AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of Final Decision on No Migration Petition Reissuance.

SUMMARY:

Notice is hereby given that an exemption to the land disposal restrictions under the 1984 Hazardous and Solid Waste Amendments to the Resource Conservation and Recovery Act has been granted to E. I. du Pont de Nemours & Co., Inc. (DuPont) for 11 Class I injection wells located at Victoria, Texas. As required by 40 CFR part 148, the company has adequately demonstrated to the satisfaction of the Environmental Protection Agency by the petition and supporting documentation that, to a reasonable degree of certainty, there will be no migration of hazardous constituents from the injection zone for as long as the waste remains hazardous. This final decision allows the underground injection by DuPont, of the specific restricted hazardous wastes identified in the exemption, into Class I hazardous waste injection wells Nos. WDW-142, WDW-143, WDW-144, WDW-4, WDW-28, WDW-29, WDW-30, WDW-105, WDW-106, WDW-145, WDW-271 at the Victoria, Texas facility, until December 31, 2007, or when starting on January 1, 2001, 4733 million gallons have been injected into the Main Catahoula Sand or 2630 million gallons have been injected into the Lower Catahoula Sand, whichever occurs first, unless EPA moves to terminate the exemption under provisions of 40 CFR 148.24. Additional conditions included in this final decision may be reviewed by contacting the Region 6 Ground Water/UIC Section. As required by 40 CFR 148.22(b) and 124.10, a public notice was issued November 13, 2000. The public comment period closed on December 28, 2000. No comments were received. This decision constitutes final Agency action and there is no Administrative appeal. This decision may be reviewed/appealed in compliance with the Administrative Procedure Act.
