SUPERFUND Records Of Decision Update From: Hazardous Site Control Division To: EPA Regional Offices October 31, 1985 Vol. 1, No. 7 ROD SUMMARIES McKIN SITE, REGION I, MAINE (Approved 7/22/85) Description: After the IRM taken at the site, an incinerator, miscellaneous debris, a lagoon, and a buried fuel tank still remain. Soil and ground water contamination exist at the site. Decision: Aerate contaminated soil mechanically to remove volatiles, dispose of drums and other materials offsite, ex- tract and treat groundwater for a period of up to 5 years, and monitor offsite surface water and ground water. Issues: Restoration of the Class II aquifer and aeration of the soil to remove contaminants were selected over the option of just capping the site. Ground water restoration is preferred whenever possible. Existing data, though limited, were sufficient to support a decision to treat ground water. Ground water performance standards were established in the ROD, but these will be re- evaluated after a maximum of 5 years of system operation and monitoring. Ground water protection ob- jectives were based on a unit carcinogenic risk level of ap- proximately 10-5. This is war- ranted because the aquifer will be continually monitored and because there are currently no private wells withdrawing from the aquifer. The target action levels for soil excavation and treatment by aeration were based on the estimated impact on the underlying aquifer.

Decision: Construct a full synthetic membrane cap over the entire site, and construct a surface water collection system, a leachate collection system, and an off-gas collection system. Issues: Source containment measures were found to be the only viable remedial alternatives as a result of the initial screening phase. Capping the site is an integral component of each source-containment measure. Initiation of capping as a separate operable unit prior to completion of the overall RI/FS will significantly benefit human health and the environ- ment by greatly reducing the amount of leachate generated. Contacts: Region I: Rich Leighton FTS-223-1946 Headquarters: Bill Kaschak FTS-382-2348 LOVE CANAL, REGION II, NEW YORK (Approved 5/6/85) Description: Over 21,000 tons of chemicals, including dioxins, were disposed of in Love Canal by Hooker Chemical and Plastics Corporation between 1942 and 1952. Chemicals at the site in- clude acids, chlorides, mer captans, phenols, toluenes pesticides, chlorophenols chlorobenzenes, and sulfides Contaminants were carried in to streams and sewers by a ris ing water table. Decision: Hydraulically clean and re- move sediments from sanitary and storm sewers and remove contaminated sediments from creeks. Dewater sediments and store in a temporary con- tainment facility to be con- structed on the site. Construct a berm to control sediments near the 102nd Street outfall area (if found consistent with the project plan for the 102nd Street Landfill Superfund site). Continue efforts to identify ------- potential technologies to be used for the permanent remed- iation of the sediments.

Decision: First operable unit Relocate residents permanently. Contacts: Region III: Walt Graham FTS-597-9387 Headquarters: Linda Boornazian FTS-382-7997 TAYLOR BOROUGH, REGION III, PENNSYLVANIA (Approved 6/28/85) Description: Municipal landfilling and dis- posal of drummed industrial wastes occurred after the site had been used as a mine. Decision: Dispose of drums offsite and underlying soils and sedi- ments to background levels in pond areas #1 and #2. Con- struct a soil cover for the drum storage. Issues: Mine subsidence prevents a RCRA cap. Remediation on ground water was deferred. All ground water migrates vertically to the mine pool. Only the portion of the site where drum disposal occurred will be cleared.

