Montana 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 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 proposed rule because we believe this action is not controversial. Unless we get written comments opposing this authorization during the comment period, the decision to authorize Montana's changes to their hazardous waste program will take effect as provided below. If we receive comments that oppose this action, we will publish a document in the Federal Register withdrawing this rule before it takes effect. A separate document in the proposed rules section of this Federal Register will serve as the proposal to authorize the State's changes.
