Thank You! ------- ------- COMPASS INDUSTRIES (AVERY DRIVE) OKLAHOMA EPA ID# OKD980620983 REGION 6 SIGNAL DISTRICT 01 Tulsa County handler Park Iher Names: Cbandtor Landfill Site Description Location: »The site is a former landfill located in a previously operated quarry in the Chandler Park area west of Tulsa, Tulsa County, Oklahoma. Population: The Tulsa metropolitan area has a population of 376,000 Setting: « Nearest residence is 1/4-mile from the site. Nearest drinking water well is approx. 1/2-mile from the site, is not currently in use, and is up-gradient. Approximately 30 acres in area, depth of refuse and hazardous waste is approximately 20 feet. Geology: The site is located on a bluff adjacent to the Arkansas River. Waste is located in a stone quarry in the Hogshooter Limestone formation, which varies between 20 and 30 feet thick. Beneath the site is the Coffeyville formation, consisting of shales interspersed with minor sandstones and siltstones. Wastes and Volumes Principal pollutants at the Compass Industries Superfund site include waste jet fuel and oily sludges, miscellaneous solvents, acids, caustics, bleaches and benzene. PCBs and pesticides have also been detected. The absolute volumes of pollutants are generally unknown, but are estimated to be approximately: 22,000 gallons of waste jet fuel, 4,000 gallons of solvents and 3,300 gallons of the caustics, bleaches and benzene. Site Assessment and Ranking NPL LISTING HtSTORY Site HRS Score: 60.57 Proposed Date: 9/08/83 Final Date: 9/21/84 NPL Update: No. 1 December 4, 1995 ------- One potentially responsible party (PRP), Texaco, stated that a ground water score was assigned but that no ground water testing was done, that the air data was insufficient to document an air release, and that tests failing to detect hazardous substances were not taken into account in computing the HRS score. EPA responded that the HRS score was based on route characteristics, that an air release was properly assigned, and that negative results do not counter positive results. Site Map and Diagram COMPASS INDUSTRIES SUPERFUND SITE The Remediation Process Stte History: The site, originally a limestone quarry (1930s), was a permitted landfill which accepted an unlcnown quantity of hazardous wastes from the surrounding industries. The landfill operated from 1964 to the late 1970s. One PRP, Ashland Chemical Co., responded during the National Priorities List (NPL) Proposal comment period that they would not participate in the remediation. Site caught fire underground and burned for more than a year (1982). May - June 1988, EPA installed a fence and posted warning signs around its perimeter. The Remedial Design (RD) was completed in 4/89 under OSDH and U.S. Army Corps of Engineers project oversight. December 4,1995 COMPASS INDUSTRIES (AVERY DRIVE) ------- Winter turfing had to be planted during fall 1990, thus extending the Remedial Action schedule. Final turfing was planted during summer 1991, which facilitated better growth. Operation and Maintenance (O&M) began in September 1991 with collection of seepages and background samples. Subsequent fiscal quarters of sampling (through October 1994), indicates the contaminants to be below monitoring standards. The Completion Report memorializing the end of Remedial Action was signed by the Regional Administrator on June 30, 1992. The Construction Completion notice was entered into the Federal Register in July 1992. Health Considerations: The site had a potential for recurring fires with toxic air emissions which had the possibly of reaching nearby residences. Other Environmental Risks: Potential of surface discharges along bluff below landfill site. Area is a bald eagle habitat. Previous underground fires have contributed to air releases at the site. Record of Decision Signed: September 27,1987 The remedy selected for the Compass Industries Superfund site includes capping the landfill, with onsite treatment of contaminated ground water, if necessary. Ground Water: Treatment of upper, perched aquifer, if deemed necessary, following installation of the cap. Soil Treatment: Multi-layer cap to confine and isolate landfill contaminants, and to reduce leachate migration into ground water aquifers. Other Remedies Considered 1. "No Action" 2. Cap and off-site ground water treatment 3. Full onsite thermal destruction 4. Partial onsite thermal destruction 5. Partial off-site thermal destruction Reasons Not Chosen Not protective of human health and the environment Increased potential for human exposure to site contaminants Not cost-effective Not cost-effective Not cost-effective COMPASS INDUSTRIES (AVERY DRIVE) December 4, 1995 ------- Community Involvement Community Involvement Plan: Developed 3/84 by EPA, revised 7/90 by PRPs Open houses and workshops: 4/89 (RD Completion), 1/90 (RA Start) Original Proposed Plan Fact Sheet and Public Meeting: 7/87.

