No. 0 PART II: WASTE SOURCE INFORMATION For each of the waste units identified in Part I, complete the following six items. Waste Unit 1 Drums Waste Oil Drums 1. Identify the RCRA status and permit history, if applicable, and the age of the waste unit. There are no known current or previous RCRA permits for the Ramsey Motors Site. The age of the waste unit is unknown. The Water and Power Authority (WAPA) stopped accepting waste oil, which it used for fuel, in 1986 when it was found to contain PCBs. Since that time nearly all waste oil on St. Thomas has been stored, as there is no acceptable method of disposal. 2. Describe the location of the waste unit and identify clearly on the site map. The waste unit is located inside an overhang garage in the northeast corner of the Ramsey Motors property. 3. Identify the size or quantity of the waste unit (e.g., area or volume of a landfill or surface impoundment, number and capacity of drums or tanks). Specify the quantity of hazardous substances in the waste unit. 4. Twenty-five 55-gallon drums of waste oil are stored along the inside perimeter of an automotive repair garage. Identify the physical state(s) of the waste type(s) as disposed of in the waste unit. The physical state(s) should be categorized as follows: solid, powder or fines. sludge. slurry. liquid, or gas. The drums on site contain automotive waste oil, which is a liquid. 5. Identify specific hazardous substance(s) known or suspected to be present in the waste unit. The waste units contain automotive waste oil. Readings ranging from 10 to 90 ppm and 60 to 300 ppm were detected on the HNu photoionization detector and OVA flame ionization detector, respectively, in open drums in the garage. Substances such as gasoline, kerosene, and degreasing solvents may also be present in the drums. 6. Describe the containment of the waste unit as it relates to contaminant migration via groundwater, surface water, and air. The waste oil drums are located inside a garage on a cement floor. Some of the drums were open, and there were spills on the floor of the garage. Small quantities of oil apppeared to be leaking out of the garage onto the soil. Ref. Nos. 1 20 21 - 02-8902-42-PA Rev. No. 0 PART Ill: HAZARD ASSESSMENT GROUNDWATER ROUTE 1. Describe the likelihood of a release of contaminant(s) to the groundwater as follows: observed, alleged, potential, or none. Identify the contaminant(s) detected or suspected, and provide a rationale for attributing the contaminant(s) to the facility. 2. The likelihood of a release of contaminants to the groundwater from the waste unit on site is small. Although some of the drums were not properly closed, all the drums were stored inside on a cement floor. There are no berms or curbs to contain the waste in the event of a spill. The drums contain automotive waste oil. Air monitoring instrument readings inside the drums ranged from 10 to 300 ppm. This suggested that the drums may contain volatile components, possibly gasoline, kerosene, or degreasing solvents. These substances are typically associated with automotive facilities. Ref. No. 1 Describe the aquifer of concern; include information such as depth, thickness, geologic composition, permeability, overlying strata, confining layers, interconnections, discontinuities, depth to water table, groundwater flow direction. The rock units of St. Thomas and St. John are divided into three major groups. The Water Island Formation, which is late lower Cretaceous in age, consists of keratophyre and spillates. The Virgin Island Group, which is probably early Cretaceous or Albian in age, consists of andesitic-pyroclastic rocks and sedimentary formations. The Virgin Island Group is divided into four formations: The Louisenhoj Formation, which consists of augite-andesite breccia, tuff, and conglomerate; the Outer Brass Limestone which consists of partially silicified- tuffaceous-radiolarian-limestone; the Tutu Formation, which consists of tuffaceous wacke, including megabreccia near the base and limestone near the top; the Hans Lollik Formation which may be Eocene in age consists of augite-andesite breccia and tuff. The final group is made up of one or more dioritic plutons. These unamed dikes and plugs of quartz - andesine hornblende - porphory are Upper Cretaceous and Lower Tertiary in age. Alluvian deposits are quarternary in age. The Water Island Formation which consists of 95 percent volcanic flow breccias was probably extruded on a relatively level ocean floor. The absence of terrigenous sediments from this formation indicates that there were no emergent islands present in the area at the time of extrusion. Emergent islands