Rules.The Wyoming Department of Environmental Quality’s (DEQ) Title V operating permit program mirrors the federal requirements.

See the national section TITLE V for more information on the federal requirements.
Administration and enforcement. DEQ’s Air Quality Division administers and enforces the Title V program in Wyoming.
NON-TITLE V OPERATING PERMITS
In Wyoming, submission of an application for a construction permit also serves as an application for a minor source operating permit. Upon completion of construction, a permit to operate will be issued if the facility demonstrates, to DEQ's satisfaction, that it is in compliance with the Wyoming air quality regulations and that the facility has been constructed or modified in accordance with the terms and conditions of the construction permit. For information on construction permits and minor source operating permits, see the state sections AIR EMISSIONS PERMITS.
Synthetic Minor Permits
Sources with potential emissions above the major source threshold may request a permit with a federally enforceable emissions cap that limits emissions to below major source thresholds, thereby avoiding Title V applicability. Such sources must monitor and record sufficient data to demonstrate that emissions are below major source thresholds and comply with all other applicable requirements.
