The State of Maryland (State) 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 the State's changes through this immediate final action. EPA is publishing this rule to authorize the changes without a prior proposal because we view this as a routine program change and do not expect comments that oppose it. Unless we get 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 as provided below. If we get comments that oppose this action, or portions thereof, we will publish a document in the Federal Register withdrawing this rule, or portions thereof, before it takes effect, and a separate document in the proposed rules section of this Federal Register will serve as a proposal to authorize the changes.