would have served as a source of weather sediments or detritus, which is not present in this formation. There is evidence that sea floor subsidence occurred during the greater part of the accumulation of this formation. However, the subsidence was not rapid enough to maintain a constant water level thereby causing explosive erruptions near the top of the formation. Regional uplift occurred near the end of the Water Island. The Louisenhoj Formation of the Virgin Island Group unconformably overlies the Water Island Formation and crops out on about half of the land area on St. Thomas. Pillsbury sound between St. Thomas and St. John was the origin of this formation. Evidence of this center is based upon the coarseness of volcanic ejecta in the formation in nearby eastern St. Thomas and western St. John. Material is less coarse and tuffs are more predominant as you move further east and west away from the center or origin. This Augite-andesite formation ranges in thickness from 4,000 to 13,000 feet. In certain areas of St. Thomas and St. John conglomerates are interbedded with andesitic rocks at the base of this formation. The depositional environment of this conglomerate varies from location to location throughout· formation. ; :. _; ; (; () L :.:;~if.():.:~· - 02-8902-42-PA Rev. No. 0 The Outer Brass Formation of the Virgin Island Group is mostly siliceous limestone which overlie the Louisenhoj, Formation. This limestone formation is an offshore deposit formed by radiolarian and foraminiferal remains including a minor amount of tuff. Thicknesses are known to be up to at least 600 feet. Overlying the Outer Brass Formation is the Tutu Formation. Tutu Formation is fine to coarse- grained volcanic wackes, which is termed flysch. This formation is derived from eroding sediments from the Louisenhoj andesites. Exposed thicknesses are known to be as much as 6000 feet. Within this formation, a megabreccia lithofacies with an average thickness of 30 feet and a limestone member with thickness up to 300 feet is worth mentioning. The Hans Lollik Formation which consists of at least 10,000 feet of augite-andesite pyroclastic rocks, crops out on Little Hans Lollik Island. Dioritic plutons are located in Pillsbury Sound between St. Thomas and St. John; the narrows, between St. John and the British Virgin Islands; and south of St. Thomas. The exact delination of these plutons are uncertain. Throughout the islands isolated dikes of quartz-andesine porphyries, andesine - hornblendes porphyries, lamprophyres, breccias and pegmatites appear. Folding occured after the deposition of the Virgin Island Group. Rocks were tilted to form a northward-dipping homocline, which is cut by sets of faults trending N 45"W, N 55°E and north. Well defined joint sets parallel each of the major fault trends. Dips range from 15° to 90° with the average being 40°. Strike-slip faults have horizontal offsets of less than 1 mile. Two major strike-slip graben structures or fault systems exist. The first passes through Redhook, St. Thomas and the eastern of Lovango Cay. The second crosses St. John, from Contact Point on the southwest to Brown's Bay on the northeast. Most recently Pleistocene to Holocene alluvial deposits occurred primarily in coastal embayments. However, a narrow bank of alluvium extends up to turpentine run on the east end of the island. Most of these deposits are composed of silt, clay, and thin, discontinuous beds of sand and gravel. Maximum thickness of these is 50 feet. Groundwater movement is limited to openings and joints along fault zones. Regional geologic information is insufficient to determine whether these fractures and fault zones are present in all of the above-described formations; however, for this report it is assumed that the fractures and fault zones are present in all of these formations. The valleys on the island are the result of weak zones caused by faulting and jointing and are primary recharge areas for groundwater. Alluvial deposits have a high porosity but low permeability, making this aquifer unfavorable for groundwater production. In coastal embankments throughout the island, saltwater intrusion is widespread in alluvial deposits. In most areas, alluvial deposits are interconnected with bedrock and act to recharge precipitation to the underlying bedrock. The direction of groundwater flow in the Turpentine Run Basin Aquifer is south-southeast which is generally along the direction of flow of turpentine Run. Depth to groundwater in the aquifer ranges from 5 to 60 feet, and the altitude of the water levels ranges from 1 to 209 feet above mean sea level. Ref. Nos. 11, 16 3. Is a designated sole source aquifer within 3 miles of the site? No sole source aquifer, as designated in the Federal Register, is located within 3 miles of the site. Ref. No. 8 i L .. 