SUPPLEMENTARY INFORMATION:

As required by 40 CFR part 148, Rubicon LLC adequately demonstrated to the EPA by the petition issuance 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 the Geismar Louisiana Facility, of the specific restricted hazardous wastes identified in this exemption issuance, into Class I hazardous waste injection Well WDW–6 until December 31, 2040, unless EPA terminates this exemption under provisions of 40 CFR 148.24.