The site is currently in a five-year Operations and Maintenance phase to ensure that the site cleanup remedy continues to protect public health and the environment. Monitoring for three-plus years past the cap installation has shown that contaminants of concern are within the cleanup standards. A five year review of the site was concluded in the 4th Quarter of FY95 to evaluate the effectiveness of the remediation based on the monitoring data. Cleanup Measurements American Bald Eagle habitat has been made safer due to remedial efforts. Approximately two stream miles along the Arkansas River have been made safe from offsite migration of contaminants, allowing continued recreational activities by area residents. The potential for site fires spreading airborne contamination to over 300,000 residents of Tulsa has been mitigated. Thirty acres will be returned to recreational/commercial use when the site is delisted.

Based on soil, sludge, and water samples taken in October 1987, EPA proposed the site to the National Priorities List (NPL) in June 1988. Inclusion on tne NPL was finalized in March 1989. EPA sent letters to 453 companies in September 1989 and August 1991 requesting information on their involvement in the Double Eagle facility. Thirteen of these companies are being pursued as potentially responsible parties (PRPs) and have been offered the opportunity to participate in the remedy for the site. EPA began a remedial investigation/feasibility study in March 1990. Studies on the surface wastes were completed in September 1992; studies on the ground water were completed in September 1993. December 4,1995 DOUBLE EAGLE REFINERY COMPANY ------- EPA selected stabilization and offsite disposal as the remedy to address surface contamination in September 1992. The remedy for the Ground Water Operable Unit was selected in April 1994. This remedy included ground water monitoring upon completion of the source removal. Records identifying 46 new potentially responsible parties were found in the Oklahoma State Department of Health archives in October 1992. These records also indicated that listed hazardous wastes (trichloroethylene) were shipped to the site at one time. Because disposal of listed hazardous wastes was not included in the selected remedy, EPA must follow administrative procedures to prove that the waste can be disposed as a non-hazardous material. EPA is currently developing data necessary to complete a petition to delist the waste at the site, allowing the original remedy to be implemented. EPA has completed the design of the ground water monitoring system. Installation of the system will be contracted out in Fall 1995. Design work to address the surface waste has been delayed until the listed waste issue is resolved. Health Considerations: Direct contact threat from lead contaminated sludge and soil.

As part of the selected remedy, offsite disposal of the waste would take place at a RCRA Subtitle D facility. Subtitle D facilities are not permitted for disposal of listed hazardous wastes. EPA has three options to address the hazardous waste issue: 1) disposal at a facility permitted for hazardous waste (double the cost of the selected remedy); 2) disposal of all waste onsite (not supported by the community); or 3) prove that the waste is not hazardous and administratively "delist" the material. EPA has chosen to pursue administrative "delisting" of the waste. The delisting petition is expected to be completed in January 1996. This approach has been supported by both the State of Oklahoma and the residents in the area of the site. Cleanup Measurements Once completed, the remedy selected for the Double Eagle Refining Co. site will mitigate risks from 43 ,000 cubic yards of contaminated sludge for approximately 32,000 people living within three miles of the site.

