Major Source (Title V) Permits
The District issues "major source" or "Title V" federal operating permits to various stationary sources of air pollution that meet the requirements. These permits are referred to as Title V permits in reference to that specific section of the federal Clean Air Act (CAA) enacted by the U.S. Congress in 1990.
The Title V Program requires local and state air quality agencies to issue comprehensive operating permits to facilities that emit significant amounts of air pollutants. For all implementing agencies in the country, there are standard requirements for permit programs and permit content. Title V operating permits differ from other District issues operating permits in that they explicitly include the reqirements of all regulations that apply to operations at Title V facilities.
Major Sources

Major sources are categorized by having actual or potential emissions that meet or exceed the major source threshold for that location. The major source threshold for any "air pollutant" is 100 tons/year and for "hazardous air pollutants" (HAP) it is 10 tons/year for a single HAP or 25 tons/year for any combination of HAP.
The District has several facilities that have Title V Operating Permits as follows:
