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.
MONTANA'S AIR PROGRAM
Montana's SIP was officially submitted to EPA in March 1972 and is frequently amended to comply with the 1990 CAA amendments. The SIP focuses on permitting, nonattainment areas, HAPs, NSPS, and numerous other air-related requirements.
