or exceed a value of 110 per 100mL more than 10% of the time. The reason that drinking water source-based standards are not yet developed in the US Virgin Islands is that drinking water is generally derived from cisterns holding rainwater at each house or supplemented for public housing and in droughts and other emergencies by desalinization of seawater, as a co-generation by-product of the Virgin Islands Water and Power Authority. The Water and Power Authority in St. Croix maintains some public water supply wells. 2018 USVI Integrated Report Currently, no surface water is used directly for any drinking water supply, although questions have been raised about whether sea water intakes of contaminated water is capable of passing bacterial contamination through the relatively low temperature (60° C) flash desalinization processes. Therefore, the proposed 2019 water quality standards (expected to be promulgated in mid-2019), include a designated use for Class A, B, C and I waters for those being used currently, or that could be used in the future, as potable water sources Determinations as to whether waters can be used as potable water sources will involve assessments, including but not limited to, whether, with available treatment, the water from those sources could meet Federal and Territorial drinking water standards, as well as assessments of the physical and/or chemical characteristics of the water sources, and an understanding that such water sources are declared to be public waters belonging to the people of the United States Virgin Islands, subject to appropriation for beneficial use in the manner set forth in 12 V.I.C. § 151 and not otherwise. Waters in all classes will be expected to aim for and attain that use and therefore enhance public health protection. C. Water Pollution Control Program Under the Water Pollution Control Grant (pursuant to CWA §106), the V.I. Department of Planning and Natural Resources (DPNR), Division of Environmental Protection (DEP) is entrusted with the task of monitoring the marine waters of the USVI and controlling the discharges into those waters. To accomplish this task the Water Pollution Control (WPC) Program is organized into the following sub-programs: • TERRIORIAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMITTING AND COMPLIANCE PROGRAM In FY2009, the WPC Program merged with the Water Quality Management Planning (WQMP) Program. The Water Quality Management Program (WQM) is organized into the following sub- programs (discussed in Section G below): • AMBIENT MONITORING PROGRAM • TMDL DEVELOPMENT AND IMPLEMENTATION PROGRAM • VIRGIN ISLANDS BEACH MONITORING PROGRAM This section will focus on the one WPC sub-program: 1. The Territorial Pollutant Discharge Elimination System (TPDES) Permitting and Compliance Program, which permits and monitors point source pollutant streams discharged into the waters of the VI, in accordance with the VI Water Quality Standards. i. Territorial Pollutant Discharge Elimination System Program The Territorial Pollutant Discharge Elimination System (TPDES) Permitting and Compliance Program is a federally delegated program which permits and regulates the discharge of pollutants from point-sources into waters of the USVI (as defined in 12 V.I.R. & Regs § 184). TPDES Permits are issued in accordance with Title 12, Chapter 7 §184-11 of the Virgin Islands Rules and Regulations, which states that “…no person shall discharge or cause a 2018 USVI Integrated Report discharge of any pollutant without a TPDES permit having been issued to such person…”. TPDES permits require that point source discharges of pollution be monitored by the permittee (facility), and the self-monitoring results are submitted to DPNR-DEP and the United States Environmental Protection Agency (USEPA). The TPDES Program currently regulates discharges from sewage treatment plant outfalls (both public and private facilities), brine discharges from reverse osmosis, desalination (and other technology) freshwater production plants, industrial facility process water discharges, industrial facility storm water discharge, and storm water discharge from construction sites with over one (1) acre of exposed soils. DPNR-DEP conducts compliance inspections and monitoring at all facilities that have been issued TPDES permits on an annual basis to ensure compliance. There are three types of compliance inspections conducted at TPDES permitted facilities throughout the Territory: Compliance Sampling Inspections, Compliance Evaluation Inspections and Pump Station Inspections, which are conducted on a quarterly basis at the Territory’s Publicly Owned Treatment Works (POTW). If a facility is repeatedly found to be in non-compliance with its TPDES permit or has been found to violate the USVI’s Water Quality Standards, enforcement actions may be taken against the facility. The enforcement action usually outlines corrective actions necessary for the facility to return to compliance and, if deemed necessary, fines may also be assessed. Facilities that are enforced against are usually granted the opportunity to work closely with the Department to develop a compliance schedule that the facility will use to achieve compliance. If necessary or when requested, DPNR-DEP may work closely with the USEPA and the Department of Justice (DOJ) to address major enforcement cases. Cases of this nature included an ongoing case against the Department of Public Works which is currently under Federal Consent Decree for unpermitted discharges caused by sewage treatment infrastructure problems throughout the Territory. In such cases, DEP is called upon to monitor the facility in question and produce supporting inspection reports and other pertinent documentation. TPDES Program has several components, all under the auspices of the Division of Environmental Protection: • TPDES Permit Issuance; • TPDES Compliance Inspections: Compliance Evaluation (CEI), Compliance Sampling (CSI) and Pump Station Inspections (PSI); and • Enforcement 2018 USVI Integrated Report TPDES Permit Issuance: Territorial TPDES permits are issued with effluent limitations pertinent to Federal and Local Regulations. The major industrial dischargers, which have permitted discharges of over 1 MGD, include the HOVENSA Oil Refinery, VI Rum Distillery (CVL), St. Croix Renaissance Group, Water and Power Authority in the St. Croix district; the Water and Power Authority in the St. Thomas/St. John district and the Marriott Frenchman’s Reef on St. Thomas. The major municipal dischargers include the St. Croix POTW, Mangrove Lagoon POTW and Charlotte Amalie POTW. The TPDES Program also permits a number of minor industrial and municipal facilities. TPDES Permits are also issued for storm water discharge, both for construction sites that expose one (1) acre or more of soils as well as industrial facilities currently operating within the Territory.

Non-Point Source Program This section of the US Virgin Islands Integrated Water Quality Monitoring and Assessment Report provides an assessment of the water quality conditions based on the implementation of the Non-Point Source Management Program for the period covering fiscal years 2014 and 2015 (October 1, 2013 through September 30, 2015). The Non-Point Source (NPS) Management Program goals for the reporting period remained consistent with that of previous years: to protect ground and coastal waters by mitigating both land and marine nonpoint pollution sources. Non-point source pollution, in the form of polluted runoff, impairs more water bodies than any other source of pollution in the Virgin Islands. Non-point source pollution in the Virgin Islands is caused by rainfall moving over and through the ground. As runoff moves, it picks up and carries away both natural pollutants and pollutants resulting from human activities. These pollutants include sediments, nutrients, pesticides, and toxic substances such as hydrocarbons and heavy metals. Eventually these pollutants are deposited in wetlands, coastal waters and ground water. There are numerous problems associated with non-point source pollution. Two of the major non- point source problems affecting the Virgin Islanders are sedimentation and bacterial contamination . • Sedimentation occurs when soil is eroded from the land surface, such as at construction sites, and deposited onto the land surface or into coastal water bodies. Sedimentation results in problems such as habitat losses and marine life mortality. • Bacterial contamination from sources such as failed septic systems, runoff from animal operations, and sewage discharged from boats can cause serious threats to human health To facilitate discussion, this report for the NPS program is divided into the following two parts: Part I: Program Activity Measures Part II: Program Accomplishments – summarizes the successes of the program • Program Management • Earth Change permitting program • Educational Outreach • Travel and Training • Reporting 2018 USVI Integrated Report PART I: NPS PROGRAM ACTIVITY MEASURES The NPS Program Activity Measures are summarized below: 1.

The Coral Bay Watershed Management Plan was finalized in March 2008 through a collaborative effort of multiple local and Federal agencies, the Coral Bay Community Council (CBCC), and many local land owners and developers -- to serve as a guide for developing 2018 USVI Integrated Report ways to protect Coral Bay from sediment and stormwater pollution. The plan provides a comprehensive set of objectives and actions that address land use planning, protection and restoration of sensitive lands and aquatic buffers, better site design and construction techniques, and effective stormwater management. Please note that the selected example sites are representative; there are many more sites in Coral Bay that deserve equal attention. This plan document is being used now as a helpful outline to undertake detailed actual multi- agency and community discussions to plan activities and prioritize actions on achieving the objectives. The EPA CARE grant being received by CBCC for 2009 and 2010 will bring stormwater expertise to Coral Bay expressly to implement the plan. The plan can be reviewed at http://www.coralbaycommunitycouncil.org/watershed.htm.

Program Management to include development of total maximum daily loads (TMDLs) implementation plans and restoration plans for Virgin Island’s impaired waters; wetlands management, implementation of the Stormwater program; GIS capacity building, etc. 2. Section 319(h) nonpoint source control grants program; performs water quality restoration and educational projects 3. Earth Change permitting program in the second tier of the coastal zone. PROGRAM MANAGEMENT One of the major activities to be undertaken was to attach resources and timelines to the approved 2014-2015 work plan in order to ensure all NPS Tasks and Subtasks were addressed and reported. NPS identified stakeholders such as the St. Croix Environmental Association (SEA), the Environmental Association of St. Thomas (EAST), the Coral Bay Council (CBC), The Nature Conservancy (TNC), and Virgin Islands Conservation Society (VICS) in order to formalize partnerships with local entities. Additionally, governmental agencies/programs such as USDA- NRCS, DPNR-DEP, DPNR-Permits, DEP-Water Quality, DEP-Water Pollution, DPNR-Flood Plain Management, DPNR-CZM, Caribbean Environmental Protection Division CEPD and National Oceanic Atmospheric Administration (NOAA) were also invited for the purpose of integrating NPS goals with other programs by membership in the NPS Pollution Steering Committee. There are currently 25 committee members and we are still recruiting. Meetings were held in the Third and Fourth Quarter to discuss the direction, goals and by-laws development for the new Committee. The reconvened NPS Pollution Committee discussed strategic approaches and adaptive management principals in order to further achieve and maintain water quality standards. The Committee determined that the goal going forward will be the reviewing guidelines and policies in accordance with the approved work plan, and grant agreements, update the Environmental Handbook, and consider developing rules and regulations to give more enforcement authority within guidelines and policies to responsible agencies. Through the Environmental Handbook the NPS Program will update the Management Plan and help to prevent further non-point source pollution, in the form of polluted runoff, which impairs more water bodies than any other source of pollution in the Virgin Islands. Staff was successful in obtaining a conditional approval on a $50,000 VIDPNR Nonpoint Source Implementation Grant to revise the U.S. Virgin Islands Environmental Handbook and Design Manual. A. Total Maximum Daily Load data development and gut characterization The project by TetraTech, Inc. continued in FY14. The objectives are as follows: a). Characterization of land use coefficients for use in determining non-point source pollution loadings for parameters such as Biological Oxygen Demand, nutrients (particularly nitrogen), sediment, bacteria, oil/grease, and impervious surfaces b). Characterization of guts within watersheds feeding a TMDL waterbody in relation to their location, daily flow, and condition (Manning’s roughness coefficient). 2018 USVI Integrated Report The first phase of this project entails a multi-faceted approach to allow for future characterization of non-point pollutant loading coefficients. Several factors that drive pollutant loading regimes were investigated based on available data and literature, and initial recommendations for additional data collection have been developed in anticipation of further dialogue with VIDPNR staff. Factors that drive pollutant loading and were investigated during this phase of work include precipitation distribution information, and in-stream watershed monitoring data. The first section of this memorandum provides our initial assessment of these datasets. The second section of this memorandum discusses out recommendations for future monitoring. Precipitation Estimation and In-Stream Monitoring Data The climate of the Lesser Antilles region is dominated by the easterly trade winds. This maritime tropical region is characterized by fair weather, steady winds, and slight but regular annual, seasonal, and diurnal ranges in temperature. Rain-producing weather systems typically move into the Virgin Islands from the east in summer and from the northwest in winter. These systems tend to produce rain over land when moist, tropical air is forced upward by an island’s higher land elevations. This causes rainfall trends in the Virgin Islands of wet-to-dry patterns from the west end to the east end of the islands. For this reason, the spatial variation in rainfall is large, and precipitation measured at a given station may not accurately represent rainfall even a short distance away. Annual rainfall amounts on St. Croix, for example, differ with respect to physiographic region, and to a lesser extent based on the season. Seasonal rainfall and temperature data collected near Christiansted are shown in Figure 1. The period from September to November is generally when more rainfall occurs, but topographic setting is a more significant variable with respect to rainfall on St. Croix. Figure 1. Monthly temperature and precipitation averages observed at the Bethlehem Upper New Works station near Christiansted, St. Croix. 60 65 70 75 80 85 90 95 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Temperature (F) 0 1 2 3 4 5 6 7 Rainfall (in) Precip.(in) Minimum Temp (deg.F) Maximum Temp (deg.F) Mean Temp (deg.F) 2018 USVI Integrated Report There are four stations in the USVI that monitor at least one meteorological parameter. Two of them monitor precipitation; Bethlehem Upper New Works on St. Croix (Figure 2), and Caneel Bay Plantation on St. John (Figure 3). Surface Airways data (atmospheric pressure, temperature, humidity, cloud cover, wind direction and speed) are collected in Cyril E. King Airport on St. Thomas (Figure 4) and at Christiansted Airport on St. Croix (Figure 2). Figure 2. Meteorological stations in St. Croix, USVI Figure 3. Meteorological stations in St. John, USVI 2018 USVI Integrated Report Figure 4. Meteorological stations in St. Thomas, USVI In an effort to better characterize rainfall patterns in the USVI, VIDPNR has requested that Tt conduct analyses to estimate variable precipitation intensity and time offsets across St. Croix, St. Thomas, and St. John. Significant datasets that were used to derive intensity distribution were obtained from local publications and digital elevation models of the islands. Rainfall Intensity A local assessment of typical annual precipitation patterns was developed by the Department of Conservation and Cultural Affairs (DCCA)/ Fish and Wildlife Service in the 1970s: (http://www.fw.dpnr.gov.vi/education/FactSheets/PDFs/Climatology.pdf). Fact Sheet #2 was obtained from a series devoted to public awareness regarding the USVI, and the fact sheet was digitized into a geographic information system by Tt. This precipitation distribution was incorporated with other GIS layers Tt maintains in-house. This spatial product was then used to derive relative precipitation intensities for each island, based on the location of existing precipitation stations. Intensity multipliers were assigned to each intensity group across the islands (see Figure 5). The ranges provided by the original DCCA data were then translated into relative intensity values. For example, when the Bethlehem Upper New Works precipitation station is overlaid with the digitized rainfall distribution map, its location falls within the 30-35” annual precipitation zone. Using a relative weighting method, all areas on the island of St. Croix were within the 30-35” zone were assumed to experience the same rainfall intensity as the Bethlehem Upper New Works station. For other intensity zones, a multiplier was calculated relative to the 30-35” zone. The multiplier was derived by using the average of each of the precipitation ranges. For example, the value for the 30-35” precipitation zone becomes 32.5” (the nominal precipitation). Because the precipitation station is located in the 30-35” zone (or the 32.5” nominal precipitation), it’s coefficient is 1, which indicates that the precipitation estimate for all areas within that zone should multiply the rainfall observed at the station by 1. 2018 USVI Integrated Report Using the same method as above, the 35-40” zone has a nominal precipitation of 37.5”, and so on for the other zones. Precipitation coefficients were derived for the other zones by dividing the nominal precipitation in that zone by the station’s nominal precipitation. So, to derive the rainfall coefficient for the 35-40” zone, 37.5 was divided by 32.5 to obtain 1.15. Therefore, to estimate rainfall amounts for the 35-40” zone, the observed precipitation from Bethlehem Upper New Works can be multiplied by 1.15. Precipitation coefficients for all areas in the USVI are shown in Figure 5. Once the rainfall intensity was mapped for the USVI, a time offset for rain events was developed. Figure 5. Intensity Multipliers & Meteorological stations in USVI. 2018 USVI Integrated Report Rainfall Time Offsets Due to the intense nature of rainfall events in the Lesser Antilles region, flashy characteristics of the guts that drain the USVI, and implications of discharges to tidal waters, the timing of rainfall events becomes critical in the estimation of fate and transport of pollutants. The morphology of St. Croix, St. Thomas, and St. John effects the distribution of rainfall on these islands, as discussed in the previous section. The mountainous terrain also impedes the movement of squall lines across the island, making travel time nonlinear. Morphology is a significant factor in calculating offsets, as systems must rise over the mountainous sections of the islands before arrival at other locations. As discussed previously, the climate of the Lesser Antilles is relatively stable, with northeasterly tradewinds dominating. Naturally, all squall lines will not have the same characteristics in terms of approach and speed. However, this dominant weather pattern was selected as a model for developing time offsets for the USVI. A northeast wind of 6 km/h was used, as it is the most common wind vector experienced in the USVI throughout the year. Morphology data was obtained in the form of high-resolution, 30-meter interval USGS Digital Elevation Model data for all three islands (see Figure 6). DEM Data for St. Croix, St. Thomas, and St. John were overlaid with a 2km grid oriented in the northeast direction to coincide with the dominant wind vector. The transects spaced 2km apart were used to extract profiles from the DEM dataset, which produced a linear distance and a profile distance (see Figure 7). The linear distance is the straight line distance, whereas the profile distance is the distance traveled over the profile. The profile distance will always be equal to or greater than the linear distance. For each 2km transect interval, the coincident profile distance was plotted. This provided a gridded array of points over the islands that could be contoured and related to a time offset. The profiled distance (see Figure 7) was used to calculate the linear velocity of rain events, assuming the events are moving at 6km/h. For example, an event would cover a linear distance of 6km in one hour. But if the 6km distance is characterized by mountainous terrain, the profile distance would be greater, and it would take a longer period of time to travel the 6km. If the 6km of linear distance is characterized by a profile distance of 8km, then a storm traveling at 6km/h would complete the linear distance in 1 hour and 20 minutes. Figure 8 shows the 2km linear distance grid overlayed with the island boundaries. The datum for St. John and St. Thomas was created to the northeast of St. John at the origin of the prevailing wind. Transects were drawn to the southwest from this datum at 2km intervals. As the transects intersect the land areas (represented by the DEM dataset), the linear and profile distances diverge. For example, Figure 8 identifies one of the transects covering St. John near the midpoint of the island. After traveling 2 grid cells (4km), the profile distance was 4.1km. This represents the elevation change being encountered in the DEM dataset. Likewise, at 6km linear distance, 6.17km has been traveled in profile distance. Points indicating the profile distance were developed to cover the islands prior to contouring. 2018 USVI Integrated Report The point data were then contoured using the Spatial Analyst extension in ArcGIS. Contour lines were generated at 2km intervals, where, assuming a 6km/h wind speed from the northeast, the travel time would be 20 minutes between contour lines. The time offsets were linked to precipitation stations, so that offsets could theoretically be applied to observed data as long as the event has the characteristics that were assumed. The St. Thomas and St. John offsets are in relation to the precipitation station at Cruz Bay, St. John, while the St. Croix offsets are linked to the Bethlehem Upper New Works precipitation station. The time offsets for all three islands are shown in Figure 9. Figure 6. Digital Elevation Model (in meters) developed for St. Croix, St. Thomas, and St. John. 2018 USVI Integrated Report Figure 7.

