Governing Law and Regulations
Wyoming Department of Environmental Quality (DEQ) Air Quality Division
Comparison: State vs. Federal
Rules. Wyoming's air permitting program requires a permit for the construction, modification, and/or use of any stationary source that emits, or may emit, pollutants into the air. In addition, major sources are required to comply with the applicable provisions of PSD. See the state section NEW SOURCE REVIEW for additional information on major source construction permitting requirements.
Wyoming does not have a separate operating permit program for nonmajor sources. Operating permits will be issued after such sources demonstrate compliance with applicable state and federal regulations, and with the terms and conditions of the construction permit. However, major sources are subject to the provisions of the Title V operating permit program. See the state section TITLE V for additional information on major source operating permitting requirements. Administration and enforcement. DEQ's Air Quality Division administers and enforces the air permitting rules in Wyoming.
