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:

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.

EMAP assists small businesses with:

  •  Understanding which equipment at your facility may be subject to (or exempt from) regulatory requirements
  • Calculating emissions from all sources
  • Preparing and submitting a Request for Determination and any required plan approvals or permit applications
  • Finding alternative materials or processes which may reduce your regulatory burden
