Unital States HW-8.12 Environmental Protection Agency July 1987 DESCRIPTIONS OF 149 SITES PROPOSED FOR THE NATIONAL PRIORITIES LIST AS OF JULY 1987 This document consists of descriptions of the 149 sites (including 16 Federal facility sites) proposed for the National Priorities List (NPL) as of July 1987. Summaries were provided earlier when the sites were first proposed. As a convenience, they are compiled here into one document. In some (but not all) cases, there is a status section describing activities subsequent to proposal. The size of the site is indicated on the basis of presently available information. The size may change in the future as additional information is gathered on the extent of contamination. All sites are arranged alphabetically by State and by site. Remedial Responses Under Superfund The Superfund program is authorized by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund Amendments and Reauthorization Act (SARA), enacted on October 17, 1986. Under SARA, the Hazardous Substances Superfund pays the costs not assumed by responsible parties for cleaning up hazardous waste sites or emergencies that threaten public health, welfare, or the environment. The Superfund program is managed by the U.S. Environmental Protection Agency (EPA). Two types of responses may be taken when a hazardous substance is released (or threatens to be released) into the environment: 0 Removal actions: emergency-type responses to imminent threats. Typically., these actions were limited to fi months and/or SI million under CERCLA. Under SARA, they are limited to 1 year and/or $2 million, with a waiver possible if the actions are consistent with remedial actions. Removal actions can be undertaken by the private parties responsible for the releases or by the Federal Government using the Superfund. 0 Remedial responses: actions intended to provide permanent solutions at abandoned or uncontrolled hazardous waste sites. They are generally longer-term and more expensive than removals. A Superfund remedial response can be taken only if a site is on the NPL. After publishing two preliminary lists and proposing a formal list, EPA published the first NPL in September 1983. The list must be updated at least annually. ------- -2- - The money for conducting a remedial response or removal action can ccme from several sources: 0 The party or parties responsible for the problem can clean up voluntarily with EPA or State supervision. 0 The responsible party or parties can be forced to clean up by Federal or State legal action. 0 Superfund can pay for the cleanup, then seek to recover the costs from the responsible party or parties. 0 A State or local government can choose to assume the responsibility to clean up without Federal dollars. A remedial response at an NPL site is an orderly process that generally involves the following steps: 0 Take any measures needed to stabilize conditions, which might involve, for example, fencing the site or removing above-ground drums or bulk tanks. 0 Undertake initial planning activities to scope out a strategy for collecting information and analyzing alternative courses of action. 8 Conduct a remedial investigation to determine the type and extent of contamination at the site. 0 Conduct a feasibility study to. analyze various cleanup alternatives. The feasibility study is often conducted with the remedial investigation as one project. Typically, the two together cost $875,000 and take from 9 to 18 months to complete. 0 Select the cleanup alternative that: Protects human health and the environment Attains Federal and State requirements that are applicable or relevant and appropriate Makes maximum use of permanent solutions, alternative treatment technologies, or resource recovery technologies Is "cost effective" that is, the results achieved are proportionate to the cost (tentative working definition) 0 Design the remedy. Typically, the design phase costs 5850,000 and takes 6 to 12 months. 0 Implement the remedy, which might involve, for example, constructing facilities to treat ground water or removing con- taminants to a safe disposal area away frcm the site. The implementation phase typically lasts 6 to 12 months. ------- The State government can participate in a remedial response financed by Superfund in one of two ways: 0 The State can take the lead role under a cooperative agreement, which is much like a grant in that Federal dollars are trans- ferred to the State. The State then develops a workplan, schedule, and budget, contracts for any services it needs, and is responsible for making sure that all the conditions in the cooperative agreement are met. In contrast to a grant, EPA continues to be substantially involved and monitors the State's progress throughout the project. 0 EPA can take the lead under a Superfund State Contract with the State having an advisory role. EPA, generally using contractor support, manages work early in the planning process. In the later design and implementation (construction) phases, contractors do the work under the supervision of the U.S. Army Corps of Engineers. Under both arrangements, the State must share in the cost of the implementation phase of cleanup. EPA expects this phase to average out at about S10-12 million per site. ------- National Priorities List She Hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)("Superfund") ANNISTON ARMY DEPOT (SOUTHEAST INDUSTRIAL AREA) Anniston, Alabama Conditions at listing (October 1984): Anniston Ordnance Depot, which occupies approximately 30 square miles in Anniston, Calhoun County, Alabama, was officially designated as an ammunition storage area on October 14, 1941. Over the years, operations were expanded to include the overhauling and repairing of combat vehicles and artillery equipment. The facility is currently referred to as the Anniston Army Depot (ANAD). This NPL site consists of six different disposal operations covering 600 acres in and adjacent to the Southeast Industrial/Vehicle Rebuild Area. The six disposal operations were combined to form this NPL site. Five are waste disposal pits or lagoons containing liquid chemical and industrial wastes contaminated with heavy metals and chlorinated organic solvents. At the sixth location, drums containing calcium hypochlorite (bleaching powder) were buried. According to analyses reported by the Army in 1982, metals and chlorinated solvents were present in the ground water beneath the ANAD Southeast Industrial Area. Ground water is the source of drinking water for Calhoun County residents. The hydrogeology of Calhoun County is very complex and requires further studies to define possible aquifer inter- connections. The highly fractured bedrock apparently is the source rock for Coldwater Spring, which supplies private and public water. The spring may be connected via fractures to contaminated ground water at the ANAD site. The Anniston municipal water supply system provides drinking water for an estimated 39,000 people. ANAD is participating in the Installation Restoration Program, the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past hazardous waste sites and controlling the migration of hazardous contaminants from these sites. The Army has completed Phase I (records search), Phase II (pre- liminary survey), and Phase III (assessment of remedial action alterna- tives). Two portions of the site (encompassing approximately 5 acres) have been closed under the Resource Conservation and Recovery Act (RCRA). Wastes and contaminated soils from those two areas were excavated and removed to a permitted facility. Status (April 1987); EPA is reviewing an Army study of ground water beneath 31 RCRA and CERCLA solid waste management units at ANAD, including the Southeast Industrial Area. The Army is conducting an Endangerment Assessment that will include a summary of all previous activities. This site is being reproposed to be consistent with EPA's recently proposed policy for placing on the NPL sites located on Federally-owned facilities that are subject to the corrective action authorities of RCRA Subtitle C. EPA is soliciting comments on the Hazard Ranking System score for the site, which includes areas subject to RCRA Subtitle C corrective action authorities. 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") APACHE POWDER CO. tv Benson, Arizona :; \£ ' s Apache Powder Co. has manufactured explosives and fertilizers since 1929 in Benson, Cochise County, Arizona. Large quantities ofy nitrates have been used. Prior to 3971, all waste water drained to.;.dtry washes on- site that flowed to the San Pedro River. Since that time/waste water has been contained in unlined ponds ranging from 6 to 8 feet 'deep and covering more than 10 acres. The waste water contains elevated levels of nitrate. In ]982, EPA found more than 13,480 parts per million nitrate nitrogen in a sample. Soil in the bottom of the dry ponds also contains high levels of nitrate nitrogen, as does ash in a burning ground located in a dry wash. EPA detected toxic heavy metals in the lagoons and on-site wells at levels above drinking water standards. Downgradient of" Apache Powder, 11 shallow wells contain nitrate nitrogen in excess of the drinking water standards, according to .EPA. The maximum concentration found was in the well closest to Apache Powder. Nitrogen isotope analysis of this well positively identified Apache Powder's ponds as the source, but was inconclusive for other wells. Nine of the 11 wells were used for drinking water. About 900 people get drinking water from the shallow aquifer within 3 miles of the site. Because nitrate is very mobile, it is likely that it precedes the migration of toxic heavy metals, which will likely follow the same path. A deeper artesian aquifer is not contaminated to date, but there may be danger of contamination in the future. EPA has also detected elevated nitrate levels in the San Pedro River, which borders the plant. 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" MESA AREA GROUND WATER CONTAMINATION Mesa, Arizona Volatile organic solvents contaminate five wells in Mesa, Maricopa County, Arizona. Trichloroethylene, tetrachloroethylene, 1,1,-dichloro- ethylene, 1,1,1-trichloroethane, and Freon-113 were detected in tests conducted by the Arizona Department of Health Services and the City of Tempe. Two of the wells are owned by the Cities of Mesa and Tempe. The other three are owned by the Salt River Project and pump into the Tempe Canal, a source of irrigation water for about 20,000 acres and a source of raw water for the South Tempe Municipal Water Treatment Plant. The area is highly urbanized, and the Tempe well pumps into a municipal supply system serving an estimated 126,000 people. EPA is in the process of identifying potential sources of the contami- nation. 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" MOTOROLA, INC. (52ND STREET PLANT) Phoenix, Arizona Conditions at listing (October 1984); Motorola, Inc., manufactures semiconductors and related components at a plant on 52nd Street in Phoenix, Maricopa County, Arizona. The facility is situated approximately 1.5 miles northeast of the Sky Harbor International Airport and is surrounded by residential, industrial, business, agricultural, and recreational areas. Ground water beneath the 52nd Street Plant is contaminated with tri- chloroethylene (TCE),trichloroethane (TCA), and other organic and inorganic compounds, according to analyses conducted by EPA and Motorola. Contami- nation may have resulted from leaking storage tanks, leaking effluent lines, and past disposal practices, including the use of dry wells. Motorola detected TCE and TCA in its off-site monitoring wells located at least 1 mile from the facility. Analytical results indicate that several private wells not used for drinking and one irrigation well contain TCE concentrations above the State action level of 5 parts per billion. Prior to October 1983, Motorola installed 22 on-site and 6 off-site monitoring wells. This work was described in a Phase I remedial investi- gation report. In October 1983, the Arizona Department of Health Services established a Task Force comprised of the State, EPA, -and local agencies to guide and evaluate Motorola's remedial activities. The Task Force has guided Motorola in development of a detailed workplan for a remedial investigation/feasibility study (RI/FS) to determine the type and extent of contamination at the site and identify alternatives for remedial action. The RI/FS workplan was aporoved in October 1984, and Phase II of the RI was begun. The plant received Interim Status under the Resource Conservation and Recovery Act (RCRA) when the company filed Part A of a permit application. Status (January 1986); Motorola has completed most of the field activities planned for Phase II of the RI/FS. The report is expected to be completed in 1986. Off-site well sampling has confirmed a plume extending at least 1 mile west of the plant. In 1986, additional monitoring wells will be installed, around water and soil testing will be conducted, and a pilot plant for pumping and treating contaminated ground water will be installed. This site remains in proposed status until EPA implements the appropriate elements of its final policy for placing RCRA-related sites on the NPL and then applies the policy to this site. 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' ARKWCOD, INC. Qnaha, Arkansas Conditions at listing (September 1985); The Arkwood, Inc., Site covers approximately 20 acres on the Missouri-Pacific Cricket Railroad siding, south of Omaha in .Boone County, Arkansas. The site consists of a millwork shop, a wood-treating plant which used pentachlorophenol (PCP) and creosote, and a storage yard for the treated wood products before sale. The site owners started operations at the site in the early 1960s and formed an Arkansas corporation, Arkwood, Inc., shortly thereafter. In 1973, the owner of Arkwood, Inc., leased the process and land to Mass Merchandisers, Inc., of Harrison, Arkansas. Mass Merchandisers' lease expired on Jan. 1, 1985, and was not renewed. The plant has not operated since then. The history of waste disposal activities has been provided primarily by Mass Merchandisers. Wastes from the wood-treating operation were dumped into a cave at the plant from the beginning of the operation to around 1970. The entrance to the cave, which is at ground level, has been boarded and covered with a layer of dirt. Waste oils were also placed in a ditch adjacent to the railroad until approximately 1974, when the cost of the chemicals used in the process forced improvement of the recover5/ system and reduced the volume of wastes generated. Other wastes consist in part of the liguid from washing of the treatment roan floor and the treatment eguipment. These wastes accumulated in a tank and were then spread over the storage yard to control dust. Based on plant operations during 1970, a minimum of 6,000 to 7,000 pounds per year of waste were generated over the more than 20 years of operation, according to Mass Merchandisers. There is also a large pile of sawdust and wood chips in the southeast portion of the site. At least a portion of this pile is contaminated with PCP, according to tests conducted by the Arkansas Department of Pollution Control and Ecology. The State has detected PCP in local water wells, natural springs in the area, and nearby Walnut Creek. In 1982, Mass Merchandisers drilled a replacement well for a nearby resident, and retained a consulting firm to conduct a geohydrological study in the area. Approximately 660 persons depend on private wells within 3 miles of the site for drinking water. Status (April 1987); In May 1986, EPA signed an Administrative Order on Consent reguiring Mass Merchandisers to conduct a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action. A workplan submitted by the company in July 1986 has been approved by EPA. In August 1986, under the Arkansas Water and Air Pollution Control Act and the Remedial Action Trust Fund Act, the State filed suit against Mass Merchandisers and the former owner and operator of Arkwood for investigation and remedial action at the site. On-site field activities have been delayed because the land owner has refused to grant access to Mass Merchandisers.

