Air Permitting
National Summary
Air emissions permits are divided into two distinct categories: construction permits and operating permits. The applicability of various permitting programs within each category is dependent on the type and quantity of the pollutants emitted, the attainment status of the area where the source is located, and the date the source was constructed or modified. The quantity of emissions from a source will determine whether the source can be classified as a major source or if changes at the source can be classified as a major modification. Major sources must comply with federal construction and operating permit programs, most of which are administered at the state or local level.