In-Stream Monitoring Data 2018 USVI Integrated Report Watershed monitoring data was reviewed in an effort to provide an inventory of existing data that could be used to estimate loading rates from watershed sources of pollutants. USGS maintains five watershed stations that provide surface water quality data. All of these stations are located on St. Thomas and have been intermittently monitored between 1967 and 1999. Table 1 identifies that time periods for which data are available for each of the stations, and Table 2 identifies the number of samples and constituents tested for each station. Table 1. Temporal data availability for watershed stations in the USVI. Table 2. Water quality data availability for watershed stations in the USVI. The inventory of water quality data collected by the USGS in USVI watersheds is not extensive and is probably not sufficient for source assessment at the level of detail VIDPNR has requested. The USGS has conducted 18 sampling events for the 5 stations, which is not a sufficient dataset considering the events are spread over 43 years. In addition, only 4 of these sampling events occurred in the last 15 years. It is likely that the characteristics of the areas (e.g land use, land cover) draining to these stations have changed significantly during this time, thus changing the loading rates. However, Tt also investigated the characteristics upstream of the monitoring stations to assess their suitability for future monitoring to derive land use loading coefficients as requested by VIDPNR. Figure 10 shows the land use distribution upstream of the 5 USGS water quality monitoring stations, and the distributions are tabulated in Table 3 for the Turpentine Run system and Table 4 for the unnamed systems. The stations along Turpentine Run include (from upstream to downstream) Hoffman Pond, Turpentine Run at Mt. Zion, and Turpentine Run at Mariendal. The two additional stations are located on unnamed creeks that are separate from each other and from Turpentine Run. Station ID Station Name 50262000 UNNAMED CREEK AT BENNER HILL, ST.

Land use distribution upstream of existing USGS water quality monitoring stations in unnamed systems. The land use data was developed by UVI and is circa 1999. Although it is assumed that distributions have changed since the data were developed, the land use dataset gives a general overview of land use regimes in these St. Thomas watersheds. All five of the USGS monitoring stations are characterized by a variety of upstream land uses. Although a good distribution of land uses helps to account for a variety of pollutant sources, it would be difficult to explicitly characterize them all using ambient water quality sampling alone. Water quality sampling may provide loading estimates for explicit sources if a single source type is located upstream, such as in undeveloped areas. Likewise, other land uses can be characterized if the upstream area is homogenous. This, in addition to sparse water quality data collected at these locations, would add significant uncertainty to land use-specific loading estimates. Monitoring Recommendations A general lack of watershed water quality data exists in the USVI, as discussed previously. In addition, no non-tidal waters are listed as impaired in the USVI. Therefore, background information regarding sources of pollutants is generally lacking, which makes targeting “worst-case” situations difficult. The primary purposes for collecting data and information in the USVI are to gain an understanding of the conditions in the region with respect to land use loading and to apply this information in future TMDL development. The collection of information should include water sample collection for pollutant analysis. Monitoring locations should be selected to reflect impacts from local sources and watershed characteristics, as the TMDL work that will ultimately follow this monitoring effort will need to account for these sources and watershed conditions. Due to the focus on land use sources of pollutants, it is imperative that accurate land use data is incorporated into the analysis. The UVI-ECC land use dataset is circa 1999, and it is assumed that land use distributions have changed since that time.

As such, the involvement of the NPS Pollution Steering Committee, a diverse group of individuals from the public and private sectors is pivotal to ensure that the Territorial NPS Management Program achieves the nine key elements of an effective NPS program as described in the “Nonpoint Source Program and Grants Guidelines for States and Territories”, issued on April 12, 2013 and applies to all Section 319-funded grant activities beginning in Fiscal Year 2014. During fiscal year 2014, the NPS staff reviewed the comments provided by the EPA pertaining to the 2000, Draft Nonpoint Source Management Plan. The staff was assigned various sections of the management plan. The NPS Management plan was revised and the first draft was submitted to EPA for review on December 19, 2014. Execute and Monitor Memorandum of Agreement (MOA) During fiscal year 2015, the NPS Program sponsored two environmental projects with CWA 319(h) funds. Requests for proposal were sent out via Public Service Announcement (PSA) on February 10, 2015. The following proposals were submitted to the U.S.V.I. NPS Pollution Steering Committee: o The Coral Bay Community Council (requested $ 75,055 for their project entitled, “Continued Storm-water BMP Implementation in Coral Bay, St. John, USVI”, o The Smith Bay Association (requested $104,000 for their project entitled, “Smith Bay Water Bay Non-Point Source Pollution Education and Outreach Project”, o The University of the Virgin Islands (requested $ 49,815.64 for their project entitled, “Getting the public involved in Non-Point Source Pollution monitoring in the USVI”. On July 10, 2015, the NPS review team, a subgroup of the U.S.V.I. NPS Steering Committee agreed to fund the Coral Bay Community Council and the Virgin Islands Conservation Society environmental projects. In addition to the environmental projects, the NPS staff was assigned to commence the RFP for Phase II of the 2002 U.S.V.I. Environmental Handbook. Phase II of the handbook consists of revisions to include U.S.V.I. specific design and performance standards, specifications, and trainings for storm- water best management practices to effectively address land-based sources of pollution impacting shorelines and coral reefs. On December 9, 2014, the NPS staff met with representatives of the Virgin Islands Department of Property and Procurement (P&P) in order to gain understanding of their bidding process procedures. Upon receiving clarification, the NPS staff drafted a scope of work and a cover letter for the handbook and submitted these documents to the DPNR Acting Commissioner. Utilize Grant Reporting and Tracking System During fiscal years 2014-2015, the NPS staff entered 30% of the old completed projects from previous years into the tracking system. The following projects were entered into the GRTS system: • Project grant number: 99256106 o NPS Pollution Conservation School Program for Bertha C Boschulte Jr. High School 2018 USVI Integrated Report o Claude O.

The earth change permitting program continues to educate the public by emphasizing the importance of the implementation of non-point source pollution controls, including sediment control, erosion mitigation measures, and correct construction BMPs. In fiscal year 2014, 183 site inspections and 10 enforcement actions were completed on the island of St. Croix. For fiscal year 2015, 180 site inspections and 4 enforcement actions were completed within the territory. Overall, the total number of permits issued within the territory in fiscal years 2014-2015 is 538. Due to an unanticipated resignation of trained Earth Change staff in the St. Thomas/St. John District, and the difficulty in finding qualified candidates, data on Earth Change Permitting activities were impacted. Procedures have since been put in place to continue recording activity in the St. Thomas office until an Environmental Specialist II has been hired. Graph 1.1 compares the number of earth change permits issued within the three districts. 2018 USVI Integrated Report Graph 1.1 The Number of Earth Change Permits Issued in FY 2014-2015 During fiscal year 2014, a total of 526 earth change permits were issued in the Territory. 169 permits were issued on St. Croix, 40 permits were issued on St. Thomas and none on St. John.

Solid Waste Program Under 19 V.I.C. § 1553(g)(1), DPNR is authorized to enforce provisions related to environmental effects of waste disposal, resource recovery and hazardous wastes. Pursuant to 19 V.I.C. § 1560, the Commissioner of DPNR exercised his authority to promulgate rules and regulations for a Used Oil Collection Program under Title 19, Part VI, Chapter 56 of the Virgin Islands Rules and Regulations. Within three years after its inception, the Used Oil Program issued more than 173 permits to facilities territory-wide. These permits were only valid for three years, and subsequently expired. Facilities are, therefore, required to submit updated information regarding their used oil management, and renew the permits to generate, store or transport used oil every three years. The tables below provide a listing of used oil permits by District. All of the permits are listed to reflect the universe of facilities that have been issued permits to date, even if some permits are currently expired. Several businesses have become defunct since the previous reporting period or are no longer generating used oil, and those facilities are no longer included in the database. One of the objectives of the Solid Waste Program’s enforcement strategy is to pursue enforcement against facilities that have failed to renew their permits. Pursuant to 19 V.I.C. § 1561(c), these facilities will be issued a Notice of Noncompliance initially, and enforcement will be escalated if compliance is not achieved within the corrective action period. F. Oil and Hazardous Materials 1. Underground Storage Tank Program As of September 2018, two hundred and eighty-nine (289) underground storage tanks (UST) have been closed in the VI. These closed USTs were assessed, and thirty-seven (37) sites were confirmed to be impacted by oil spills. To date, cleanup was completed at thirty (30) sites. The current backlog is seven (7) leaking underground storage tanks (LUST) sites. Figure II.F.1.a shows the 14-year cleanup trend from FY 2005 through FY 2018 for the USVI. 2018 USVI Integrated Report Figure II.F.1.a. LUST BACKLOG FY 2018 Annually, these numbers will go up or down depending on the discovery of new LUST sites and/or completion of cleanups. For example, in 2018, although cleanup was completed at one site, the backlog did not go down by one (1) from 2017, but instead went up by one (1) as shown in Table II.F.1.a below. Refer to www.epa.gov/ust/ust-performance-measures for detailed information. Table II.F.1.a LUST Clean Up Sites Fiscal Year 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 Cleanups Completed 2 4 0 1 6 0 2 1 5 1 3 0 1 1 Cleanups Backlog 20 16 16 15 11 11 9 9 4 7 5 5 6 7 There are seven (7) active LUST sites. Some of the sites will be on the backlog for many more years as they are in varying stages of groundwater remediation. For example, the groundwater remediation at Green Cay Marina and Esso Farmingdale, will be ongoing for many more years. There are other LUST sites that are not active during FY 2018 because: 2018 USVI Integrated Report • Responsible parties have not initiated site investigation and/or remediation because the owners are unable or unwilling, for example Herbert Grigg Home for the Aged. • Responsible parties are still negotiating the permitting required (for example Gottlieb is required to secure a Coastal Zone Management Development Permit) • Responsible parties are trying to secure funding for the cleanup costs (for example, VIPA Seaplane, C’sted). For these sites, the LUST Trust & Impress Fund can potentially be utilized. DPNR Cost Recovery Policy for Leaking UST Trust & Impress Fund, dated 10/22/15, contained the cost tracking mechanism for using LUST Trust Funds for site investigation. In summary, the Underground Storage Tank (UST) Performance Measures for End-of-Year FY 2018 (data through September 30, 2018) are as follows: i. Corrective Action Measures • No of Active Tanks: 134 • No of Closed Tanks: 289 • No. of Confirmed Releases: action this year: 1; cumulative 37 • No. of Cleanups initiated: 37 • No. of Cleanups Completed: action this year: 1; cumulative 30 • No. of Cleanups Remaining: 7 ii. Compliance Measures • 100 % in Significant Operational Compliance with Release Prevention Regulations • 75 % in Significant Operational Compliance with Release Detection Regulations • 75 % of UST Facilities in SOC w/UST Release Detection and Release Prevention iii. Inspection/Delivery Prohibition • No. of On Site Inspections Conducted: 29 • No. of Delivery Prohibition Actions: 2 2018 USVI Integrated Report As of September 30, 2018, there are 54 active UST systems in the territory, with a total UST capacity of 1,208,000 gallons (Table II.F.1.b). The status of cleanups at LUST sites is provided in Table II.F.1.c.

In the event of a leak, damages and cleanup would be covered. • The status review of twenty LUST (Leaking Underground Storage Tank) sites. • The setup of the UST “Trust and Impress Account” a fund for environmental cleanup. This potentially may impose a gasoline tax of 1 cent/gallon. • The development of soil/groundwater cleanup standards and determine the applicability of Risk-Based Corrective Action levels for UST closures and site assessments. How clean is clean? • Developing a local Certification program for persons working with UST systems. 2018 USVI Integrated Report Pursuant to the Virgin Islands Underground Storage Tank Act (USTA) enacted in May 2000, all new and existing USTs must obtain a permit to use or own/operate at UST system. There are three kinds of permits: To use or own/operate, To Construct/Upgrade, and To Close. All regulated underground storage tanks must be permitted in order to operate. It is unlawful to operate a UST system without a permit. Permit to Use or Own/Operate: An operating permit allows a tank owner to operate an UST system and assures the facility is in compliance with all sections of 40 CFR 280 and 12 V.I.C. Chapter 16. Noncompliance with these laws and regulations is in violation of the permit. The application fee is $500 and the operating permit is good for two (2) years from the date of issue. A completed application MUST include the following: a completed EPA Notification (EPA Form 7530-1), proof of a filed notice of an UST at the recorder of deeds (see appendix A for a template), proof of financial responsibility method, and copy of last twelve (12) months of leak detection results Permit to Construct/Upgrade: A permit to construct or upgrade is necessary for any type of new UST construction or an upgrade to a current UST system. The application fee is $500 and the permit to construct/upgrade is good for one (1) year. Plans and specifications must bear the seal or number of a professional engineer registered in the United States Virgin Islands. Any installation, design, retrofit, repair, maintenance, or conduct of tank testing or analysis must be conducted by certified individual. Permit to Close: A permit to close is necessary for the closure of a regulated UST system. Cleanup costs for petroleum releases can be very expensive, even small releases over a period of time can contribute to large cost cleanups. Therefore, UST owners/operators are required to have the means to pay for the costs of corrective action and compensating third-parties for bodily injury and property damage due to a leaking UST. It is important that financial responsibility is met in the event of a leak so corrective action can begin promptly, potentially keeping cleanup costs relatively low. The financial responsibility regulations allow UST owners and operators to choose from a variety of financial mechanisms to comply with the regulations. One of these financial mechanisms is the use of insurance; owner and operators can call the National Association of Insurance Commissioners at (816) 842-3600 or http://www.naic.org/state_web_map.htm for information. 2. Terminal Facility License Program At present, there are approximately 78 facilities that are regulated by the Terminal Facility License (TFL) Program of DEP. Some of these facilities may not be considered waterfront, as defined by the Oil Spill Prevention and Pollution Control Act, 12 VIC §707 et. seq. The number of TFL is on the increase as more facilities are going off WAPA grid. It has been DPNR’s practice and policy to regulate all above ground storage tanks (AST) that stores greater than 1,200 gallons of oil as a TFL; regardless of location. 2018 USVI Integrated Report There are also several Underground Storage Tank (UST) System retail gas stations (non-waterfront) that utilize ASTs for the storage of diesel fuel. They are NOT regulated by TFL program, despite the following: a. the AST storage capacity is greater than 1,200 gallons; b. the stored material is diesel, which falls within the definition of “oil”; c. the need for the Spill Prevention Control and Countermeasures (SPCC) Plan due to inadequate secondary containment, poor maintenance, poor housekeeping, lack of spill kits, etc.; PERMITTING Permitted facilities There are 78 facilities that have been assigned with a TFL Permit Number. These facilities and their permitting status are listed in Table II.F.2.a. The breakdown by island is as follows: St. Thomas: 37 (47%) St. John: 7 (9%) St. Croix: 34 (44%) TABLE II.F.2.a: List of Terminal Facilities Facility Name Physical Address Permit Number Limetree Bay Terminals LLC (FKA Hovensa) #1 Est Hope St. Croix VI 00820-5625 STX-001 PUMA Terminal STX Henry E.

The Used Oil Program The Solid Waste Program is charged with regulating commercial facilities that generate; store and transport used oil within the Territory. Used Oil is a solid waste that has been designated as a “Special Waste” because of its properties or the particular nature of the waste that can create solid waste management problems. Such problems may result from the illegal dumping or accidents that contaminated the environment and endanger human health. To help protect the valuable resources of the Virgin Islands, the solid waste program aggressively conducts inspections and issue permits to facilities that generate and store used oil. Such initiative helps to protect the area of land where all of the water that is under it or drains off of it goes into the same place called a watershed. The figures and tables below provide a listing of used oil permits issued within each district in the Virgin Islands. All of the permits that are listed reflect the universe of facilities that have been issued permits to date. One of the objectives of the Solid Waste Program’s enforcement strategy is to pursue enforcement against facilities that have failed to renew their permits. Pursuant to 19 V.I.C. § 1561(c) (2013), these facilities will be issued a Notice of Noncompliance initially, and enforcement will be escalated if compliance is not achieved within the corrective action period. Figure II.F.3.a graph represents the distribution of 133 used oil facilities in their perspective watershed across the island of St.Croix. 130 of those facilities were issued permits for the generation and storage of used oil. The majority of facilities, a total of 38 or 28% are located in the Hovensa watershed.

Hazardous Waste Program The Virgin Islands implements its own hazardous waste program independent of the US Environmental Protection Agency. All facilities which generate, store, transport and/ or collect hazardous waste must meet the Territory’s requirements except where federal requirements are more stringent or broader in scope. The Virgin Islands has not adopted the Universal Waste Rule. As such, no waste may be managed as universal waste. Rather, all hazardous waste in the Virgin Islands must be managed under traditional hazardous waste requirements based on total monthly waste. Any person engaged in the generation, storage, transportation, treatment, disposal or recovery of hazardous waste shall obtain a permit thereof from the Department of Planning and Natural Resources. Permits must be renewed annually.

Brownfields Program A brownfield is a property of which the expansion, redevelopment, or reuse may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. It is estimated that there are more than 450,000 brownfields in the United States. Cleaning up and reinvesting in brownfield properties increases local tax bases, facilitates job growth, utilizes existing infrastructure, takes development pressures off of undeveloped, open land, and both improves and protects the environment. In 2009 DPNR conducted nine Phase I Environmental Site Assessments for properties located throughout the Territory. The purpose of these environmental assessments was to describe current site conditions and to establish if there was evidence that a release of oil or hazardous materials had occurred at the site or that a threat of release exists. Such a release could represent a liability to the property owner or operator. 2018 USVI Integrated Report Table II.F.5.a List of Brownfields Sites in USVI Facility Name Location Recommendation 15 & 16 Prince Street & 54 & 55-B Hospital Street Frederiksted, St. Croix No further oil and/or hazardous materials assessments activities are necessary at this time 6, 6-a & 8 Penitentiary Land Christiansted, St, Croix Further assessment activities are necessary at the site.

