The State of Montana Department of Environmental Quality has applied to the Environmental Protection Agency (EPA) for final authorization of the changes to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA). The EPA has determined that these changes satisfy all requirements needed to qualify for final authorization, and is authorizing the State's changes through this direct final action. The EPA uses the regulations entitled "Approved State Hazardous Waste Management Programs" to provide notice of the authorization status of State programs and to incorporate by reference those provisions of State statutes and regulations that will be subject to the EPA's inspection and enforcement. This rule also codifies in the regulations the approval of Montana's hazardous waste management program and incorporates by reference the authorized provisions of the State's regulations.
