Regulatory Agency

Maine Department of Environmental Protection (DEP)

Bureau of Air Quality

Comparison: State vs. Federal
  • Rules. Maine is authorized by the U.S. Environmental Protection Agency (EPA) to administer its own air emissions permit program. DEP requires all new or modified sources of air pollution to obtain an air emissions license, with major sources required to obtain a Title V operating permit referred to in Maine as a Part 70 air emissions license. The Maine Title V program follows the federal provisions, including provisions establishing greenhouse gas permitting thresholds, and received full approval from the U.S. Environmental Protection Agency (EPA).
  • Administration and enforcement. DEP's Bureau of Air Quality administers and enforces the state's air emissions permitting rules.

Any source that has the potential to emit regulated pollutants below the established thresholds must obtain a minor source air emissions license from DEP before beginning actual construction, modification, or operation, unless the source is specifically exempted for licensing requirements. See the state section AIR EMISSIONS PERMITS for more information.
