Underground Injection Control Program; Hazardous Waste Injection Restrictions; Petition for Exemption Reissuance-Class I Hazardous Waste Injection; U. S. Ecology Texas (USET) Robstown, Texas

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 USET for two Class I hazardous waste injection wells located at their Robstown, Texas facility. The company has adequately demonstrated to the satisfaction of the 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 USET of the specific restricted hazardous wastes identified in this exemption reissuance, into Class I hazardous waste injection wells WDW-278 and WDW-279 until December 31, 2030, unless the EPA moves to terminate this exemption or other petition condition limitations are reached. Additional conditions included in this final decision may be reviewed by contacting the EPA Region 6 Ground Water/UIC Section. A public notice was issued March 29, 2018, and the public comment period closed on May 15, 2018, and 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.