(MOUNTAIN VIEW PLANT) ....... . .... Mountain View, California Conditions at listing (October 1984): Fairchild Camera & Instrument Corp. manufactures semiconductors at a plant in Mountain View, Santa Clara County, California. The facility occupies approximately 56 acres and is surrounded by residential and industrial areas. Monitoring wells on the site are contaminated with trichloroethylene, 1,1,1-trichloroethane, 1,1- and trans-l,2-dichloroethylene, according to analyses conducted by a consultant to Fairchild. Contamination is believed to have resulted from leaking underground solvent tanks. About 270,000 people depend on ground water within 3 miles of the site as a source of drinking water. Since early 1982, Fairchild has been investigating the site geology and hydrcgeolcgy and attempting to define the lateral and vertical extent of solvents underlying the site. Fairchild has installed two wells to pump and treat the contaminated ground water plume. Fairchild is working with the California Regional Water Quality Con- trol Board to further define the extent of contamination and outline various cleanup strategies. . The plant received Interim Status under the Resource Conservation and Recovery Act (RCRA) when the 'ccmpany filed Part A of a permit application. This is one of 19 sites in the South Pay Area of San Francisco. Facilities at these sites have used a variety of toxic chemicals, primarily chlorinated organic "solvents, which contaminate a common ground water basin. Although these sites are listed separately, EPA intends to apply an area- wide approach to the problem as well as take specific action as necessary. * Status (February 1986): Continuing efforts to determine the extent of ground water contamination, Fairchild has installed 101 monitoring wells. The two treatment wells are now in operation. The California Regional Water Duality Control Board has issued Waste Discharge Requirements to the ccmpany. The requirements are the board's legal mechanism for regulating activities at facilities under its jurisdiction. On Aug. 15, 1985, EPA issued a CERCLA Administrative Order on Consent to Fairchild Camera's Mountain View Plant,'as well as to Intel Corp.'s and Raytheon Corp.'s Mountain View Plants. The order calls for the three companies to conduct a joint remedial investigation/feasibility study of the area to determine the type and extent of contamination and identify alternatives for remedial action. This site remains in proposed status until EPA implements the appropriate elements of its final policy for placing RCRA-related sites on the NPL and then applies the policy to this site.

Stockton, California Conditions at listing (October 1984); Marley Cooling Tower Co. operates on a site adjacent to Franklin High School in Stockton, San Joaquin County, California. The company began operation at this location in 1942. From 1966 until 1982, the company used chromated copper arsenate to pressure treat wood for the purpose of fabricating cooling towers. Since 1982, acid copper chromate has been used in the wood-treating process.' Since 1966, rainwater run-off contaminated with arsenic, chromium, and copper has been discharged""to a 2-acre percolation pond. The sludge in the pond and soil on-site are heavily contaminated with arsenic, chromium, and copper. Two on-site monitoring wells are contaminated with chromium, according to analyses conducted by the company. No off-site ground water contamination has been detected to date. Marley is currently working with the California Department of Health Services and the California Regional Water duality Control Roard to develop a plan to determine the full extent of soil and ground water contamination.. The facility received Interim Status under the Resource Conservation and Recovery Act (RCRA) when the company filed Part A of a permit application. Status (February 1986); Marley Cooling Tower is scheduled to complete the initial phase of a remedial investigation in February 1986. Current data indicate that the primary source of soil and ground water contamination is a retort pit used in the wood-treatment process. The surface water run-off pond is a secondary source of current soil and ground water contamination on-site. The second phase of the remedial investigation will focus on further defining soil and ground water contamination. This site remains in proposed status until EPA implements the appropriate elements of its final policy for placing RCRA-related sites on the NPL and then applies the policy to this site. 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' . MCNTROSE CHEMICAL CORP. Torrance, California Conditions at listing (October 1984): Montrose Chemical Corp. manufactured the pesticide DOT on a 13-acre site in Torrance, Los Angeles County, California, from 1947 until 1982. The site is located in a light industrial/residential area. About 3,000 people live or work within 0.25 miles of the site. The company's operations included formulation, grinding, packaging, and distribution of the pesticide. According to analyses conducted by EPA, Montrose, and various State and local agencies, on- and off-site soils and surface water are contaminated with DOT. The major transport mechanisms identified were storm water run-off and aerial emissions. On May 6, 1983, EPA issued an Administrative Order under CERCLA section 106 requiring Montrose Chemical to cease all discharges of DOT and to initiate a. study to determine the nature and extent of contamina- tion. After a more detailed review of the-Montrose site, EPA determined that further work was necessary to characterize the site and evaluate alternatives. Therefore, EPA prepared a workplan for a remedial investi- gation/feasibility study (RI/FS). This second phase of investigation will assess all areas of contamination, both on- and off-site, and the possible impact on public health and the environment. Status (January 1986): In February 1985, Montrose installed a tem- porary asphalt cover over the site. EPA did not endorse this activity and does not consider it a permanent remedy. In the summer vof 1985, EPA conducted Part I of the RI. On-site sampling conducted during Part I indicates high levels of contamination at 77-foot depths in soil and in the shallow ground water. In October 1985, Montrose and EPA signed an Administrative Order under CSRCLA section 106 requiring Montrose to conduct Phase II of the RI. Phase II consists of off-site sampling of soil, sediments, and surface water, and sampling of ground water both on- and off-site. EPA is deferring final rulemaking on this site because it needs time to conduct additional air monitoring to support the site's score on the Hazard Ranking System, which EPA uses to assess the relative hazards of waste sites. The Montrose Chemical Corp. Site will remain in proposed status until a later rulemaking.

East Palo Alto, California Conditions at listing (October 1984); The Rhone-Poulenc, Inc./ Zoecon Corp. Site covers about 0.1 acres in East Palo Alto, Santa Clara County, California. It is surrounded by residential and industrial areas. Tne site was originally proposed for listing under the name "Zoecon Corp./Rhone-Poulenc, Inc." Rhone-Poulenc, Inc., the previous owner, manufactured pesticides containing arsenic at the plant. Zoecon Corp., which purchased the site in 1972, produces agricultural chemicals, but no contamination has thus far been traced to its operations. Monitoring wells on the site are contaminated with arsenic and other metals such as lead, cadmium, mercury, and selenium, according to analyses conducted by a consultant to Rhone-Poulenc. Contamination is believed to have resulted from leaking underground storage tanks. About 58,000 people depend on ground water within 3 miles of the site as a source of drinking water. Rhone-Poulenc is working with the California Regional Water Cuality Control Board (CRWOCB) to determine the extent of ground water contamination. CRWQCB issued a Cleanup and Abatement Order to the company-in December 1983. The plant has received part 8 of its application for a permit under the Resource Conservation and Recovery Act (RCRA). This is one of 19 sites in the South Bay Area of San Francisco. Facilities at these sites have used a variety of toxic chemicals, primarily chlorinated organic solvents, which contaminate a common ground water basin. Although these sites are listed separately, EPA intends to apply an area- wide approach to the problem as well as take specific action as necessary. Status (January 1986): . In response to the Cleanup and Abatement Order issued in December 1983, Zoecon and Rhone-Poulenc initiated action to determine the extent of contamination. The companies submitted a remedial action plan to the CRWQB in December 1984. The CRWQB is working with the companies to select and implement an appropriate remedial action plan. This site remains in proposed status until EPA implements the appropriate elements of its final policy for placing RCRA-related sites on the MPL and then applies the policy to this site.

Wood preservatives, including creosote and pent^chorophenol (PCP), were used and stored on-site during the poleyard's ope-raSions. Leaking tanks and stored treated poles have contaminated ground Water and soil with wood-treatment chemicals, as well as associated hexa-,hepta-, and octa-chlorodioxins and furans, according to analyses conducted by both the California Regional Water Quality Control Board (CRWQCB) and SCE. California Water Service Co. wells within 3 miles of the site supply drinking water to the City of Visalia, population 59,000. After sampling ground water and soil in May 1976, CRWQCB issued a Cleanup and Abatement Order requiring SCE to (1) abate discharge of treating fluids into the soil, (2) contain contaminated soil and"water on the property, (3) pump shallow ground water under the site before and during construction of an underground slurry wall around the site, (4) pump the lower confined aquifer to remove contamination, and (5) clean up contaminated shallow ground water off-site. In response to the order, SCE removed 2,300 cubic yards of grossly contaminated soil to an approved Class I disposal site. The remaining soil was not sampled after the cleanup. In 1977, a 60-foot-deep cement-bentonite slurry wall was constructed to slow lateral migration of the shallow aguifer. Currently, SCE is pumping the shallow wells, treating the water by carbon filtration, and discharging it into the city sewer system. SCE has been sampling monitoring wells, along with California Water Service Co. wells, on a quarterly basis. The results indicate that on-site monitoring wells contain up to 12 parts per million (pprn) PCP, and off-site monitoring wells contain up to 0.15 ppm PCP.

The California Regional Water Quality Control Board (CRWQCB) and Watkins-Johnson's consultant have detected organic chemicals, including trichloroethene, trichloroethane, tetrachloroethene, dichloroethene, and Freon in soil and ground water on the site. The contamination is apparently the result of improper handling of hazardous waste. Early in July 1986, the CRWQCB issued Waste Discharge Reguirements to the company. The reguirements are the CRWQCB's legal mechanism for regulating activities at facilities under its jurisdiction. Later in July, CRWQCB issued a Cleanuo and Abatement Order to the company. In response, Watkins-Johnson has begun an interim program to pump and treat contaminated ground water.

Compensation, and Uafatfity Act of 1990 I MARTIN MARIETTA (DENVER AEROSPACE) Waterton, Colorado The Martin Marietta Denver Aerospace plant covers approximately 5,200 acres near the tow of Waterton in southern Jefferson County, Colorado. Martin Marietta began operations at the plant in 1956 when it purchased the undeveloped property and constructed facilities for development of missiles and missile components for the U.S. Air Force. Martin Marietta currently owns the property and continues its aerospace manufacturing activities for the U.S. Air Force. In the early 1960s, the company began disposing of waste oils, hexa- valent chromium salts, volatile organic compounds, and other industrial wastes on the property in a number of ponds covering a few acres. . In 1979, the ponds stopped receiving wastes and in mid-1980 were filled and closed. Tests conducted by EPA in early 1985 intercepted a plume of ground water contaminated with chrcmiun and organic chemicals downgradient fron a former waste disposal area. The area is approximately 1.5 miles upgradient frcm a Denver municipal water treatment facility. The facility captures alluvial ground water and surface water moving from the inactive waste disposal areas. It provides up to 15 percent of the potable water danand of more than 1 million.people in the Denver metropolitan area. In March 1985, EPA issued a CERCLA 106 order that required Martin Marietta to begin a comprehensive program at the site, including installa- tion of monitoring wells and plans for contairment and treatment of contaminated ground water. In February 1985, che Colorado Department of Health issued an emergency order to the cotpany to monitor ground vater and to prepare a remedial action plan for surface vater and ground water drainages adjacent to an active waste handling unit on the facility. The unit now holds Interim Status under the Resource Conservation and Recovery Act (PCRA.) The inactive waste disposal site has never been regulated under RCRA and is over 1 mile from the active waste units currently subject to RCRA. Under EPA and State orders, the company is installing monitoring wells in the vicinity of the Denver water treatment facility and planning further site investigations, including ranote sensing. EPA and the State are reviewing preliminary designs submitted by the company for a system to punp out ground water and treat it.

A buffer zone was acquired in 1974, bringing the total to 6,550 acres. Major operations at the plant, which is owned by the U.S. Department of Energy (USDOE), include fabrication and assembly of plutonium, beryllium, and uranium, recovery of plutonium, and separation of and research on americium. Dow Chemical Co. operated the plant from inception until June 30, 1975, when Rockwell International Corp. assumed operation. Releases of plutonium and tritium have contributed to contaminated soils and sediments in surface water. USDOE has completed some remedial work such as capping and removing plutonium-contaminated soils and is improving liquid waste treatment systems to reduce discharge of liquid effluents, which are covered by a permit under the National Pollutant Elimination Discharge System. Three evaporation ponds have contributed to nitrate contamination of ground water. These ponds may be covered under the Resource Conservation and Recovery Act. Approximately 80,000 people live within 3 miles of the facility. Status (July 1985): USDOE continues to conduct remedial work by removing hot spots of contamination. A recent court settlement requires USDOE to conduct remedial activities on private land east of the plant as a condition of its sale to local governments. USDOE has begun to address the site through its internal cleanup program. The installation assessment phase is underway.

