Revised General Permit for Small Combustion Units
Pennsylvania DEP revised the General Plan Approval and/or General Operating Permit, commonly known as the GPA/GP-1, for Natural Gas and and No. 2 Oil Fired Small Combustion Units. The issuance of the new permit took effect upon publication of the January 28, 2023 version of the Pennsylvania Bulletin. The primary change of the GPA/GP-1 was to increase the size or rated capacity of the combustion units covered by the general permit from 50 million Btu per hour to 100 million Btu per hour. This new rated capacity of 100 million Btu/hr widens the size range of small combustion units allowed for GPA/GP-1 applications and helps modernize the emissions acceptable under the permitting process. Small business can find copies of the new GP-1 general permit applications, instructions, and additional information here.
