SUPERFUND Records Of Decision Update Prom: Hazardous Site Control Division To: EPA Regional Offices December 2,1986 Vol. 2, No. 6 J Superfund Reauthorization On October 17, 1986, the Presi- dent signed the Superfund Amendments and Reauthoriza- tion Act of 1986 (SARA) into law. The act codifies the process and program established in the re- vised National Contingency Plan (NCP) in November 1985 while adding some new provisions and statutory emphasis to por- tions of the program. Most significant for the remedy selec- tion process are the cleanup standards provisions in §121. This section calls for remedial actions that are protective of human health and the environ- ment, that are cost effective, that attain the applicable or rele- vant and appropriate require- ments of other Federal environ- mental statutes and more strin- gent State requirements, and that use permanent solutions and treatment technologies to the maximum extent prac- ticable. Progress in developing implementation guidelines for the cleanup standards will be reported in the months to come. A Line on RODS mmmm ROD Data Base The Office of Emergency and Remedial Response (OERR) and Ihe Office of Information Resources Management (OIRM) have been working together to enter the Superfund remedy selection documents (RODs and EDDs) into BASIS, an automated text search and retrieval system similar to LEXIS, which EPA pur- chased last year. At present, all of the RODs signed from FY'82 through FY'85 have been entered. Plans for institutionaliz- ing this in-house system—con- ducting QA/QC, entering the FY'86 decision documents, training—are under develop- ment. EPA technical, legal, or policy staff interested in becom- ing early users are welcome. All you need is a PC, a modem to patch into the National Com- puter Center at RTP, and a user identification number. To obtain the latter, and for more general information, call Betsy Shaw at FTS 382-3304 FY'86 RECORD OF DECISION (ROD) SUMMARY TABLE The FY'86 Record of Decision Summary Table provides an overview of site problems, selected remedies, cleanup criteria, and estimated costs provided in all RODs signed in FY'86. This table reflects remedial program accomplish- ments in incorporating alter- native technologies into source control remedial actions. Sixty of the 84 RODs signed in FY'86 address source control remedies. Of these 60 RODs, 27 selected alternative technolo- gies (ATs). Incineration was the AT most often selected in FY'86 (39 percent), while solidification was selected 22 percent of the time. These two technologies comprise 61 percent of all ATs selected in FY'86. For one site, Fields Brook, Ohio, both in- cineration and solidification were selected as part of a source control remedial action.