(NSMP), which covers 3.5 acres on Nutmeg Valley Road in the western potion of Wolcott (population, 13,000) and 0.25 miles northeast of Waterbury (population 103,800). The area around the site is both rural residential and light industrial, with a number of other metal-working and metal-finishing shops in the immediate vicinity, including Waterbury Heat Treating Corp. (WHTC) and Alpine Electronic Components, Inc. (AEC). WHTC is 300 feet to the northwest of NSMP and performs various heat-treating operations (annealing and hardening) on metal articles. AEC leases a portion of the NSMP building in which it machines metal parts and performs degreasing, polishing, acid dipping, and assembly functions. NSMP is a small (8-30 employees) metal-working and machine shop that has been in business since 1951. Substances used in the machining processes include a kerosene-like cutting oil, machine lubrication oils, and carbon tetrachloride (for cleaning and degreasing). Carbon tetra- chloride and cutting oils were dumped onto the ground at an estimated rate of up to 15 gallons per day, according to the Connecticut Department of Environmental Protection (CT DEP). This practice was followed for between 14 and 20 years, ceasing by 1980. Soil adjacent to the shop building contains volatile organic chemicals and metals, including lead and copper, according to analyses conducted by EPA. No contamination was detected in water and sediment in Old Tannery Brook 300 feet from the site. -A fresh-water wetland is approximately 600 feet downstream from the site. Local surficial deposits, primarily sand and gravel, are relatively permeable, facilitating movement of contaminants into ground water. About 10,500 people draw drinking water from private wells within 3 miles of the site. EPA has conducted preliminary assessments at all three companies and site, inspections at NSMP and WHTC. Further investigation is required to more fully define the quantities of contaminants present in the soil and to evaluate the underlying ground water.

Cheswold, Delaware Chertv-Solv, Inc., started a small solvent distillation facility in 1982 on a 1.5-acre site in Cheswold, Kent County, Delaware. The company recycled waste solvents by placing a drum on an electric coil heater, which distilled the solvents into a second drum. The contents of the second drum were filtered into a third drum, which was returned to the customer. The residues remaining after distillation were classified as hazardous waste under Subtitle C of the Resource Conservation and Recovery Act (RCRA) and were stored on-site. On September 7, 1984, an explosion and fire at the site destroyed the entire distillation facility. At the time, witnesses observed fluids flowing off a concrete pad into the soil. On September 21, 1984 and again on January 31, 1985, the Delaware Department of Natural Resources and Environmental Control (DNREC) issued orders under State law calling on the company to cease operations immediately, monitor ground water, and remove all contaminated soil. The company failed to take any action. Subsequent analyses conducted by DNREC detected hiqh concentrations- of organic chemicals,, including trichloroethylene, 1,1,1-trichloroethane, and 1,1-dichloroethane, in soils and qround water on and off the site. Both the upper and lower zones of the Columbia aquifer are contaminated. About 5,500 residents are served by private wells within 3 miles of the site. In September 1985, DNREC excavated contaminated soil and began using a treatment process that passes air through the soil to remove the volatile' organic contaminants. The air-stripping process should reduce contamination to levels that permit returning the soil to the excavated area. Later in the year, DNREC plans to install an air-stripping system to remove volatile organic contaminants fro'u ground water. DNREC has filed suit against Chem-Solv to recover the money it has spent. The company has declarer] itself financially insolvent. In 1984 and 1985, the State issued two orders requiring Chem-Solv to begin remedial action at the site. The company refused to ccmply. When Chem-Solv started operations, it filed Part A of a permit application under RCR\, giving the company Interim Status as a storage facility. On August 6, .1985, DNREC made a final decision to deny Chem-Solv the storage permit. Because Chem-Solv, Inc., has lost Interim Status (and hence authorination to operate) and there are additional indications that the owner or operator will be unwilling to undertake corrective action, it meets the second component of EPA's policy for listing RCRA-related sites.

It currently is the base of operation for..the 436th Military Airlift Wing. The base's operations generated numerous wastes, including paints, solvents, and oil. Some wastes were buried in drums, while others were disposed of through the storm drainage system. The wastes were disposed of in various on-base locations totaling 44 acres. Ground water on the site is contaminated with arsenic and other metals, and an on-site stream is contaminated with trichloroethylene, according to tests conducted by the Air Force. The base well system serves about 10,000 people and is routinely monitored by the Air Force. Currently, it is free of the contaminants found in the ground water. Dover Air Force Base is participating in the Installation Restoration . Program (IRP), the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past hazardous waste sites and controlling the migration of hazardous contaminants from these sites. The Air Force has completed Phase I (record search). Phase II (hydrogeological investigation) is underway. Status (April 1987); Approximately 11 areas on the base have now been identified as potential sources of contamination. The Air Force is working with the State to close the industrial wash basins, one of the major sources of ground water contamination at the base, according to requirements of the Resource Conservation and Recovery Act (RCRA). The Air Force filed Part A of a permit application for the basin, giving it Interim Status under RCRA. Phase II of the IRP is still underway. This site is being reproposed to be consistent with EPA's recently proposed policy for placing on the NPL sites located on Federally-owned facilities that are subject to the corrective action authorities of Subtitle C of the Resource Conservation and Recovery Act. EPA is soliciting comments on the Hazard Ranking System score for the site, which includes areas subject to RCRA Subtitle C corrective action authorities.

Dover, Delaware Dover Gas Light Co. operated a coal gasification plant on a 0.9- acre site in Dover, Kent County, Delaware, from 1859 to 1948. The plant processed coal to produce a gas that was piped to street lamps in Dover. When the plant closed, the structures, except for a brick garage, were ' demolished. Steel and iron scrap were removed; all other materials, including coal oil, coal tar, coke, and an unknown kind of acid, were buried on the site. In 1984, during geotechnical studies of the property prior to construction of the new Kent County Family Courthouse, remains of this coal gasification plant were discovered buried on site. The buried materials include coal tar residues containing hazardous substances. The Delaware Department of Natural Resources and Environmental Control (DNREC) installed and sampled 16 monitoring wells to determine the nature and extent of contamination. The results show that hazardous substances buried on site have been released to ground water. These substances include benzene, toluene, xylene, lead, trans-1,2-dichloroethylene, and polynuclear aromatic hydrocarbon compounds. DNREC determined that these substances are in ground water at depths of up to 53 feet and a horizontal distance of at least 300 feet southeast of the site. The closest supply well, 1,000 feet southwest of the site, draws on the Cheswold aguifer. It is part of Dover's municipal water system.

Before it was a landfill, the U.S. Army Corps of Engineers used the site for disposal of dredge soils from the Delaware and Christiana Rivers. New Castle County operated the site from 1968 through 1981. In 1981, the Delaware Solid Waste Authority (DSWA) took control of site operations. Thereafter, it was permitted by the State to accept municipal wastes. Operations stopped and the site was closed in November 1985. During closure, the site was covered with a 2-foot clay cap and seeded. Before 1980, according to the Delaware Department of Natural Resources and Environmental Control, wastes disposed at the unlined landfill included paint sludges, metal sludges, petroleum refinery wastes, polyvinyl chloride wastes, chemical process wastes, and phenol resins. In 1984-85, a consultant to DSWA detected arsenic, benzene, ethylbenzene, and tetrachloroethylene in on-site monitoring wells. Aguifers of both the Columbia and Potomac- Formations are at risk. The Artesian Water Co. has nine walls within 3 miles of the site. The water is blended with water from other wells. The public water supply for 150,000 people is potentially affected. U S.

Later, Tyler excavated the pit to about 20 feet, filled it in, capped it with 6 inches of top soil and clay, and planted vegetation. The site is now occupied by Metal Masters, which manufactures commercial kitchen equipment. In 1982, EPA detected elevated levels of toluene, ],1-dichloroethane, and ],],]-trichloroethane in on-site soils. Since 1977, TCE has been detected in Smyrna municipal wells. To remove contamination from the wells, the town improved the efficiency of its air stripping process and added an activated carbon filtration unit to its water treatment system. The contamination in Smyrna's wells has significantly declined, and the treatment system continues in operation. According to the Delaware Department of Natural Resources .and - Environmental Control, the Tyler pit is a likely contributor to the contamination of Smyrna's wells, although there may be other sources. About 6,700 people depend on wells, both municipal and private, within 3 miles of the site for their drinking water.

From 1971 to mid-August 1983, the company operated'a recycling and transferring facility on the site, handling a wide variety of chlorinated and nonchlorinated organic solvents, paint/varnish wastes, acid and alkaline plating wastes, PCBs, and waste ink. According to tests conducted by EPA, ground water, soils, and sediments are contaminated with heavy metals and volatile organic compounds. The company abandoned the operation in mid-1983, informing the State that it lacked resources to continue operations and leaving approximately 1,200 drums and 12,000 gallons of unknown liquids and sludges in large holding tanks. In August 1983, the State funded and oversaw a cleanup of the site by a contractor. In the cleanup, 41 tons of drums were crushed and removed and 65 truck and tanker loads of contaminants were disposed of properly. The cost was $950,000. In February 1984,.EPA issued an Administrative Order under CERCIA requiring City Industries to clean sludge frcm holding tanks, remove contami- nated soils, and treat contaminated ground water. The order was not complied with. In March through May 1984, using about $500,000 of CER.LCA emergency funds, EPA emptied, cut open, and cleaned the holding tanks, thus removing the threat of explosion and further soil contamination. EPA's emergency team and its contractors used an incineration device to treat about 1,700 tons of contaminated soil. The treated soil remains on the site. In February 1984, the State filed a civil complaint against the landowner, operator, and four companies associated with the operator. On April 24, 1984, the State held a meeting attended by generators potentially responsible for wastes associated with the site. The, facility received Interim Status under the Resource Conservation and Recovery Act (RCRA) when the company filed Part A of a permit application. The company filed Part B, but EPA denied the application twice because the company did not meet the financial guarantee and waste analysis requirements of RCRA. The company also failed to submit a closure plan. Status (April 1987): The generators formed a steering committee comprising approximately 200 industries. It has worked with the State during a remedial investigation of ground water contamination. EPA is reviewing data from this investigation. In August 1986, EPA issued demand letters to approximately 250 potentially responsible parties to recover Federal money spent for the 1984 emergency action.

Hollister, Florida Conditions at listing (October 1984): Montco Research Products, Inc., manufactures chemical intermediates and purifies organic compounds for commercial use on a ID-acre site in Hollister, Putnam County, Florida. The processes generate discharge cooling water and distillation residues. The State has confirmed that both soil and ground water at the site are contaminated with lead, arsenic, cyanide, chromium, benzene, and several other organic chemicals. An estimated 270 people draw drinking water from wells within 3 miles of the site. The State and the site owner are awaiting a civil, court ruling on access. The State is conducting further negotiations outside of court. EPA has taken administrative enforcement action against the company for failing to respond promptly to a request for information under section 3007 of the Resource Conservation and Recovery Act (RCRA). Status (January 1986): In a State court decision in June 1985, the court authorized access to the State for the limited purpose of conducting a pollution assessment, but denied access for the purpose of removing any materials except samples related to that assessment. In July 1985, EPA issued a unilateral Administrative Order under CERCLA section 106 for immediate removal of contaminated soils and sludges on- site. This order has not been complied with. An administrative hearing between EPA and tMontco has been held on the subject of the company's failure to respond to the request for information under RCRA section 3007. No decision has been issued yet. EPA is deferring final rulemaking on this site because it needs more time to analyze the comments received during the public comment period.

Piper assembles and paints light aircraft at the southern end of the Vero Beach Municipal Airport. In 1980, an unknown amount of trichloroethylene leaked from an underground storage tank and distribution system, contaminating a nearby municipal well of the Vero Beach Water & Sewer Department with volatile organic compounds (VOCs). The well, which was subsequently shut down, was part of a municipal system serving about 33,000 people. Six months later the city developed two other wells to replace the closed one. In 1981, the State took an enforcement action requiring Piper Aircraft to conduct a monitoring, testing, and treatment program at the site. Piper repaired the leaking storage tank and in April 1981 began to pump out the contaminated ground water. To date, the pumping has yielded approximately 2,050 gallons of VOCs, including trichloroethylene, cis-trans-l,2-dichloro- ethylene, vinyl chloride, and 1,1-dichloroethylene. The contaminated water is sprayed into the air to enhance removal of VOCs and is discharged into the Main Canal leading to the Indian River. Status (September 1986); The city is continuing to submit quarterly reports on the monitoring of the treated effluent.being discharged to the Indian River.

West Palm Beach, Florida Conditions at listing (October 1984); The Pratt & Whitney Aircraft/ United Technologies Corp. Site comprises about 7,000 acres in West Palm Beach in north central Palm Beach County, Florida. Jet engines have been manufactured and tested on the site since 1957. Pratt & Whitney is a privately-owned Canadian-based operation and a division of United Technologies Corp. On the site are a sanitary landfill where solvents were disposed of, a solvent storage tank that leaked approximately 2,000 gallons of tri- chloroethane through an underground valve, a solvent distilling area, and jet fuel heaters which contained PCBs until the mid-1970s. Ground water and surface water are contaminated with PCBs and organic solvents, according to tests conducted by Pratt & Whitney. The company also found that the well serving its 7,200 employees is contaminated with solvents. Pratt & Whitney has installed a forced aeration system to remove volatile organic chemicals (VOCs) from its well fields and is involved in discussions with the State regarding PCBs and landfill remedial actions. Status (January 1986); On April 26, 1985, the company signed a Consent Agreement with the State under which the company is to implement a State-approved remedial action plan to deal with VOCs and PCBs. Other areas of contamination, including PCB-contaminated soil and a buried leaking waste oil tank containinq VOCs, have been discovered on the property. Voluntary cleanup of the site is continuing. The Pratt & Whitney facility was first proposed for the NPL as part of Update #2. In response to public comments received, EPA completely reevaluated the site and made' a significant change in its score on the Hazard Ranking System, which EPA uses to assess waste sites for the NPL. Conseguently, EPA reproposed the Pratt & Whitney facility on Sept. 18, 1985 (50 FR 37950) as part of NPL Update #4 and solicited comments on the revised score.

