Comparison: State vs. Federal

Rules. Montana's air program is shaped by its SIP, which sets forth basic strategies for implementation, maintenance, and enforcement of the National Ambient Air Quality Standards (NAAQS). As mandated by the federal Clean Air Act (CAA), each state must adopt and submit a SIP to the U.S. Environmental Protection Agency (EPA) for approval.

Administration and enforcement. DEQ's Air Resources Management Bureau is responsible for administering and enforcing Montana's air pollution rules.
