On September 23, 2023, PADEP published in the Pennsylvania Bulletin notice that the agency finalized its General Plan Approval and/or General Operating Permit for Coal-Mine Methane Enclosed Flares (GP-21). See 53 Pa. Bull. 6005 (Sept. 23, 2023). New or modified coal-mine methane enclosed flares in Pennsylvania are now subject to GP-21. Coal-mine methane enclosed flares with actual emission rates less than the following are exempted from GP-21’s permitting requirements:
- 4 tons per year (tpy) of carbon monoxide (CO) from a single enclosed flare or 20 tpy of CO from multiple enclosed flares;
- 1 tpy of nitrogen oxides (NOx) from a single enclosed flare or 5 tpy of NOx from multiple enclosed flares;
- 1.6 tpy of the oxides of sulfur (Sox) from a single enclosed flare or tpy 8 of the SOx from multiple enclosed flares;
- 0.6 tpy of particulate matter with a diameter of 10 microns or less (PM10) from a single enclosed flare or 3 tpy of PM10 from multiple enclosed flares;
- 1 tpy of volatile organic compounds (VOCs) from a single enclosed flare or 5 tpy of VOCs from multiple enclosed flares; and
- 0.5 tpy of a single hazardous air pollutant (HAP) from a single enclosed flare or 1 tpy of multiple HAPs from multiple enclosed flares. The HAPs may not contain Polychlorinated Biphenyls (PCBs), Chromium (Cr), Mercury (Hg), Lead (Pb), Polycyclic Organic Matter (POM), Dioxins, or Furans.
