ACTION:

Notice of a final decision on a no migration petition reissuance.

SUMMARY:

Notice is hereby given that a reissuance of 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 INEOS for three Class I hazardous waste injection wells located at their Green Lake Complex located in Port Lavaca, Texas. The company has adequately demonstrated to the satisfaction of the Environmental Protection Agency (EPA) by the petition reissuance application 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 INEOS, of the specific restricted hazardous wastes identified in this exemption reissuance, into Class I hazardous waste injection Wells WDW-163, WDW-164, and WDW-165 until December 31, 2028, unless EPA moves to terminate this exemption.
