DESCRIPTIONS OF EIGHT SITES DELETED FROM THE NATIONAL PRIORITIES LIST IN MARCH 1986 This document consists of descriptions of the eight sites deleted on March 1, 1986 (51 FR 7934) from the National Priorities List. On December 31, 1985 (50 FR 53448), the U.S. Environmental Protection Agency (EPA) announced its intention to delete the sites and solicited comments on the action for a 30-day period. Earlier, EPA had provided a local comment period in each of the eight communities involved. The sites were deleted because EPA has determined that no further response is appropriate, in accordance with section 300.66(c)(7) of the National Contingency Plan, the Federal regulation under which the Comprehensive Environmental Response, Compensation and Liability Act is implemented. Sites are arranged alphabetically by State and by site. ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response. Compensation, and Liability Act of 1980 (CERCLA)("Superfund" TAPUTIMU FARM Island of Tutuila, American Samoa Conditions at listing (October 1981): The Taputimu Farm Site is on the Island of Tutuila, Trust Territory of American Samoa. The site, part of an experimental farm owned by the Territory, consists of three rooms of a farm warehouse and a trailer which have been used in excess of 10 years for storage of unused and out-of-date agricultural chemicals and pesticides. Approximately 4,000 pounds of hazardous wastes are on-site. The chemical storage areas are a short distance from a public beach area, and a primary concern is that these materials could be transported by flood water to the beach 0.3 miles away. Direct human contact and contami- nation of drinking water and marine resources used for food are of concern. This is the top priority site in American Samoa. Response Actions; In 1982, EPA conducted a remedial investigation/ feasibility study (RI/FS). The materials were found to be improperly stored within the buildings. Analysis of the materials identified several pesticides and chlorinated organic solvents. The materials were stored on a concrete or steel floor of the storage areas and trailer. Soil sampling and visual examination of the site confirmed that contamination was confined to the interior floors. The remedial action alternative selected and implemented at Taputimu Farm in 1984 involved repacking the chemical/pesticide materials for shipping to the continental United States for disposal in a facility permitted under the Resource Conservation and Recovery Act. The remedial action also included washing down all exposed surfaces of the storage areas with bleach to ensure deactivation of any residual materials not picked up by sweeping and vacuuming. Finally, two layers of epoxy paint were applied to the interior walls and 3 inches of concrete were poured over the existing floor, thereby eliminating the threat of direct contact. The Government of American Samoa uses the structure only to store farm equipment and has placed signs on the building prohibiting food storage. Since all materials were removed and contaminated surfaces cleaned and sealed, no further monitoring was conducted. , EPA, with the concurrence of the Government of American Samoa, has determined that all appropriate Fund-financed response under CERCLA has been completed at the Taputimu Farm Site, and that no further cleanup by responsible parties is appropriate. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)("Superfund") PCB WAREHOUSE Saipan, Commonwealth of the Northern Mariana Islands Conditions at listing (October 1981); The PCB Warehouse on Saipan, Commonwealth of the Northern Mariana Islands, is a temporary shelter built to store about 1,400 gallons of transformer fluid containing up to 25,000 parts per million of PCBs. The fluid is stored in drums awaiting shipment or off-site disposal. The storage site is adjacent to the Philippine Sea, an area subject to tropical storms. PCB contamination of drinking water and marine resources used for food is of concern. This is the top priority site in the Northern Mariana Islands. Response Actions; A remedial invesigation of the site conducted by EPA in December 1982 revealed the presence of 21 drums of PCB-contaminated oil and 3 crates of sodium arsenite. Drums were found to be intact and there was no evidence of any reported spills or leaks. The transformers from which the oil had been drained were at the Saipan Headquarters Building and at the Department of Public Works Yard. There was no indication of leaks or spills near those transformers. In 1984, EPA used CERCLA emergency funds to remove the 21 drums of PCB wastes and 3 crates of sodium arsenite. These were repackaged and transported to the continental United States for disposal at a facility meeting the requirements of the Toxic Substances Control Act. The sodium arsenite was disposed of in the continental United States at a facility permitted under the Resource Conservation and Recovery Act. Tests confirmed that no PCB wastes had been spilled during the removal action. { EPA, with the concurrence of the Commonwealth of the Northern Mariana , Islands, has determined that all appropriate Fund-financed response under CERCLA has been completed at the PCB Warehouse Site, and that no further cleanup by responsible parties is appropriate. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)C'Superfund") MORRIS ARSENIC DUMP Morris, Minnesota Conditions at listing (September 1983): Morris Arsenic Dump is an old gravel pit covering 5 acres in a rural area about 1 mile northeast of Morris in Stevens County, Minnesota. In the early 1940s, about 1,500 pounds of arsenic-laced grasshopper bait ware on the site. The subsequent construction of a highway in the area may have dispersed the bait and made it difficult to discover the exact burial location. Tests by EPA have detected arsenic in the shallow ground water. The City of Morris and private wells in the area draw on shallow ground water. No drinking water wells have been affected to date. Response Actions; In 1984, as part of a remedial investigation (RI), EPA installed 11 monitoring wells around the site and sampled soil in the site area. The results of the RI indicate that arsenic levels in the surface soils were all below 7 micrograms per kilogram (-g/kg), well within the natural background range of 3 to 14 ;g/kg. Arsenic concentrations in the soils at the water table were somewhat elevated, ranging between 20 and 40ug/kg, but far below the Centers for Disease Control (CDC) action level of 100//g/kg for surficial soils. CDC was consulted with respect to the soils and concurred that no action was necessary. Samples from the monitoring wells and nearby domestic sources indicate that arsenic levels were considerably below the Primary Drinking Water Standard of 50 micrograms per liter (o'_g/l). Arsenic was found to be at or near S^g/l. The municipal well field for Morris is approximately 1 mile in the opposite direction of ground water flow and would not be impacted by any contamination at the site. Other domestic wells sampled in the vicinity did not have arsenic contamination above background. EPA, with the concurrence of the State of Minnesota, has determined that the Morris Arsenic Dump poses no significant threat to public health or the environment and, therefore, taking remedial measures is not appropriate. EPA has recommended to State, county, and local officials that, as a further precaution, a notice be placed on the property. The deed notice would be entered in county land records and state that the site had previously been used for the disposal of a hazardous substance. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the : * Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)("Superfund") FRIECMAN PROPERTY Upper Freehold .Township, New. Jersey Conditions at listing (October 1981); The Friedman Property is located in Upper Freehold Township, Mbnmouth County, New Jersey, (The site was once listed under the name "Upper Freehold Site.") The 3-acre site lies just across the boundary from Plumstead Township and-is immediately adjacent to an unnamed tributary to Lahaway Creek, which is itself a tributary of the Delaware River. In the late 1950s and early 1960s, free-flowing liquids, household wastes, and demolition debris were dumped into a natural ditch and then covered over. Several residences and two trailer parks within 0.3 miles of the site have private wells. Four monitoring wells installed in 1980 by New Jersey detected heavy metals and a number of organic pollutants. Organic chemicals were present in an adjacent stream. Response Actions; In 1984, EPA and the New Jersey Department of Environmental Protection (NJDEP) completed a remedial investigation/ feasibility study (RI/FS) covering the air, soils, wastes, ground water, surface water, and adjacent stream sediments. The RI results indicate that limited contamination is present at the site, and that the site was not used as a hazardous waste disposal facility. Its wastes were no different than those of a typical municipal landfill. Air monitoring during the RI/FS did not show levels above ambient air quality standards, and no complaints of odors or fumes were received from area citizens before or during testing, or from personnel conducting the RI/FS. Ground water testing included the installation of six monitoring wells and sampling of domestic wells in the vicinity of the site. The shallow ground water had slightly elevated levels of zinc — below 0.5 milligrams per liter (mg/1) — and 0.03 mg/1 of phenols. These levels are below current EPA Health Effects Assessment levels of 7.4 mg/1 for zinc and 3.5 mg/1 for phenols. Analysis of deep ground water revealed only zinc at levels comparable to surface levels. The only similarity between the shallow and deep ground water is in naturally occuring zinc. Since similar chemicals were not found in the two aquifers, and geologic analysis indicates no interconnections, there is no indication that the lower aquifer is contaminated or will be in the future. The RI/FS indicated that the adjacent stream sediments had not been significantly contaminated by materials found at the site, although trace contamination consistent with routine road maintenance practices from the adjacent highway was found. In summary, the RI/FS concluded that there are no significant sources of contamination at the site, and contaminants have not migrated from the site and are not expected to migrate. Therefore, no remedial action was appropriate. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)("Superfund") EPA, with the concurrence of the State of New Jersey, determined that the Friedman Property Site poses no significant threat to public health or the environment and, therefore, taking remedial measures is not appropriate. However, EPA the NJDEP have agreed that the shallow aquifer in the vicinity of the site will be monitored as a precautionary measure to ensure that current site conditions do not change. The State is responsible for periodic ground water monitoring for 5 years. State monitoring to date indicates that conditions remain unchanged. As an additional precaution, EPA recommended to State, county, and local officials that a notice be placed on the property deed and the plot plan amended. The deed notice and plot restrictions would be entered in county land records. They would note that the site had previously been used for waste disposal and restrict on-site excavations, agricultural, and residential use. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980'(CERCLA)("Superfund") PCB SPILLS 243 Miles of Road in North Carolina Conditions at listing (October 1981): Between June and August 1978, over 30,000 gallons of industrial waste containing PCBs were deliberately discharged along approximately 243 noncontiguous miles of highway shoulders in 14 counties of North Carolina. In late August, the State covered the: spill areas with activated charcoal and liquid asphalt.. Because, of the quantity of soils involved and the distances to approved landfills, the State decided to construct a new landfill. In December 1978, North Carolina sought EPA approval for a PCB landfill in Warren County. EPA approved the landfill site in June 1979, subject, to compliance with a number of technical and procedural conditions. The State conducted several investigations and feasibility studies between 1979 and 1981 and ascertained that contamination did not migrate from the spill areas into surface water, biota, or ground water.. This is the top priority site in North Carolina. Response Actions; In May 1982, EPA and the State initiated remedial action to: (1) construct a landfill meeting the requirements of the Toxic Substances Control Act for disposal of PCB wastes; (2) remove, transport, and dispose of contaminated soils; and (3) reconstruct the highway shoulders. Disposal of contaminated soil was completed in November 1982, and the landfill was capped, graded, and vegetated. During soil removal, the beginning and end point of each contaminated strip were sampled to ensure that contaminated soils were removed. Random samples were collected after soils were removed. Analyses indicated that nearly all samples contained 10 parts per million (ppm) or less of PCBs. No soils with PCBs above 50 ppm were left in place. Excavated areas were then filled with clean soil. EPA, with the concurrence of the State of North Carolina, has determined that all appropriate Fund-financed response under CERCLA at the PCB Spills Site has been completed, and that no further cleanup by responsible parties is appropriate. The State is currently, monitoring the landfill constructed to contain contaminated soils removed from the site. The results indicate that the landfill continues to meet all requirements for postclosure monitoring. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)C'Superfund") ENTERPRISE AVENUE Philadelphia, Pennsylvania Conditions at listing (December 1982); The Enterprise Avenue Site covers about 57 acres along the Delaware River in an industrial area of Philadelphia, Pennsylvania. Fran 1971 to mid-1976, the city operated the site as a landfill. Several waste-handling firms buried at least 10,000 drums of hazardous wastes there without the city's permission. During exploratory excavations in January 1979, the Philadelphia Water Department discovered approximately 1,700 drums that contained or had once contained wastes such as paint sludges, solvents, oils, resins, metal-finishing waste, and solid inorganic wastes. In 1982, the city started cleanup actions, including removal of drums and soil to a landfill permitted under the Resource Conservation and Recovery Act (RCRA). A total of 32,800 cubic yards of excavated soil was identified as contaminated with organic chemicals (toluene, benzene, ethylbenzene, or organic halogenated compounds) In October 1982, after spending $7 million cleaning up the site, the city ran out of money. Left on-site were approximately 20,000 tons of contami- nated soil in two piles that had been partially covered. Response Actions; In 1984, EPA and the city started to complete the remedial actions. All of the spockpiled soils were analyzed for a variety of metals and organic chemicals. Soils were divided into 100-cubic-yard lots. A Key Indicator Analysis was used to determine which lots would be disposed of in an off-site facility. If any one indicator exceeded action levels, the entire soil lot was deemed contaminated and sent off-site. Action levels for inorganics were selected based upon the Extraction Procedure Ibxicity Test used to determine if a waste is hazardous under RCRA. Organic action levels were established using similar methodology and are consistent with levels that would be used today. After removal of contaminated soils from the site, the area was sampled on a grid pattern to ensure that all soils not passing the test had been transported off-site. The results indicate that the remedial objectives were attained, and that all soils considered contaminated were removed. The site was then capped, seeded, and fenced. EPA, with the concurrence of the Commonwealth of Pennsylvania, has determined that all appropriate Fund-financed response under CERCLA at the Enterprise Avenues Site has been completed, and that no further cleanup by responsible parties is appropriate. The Pennsylvania Department of Environmental Resources has agreed to operate and maintain the site. The department has also developed and implemented an operations and maintenance plan for the cap and will monitor ground water to ensure that water quality remains at background levels. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)("Superfund") LEHIGH ELECTRIC & ENGINEERING CO. Old Forge Borough, Pennsylvania Conditions at listing (October 1981); The Lehigh Electric & Engineering Co. Site, in Old Forge Borough, Lackawanna County, Pennsylvania, occupies approximately 5.4 acres adjacent to the Lackawanna River. The company operated a storage and repair facility for electrical equipment fron the mid-1970s until March 1981. On-site are 4,000 pieces of equipment, some contaminated with PCBs. Analyses indicate that extremely high levels accumulated in the soil due to the indiscriminate disposal of dielectric fluids containing PCBs. Contamination of ground water and surface water is possible because the soil is highly permeable and the site is in the floodplain. In April 1981, with funds made available under Section 104 of the Clean Water Act, EPA fenced the site and analyzed soil and water samples. In September 1981, using funds made available under the Resource Conservation and Recovery Act, EPA started a remedial investigation/feasibility study (RI/FS)to determine the type and extent of contamination at the site and identify alternatives for remedial action. Response Actions; The RI/FS, completed in 1983, included the analysis of ground water, air, and river sediment samples, and the evaluation of cleanup alternatives. In Phase I of the remedial action, all transformers, transformer contents, and surface debris were removed frcm the site. This was completed in December 1982. In Phase II, contaminated soils and buildings were removed from the site, which was then backfilled, graded, and vegetated. These actions were completed in September 1984. Analyses conducted during excavation showed that the remedial action reduced the concentration of PCBs in soils to 10 parts per million. Contaminated soils were transported to a disposal facility meeting the requirements of the Toxic Substances Control Act. In May 1985, EPA inspected the site, collected samples, and verified that the objectives of the remedial action were met. After the contaminated soils were excavated, the remaining soils containing low levels of PCBs were buried beneath 10 to 15 feet of clean backfill. PCBs are not readily soluble in water so that any PCBs remaining are not expected to impact ground water; no PCBs were detected in ground water samples taken during the RI/FS. EPA, with the concurrence of the Commonwealth of Pennsylvania, has determined that all appropriate Fund-financed response under CERCLA at the Lehigh Electric & Engineering Co. Site has been completed, and that no further cleanup by responsible parties is appropriate. The Pennsylvania Depatment of Environmental Resources has agreed to perform all future operation and maintenance, including the continued monitoring of ground water for PCBs. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Site Hazardous waste site listed Comprehensive Environmental RfcpllWegtapwsatMKiaflfli Liability Act of 19gO (CERCLA)("Superfund") PCB WASTES Trust Territory of the Pacific Islands Conditions at listing (October 1981): The Trust Territory of the Pacific Islands, an area.larger than the continental United States, has eight separate areas for storing transformers contaminated with PCBs. The sites were located on the islands of Koror in the Republic of Palau, Moen in Truk State, Yap, Kosrae, and two on both Ponape and Majuro. The storage areas, which hold more than 2,000 gallons of wastes, are unprotected and could contaminate ground water and surface water used as drinking water. Contamination of marine resources used for food could also result. Wastes migrating from sane of these sites may already have contaminated the surrounding area. This is the top priority site in the Trust Territory. Response Actions; A remedial investigation conducted by EPA in December 1982 revealed that the PCBs in drums and transformers and some pesticides and chemicals were improperly stored. A previous oil spill was apparent at one location formerly used to store transformers. In seme locations, intact containers of transformer oil were in unsecured areas open to the general public. In 1984, EPA used CERCLA emergency funds to remove wastes containing over 50 parts per million (ppm) of PCBs and the other hazardous wastes found at the various locations. During the removal action, soils and waste oils were sampled in the field using a portable testing kit that allowed segregation of wastes for transport. Only the transformer storage area had contaminated soils. It is located in a fenced in rural area. Testing was conducted in the area before and after removal of contaminated soils. No PCBs above 50 ppm were found in structures or soils after removal. Fluids containing under 50 ppm of PCBs were blended and burned on the islands. Other PCB wastes were transported to a disposal facility in the continental United States meeting the requirements of the Toxic Substances Control Act. Other hazardous wastes were removed and transported to a facility in the continental United States permitted under the Resource Conservation and Recovery Act. EPA, with the concurrence of the Trust Territory of the Pacific Islands, has determined that all appropriate Fund-financed response under CERCLA has been completed at the PCB Wastes Site, and that no further cleanup by responsible parties is appropriate.