Wetlands Programs 1. BACKGROUND The quality of life in the Virgin Islands and the strength of the Virgin Islands economy depend heavily on maintaining and restoring the health of the nearshore coastal environment; including wetlands, mangroves, coral reefs, and seagrass beds; communities that form a tightly linked ecosystem connected through hydrology and runoff. For the past several decades, population growth has compounded the effects of poor land use practices. This is manifested in catastrophic runoff, sedimentation, nutrient enrichment from failed septic systems and pollutant contamination of coastal wetlands, waters, and bays. Various studies have associated land use in upland areas of watersheds are adversely affecting low-lying terrestrial and marine resources. Nevertheless, the extent of the impacts across the Territory is unknown, and a comprehensive assessment of the watersheds and wetlands of the VI is not presently complete. Additionally, the existing datasets maintained by public institutions have not been made available in published documents or placed into a web-accessible database for resource managers and public use. DPNR has standards applicable to wetlands in the USVI Water Quality Standards [VIRR §186-4(a)]. PHASE I The first phase of the wetlands inventory project, titled, “The Virgin Islands Wetlands and Riparian Areas Inventory: A Pilot Study to Characterize Watersheds and Wetland Systems, Phase I”, was completed in 2004 by the Department of Planning and Natural Resources, in partnership with Island Resources Foundation (IRF) and the University of the Virgin Islands (UVI). Phase I of the project focused on a limited assessment of watershed/wetland ecosystems. Geographic Information System (GIS) technology was used to produce an inventory of watersheds and wetlands (type and location) throughout the U.S. Virgin Islands (USVI), produce GIS map products, and data for statistical and spatial analyses. Eighteen (18) priority watersheds (of the 50 in the USVI) were assessed and characterized using a matrix based on categorizing watersheds into three groups; (i) undisturbed, (ii) moderately disturbed, and (iii) highly disturbed watersheds. Vegetation characterization, water chemistry sampling, sedimentation history, and an Index of Biological Integrity assessment were completed within each selected watershed. The information and data gathered from the pilot study of Phase I were used by the project collaborating institutions to determine the proposed Scope of Work for Phase II of the project. PHASE II The “Virgin Islands Wetlands and Watersheds Characterization Phase II: Inventory, Monitoring, Assessment, Management, and Education in the U.S. Virgin Islands”, began in 2007 and was designed initially to complete the watershed/wetlands assessment for the Virgin Islands by compiling existing data from multiple projects and sources, filling data gaps, developing appropriate management strategies, and educating the public about the importance of wetlands and watersheds. Phase II was completed in late 2010. The following major outputs of Phase II were delivered to DPNR via CDs and DVDs: 1. Framework for the Management of Wetlands in the US Virgin Islands; 2. WETLANDS Book; 3. WETLANDS Book (Web Version); 2018 USVI Integrated Report 4. GIS Layers (Folder); 5. MAP_CRX; 6. Map_JOHN; 7. Map_TOM; 8. QUALITY ASSURANCE PROJECT PLAN; and 9. Final Technical Report. 2. TYPES OF WETLANDS Wetlands provide a range of resources and services that contribute to the economic and social development of the USVI. However, various development activities result in significant degradation of the very resources that support the development of the USVI. In an effort to improve the overall development process to minimize the negative anthropogenic effects, policies, laws, and initiatives have been developed to protect our natural resources. The primary purpose of these associated laws and programs is to ensure that development can be sustained, and the quality of life can be maintained for current and future generations of Virgin Islanders while at the same time protecting these natural resources. As defined by 12 VIRR §184 de (2007), “Wetlands means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.” Each type of wetland is formed under a specific set of conditions and will typically have associated plants (flora) and animals (fauna). Type 1: Watercourses A watercourse is defined in the Virgin Islands Code as “… any stream with a reasonable well-defined channel, and includes streams which have a permanent flow, as well as those which result from the accumulation of water after rainfall and which regularly flow through channels formed by the force of the waters.” See 12 V.I.C. § 123(b). In the USVI, watercourses are commonly referred to as ghuts/guts. These ghuts are the main drainage channels for discharge of runoff from rainfall events. In addition to that function, ghuts provide a range of services that support the development processes of the USVI. Ghuts also contain permanent pools of freshwater, which function as habitats for rare species of aquatic animals (e.g. Mountain Mullet and American Eel). Ghuts take a range of shapes, sizes, and depths, depending on the terrain and the size of the watershed. The vegetation found inside ghuts also varies accordingly, but two distinct forest types have been associated with ghuts. These forest types are Gallery Moist Forest and Gallery Shrubland. Ghuts of Interest are those that meet any one of the following criteria: ➢ Ghuts with permanent pools ➢ Ghuts currently used for recreational purposes ➢ Ghuts supporting other community uses 2018 USVI Integrated Report ➢ Ghuts containing critical habitats ➢ Ghuts supporting endangered species of plants or animals ➢ Ghuts containing significant historic, archeological, or cultural resources ➢ Ghuts facing significant threats – e.g. dumping from construction activities or used for sewage disposal.

Marshes in the USVI are typically fresh-water wetlands formed in depressions in the landscape and maintained by surface or subsurface flow of water. Type 3: Swamps A swamp is defined as “an area intermittently or permanently covered with water and having trees and shrubs” (http://water.usgs.gov/water-basics_glossary.html). In the USVI, swamps are generally located on the coast. Water level is determined mainly by surface runoff during the rainy season, but brackish conditions exist in areas of the swamp closest to the sea, or during the dry season. As a result 2018 USVI Integrated Report of this salinity gradient, plants adapted to both fresh water and saline conditions may be found in some swamps (e.g. Magen’s Bay swamp in St. Thomas). Type 4: Artificial Ponds and Impoundments “A pond is a body of standing water, either natural or man-made, that is usually smaller than a lake” (http://en.wikipedia.org/wiki/Pond). In the USVI, man-made (artificial) ponds are created primarily for provision of water for agricultural purposes. Increasingly, ponds are created for storm-water management purposes on sites with large developments or on sites that are periodically flooded. An impoundment is a body of water resulting from the placement of a stone dyke or earthen berm across a natural drainage channel (ghut). Impoundments were used in the early 1900s as part of the system of collection and distribution of potable water, particularly on St. Croix. Currently, impoundments are constructed and used mainly to provide water for agricultural purposes. Both ponds and impoundments provide habitats for a range of resident and migratory species of water birds. Type 5: Salt Ponds A salt pond is a coastal wetland that is separated from the sea by a low sandbank, sand dune, or similar feature. Salt ponds are formed over long periods by the accretion of reefs, growth of mangroves, or the accretion of sand along the mouth of an embayment. Once the pond is separated from the sea, water exchange between the two is primarily through the separating barrier. Depending on the size and structure of the salt pond, openings to the sea may be created during the rainy season if the pond collects significant amounts of surface runoff. The barrier may also be overtopped by the sea during periods of significant wave action. Such wetlands are commonly called salt ponds because the water in the ponds becomes hypersaline during the periods when the water level is low; that is, the water becomes more saline than ordinary sea water. In some ponds, the salt can be seen as a crystalline deposit along the edges of the pond or towards the landward portion (back) of the pond. Salt ponds provide a habitat for many species of birds, but few plants are adapted to survive in such hypersaline conditions. Plants typically found at salt ponds are Black Mangrove, White Mangrove, and the shrubs Saltwort and Sea Purslane. Type 6 Lagoons A lagoon is defined as “a stretch of salt water separated from the sea by a low sandbank, coral reef or similar natural or manmade feature.” In the USVI, lagoons are typically formed by one of two processes. One process involves wave action moving sand and gravel along the shoreline, periodically closing the mouth of an embayment. Sandbars are sometimes breached by strong wave action, particularly during storms. Sandbars/sandbanks often become colonized and stabilized by plants, which can result in the closure becoming semi-permanent or permanent over time. The second process involves the formation of a sandbar across the mouth of a seasonal stream (ghut). In such cases, the sandbar is periodically breached by wave action or by surface runoff discharged through the ghut after rainfall events. Lagoons can have very restricted access or narrow channels that permit fairly consistent flows between the lagoon and the sea. Lagoons are ecologically productive sites, providing habitats for a range of fish and bird species, including migratory species of birds. Examples of lagoons are the Altona Lagoon (St. Croix) and Benner Bay/Mangrove Lagoon (St. Thomas). 2018 USVI Integrated Report Type 7: Seagrass beds Seagrass beds are ecosystems dominated by marine grasses. Seagrass beds typically inhabit shallow nearshore areas but can be found in a range of depths from shallow lagoons to open coastal areas 60 feet in depth. There are 40-50 species of seagrasses world-wide, and most are found in the tropics. Though seagrass beds are dominated by seagrasses, the communities contain many species of algae. Seagrass beds function as important nursery areas for a wide variety of marine organisms (including important food species). Seagrass beds also function to colonize open areas, and their root systems help to stabilize unconsolidated soils. 3. PRIORITIES FOR MANAGEMENT OF WETLANDS The major issues and priorities currently relevant to wetlands are: 1. Integration of the Policy Framework There are several laws relevant to the management of wetlands, and those laws are administered by several agencies. The programs managed by the various agencies are usually in line with national priorities. In 2010, the Department of Planning and Natural Resources initiated activities to develop a Wetlands Management Program. That program was to establish a mechanism for integration of the wetlands-related policies and programs of the public agencies in the U.S. Virgin Islands, including the involvement of community organizations. However, since that time the program integration has stalled. 2. Reduction of Threats There are significant threats to wetlands and associated resources from natural and man-made sources. The man-made threats are primarily from land use activities (e.g. changed drainage, sediment from construction activities, filling of wetlands, disposal of solid waste and effluents), but also from illegal practices (e.g. solid waste disposal). These threats reduce the benefits provided by wetlands. While threat reduction is a priority of the management agencies, the most important require changes in attitudes and practices of individuals in the community. 3. Storm Water Management Due to the topography of the islands, most development activities (including residential development) involve the channeling of surface runoff from rainfall events. Poor storm-water management practices result in damage to wetlands, social infrastructure (e.g. roads), and private property. Individuals and companies undertaking developments must therefore use best practices in the design of stormwater management systems. 4. Future Demand for Goods and Services from Wetlands The existing uses of wetlands are expected to continue. There is increased use for recreation, including eco-tourism ventures. With increased development activity, particularly larger resort projects, there is increased use of wetlands for storm-water management. It is forecasted that global warming will increase rainfall variability and intensity. As such, wetlands will play an even greater role in flood protection. 2018 USVI Integrated Report 5. Information Management In order to make informed decisions concerning the management of wetland resources, the regulatory agencies are constantly updating the databases on physical conditions and status of the resources. The community should become engaged in the management process, especially by sharing information on the use of wetlands and associated resources, and threats to such resources. The 2019 revision to the USVI Water Quality Standards has additional language that is more protective of wetlands. 4. FRAMEWORK FOR MANAGEMENT OF WETLANDS IN THE USVI Rationale for Development of a Wetlands Management Framework Due to the range of benefits provided by wetlands, as well as their distribution across the topographic landscape, wetlands fall within the area of responsibility of several Territorial and U.S. Federal agencies. As such, wetlands form critical components of several programs designed to maintain the economic growth of the USVI and quality of life of its residents. Environmental and development programs in which wetlands play a critical role include: (a) Agriculture Development – Impoundments were established to collect water for agricultural uses. The 1979 report on the USVI Sediment Reduction Program noted that there were 278 impoundments in the USVI in 1979 (BC&E/CH2M Hill, 1979). (b) Reduction in Non-Point Source Pollution – The 1979 Sediment Reduction Program was designed around the functioning of impoundments as sediment traps. The existing Earth Change Permit process was similarly designed to reduce soil erosion and sedimentation of waterways, and development activities affecting ghuts are regulated within this process. (c) Coastal Zone Management – Wetlands form one of the nine (9) Enhancement Areas for the USVI Coastal Zone Management Program, as required by Section 309 of the Coastal Zone Management Act, 1972. (d) Wildlife Management – Wetlands function as important habitats for a range of wildlife species, and associated management interventions range from periodic resource assessments to designation and management of wildlife reserves by both Territorial and Federal agencies. (e) Water Resources Management – Surface water forms one of the components of waters of the USVI as defined by 12 V.I.C. § 182(f). While there is no water resource management program, the non-point source pollution program was developed to protect the quality of the waters of the USVI for a range of social and ecological purposes. (f) Flood Control – Storm-water management in development activities and general flood control are managed by two separate agencies of the Government of the USVI (Department of Public Works and Department of Planning and Natural Resources). (g) Waste Management – Wetlands are used as part of the waste disposal strategy in the USVI, in that; a number of municipal sewage treatment plants discharge effluent directly to ghuts. Discharge of 2018 USVI Integrated Report untreated sewage to wetlands also takes place when there is equipment failure. Additionally, the two municipal landfills are located in wetlands. Despite the above-mentioned program imperatives that involve wetlands, there is no wetlands program in the USVI. Attempts to establish a wetlands program include the 2006 draft wetlands conservation plan prepared by the Division of Fish and Wildlife and the current attempt by the Division of Environmental Protection. However, a wetlands program designed for a single agency to fulfill its mission objectives will not accommodate the aforementioned range of program needs. This is particularly true as a number of the uses of wetlands are conflicting across the various programs. What is needed is a unified approach that supports multiple policies and program objectives, and that prevents program conflicts. This unified approach to wetlands management is hereby termed the “Wetlands Management Framework for the U.S. Virgin Islands”. The purpose of the Wetlands Management Framework is to ensure that all management interventions for wetlands in the U.S. Virgin Islands are designed based on a single policy and strategy and that institutional arrangements are established to minimize waste and conflicts while maximizing the impacts of each management intervention. Current Wetlands Management Framework There is a variety of laws that provide the foundation for a wetland management framework, and there are both Federal and Territorial agencies that are involved in programs and initiatives affecting wetlands. Though there is this range of institutions and programming that affect wetlands in one way or another, the focus on wetlands appears to be tangential at best. Programs and resource management strategies that should have wetlands management as a central feature have either been inexplicably terminated (Sediment Reduction Program), inconsistent in application (Areas of Particular Concern), relegated wetlands to a low level of priority (Coastal Zone Management 309 Program) or treat wetlands as tangential (Water Pollution Control Program and 2005 Comprehensive Wildlife Conservation Strategy for the USVI). Wetlands are mentioned in the priority goals and objectives identified in the 2018 USVI Coral Reef Management Program, so some focus from the DPNR Division of CZM is increasing. Two of the four priority sites (St. Thomas East End Reserve and St. Croix East End Marine Park) include large areas of wetlands, and CZM, including its St. Croix East End Marine Park (EEMP) Program, has been including these wetland areas more and more in watershed management plans. However, the absence of policies and guidelines for wetlands management inhibit the development or integration of relevant programs. Even with policies to increase protections for wetlands approved by the Coastal Zone Management Commission in 2006, rules and regulations need to be promulgated and adopted within the coastal zone management program. Further, the single attempt to develop a wetlands conservation plan (Platenberg, 2006) focused on one district, and has not been approved or implemented. Lastly, there is no institutional arrangement that supports information sharing and collaborative programming, both necessary to ensure the development of synergies between the various programs. 2018 USVI Integrated Report 5. TRENDS AND MAJOR ISSUES CURRENTLY RELEVANT TO WETLANDS According to the 2018 US Virgin Islands Coastal Zone Management Program, Section 309 Assessment and Strategy, the overall trend is that there is little or no change. This lack of change appears to reflect observations in the field. The US Virgin Islands has seen a significant economic downturn since 2002 and there has been minimal land development during that time. The majority of the development has been small scale residential, rather than larger commercial developments. Land- cover change analysis for St. Croix (excluding St. Thomas and St. John) indicates a trend of decreasing cultivated areas that either revert to forest or are developed into small scale residential development. The trends that have been identified are: (a) Reduction in Acreage of Wetlands in the U.S. Virgin Islands – Damage to wetlands and loss of acreage has been chronicled in several reports (Sladen 1986, Stengel 1998). The major activity contributing to loss of wetlands is (past and current) development activity, primarily industrial, resort, and marina development. The continued generation of a range of other threats to wetlands and associated resources (Gardner et al, 2008) remain a cause of concern. While as noted above in the first paragraph of this section, the overall trend is that there is no change, consistent sediment buildup, particularly from the effects of the 2017 Hurricanes Irma and Maria hitting the Territory, has caused a general trend to reduce the overall acreage as well as shrinking the depth of useable acreage for flora and fauna. (b) Continued Provision of Resources and Services – Wetlands continue to provide a range of resources and services (Virgin Islands Department of Agriculture 1973, Smith 1989, Kelsey et al 2005, Rennis et al 2006, Gardner et al 2008, Valiulis 2009). In addition to the provision of water and food, the environmental services provided by wetlands include wildlife habitats, water purification, groundwater recharge, flood reduction, and storm protection. This trend continues into 2018, however, with sediment buildup as noted above, potential for reduced useable space can cause reduced resources and services, making it difficult for wetlands to flourish without implementation of future management practices. (c) Contribution to Economic Development – Wetlands have played a significant role in the economic development of the U.S. Virgin Islands (Gardner et al, 2008) through the provision of water for domestic, agricultural, and industrial purposes. Current direct contributions include provision of recreational opportunities, educational opportunities, and water for agriculture. The major issues and priorities are: (a) Need for an Integrated Policy Framework – There are several sets of VI laws and Code relevant to the management of wetlands and are administered by different agencies. Though the programs managed by the various agencies are usually in line with national priorities, there is a need to establish a mechanism for integration of the local wetlands-related policies and programs of the 2018 USVI Integrated Report public agencies in the U.S. Virgin Islands, including the involvement of non-governmental organizations. (b) Existence of Significant Threats – There are significant threats to wetlands and associated resources from natural and man-made sources. The man-made threats are primarily from land use activities (e.g. changed drainage, sediment from construction activities, filling of wetlands, disposal of solid waste and effluents), but also from illegal practices (e.g. solid waste disposal). These threats reduce the benefits provided by wetlands. While threat reduction is a priority of the management agencies, success of management interventions requires changes in attitudes and practices of individuals and institutions in the community. (c) Need for Improved Storm Water Management – Due to the topography of the islands, most development activities (including residential development) involves the channeling of surface runoff from rainfall events. Poor storm-water management practices result in damage to wetlands, social infrastructure (e.g. roads), and private property. Individuals and companies undertaking developments must therefore use best practices in the design of storm-water management systems. (d) Future Demand for Resources and Services from Wetlands – The existing uses of wetlands are expected to continue. There is increased use for recreation, including ecotourism ventures. With increased development activity, particularly larger resort projects, there is increased use of wetlands for storm-water management. It is forecasted that climate change will increase rainfall variability and intensity. As such, wetlands will play an even greater role in flood protection. (e) Need for Improved Information Management – There is no structured program for research and monitoring of wetland resources. As such, data collection is sporadic, ad hoc, and not necessarily linked to institutional mandates or programs. Data and information are consistently lost. Additionally, databases compiled by Federal agencies are not utilized by USVI regulatory agencies for management decision making. In order to improve decision making in the development planning and development control processes, the environmental management agencies need to develop an overall data management strategy. That strategy should ensure compatibility of data collection regimes and data management systems, as well as establishment of data sharing mechanisms. The civil society institutions engaged in wetland initiatives should also be brought into the information management process. Other issues requiring attention are: (a) Community Perception of the Value of Wetlands – The continuing threats to wetlands and associated resources indicate that there is a general perception in the USVI that wetlands are not important. However, the conflicts that sometimes arise during public hearings for development projects often focus on environmental issues, including potential impact on wetlands. This contradiction suggests that there is no consensus in the community regarding the value of wetlands. This issue should be addressed in order to reduce conflicts within the development control process and enable the regulatory agencies and community to make informed decisions regarding tradeoffs in the development process. 2018 USVI Integrated Report (b) Climate Change – Climate change scenarios for the Caribbean suggest that sea level rise will be approximately 1.5 feet over the next century. This will result in inundation of some coastal areas, increasing acreage under wetlands, but also impacting negatively on social infrastructure and some major resources (e.g. aquifers). More immediately, increased intensity of storms and changing rainfall patterns are expected to create significant impacts on ecosystems, including wetlands. A comprehensive monitoring program should be established to support informed resource management decision making, particularly for critical or fragile ecosystems. 6. PROPOSED WETLANDS MANAGEMENT FRAMEWORK The Wetlands Wise Use Project of the Convention on Wetlands of International Importance especially as Waterfowl Habitat (Ramsar Convention) identifies the elements of an effective wetlands management program as: • Appropriate Policy Framework; • Appropriate Legal Framework; • Appropriate Institutional Framework; • Management Strategy; • Management Plan/Action Plan; and • Institutional Program/Annual Plan. Appropriate Policy Framework The development of an appropriate policy framework is best guided by an environmental ethic, which provides the broad philosophical basis and guiding principles for policy and program development. The guidelines prepared by the Ramsar Secretariat on the wise use of wetlands (Davis, 1993) identify the following as principal elements of a national wetland policy: A. Improvement of institutional arrangements so that wetland policies can be fully integrated into the planning process; and the establishment of mechanisms and procedures for incorporating this integrated, multi-disciplinary approach into planning and execution of projects concerning wetlands. B. Review of existing legislation and government policies (including subsidies and incentives) including, where appropriate, application of existing legislation and policies, adoption of new ones, and use of development funds for wetlands. C. Increasing knowledge and awareness of wetlands and their values, including exchange of information, propagation of their benefits and values (a statement of which is given), review of traditional techniques, and training of appropriate staff. 2018 USVI Integrated Report D. Review of the status of wetlands in the national context, including compilation of a national inventory, and definition of each wetland's particular values and conservation priorities. E. Addressing of problems at particular wetland sites, by integrating environmental considerations into their management, regulated utilization, establishment of management plans, designation as appropriate for the Ramsar List, establishment of nature reserves and, if necessary, restoration. Appropriate Legal Framework The legal framework supports not only the development of regulations, but also provides an underpinning for the establishment of creative and evolving management and compliance strategies. Elements of an effective legal framework include: A. A framework law that addresses wetlands as a specific ecosystem requiring directed management intervention, that links the primary enabling legislation to other relevant legal instruments directed at other programs and development processes. B. Subsidiary legislation that facilitates the development of an effective institutional framework. C. Guidance and guidelines to support the use of a wide range of measures and instruments (regulatory, fiscal, and non-fiscal) to enable effective management interventions. Appropriate Institutional Framework Although one public sector institution will be given the responsibility of being the lead agency for coordination of a territorial program, effective management will include collaborative arrangements between several public, private, and civil society institutions. An appropriate institutional framework will address the following: A. Collaborative programming, to assist in resolving conflicts, assist in making decisions relating to trade-offs, clarify roles and responsibilities of different stakeholders, and facilitate diverse stakeholder involvement. B. Development of an institutional coordinating mechanism that facilitates harmonization of management arrangements and institutional cultures (planning and decision-making systems, legal requirements in the various regulatory processes, reporting requirements and mechanisms, etc.). C. Shared information collection and management systems. Management Strategy The territorial management strategy is meant to provide strategic focus, translating the policy framework into strategic directions for wetlands management over an agreed period. The territorial strategy should: 2018 USVI Integrated Report A. Provide a structured framework for wetlands management, establishing the goals and objectives of the territorial program, and establishing guidelines and practices that link site management interventions to system management goals and objectives. B. Facilitate integration with other relevant planning strategies, such as those for tourism, biodiversity conservation, and protected areas. C. Facilitate integration with the economic development strategies and development control processes. D. Provide guidance on the design and implementation of a public engagement strategy. E. Provide a structured approach for coordinating the initiatives of the various institutions implementing wetlands-related activities. F. Provide a broader perspective for addressing site-specific issues. Management Plan/Action Plan The wetlands management plan is the action plan for the strategy period, and should: A. Identify priority interventions for the strategy period, setting targets and identifying milestones. B. Assign institutional roles within each area of intervention. C. Establish coordinating mechanisms and structures. D. Identify resource requirements. E. Establish monitoring and evaluation guidelines and procedures for the implementation of the management plan/action plan Institutional Program/Annual Plan Each institution with assigned roles in the management plan/action plan should establish an institutional plan designed to: A. Fulfill the institution’s obligations identified in the Wetlands Strategy and Management Plan. B. Be responsive to the institution’s legal mandate. 2018 USVI Integrated Report 7. IMPLEMENTATION AGENDA If the above program elements are used as the guide for the development of a wetlands management program for the USVI, the process of development of an appropriate wetland policy will take a minimum of five (5) years. As such, establishment of some elements will proceed apace, rather than wait on the completion of the policy process. The following actions are proposed as the initial steps in the development of the wetlands management framework for the USVI: 1. Preparation of a Draft Wetlands Policy. 2. Preparation of a Wetlands Management Strategy and Action Plan. 3. Design of inter-agency management framework and preparation of an associated collaborative agreement. 4. Preparation of institutional work plans. 5. Development of data management policies and data management mechanisms1. 6. Establishment of framework management support systems (planning, communications, etc.). 7. Establishment and testing of data management system. 8. Preparation of first biennial Territorial Wetlands Report. 9. Preparation of a 5-year work plan. 10. Preparation of program financing strategy and plan. 11. Convene workshop (finalize report and work plan). H. Water Quality Management Program The Water Quality Management (WQM) Program was created in 2000. Under the Water Quality Management & Planning (WQM&P) Grant (pursuant to CWA §604(b)), the V.I. DPNR-DEP is entrusted with the task of planning and implementing Water Quality Management Projects to ensure the protection of the marine waters of the USVI. Several duties that were formerly under the auspices of the Water Pollution Control (WPC) Program were placed under the WQM Program. In FY2009, WQM was merged with WPC. WQM is tasked with the following sub-programs: • COASTAL WATER QUALITY (AMBIENT) MONITORING PROGRAM • TMDL DEVELOPMENT AND IMPLEMENTATION PROGRAM • VIRGIN ISLANDS BEACH WATER QUALITY MONITORING PROGRAM • WATER QUALITY MANAGEMENT AND PLANNING GRANT PROGRAM 2018 USVI Integrated Report III. SURFACE WATER MONITORING & ASSESSMENT A. Surface Water Monitoring Program The Coastal Water Quality (Ambient) Monitoring Program is the primary mechanism for monitoring the Virgin Islands coastal water quality. The sampling locations on the fixed station network are monitored on a quarterly basis. WQM also manages the VI Beach Water Quality Monitoring (BEACH) Program which monitors up to 43 designated beaches throughout the Territory on a weekly basis. The Ambient and Beach Programs data are used to make water quality assessments on which this Integrated Report is based. All the monitoring locations are listed in Table III.A.1. The Storage and Retrieval of Water-Related Data (StoRet) program is managed and updated by WQM staff. The monitoring data is uploaded to StoRet via the Water Quality Exchange Network website, using the Web Template. The Assessment Database (ADB) was fully implemented once the Virgin Islands defined assessment units for more comprehensive water quality assessments. ADB is a valuable tool for storing assessment information (including all the assessment unit IDs and names, associated monitoring stations, category, class, designated use and the parameters it is impaired for, as well as additional metadata) and retrieving it for reporting purposes. DPNR traditionally populates an ADB Template in Microsoft Excel and submits it to USEPA for uploading into ADB. At the very end of FY 2017 (September 25, 2017), the USEPA released the TMDL Tracking And ImplementatioN System (ATTAINS) v1.0. Uploading the data into ATTAINS was not performed at the end of FY2017 as the program had just been released and operations in the USVI were disrupted by two Category 5 Hurricanes. However, inputting data into ATTAINS occurred at the end of FY2018 and the 303(d) draft list was public noticed via ATTAINS. Going forward, ATTAINS will replace the ADB. DPNR-DEP work plans require quarterly monitoring of 138 near-shore monitoring sites, and 26 off- shore monitoring sites, for a total of 164 stations throughout the USVI. There are sixty-eight (68) stations around St. Croix, sixty-nine (69) stations around St. Thomas, and twenty-seven (27) around St. John. These sites are located offshore and are sampled by EPA contractors using a vessel. DPNR- DEP expanded the monitoring network to include deep-water offshore sites at the outer rim of the USVI’s three-mile boundary. 1. Ambient Monitoring During this reporting period Ambient Monitoring was conducted for 4 quarters throughout the Territory during FY2016, for 4 quarters during FY2017 in St. Croix Assessment Units (AU), and for 3 quarters in St. Thomas and St. John Assessment Units by an EPA-selected contractor. DPNR also collected ambient data using internal staff for 1 quarter in all Assessment Units during FY2016. 2018 USVI Integrated Report i. Monitoring Sites Table III.A.1.