Contacts: Region IV: Jack Snider FTS-257-2930 Headquarters: Ed Barth FTS-382-7998 KUMMER LANDFILL, REGION V, MINNESOTA (Approved 6/12/85) Description: A 40-acre municipal and indus- trial waste landfill is con- taminating ground water with volatile organics. Ground water is used as a drinking water supply. Decision: Build two new alternate water supply wells, a new water tower, and a distribution system. No decision on ground water restoration. Contacts: Region V: Allen Wojtas FTS-886-6941 Headquarters: Kitty Taimi FTS-382-2449 McADOO ASSOCIATES, REGION III, PENNSYLVANIA (Approved 6/28/85) Description: The site was used for deep and strip mining and was later used as a metals reclamation operation. Wastes include paint sludge, solvents, metallic sludge, acids, caustics, and others. Decision: Remove tank and debris. Ex- cavate a limited amount of soil and dispose offsite. Cap site, and divert surface water. Contacts: Region III: Dom Digiulio FTS-597-3435 Headquarters: Linda Boornazian FTS-382-7997 WHITEHOUSE WASTE OIL PITS REGION IV, FLORIDA (Approved 5/30/85) Description: The site includes seven unlin- ed pits containing waste oil sludge, acids, and con- taminated waste oil. Decision: Construct a slurry wall around site, place all contaminated stream sediments within slurry wall, provide long-term extraction and treatment of ground water within slurry wall, and cap entire area. Issues: Placing contaminated sedi- ments within the slurry wall consolidates wastes. Long- term ground water extraction creates a negative hydraulic gradient and has greater durability. This remedy is ex- pected to minimize the possibility of further plume migration outside the slurry CROSS BROTHERS, REGION V, ILLINOIS (Approved 3/25/85) Description: A former container reclama- tion process on site allowed indiscriminant dumping of dyes, paints, inks, and solvents on 20 acres of land. Decision: Dispose of waste materials and contaminated soil offsite. Issues: "Visibly contaminated soil" as a criterion for removal could still be used as of March 1985, but it is no longer recommend- ed even for interim measures. Contacts: Region V: Dan Capice FTS-886-0397 Headquarters: Kitty Taimi FTS-382-2449 ------- SOUTH VALLEY, REGION VI, NEW MEXICO (Approved 3/22/85) Description: Organic chemicals have been stored and used in the South Valley for over 20 years. Organic contamination has been found in two of the municipal wells that supply drinking water for the City of Albuquerque. Investigations to date indicate area-wide ground water con- tamination. Decision: Install a new water supply well for the City of Albuquerque. Perform additional offsite and source control remedial in- vestigations to develop an overall cleanup strategy for the area-wide ground water con- tamination. Contacts: Region VI: David McCartney FTS-729-9741 Headquarters: Randall Kaltreider FTS-382-2448 JIBBOOM JUNKYARD, REGION IX, CALIFORNIA (Approved 5/9/85) Description: The 9-acre site was used for metal salvaging (including transformer disassembly), which resulted in heavy metal and low-level PCB contamina- tion. Portions of the site are now covered by an interstate highway embankment. Decision: Excavate and dispose of un- covered, contaminated soil offsite, using an action level of 500 ppm lead. Issues: The action level for lead con- centrations was initially selected to be the background level of 200 ppm. Later, the ROD was amended to incor- porate a health-risk-based ac- tion level of 500 ppm lead. Contacts: Region IX: Nick Morgan FTS-454-8918 Headquarters: Steve Hooper FTS-475-6689 TACOMA WELL 12A, REGION X, WASHINGTON (Approved 5/3/85) Description: Surface soils and ground water are contaminated with organic solvents. Ground water contamination extends for about 2,000 feet downgra- dient to municipal well 12A and other water supply wells that draw water from the con- taminated aquifer. In 1983, an IRM was taken to convert municipal well 12A into a blocking well to prevent fur- ther plume migration into the well field. Decision: Continue treating municipal well 12A effluent (approved as an IRM in 1983) as long as necessary. Extract and treat contaminated ground water at the source area and discharge into the bay. Do further sampling to deter- mine extent of soil contamina- tion. Excavate and remove heavily contaminated surficial soils. Treat deeper soils in situ by means of downward flush- ing with water and by vacuum extraction. With institutional controls, limit use of contaminated ground water by private par- ties. Re-evaluate ground water treatment system after 2 years of operation to determine ef- fectiveness and consider closeout requirements. Contacts: Region X: Pat Storm FTS-399-1099 Headquarters: Steve Hooper FTS-475-6689 MORRIS ARSENIC, REGION V, MINNESOTA (Approved 8/7/85) Description: About 1,500 pounds of arsenic- laced grasshopper bait was buried in a gravel pit. A highway has since been con- structed through the site. Decision: No action will be taken because there is no significant health hazard. Levels of arsenic found in the soils and ground water are below the MCL for arsenic and below an advisory level for soils. Arsenic is not migrating in ground water or soil. Contacts: Region V: Gene Wong FTS-353-6341 Headquarters: Carol Lindsay FTS-475-6704 OLD MILL, REGION V, OHIO (Approved 8/7/85) Description: The site was used for drum storage and waste disposal. Wastes include solvents, oils, resins, PCBs, and other chemicals. The drums have been removed, but con- taminated soil and ground water remain. Decision: Dispose of contaminated soil offsite, extract and treat ground