1 I 02-8902-42-PA Rev. No. 0 4. What is the depth from the lowest point of waste disposal/storage to the highest seasonal level of the saturated zone of the aquifer of concern? Drums in the waste unit were stored on a cement floor at ground level. Depth to groundwater in Virgin Island Housing Authority (VIHA) well Nos. 1 and 2 was reported to be 56 and 60 feet, respectively. The VIHA wells are located about 900 feet southeast of Ramsey Motors. There is a well on the Ramsey Motors property that is used for washing cars. The well is approximately 100 feet deep, but the depth to water in the well is unknown. Ref. Nos. 1, 2, 9 5. What is the permeability value of the least permeable continuous intervening stratum between the ground surface and the aquifer of concern? There are no continuous intervening strata between the ground surface and the bedrock aquifer. Soils are generally thin in the area around the site. The water-bearing formations in the Turpentine Run Basin Aquifer are composed primarily of fractured and jointed volcanic rocks. The range of hydraulic conductivities associated with these formations is 1 Q-3 to 1 o-s cm/sec. Ref. Nos. 10, 11, 16 6. What is the net precipitation for the area? Net precipitation is usually calculated by subtracting mean annual lake evaporation (a surrogate measure for evapotranspiration) from normal annual total precipitation. Mean annual lake evaporation information was not available for St. Thomas; however, evapotranspiration data were available. These data indicate that 95.8 percent of the incident precipitation on St. Thomas is lost through evapotranspiration. The normal annual total precipitation for St. Thomas is 43. 74 inches, but because of orographic effects on the Island, normal annual total precipitation can range from 35 inches to 50 inches over short distances. In the Turpentine Run Basin, normal annual precipitation is 40 inches. Calculations for net precipitation are provided below: 40 inches precipitation x 95.8 percent lost to evapotranspiration = 38.32 inches lost to evapotranspiration 40 inches precipitation - 38.32 inches lost to evapotranspiration = 1 .68 inches net precipitation. Ref. Nos. 3, 5, 12, 13 7. Identify uses of groundwater within 3 miles of the site (i.e., private drinking source, municipal source, commercial, industrial, irrigation, unusable). Groundwater within 3 miles of the site is used as a source of private and municipal drinking water, and for commerical purposes. There are at least 41 wells within 2 miles of the site. Thirty-four of these wells are within 1 mile fo the site. Sixteen of these wells have been closed because they are contaminated with volatile organic compounds. Ref. Nos. 6, 9 8. What is the distance to and depth of the nearest well that is currently used for drinking or irrigation purposes? Distance _ _.:._7..:::c8.;:;..0...;.fe.;:;..e-=-t::.-____ _ Depth __ 1;...;:5"""0-'f-=-e.;:;..et~----- Nearest well is the VIHA well No. 2, which is located approximately 780 feet southeast of Ramsey Motors. This well is believed to be used for drinking. A nearby well, VIHA No. 1, was ordered closed because of contamination with volatile organic compounds. VIHA well No. 2 is not listed as being closed for contamination, and its designated use is for domestic purposes. Ref. Nos. 6, 9 • ·''·) 'I_ 02-8902-42-PA Rev. No. 0 9. Identify the population served by the aquifer of concern within a 3-mile radius of the site. 10. It is difficult to estimate the population served by groundwater on St. Thomas as there are few records available on groundwater withdrawal, sale, and transport. The locations of some wells in St. Thomas are unknown, and there are reports of illegal drilling on the island. It is estimated that there are 500 to 600 private wells on St. Thomas. Most of these are used for nondrinking domestic purposes such as washing and flushing, although some may be used for drinking. There are a number of wells that are used for commercial purposes. Water from these wells is trucked to private houses and pumped into cisterns to augment the rainwater collected from roofs. Groundwater is also bottled and sold in supermarkets. There are at least 41 wells in the Turpentine Run Basin. Recently 16 of these wells have been ordered closed because they were found to be contaminated with volatile organic compounds. One of these wells was a major supplier of water to the eastern end of the island. Estimates of the population using groundwater as a source of drinking