Monitoring Measurements At each station, field (in-situ) measurements included the following: Turbidity: expressed in Nephelometric Turbidity Units (NTU’s) measured 1 meter below the surface and 1 meter above the sea floor (or at the maximum depth of the instrument (approximately 30 m)) using a calibrated and EPA approved field instrument. Dissolved Oxygen: expressed in mg/L saturation and measured 1 meter below the surface and 1 meter above the sea floor (or at the maximum depth of the instrument (approximately 30 m)) with an EPA approved and calibrated field instrument. pH: expressed in Standard Units (SU) measured 1 meter below the surface and 1 meter above the sea floor (or at the maximum depth of the instrument (approximately 30 m)) with an EPA approved and calibrated field instrument. Temperature: expressed in degrees Centigrade measured 1 meter below the surface and 1 meter above the sea floor (or at the maximum depth of the instrument (approximately 30 m)) with an EPA approved and calibrated field instrument. 2018 USVI Integrated Report Salinity: expressed in parts per thousand and measured 1 meter below the surface and 1 meter above the sea floor (or at the maximum depth of the instrument (approximately 30 m)). Secchi Depth: expressed in meters by a Secchi depth measuring light transparency. Bacteria: Water samples were collected by surface grab samples at each station on a quarterly basis and taken to a DPNR certified laboratory where they were analyzed for Enterococci bacteria. Results were expressed as number of colonies per 100 milliliters. Analysis was performed utilizing an EPA approved methodology. The geometric mean was also factored in before it was determined whether an assessment met the water quality standard. Total Suspended Solids: Water samples were collected by surface grab samples at each station on a quarterly basis and taken to a DPNR certified laboratory where they were analyzed utilizing an EPA approved methodology. Total Phosphorous: Water samples were collected by surface grab samples at each station and taken to a DPNR certified laboratory where they were analyzed utilizing an EPA approved methodology. DPNR-DEP is working to increase the sampling frequency for this parameter. A lack of resources has resulted in limited sampling. Currently, the local lab is being checked for quality assurance issues and the efficiency of the methods used is also being evaluated. Once these issues are assessed, it is anticipated that the monitoring frequency will be increased. 2. Beach Monitoring WQMP also monitors designated recreational beaches on a weekly basis through the Beach Water Quality Monitoring Program (with several exceptions explained below). The Beach Water Quality Monitoring Program collected weekly samples at up to 43 designated beaches throughout the Territory for FY2016 and FY 2017 which were analyzed for Enterococci Bacteria and Turbidity (analyzed at the lab). ▪ Week ending 11/27/15 – No sampling done due to storm event. ▪ Week ending 12/4/15 – Sampling performed in STX and STJ only due to storm event in STT. ▪ Week ending 12/11/15 – Sampling performed in STX only due to storm event in STT & STJ ▪ Week ending 12/23/15 – Sampling performed in STX only due to early lab closure in the STT district. ▪ Week ending 12/31/15 – No sampling done due to lab closure in both districts. ▪ Week ending 1/15/16 – Sampling performed in STT, STJ and half of STX only due to heavy wave action at various beaches on STX. ▪ Week ending 4/1/16 – Sampling performed in STX only due to storm event. ▪ Week ending 4/15/16 – Sampling performed in STX only due to no staff in STT district due to BEACH Conference attendance. 2018 USVI Integrated Report ▪ Week ending 7/29/16 – Sampling performed in STX only due to no staff available in STT district ▪ Week ending 8/5/16 – No sampling done due to STX lab closure and no staff available in STT district. ▪ Week ending 8/26/16 – Sampling performed in STT and STJ only due to storm event. ▪ Week ending 9/2/16 – Sampling performed in STX only due to no staff available in STT district. ▪ Week ending 9/9/16 – No sampling done due to lab refusal of service in both districts. ▪ Week ending 9/16/16 – Sampling performed in STT and STJ only due to lab refusal of service in both districts.

