Maryland has applied to EPA for final authorization of changes to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA). EPA has determined that these changes satisfy all requirements needed to qualify for final authorization and is authorizing Maryland's changes through this immediate final action. EPA is publishing this rule to authorize the changes without a prior proposal because we believe this action is not controversial and do not expect comments that oppose it. Unless we receive written comments which oppose this authorization during the comment period, the decision to authorize Maryland's changes to its hazardous waste program will take effect. If we receive comments that oppose this action, or portions thereof, we will publish a document in the Federal Register withdrawing the relevant portions of this rule before they take effect and a separate document in the proposed rules section of this Federal Register will serve as a proposal to authorize changes to Maryland's program that were the subject of adverse comments.
