AGENCY:

Environmental Protection Agency.

ACTION:

Notice of final decision on a 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 & Company, Inc. (DuPont) for Class I injection wells located at Orange, Texas. As required by 40 CFR part 148, the company has adequately demonstrated to the satisfaction of the Environmental Protection Agency by the petition reissuance 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 No. WDW-54, WDW-55, WDW-191 and WDW-282 at the Orange, Texas facility, until December 31, 2020, unless EPA moves to terminate the exemption under provisions of 40 CFR 148.24. As required by 40 CFR 148.22(b) and 124.10, a public notice of the proposed decision was issued December 21, 2000. The public comment period closed on February 5, 2001. No comments were received. This decision constitutes final Agency action.

DATES:

This action was effective as of February 13, 2001.
