Public comments are being accepted until March 29, 2022 on proposed revisions to Pennsylvania DEP Bureau of Air Quality's General Plan Approval and/or General Operating Permit for Gas and No. 2 Oil Fired Small Combustion Units. This general permit is commonly referred to as the GP-1 air quality permit.

A notice for the proposed revision was published in the Pennsylvania Bulletin on January 29, 2022.

Significant proposed changes or modifications to the GP-1 include the following:

  • General Permit Format - mostly structural changes for consistency issues.
  • General Permit Fees - most significant is the increase of the application fee to $1,600 from the existing fee of $375.
  • Applicability/Scope - the maximum rated heat input capacity has been increased from 50 million Btu's to 100 million Btu's.
  • Best Available Technology (BAT) - specific emission criteria has been specified under this proposed revision.
  • Source Testing - emissions testing for CO and NOx to be done within 180 days of initial startup or re-authorization to use the GP-1.
  • Work Practice Standards - annual tune-ups to be required along with measurement of NOx and CO every 3 years.
  • Applicable Laws - language has been included to reference federal requirements under 40 CFR Part 63, Subpart DDDDD and Subpart JJJJJ.
  • Annual Reporting and Compliance Certification - annual reports for emissions and compliance certification will be needed.

Pennsylvania small businesses may submit written comments to Pennsylvania DEP on these proposed revisions through Tuesday, March 29th, 2022. Comments are to be submitted through DEP's eComment Portal