The ponds are part of an old 1,700-acre phosphate strip mine and were used for storing and dewatering waste clays and tailings from phosphate ore processing. The Hillsborough County Division of Public Utilities leases the land from American Cyanamid Co. and used two on-site ponds from 1974 to 1982. The larger pond (1.5 acres) received primarily septic sludge and the smaller pond (0.6 acres) received the grease trappings fron commercial restaurants, industrial cutting oil, and other types of waste oil. The total volume of wastes in both pits is over 6,000 cubic yards. Tests conducted by EPA in 1979 found arsenic and lead in.the septic sludge pond and 1,1,1-trichloroethane and toluene in the oil pond. EPA also detected 1,1-dichloroethane, 1,1-dichloroethene, toluene, and benzene in ground water that forms the secondary artesian aquifer developed in the Hawthorne Formation. Over 4,000 persons draw water from wells into this aquifer within 3 miles of the site. Turkey Creek is contaminated with cadmium, chromium, lead, and zinc, according to EPA. The creek is about 0.5 miles to the east of the site. The county is working with consultants to determine the best method for cleaning up the site. The county has constructed an under- ground slurry wall around the ponds to prevent contaminants from escaping and ground water from entering. Also, the county is pumping out the contaninated ground water within the wall, treating it, and spraying the treated water onto the ground. Incineration of sludges in the pond is scheduled to get underway shortly.

The site is on a hill on a 20-acre parcel of laqicl, of which only 5 acres were used for waste disposal. The privately- owned'.-landfill operated from. 1974 to 1980. It had a permit from the Georgia Environmental Protection Division to accept nonhazardous wastes. Sometime after'1980, the landfill was abandoned. Residues from herbicide manufacturing and latex waste from the carpet-manufacturing industry were buried in unlined trenches. According to records obtained from Velsicol Chemical Corp.'s plant in Chattanooga, Tennessee, the wastes contained arsenic and organic chemicals, including benzonitrile and herbicides. About 3,000 tons of hazardous waste were buried during the operational period. ' The site is located in the outcrop of the Knox Group in the Valley ' and'Ridge Geologic Province. The soil is permeable, thus facilitating movement of contaminants into ground water, which is at 40 feet. The Kensington Water and Sewer Authority provides drinking water to an estimated 4,300 people from wells 1.5 miles south of. the site. A private well is 1,900 feet from the site. Surface water within 3 miles downstream of the wastes is used for fishing and irrigation.

(AREAS 1,2, & 4) Augusta, Georgia Conditions at listing (September 1983): 01 in Corp.'s plant in Augusta, Richmond County, Georgia, manufactures chlorine and caustic soda, generating a mercury-contaminated brine sludge in the process. Since the early 1970s, Olin has disposed of the sludge in two unlined disposal pits and in a lined surface impoundment (Areas 1,2,and 4). The liner in the impoundment may have been damaged by dumping of construction rubble. About 32,000 tons of mercury-contaminated wastes have been disposed of in the three areas. All three areas, plus a retort ash and filter cake dump, occupy about 5 acres on the southern portion of the plant property. In April and July 1981, the company's on-site monitoring wells near the disposal facilities detected mercury in ground water. Within 3 miles of the disposal areas are 11 Richmond County drinking water wells. More than 10,000 people use ground water in this area. Large areas of fresh-water wetlands are within. 1.5 miles of: the Olin plant. The plant acquired Interim Status under the Resource.Conservation and Recovery Act (RCRA) when the company filed Part A of a permit appli- cation.. Status (June 1984): A State Consent Order executed in January 1984, required Olin to cease waste disposal in the two pits and to retain a consultant to fully define the extent of contamination. The ccmpany submitted the resulting Groundwater Assessment Program Report to the State, where it is currently under review. EPA is deferring rulemaking on this site because appropriate scoring documents were not in the public docket and so were not available during the comment period. Thus, EPA is providing an additional comment period for this site. Status (January 1986); In May 1985, the State issued an order requiring Olin to submit a corrective action plan for all releases into the environment from all disposal units at the site. Olin appealed the order and in December 1985 the State agreed to rescind it. Then the State required Olin to meet the January 1984 order calling for the closing of Pits 3 and 4. However, the State required no further corrective action beyond that, and EPA is currently assessing the State-Olin agreement for consistency with RCRA requirements. EPA called in Part B of the RCRA permit application in August 1985. EPA certified that the ccmpany is in compliance with the financial requirements and ground water monitoring requirements of RCRA.

JAAP is divided into two major functional areas: the Manufacturing Area, which was proposed for the NPL in October 1984, and the Load-Assembly-Packing Area (LAP Area). This NPL site consists of the LAP Area, which covers about 22 square miles of JAAP east of Illinois State Highway 53. During its operating life (the early 1940s to 1977), high explosive artillery projectiles, aerial bombs, and a variety of ammunition component items were loaded, assembled, and packaged. Other activities included testing of ammunition, washout and renovation of projectiles, and burning and demolition of explosives. Since 1977, JAAP has been maintained in nonoperating standby condition by the contractor/operator (Uniroyal, Inc.) JAAP is participating in the Installation Restoration Program (IRP), the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past hazardous waste sites and controlling migration of hazardous contaminants from these sites. As part of this program, the Army has documented releases into ground water and surface water of munitions-related contaminantsincluding trinitrotolulene (TNT), dinitrotoluene and heavy metalsattributable to production activities in the LAP Area. The main source of waste water from this area was "pink water" resulting from washout of rejected bombs and from washing of equipment and floors. Munitions-related contaminants have been found in monitoring wells located near a former leaching pond in the washout facility.

About 15,000 people live within 3 miles of the site. < In 1931, Lindsay Light & Chemical Co. established a mill in West Chicago for the extraction of thorium and nonradioactive elements frcm monazite and other ores. Later, the site was used for the manufacture of gaslight mantles (which contain thoriun), mesothoriun, and, during World War II, hydrofluoric acid. Ownership of the facility changed from Lindsay to American Potash & Chemical in 1958 and to Kerr-McGee Chemical Corp. in 1967.. Operations at the site continued until 1973, when Kerr-McGee, the current cwner, closed the plant. The original sewage treatment plant was built in 1919 and included two septic tanks. Over the years, the plant changed, and the tanks were filled with radioactive materials. In addition, fill, including radio- active materials, was placed in other areas of the site, while modernizing the plant, the city has located many surface and subsurface areas of contamination. To allow the modernization to continue,-any areas that obstruct construction are expected to be excavated and the material placed in a designed storage area on the site. --_ Status (January 1986); Because of an administrative error during the public conment period, EPA is extending the comment period on this site for an additional 60 days.

Landfill Management owns the site and started landfilling in December 1971 and is still in business. The site is adjacent to the Envirochem Corp. Site, which was placed on the NPL in September 1983. In ]971, the north side of the area was licensed by both Marion County and the State for disposal of solid wastes. A 100-foot strip of land was excavated to depths of 3 to 6 feet. The loose dirt was piled on a 50-foot strip of land immediately south of the excavated area for use later as cover material. After the first excavated area was filled by alternate dumping of refuse and covering with a layer of dirt, a second area was excavated ]50 feet south of the first one. After these areas were filled, the land between the two was excavated. More than 4 million cubic yards of waste have been buried at the landfill, according to estimates made by the U.S. Geological Survey. The wastes include coal tar, asbestos insulation, iron oxide sludge, paint waste, and clarifier sludge. Metals, including arsenic, chromium, cadmium, and nickel, are present in ground water, according to analyses conducted by EPA. The landfill lies above a continuous shallow sand and gravel deposit along White River, Fall Creek and Eagle Creek. About 6,100 people depend on private wells drawing on the shallow deposit. The area has been described by several sources, including the Indiana State Board of Health, as having the greatest potential for ground water development (in terms of well yield) of any area in Marion County. Eagle Creek is contaminated with metal compounds (aluminum, lead, and zinc), according to tests conducted by EPA. The creek is used for fishing and boating. All of White River and Eagle Creek are a potential habitat for the Indiana bat, a species designated as endangered by the U.S. Fish and Wildlife Service. The landfill continues to operate as a solid waste disposal facility under a State permit.

South Hope, Maine Conditions at listing (April 1985); Union Chemical Co., Inc., operated a chemical recycling and incineration business from 1978 to 1984 on a 0.75-acre fenced lot in South Hope, Knox County, Maine. The site is bounded on the east by Quiggle Brook and is in the 100-year floodplain. Grassy Bond, an alternate drinking water source for the towns of Camden, Rockport, Rockland, and Thomaston (approximately 22,800 people), is located less than 1 mile downgradient. The site once contained approximately 2,500'drums and over 30 tanks holding 100,000 gallons of flammable materials and sludges. Among the wastes were PCBs, methylene chloride, cyanides, methyl ethyl ketone, and trichloroethene. An on-site well and Quiggle Brook are contaminated with trichloroethylene, according to tests conducted by the Maine Department of Environmental Protection and EPA. Union Chemical lost Interim Status in June 1984 under Maine's Uncontrolled Hazardous Substance Act because it failed to satisfy requirements of the Resource Conservation and Recovery Act (RCRA).' Under section 3008 .of RCRA, EPA fined the company for failure to submit, a complete Part B permit application. Using CERCLA emergency funds, EPA removed all surface drums, over 100,000 gallons of liquid wastes and sludges from above-ground storage tanks, and some contaminated soil from the site. The action was completed on Oct. 8, 1984. Status (April 1987): EPA is considering various alternatives for this site.

Until 1971, Edgewood Area operated as a distinct military entity known as the Edgewood Arsenal. The primary mission of the Arsenal, and subseguently the Edgewood Area of APG, has been developing and testing of chemical agent munitions. According to an Army Installation Assessment report (1976): "From 1917 to the present, the Edgewood Area has conducted chemical research programs, manufactured chemical agents, and tested, stored and disposed of toxic materials. As a result of these extensive programs, the Edgewood Area has large areas of land and water, and numerous buildings, which are contaminated or suspected of contamination." A "contamination map" and discussion in the report indicate "contaminated or potentially contaminated" areas in virtually every land portion of the Edgewood Area. Among the substances disposed of in the Edgewood Area are significant guantities of napalm, white phosphorus, chemical agents, and nerve agents. Several of the chemical agents, which include arsenic and cyanide, are suffi- ciently toxic and.persistent to present a danger for months or even years. APG is participating in the Installation Restoration Program (IRP), the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past hazardous waste sites and controlling the migration of hazardous constituents from these sites. As part of the IRP, the Army conducted an environmental monitoring program at Edgewood Area in 1977 and 1978 covering "0" Field, Canal Creek, "J" Field, Graces Quarters, and Carroll Island. Evidence was found of substantial contamination of surface water and ground water in the vicinity of Old "0" Field, which includes a wetlands area that is a designated habitat for bald eagles. In February 1984, the State recommended that four Edgewood .Area standby water-supply wells in the Canal Creek area be immediately removed from service because of high levels of volatile orqanic chemicals detected during routine testing in late 1983. These wells serve a resident population of about 3,000 persons. Also within 3 miles of the facility are the Long Bar Harbor well field of the Harford County Department of Public Works and the well field used by the Joppatowne Sanitary Subdistrict. About 35,000 persons are served by these two well fields; an alternate water source is available. The Army is continuing to monitor surface water and ground water at several locations within Edgewood Area and has undertaken a detailed hydrogeological study in the vicinity of the Old "0" Field. The facility acguired Interim Status under the Resource Conservation and Recovery Act when the Army filed Part A of a permit application. Status (September 1985); IRP activities continue.

It is an active Army test and evaluation installation primarily responsible for planning and testing of weapons, munitions, vehicles, and various equipment. APG consists of two functional areas: The Edgewood Area (13,000 land acres, including Gunpowder Neck, Pooles Island, Carroll Island, and Graces Quarters) and the Aberdeen Area (17,000 land acres). The land portions of the two areas are separated by Bush River. The Aberdeen Area is bordered on the west by the Bush River and northeast to south by the Chesapeake Bay. The area is drained by seven creeks plus the Bush River. Most of these creeks have their headwaters on the Aberdeen Area. The area contains firing ranges, impact areas, vehicle test racks, and laboratories-in support of the testing activities. The location of concern on the Aberdeen Area is the 20-acre Michaelsville Landfill. The Army has detected lead, mercury, chromium, benzene, and cadmium in ground water on the site. Other potentially hazardous portions of the Aberdeen Area are currently being evaluated. APG is participating in the Installation Restoration Program (IRP), the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past hazardous waste sites and controlling the migration of hazardous constituents from these sites. As part of the IRP, the Army has performed an environmental contamination survey and assessment of the Aberdeen Area and is monitoring ground water and surface water in the areas of suspected contamination. APG is cooperating with the State of Maryland Department of Hygiene and Mental Health in determining the extent of the Aberdeen Area contamination. The facility acquired Interim Status under the Resource Conservation and Recovery Act when the Army filed Part A of a permit application. Status (September 1935): IRP activities continue.