water range from none to approximately 11,000--the population of the Turpentine Run Basin which is not served by water from the desalinization plant. The actual population served by groundwater is probably less than 11,000 as desalinated water and water from wells outside the three mile radius is trucked into the area. Ref. Nos.9, 13, 15, 18, 19 SURFACE WATER ROUTE Describe the likelihood of a release of contaminant(s) to surface water as follows: observed, alleged, potential, or none. Identify the contaminant(s) detected or suspected, and provide a rationale for attributing the contaminants to the facility. A very small potential exists for contaminants to be transported to surface water. The waste oil drums are stored inside a garage on a cement floor. There were some minor spills in the area and there were no containment structures around the drums to prevent migration of spills. The drums contain waste oil generated from automotive repair and maintenance activities. Air monitoring instruments indicated the presence of organic vapors in the open drums. Substances such as gasoline, kerosene, and degreasing solvents may also be present in the drums. Waste oil was draining from a ditch on the adjacent Gassett Motors site onto the Ramsey Motors site. Ref. Nos. 1, 2 11. Identify and locate the nearest downslope surface water. If possible, include a description of possible surface drainage patterns from the site. The nearest downslope surface water is the Mangrove Lagoon, which is hydraulically connected to the Caribbean Sea. The distance from the site to the nearest surface water along the course of Turpentine Run is 2.5 miles. There are a number of storm sewers on the site and it is possible that these sewers may intercept much of the runoff from the site. It is unknown where the storm sewers discharge but it is suspected that they discharge to Turpentine Run as it is the only drainage pathway from the basin. Ref. Nos. 2, 4, 5 12. What is the facility slope in percent? (Facility slope is measured from the highest point of deposited hazardous waste to the most downhill point of the waste area or to where contamination is detected.) The facility is relatively flat with a slight slope toward the south-southeast. Facility slope is estimated to be Oto 3 percent •_;(_., .L /i.j.i)' .. :, Ref Nos 1, 2 02-8902-42-PA Rev. No. 0 13. What is the slope of the intervening terrain in percent? (Intervening terrain slope is measured from the most downhill point of the waste area to the probable point of entry to surface water.) The slope of the intervening terrain is as follows: • Elevation of waste area 240 ft • Elevation at point of entry Oft • Path length 13,200 ft 240 ft- 0 ft x 100 = 1.8% slope 13,200 ft Ref. Nos. 1, 2 14. What is the 1-year 24-hour rainfall? 1-year 24-hour rainfall data was not available for the U.S. Virgin Islands. However, it is known that rains exceeding 1 inch in 24 hours occur six or seven times a year on St. Thomas. Two-year 48-hour rainfalls range from 4 to 15 inches. It has also been reported that it is not uncommon for 24-hour rainfalls to be 2 to 3 inches. Ref. Nos. 4, 6 15. What is the distance to the nearest downslope surf ace water? Measure the distance along a course that runoff can be expected to follow. The nearest downslope surface water is the Mangrove Lagoon which is hydraulically connected to the Caribbean Sea. The distance from the site to the lagoon is 2.5 miles. It appears that most runoff fromthe site enters storm drains near the site. Since the point of discharge and the route of these storm drains is unknown, the distance to the nearest downslope surface water along the pathway is unknown.· Ref. No. 2 16. Identify uses of surface waters within 3 miles downstream of the site (i.e., drinking, irrigation, recreation, commercial, industrial, not used). Surface water within 3 miles downstream of the site is used for recreation including swimming, fishing, and boating. The DPNR has designated the area of the Mangrove Lagoon for preservation and conservation recreation. Ref. Nos. 2, 14 17. Describe any wetlands, greater than 5 acres in area, within 2 miles downstream of the site. Include whether it is a freshwater or coastal wetland. There are no wetlands greater than 5 acres within 2 miles downstream of the site. However, there is a coastal Mangrove wetland approximately 2.5 miles downstream. The Mangrove Swamp is designated as a preservation area in the Coastal Zone Management Program of the DPNR. Ref. Nos. 2, 14 18. Describe any critical habitats of federally listed endangered species within 2 miles of the site along the migration path. There are no known critical