From June 1985 through December 1987, EPA performed sampling at the site, which indicated elevated levels of several pesticides, acid-based neutral compounds, and volatile organic compounds in soil/sediment and sludge. EPA proposed the site for inclusion on the National Priorities List in October 1987. In March 1989, the site was included on the National Priorities List. EPA was unable to locate any viable Potentially Responsible Parties (PRPs) to participate in the remedial investigation. On October 6, 1989, EPA notified the current landowners that they would not be pursued as PRPs parties (as innocent landowners) and began a remedial investigation. EPA completed its investigation of the surface wastes in May 1992 and its investigations of ground water in the area in June 1993. EPA selected a remedy for the surface wastes in September 1992, which included stabilization and offsite disposal. EPA selected a remedy for the ground water operable unit on September 30,1993, which included monitoring to ensure protection of the lower aquifer. EPA has completed remedial design work for both the surface waste material and the installation of a ground water monitoring system. Contracts for implementation of the surface remedy have been executed and field work began in April 1995. Contracts for the ground water remedy will be executed in Fall 1995.

The site was divided into source control and management of migration operable units in 1985. The Hardage Steering Committee (HSC), a group of potentially responsible parties (PRPs) performed studies on site from fall 1986 through 1988, proposing a cap and slurry wall contrary to EPA's ROD. December 4, 1995 HARDAGE/CRINER ------- September - November 1987, the Potentially Responsible Party (PRP), with EPA oversight, provided an alternate water supply to residents southwest of the site. March 1988, PRP erected a fence at the site to restnct public access. Court opinions on liability, past costs and remedy were rendered August 9, 1990. Liability and past costs were decided in favor of the United States while the court selected the PRP proposed remedy. The liable parties have filed appeals over past costs and one party is appealing its liability. Health Considerations: Contamination of surface water, ground water, and surface soils has been documented. Potential for human exposure via direct contact, ingestion of contaminated soils, and inhalation of contaminants. Other Environmental Risks: Contaminant seeps have been documented on site and are covered when found. Seeps in the borrow pit area have forced the PRPs to investigate additional methods for collecting ground water for treatment and deep well injection. Record of Decision Signed: November 22,1989 Opposed by ODEQ and PRPs The Hardage Record Of Decision (ROD) was signed in November 1989, just prior to the trial. However, both the ODEQ and the PRP group, the Hardage Steering Committee, opposed the EPA chosen remedy. The issue was decided in Federal District Court in favor of the HSC. The project has moved forward under a court-ordered remedy in lieu of a traditional ROD. The remedy is split into two operable units, one for source control and the second for ground water migrating offsite. Source Control: Institutional Controls to restrict access. Recovery of all pumpable liquids. Separation of the phases recovered by an onsite separation system. Offsite incineration of the phases recovered. Eventual cap of the source area. HARDAGE/CRINER December 4. 1995 ------- Ground Water Recoveiy of ground water migrating through the source area via a large trench.

HSRC states that bottom layer in source area showing more solid than liquid properties and that recovery of this substance is "ultra hazardous" due to the recovery process. 3. Discharge to North Criner Creek: at the request of OSDH, HSRC is petitioning for a change to the order allowing for deep well injection rather than discharge to the creek. Cleanup Measurements The initial actions taken by the PRPs to excavate or decontaminate soils and cap the source areas as described above have reduced the potential exposure of nearby residents to site wastes. Additional protective activities include monitoring of attenuation i" down-gradient wells, tracking the volume of contaminants recovered and incinerated, and tracking the volume of water recovered from trench and water wells.

An estimated 57,000 people, including residents of Spencer and Midwest City, obtain drinking water from public and private wells within three miles of the site. Setting: The landfill covers approximately 72 acres. "Pesticides, industrial solvents, sludges, waste chemicals, and emulsions were deposited into three unlined pits. The pits are covered with approximately 80 feet of solid refuse and fill and a clay cap. Hydrology: Two interconnected aquifers are present beneath the site; the upper aquifer is associated with alluvial deposits of the North Canadian River and the lower one is associated with the Garber-Wellington Formation. The Garber-Wellington Formation is a primary ground water resource for the area. The combined aquifers range from 300 to 900 feet thick, with moderate to low permeability. Ground water is shallow (10 to 20 feet) and soils moderately permeable, which facilitates movement of contaminants into ground water. Wastes and Volumes The principal contaminants at the Mosley Road site include industrial hazardous wastes deposited into three unlined, onsite pits, and benzene and vinyl chloride found in the ground water. Approximately two million gallons of industrial wastes were disposed into the onsite pits while the landfill was operating.

