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 New Mexico's Underground Storage Tank (UST) program submitted by the State. EPA has determined that these revisions satisfy all requirements needed for program approval. This action also codifies EPA's approval of New Mexico's State program and incorporates by reference those provisions of the State regulations that we have determined meet the requirements for approval. The provisions will be subject to EPA's inspection and enforcement authorities under Subtitle I of RCRA sections 9005 and 9006 and other applicable statutory and regulatory provisions.