Other Ambient Monitoring Activities i. Toxics/biological monitoring No baseline or routine monitoring for toxics or biological effects is conducted in the Virgin Islands by the DEP. However, the University of the Virgin Islands (UVI) in conjunction with the NOAA Coral Reef Conservation Program, NOAA Protected Species, and the USVI Department of Planning and Natural Resources (CZM division), continue to conduct annual to semi-annual assessments of coral health, benthic community structure, fish community structure, and physical dynamics throughout Territorial waters. These studies augment the data repository for use in future bio- assessment and criteria development. According to the Virgin Islands Multi-Year Monitoring Strategy (MYMS), DPNR-DEP will explore options for implementing a biological component of the Ambient Monitoring Program and feeding this into a database for eventual biocriteria development. Biological data pertaining to fish populations and coral reef health, diversity and other parameters may be collected during Ambient sampling events at selected sites to correlate with water quality data. This may include developing a partnership with NOAA, UVI or another agency with similar monitoring objectives. Numeric water quality criteria for toxic pollutants (as found in the EPAs national recommended Clean Water Act section 304(a) water quality criteria) have been adopted into the Virgin Islands Water Quality Standards Rules and Regulations. However, no baseline or routine monitoring for toxics is currently scheduled to be incorporated into the DEP Ambient monitoring program in the immediate future, for eventual integration into the development of Virgin Islands specific water quality criteria for toxic pollutants. ii. Fish tissue, sediment, and shellfish monitoring: The Virgin Islands Water Pollution Control program does not monitor fish tissue, sediment or shellfish for toxicity. A background analysis of ambient water quality has not yet been performed to support the adoption of biological criteria for toxic chemicals (1996 VI 305(b)). iii. Quality assurance/quality control program The US Virgin Islands DPNR-DEP’s Quality Assurance (QA) Program is committed to assuring and improving the quality of all environmental measurements performed by and for the Department. The goal of the QA program is for the acquisition of reliable and defensible environmental data. It is the policy of DPNR that adequate QA activities are conducted within the agency to ensure that all environmental data generated and processed are scientifically valid, of known precision and accuracy, of acceptable completeness, representativeness and comparability and, where appropriate, legally defensible. During Fiscal Years 2016 and 2017 QA activities such as program technical audits, file audits, revision of the Quality Assurance Management Plan, Management System Reviews, review of program and contractual Quality Assurance Project Plans, review of all program Standard Operating 2018 USVI Integrated Report Procedures, and Laboratory Certifications were performed. DPNR has a full-time QA/QC Officer who also acts as the Laboratory Certification Officer for the Department. iv. Volunteer monitoring DPNR had no monitoring volunteers during the reporting period. Volunteer monitoring, however, is being planned for implementation in future water quality monitoring program activities. v. Program evaluation • The Ambient water quality monitoring program continues to be conducted throughout a fixed network of monitoring stations in embayments, nearshore and offshore Territorial waters by EPA contractors. It is the aim of the DEP to regain sampling/monitoring privileges in FY18 to FY19 and to reevaluate the network of monitoring stations to determine where improvements may be made; • The BEACH monitoring program continues to be conducted throughout a fixed network of 43 designated beaches. It is the aim of the DEP to reevaluate designated beaches in FY18 to FY19 in order to ascertain if the tiered system needs modification, or beaches should be added or removed. This would be done through thorough detailed beach evaluations, evaluating number of beachgoers, frequency of exceedances, general beach activities, and location over the course of 6-12 months; • No baseline or routine monitoring for toxics is conducted in the Virgin Islands by the DEP. A background analysis of ambient water quality is needed to support the adoption of specific biological criteria for toxic pollutants (1998 305(b) Report). As part of the 2015 US Virgin Islands Water Quality Standards revision, the national recommended criteria were adopted; • DPNR-DEP intends to explore options for implementing a biological component of the Ambient Monitoring Program and using this data for eventual biocriteria development; • New equipment and staff training is needed to assess water quality for the development of toxic and biological criteria (1998 305(b) Report); • Revisions to the Water Quality Standards and criteria are needed to include numeric values instead of narrative description of desired water quality for biological condition and toxic pollutants. 2018 USVI Integrated Report 4. Storage and Retrieval Program (STORET) During this reporting cycle, DPNR-DEP used the WQX_Web Template to catalog its water quality monitoring data. After the template was populated, DPNR-DEP uploaded it to the Water Quality Exchange from which it can be queried using StoRet. All data used to make assessments in this Integrated Report has been uploaded into WQX Web. FY2016 Data collected during Basic Water Quality Monitoring (BWQM) (the “Ambient” program) was entered into the WQX Web Template for uploading into WQX Web by the USEPA Contractor. The weekly Beach Water Quality Monitoring data were entered into the WQX Web Template for upload to the WQX Web by DEP personnel. FY2017 Data collected during BWQM was entered into the WQX Web Template for uploading into WQX Web by the USEPA Contractor. The weekly Beach Water Quality Monitoring data were entered into the WQX Web Template for upload to the WQX Web by DEP personnel. B. Assessment Methodology Purpose: The Clean Water Act requires each state to conduct water quality surveys to determine if its waters are healthy and have sufficient quality to meet their designated uses and attain water quality standards. A report on this water quality assessment is submitted every two years to US Environmental Protection Agency – Region 2. The U.S. Environmental Protection Agency (USEPA) encourages states to adopt the Integrated Reporting format which blends elements of the 305(b) Water Quality Assessment Report and the 303(d) Impaired Waterbody List. The United States Virgin Islands Department of Planning and Natural Resources (DPNR-DEP) uses this format to more accurately and completely assess USVI’s waterbodies. States are required to submit, for USEPA and public review, the methods used to collect, analyze, and interpret data to determine compliance with applicable water quality standards and assess support of the applicable designated uses. This Method document serves that function by providing an objective and scientifically sound assessment methodology. Complete assessments include: Identification of waterbody type. All waters of the U.S. Virgin Islands shall meet generally accepted aesthetic qualifications and shall be capable of supporting diversified aquatic life. The waters within the jurisdiction of the United States Virgin Islands include: all harbors, bays, streams, lakes, ponds, impounding reservoirs, marshes, water-courses, water-ways, wells, springs, irrigation systems, drainage systems and all other 2018 USVI Integrated Report bodies or accumulations of water, surface and underground, natural or artificial, public or private, situated wholly or partly within or bordering upon the United States Virgin Islands, including the territorial seas, contiguous zones, and oceans. Assessments of these “waters” shall be included in the U.S. Virgin Islands 2018 Integrated Report, with emphasis given to the waterbodies inland, near- shore and off-shore from the three major islands making up the U.S. Virgin Islands: St Croix, St Thomas and St John. All available groundwater data will be reviewed for possible inclusion in the report and the Division of Environmental Protection’s Groundwater Program will provide groundwater discussion in the 2018 Integrated Report. Identification of waterbody classification and designated use. According to the 2015 U.S. Virgin Islands Water Quality Standards (WQS), the waters of the Virgin Islands exist in one of four classes: I, A, B and C. The geographical extent of the four waterbody classes, and the applicable water quality standards are found at the following website: http://dpnr.vi.gov/environmental-protection/water-quality-management/ Or, via navigation from https://dpnr.vi.gov Inventory of physical, chemical and microbiological data The Division of Environmental Protection’s Coastal Water Quality (Ambient) Monitoring Program is managed by the Water Quality Management Program (WQMP). Through the Coastal Water Quality Monitoring Program, ambient water quality is monitored on a quarterly basis, WQMP also monitors designated recreational beaches on a weekly basis through the Beach Water Quality Monitoring Program. Through an In-Kind Assistance Agreement, USEPA contractor was responsible for conducting quarterly Ambient Monitoring for FY16-17, although one quarter of additional data was collected by DPNR staff in FY16. The inventory of physical, chemical and microbiological data used to develop the 2018 Integrated Report and make water quality assessments are StoRet data extracts from fiscal years 2016-2017 (October 1, 2015 to September 30, 2017) from the Ambient and Beach Water Quality Monitoring Programs. The parameters used to perform the assessments are those parameters which were analyzed by the Ocean Systems Laboratory, University of the Virgin Islands’ Environmental Analysis Laboratory, Pace Analytical Laboratory and USEPA Region II Laboratory. These parameters include: Enterococci, Turbidity, pH, Dissolved Oxygen and Total Phosphorus. Habitat assessment data inventory The US Virgin Islands Division of Fish and Wildlife has been identified as a possible data source for habitat assessments. However, there is no habitat assessment data available at this time. If data is available in the future it will be included in future water quality assessment reports. 2018 USVI Integrated Report Visual Data Sources The Department of Planning and Natural Resources, Division of Environmental Protection keeps a log of all incidents of oil spills, fish kills and other events that had a negative impact on the water quality in the US Virgin Islands. It was determined that there were no visual data sources to be reported on or included for this reporting cycle. Identify exceedances of water quality standards The U.S. Virgin Islands water quality standards set limits for various criteria. All readily available data that meet quality assurance/quality control requirements will be compared to the limits set by the USVI water quality standards to determine which waterbodies exceed these limits. During this reporting cycle the parameters listed below were assessed in the following manner: Parameter Source Data Type Assessment Method Enterococci Ambient The 30-day geometric mean for enterococci shall not exceed 30 CFU/100 mL and no more than 10 percent of the samples collected in the same 30 days shall exceed 110 CFU/100 mL. Beach Turbidity Ambient A maximum nephelometric turbidity unit reading of three (3) shall be permissible, and secchi disk reading of minimum of 1 meter. Beach Ambient *For areas where coral reef ecosystems are located, a maximum nephelometric turbidity unit reading of one (1) shall be permissible, and secchi disk reading of minimum of 1 meter. Beach Total Phosphorus Ambient Shall not exceed 50 µg/l pH Ambient Class A, B: Range shall not be outside 7.0 to 8.3 standard units Class C: Range shall not be outside 6.7 to 8.5 standard units Dissolved Oxygen Ambient Class A, B: Shall be no less than 5.5 mg/L Class C: Shall be no less than 5.0 mg/L Temperature Ambient Shall not exceed 32 degrees Celsius at any time, nor as a result of waste discharge to be greater than 1.0°C above natural conditions *For areas where coral reef ecosystems are located, shall not exceed 25-29°C at any time, nor as a result of waste discharge to be greater than 1.0°C above natural. *Areas that contain coral reef ecosystems are determined based on Benthic Habitat Atlas of Puerto Rico and the U.S. Virgin Islands (2002) 2018 USVI Integrated Report Designated Use Attainment The VI Water Quality Standards identify specific designated uses for the waters of the U.S. Virgin Islands according to their waterbody classifications. Designated uses include: • maintenance and propagation of desirable species of aquatic life (including threatened, endangered species listed pursuant to section 4 of the federal Endangered Species Act and threatened, endangered and indigenous species listed pursuant Title 12, Chapter 2 of the Virgin Islands Code) • primary contact recreation (swimming, water skiing, etc.). The Department uses both numeric and narrative criteria to protect designated uses. Numeric criteria are estimates of constituent concentrations that are protective of the designated uses. Narrative criteria are non-numeric descriptions of conditions to be attained/maintained or avoided. Parameters for Designated Use Assessments Evaluation of this reporting cycle’s data has determined that the following parameters be used to perform assessments: Designated Use Minimum Parameters Used For Assessments Source Data Type • Maintenance and propagation of desirable species of aquatic life • Primary Contact Recreation Enterococci Ambient Beach Turbidity (Laboratory-generated) Beach Total Phosphorus Ambient Dissolved Oxygen Ambient Turbidity (Multi-parameter Sonde) Ambient pH Ambient Temperature Ambient Data gaps and error control It is understood that the US Virgin Islands has a number of data gaps. These gaps are not limited to existing data sets, but it can also refer to the lack of certain types of data; additionally, disclaimer language will be added to ensure that everyone who reviews the document is clear about the data used to make assessments. The table below lists potential data gaps which DPNR intends to work on developing a data document in collaboration with EPA Region 2 in the near future. Any data gaps that are identified will be included in the multi-year monitoring strategy for resolution. 2018 USVI Integrated Report Future Assessment Methodologies to be Included Timeframe for inclusion Toxicity and toxicant data See Section 1.4 & Appendix A of the USVI MYMS for details Wetland assessment data See Section 1.4, 4.3 & Appendix A of the USVI MYMS for details Intermittent streams data See Appendix A of the USVI MYMS for details “Natural” levels relative to the DO and temperature standards See Appendix A of the USVI MYMS for details Narrative criteria, as listed in Section 186-1(c) of the VI WQS Regulations See Appendix A of the USVI MYMS for details Radioactivity data See Appendix A of the USVI MYMS for details The US Virgin Islands will make every effort to control errors that may have been reported in data. Data determined to be erroneous or flawed based on the program’s data quality objectives established in the Coastal Water Quality Monitoring (Ambient) and Beach Water Quality Monitoring Programs Quality Assurance Project Plans will be discarded. Evaluation of this reporting cycle has determined that the following parameters be used to perform assessments: Minimum Parameters Used For Assessments Source Data Type Enteroccoci Ambient Beach Turbidity (Laboratory-generated) Beach Total Phosphorus Ambient Dissolved Oxygen Ambient Turbidity (Multi-parameter Sonde) Ambient pH Ambient Temperature Ambient Natural Disasters Hurricane season in the U.S. Virgin Islands lasts from June through November each year. There was no sampling during this reporting cycle related to natural disasters. However, the following storm and associated sampling events occurred: FY16 No episodic monitoring conducted FY17 Hurricane Irma: September 6, 2017 - Conducted Beach/Coastal Assessments 2018 USVI Integrated Report Hurricane Maria: September 19, 2017- Conducted Beach/Coastal Assessments (no conditional sampling done until FY18) Evaluation of Internal Data Ambient (Coastal Water Quality) Data was collected for 4 quarters throughout the Territory during FY2016. Ambient Data was collected for 4 quarters during FY2017 in St. Croix Assessment Units (AU), and for 3 quarters in St. Thomas and St. John Assessment Units by an EPA-selected contractor. DPNR also collected ambient data using internal staff for 1 quarter in all Assessment Units during FY2016. DPNR will use all these datasets, giving a total evaluation of eight (8) sets of monitoring data for the St. Thomas and St. John AUs, and nine (9) sets of monitoring data for the St. Croix AUs. The Beach Water Quality Monitoring Program collected weekly samples at 43 designated beaches throughout the Territory which were analyzed for Enterococci Bacteria and Turbidity (analyzed at the lab). Data received during the 2018 Integrated Report Data Solicitation Process announced on November 2, 2015; and Analytical Data for bacteria grab samples, Total Phosphorus and turbidity (analyzed at the lab), as well as, dissolved oxygen, turbidity, pH and temperature (analyzed by multi- parameter) to make assessments for the 2018 Integrated Report. The data used for assessments were uploaded to the StoRet Database via the Water Quality Exchange. The figures below display DPNR’s monitoring locations for its Ambient and Beach Programs: St. Croix Water Quality Monitoring Network 2018 USVI Integrated Report St. Thomas/St. John Water Quality Monitoring Network DPNR evaluates all internal monitoring data to determine if the Data Quality Objectives outlined in the USVI Ambient Water Quality Monitoring Program Quality Assurance Project Plan are met i.e. compliance with the Relative Percent Difference (RPD) of 30 or less. Once the data is determined to meet the required objectives, for example the RPD, the data is used to conduct the assessments for the reporting cycle. The elements evaluated are as follows: Precision The precision of data are determined by particular actions of the analytical laboratory and field staff, which are outlined in the relative SOPs and QAPPs. WQM staff ensures timely and efficient calibration and maintenance of the multi-parameter sonde, in accordance with DPNR-DEP’s YSI 6600 Sonde Operation and Maintenance - SOP. The WQM staff also assures that water samples and related field data are collected at the right locations. Once at the prescribed location staff makes every effort to record field data accurately and entered into the databases for uploading to EPA StoRet, in accordance with the WQX_Web Data Entry SOP. Staff collect field samples in a manner that would limit or prevent sample contamination and deliver samples to laboratory within sufficient time such that the samples can be analyzed within the correct holding time. Staff also fill out required field and lab submittal paperwork, which is also in accordance with the Data Collection and Sample Handling – Ambient Water Quality Monitoring SOP. After data is analyzed and results are received from the laboratory all documents are stored in accordance with Filing of Ambient Field Data Forms and Associated Paperwork SOP. 2018 USVI Integrated Report The precision of data is a measure of the reproducibility of the measurement when an analysis is repeated. The precision of selected chemical analyses will be examined by using standard solutions and comparison of duplicate analysis. Relative percent difference (RPD) will be calculated for field duplicate analysis to assess precision of field collection procedure. Laboratory precision will be determined by calculating RPD of results of “unknown” analysis and laboratory duplicate analysis. The acceptable RPD is 30 or less. The following is the formula used for calculation of RPD: RPD = {(C1 - C2)/[ (C1 + C2)/2]} x 100 RPD= Relative Percent Difference C1= Larger of two observed values C2= Smaller of two observe values Representativeness The representativeness of the data is mainly dependent on the sampling locations and the sampling procedures adequately representing the true condition of the sample site. Sampling station siting and use of only approved/documented analytical methods will determine that the measurement data represent the conditions at the site, to the extent possible. Sampling schedules will be designed with respect to frequency, locations and methodology in order to maximize representativeness, where possible and applicable. Laboratory representativeness will be achieved by following analytical procedure and standard operating procedures, meeting holding times, and assessment and comparison of field duplicate samples. Comparability The comparability of data produced by and for DPNR is predetermined by the commitment of its staff and analytical laboratories to use standardized methods, where possible, including EPA approved analytical methods, or documented modifications thereof which provide equal or better results. These methods have specified units in which the results are to be reported. Completeness The completeness of data is a relationship of how much of the data is available for use compared to the total potential data before any conclusion is reached. Ideally, 100% of the data should be available. However, the possibility of data becoming unavailable due to laboratory error, insufficient sample volume, or samples broken in shipping must be expected. Also, unexpected situations may arise where field conditions do not allow for 100% data completeness. Failure to achieve 100% data completeness usually will result from the field crew’s inability to sample at stations because of logistical barriers, such as insufficient depth, or adverse weather conditions. In the limited number of instances where these may be encountered, efforts will be made to relocate the station in an adjacent area or re-sample the station. In addition, established protocols for tracking samples during shipment and laboratory processing must be followed to minimize data loss following successful sample 2018 USVI Integrated Report collection. The Department has various completeness goals: 100% for data collection and data usage, which directly correlates to a 100% goal for data used to make assessments. However, if less than 8 data points are collected for a particular assessment unit, then the Department will not be able to de- list those assessment units eligible for delisting. It is the responsibility of the program manager to verify that the data are representative, and completeness is achieved while the analytical data's precision, accuracy, and comparability are mainly the responsibility of the laboratory supervisor. Data From Other Sources DPNR will consider data received during its Data Solicitation period for the submission of the draft 303(d) Total Maximum Daily Load List. All data received will be reviewed for credibility and if determined to be of high quality and of great significance it may be added as an appendix. Otherwise, the data received after solicitation process will be considered during the next cycle. Other data sources refer to any data that was collected outside of the U.S. Virgin Islands Department of Planning & Natural Resources. The following agencies were contacted to request data during the Data Solicitation Period. The agencies were asked to submit all relative monitoring data for the monitoring period with the associated Quality Assurance Project Plan: Contact Organization Data Submitted Kofi Boateng UVI-CES No data submitted.