Site Map and Diagram East Oak Santtafy Landfill Oklahoma City Mosley Road Landfill The Remediation Process Site History: From February 20 through August 24,1975, the site accepted approximately two million gallons of primarily liquid hazardous waste in three unlined pits near the landfill's base. December 4, 1995 MOSLEY ROAD SANITARY LANDFILL ------- This was permitted by the Oklahoma State Department of Health (OSDH), now Oklahoma Department of Environmental Quality (ODEQ), under a Temporary Emergency Waiver for Hazardous Waste Disposal on February 20, 1976. The Temporary Emergency Waiver expired August 24, 1976. In 1988, a clay cap was placed on the landfill. On July 28,1989, EPA, Waste Management of Oklahoma, Inc., and Mobile Waste Controls, Inc., entered into an Administrative Order on Consent for performance of the Remedial Investigation and Feasibility Study (RI/FS). Health Considerations: Ground water is a significant source of drinking water in the area. Given the hydrogeology of the site, there is significant potential for ground water contamination. Record of Decision Signed: June 29,1992 J Ground Water: Restoration of ground water as a potential source of drinking water through natural attenuation. Continued ground water monitoring to determine if current conditions improve through time, remain constant, or worsen. Monitoring of leachate migration via ground water monitoring and periodic sampling Implementation of active ground water remediation contingencies if triggered by the contingency measure criteria.

An estimated 1,700 students attend schools, and 170 people work at schools and day care centers within three miles of the site. Setting: The site area is a mixed residential, commercial, and industrial area. The contaminated area is approximately 8 square miles. The source of contamination is a zinc smelter of approximately 150 acres. Air dispersion of heavy metals, including lead and cadmium, and community fill projects using smelter slag. Hydrology: The site is characterized by a surface of silt and sandy loam. Subsurface formations consist of shale, siltstone, sandstone, and limestone. No ground water contamination issues exist at this time. Wastes and Volumes The principal pollutants at the site include: The total volumes of these wastes are undetermined at this time. (PPM = Parts Per Million) Lead (soil): Cadmium (soil): 12,000 ppm 1,400 ppm Site Assessment and Ranking NPL LISTING HISTORY Site HRS Score: 5O.OO Proposed Date: 5/10/93 Final Date: Pending NPL Update: Nto. 14 December 4. 1995 ------- Site Map and Diagram National Zinc Facility The Remediation Process Site History: Zinc smelting operations have been conducted at the smelter site since 1907. Air emissions were uncontrolled until 1976, when the old retort-type smelter was replaced by an electrolytic smelting process. The pre-1976 operations are presumably the source of the widespread contaminations at the site. A significant amount of contamination resulted from the use of "lag material and other smelter waste in fill projects in the area. Superfund is addressing the contamination outside of the Zinc Corporation of America facility, the current owner, and contamination within the facility fence is being addressed under authority of the Resource Conservation and Recovery Act (RCP.A). - A removal action addressed contamination in 29 high access or public access areas (schools, day care facilities, playgrounds, etc.) in fall 1992. A removal action in 1993 addressed 22 residences of individuals with elevated blood lead levels. Soil contaminated with lead above 500 parts per million (ppm), and with cadmium above 30 ppm, was excavated and removed. The excavated areas were back-filled with clean soil and re-vegetated. The State of Oklahoma selected a remedy in December 1994 including excavation and offsite disposal of soil from residential properties and a mixture of approaches for commercial properties. December 4.1995 NATIONAL ZINC COMPANY ------- Health Considerations: Blood lead studies funded by Agency for Toxic Substances Disease Registry (ATSDR) and performed by Oklahoma State Department of Health (OSDJH), (now Oklahoma Department of Environmental Quality (ODEQ)), in 1991 and 1992 indicate that approximately 14% of the children in the contaminated area have elevated blood lead greater than 10 micrograms per deciliter (ug/dl). The study revealed that children on the west side of Bartlesville, the side where the facility is located, had elevated levels of blood lead whereas the children on the east side did not. Record of Decision Signed: December 13, 1994 A Record of Decision (ROD) was signed by the State of Oklahoma on December 13, 1994. The selected remedy included: (1) replacement of soil on residential properties with greater than 925 ppm lead, 100 ppm cadmium, and 60 ppm arsenic; (2) Contaminated soil at commercial properties will be addressed through a combination of capping, replacement, tilling, and phosphate treatment.

