Major Source (Title V) Permits
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.
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.
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.