This company has cleaned, brightened, anodized, and sealed aluminum parts for the automotive industry on the site since 1962 and has owned the property since then. The company disposes of process and cooling water in a 7-foot deep unlined seepage lagoon measuring 207 feet x 60 feet. The lagoon holds an estimated 2,400 cubic yards of waste. According to analyses conducted by EPA, the water placed in the lagoon contains nitric acid and chromium. The potential for ground water contamination is high because the subsurface consists of highly permeable glacial drift, mainly sand and gravel, and because wastes can easily enter the ground water from the unlined lagoon. The glacial drift aquifer underlying American Anodco, . Inc., supplies public and private wells within 3 miles of the site which serve over ]0,000 people. EPA detected low levels of arsenic in Prairie Creek, which is near the site. Grand River, which is within 3 miles of the site, is used for fishing and recreation.

The company recycled drums on the property, which it leased from the Chesapeake and Ohio Railway Co. from 1964 to 1981. Barrels, Inc., allegedly dumped waste residues from drums directly onto the ground as an initial step in recycling drums. According to tests conducted by the Michigan Department of Natural Resources (riDNR) in 1983, shallow ground water is contaminated with lead and zinc. The shallow contaminated aquifer is hydraulically connected to the deeper Saginaw Formation, so that water can move between then. Tne shallow and deeper aquifers provide drinking water to the 133,000 residents of Lansing and Holt via municipal wells within 3 miles of the site. The nearest well is 800 feet away. The nearest downslope surface water, Grand River, is 1,800 feet from the site. The Grand River, which is a fishing stream, is potentially threatened by conditions at the site. The areas along the river are a habitat for the Indiana bat, designated by the U.S. Fish and Wildlife Service as an endangered species. In January 1986, MDNR gained access to the site from a State Court. MDNR has approved $449,589 under the Michigan Environmental Response Act for removal and disposal of barrels, debris, contaminated soil, and buried tanks. All drums, 1,001 yards of visibly contaminated soil, and nine underground tanks have been removed and sent to an approved hazardous waste disposal facility. The contents of one underground tank and two tanks in the building have been pumped out. Activities remaining include: removal of additional soil, crushed drums, resins, nonhazardous and hazardous liquids, nonhazardous solids, and additional buried tanks.

Problems at this site date;to 1961, when the State found that a private well was contaminated with thiocyanate. Subsequently, Cu Pont supplied water to a limited number of residents. The contamination apparently results from a waste pile on the site, as well as occasional spills during routine operations. Du Pont installed two interceptor wells that pump the contaminated water to a treatment plant. The extent of off-site contamination is unknown. About 4,000 people depend on wells within 3 miles of the site as a source of drinking water. The plant received Interim Status under the Resource Conservation and Recovery Act (RCRA) when the company filed Part A of a permit application.

From 1965 to 1969^ the site operated as a sanitary landfill and was also licensed by the? State to accept industrial waste. Muck was excavated to a depth of 4?to' 10 feet, and the area was filled in with waste; 99 percent of the waste was foundry sand and the rest was construction debris. The water table is 2 feet below the surface. According to the original owner, Waste Management of Michigan, Inc., owned and operated the s/ite from 1969 to 1972 under the name Industrial Disposal. Again, foundry sand, which contains iron, was accepted. In 1972, the original owner bought back the property, closed the landfill, and covered it with foundry sand. Since then, Bergsma Pallet Co., a wood pallet business, has occupied the site. In June 1984, EPA took sediment samples in a drainage ditch that originates in the northwest portion of the landfill. On-site samples, as well as downstream off-site samples, contain high levels of semivolatile compounds and heavy metals. The ditch drains into Indian Mill Creek at the south end of- the fill, via an unnamed creek and drainage pipe. Indian Mill Creek flows into the Grand River. The site is in a river valley directly north of the city limits of Grand Rapids. About 3,600 people draw drinking water from private wells within 3 miles of the site. One well is on the site. During the summer, the Grand Rapids Water Department, which serves 235,000 people, draws water from the Grand River 1.7 miles downstream of the site.

The present owners are Ford Motor and the Wayne County Road Commission, which operates the Willow Run Airport. The abandoned lagoon is on airport property. Ford Motor disposed of approximately 1 million cubic feet of sludge in the lagoon, according to information the commission provided to EPA as required by CERCLA section 103(c). Analysis of the sludge conducted in 1979 by the Michigan Department of Natural Resources detected PCBs and heavy metals, including lead, cadmium, and mercury. A noncontinous sand and gravel aquifer underlies the area at a depth of 65 to 100 feet. An estimated 60,000 people draw drinking water from municipal wells within 3 miles of the site. Private wells are also in the area, the nearest about 2,000 feet from the si'te. The nearest downslope surface water, Willow Creek, is 800 feet from the site. It is potentially threatened because the lagoon is unlined and had no structures to divert run-off. Belleville Lake, 3,600 feet from the site, is used for recreation.

Until February 1977, the plant also manufactured hexachlorocyclopentadiene, a toxic chemical used in the production of pesticides. The plant has been inactive since 1982, and there are no plans to reactivate it. About 506,000 cubic yards of organic wastes were improperly disposed of on 50 of the 900 acres. The disposal has contaminated ground water and surface water on and off the site with chlorinated organic chemicals, according to tests conducted by EPA. A shallow aauifer below the site supplies drinking water to about 700 people. There is no altern- ative drinking water source. On Feb. 21, 1979, the State filed suit against Hooker to compel cleanup of the site. Pursuant to a consent judgment, Hooker removed most of the waste on the surface in 1981 and 1982 and disposed of it properly. Since 1979, Hooker has -been pumping and treating ground water with carbon to prevent contamination from migrating off-site. The site is an inactive portion of a facility that acguired Interim Status for a small barrel storage area under the Resource Conservation and Recovery Act when Hooker filed Part A of a permit application. Hooker has now decided to close the storage area instead of seeking an operating permit.

Kansas City, Missouri Conditions at listing (April 1985); The Conservation Chemical Co. (CCC) Site covers approximately 6 acres in Kansas City, Jackson County, Missouri. It is on the south bank of the Missouri River near where the Blue and Missouri Rivers meet. CCC operated a waste treatment and disposal facility on the site from 1960 to 1980. The primary wastes handled were metal-finishing wastes, including pickle liquors, spent plating solutions, heat-treating materials, and alkaline cyanides; chlorinated and nonchlorinated solvents and other organics; alkaline refinery wastes; laboratory chemicals; and wastes containing arsenic and elemental phosphorus. Approximately 300,000 tons of wastes were accepted for treatment and disposal. Some wastes were incinerated, but most were buried in lagoons which were either unlined or inadequately lined to contain the wastes. CCC attempted physical stabilization of the lagoons by mixing the lagoon contents with fly ash and waste pickle liquor. The lagoons were then covered with soil. CCC obtained Interim Status for various storage tanks under the Resource Conservation and Recovery Act (RCRA) by filing Part A of a permit application. Subsequently, those wastes were disposed of off-site, and the tanks are no longer used. Technically, the facility has Interim Status until it is properly closed. EPA investigations of the site and surrounding areas have detected various hazardous substances in surface soil, and ground water downgradient of the site is contaminated with numerous metals, organic compounds, and other pollutants. This ground water is part of an aquifer that is used locally as a drinking and industrial water supply. Because the ground water and the Missouri River are hydraulically connected, contaminants in the ground water are entering the Missouri River, which is used locally and regionally for recreation, industry, irrigation, and municipal water supply. On Nov. 22, 1982, the United States filed a civil action under RCRA and CERCLA seeking a court-ordered site cleanup and reimbursement of the government's investigative costs. The parties sued were CCC, its president and principal stockholder, Conservation Chemical Co. of Illinois (a related corporation), and four major contributors of waste to the site: Armco, Inc., FMC Corp., IBM Corp., and AT&T Technologies, Inc. (formerly Western Electric). On June 19, 1984, the four original generator defendants filed third-party suits against 152 other generators, 7 Federal agencies, and 16 insurance .companies. On Oct. 1, 1984, 77 additional third-party defendants were added to the lawsuit.

The Findett facility covers about 3 acres; however, contamination originating at the facility may cover a much greater area. A municipal well field is within 1 mile of the .site. Among other, activities, Findett reprocessed fluids containing PCBs between 1963 and 1974. Some wastes from the reprocessing were disposed of in a small pond on the Findett property. In 1977, after significant levels of PCBs were detected in the pond, Findett excavated and back- filled a portion of the pond. In 1979, EPA conducted further investigations at the site, which showed that the pond area was again contaminated with PCBs. In 1980, as a result of these investigations, EPA issued an Administrative Order under the Clean Water Act requiring further excavation of the pond area. Additional sampling under the 1980 order indicated PCBs had migrated beyond the immediate pond area and into subsurface areas. The facility received Interim Status under the Resource Conservation and Recovery Act (RCRA) when the company filed Part A of a permit appli- cation for treating and storing hazardous waste. EPA issued an Administrative Order under section 3013 of RCRA in the summer of 1982. The order required Findett to design and implement a monitoring, sampling,, and analysis plan to characterize the nature and extent of soil contamination, as well as the potential for ground water contamination at or beyond the Findett facility. Findett has installed monitoring wells and begun the ground water monitoring phase of the order. Status (January 1986): EPA sampled wells in June 1985 and developed a workplan for a remedial investigation/feasibility study (RI/FS) to determine the type and extent of contamination at the site and identify alternatives for remedial action. EPA is negotiating with Findett to conduct the RI/FS under a CERCLA Section 106 Consent Order.

According to information provided to EPA as required by CERCLA section 103(c), the plant generated wastes, including the following pesticides; aldrin, dieldrin, 2,4-dichlorophenoxyacetic acid (2,4-D), endrin, heptachlor, methyl parathion, and thiuram. On the site was a 1,250 square- foot lagoon used to treat plant waste and sewage. When the company closed the lagoon in April 1981, it was filled in with compacted clay and covered with another layer of compacted clay. An EPA inspection in May 1983 revealed that the lagoon cover was eroding, and no vegetation was observed on the cover. Heptachlor and endrin were detected in surface soil near the lagoons and in drainage paths leading off-site. In April 1984, EPA detected heptachlor, chlordane, endrin, aldrin, and 4,4-DDD in on-site monitoring wells into the shallow aquifer.. This aquifer, which is not currently used, is connected to a deeper aquifer that supplies private drinking water wells within 3 miles of the site. The wells serve an estimated 1,300 people.

QUAIL RUN MOBILE. MANOR « Gray Summit, Missouri Conditions at listing (September 1983); Quail Run Mobile Manor is a trailer park located 2 miles east of Gray Summit, Franklin County, Missouri. In the early 1970s, the road through the park was sprayed with an unknown quantity of dioxin-contaminated waste oil. In 1974, some of the soil was excavated from the road and deposited in the area between the road and a lagoon and also on two nearby properties which are also part of the site. Early in 1983, EPA identified dioxin in soil samples from numerous locations on the site, one as high as 1,100 parts per billion. As a result, the U.S. Centers for Disease Control (CDC) issued a health advisory warning that the more than 100 residents were at risk of developing adverse health effects from dioxin if .they remained in their homes. Some of-the residents had come to the trailer park from Times Beach, Missouri, which also has a dioxin problem. In May 1983, EPA, the Federal Emergency Management Agency (FEMA), and the State briefed the residents on the findings and explained FEMA's offer of temporary relocation. Of 33 families, 29 applied for relocation. Status (July 1984); A few families are still residing at Quail Run. The site is scheduled to be cleaned up as part of a planned removal using CERCLA emergency funds. The project involves excavating and restoring several on-site areas contaminated with dioxin. The contaminated soil will be stored temporarily on the site. EPA is deferring final rulemaking on this site because it does not meet the criteria currently specified to place a site on the NPL. EPA is considering revising the National Contingency Plan (NCP), the Federal regulation by which CERCLA is implemented, in such a way that Quail Run and similar sites where CDC has issued a health advisory will qualify for the NPL.

Compensation, and Liability Act of 1980 (CERCLAH Superfund WHEELING DISPOSAL SERVICE CO., INC., LANDFILL Amazonia, Missouri Wheeling Disposal Service Co., Inc., operates a landfill on two contiguous areas covering approximately 200 acres. The site is approximately 1 mile southeast of Mazonia in Andrew County, Missouri. The landfill was established in the early 1970s. Between June 1980 and September 1981, the company voluntarily ceased operations pending the issuance of State and Federal regulations on hazardous waste disposal facilities. In September 1981, the facility resumed operations under the authority of a special waste disposal permit issued by the State of Missouri. The Missouri Department of Natural Resources (MDNR) has periodically inspected and monitored ground water at the site since 1975. Based on monthly MDNR hazardous waste logs, wastes containing pesticides (including heptachlor, toxaphene, and lindane), cyanide, arsenic, sulfide, nickel, cadmium, lead, zinc, asbestos, paint sludge, and tanning sludge were disposed of at this landfill. In field investigations conducted by EPA in December 1980, November 1982, and November 1983, trichloroethylene, chloroform, and 1,2-dichloro- ethane were detected in monitoring wells and springs on-site at concentrations significantly above background levels. Drinking water is supplied to 314 residents of Amazonia through wells within 1 to 2 miles of the site and 90 to 100 feet deep in the Missouri River alluvial aguifer. Shallow ground water beneath the site provides partial recharge to the aguifer. Mace Creek, 4,000 feet downslope from the landfill, is threatened by drainage from the site. Local surface waters are used for fishing.