One PRP agreed to conduct the remedial action under a consent agreement with the State. Present Status and Issues In 1992, the site was selected as a SACM (Superfund Accelerated Cleanup Model) pilot project. Within one year, 29 removal actions had been completed, over 4,000 soil samples had been taken to characterize a 36 square mile area, and a blood lead study had been completed showing elevated levels of blood lead associated with elevated soil lead levels. In 1993, at the request of elected representatives, community leaders, and potentially responsible parties, EPA agreed to allow the State and PRP's to carry out accelerated investigations and residential soil removal actions. In return, EPA would postpone final action regarding placement of the site on the National Priorities List. A ROD for the site was issued in December 1994. In March 1995, the responsible parties began the second year of removal activities to address highly contaminated soils at residential properties. Concurrently, the PRPs and the State of Oklahoma entered an agreement for the implementation of the selected remedy on August 7, 1995. At this time, the EPA removal activities ceased and State-lead remedial action began. Cleanup Measurements In 1994 and 1995 contaminated soil was removed from approximately 400 residential properties by the potentially responsible parties under an EPA Unilateral Admininstative Order. A similar pace for residential cleanup is planned for the State-lead remedial action. Approximately 1500 residential properties remained to be cleaned up to eliminate exposure to to lead contaminated soils.

During operaf'on, Oklahoma Refining Company placed process wastes, including some RCRA Subtitle C wastes, into pits (many unlined). A land farming operation was also run. Leachate from site, possibly threatening the creeks, was observed in 1981. September 1990, EPA started removal activities that included: closure of twenty-three abandoned wells, offsite disposal of 18 drums of hazardous waste, installation of netting over API separator pits to protect wildlife, and construction and repair of perimeter fence. These activities were completed in June 1992. The State of Oklahoma began a remedial investigation/feasibility study in November 1990 to evaluate the extent and magnitude of contamination at the site. Based on these investigations, EPA selected biological treatment of the wastes in a Record of Decision in June 1992. Health Considerations: Direct contact exposure upon redevelopment of the property. Contaminated water discharging to Gladys Creek Record of Decision Signed: June 9,1992 Ground Water: Containment of contaminated ground water to prevent discharge into adjacent creek.

OKLAHOMA REFINING COMPANY December 4, 1995 ------- ------- SAND SPRINGS PETROCHEMICAL COMPLEX OKLAHOMA EPA ID# OKD980748446 EPA REQION 6 CONGRESSIONAL DISTRICT 01 Tulsa County Sand Springs Site Description Location: The site is at the location of the Old Sinclair Refinery in Sand Springs, west of Tulsa, Tulsa County, Oklahoma, adjacent to the Arkansas River. Population: " The population of the greater Tulsa metropolitan area is 376,000; the population of Sand Springs is approximately 15,000. Setting: Nearest residence is within 1/2 mile. Drinking water wells in use are within 1/2-mile of site, although upgradient. The site encompasses approximately 200 acres and includes 2 unlined acid sludge pits (about 10 feet deep), and an abandoned solvents and waste oil recycling facility. Geology: The Sand Springs Superfund site is underlain by approximately 30 feet of sand, which is underlain by shale. Shale thickness appears to exceed 100 feet. An alluvial aquifer beneath the site appears to flow toward the Arkansas River. Wastes and Volumes Principal pollutants at the site are found in several media: - Ground water: 1,1,1-trichloroethylene, 36 ppm (parts per million) 1,1-dichloroethene, 6 ppm - Sediments: trichloroethylene, 700 ppb (parts per billion) - Acid pits waste: hydrocarbons and mineral acids, in the percent level The estimated waste volume for the sludge pits is 125,000 cubic yards; for the Glen Wynn facility is 5,000 cubic yards of sludge and contaminated soils.