habitats of federally endangered species within 2 miles of the site. The Virgin Islands Tree Boa (Epicrates monensis granti) is an endangered species in the U.S. Virgin Islands; however, no critical habitat has been identified for this species. Ref. No. 7 19. What is the distance to the nearest sens1t1ve environment along or contiguous to the migration path (if any exist within 2 miles)? There are no sensitive environments within two miles of the site that lie ale to the migration pathway Ref Nos 2, 7, 14 ;Ui 02-8902-42-PA Rev. No. 0 20. Identify the population served or acres of food crops irrigated by surface water intakes within 3 miles downstream of the site and the distance to the intake(s). There is no population served or food crops irrigated by surface water intakes within 3 miles downstream of the site. The nearest surface water is saline. There is a desalinization plant which uses sea water to supply drinking water, but the intake is greater than 3 miles from the site. Ref. Nos. 2, 13 21. What is the state water quality classification of the water body of concern? No water quality classification is known to exist for the Mangrove Lagoon or the Caribbean Sea, although the mangrove swamp surrounding the lagoon is designated as a preservation area by the DPNR. Ref. No. 14 22. Describe any apparent biota contamination that is attributable to the site. No apparent biota contamiantion was observed during the on-site reconnaissance conducted by NUS Corp. Region 2 FIT on February 15, 1989. Ref. No. 1 AIR ROUTE 23. Describe the likelihood of a release of contaminant(s) to the air as follows: observed, alleged, potential, none. Identify the contaminant(s) detected or suspected, and provide a rationale for attributing the contaminant(s) to the facility. The potential for release of contaminants to the air is very small. Above-background concentrations of organic vapors were detected in drums using an OVA and HNu; however, no readings above background were detected in the ambient air in the drum storage areas. The drums on site contain waste oil from automotive repair and servicing operations. The drums may also contain small quantities of gasoline, kerosene, or degreasing solvents. Ref. Nos. 1, 2 24. What is the population within a 4-mile radius of the site? Based on the 1980 census, the population within 4 miles of the site is approximately 36,000. Ref. No. 17 FIRE AND EXPLOSION 25. Describe the potential for a fire or explosion to occur with respect to the hazardous substance(s) known or suspected to be present on site. Identify the hazardous substance(s) and the method of storage or containment associated with each. No significant fire or explosion conditions are known or suspected to be present on the site. Ref. No. 1 26. What is the population within a 2-mile radius of the hazardous substance(s) at the facility? Based on the 1980 census, the population within 2 miles of the site is approximately 19,000. Ref. No. 17 ! : __ ;i 'J ..i DIRECT CONTACT/ON-SITE EXPOSURE 02-8902-42-PA Rev. No. 0 27. Describe the potential for direct contact with hazardous substance{s) stored in any of the waste units on site or deposited in on-site soils. Identify the hazardous substance{s) and the accessibility of the waste unit. There is little potential for direct contact with substances stored in the waste unit. Although the bungs are open on some of the drums and there are some spills, the drums are not located in an area that is frequented by customers. Access to the site is controlled by a fence. There is potential for workers to come in contact with waste oil in the course of performing their jobs. Ref. No. 1 28. How many residents live on a property whose boundaries encompass any part of an area contaminated by the site? There is no evidence that any residential areas have been contaminated by the site. Ref. No. 1 29. What is the population within a 1-mile radius of the site? Based on the 1980 census data, the population within 1 mile of the site is approximately 11,000. Ref. No. 17 - PART IV: SITE SUMMARY AND RECOMMENDATIONS 02-8902-42-PA Rev. No. 0 The Ramsey Motors Site is located in the Tutu area of St. Thomas, U.S. Virgin Islands. Ramsey Motors is engaged in the sale, maintenance and repair of automobiles. The area within approximately 1 mile of the site is densely populated and contains some commercial properties. There are large housing developments northeast, southeast, and west of the site. The nearest residence is approximately 400 feet southwest of the site. The densely populated and highly commercial town of Charlotte Amalie, which is the capital of St Thomas, is located 2.3 miles east