Colorado; Final Approval of State Underground Storage Tank Program Revisions and Codification

Pursuant to the Resource Conservation and Recovery Act (RCRA or Act), the Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the State of Colorado's Underground Storage Tank (UST) Program submitted by the State. The EPA has determined that these revisions satisfy all requirements needed for program approval. This action also codifies the EPA's approval of Colorado's State program and incorporates by reference those provisions of the State's regulations that we have determined meet the requirements for approval. The State's federally authorized and codified UST program, as revised pursuant to this action, will remain subject to the EPA's inspection and enforcement authorities under Sections 9005 and 9006 of RCRA Subtitle I and other applicable statutory and regulatory provisions.