ARCO also believed a score of 45 for observed release to surface water was unwarranted. A drum and tank removal was performed 3/84 by the PRPs under an Administrative Order. Site Map and Diagram SAND SPRINGS December 4. 1995 SAND SPRINGS PETROCHEMICAL COMPLEX ------- The Remediation Process Stte History: "-'- ' *'£ The Sand Springs site operated as a refinery from the turn of the century through late 1940s. The site has since been developed as an industrial area consisting of chemical manufacturers, solvent recovery operations, a transformer salvage/recycler and various other industries. August 1984, with EPA oversight, some of the (PRPs) removed drums and tanks from the site. EPA removed 400 drums of hazardous material, repaired the fence, sampled and analyzed pits, on site soil, and on site monitoring wells. The State of Oklahoma conducted the remedial investigation/feasibility study (RI/FS). Chemical solidification/stabilization (CSS) treatability studies were conducted 9-10/91. EPA and Oklahoma State Department of Health (OSDH) (now Oklahoma Department of Environmental Qualaity (ODEQ)) evaluated CSS data and reviewed CSS and incineration preliminary designs in Spring 1992. August 1992 - Glenn Wynn remediation initiated; completed November 1992. October 1992 - EPA/ODEQ reviewed of CSS Technology Selection Report. February 1993 - CSS selected as site remedy. June 1993 commenced landfill construction. April 1994, CSS treatment of waste began. January 1995-complete excavation and neutralization of all waste at site. August 1995 treatment complete and landfill closed. August 29,1995, Remedial Action Completion Ceremony held. Health Considerations: Potential direct contact with acid sludge pits and surface impoundments. Other Environmental Risks: Contamination of ground water is possible from the pits. Surface water has been contaminated. Record of Decision Signed: September 29,1987 (Source) September 28, 1988 (Ground Water) The Source Control Record Of Decision (ROD) addressed the Glen Wynn facility and selected incineration of sludge from pits as a remedy, with solidification of remaining wastes if proven equally environmentally effective as incineration during the Remedial Design. This ROD addressed all surface liquids, sludges, and heavily contaminated soils (within EPA's removal criteria). Ground Water This aspect of the site was addressed in another ROD signed on 6/28/88, which chose "No Action" on the minimally contaminated soil or ground water with long-term monitoring following completion of the Source Control Operable Unit. SAND SPRINGS PETROCHEMICAL COMPLEX December 4, 1995 ------- Soli Treatment: After reviewing all available information, EPA judged that onsite thermal destruction (incineration) of wastes appears to meet more statutory selection criteria than the other remedies evaluated, but has significant implementation problems. During the public comment period, ARCO Petroleum Products Company, one of the PRPs for this site, made written and verbal proposals for a privately financed remedy for the site. The most effective of the ARCO proposals provides for: 1) The excavation and off site thermal destruction of sludges, at least to the sludge/soil interface from the portion of the site identified as the North and South Glen Wynn Lagoons. 2) Solidification and/or stabilization of all remaining sludges and containment of the resulting matrix in a hazardous waste Resource Conservation and Recovery Act (RCRA) cell to be constructed onsite. This cell (or cells) is to meet the minimal technological requirements of subtitle C of the Solid Waste Disposal Act. 3) As part of the Remedial Design, ARCO will demonstrate that the solidification technology will meet EPA approved criteria. This criteria will include both chemical and physical testing requirements. Should the solidification technology fail these criteria, thermal destruction will be employed as the remedy for the above mentioned operable unit. 4) There will be no liability release for the site or from future maintenance and monitoring. 5) Repair or restoration of the RCRA cell to ensure no migration from the unit or destruction or treatment of all or a portion of its contents, as EPA deems appropriate, should monitoring show that the solidification and/or stabilization remedy fails.

