ABSTRACT The site, which is approximately one-quarter acre in size, was used originally for storage of heating oil and gasoline. The site was purchased in 1972 by a waste disposal firm that used the underground tanks to store a variety of liquid and hazardous wastes. EPA analysis of the tank contents identified a wide variety of organic and inorganic chemicals, including benzene, methylene chloride, toluene, arsenic •, chromium, and nickel. The cost-effective initial remedial measures (IRM) selected for this site include cleaning and removal of underground waste storage tanks and excavating and off-site disposal visibly contaminated soil. Additional soil analyses will be performed to determine if further site action is necessary. The estimated cost for this IRM is approximately $114,500. 17.

Visibly contaminated soil will be excavated for offsite disposal, and soil samples will be taken for laboratory analysis. A supplemental ROD will be prepared after the results of the soil samples have been evaluated. The supplemental ROD will include a recommendation for further sit3 action, or for no action. Declarations Consistent with the Comprehensive Environmental Response, Compensation and Liability Act of 1980, and the National Oil and Hazardous Substances Contingency Plan, I have determined that removing the underground tanks and excavating or encapsulating potentially contaminated soil are appropriate Initial Remedial ------- Measures for the problems at this site. The inltial remedial measures described above are feasible, cost-effective,"and necessary to limit the exposure or threat of exposure to a significant health or environmental hazard. Moreover, to the extent that off-site treatment is necessary, it is more cost effectiv~ than other forms of remedial action. 11 ~;t;)?c(:lL Thomas P.

Eichler Regional Administrator ------- " Narrative Summary McAdoo, Blaine Street Site History The underground storage tanks at the Blaine Street Site, in McAdoo, Pennsylvania, were used for a heating oil and gasoline business until 1972. The site, which is approximately one-quarter acre in size, 'was purchased in 1972 by a waste disposal firm called McAdoo ,Associates, PAYSO, Inc. The four underground tanks were used to store a variety of liquid hazardous wastes. The wastes disposal firm also ran an associated facility in Kline Township, adjacent to the Borough, and both sites are referred to as the McAdoo Superfund Project. The disposal firm's activities were stopped in 1979 by the Pennsylvania Department of Environmental Resources. This is the State Priority Site in Pennsylvania. Current Status In 1981, EPA analysis of the tank contents identified a wide variety of organic and inorganic chemicals, including benzene, methylene chloride, toluene"arsenic, chromium and nickel. A statistical ~nalysis of the tanks concluded that there was at least an 80% chance that the tanks had leaked. This conclusion was based'on the nature of local soils, the contents of the tanks, and the age of the tanks. Of "special . concern is the fact that the municipal water supply well for the Borough of McAdoo is within 900 feet of the Blaine Street site. This well serves 1200 local residents, and it is the only municipal well in the area. As a result of negotiations with potentially responsible parti'es, 11,000 gallons 6f waste liquid were pumped from the underground tanks at Blaine Street in July, 1982. These negotiations ended in August, 1983, when the responsible parties informed EPA that they were unwilling to finance any additional work at the site. . The 8No Action8 alternative for this IRM was rejected because of the high probability of tank failure, and the site's proximity to a municipal water supply well. The proposed action includes removal of the tanks and examination of the underlying soil. This is the most effective way of determining the nature and extent of site contamination problems, because it is likely that any leakage from the tanks has migrated vertically, rather than laterally. Such migration would be expected due to the porous nature of the soil and local coal mining activity. -1- ------- . . . State Recommendation After giving careful consideration to the alternatives and to the public comments that were received, the Pennsylvania Department of Environmental Resources also concurs in this recommendation. A letter supporting the State's recommendation appears in Attachment A. Proposed Action We request your approval of the cleaning and removal of underground tanks, the removal of contaminated soil, and the sampling of subsurface soils for the IRM at the McAdoo, Blaine Street Site, and an allocation of $114,500 for this project. Tentative Schedule . Adpublic meeting for this'project initial site work has been completed. take approximately two weeks, and work of project approval. . has already been held, and Removal of the tanks would could begin within a month If you have any questions, please call Eric W.