Once received the QAPP and data would be evaluated to determine if DPNR’s Data Quality Objectives were met. If the data is determined to be acceptable then the data would be used in the reporting cycle’s assessments. A rationale for any decision to not use any existing and readily available data and information would also be included in the Integrated Report. DPNR intends to develop a Standard Operating Procedure for the evaluation of secondary data which will clearly articulate acceptance criteria. That criteria once developed will be incorporated into the relative version of the Assessment Methodology. DPNR received only one set of data from outside agencies; however, that data could not be used as it was from interstitial water samples, and DPNR does not currently have classifications for, water quality criteria for, or assess interstitial waters. Monitored Waters The coastal waters of the Virgin Islands are evaluated for the following uses: Primary Contact Recreation and Aquatic Life Use Support. All existing and readily available data and information will be assembled and used in the assessment. Island # of Assessment Units (AUs) AUs Monitored # of AUs each Class of Water falls under % of Total Total Class A Class B Class C St. Croix 84 37 1 30 6 44% St. Thomas 59 42 0 39 3 71% St. John 33 17 0 17 0 52% * AUs not monitored were either missed during monitoring events or currently do not have monitoring locations within them Use Support Determination Waterbody delineations used for determining use support are derived from global information system (GIS) coverages. The Division of Environmental Protection is currently considering contracting professional services to develop a revised standard waterbody delineation based on a number of prevailing factors. Presently, use support will be determined using the most current version of the US Virgin Islands Water Quality Standards which was promulgated on August 28, 2015. The current use determinations are as follows: 2018 USVI Integrated Report § 186-2. Class A (a) Designated uses: Maintenance and propagation of desirable species of aquatic life (including threatened, endangered species listed pursuant to section 4 of the Federal Endangered Species Act and threatened, endangered and indigenous species listed pursuant Title 12, Chapter 2 of the Virgin Islands Code) and primary contact recreation. Preservation of the unique characteristics of the waters designated as Outstanding Natural Resource Waters (e.g., Natural Barrier Reef at Buck Island, St. Croix and the Under Water Trail at Trunk Bay, St. John), waters of exceptional recreational, environmental, or ecological significance. The quality of these waters cannot be altered except towards natural conditions. No new or increased dischargers shall be permitted. § 186-3. Class B (a) Designated uses: Maintenance and propagation of desirable species of aquatic life (including threatened, endangered species listed pursuant to section 4 of the Federal Endangered Species Act and threatened, endangered and indigenous species listed pursuant Title 12, Chapter 2 of the Virgin Islands Code) and primary contact recreation (swimming, water skiing, etc.). This Class allows minimal changes in structure of the biotic community and minimal changes in ecosystem function. Virtually all native taxa are maintained with some changes in biomass and/or abundance; ecosystem functions are fully maintained within the range of natural variability. § 186-4. Class C (a) Designated uses: Maintenance and propagation of desirable species of aquatic life (including threatened and endangered species listed pursuant to section 4 of the Federal Endangered Species Act and threatened, endangered and indigenous species listed pursuant Title 12, Chapter 2 of the Virgin Islands Code), primary contact recreation (swimming, water skiing, etc.), industrial water supplies, and shipping, and navigation. This Class allows for evident changes in structure of the biotic community and minimal changes in ecosystem function. Evident changes in structure due to loss of some rare native taxa; shifts in relative abundance of taxa (community structure) are allowed but sensitive-ubiquitous taxa remain common and abundant; ecosystem functions are fully maintained through redundant attributes of the system. Ground Water Assessment Groundwater Monitoring Program WQM is not tasked with monitoring the groundwaters of the USVI. WQM has been informed by DPNR-DEP’s Groundwater Program that the only groundwaters that are monitored throughout the Territory are those that are potable water sources. The monitoring is required through DPNR-DEP’s Public Water Systems Supervision Program. 2018 USVI Integrated Report Surface Water Assessment As part of the assessment process, each assessment is rated as being supporting, partially supporting, not supporting or not applicable (not applicable is usually the result of a data gap). Under the integrated reporting format, partially supporting and not supporting are both considered impaired and will be listed under category 5 provided water quality standards are exceeded. The USVI uses partially supporting only as a measure of impairment severity. Severity is important in helping the USVI design a schedule for total maximum daily loads. While partially supporting waters are listed as impaired, not supporting waters are listed as impaired and threatened. In order to assess an assessment unit, data must be available for at least one applicable parameter associated with the attainment of the given designated use. Impairment of any single indicator will result in the waterbody being listed as impaired (for that parameter), even if the other indicators do not exceed the standards. Consideration will be taken in cases where a parameter falls within the degree of error of monitoring equipment; the data will be reviewed and if the value is within the instrumentation’s degree of error it will be accepted. If after the instrument’s degree of error is considered the parameter is still found to be an exceedence it will be considered as such. 1. Primary Contact Recreation Microbiological Assessment The use support is based on a review of quarterly ambient and weekly beach data for both the Statistical Threshold Value (STV) as well as Geometric Mean (GM) of enterococci bacteria, beach closing data and reported oil spills. Allowable limits are the same for all classes of waters: a geometric mean of 30 CFU per 100 mL, or a STV exceedance of 110 CFU/100 mL in more than 10 percent of the samples collected in the same 30 days. The percent of total violations is evaluated as follows: 1. Fully Supporting: None of the Samples exceed a geometric mean of 30 CFU/100 ml in all class waters and no exceedance of 110 CFU/100 mL in more than 10 percent of the samples collected in the same 30 days. 2. Not supporting: Any of the Samples exceed a geometric mean of 30 CFU/100 ml in any class waters and exceedance of 110 CFU/100 mL in more than 10 percent of the samples collected in the same 30 days. Beach Closing Assessment In addition to pathogens, beach-closing data will be used to determine primary contact recreation use support. The matrix of allowable violations is as follows: 2018 USVI Integrated Report 1. Supporting: No bathing area closures or restrictions in effect during reporting period. 2. Not Supporting: On average, one bathing area closure per year of greater than 1 week’s duration, or more than one bathing area closure per year. * Closure as stated above refers to the VI Department of Health or VI Waste Management Authority closing beaches due to immediate health risks or threats. While, restrictions refer to advisories which may recommend that the public avoid certain areas/beaches. The Department of Planning and Natural Resources only issues administrative advisories and cannot restrict beach access. Beach closures would only be enforced by government enforcement officials for very serious threats to human health; these closures can only be implemented by the VI Department of Health or the VI Waste Management Authority. These serious threats are usually related to bypasses or overflows of the municipal sewer system, which may result in raw sewage flowing onto beaches and into the nearshore/bathing areas. DEP has implemented a Beaches Environmental Assessment and Coastal Health (BEACH) Monitoring Program that takes samples for Enterococci at select sites on a weekly basis. This data will be used in conjunction with data collected from the Ambient Monitoring Program. Beaches which are listed as not suitable for fishing or swimming in the weekly Beach Program have had samples collected which exceed the standard within that monitoring week. Those beaches that are re- sampled according to the BEACH QAPP and exceed the standard twice within that monitoring week shall be listed as well. Toxicant Assessment (Human Health and Aquatic Life)/ Toxicity Assessment The applicable numeric water quality standards for toxic pollutants to protect the designated uses of waters of the U.S. Virgin Islands shall be the Environmental Protection Agency's (EPA) national recommended Clean Water Act section 304(a) water quality criteria, EPA's Office of Water, Office of Science and Technology (4304T), 2006. Those parameters can be found at the following website: <http://www.epa.gov/waterscience/criteria/wqctable/index.html> The conditions for use support are as follows: 1. Fully Supporting: No toxicants or toxicity noted in either acute or chronic tests compared to controls or reference conditions. 2. Partially Supporting: No toxicants or toxicity noted in acute tests but may be present in chronic tests in either slight amounts and/or infrequently within an annual cycle. 3. Not Supporting: Toxicants or toxicity noted in many tests and occurs frequently. Currently DPNR-DEP does not collect any toxicity data, and none was received during the data solicitation period. Therefore, no assessments were made based on toxicants or toxicity during this 2018 USVI Integrated Report reporting period. DPNR-DEP will continue to review its criteria for these assessments and will work to improve upon the current criteria to ensure they are relevant to the assessment of human health. Additionally, as DPNR-DEP works to expand the VI Water Quality Standards this section will continue to be amended. Other Parameters Throughout the course of collecting data for this report, data that does not fit within the auspices of the other assessment categories of Primary Contact Recreation Use Support (e.g. aesthetics, pH, turbidity, algae, odor, etc.) will be considered under Other Parameters. The following guidelines apply where appropriate: 1. Fully Supporting: For any one pollutant or stressor, criteria exceeded in none of the measurements. 2. Not Supporting: For any one pollutant, criteria exceeded in any of measurements. DPNR-DEP intends to continue to work towards in developing expanded criteria for making assessments within this category. There were no assessments made for this category during this reporting cycle. Habitat Assessment Determination of Aquatic Life Use Support will consider habitat assessment data (based on availability) in relation to propagation of desired species of marine life and the biological integrity of the benthic communities living within waters. These communities shall be assessed by comparison to reference conditions(s) with similar abiotic and biotic environmental settings that represent the optimal or least disturbed condition for that system. Such reference conditions shall be those observed to support the greatest community diversity, and abundance of aquatic life as is expected to be or has been historically found in natural settings essentially undisturbed or minimally disturbed by human impacts, development, or discharges. Habitat assessment data is considered as follows: 1. Fully Supporting: Reliable data indicate natural channel morphology, substrate composition, bank/riparian structure, and flow regime of region. Riparian vegetation of natural types and of relatively full standing crop biomass (i.e., minimal grazing or disruptive pressure). 2. Partially Supporting: Modification of habitat slight to moderate usually due to road crossings, limited riparian zones because of encroaching land use patterns, and some watershed erosion. Channel modification slight to moderate. 2018 USVI Integrated Report 3. Not Supporting: Moderate to severe habitat alteration by channelization and dredging activities, removal of riparian vegetation, bank failure, heavy watershed erosion or alteration of flow regime and inclusion of exotic or aquatic nuisance species DPNR-DEP received no habitat assessment data for the 2016-2017 reporting cycle. However, DPNR has established a work group to begin to discuss correlations between water quality and various indicator species. As DPNR-DEP continues its ongoing efforts to improve the VI Water Quality Standards, criteria will be set for reference conditions/sites which will assist in completing habitat assessments for various waterbody classes. Conventional Assessment Conventional parameters are evaluated using the number of exceedances of water quality standards. A waterbody is determined to be impaired if there is an exceedance of a specific parameter two (2) or more times within the chosen dataset. The conventional parameters are: • Dissolved Oxygen (not less than 5.5 mg/l from other than natural conditions in Class A & B, not less than 5.0 mg/l from other than natural conditions in Class C) *; • Temperature (not to exceed 32°C at any time, nor as a result of waste discharge to be greater than 1.0°C above natural conditions; in areas where coral reef ecosystems are located**, not to exceed 25-29°C at any time, nor as a result of waste discharge to be greater than 1.0°C above natural conditions) *; • Turbidity (All Classes: shall not exceed 3 NTU and secchi disk reading of minimum of 1 meter; In areas where coral reef ecosystems are located**: shall not exceed 1 NTU and secchi disk reading of minimum of 1 meter); and • pH. (Class A, B: Range shall not be outside 7.0 to 8.3 standard units; Class C: Range shall not be outside 6.7 to 8.5 standard units) • Total Phosphorus (All Classes: shall not exceed 50 µg/L in marine and coastal waters). *The term “natural condition” for Dissolved Oxygen and Temperature will be addressed through work in collaboration with the Environmental Protection Agency (EPA) for Class B and C waters during a future Triennial Review of the WQS. During that process DPNR-DEP will outline how they will define reference sites and establish reference conditions. Once developed these criteria will be incorporated into this Assessment Methodology. **Areas that contain coral reef ecosystems are determined based on Benthic Habitat Atlas of Puerto Rico and the U.S. Virgin Islands (2002). The conditions for use support for the conventional parameters are as follows: 2018 USVI Integrated Report 1. Fully Supporting: For any one pollutant or stressor, criteria exceeded in none of the measurements. 2. Not Supporting: For any one pollutant, criteria exceeded in any of the measurements two or more times within the chosen dataset. Biological Assessment When available, DPNR-DEP may use data collected/received from biological monitoring projects. Upon identifying a source of data to apply towards a biological assessment, the conditions for use support, which will be evaluated in accordance with the narrative Biocriteria outlined in the VI Water Quality Standards, as follows: 1. Fully Supporting: Reliable data indicate functioning, sustainable biological assemblages (e.g., fish, macroinvertebrates, or algae) none of which has been modified significantly beyond the natural range of the reference condition. 2. Partially Supporting: At least one assemblage (e.g., fish, macroinvertebrates, or algae) indicates moderate modification of the biological community compared to the reference condition. 3. Not Supporting: At least one assemblage indicates nonsupport. Data clearly indicates severe modification of the biological community compared to the reference condition. DEP received no biological data for the 2016-2017 reporting cycle, and no biocriteria assessments were undertaken in this assessment cycle. As DPNR-DEP continues its ongoing efforts to improve the VI Water Quality Standards, criteria will be set for reference conditions/sites which will assist in completing biocriteria assessements for various waterbody classes. DPNR-DEP is working on establishing a baseline for biotic communities in order to be able to better define above noted criteria such as “minimal”, “evident”, “modified significantly”, “moderate modification”, and “severe modification”. These communities shall be assessed by comparison to reference conditions(s) with similar abiotic and biotic environmental settings that represent the optimal or least disturbed condition for that system. Such reference conditions shall be those observed to support the greatest community diversity, and abundance of aquatic life as is expected to be or has been historically found in natural settings essentially undisturbed or minimally disturbed by human impacts, development, or discharges. This condition shall be determined by consistent sampling and reliable measures of selected indicator communities of flora and/or fauna and may be used in conjunction with other measures of water quality. Waters shall be of a sufficient quality to support a resident biological community as defined by metrics based upon reference conditions. These narrative biological criteria shall apply to fresh water, wetlands, estuarine, mangrove, seagrass, coral reef and other marine ecosystems based upon their respective reference conditions and metrics. 2018 USVI Integrated Report There is some ongoing Territory-wide biological monitoring of marine communities being done by the University of the Virgin Islands (UVI). Limited coral reef and fish monitoring in specific areas has also been conducted by other local and federal groups (University of the Virgin Islands, National Oceanographic and Atmospheric Administration, and US National Park Service). Through the University of the Virgin Islands (UVI) in conjunction with the NOAA Coral Reef Conservation Program, NOAA Protected Species, and the USVI Department of Planning and Natural Resources (CZM division), annual to semi-annual assessments of coral health, benthic community structure, fish community structure, and physical dynamics is done at 33 sites down to 65 m (220 ft) depth. These studies are done in an effort to create a data repository for use in future bio-assessment and criteria development. Data reports on these ongoing efforts, called the US Virgin Islands Territorial Coral Reef Monitoring Program (TCRMP), can be found here: https://sites.google.com/site/usvitcrmp/ Additionally, DPNR has conducted two phases of a project in collaboration with the University of the Virgin Islands to correlate water quality and coral health. These projects were funded by Supplemental 106 Funds and were completed between FY10-14. DPNR intends to fund a third phase of this biological study using additional Supplemental 106 Funds. Listing Rules Minimum Number of Samples: Unless described differently for a particular parameter, the minimum data set consists of eight (8) samples. These recommendations are intended to ensure that existing water quality conditions are accurately portrayed by the data and that the results do not reflect transitional conditions. The Department will consider a data set which does not meet this minimum requirement on a case-by-case basis to determine if the data adequately characterizes the water quality conditions. Summer-only sampling for nutrients, pathogenic quality, and temperature may be acceptable since summer generally represents the critical condition for these parameters. If the Department determines that the data set adequately represents water quality conditions and there are at least two exceedances of the Surface Water Quality Standards, this limited data set will be used to determine that a use is not attained. This methodology groups assessments as follows: Primary Contact Recreation (PCR) Indicators Aquatic Life Use Support (ALUS) Indicators Microbiological Assessment* Beach Closing Assessment* Toxicant Assessment (Human Health) Other Parameters Conventional Assessment* Toxicant Assessment (Aquatic Life) Toxicity Assessment Habitat Assessment Biological Assessment *These parameters were used in making the assessments used for listing during this reporting cycle. 2018 USVI Integrated Report Category 1 The assessment unit is placed in this category if it meets the water quality standards for the parameters that define support for both Primary Contact Recreation (PCR) & Aquatic Life Use Support (ALUS). Category 2 The assessment unit is placed in this category if it attains water quality standards for the parameters that define support for either PCR or ALUS but not all uses are supported. Category 3 The assessment unit is placed under the appropriate subcategory (3A, 3B, 3C, 3D) if insufficient or no data are available to determine if water quality standards are attained and any designated use is supported. Note: The Virgin Islands considers insufficient data as anything less than eight points of monitoring data. Waters with less than eight points of monitoring data may be reviewed on a case- by-case basis if the limited data strongly suggests that water quality standards are exceeded, and the designated uses are impaired. Such waters may be eligible for inclusion on the 303(d) List. This category contains four distinct subcategories: Category 3A No data are available from any of the identified data sources for the assessment unit in question. Category 3B Insufficient Data are available from any of the identified data sources for the assessment unit in question. Insufficient data is defined as less than eight points of monitoring data. This category differs from Category 2 in that this condition must apply to all designated uses. Category 3C Inconclusive Data are available from any of the identified data sources for the assessment unit in question. This might include information from studies that do not directly provide information related to water quality standards. Category 3D Unreliable or low-quality data is available from any of the identified data sources for the assessment unit in question. Unreliable or low-quality data is defined as data sets that have significant gaps, obvious anomalies, etc. Category 4 Assessment units that are found to be partially or not supporting for one or both designated uses are place in category 4 under the appropriate subcategory (4A, 4B, 4C), but does not require the development of a TMDL. This category contains three distinct subcategories: 2018 USVI Integrated Report Category 4A The assessment unit is placed in this category if it was previously listed on the 303(d) list and a TMDL has been established and approved by EPA. Category 4B The assessment unit is placed into this category only if other pollution control requirements are expected to address all water-pollutant combinations and attain all water quality standards within a reasonable period of time. The Virgin Islands considers a reasonable period of time as being the time between reporting cycles. If the impairment is the result of a point source discharge, it is expected that the Territorial Pollution Discharge Elimination System (TPDES) program will take appropriate measures to control point source pollution. If the impairment is the result of non-point source pollution, DPNR will provide evidence that a pollution control measure is in place. Category 4C The assessment unit is placed into this category if the impairment was not caused by a pollutant, but instead is caused by pollution. Assessment Units placed in Category 4C do not require the development of a TMDL. Pollution, as defined by the CWA is “the man-made or man-induced alteration of the chemical, physical, biological, and radiological integrity of water” (section 502(19)). In some cases, the pollution is caused by the presence of a pollutant and a TMDL is required. In other cases, pollution does not result from a pollutant and a TMDL is not required. These assessment units should be scheduled for monitoring to confirm that there continues to be no pollutant associated with the failure to meet the water quality standard and to support water quality management actions necessary to address the cause(s) of the impairment Category 5 The assessment unit is placed into this category if water quality standards are exceeded and a TMDL must be established.

if necessary, update the MYMS 2018 USVI Integrated Report Section 303(d) Waters Section 303(d) of the Clean Water Act requires States and Territories to develop a list of impaired waters needing TMDLs every even-numbered calendar year. An impaired waterbody is one for which technology-based pollution controls are not stringent enough to attain or maintain compliance with applicable State and Territory water quality standards. In order for a water quality-limited waterbody to attain water quality standards, a TMDL must be developed and implemented specifically for that waterbody and pollutant(s) of concern. A TMDL is a quantitative assessment of the amount of pollution that a certain waterbody can assimilate while still meeting water quality standards. On October 25, 2018, the Virgin Islands Department of Planning and Natural Resources released the 2018 303(d) List of Impaired Waterbodies for public comment. The final list consists of 80 assessment units listed for a variety of impairments. The 2018 303(d) List of Impaired Waterbodies is attached to this report as an Attachment. D. Estuary and Coastal Assessment 1. Designated Use Support Summary Assessment of the Virgin Islands’ coastal waters is presented in (estimated) square miles of assessment unit boundaries. Some 650 square miles are assessed in this report. A summary of use support assessments for coastal waters is shown in Table III.C.1.

Causes and Sources of Designated Use Impairment a) Eutrophication Eutrophication is rarely observed in the Virgin Islands because of tidal flushing and currents driven by the Caribbean current and steady Tradewind patterns. b) Case Studies The Unified Watershed Assessment includes a detailed summary of existing conditions for the 18 Coastal Zone Management Areas of Particular Concern. These APC reports contain water quality reports for each APC. E. Wetlands Assessment 1. Introduction Prior to October 31, 1978, the US Army Corps of Engineers, as delegated by 404 of the Clean Water Act, performed protection of wetlands in the Virgin Islands. After that date, all coastal wetland protection was mandated to the Department of Planning and Natural Resources, Division of Coastal Zone Management. Guidelines are found in 12 V.I.C. §903(b)(8) (2013), which states that the Division’s responsibility is “to conserve ecologically significant resource areas for their contribution to marine productivity and value as wildlife habitats, and preserve the function and integrity of reefs, marine meadows, salt ponds, mangroves and other significant areas”. 2. Classification of Wetlands Classification of wetlands is based on the US Fish and Wildlife Wetland and Deepwater Habitat System (Cowardin et al., 1979). Wetlands are grouped into four categories: tidal, seep, landlocked ponds, and spring tidal wetlands. Tidal ponds or lagoons have narrow inlets connecting to the sea and have a salinity level that is slightly higher than seawater. Seep ponds and landlocked ponds are not open to the sea and have fluctuating water and salinity levels depending on rainfall. Spring tidal wetlands fringe bays, but standing water only occurs during spring tides, when strong onshore winds push water into the wetlands, or during times of heavy rainfall and consequent flooding. The primary source of wetland impairment is non-point source pollution, construction intrusions, and sedimentation from upland run-off. 2018 USVI Integrated Report Table III.D.1 Wetlands Classification12 [Classification of wetlands is based on the US Fish and Wildlife Wetland and Deepwater Habitat System (Cowardin et al., 1979).] St. Croix Classification Great Pond Estuarine, Intertidal, Forested Billy French Pond Estuarine, Intertidal, Forested, Scrub-Shrub, Basin West End Salt Pond Estuarine, Intertidal, Unconsolidated sanded shore, Scrub-shrub, Basin Altoona Lagoon Estuarine, Intertidal, Forested Coakley Bay Marine (Coastal), Intertidal, Unconsolidated sanded shore Long Point Bay Estuarine, Unconsolidated sanded shore, Intertidal Mt.

Wetlands Protection Activities There is currently no Wetlands Management Program in the US Virgin Islands, though wetlands form a part of several programs and there are policies and legal mandates for management of wetlands. Wetlands are mentioned in the priority goals and objectives identified in the 2018 USVI Coral Reef Management Program, so some focus from the DPNR Division of CZM is increasing. Two of the four priority sites (St. Thomas East End Reserve and St. Croix East End Marine Park) include large areas of wetlands, and CZM, including its St. Croix East End Marine Park (EEMP) Program, has been including these wetland areas more and more in watershed management plans. However, the absence of policies and guidelines for wetlands management inhibit the development or integration of relevant programs. Even with policies to increase protections for wetlands approved by the Coastal Zone Management Commission in 2006, rules and regulations need to be promulgated and adopted within the coastal zone management program. Further, the single attempt to develop a wetlands conservation plan (Platenberg, 2006) focused on one district, and has not been approved or implemented. Lastly, there is no institutional arrangement that supports information sharing and collaborative programming, both necessary to ensure the development of synergies between the various programs. There is no clear picture of the current state of wetlands, particularly in terms of the environmental quality, species diversity and ecological integrity. That information gap results primarily from the absence of monitoring programs for wetlands or associated resources. The most extensive 2018 USVI Integrated Report information is generated by resource assessments (e.g. survey of water birds or survey of salt ponds) that tend to be island specific and decades apart. Researchers from the University of the Virgin Islands also conduct occasional site-specific assessments. F. Public Health/Aquatic Life Concerns Pollution-caused fish kills, ciguatera or other abnormalities The Department of Planning and Natural Resources keeps logs of fish kill incidents within the Territory when notified. For this reporting cycle, there was one reporting to DPNR of a Fish Kill, on August 17, 2017, caused by a discharge of raw sewage from a broken sewer force main adjacent to a freshwater pond. Approximately 240 fish were reported killed. The VI Waste Management Authority were required to fix and address the issues through enforcement action. Restrictions on swimming areas No sampling related to natural disasters (e.g. hurricanes or storms) was conducted this cycle. There were, however, the following natural disasters during this reporting cycle: FY16 No episodic monitoring conducted FY17 Hurricane Irma: September 6, 2017 - Conducted Beach/Coastal Assessments Hurricane Maria: September 19, 2017- Conducted Beach/Coastal Assessments (no conditional sampling done until FY18) The BEACH program issues notices on a weekly basis for territorial beaches that are being monitored. Advisories are issued following discovery of enterococci impairments. 2018 USVI Integrated Report IV. GROUNDWATER ASSESSMENT A. Virgin Islands Water and Power Authority (WAPA) The "major" water supplier in the VI is the Virgin Islands Water and Power Authority (WAPA). Ground water has the potential to contribute up to 30% (up to about 1 million gallons per day (MGD)) of the WAPA potable water supply on the island of St. Croix (when the well fields are operating at or near capacity). No ground water is used in the WAPA distribution system on St. Thomas and St. John at the present time; however, the authority has previously investigated the use of ground water in the Sugar Estate, St. Thomas and Estates Adrian and Carolina, St. John, to augment the desalinated water supply. WAPA : St. Croix On St. Croix, WAPA's principal water supply comes from desalination units, which are capable of producing about 3 MGD(storage capacity =40 MG). Additionally, WAPA can potentially extract up to 1 MGD of ground water from seven (7) well fields. The principal aquifer in St. Croix is the Kingshill aquifer, predominantly a limestone aquifer that underlies the central portion of the island. The Estates Concordia, Adventure, Fairplains, Negro Bay and Barren Spot well fields tap this aquifer. The western Mahogany Road and La Grange well fields tap an alluvial and fractured bedrock aquifer. 2018 USVI Integrated Report WAPA : St. Thomas On St. Thomas, WAPA provides desalinated water for distribution (approximately 2.2 MGD (storage capacity =40 MG)). Although WAPA used several wells in the vicinity of the St. Thomas Hospital in Sugar Estate from the late 1960s to the early 1980s, they are no longer used. As part of a recent ground water source exploration program designed for WAPA’s Emergency Ground Water Supply (EGWS) Program, the US Geological Survey (USGS) drilled several test wells in various locations on St. Thomas. USGS performed pumping tests on these wells in the Sugar Estate area, but to date, the wells have not been put into production. WAPA : St. John On St. John, WAPA’s principal potable water source is a 500,000 GPD vapor vacuum compression unit. Additionally, several wells were drilled on St. John under the EGWS program described above, but to date, with the exception of one well in Estate Carolina, the wells have not been put into production. The Estate Carolina WAPA well was put on line in the spring of 1994 as supplemental water supply for the eastern portion of St. John. The well provides mineral-rich water (TDS of approximately 2500 ppm) from a shallow, unconsolidated material aquifer, which is pumped into pressure tanks to meters for non-potable use only. 2. Public Water Systems that utilize groundwater In addition to WAPA, water-hauling companies utilize wells as a secondary water supply source. Several water-hauling companies treat the ground water by reverse osmosis (RO), and then distribute the water via trucks to individual residences and businesses. Several water-bottling companies also do the same prior to bottling and distribution. These public water systems also include apartment complexes, schools, condominiums, hotels, bars and restaurants. In addition to drinking water quality monitoring parameters, these systems must monitor their well water for Total Dissolved Solids.

