District Rule 2520 identifies which major sources must obtain a Title V operating permit. Generally, these sources consist of:
District Rule 2530 allows major sources with actual emission levels below one half of the major source threshold to delay applying for a Title V permit until their actual emissions exceed that level.
On July 1, 2011 the Federal Environmental Protection Agency established major source thresholds for Greenhouse Gas (GHG) emissions and Title V permitting requirements for major sources of GHGs. Subsequently, on June 23, 2014 the U.S. Supreme Court ruled that GHG emissions cannot be considered in determining if a stationary source is a major stationary source for purposes of Title V permit requirements (and Prevention of Significant Deterioration permitting requirements). Therefore, as of June 23, 2014 facilities that are major sources solely due GHG emissions are no longer required to obtain or maintain a Title V permit.
