Approval of a Petition for Exemption from Hazardous Waste Disposal Injection Restrictions to Cabot Corporation Tuscola, Tuscola, IL

摘要

Notice is hereby given by the United States Environmental Protection Agency (EPA) that an exemption to the land disposal restrictions under the 1984 Hazardous and Solid Waste Amendments (HSWA) to the Resource Conservation and Recovery Act (RCRA) has been granted to Cabot Corporation Tuscola Plant (Cabot Corporation) of Tuscola, Illinois, for two Class I injection wells located in Tuscola, Illinois. As required by 40 CFR part 148, Cabot Corporation has demonstrated, to a reasonable degree of certainty, that there will be no migration of hazardous constituents out of the injection zone or into an underground source of drinking water (USDW) for at least 10,000 years. This final decision allows the continued underground injection by Cabot Corporation of specific restricted wastes from the silica production processes (codes D002, F003, and F039 under 40 CFR part 261), into two Class I hazardous waste injection wells specifically identified as Injection Wells No. 2 and No. 3 at the Tuscola facility. This decision constitutes a final EPA action for which there is no Administrative Appeal.
