Application and Source Category Permit 7043-SC-R2 for Construction and Operation of Stationary Natural Gas-Fired Emergency Engines Subject to NSPS Subpart JJJJ
This source category permit and associated applications cover the construction and operation of certain stationary natural gas-fired emergency generator sets and other diesel-fired emergency engines subject to the federal “Standards of Performance for Stationary Spark Ignition Internal Combustion Engines” (NSPS Subpart JJJJ) and the air quality regulations of the District of Columbia. The first is an initial application form for any equipment that has not previously been covered by an air quality permit, including new installations. The second is a shorter renewal application form for any equipment that was previously approved for coverage under the previous versions of this source category permit (Permit No. 7043-SC-R1, issued September 27, 2019, or any earlier version) and has not had significant changes to the equipment or operations since the previous coverage approval.
