Air Permit Types & Requirements
New Source Review (NSR) Permits
What does a NSR permit do?
Protects air quality when sources like the following are newly built or modified:
- Factories
- Industrial boilers
- Power plants
Assures the following take place:
- New/modified industrial sources are as clean as possible
- Advances in pollution control grow simultaneously with industrial expansion
Who is required to obtain a permit?
When sources of air emissions at a facility are built or modified, there are potentially 3 types of NSR permitting requirements (a facility may have to meet one or more of these requirements)
- Prevention of Significant Deterioration (PSD) Permits
- Required for new major sources or major sources making a major modification in areas that meet the National Ambient Air Quality Standards (NAAQS)
- Nonattainment NSR (NNSR) Permits
- Required for new major sources or major sources making a major modification in areas that don't meet the NAAQS
- Minor Source Permits
- For pollutants from stationary sources that don't require PSD or NNSR permits.
Title V Operating Permits
What does a Title V Operating Permit do?
Legally enforceable documents designed to improve compliance by clarifying what facilities must do to control air pollution.
Who is required to obtain a permit?
Any major source that has actual or potential emissions at or above the major source threshold for any air pollutant
- Any source with a PSD permit or NNSR permit
- Affected sources under the Acid Rain rules
- Solid Waste Incineration Units under Section 129 of the Clean Air Act
- Certain non-major sources subject to NSPS/NESHAP/MACT/GACT requirements
