Air, Energy and Mining

The Air, Energy and Mining Division permits and regulates environmentally-protective and productive operations in air, hard rock mining, opencut mining, and coal mining industries according to program statutory authority. The permitting and regulatory work includes extensive coordination with other programs to develop environmental review documents that comply with the Montana Environmental Policy Act, including environmental assessments and environmental impact statements. The division includes the State Energy Office, or Energy Bureau, which promotes and improves Montanans' access to energy efficiency and alternative energy sources while improving the state’s energy security by offering financing mechanisms, technical assistance, and education for public and private entities.

Waste Management & Remediation

The Waste Management and Remediation Division protects human health and the environment by preventing exposure to contaminants, working with Montana communities and businesses to implement effective material management and cleanup strategies, and overseeing compliance with state and federal laws and regulations. It oversees and conducts or supports remedial investigation and efficient, cost-effective cleanup activities at state and federal superfund sites; supervises voluntary cleanup activities; reclaims abandoned mine lands; implements corrective actions at sites; and administers regulatory asbestos, methamphetamine, and waste management programs.

Water Quality

The Water Quality Division protects public health and water quality in the state of Montana. This is accomplished through the financing and technical assistance provided for community water and wastewater systems; the development of water quality restoration plans; managing a State-wide monitoring network; subdivision review; monitoring compliance of public water systems; and water discharge permitting. The division achieves this through coordination with the public and regulated community by proposing rules, drafting policy, and developing water quality standards.

Director's Office

The Director's Office is responsible for agency-wide administration, management, planning, evaluation, and support. The programs within the Director's Office provide overall policy direction and support services to the agency in the areas of human resources, information management and technology, legal, enforcement, public affairs, fiscal, records management, safety, emergency management, and continuous process improvement.

The agency also provides administrative support to the Board of Environmental Review. In addition, although it is not attached to DEQ by law, the Petroleum Tank Release Compensation Board (PTRCB) is functionally supported by DEQ. The board provides procedures and resources for reimbursement of expenditures for cleanup of petroleum tank leaks. Finally, the 2017 Legislature established an advisory team, the Libby Asbestos Superfund Oversight Committee, that is also attached to DEQ for administrative purposes. Read more about these groups and more at the Affiliated Boards and Councils tab above.