Scmers, Montana Conditions at listing (October 1984); Burlington Northern Railroad has treated ties on a 4.5-acre site in Somers, Flathead County, Montana, since around 1900. The plant's current operations are regulated under the Resource Conservation and Recovery Act (RCRA). An old waste disposal lagoon downgradient of the RCRA-regulated facility has not been used since 1974 and is not regulated by RCRA. The old lagoon was used to dispose of creosote wastes from the wood- treatment process. The wastes were discharged from the pond via a ditch to a marshy area on the shore of Flathead Lake, the largest fresh water lake west of the Mississippi River. The lake is extensively used for camping and fishing, and towns along the lake such as Somers use it for drinking water. On Feb. 28, 1984, the State dug several shallow holes along the lake shore and took samples of creosote-saturated sand below the ditch outfall. Sludge/sediment samples were collected from the bottom of a 0.5-acre swamp pond located along the shore adjacent to the waste ddtch. The material was silty-sandy and stained with oil. Early in March 1984, consultants from Burlington Northern drilled approximately 60 "test borings in the vicinity of the swamp pond, in the waste ditch, and below the seasonal high water beach of Flathead Lake. About 46 percent of the test holes showed visual evidence of creosote contamination. The holes encompassed an area of approximately 3.5 acres, including the pond. Soil samples were collected frcm the test borings. Monitoring wells were installed at 10 sites around the pond. Status (January 1986); In May and June 1985, Burlington Northern removed contaminated sludge, soil, and water from the swamp pond under a CERCLA section 106 EPA Consent Order for an immediate removal. The materials were placed in two existing RCRA lagoons on the plant site which were reconstructed to meet RCRA standards. The conpany is moving the sludges and soils to another of its facilities at Paradise, Montana, where they are being placed in a waste pile that meets RCRA standards. Swamp .pond water was processed through the plant's waste water recycling system. In December 1984, Burlington Northern voluntarily submitted to EPA a remedial investigation/feasibility study (RI/FS) to determine the type and extent of contamination at the site and identify alternatives for remedial action. FPA negotiated with Burlington Northern for further RI/FS studies, and a Consent Agreement was signed on Oct. 9, 1985. RI/FS activities are scheduled to be complete in approximately January 1987. This site remains in proposed status until EPA implements the appropriate elements of its final policy for placing RCRA-related sites on the NPL and then applies the policy to this site.

Lindsay, Nebraska Conditions at listing (October 1984); Lindsay Manufacturing Co. generates acid waste from a qalvanizinq process at its plant in Lindsay, Platte County, Nebraska. The wastes were discharged into a 0.1-acre unlined pond. On Jan. 11, 1983, the company sampled monitoring wells near the pond. Analyses indicate that ground water is contaminated by acid and metals. In October 1983, the ponds were closed. Prior to the closing, the plant received Interim Status, under the Resource Conservation and Recovery Act (RCRA) when the company filed Part A of a permit application. Under a Stipulated Agreement issued by the State, the company has removed the source of contamination and is purging the ground water. Five municipal wells serving the community of Lindsay are within 1 mile of the site. Status (January 1986): Lindsay is pumping ground water and treating it by neutralization and precipitation. The State is monitoring the ground water restoration program. Data from monitoring wells away from the site suggest that the program is controlling the migration of contami- nants from the site. This site remains in proposed status until EPA implements the appropriate elements of its final policy for placing RCRA-related sites on the NPL and then applies the policy to this site.

Site covers approximately 26.3 acres on the Platte River flcodplain on the outskirts of Cozad, Dawscn County, Nebraska. The company began manufacturing activities in Cozad in 1961. In 1981, it employed 600 workers and produced 40,000 shock absorbers each day. The company is owned by Tenneco and is still in operation. Manufacturing processes include metal finishing, welding, painting, electroplating, and reclaiming of waste oil. Sludges generated from treating plant wastes contain chromium, cadmium, and zinc. This sludge is stored in on-site surface impoundments. Underground tanks for storing organic solvents are also on the site. Results fron an 1982 EPA Water Supply Survey revealed that two of Cozad's seven drinking water wells, located in the vicinity of the Monroe site, were contaminated with trichlorcethylene and other synthetic organic compounds. The well system serves 4,400 people. Subsequent sampling showed that significant levels of trichloroethylene and acetone exist in on-site wells. The Platte River and the Dawson County canal (which is about 2,000 feet downstream of the site) are used for irrigation. On Jan. 18, 1983, EPA Headquarters granted a temporary exclusion delisting Monroe Auto sludge under the Resource Conservation and Recover/ Act (RCRA). The surface impoundments, therefore, are not currently subject to-Interim Status requirements of RCRA. EPA has asked the company to supply new information on the sludge to meet the requirements of the RCRA amendments passed in November 1984. Additional data are needed to establish which part of the facility is responsible for ground water contamination.

From 1965 to 1973, the owner/operator accepted raw sewage and septic wastes from various industries. The sit£ is in a marshy area, and the wastes were dumped as fill. Wastes were deposited below the water table. The site was unlined and had no leachate controls. In 1970 Horstmann registered as a public utility. Subsequently, citizens objected about Horstmann's operations to the New Jersey Department of Environmental Protection (NJDEP) and the New Jersey Board of Public Utilities (NJBPU). In 1973, Horstmann petitioned NJBPU to stop operations, which NJBPU agreed to. As a result of this action, NJDEP in 1974 ordered the site to close so that closure requirements could be enforced. In 1984, EPA tests found lead, nickel, mercury, volatile organic . chemicals, and PCBs in on-site soil. The soil is highly permeable, which facilitates movement of contaminants into ground water. About 75,000 people draw drinking water from public and private wells within 3 miles of the site. A .well of the South East County Utilities Authority is less than 2,000 feet away. Surface.water is threatened because the site is in a swampy area and is surrounded by wetlands.

In December 1983, the State closed the well, which is one of nine wells serving about 24,000 people. Other municipal wells are being used, but they draw from the same aquifer. The State is investigating to determine if ground water migrating from a nearby thorium-processing facility is contaminating the Lodi Municipal Well. Status (January 1986): Additional tests of the well water are planned to determine if the radionuclides present are associated with a naturally-occurring formation in the area. The analyses will also include nonradiological constituents, which are used to help identify the source of contaminants. EPA is deferring final rulemaking on this site because it needs more time to analyze the conments received during the public comment period. Thus, the' Lodi Municipal Well will remain in proposed status until a later rulemaking.

Fran 1962 to 1976, rinse water from the cleaning of tanks used for transporting a variety of materials (including resins, organic solvents, and acids) was disposed of in an unlined sand and gravel pit behind the terminal building. At the end of disposal operations, Matlack punped the lagoon and left the sludge in place. The pit was subsequently filled with demolition rubble and clean fill. The New Jersey Department of Environmental Protection (NJDEP), Gloucester County Health Department, and Matlack have sampled ground 'water and soil both on- and off-site. The results indicate that on-site soils are contaminated with volatile organic chemicals, including trichloroethane, tetrachloroethane, and 1,2-dichloroethene. A private residential well about 0.25 miles northwest of the site is similarly contaminated. The residents are now using bottled water. On January 18, 1984,^JDEP notified Matlack that it should investigate hydrogeological conditions at the site. In response, Matlack hired a consultant to install and sample additional monitoring wells. About 300 people within 3 miles of the site are served by ground water.

Since the early 1940s, the U.S. Navy has handled, stored, renovated, and transshipped munitions at the station. These operations involve preserving and maintaining ammunition, missile components, and explosives; rendering safe unserviceable and/or dangerous ammunition and explosives; and providing support to the Fleet Mine Facility. The station also conducts or has conducted nonordnance activities, radiological operations, materials storage, and waste disposal operations. Site A covers 29 waste areas identified by the Navy. Wastes generated in Site A include ordnance materials, grit and paint, paint scrapings, solvent/paint sludges, ammonium picrate, lead bullets from small arms ranges, zinc, lead, titanium, and small amounts of other constituents. The Navy detected contaminants in a limited number of sediment and surface water samples, but further background samples are necessary. The waste areas of Site A overlie the Cohansey Sand, Kirkwood Formation, Vincentown Formation, Red Bank Sand, Navesink Formation/ and the Wenonah Formation aquifers. All are hydraulically connected, so that water can move among them. An estimated 1,900 people within 3 miles of Site A are served by these aquifers. Local surface water is used for recreation and irrigation purposes. An estimated 270 people are served by surface water within 3 miles downstream of Site A. The station is participating in the Installation Restoration Program, the specially funded program established in 1978 under which the Depart- ment of Defense has been identifying and evaluating its past hazardous waste sites and controlling the migration of hazardous contaminants from these sites. The Navy has completed Phase I (records search). Phase II (preliminary survey) is underway. Status (July 1985): EPA and the Navy have agreed upon a scope of work which calls for investigation of 13 of the 29 areas.

Bohemia, New York Conditions at listing (June 1986); BioClinical Laboratories, Inc., formulated and mixed organic and inorganic chemicals for repackaging and distribution in Bohemia, Suffolk County, New York, from 1978 to 1981. The company occupied one 3,000-square-foot unit of a 10 unit one-story brick building. Drums used for mixing chemicals were washed for reuse; the rinse water was routinely dumped down sink drains or directly onto the ground. Leaking drums containing hazardous wastes were stored outdoors for long periods of time, according to Suffolk County. After receiving complaints, the County Department of Health investigated and sampled surface water, storm drains, sanitary drains, and leaching pools on the site. The Health Department detected high levels of organic solvents and heavy metals, chloroform at particularly high levels. In November 1981, five months after the highest level of chloroform was confirmed, the Health Department ordered the company to pump out a septic tank and pool. In August 1981, the county issued a Consent Order to BioClinical Laboratories, citing several violations, including improperly storing hazardous materials, discharging materials in excess of ground water standards, and not possessing a permit under the State Pollutant Discharge Elimination System. The company has not installed monitoring wells, as reguested by the Health Department. BioClinical Laboratories abandoned the site following a fire in July 1981. The site is currently occupied by the American Flagpole Division of Kearney National Co. One well in the Suffolk County Water Authority's Locust Avenue Well Field is within 0.5 miles of the site. The well taps the contaminated aguifer, which is the sole source of drinking water for about 11,000 people within 3 miles of the site.

The lower or eastern-most landfill, which operated fron 1964 to 1969, consists of three linear trenches. Assuming an average depth of 30 feet for each trench, the lower landfill contains approximately 3.7 million cubic feet of waste material. Preliminary indications are that the landfill contains municipal solid waste, according to a consultant to the Broome County Industrial Development Agency (BIDA), which is considering purchasing the property to create an industrial park. Some industrial and chemical wastes also may have been deposited. The upper landfill operated from 1969 until it closed in 1975 under a closure order issued by the State. Most of the waste deposited in this landfill was placed in six unlined cells; subseouently, additional waste material was piled over the cells. The majority of the waste is municipal solid waste, although sampling indicates that some industrial and chemical waste may have been deposited. Assuming an average depth of 25 feet, the total filled volume of this landfill is estimated at 6.9 million cubic feet. The State has observed leachate from the dumps draining towards Carlin Creek, a tributary to the Susguehanna River, which is used for recreation. Ground water on the site is grossly contaminated with arsenic, chromium, mercury, and various organic chemicals, including benzene, according to tests conducted by BIDA's consultant. Private wells near the site contain high levels of arsenic and traces.of organic chemicals, according to the consultant and the New York State Department of Health. The lower dump is in highly permeable soils and is about 800 feet upgradient frcm residential areas using private wells. About 2,000 people depend on wells within 3 miles of the site for their drinking water.

The landfill is roughly L-shaped and occupies approximately 13 acres on a 25-acre privately-owned property fronting on Penaluna Road. The surrounding area is generally hilly, with residential clusters and wooded areas. Both wetlands and rock outcrops exist adjacent to landfilled areas. In about 1957, the town started to accept municipal wastes at the site under a permit from the Orange County Department of Health. Industrial chemical wastes also may have been disposed of at the site over an undetermined period of time. In 1977, the owner leased the site to Grace Disposal and Leasing, Ltd., of Harriman, New York. In 1979, the State identified volatile organic compounds in leachate at the site. The State subseguently issued a restraining order and closed the landfill. Later, the State found relatively low levels of organic and metal compounds in soil, ground water, surface water, and sediment on the site. Drainage from the landfill enters a stream south of the site which flows into Greenwood Lake, a major recreational resource approximately 0.5 miles from the site. The landfill is unlined and overlies moderately permeable soil and rock. Ground water is found at shallow depths (between 1 and 2 feet).

