Maryland has applied to the United States Environmental Protection Agency (EPA) for final authorization of revisions to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA). EPA has determined that these revisions satisfy all requirements needed to qualify for final authorization and is authorizing Maryland's revisions through this direct final rule. In the "Proposed Rules" section of today's Federal Register, EPA is also publishing a separate document that serves as the proposal to authorize these revisions. EPA believes this action is not controversial and does not expect comments that oppose it. Unless EPA receives written comments that oppose this authorization during the comment period, the decision to authorize Maryland's revisions to its hazardous waste program will take effect. If EPA receives comments that oppose this action, EPA will publish a document in the Federal Register withdrawing today's direct final rule before it takes effect and the separate document in today's "Proposed Rules" section of this Federal Register will serve as the proposal to authorize the revisions.
