RFDs & Permits
Did You Know...?
Air permitting regulations apply to all businesses – regardless of size!
Adding or expanding a source (equipment or process) with air emissions may require a permit. Examples include:
- Boilers and Furnaces
- Paint booths
- Surface coating operations
- Portable crushers
- Internal Combusion Engines
- Emergency generators
- Woodworking operations
- Degreasing operations
- Shot blast/sandblasting units
- Asphalt production
- Compressors for natural gas
DEP has exempted some types of air pollutant sources from permit requirements. These exemptions are included on DEP's Air Quality Exemption List.
By submitting a “Request for Determination” (RFD) to DEP you can receive written verification that your source is exempt.