The site consists of five dumps within 2 miles of each other. All but one are privately owned. The Fairway Six dump covers approximately 1.5 acres and was discovered in August 1984 during construction of a new golf course. In October 1984, the North Carolina Solid and Hazardous Waste Management Branch (SHWMB) found several bags labeled toxaphene and noted a strong chemical odor. The soil contained DDT, ODD, toxaphene, and lindane (BHC), according to SHWMB analyses. The Twin dumps cover about 1 acre; one is privately owned and one is owned by Aberdeen and used for recreation. They are within 350 feet of each other. The dumps were reported to SHWMB in August 1984 by State highway personnel who had smelled chemical odors in the area. SHWMB detected various pesticides in Twin dumps soil. Several operations have manufactured pesticides in a building 500 feet from the dumps: Taylor Chemical Co. (1936-64); E-Z Flo, owned by Union Carbide Corp. (1964-72); and Farm Chemicals, Inc. (1972 to the present). The Mclver pesticide dump covers approximately 1 acre. It was discovered in November 1984 when SHWMB, acting on information provided by a citizen, found 200- 300 55-gallon pesticide drums in Lucks Landfill, a rubble landfill occupying a leased portion of the Mclver property. The State determined that the drums con- tained small amounts of parathion and had been shipped by Farm Chemicals, Inc. Soil at the landfill contains many of the same pesticides found at the other dumps. Further investigation found another area where pesticide bags and residues had been dumped. In February 1985, the State, Farm Chemicals, Inc., and Lucks Construction Co. signed an Administrative Order on Consent requiring the companies to remove the drums from the Mclver dump. In March 1985, 687 drums were removed, steam cleaned, triple rinsed, crushed, and sent to the Moore County landfill. Rinsate was applied to farm land as per label directions for the pesticide. In June 1985, using CERCLA emergency funds, EPA removed pesticide-contaminated soil and wastes from the Fairway Six, Twin, and Mclver dumps. The Route 211 dump covers approximately 0.75 acres. The owner re- ported it in July 1985 after EPA emergency actions. SHWMB investigated, finding a pile containing cardboard containers, pesticide bags (one marked Taylor Chemical), and various powders and tarry residues. SHWMB detected various pesticides in soil. The 0.5-acre Farm Chemicals, Inc., dump is approximately 500 feet from the Twin dumps. The company has manufactured pesticides since 1972. Previously, E-Z Flo (1964-72) and Taylor Chemical (1936-64) manufactured pesticides there. After discovery of the four other pesticide dumps, EPA investigated Farm Chemicals in May 1986. Various pesticides and PCB-1242 were found. Soils at all five areas are permeable, facilitating movement of contaminants into ground water. Nearby Page's Lake is also potentially threatened.

TRW purchased the initial property in 1954 and expanded twice by addinq adjacent properties. Farmland lies to the north and east of the site. The TRW property extends south to Sandy Creek, which is used for recreation. The plant conducts metal-castinq operations. Until 1976, PCBs were used as working fluids in diffusion pumps. Spent PCBs were stored in drums on the back pad of the plant and apparently leaked into the drainage ditch adjacent to the pad. Waste wash water and spent casting wax, which may have come into contact with the PCBs, were discarded into a ditch that flowed to the south to a pond. Volatile organic chemicals (trichloroethylene before 1972 and 1,1,1-trichloroethane after 1972) were used as degreasers, and spent degreasers were discharged to the ditch. Ground water on the site is contaminated with PCRs, trichloro- ethylene, 1,1,1-trichloroethane, 1,1-dichloroethane, and 1,1-dichloro- ethylene, according to analyses conducted by a consultant to TRW. Minerva city wells are located approximately 1 mile southwest and downgradient of the TRW building, west of Sandy Creek, and south of Route 30. The wells draw water at. 30 to 120 feet from a sand and gravel aguifer, the same aguifer that underlies TRW property. The wells serve 4,560 people.

Wbrman, Pennsylvania CryoChem, Inc./ has operated a metals-fabrication facility on a 19-acre site in Woman, Berks County, Pennsylvania, from 1962 to the present. The facility is composed of several production and storage buildings and an office complex situated at the lower portion of the property. The company uses solvents to clean finished metal parts. Any excess solvent is collected in shop drains. Prior to 1982, the company used about one 55-gallon drum of 1,1,1-trichloroethane per year for 3 or 4 years and allowed the shop drain system to discharge into nearby surface waters that lead to Manatawny Creek. In August 1981, the Pennsylvania Department of Environmental Resources (PA DER), acting on complaints of area residents, began sampling residential wells. Analysis of nine wells downgradient of the site detected chlorinated solvents, including 1,1,1-trichlorethane. In June 1982, PA DER detected up to 270 parts per billion (ppb) of 1,1,1-trichloro- ethane on-site in an unnamed tributary to Ironstone Creek, which is used for fishing. As a result of this discharge, PA DER notified the company that it was in violation of the Pennsylvania Clean Streams Law. PA DER also recommended that the company discontinue the use of 1,1,1- trichloroethane, clean out the drain system, and properly dispose of all contaminated materials. The company complied with the recommendations. Since the original sampling, PA DER has extensively sampled resi- dential wells located near and mostly downgradient of the site. Concen- trations of 1,1,1-trichloroethane generally ranged from 0 to ]80 ppb, and one measured 600 ppb. PA DER notified the affected residents of the contamination.

Hellertown/ Pennsylvania HelXertown Manufacturing Co., a subsidiary of Champion Spark Plug Co., of Toledo, Ohio, formerly manufactured spark plugs at 1770 Main Street in the borough of Hellertown, Northampton County, Pennsylvania. Operations commenced at the facility in 1930 and continued until it closed in October 1982. Between 1930 and 1976, Hellertown used five on-site lagoons for the disposal of its wastes. According to a preliminary assessment made by the Pennsylvania Department of Environmental Resources (PA DER), the wastes disposed of on-site included zinc plating waste, chrome dip waste, cleaners, and cutting oils. The lagoons were unlined, thereby permitting wastes to seep into the local soils and rock strata. The lagoons covered approximately 50,000 square feet and could hold an estimated 18,400 cubic yards. In 1970, the company reported that it discharged 300,000 drums of wastes to the lagoons. In 1976, all five lagoons were filled with excavated material from construction of the City of Bethlehem Waste Water Treatment Plant. From 1976 until 1982, Hellertown wastes were discharged into the local sanitary sewer system. Ground water underlying the site is contaminated with 1,2- dichloroethylene, trichloroethylene, vinyl chloride, tetrachloroethylene, and 1,1,1-trichloroethane, according to tests conducted by PA DER in early 1985. This aquifer within 3 miles of the site supplies water to the Hellertown Water Co., the Bethlehem Steel Corp. plant, and private residences, affecting an estimated 15,000 people.

The privately-owned landfill started operating in the late 1960s. Initially, demolition wastes were disposed in an abandoned quarry on the site. Later, the landfill began accepting municipal and industrial wastes. In 1980, a new phase began when the first of five trenches was excavated. Disposal in these trenches was under a solid waste permit from the Pennsylvania Department of Environmental Resources (PA DER). PA DER closed the landfill in December 1984. General Electric Co. notified EPA, as required by CERCLA section 103(c), that its Allentown, Pennsylvania, plant had sent electroplating wastes containing heavy metals and organic wastes, including spent solvents, to the landfill. According to PA DER, other industrial clients of the landfill include Tyler Pipe Co., Tarkett Corp., Western Electric, and Caloric Corp. Ntonitoring wells on the site are contaminated with a variety of organic and inorganic chemicals, including tetrachloroethene, toluene, 1,1-dichloroethane, and barium, according to EPA tests. A private well 1,200 feet southwest of the landfill boundary is similarly contaminated, according 'to EPA and PA DER. The landfill is in a limestone region that is very susceptible to ground water contamination and migration of contaminants. An estimated 17,300 people draw drinking water from public and private wells within 3 miles of the site. In January 1985/ South Whitehall Township extended its water line to two residences near the landfill, because a well sampled by EPA contained organic and inorganic contaminants which could also be attributed to the landfill. According to an EPA inspection in June 1984, a ditch encircling the site diverts run-off and leachate into an on-site pond. The diversion ditch and pond are not properly engineered, and the landfill is not adequately covered. Hence, surface water in the area is threatened.

The site consists of an electric train repair facility and a commuter rail station owned by Mtrak and operated by the Southeastern Pennsylvania Transportation Authority (SEPTA). Commuter trains are serviced, repaired, and stored at this facility. Routine maintenance and repair of railroad cars involve PCB-containing electrical equipment. The site is surrounded on three sides by residential communities and on the fourth side by commercial facilities. Until recently, the site was unsecured and easily accessible. Residents and commuters regularly used it as a shortcut to reach both the train station and the cormercial properties. In the late 1970s, both EPA and the Pennsylvania Department of Environmental Resources (PA DER) inspected the Paoli Rail Yards. This inspection, coupled with subsequent State investigations, led PA DER to issue an order in 1979 requiring Mtrak and SEPTA to determine the extent of contamination and correct any problem areas. Amtrak and SEPTA took some actions primarily involving collection of samples, seme cleanup efforts, and further study of the site. In November 1985, analyses of samples taken in July 1984 by a consultant to Amtrak and SEPTA were made available to EPA. The results indicate that a severe PCB problem exists at this site, with contamination ranging as high as 3 percent in on-site soils and to depths of up to 3 feet. In December 1985, a team consisting of staff from EPA, the Federal Agency for Toxic Substances and Disease Registry, and the State Health Department made a preliminary assessment of the rail yards. The purpose of this assessment was to verify the existing sample results and identify those areas that were of most concern. The sampling effort was centered around the immediate threat posed by the presence of high levels of PCBs both on site and in the residential community. On February 25, 1986, EPA filed a complaint in Federal court under the Toxic Substances Control Act, CERCIA, and the Resource Conservation and Recovery Act. The complaint seeks an order requiring the responsible parties to limit access to the site, control migration of PCBs, conduct sampling and analysis, and take measures to clean up the site and protect worker safety. A Consent Dacree was also lodged on the same date. As a first step, SEPTA installed a security fence around the site.

The site is in northwestern South Carolina, in Pickens, Pickens County. Sanqamo has manufactured electrical capacitors on a 224-acre area in Pickens since 1955. PCBs were used in production of the capacitors between 1955 and 1976. As required by CERCLA section 103(c), Sanqamo notified EPA that it had disposed of approximately 38,700 cubic yards of PCB-contaminated waste on its plant site and an undetermined amount of waste in seven satellite dumps., all in the Twelve-Mile Creek Basin. Solid, sludqe, and liquid wastes were stored or disposed of in piles, landfills, and impoundments. EPA is continuinq to search for any additional sources of contamination that may exist. EPA and the South Carolina Department of Health and Environmental Control (DHEC) detected .PCBs in run-off leavinq the Sanqamo-Weston Pickens Plant and throuqhout the Twelve-Mile Creek Basin, includinq Lake Hartwell. Specific streams in which PCBs have been detected include: unnamed tributaries located downqradient from the Sanqamo-Weston Pickens Plant and flowinq into Town Creek, Twelve-Mile Creek, Golden Creek, Middle Fork Twelve-Mile Creek, and North Fork Twelve-Mile Creek. Lake Hartwell and Twelve-Mile Creek are used for recreation ' and drinkinq water. In December 1984, residents of Catteechee, South Carolina, initiated law- suits aqainst Sanqamo and two other companies over alleqed health effects resultinq from exposure to PCBs. Sanqamo-Weston has removed over 17,000 cubic yards of PCB-contaminated waste from some past disposal areas located on and off the plant property. These wastes are contained in an EPA-approved landfill. PCBs have been detected by DHEC and EPA in the drinkinq-water distribution system of the Easley-Central Water Plant, which serves -14,500 people. The plant intake is in Twelve-Mile Creek. Clemson University has an intake in the Twelve- Mile Creek arm of Lake Hartwell. It serves 15,800 students and employees. PCB contamination in Lake Hartwell and its tributaries was first discovered in 1975. It was traced to effluent from the Sanqamo-Weston Pickens Plant and from other sources in the watershed. Since 1977, EPA and DHEC have monitored PCB levels in fish taken from Lake Hartwell. Over the years, levels have been declininq, althouqh the rate of decline appears to be slowinq. From 1983 until early 1986, the Aqency for Toxic Substances and Disease Reqistry reviewed data reqardinq possible exposures to PCBs in Pickens County. The aqency said PCBs appear to present no imminent or substantial public health threat._ In Auqust 1986, EPA neqotiated a Consent Aqreement with Sanqamo-Weston for samplinq to determine the extent of contamination at the Brazeale dump, one of the seven satellite dumps. The 0.5-acre dump was used for landfillinq 24,000 cubic feet of PCB waste. The Brazeale property is on Wolf Creek Road about 1 mile southwest of Pickens. In November 1985, after findinq PCB levels as hiqh as 27,000 ppm in soil samples, EPA removed a mobile home from the property.

In 1969, the company, now known as Mallory Capacitor ;Co. , began to manufacture capacitors using PCBs as a dielectric fluid. In 1978, Mallory switched to dioctyl phthalate as a dielectric fluid. Dart Industries, Inc., acquired Mallory Capacitor Co. in early 1979 and sold it later in the year to Ehihart Industries, Inc. As part of the sales agreement with Bnhart, certain PCB wastes, a buried tank, and contaminated soil were removed from the site and sent to an approved PCB disposal facility. - PCBs entered the environment through spills, leaks, and intentional sdischarges, according to investigations conducted by EPA. On July 31, ':1984, the plant voluntarily closed because of the discovery of PCB contamination throughout the site. In 1985, tests conducted by EPA, Mallory, and its contractors detected PCBs in on-site sand and off-site wells downgradient of the site. An estimated 900 people obtain drinking water from wells and springs within 3 miles of the site. Sediments downstream from the site also contain PCBs, according to Mallory. Surface water within 3 miles downstream of the site is used for fishing and swimming.