Fresh water is an especially valuable resource in the VI. The meager but important ground water resources are valuable supplements to the expensive, highly energy-consumptive desalinated water which is so heavily relied upon by much of the population of the VI. Existing untainted ground water resources must be protected. The resources that have already been subjected to contamination by leaking underground storage tanks (USTs), leaking sewer lines and improper storage and disposal of 2018 USVI Integrated Report chemicals must be managed to protect adjacent uncontaminated sources and restore damaged resources for future use. B. Wellhead Protection Actualization Assessment The Territory does not at this time have a formal Wellhead Protection Plan (WHPP). There is a Wellhead Protection Final Report which was intended to form the nexus for a WHPP. It is anticipated that a WHPP be developed following the US EPA example ordinance3. The categories of permitted and non-permitted activities around wellheads4 contained in the model ordinance will be used. See Table , below for examples of the most common problems in St. Croix. Table IV.B.1 Non-Permitted uses in Zone 1 Automobile body/repair shop 1 Gas station 2 Fleet/trucking/bus terminal 3 Dry cleaner 4 Electrical/electronic manufacturing facility 5 Machine shop 6 Metal plating/finishing/fabricating facility 7 Chemical processing/storage facility 8 Wood preserving/treating facility 9 Junk/scrap/salvage yard 10 Mines/gravel pit 11 Irrigated nursery/greenhouse stock 12 Confined animal feeding operations 13 Land divisions resulting in high density (>1 unit/acre) septic systems 14 Equipment maintenance/fueling areas 15 Injection wells/dry wells/sumps, except for single-family residences directing gutter downspouts to a drywell 16 Underground storage tanks, (except those with spill, overfill, and corrosion protection requirements in place) 17 All other facilities involving the collection, handling, manufacture, use, storage, transfer or disposal of any solid or liquid material or waste having potentially harmful impact on groundwater quality including illegal disposal of solid waste on the surface not directly associated with a facility 18 3 The model is available at http://www.epa.gov/nps/ordinance/mol7.htm#groundwater. 4 Actually, in Zone 1, which for St. Croix is the 20-yr TOT radius. 2018 USVI Integrated Report Table IV.B.1 Non-Permitted uses in Zone 1 All uses not permitted in the underlying zone district 19 In Table IV.B.1, note that the sequential numbers are not intended as rankings; these numbers will be used to reference the specific threats in the database under development. 1. Time of Travel Buffers It is abundantly clear that essentially none of the existing priority wells, vendors, WAPA or large user, will meet any of the Time-of-Travel (TOT) suggested, either of the Model Ordinance, which uses 1,000 feet radius (as typical of a 6-month TOT) or in the calculations which are both more rigorous and locally calculated but give 20-yr TOT’s radii of approximately 1,400 feet or less with most around 1,000 feet. On the La Grange TOT the primary threats are the number of residences, all with on-site wastewater treatment as well as solid waste, industrial waste and stored or abandoned equipment. For Negro Bay wells, the primary threats are solid waste (informal dumps) and possible spills from the National Guard facility and the several warehousing facilities to the North. Negro Bay and New Golden Grove are probably the best-suited well fields on St. Croix from the standpoint of nearby risks; i.e., risks within the TOT wellhead protection area. 2. Flooding All of the WAPA and vendor production wells and many of the large users’ wells are located in flood hazard areas. Most WAPA wells are protected from inundation by reinforced concrete (RC) platforms and risers; an example is at Figure IV.C.10. These are typical of the wells inherited by WAPA from DPW and those developed by the Authority since. A much rarer WAPA well is at Figure IV.C.11 where the casing is continued to about 3’ above a platform but without the RC riser. This may be typical of wells developed by private owners and leased to WAPA. A number of vendors and smaller users near WAPA production wells are notably susceptible to flooding or entry of contaminants through inadequate siting or poorly sealed or unsealed well heads. Illustrations of these are at Figure IV.C.12 through Figure IV.C.10. 3. Particular threats – poor siting or construction There are a number of egregiously poor sites with wells; poor either because of sites selected and developed or because of poor or mismanagement of the wellhead area or areas adjacent. Since much of this development occurred before there was concerted effort to control development and manage wellhead impact areas there is little that can be done at this point. Some ideas are discussed below in the section - Suggestions for Interim Measures. Often, in the case of adjacent problems, the well owner or operator has little or no control over the use of that area. An example of poor siting is at Figure IV.C.16; this is a shallow well with a compromised seal and subject to overland flows that could include significant amounts of diesel and material from the road. 2018 USVI Integrated Report An example of poor site management (and a very poor well seal) is at Figure IV.C.20 and Figure IV.C.21. While the fuel tank might not exceed the minimum to require containment, it is directly adjacent to a well. In addition, the wellhead is very poorly sealed. Another example is at Figure IV.C.22 and Figure IV.C.23. Figure IV.C.23 is the cut-off well pipe and conduit for what was a production well at this site. This well is within 10 feet of a well in production for a water vendor and is, as may be seen, completely unprotected. 4. Summary The most common threat to wells and well recharge areas are the ubiquitous aggregations of household, construction and mechanical solid waste. However, it is apparent that the efforts of the Waste Management Authority have borne fruit; much of this material no longer occurs with the density nor is it as common as it was previously. Exceptions are piles of waste on private property (see Figure IV.C.24 and Figure IV.C.25). It is important to note that few of these threats to groundwater are the result of intentional misconduct or malfeasance. More typically, they are the result of a lack of understanding of the possible consequences of action or inaction. DPNR will schedule some community consciousness-raising meetings, utilizing some school time for students, for example. In addition, reminding landowners and agencies of responsible land management and the fragility of the groundwater resource in the Territory might also pay dividends. 5. Suggestions for Interim Measures The following suggestions assume that more staff time and effort will be available for implementing the permit program. While many wells had permits most have expired and many do not meet minimum requirements for permitting. For example, it is believed that most residential wells do not have meters and many commercial wells also do not have meters – or functioning meters – and reporting and permit renovation is not done. In addition, there are a number of large production wells that are not and have never been permitted. i. Educate Licensed well drillers DPNR-DEP issues well drillers licenses. DPNR-DEP will use the opportunity to focus educational efforts on the single entity (well drillers) that would touch every new well. If permitted well drillers were responsible for acquiring permits for wells a body of knowledgeable persons would be dealing with DPNR-DEP in the siting and development of new wells. ii. Individual existing wells At least some effort should be made to assist owners and operators of production wells to reduce threats in the areas of their wellheads. The adoption of a wellhead protection plan should help resolve this, but in the interim assistance in the form of consumer education and assistance with enforcement of Territorial regulations on unpermitted solid waste sites, illegal dumping and storage and handling of liquids, toxic and hazardous materials could provide some relief for owners of wells subject to surface and sub-surface threats. 2018 USVI Integrated Report iii. Relief for owners of permitted wells The Territory should begin to ensure that all permits are current and that permit holders understand their responsibilities in ensuring the viability of groundwater resources in USVI. As part of this effort DPNR-DEP could provide assistance with cataloguing specific threats to permitted wells and provide permittees with an understanding of the possible effects of those threats to their water quality and a record of the then-current state at the time of renovation. In addition, DPNR-DEP could provide permittees with measures they can undertake to eliminate, reduce or manage those risks. As an incentive to renovating permits DPNR-DEP could provide well owner/permittees a specific time period to deal with threats under their control with no penalties. C. WAPA wells 1. WAPA wells to remain in service The WAPA wells that are to remain in service are shown at Table, below. WAPA has not used any groundwater since about April of 2010 since the RO unit at Richmond came on-line. The wells to be retained will be secured and stand-by power will be provided. As part of the work in this project the possibility of distributing normal power from a central location, probably the Fairplains Pump Station, will be considered and reported. This will ease the provision of stand-by power since a single large generator located at or near the central location could be provided and power distributed using the same network used for normal power. Individual costs are not provided at this time, though approximate costs will be part of the final report following consultations with WAPA on the form and generality of security and service-assurance techniques. All these wells use the Fair Plains pump station. Table IV.C.1 Primary WAPA Wells Well#5 Well Name GPM SWL6 Depth 9 Bethlehem 40 38.1 114.2 10 Bethlehem 40 27.6 121.3 5A Negro Bay 10 52.7 110.5 5 Negro Bay 25 59.3 114.9 6 Negro Bay 20 65.3 130.1 7 Negro Bay 35 58.6 115.1 6 New Golden Grove 35 59.3 114.9 7 New Golden Grove 35 63.3 130.1 8 New Golden Grove 37 52.7 110.5 15A New Golden Grove 40 62.1 122.5 5 These numbers will be standardized; at least two methods are currently in use. 6 Standing Water Level. 2018 USVI Integrated Report Output of these wells, as reported by WAPA in 2010, sums to about 0.5 MGD (24-hr day, or 0.25/12 hr day). It remains to be seen if these will improve with reduced WAPA usage. DPNR-DEP has recommended placing well-level meters in at least one well in Negro Bay and one in New Golden Grove. Historical data for static water levels[3] in St. Croix are shown at Figure IV.C. and Figure IV.C.. As may be seen Negro Bay and New Golden Grove show the best levels. Half a million gallons per day would approximate around 20-25% of normal production. In the event that these wells would become the sole source in the event of a weather or geologic event interrupting normal service WAPA and St. Croix could probably maintain minimal service for several weeks. The risk of such an event and the value of additional emergency production must be considered. WAPA Wells not now scheduled for service beyond 2010 These are shown in Table IV.C.2. These are mostly wells that were developed and owned by others and WAPA has or will let leaseholds lapse. Owners will be advised that these wells must either be permitted and comply with construction and protection norms or abandoned and closed properly. WAPA-owned wells will be subject to the same requirements.

Those that have reverted to private hands will be noted and DPNR will schedule dates for closing or rehabilitation, sanitary seal acceptability and security. A priority schedule will be developed. 2018 USVI Integrated Report Table IV.C.3 WAPA Well Fields not intended for service after 2010 Field Name Number of Wells/ Prosperity Name used for La Grange and Mahogany Road wells at one time Mahogany Road 4 All require proper closure or improved protection and seals if owner wants to continue use.

Concordia 5 Wells selected by the amount of water pumped. The amount of pumpage is generally uncertain and our cut-off is 6,000 gallons per day (gpd, ~2MG per year). The first priority for these wells will be to verify the production numbers. It is known that a number of these wells belong in the high-risk category, in addition. For example, several of these wells are known to be located in parking lots though they are not precisely located. In general, these have the same threats as do the WAPA wells, with the added problem that they can be very near unsewered population centers. Wells prioritized by risk. Risk is used as an analog for the population served or affected by this source and is estimated by: a. Type of purveyor i. Water Source (vendors, standpipe) ii. Bottled Water vendor or source iii. Condominiums iv. Apts v. Hotels b. Population served i. Total for Condos, Apts and Hotels ii. NT for others There are a total of approximately 60 wells in addition to the WAPA wells, or about 140 wells in all. These are listed in Table IV.C.5. 2018 USVI Integrated Report Figure IV.C.10.

September 30, 2009. 2018 USVI Integrated Report Appendix 1: 2018 303(d) List Narrative 2018 USVI Integrated Report 2018 U.S. Virgin Islands 303(d) List of Impaired Waters January 2019 Prepared by: Benjamin Keularts Environmental Program Manager Department of Planning & Natural Resources Division of Environmental Protection 45 Mars Hill Frederiksted, VI 00841 2018 USVI Integrated Report I. SUMMARY Section 303(d) of the Clean Water Act requires States and Territories to develop a list of impaired waters (requiring Total Maximum Daily Loads, TMDLs) every even-numbered calendar year. An impaired waterbody is one for which technology-based pollution controls are not stringent enough to attain or maintain compliance with applicable State and Territory water quality standards. In order for a water quality-limited waterbody to attain water quality standards, a TMDL or other approved alternative management or protection plan must be developed and implemented specifically for that waterbody and/or pollutant(s) combination of concern. A TMDL is a quantitative assessment of the amount of pollution that a certain waterbody can assimilate while still meeting water quality standards. EPA regulations require States and Territories to: • Identify water quality limited waters still requiring TMDLs after the implementation of technology-based or other pollution controls. • Establish a priority ranking of these waters. • Identify pollutants causing impairment. • Identify waters targeted for TMDL development over the next two (2) years. II. LIST DEVELOPMENT This 2018 submission, required under Section 303(d)(1)(A) of the Clean Water Act, requires submission of a biennial list of water quality-limited waters. This list identifies waters that are not supporting designated uses because they do not meet surface water quality standards despite the implementation of technology-based effluent limits. The complete list of data sources used to develop the USVI 2018 Section 303(d) list is as follows: • U.S. Virgin Islands Ambient Monitoring data from Fiscal Years 2015-2017 (VI Department of Planning & Natural Resources, VIDPNR) • U.S. Virgin Islands BEACH Monitoring data from Fiscal Years 2015-2017 (VIDPNR) • 2016 U.S. Virgin Islands Section 305(b) Report (VIDPNR) 2016 303(d) List (VIDPNR) The above list of data represents all existing and readily available data for the 2018 submission. These data are limited, and many waters have been listed based on a suspected impairment. 2018 USVI Integrated Report On November 2, 2015, the Division of Environmental Protection (DEP) began its data solicitation notice process announcing that data would be accepted until December 2, 2015. Additionally, letters were sent to the following agencies to request relative data: Environmental Protection Agency (EPA) Region 2; US Fish & Wildlife Service; National Park Service; University of Virgin Islands-Cooperative Extension Service and Center of Marine and Environmental Services; National Marine Fisheries Service; US Geological Survey and National Oceanic and Atmospheric Administration-National Undersea Research Program and Coral Reef Conservation Program; VI Department of Health; US Department of Agriculture; The Nature Conservancy. There were no responses to submit relevant data. III. DATA NOT USED From the complete list of data sources used to develop the USVI 2018 Section 303(d) list as noted above in Section II, several data sets were not used. Those data sets, and reasons they were not used, are as follows: • NOAA Data submitted through Data Solicitation: DPNR received only one set of data from outside agencies during the data solicitation period noted above; however, that data could not be used as it was from interstitial water samples, and DPNR does not currently have classifications for, water quality criteria for, or assess interstitial waters. • Fecal coliform datasets (all historical data): As the fecal coliform criteria were replaced by enterococci bacteria criteria in the 2015 USVI Water Quality Standards, all historical fecal coliform data are no longer applicable. As such, the DEP has chosen to discard this data from the dataset and have removed all impairments for this parameter. The DEP has assessed that the bacteria data now collected will be an appropriate substitute for the fecal coliform parameter and therefore this change will meet the Antidegradation requirements detailed in the VI WQS. The delisting of waterbodies for this parameter is considered necessary to ensure that the parameter will not stay on the 303(d) list of impaired waterbodies in perpetuity, without the opportunity for de-listing. There were 23 Assessment Units (AUs) which were delisted for fecal coliform since the water quality standard is no longer applicable: Assessment Unit (AU) Assessment Unit Name VI-STC-16 Salt River Lagoon, Marina VI-STC-18 Salt River Bay VI-STC-27 Long Reef Forereef, East VI-STC-29 Christiansted Harbor, East VI-STC-30 Beauregard Bay VI-STC-31 Buccaneer Beach 2018 USVI Integrated Report Assessment Unit (AU) Assessment Unit Name VI-STC-35 Tamarind Reef Lagoon (Southgate Lagoon) VI-STC-37 Southgate Subwatershed, Offshore VI-STC-39 Teague Bay VI-STC-40 Teague Bay Backreef VI-STC-47 Turner Hole Backreef VI-STC-52 Great Pond Bay VI-STC-56 Bugby Hole Backreef VI-STC-62 Limetree Bay VI-STC-64 Manning Bay/Estate Anguilla Beach VI-STC-65 HOVENSA West VI-STJ-25 Rendezvous Bay VI-STJ-30 Cruz Bay VI-STT-13 Mandahl Bay (Marina) VI-STT-17 Mandahl Bay Subwatershed, Offshore VI-STT-23 Vessup Bay VI-STT-32 Jersey Bay, Offshore VI-STT-35 Mangrove Lagoon Another two (2) AUs were delisted for fecal coliform as there is now a TMDL in place (VI-STC-26 Christiansted Harbor and VI-STT-34 Benner Bay Lagoon Marina) and one (1) that was delisted as it was placed in ATTAINS by error: VI- STT-26 Red Hook Bay, offshore (the approved 2016 303(d) list did not include it). • pH data taken from AUs in the St. Thomas / St. John District on 6/14/2016, 9/27/2016, and 12/13/2016: This dataset was not used as the samplers noted that the pH values were suspect and there was some drift in the midday calibration of the sampling equipment. As a result, DPNR is not confident in the accuracy of the data or the representativeness of the water quality conditions. The nine (9) AUs which would have otherwise been delisted this cycle for pH will remain on the list of impaired waters. • pH data taken from AUs in the St. Croix District on 6/14/2016, 9/27/2016, and 12/13/2016: Despite St. Croix samplers making no comment on the suspect quality of the water quality data, DEP noted on review that the vast majority of pH readings exceeded the high range of the standard, however, over the same period in St. Thomas and St. John, there were very few samples which exceeded the standard. As such, DEP has categorized waterbodies with the high pH data as Category 3, rather than Category 5 in 2018. 2018 USVI Integrated Report IV.

