Notice of Intent to Reissue an Exemption From the Land Disposal Restrictions of the 1984 Hazardous and Solid Waste Amendments (HSWA) to the Resource Conservation and Recovery Act (RCRA) Regarding Injection of Hazardous Waste to Cabot Corporation

요약

The United States Environmental Protection Agency (EPA or Agency) is today proposing to reissue an exemption from the ban on disposal of certain hazardous wastes through injection wells to Cabot Corporation for its site at Tuscola, Illinois. On November 6, 1990, the Agency issued Cabot an exemption for injection of certain hazardous wastes into Waste Disposal Well (WDW) No. 2 after determining that there is a reasonable degree of certainty that Cabot's injected wastes will not migrate out of the injection zone within the next 10,000 years. On February 4, 1991, Cabot was granted an exemption to allow use of WDW No. 1 at the facility for the disposal of the same wastes injected through the WDW No. 2. The exemption was modified on November 4, 1994, to include monitor well purge water. If granted, the proposed reissuance would allow Cabot to inject the RCRA regulated wastes D002, F003, and F039, which are already injected through WDWs Nos. 1 and 2, through WDW No. 3 and will add information gained as a result of the drilling of WDW No. 3 to the administrative record. WDW No. 1 will be closed after WDW No. 3 is put on line.