General Dynamics operates the plant, which manufactures aircraft for the Air Force. In November 1982, the Air Force and General Dynamics notified EPA via the National Response Team that hazardous substances were found in a storm water outfall that drains into a creek on the west side of the plant. Under Air Force supervision, General Dynamics con- structed a french drain and a collection basin at the outfall. Since that time, leachate from the drain and outfall has been collected, stored, and disposed of in an EPA-approved disposal facility. In 1983, the Air Force removed 21,300 cubic yards of contaminated soil-from closed waste pits and disposed of the soil at an approved disposal facility. The Air Force has drilled numerous test holes and 97 monitoring wells in and around 20 areas, which cover a total of about 8 acres. Many of the areas have contained hazardous substances. Analyses of the wells indicate that ground water in the upper zone under the site is contaminated with several organic chemicals and heavy metals. Several deeper wells were drilled at the site into the Paluxy aquifer, which is the source of drinking water for nearby residents, including the municipality of White Settlement (population 13,420). Two wells have been found to be contaminated by 1,2-transdichlorethylene and trichloroethylene. The plant is participating in the Installation Restoration Program, the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past hazardous waste sites and controlling the migration of hazardous contaminants from these sites. At the reguest of the Air Force, EPA has further investigated off-site areas, including several White Settlement wells, sediment in the creek and Lake Worth, and selected residential wells near the site. EPA drilled four monitoring wells near the plant area. The White Settlement municipal wells and the four EPA wells are monitored on a quarterly basis by EPA. In November 1980, the facility received Interim Status under the Resource Conservation and Recovery Act (RCRA) when General Dynamics and the Air Force filed Part A of a permit application to treat and dispose of hazardous wastes. Status (April 1987); Phase II (preliminary survey) of the Installation Restoration Program is underway. This site is being reproposed to be consistent with EPA's recently proposed policy for placing on the NPL sites located on Federally-owned facilities that are subject to the corrective action authorities of Subtitle C of RCRA.

Compensation, and Uabillty Ac. of 1980 SHERIDAN DISPOSAL SERVICES Hempstead, Texas The Sheridan Disposal Services Site is approximately 9 miles north- northwest of Hempstead in a predominately agricultural area in Waller County, Texas. It consists of a 1,4-22 acre surface impoundment and a 40-acre. evaporation system; at one time, an incinerator also was in operation. The company collected a wide range of petrochemical and general industrial wastes from Gulf Coast industries. The impoundment began operation in the late 1950s. The State ordered it to close in 1976, then in 1984 ordered the entire site to close. In response, Sheridan Disposal Services constructed the 40-acre evaporation system for treatment of accumulated rain water and covered approxi- mately 7 acres of the impoundment with construction debris and soil. Of the two shallow water-bearing zones at the site, the upper zone is contaminated with about 200 parts per billion, total, of chlorodibromanethane , 1, 1,1-trichloroethane, and isophorone, according to limited data collected by EPA and parties potentially responsible for wastes associated with the site. The extent of contamination of both zones is being studied in an ongoing remedial investigation of ground water. The deeper zone provides drinking water for approximately 500 people within 3 miles of the site. The site is located in alluvial deposits about 250 feet from the Brazos River, within the 100-year floodplain. The Brazos River is not now impacted by the site, according to EPA analyses of upgradient and downgradient samples of river water. A water overflow from the site in 1978 caused a fish kill in Clark Lake, a private lake adjacent to the site. Recent air testing by EPA found that no toxic compounds were present above background levels. In April 1984, approximately 60 potentially responsible parties set up the Sheridan Site Cotmiittee. It began negotiating with the State and EPA, hired an engineering contractor who is investigating ground water at the site and has also taken the following remedial actions: transferred approximately 1.5 million gallons of water from the impoundment to the evaporation system; repaired, strengthened, and raised the dikes around the impoundment and the evaporation system to above the 100-year floodplain; and transferred approxi- mately 6,000 gallons of oil floating on top of the impoundment to on-site tanks . On February 5, 1987, the Sheridan Site Committee entered into an Administrative Order on consent with EPA to conduct a remedial investigation/ feasibility study to control the source and migration of contaminated ground water from the site.

Midvale (population 10,000) is part of the Salt Lake City Metropolitan area (population 936,000). Between 1902 and 1971, United States Smelting, Refining and Mining Co. smelted ores on the site to produce copper, gold, lead, and silver. The site consists of piles of slag estimated at 2 million tons that remain from the smelting operations. The smelter no longer exists. In 1971, Valley Materials, Inc., acquired the site and processes the slag into materials for railroad beds and asphalt highways. Testing by the Utah Department of Health indicated that the slag contains high concentrations of arsenic and heavy metals. The slag is found on the surface and down to a depth of 20 feet. Hence there is a potential for ground water contamination. Several municipal wells serving an estimated 38,000 people are within 3 miles of the site. The Jordan River, which forms the western boundary of the site, is not contaminated to date, according to tests conducted by EPA in May 1985. However,, slag piles are as close as 50 feet to the river, causing concern that the river can become contaminated.

Subsequently, the site was subdivided into parcels of 6 and 9 acres, which are now owned by two separate entities. Lot 6 has not been used since before 1980. The Utah Department of Health estimates that approximately 2,300 cubic yards of wastes have been disposed in a concrete pond and in drums on Lot 6. During an inspection in June 1985, the State found 48 drums holding ignitable and reactive liquids and 13 pressurized gas cylinders in poor condition; several of the drums were leaking. Residential and commercial industrial areas are within a few hundred yards of the drum storage area. Approximately 85,000 people live within 3 miles of the site. Additional wastes from the operation were discharged into the 700 West Stream, a ditch that drains into the Jordan River. Tests conducted by the State in June 1985 detected several chemicals, including pesticides and methyl isobutyl ketone, in ground water. 700 West Stream also has elevated levels of some of these compounds. About 60,000 people obtain drinking water frcm private wells within 3 miles of the site. The nearest well is within 2,000 feet. No alternative source of water is available in the area. The Jordan River/Surplus Canal is used primarily for industrial, irrigation (3 square miles), and recreational purposes. In January 1986, the State requested the owner of Lot 6 and a number of other parties potentially responsible for wastes associated with the site to remove drums and other materials from Lot 6. When they refused, the State filed an action in Federal Court seeking the potentially responsible parties (PRPs) to remove the drums and compensate the State for its costs. in February 1986, the State and EPA negotiated a Consent Order under CERCLA section 106 for the drums. In April 1986, during a CERCLA emergency removal action, EPA detected dioxin in drums, standing water, and soil on the site. In the removal action, EPA (1) excavated contaminated soil, (2) transported non-dioxin drums and soil and the cylinders to a hazardous waste landfill permitted under the Resource Conservation and Recovery Act, and (3) placed dioxin- contaminated materials in a temporary storage unit adjacent to Lot 6. EPA has reached a partial agreement with several PRPs to pay for a portion of the emergency action.

Subsequently, the facility accepted 1,254 drums of used organic solvents and flammable liquids/solids. These wastes were placed, in trenches separated from the previously closed portion of the site. The facility stopped accepting hazardous waste after December 1981. In May 1983, Buckingham County closed the new portion of the site in accordance with plans approved by the Virginia State Health Department. Sampling conducted by EPA in September 1983 indicates that on-site ground water and off-site residential well water are contaminated by chromium and beryllium. In early 1985, one residential well was contaminated. About 1,100 people depend on wells within 3 miles of the site as a source of drinking water. Status (January 1986); In late 1985, EPA determined that an immediate removal was not warranted at that time.

(VIRGINIA WDOD PRESERVING DIVISION) Richmond, Virginia Rentokil, Inc. (Virginia Wood Preserving Division) has operated.a wood-treatment facility on a 4-acre site in Richmond, Henrico County, Virginia, since 1965. Until about 1981, the company used creosote and pentachlorophenol as preservatives. In 1982, use of pentachlorophenol was discontinued, and chromated copper arsenate came into use. Creosote continued in use. EPA has detected high concentrations of chrcmated copper arsenate in an unlined surface impoundment on the site. Rentokil has detected the seme contaminant in run-off, soils, and a monitoring well on the site. An estimated 350 people draw drinking water from private wells that tap the contaninated aquifer within 3 miles of the site. The nearest private well, which is within 1,300 feet of the site, is not contaminated to date. Run-off from the site enters North Run, which is used for swimming within 1.5 miles of the site.

Chuckatuck, Virginia Saunders Supply Co. has treated wood on a site in Chuckatuck, Suffolk County, Virginia, since 1964. From 1964 to 1984, the facility used a pentachlorophenol/No.2 Fuel Oil mixture as a wood preservative. Chronated copper arsenate was also used starting in 1974 and is still in use. The spent pentachlorophenol/oil mixture was disposed by burning in an unlined pit, which resulted in the generation of dioxin compounds. Tests conducted by EPA in November 1984 detected elevated levels of chromium in Godwin's Mill Pond Reservoir, a source of drinking water for over 30,000 people in Suffolk, Virginia. A fresh-water wetland is within 1,000 feet downstream of the point where chromium was found. The tests also found pentachlorophenol, lead, chromium, and arsenic in the Columbia aguifer, which supplies private wells serving over 1,990 people within 3 miles of the site. The nearest well is approximately 1,900 feet from the site. In 1983, the company excavated some contaminated soil and transported ib to an EPA-approved landfill. A recovery well was drilled, and contaminated ground water is pumped out of the well and recycled back into a treatment system.

The main station, which is located on a peninsula 15 miles west of Seattle, covers slightly over 200 acres and employs approximately 3*500 people. NUWES (Keyport) has been involved in a wide variety of activities, including maintenance of torpedoes; storage of fuel and ordnance; and production functions such as welding, plating, painting, carpentry, and sheet metal work. Waste contaminants generated include cadmium, chromium, copper, cyanide, lead, nickel, tin, zinc, carbon tetrachloride, methyl ethyl ketone, and trichloroethylene. Four waste disposal areas are included in this NPL site. The areas are part of the same operation, have the same sources of contamination, and have the same contaminants. They also threaten the sane ground water and surface water. The four areas are: Keyport Landfill, situated in a marsh and having no liner or leachate containment system; the Van Meter Road Spills, an area about 100 x 200 feet located near an intermittent creek that flows into a lagoon used for fishing and swimming; Sludge Disposal Area, which covers about 100 feet x 200 feet and is located less than 200 feet from Liberty Bay; and Liberty Bay Outfalls/ Shoreline, where very substantial quantities of wastes were discharged directly into the water. The waste from at least one of these areas, Keyport Landfill, is in direct contact with ground water. Thousands of gallons of wastes were dumped onto the ground at the Van Meter Road Spill area. Up to 500 gallons of sludge were disposed of at the Sludge Disposal Area. Sediment from the Liberty Bay Outfalls/ Shoreline area and from the landfill contain lead, cadmium, chromium, and zinc, according to analyses conducted by a consultant to the Navy. Liberty Bay is used for commercial shell fishing and recreation. There are 135 private wells and 22 public-suppply wells drawing from the surficial aquifer within 3 miles of the site. The wells serve a total of 230 households. NUWES (Keyport) is participating in the Installation Restoration Program, the specially funded program established in 1978 under which the Department of Defense has been identifying and evaluating its past . hazardous waste sites and controlling the migration of hazardous contami- nants from these sites.

The property previously was owned by Inland Asphalt Co., but it is now under new ownership. In 1976, the unlined gravel pit began accepting baghouse emission dusts from Spokane Steel Foundry Co. The company manufactures iron and steel parts at a foundry across the road from the Old Inland Pit. The pit is still operating, and during a recent EPA inspection there was evidence that baghouse emission dusts apparently continue to be dumped. Wastes in the pit contain toxic metals (arsenic, cadmium, chromium, and lead) and organic chemicals (acetone, methylene chloride, toluene, and trichloroethylene), according to tests conducted by EPA... The site overlies the Spokane Valley-Rathdrum Prairie Aquifer, which is the sole source of drinking water for more than 30,000 people within 3 miles of the site. The soil is permeable so that contaminants can move into ground water.

The City of Tomah owned and operated the site from 1960 to 1979. It was licensed by the State to accept municipal refuse. One local facility, Union Camp Corp., notified EPA, as required by Section 103(c) of CERCLA, that it had sent to the landfill 1,514 drums of wastes containing barium, chromium,, lead, spent halogenated and nonhalogenated solvents, ethyl acetate, and 1,1,1- trichloroethane. In June 1984, EPA inspected the site and sampled ground water and sediments in Deer Creek, which runs through the site. On-site ground water was contaminated with heavy metals, including cadmium, chromium, lead, and zinc, and organic chemicals, including benzene, toluene, vinyl chloride, and xylenes. The sediments were contaminated with arsenic, chromium, copper, lead, zinc, toluene, tetrachloroethene, and 2-butanone. The City of Tomah's municipal well field, which serves 7,330 people, is 2 miles from the site. An additional 1,700 people get drinking water from private wells within 3 miles of the site. Deer Creek, which is nearby, is a trout stream. A fresh-water wetland is within 1,000 feet of . the site.