LISTING ACTION The EPA released a guidance memorandum for developing the 2018 Integrated Water Quality Monitoring and Assessment Report that serves to supplement all previously- issued assessment guidance issued in 2006, 2008, 2010, 2012, 2014 and 2016. Waterbody assessment units are classified into one of five categories. Below are the categories DPNR used for 2018 assessments: Category 1 The assessment unit is placed in this category if it meets the water quality standards for the parameters that define support for both Primary Contact Recreation (PCR) & Aquatic Life Use Support (ALUS). 2018 USVI Integrated Report Category 2 The assessment unit is placed in this category if it attains water quality standards for the parameters that define support for either PCR or ALUS but not all uses are supported. Category 3 The assessment unit is placed under the appropriate subcategory (3A, 3B, 3C, 3D) if insufficient or no data are available to determine if water quality standards are attained and any designated use is supported. Note: The Virgin Islands considers insufficient data as anything less than eight points of monitoring data. Waters with less than eight points of monitoring data may be reviewed on a case-by-case basis if the limited data strongly suggests that water quality standards are exceeded, and the designated uses are impaired. Such waters may be eligible for inclusion on the 303(d) List. This category contains four distinct subcategories: Category 3A No data are available from any of the identified data sources for the assessment unit in question. Category 3B Insufficient Data are available from any of the identified data sources for the assessment unit in question. Insufficient data is defined as less than eight points of monitoring data. This category differs from Category 2 in that this condition must apply to all designated uses. Category 3C Inconclusive Data are available from any of the identified data sources for the assessment unit in question. This might include information from studies that do not directly provide information related to water quality standards. Category 3D Unreliable or low-quality data is available from any of the identified data sources for the assessment unit in question. Unreliable or low-quality data is defined as data sets that have significant gaps, obvious anomalies, etc. Category 4 Assessment units that are found to be partially or not supporting for one or both designated uses are place in category 4 under the appropriate subcategory (4A, 4B, 4C), but does not require the development of a TMDL. This category contains three distinct subcategories: Category 4A The assessment unit is placed in this category if it was previously listed on the 303(d) list and a TMDL has been established and approved by EPA. 2018 USVI Integrated Report Category 4B The assessment unit is placed into this category only if other pollution control requirements are expected to address all water-pollutant combinations and attain all water quality standards within a reasonable period of time. The Virgin Islands considers a reasonable period of time as being the time between reporting cycles. If the impairment is the result of a point source discharge, it is expected that the Territorial Pollution Discharge Elimination System (TPDES) program will take appropriate measures to control point source pollution. If the impairment is the result of non-point source pollution, DPNR will provide evidence that a pollution control measure is in place. Category 4C The assessment unit is placed into this category if the impairment was not caused by a pollutant, but instead is caused by pollution. Assessment Units placed in Category 4C do not require the development of a TMDL. Pollution, as defined by the CWA is “the man-made or man-induced alteration of the chemical, physical, biological, and radiological integrity of water” (section 502(19)). In some cases, the pollution is caused by the presence of a pollutant and a TMDL is required. In other cases, pollution does not result from a pollutant and a TMDL is not required. These assessment units should be scheduled for monitoring to confirm that there continues to be no pollutant associated with the failure to meet the water quality standard and to support water quality management actions necessary to address the cause(s) of the impairment Category 5 The assessment unit is placed into this category if water quality standards are exceeded and a TMDL must be established. Assessment units that are placed into Category 5 will be placed on the 2018 303(d) List. VII. WATERBODY DELINEATION The US Virgin Islands has created a standard waterbody delineation that organizes the coastal waters of the Virgin Islands into assessment units. This delineation is based on (in order of consideration): 1. Legal limits of water quality classifications 2. Subwatershed boundaries 3. Shoreline geomorphology 4. Benthic geomorphology 5. Bathymetry 6. Benthic habitats 7. 305(d) listing and TMDLs 8. Management areas 9. 305(b) assessment 2018 USVI Integrated Report In the 2018 Integrated Report, these delineated assessment units have been grouped into categories. No assessment unit boundaries have changed since the 2016 assessment. VIII.

Introduction The Clean Water Act requires States and Territories to conduct water quality surveys to determine if its waters are healthy and are of sufficient quality to meet their designated uses and attain water quality standards. Water quality data for individual Assessment Units (AU) from internal sources (that is, the Department of Planning & Natural Resources, DPNR) and external sources are evaluated and, if water quality standards are exceeded and designated uses are not being attained, the AU will be placed on the 2018 303(d) Impaired Waterbody List. States and Territories are required to submit the methods used to collect, analyze, and interpret data to determine compliance with applicable water quality standards and assess support of the applicable designated uses in an Assessment Methodology Document for USEPA and public review. The DPNR Division of Environmental Protection (DEP) has prepared this report to summarize and respond to the comments received on the public noticed draft of the 2018 303(d) Impaired Waterbody List associated Assessment Methodology Document. No public hearings were held; however, written comments were received from the US EPA and one organization (the Coral Bay Community Council, CBCC) during the 60- day public notice period. The public comment period began on July 31, 2018 and ended on October 4, 2018. The public notice for hearing was published in The Daily News. II. Comments During the public comment period, DPNR received comments via email on the 2018 Assessment Methodology Document from the US Environmental Protection Agency (EPA) on November 14, 2018, and from Coral Bay Community Council (CBCC) on November 23, 2018. Below is a summary of the comments received by DPNR from EPA and CBCC, and DPNR’s responses to those comments. Please note that while the comments received resulted in changes to the 2018 Assessment Methodology document, no significant changes were made that would require another public notice or hearing. 2018 USVI Integrated Report Public Comments received on the 2018 Assessment Methodology Document via email: 1. Rachel McKinley (on behalf of CBCC): Page 5: Class “A” Waters, Designated Uses: Modified “…Under Water Trail at Trunk Bay…” to “Underwater Trail at Trunk Bay…”. VIDPNR agrees with the commenter and has amended the sentence as suggested. 2. Rachel McKinley (on behalf of CBCC): Page 13: Class B unmonitored waters (57): Highlighted the following: • VI-STJ-07 Maho Bay subwatershed, offshore • VI-STJ-08 Mary Point • VI-STJ-14 Hurricane Hole • VI-STJ-18 Grootpman Bay • VI-STJ-27 Rendezvous Bay subwatershed, offshore The highlighted sights- are the[y] NPS waters? VIDPNR notes that VI-STJ-14 Hurricane Hole and VI-STJ-27 Rendezvous Bay subwatershed, offshore are not part of the Virgin Islands NP. However, the Virgin Islands NP does incorporate VI-STJ-07 Maho Bay subwatershed, offshore, VI-STJ-08 Mary Point and VI-STJ-18 Grootman Bay. The section being referred to “Unmonitored Waters” refers to waters not currently monitored through DPNR-DEPs Ambient Monitoring Program (or any other internal programs). Therefore, even though NPS may monitor the above three waters, they are classed as “unmonitored waters” for DPNR- DEPs purposes since there are no DEP monitoring stations located within these assessment units. DPNR-DEP has no control over whether NPS provide data, collect data in accordance with DPNRs QA/QC protocols or in a quantity sufficient to assess the waters. Therefore, it is the ongoing goal of DEP to internally assess and characterize the condition of all waters in the United States Virgin Islands and to eventually include monitoring stations within these assessment units. 2018 USVI Integrated Report 3. Rachel McKinley (on behalf of CBCC): Page 13: Class B unmonitored waters (57): [In reference to VI-STJ- 18 Grootpman Bay] Did you mean Grootpan Bay? VIDPNR agrees with the commenter and has corrected the spelling error to “Grootpan Bay”, as suggested. 4. Rachel McKinley (on behalf of CBCC): Page 13: Class B unmonitored waters (57): Various spelling corrections VIDPNR agrees with the commenter and has corrected the spelling of “subwatershed”, “Rendezvous Bay” and “Judith’s Fancy” 5. Sharon Coldren (on behalf of CBCC): Page 14 and 15, Figures and 10 & 11: The diagram looks like all areas, not differentiated? Am I misreading labels? VIDPNR agrees with the commenter and has corrected the Figure descriptions on page 14 & 15 to “All Assessment Units, including monitored waters, unmonitored waters, and monitored but not assessed waters” rather than “Currently unmonitored waters, and monitored but not assessed waters” 6. Helen Grebe (on behalf of US EPA): Page 16 list[s] 83 near-shore sites from St Croix. I believe this is a typo and should be 55. VIDPNR agrees with the commenter and has corrected the error on page 16 to “55 near-shore sites from St Croix.” 7. Rachel McKinley (on behalf of CBCC): Page 18: [In reference to basing coral reef ecosystems on the Benthic Habitat Atlas of Puerto Rico and the U.S. Virgin Islands (2002)] Is there an updated set? Lidar data? VIDPNR notes that there is currently no updated Benthic Habitat Atlas for the US Virgin Islands. 2018 USVI Integrated Report 8. Sharon Coldren (on behalf of CBCC): Page 18, Section 3.1.2 DPNR Monitoring Sites in Areas that contain coral reef ecosystems As I look at the maps from this #22 & 23 attached – it seems clear to me that some of the coral bay monitoring points are in or directly adjacent to reef ecosystems from this source… For the purpose of the 2018 Assessment Methodology, DPNR determines that was constitutes coral reef ecosystems would be equivalent to the following 2002 NOAA Benthic Habitat Maps polygons only: Reef/Linear Reef, Reef/Spur and Groove Reef and Reef/Patch Reef. Therefore, some sites may be near coral reef habitat, but not necessarily within coral reef ecosystems. Nonetheless a reassessment of site locations was made and it was in fact determined that two more sites were considered to be in coral reef ecosystems: STT-14 & STJ-57. A reassessment of the data was conducted but using the more stringent criteria resulted in no change to the AUs in which these sites were located, and no change to the draft 303(d) list. 9. Rachel McKinley (on behalf of CBCC): Page 18, Section 3.1.3 Evaluation of External Data: CBCC also submitted data during this time, although was not in relations to the monitoring site- inland data. Only Assessment Units in Marine and Coastal Waters were included on the 2018 303(d) List. There is currently no comprehensive Inland Water Quality Monitoring Program within the VI, and there is limited Standards for Inland Water Quality. Therefore, external monitoring data for assessing inland waters will not be evaluated until they are supplemented by data collected internally by DEP. 10. Rachel McKinley (on behalf of CBCC): Page 19, Section 3.3 Visual Data Sources: [In reference to there being no visual data sources or logged incidents]: What about the sargassum? VIDPNR notes that visual data from Sargassum would be a useful addition. However, the inclusion of visual observations for Sargassum was only added specifically to the Beach Monitoring Program in September 2018. Therefore, any intermittent data on the presence of sargassum would be considered incomplete. VIDPNR intends to include this data in the 2020 303(d) list, since the WQRS state the need for waters to be free from “Matter - floating debris, … and other nuisance matter.” 2018 USVI Integrated Report 11. Rachel McKinley (on behalf of CBCC): Page 19, Section 3.3 Visual Data Sources: [In reference to there being no visual data sources or logged incidents]: No spills from the storms? What about all the boats with gas?? There was no specific post-storm monitoring of oil, grease and other marine fluid spills conducted throughout the Territorial waters by DPNR-DEP or reported to DEP. However, in response to this comment, DEP performed a review of the Beach Water Quality Monitoring Program Field Sheets and the Ambient Monitoring Program Field Sheets following the September 2017 storms and no oil sheen was noted on any of the field observation sheets. Field Teams are trained to document such spills if they are observed. However, it is possible that any such spills had dissipated by the time the quarterly Ambient sampling was conducted. 12. Rachel McKinley (on behalf of CBCC): Page 20, Section 3.6 Natural Disasters Edited: “However, the following storm events occurred…” to “However, the following storm and associated sampling events occurred…” VIDPNR agrees with the commenter and has amended the sentence as suggested. 13. Rachel McKinley (on behalf of CBCC): Page 21, Section 3.7 QA/QC: Add a link or appendix to the SOPs & QAPPs. VIDPNR agrees with the commenter and shall add a link to the SOPs and QAPPs upon finalization of the current drafts. 14. Sharon Coldren (on behalf of CBCC): Page 27, Section 4.2.3 Habitat Assessment: [In regard to the work group to discuss correlations between water quality and various indicators] CBCC would like to be linked in to this group, for identifying and monitoring species in Coral Bay, as we do somewhat routinely with volunteers. VIDPNR agrees with the commenter that CBCC can provide useful contribution to such a workgroup and shall include CBCC on further progress with this workgroup. 2018 USVI Integrated Report 15. Sharon Coldren (on behalf of CBCC): Page 27, Section 4.2.4 Biological Assessment: [In regard to obtaining biological data to be evaluated against the narrative Biocriteria outlined in the VI Water Quality Standards] We would like to know how to do this, and probably could do it, in cooperation with FWS and others, and get a grant for it. VIDPNR agrees with the commenter that there is a need to diversify the Agencies which provide biological data to be assessed against paired water quality conditions. VIDPNR is a part of the BCG Workgroup. The Workgroup is creating a Biological Condition Gradient (BCG) model which will allow changes in biological community structure and function (e.g. species abundance, rugosity, biomass etc.) to be correlated to Water Quality Standards. Once this Model has been finalized, VIDPNR will share with CBCC to ascertain whether it is something that could be implemented. 16. Rachel McKinley (on behalf of CBCC): Page 36, Attachment A: [In regard to the list of agencies which were contacted to request data during the Data Solicitation Period] Why no response or submitted data? Agencies are given 30 days to provide VIDPNR with relevant monitoring data for the monitoring period with the associated Quality Assurance Project Plan. DPNR public noticed a Data Solicitation request on January 25, 2018, which ended on February 24, 2018. However, there was an omission from the original Attachment A. DPNR did receive data from NOAA related to the study: Phase 1 Porewater Toxicity Testing of Sediment from 25 Near- Shore sites in St. Croix, USVI, done by Lisa A. May and Cheryl M. Woodley (NOS NCCOS CCEHBR & HML, CRCP Project 1133, November 2016). This has been added to the AM document. 17. Sharon Coldren (on behalf of CBCC): General Comment (emailed): Seeing phosphorus and dissolved oxygen issues make me wonder about wastewater treatment issues and subterranean groundwater contamination of the ocean – more than just surface flows and land development issues. Is there a label for these type of concerns in the assessment methodology? The scope of the assessment methodology document does not include labeling, grouping or expanding on specific sources of pollution, except to determine if they are anthropogenic or not (in order to determine if an exceedance is natural or not). The purpose of the AM document is primarily to determine if there is an impairment, not what the cause of it is. 2018 USVI Integrated Report Appendix 4: 2018 Responsiveness Summary for US Virgin Islands 303(d) List of Impaired Waters 2018 USVI Integrated Report Responsiveness Summary 2018 US Virgin Islands 303(d) List of Impaired Waters April 2019 Prepared By: Department of Planning & Natural Resources Division of Environmental Protection 2018 USVI Integrated Report III. Introduction The Clean Water Act requires States and Territories to conduct water quality surveys to determine if its waters are healthy and are of sufficient quality to meet their designated uses and attain water quality standards. Water quality data for individual Assessment Units (AU) from internal sources (that is, the Department of Planning & Natural Resources, DPNR) and external sources are evaluated and, if water quality standards are exceeded and designated uses are not being attained, the AU will be placed on the 2018 303(d) Impaired Waterbody List. The DPNR Division of Environmental Protection (DEP) has prepared this report to summarize and respond to the comments received on the public noticed draft of the 2018 303(d) Impaired Waterbody List. No public hearings were held; however, written comments were received from the US EPA and one organization (the Coral Bay Community Council, CBCC) during the 60-day public notice period. The public comment period began on July 31, 2018 and ended on October 4, 2018. The public notice for hearing was published in The Daily News. IV. Comments During the public comment period, DPNR received comments via email on the 2018 303(d) List of Impaired Waters from the US Environmental Protection Agency (EPA) on November 14, 2018, and from Coral Bay Community Council (CBCC) on November 23, 2018. Below is a summary of the comments received by DPNR from EPA and CBCC, and DPNR’s responses to those comments. No changes were made to the 303(d) list of Impaired Waters as a result of the public comment period. 2018 USVI Integrated Report Public Comments received on the 2018 303(d) List of Impaired Waters via email: Number Comment Response 1. Helen Grebe (on behalf of US EPA): I do not see station STC33 on the 303d list. I have reviewed the 2017 dissolved oxygen and turbidity data for this station and have found exceedances. Is this an oversite? Or do these exceedances not meet the criteria for listing? VIDPNR agrees with the commenter that there are 9 exceedances for STC-33 for Dissolved Oxygen (DO). However, given that there is an existing TMDL for Salt River for DO, the AU will not be included on the 303(d) list as well. In addition, VIDPNR notes that while there are exceedances of turbidity, the criteria for listing have not been met, since the Marina is one of the Class B waters that has a Turbidity exemption in the VI Water Quality Standards (VIWQS), based on §186-11 (Natural Conditions). Therefore, despite turbidity values exceeding the limit for Class B Waters, the AU will not be listed for turbidity (however, please note that clarity criteria still apply). 2. Helen Grebe (on behalf of US EPA): The 303d list has a tentative year of TMDL completion. In addition, I recommend developing a tentative year to begin development of the TMDL. VIDPNR agrees with the commenter and will include a tentative year to begin development of the TMDL in the 2020 list, to improve TMDL planning and ensure timeframes are adhered to. 3. Helen Grebe (on behalf of US EPA): The 303d list sets a priority of high, medium or low. The methodology document does not document how this is determined. I recommend developing a formal process to set the priority. The process does not have to be complex, maybe a weighted checklist with a few questions. For example, each water body would get more points if it was previously listed, more points if it’s in a sensitive area, more points if it exceeded more than one WQS, more points if it consistently exceeded the WQS, and so on. VIDPR agrees with the commenter that a standardized, transparent and objective process should be in place to determine the priority rankings for TMDL development. Currently, there is an informal procedure, but it is the aim of VIDPNR to formalize and document this process prior to the issuance of the 2020 303(d) list. 2018 USVI Integrated Report 4. Sharon Coldren (on behalf of CBCC): I took a few moments to refresh myself on the 2016 303d list. From before your time on this, we have had some errors in GPS/map positioning of the data collection points – and thus the AU units that you assess. Previous corrections are included here, although I do have a couple of questions or areas I am confused about. I think that STJ 55 and NPS 26 Turner Bay is in Coral Bay (not in Enighed Pond – where it is listed in the 2016 303d list. P. 217). I might be wrong, but – just the # tells you it’s on the eastern side of STJ. It is the outcropping of the Hurricane Hole bay – so may be in National Park waters (monument) waters. Although there were errors in the GPS positioning of certain points, STJ-55 is listed correctly as being in Turner Bay on the west side of St. John. The commenter is correct that most sites numbered similarly to STJ-55 (e.g. STJ-52, -53, -56-, 57- and -58) are located on the east side of St. John in the Coral Bay/East End area, however, due to historic numbering, STJ- 55 is not. 5. Sharon Coldren (on behalf of CBCC): I was surprised to see that no STJ AUs were deemed to be coral reef ecosystems. I have attached two maps from the 2002 benthic habitat report you reference that seem to show these in STJ to my eye. And we have more patch reef than these show. For the purpose of the 2018 Assessment Methodology, DPNR determines that what constitutes coral reef ecosystems would be equivalent to the following 2002 NOAA Benthic Habitat Maps polygons only: Reef/Linear Reef, Reef/Spur and Groove Reef and Reef/Patch Reef. Therefore, some sites may be near coral reef habitat, but not necessarily within coral reef ecosystems. Nonetheless a reassessment of site locations was made and it was in fact determined that two more sites were considered to be in coral reef ecosystems: STT-14 & STJ-57. A reassessment of the data was conducted but using the more stringent criteria resulted in no change to the AUs in which these sites were located, and no change to the draft 303(d) list.