of the site. There are twenty-five 55-gallon drums of waste oil stored on a concrete floor along the inside perimeter of the Ramsey Motors automotive garage. Some of the drums were open and there were spills on the garage floor during the on-site reconnaissance conducted by NUS Corp. on February 15, 1989. Readings ranging from 10 to 90 ppm and 60 to 300 ppm were detected on the HNu photoionization detector and the OVA flame ionization detector, respectively, during the reconnaissance. Waste oil was noted discharging from a pool on the adjacent Gassett Motors Property into a drainage ditch on the Ramsey Motors Site. Until June 1986, the Virgin Islands Water and Power Authority (WAPA) accepted waste oil generated by marinas, airports, and auto maintenance facilities. The waste oil was blended with fuel and burned as a source of power. WAPA stopped accepting waste oil when a batch was found to contain PCBs. The source of the PCBs is unknown. Since 1986, there has been no permitted method of waste oil disposal on St. Thomas. Generators must store their waste oil, but the facilities are not inspected or issued storage permits. These conditions combined with drum shortages and poor housekeeping has resulted in generally poor waste containment at many of the facilities. As mentioned previously, the waste oil drums on the Ramsey Motors Property are not properly stored or contained. Many of the drums are open and there is oil pooled on the floor. The garage where the drums are stored has a concrete floor and an overhang roof, but the walls are not continuous and small quantities of oil appeared to be leaking into the soil in a few areas. There are no berms to contain the oil in the event of a spill. Although there is a potential for the waste oil to be released to the environment, the waste oil drums on the site do not currently pose a significant threat to groundwater or surface water resources in the vicinity of the site. As a result, a recommendation of NO FURTHER REMEDIAL ACTION PLANNED is provided. Any potential for release of the oil to the environment could be significantly reduced if the drums are properly stored and contained, and the spilled oil is cleaned up. It is recommended that the responsible local or federal department ensure that the waste is properly stored and contained. i LJ I 02-8902-42-PA Rev. No. 0 No enforcement actions have been taken against Ramsey Motors in the past. The owners of the Ramsey Motors property have been identified as one of nine potentially responsible parties in the contamination of groundwater in the Tutu area. In July and August of 1987, EPA confirmed by sampling that volatile organic compounds were present in a number of wells in the Tutu area. DPNR has issued orders to close 16 wells in the area. EPA removal action activities in the Tutu area included: sampling of wells and cisterns, removal of contaminated water from cisterns, and supplying clean water on a regular basis to affected residents. \I../\ ATTACHMENT A MAPS AND PHOTOS RAMSEY MOTORS ST.

Since early in the nineteenth century rainiall in the Virgin Islands has been measured in a unique unit of depth, called the "'line". The reason ior the adoption oi this measure is not known. It is an old English measure. in which I inch = 8 lines ( = 25.-tO millimeters). In Denmark they once used the Paris measure oi 12 Li11ie11 = I T 0111rne ( Paris inch) = 27.07 milli- meters= 1.0658 inches. I Paris line= 2.256 mm= .0888 inch= ~{ 44 foot. whereas the Danish f!'cst flldian (or English) line= 3.175 mm= L8 inch. It is conceivable that as many of the residents were British this "line" was adopted locally irom using English rain-measuring glasses or sticks graduated in eighths oi an inch. Since the . .\merican occupation inches ha\'e been used. Accuracy of the Measurements The accuracy oi rainfall measurements is a difficult problem in gen- eral. and is especially serious in tropical conntries. * \Ve have already re- f erred to the lack oi standards in the instruments and obsen·ation pro- cedures at \'irgin Islands stations. and here we mnst add that where the rainfalls are frequently light and the monthly and annual totals are small the errors oi measurement are greatest on a percentual basis. The common practice of measuring the catch only once each 2-t hours allows some water to evaporate irom the gage beiore it is read. particularly in a warm windy climate. The use oi a funnel is common and tends to cut down the evapo- ration. \\"here most of the rain falls at night. it is better to read the gage in the mornirn~. and where it ialls mor<: in the day an e\·ening ohsern.tion hour is pre ierable: two readings a