SAND SPRINGS PETROCHEMICAL COMPLEX December 4, 1995 ------- Present Status and Issues The immediate actions undertaken to remove contaminated drums and tanks and to repair the fence surrounding the site reduced the exposure potential at the Sand Springs Petrochemical Complex site while cleanup activities took place. Chemical Solidification/Stabilization (CSS) was selected as the site remedy in February 1993. Landfill construction began November 1993; site preparation began July 1993. CSS remediation began May 1994, and treatment was completed in July 1995. Cap installation began April 1995. The asphalt recycling demonstration began in early April 1995, and work was completed by June 1995. Landfill closure took place on August 10,1995. The construction completion ribbon cutting took place on August 29,1995. Glenn Wynn remediation was completed per the Consent Decree Statement of Work. Cleanup Measurements Through the work of EPA, ODEQ and the PRPs, the cleanup at the Sand Springs Petrochemical Complex mitigated environmental risks from 208,000 cubic yards of contaminated soils, sludge, concrete and debris by placing it in a Resource Conservation and Recovery Act Title C onsite landfill, and made several miles of the Arkansas River safer for recreation uses.

Mines abandoned in 1970, began filling with ground water. Highly acidic mine water containing high concentration of heavy metals began discharging into Tar Creek in 1979 from natural springs, bore holes, and abandoned mine shafts. A remedial investigation was conducted in 1982 and 1983 resulting in a Record of Decision (ROD) in June 1984. Roubidoux aquifer monitoring report completed 12/93. August - October 1985, an emergency water supply was put in place by the National Guard. EPA plugged the contaminated well, drilled a new well and flushed city lines. Water quality returned to normal; National Guard discontinued water delivery. December 1986, construction of the ROD remedy was completed. April 1994, a Five Year Review of the remedy was issued. New studies to evaluate mining waste, not addressed in the original remedy, as a source of contamination began in Fall 1994. Iron levels in drinking water from 5 community wells in the mining area are elevated above secondary standards. The Oklahoma Department of Environmental Quality (ODEQ) is investigating to determine if the Roubidoux Aquifer is the source of the contamination. A summary of results of Indian Health Service testing made available to EPA in 1994 indicated that approximately 35% of the Indian children tested in the area had blood lead levels greater than 10 ug/dL, the level that is considered elevated. EPA investigated 28 high access areas (day cares, schools, parks, and similar areas where children tend to congregate) in Fall 1994 for mining waste contamination. Approximately 40% of the high access area (HAA) samples contained lead greater than 500 ppm. The Oklahoma Department of Health completed the screening of children in the mining area for blood lead poisoning in October 1995. In the Picher-Cardin area, the heart of the mining area, 21 percent of the children had elevated blood lead levels. Remedial investigation and feasibility study (RI/FS) work plans for the mining waste were completed by the Army Corps of Engineers in July 1995. EPA completed sampling soil at approximately 2,000 residences in the mining area for lead and cadmium contamination in August 1995. EPA is evaluating the residential sampling data and preparing the baseline human health risk assessment. The PRPs will be issued Special Notice for the residential RI/FS and remedial design (RD) in November 1995. Plans are being developed for a residential soil removal action in the highest priority yards to begin in the Spring 1996. Health Considerations: The lower aquifer serves several towns and rural communities in Ottawa County and is threatened due to several bore holes and leaking abandoned wells connecting the aquifer. Eighty-three of these bore holes were plugged in 1986 to prevent migration to the Roubidoux. Current public water supply monitoring indicates that primary drinking water standards are not being exceeded in the Tar Creek area. TAR CREEK (OTTAWA COUNTY) December 5, 1995 ------- Other Environmental Risks: High concentrations of heavy metals have been discharged to the surface water. The shallow Boone Formation aquifer has been contaminated with heavy metals. Lead contamination in surface soils is a source of exposure to children living in the area. Record of Decision Signed: June 6,1984 Remedy signed as complete 12/86. The remedy included diversion and diking of two major inflow areas in Kansas and one potential inflow area in Oklahoma. Plugging 83 identified abandoned wells in the Roubidoux aquifer, and any other abandoned wells found connecting the Roubidoux. Monitoring plan to monitor contamination of the Roubidoux aquifer and Tar Creek. Other Remedies Considered 1. Collection and treatment of mine water 2. In SHu treatment of mine water 3. Surface discharge treatment 4. Alternative drinking water 5. No action Rationale for Dismissal Very expensive ($30M) and probably Ineffective. Very expense ($30M) plus technical infeaslblllty. Would only capture a portion of the discharge at excessive expense. More expensive ($6M) Environmentally unacceptable.