water, restrict use of aquifer, and provide an alter- nate water supply. Issues: Soil removal for some com- pounds was chosen to be completed at a unit carcino- genic risk level of 10 6. Ninety- five percent of contaminant mass will be removed. Removal of all soils con- taminated above background level would have increased the volume of the removal by four times. Target levels for ground water equate to a risk level of 10-5 VCR. It is assumed that it will take 30 years of treatment to reach this target and 100 years before the concentration reaches the 10-6 risk level. During this time, aquifer use will be restricted. ------- Contacts: Region V: Mary Tyson FTS-886-3006 Headquarters: Carol Lindsay FTS-475-6704 MAIN STREET, REGION V, INDIANA (Approved 8/2/85) Description: Volatile organic compounds, primarily TCE, were found in drinking water from the Main Street Well Field. This source supplies 70 to 80 percent of the City's water needs. Decision: First operable unit Intercept and treat contaminated ground water with an air strip- ping system. Water supplied to the town will be designed to meet 10 6 unit carcinogenic risk levels. Contacts'. Region V: Mike Strimbu FTS-353-6417 Headquarters: Carol Lindsay FTS-475-6704 ELLISVILLE, REGION VII, MISSOURI (Approved 7/10/85) Description: The site includes three proper- ties. The Callahan and the Rosalie properties are includ- ed in this ROD. Liquid and solid wastes, including solvents, sludges, pesticides, and flammable materials, were dumped. Decision: Callahan site Stabilize the fill area. Rosalie site Dispose of con- taminated soil, drums, and other debris offsite; conduct soil testing. Issues: Rather than establishing ac- tion levels, CDC will determine (through repeated soil sample analyses) when the Rosalie site no longer poses a threat. Contacts: Region VII: Bob Field FTS-758-3931 Headquarters: Elizabeth Ertel Hall FTS-382-2451 SCHMALZ DUMP, REGION V, WISCONSIN (Approved 8/12/85) Description: Site consists of 5 acres of wet- land used for the disposal of industrial wastes, utility fly and bottom ash, and demoli- tion debris contaminated with PCBs. Decision: Dredge 3,500 cubic yards of PCB-contaminated building debris and soil and dispose offsite. Contacts: Region V: Margaret Guerriero FTS-886-0399 Headquarters: Carol Lindsay FTS-475-6704 EAU CLAIRE, REGION V WISCONSIN - IRM (Approved 6/10/85) Description: VOCs were found in drinking water from the Eau Claire Municipal Well Field, which serves 57,500 residents. Decision: Remove VOCs from ground water by air stripping, and dis- charge treated water into the municipal water treatment plant. Contacts: Region V: Joan Calabrese FTS-886-0403 Headquarters: Carol Lindsay FTS-475-6704 TRIANGLE CHEMICAL, REGION VI, TEXAS (Approved 6/11/85) Description: Raw materials and finished products from the production of various industrial cleaning compounds, brake fluids, pesticides, and other chemi- cals were stored in bulk sur- face tanks and drums. Decision: Incinerate and deep well inject tank and drum contents, and mechanically aerate contam- inated soils. Contacts: Region VI: Don Williams FTS-729-9713 Headquarters: Ed Barth FTS-382-7998 ------- FY'85 WRAP UP FY'85 was a very good year in the ROD business. A total of 65 RODs and 2 EDDs were signed; 58 of the 64 first operable units RODs targeted for completion made it to signature by September 30. So much practice will come in handy during FY'86, when approximately 90 RODs are expected to be signed.

Any likely compromise of the proposed bills before Congress will ex- pand the scope of cleanup ef- forts dramatically. Once CERCLA is reauthorized, the program will face the dual challenge of rapid expansion and acceleration, both of which must occur without sacrificing the quality of our studies and remedies. To help achieve these difficult objectives, HSCD will be imple- menting the Remedial Improve- ment Pilot Program. Over the next 3 months, HSCD will be working with the Regions to select candidate sites and begin a series of pilot projects in the following categories: phased RI/FSs; enhanced contractor continuity; expedited response actions; site-specific contrac- ting for remedial planning; and improved program planning, monitoring, and control. A steer- ing committee with representa- tion from Headquarters and the Regions has been organized to assist HSCD in monitoring the pilot projects and evaluating the success of the various options. Three areas of special focus for the coming year will be the use of alternative technologies, the use of removal authorities as part of a remedial response, and continuing efforts to clarify the RCRA/CERCLA interface. ------- A LINE ON RODs NEW SECTION CHIEFS HSCD recently named three new section chiefs. In the Remedial Action and Contracts Branch, Bill Kaschak is heading up Sec- tion A, where he's responsible for providing policy, technical, and procedural support to Regions I, III, IV, IX, and X. Nancy Willis is the new chief of Section B with responsibility for Regions II, V, VI, VII, and VIII. C. Scott Parrish is the new chief of the National Priorities List Sec- tion of the Discovery and In- vestigation Branch. ROD AVAILABILITY You can now direct members of the public to two sources for RODs. In addition to the Na- tional Technical Information Ser- vice, which sells both hard and microfiche copies, the En- vironmental Law Institute (ELI) now has hard copies of the RODs available for purchase. Although small, ELI is able to process document requests very promptly. ELI is located at: 1616 P Street, NW Suite 200 Washington, D.C. 20036 202-328-5150 ------- |