The 6 defendants and signatories to the Decree were 1) ASARCO, Inc.; 2) Blue Tee Corporation; 3) Childress Royalty Company; 4) Gold Fields Mining Corp.; 5) NL Industries, Inc.; and 6) St. Joe Minerals Corporation. Present Status and Issues A Phase II Ground Water Monitoring project is being planned by ODEQ for the Summer 1996. The purpose of the monitoring is to determine the source of contamination in the 5 community wells that do not meet secondary drinking water standards. Sampling data from residential areas are being evaluated for a possible soil removal action. A report of studies to evaluate blood-lead levels in area children will be completed in late Fall 1995. Studies are being conducted by the Oklahoma State Department of Health and local health departments. Approximately 50 per cent of the land in the Oklahoma portion of the mining district is owned by the Quapaw tribe. Remedial actions on these lands are not subject to the cost share provisions of Superfund. In addition to the parties that settled with EPA in 1991, the U.S. Department of the Interior may be a responsible party at Tar Creek. Negotiations with the PRPs are underway. An Action Memorandum to address the HAAs was signed on August 15,1995. The soil removal work began September 15, 1995 and is scheduled for completion in December 1995. The removal consists of the excavation and disposal of soil from HAAs contaminated with lead and cadmium. The disposal area is located on-site in a mill tailings pond. The removal action/cleanup levels are 500 parts per million (ppm) lead and 100 ppm cadmium. TAR CREEK (OTTAWA COUNTY) December 5, 1995 ------- Cleanup Measurements Actions by the State of Oklahoma and the EPA have reduced the potential for contaminants in the shallow ground water to migrate to deeper drinking water aquifers and have achieved the ground water cleanup standards established for the site. The State also has completed cleanup activities at the Tar Creek (Ottawa County) site for surface water improvement. Several miles of stream diversion reduces inflow to mines. The Removal Action to address the 28 HAAs has been completed at all but two properties.

In August 1985, EPA removed drums of solvents and oils, removed junk cars, regraded and placed a temporary cap on the site, fenced the site, and posting warning signs. No PRPs were found; EPA conducted an RI/FS from October 1988 through September 1990. EPA re-evaluated the remedy due to technical problems with dechlorination. A new remedy was selected in Summer 1993, including containment of PCB-contaminated soil in place (in-situ) by constructing a permanent cap over the site. The Army Corps of Engineers completed design of the remedy in the Fall of 1994. Remedial action, capping in place, began April 1995 and will be completed in the Winter 1996. December 5, 1995 TENTH STREET DUMP/ JUNKYARD ------- Health Considerations: Potential tor direct contact with contaminated soils onsite and migration due to erosion of site soils. Record of Decision Signed: September 28,1990 Amended: September 30,1993 Original remedy included onsite Chemical Dechlorination and disposal onsite of the treated material. Amended remedy replaced chemical dechlorination with onsite capping. Other Remedies Considered Reason Not Chosen 1. No action 2. On-sHe Incineration 3. Offsfte Incineration 4. Offsite Land Disposal 5. Capping Not adequately protective, does address contaminants above 25 ppm PCBs. More costly than proposed plan without significantly higher benefits. Order of magnitude higher cost than other alternatives. Not a treatment alternative; costs are similar to treatment alternatives. Site in 100-year floodplain; does not eliminate long-term maintenance or reduce toxlclty or volume of waste. Capping was re-selected as site remedy In September 1993; ROD amended In 1990 due to failure of dechlorination at other site and reluctance of State to provide 10% matching funds.
