Air permit guidance documents
- APG-576 - Diesel Engine-Generator Set Procedure for Writing New and Modified Permits
- APG-578 - Sudden and Reasonably Unforeseeable Events in the Context of Planned Electric Outages
The revised guidance document, APG-576 - Diesel Engine-Generator Set Procedure for Writing New and Modified Permits, became effective April 9, 2026. This revision to DEQ Guidance Memo APG-576 (last updated December 2012), creates new sections of the existing document that address presumptive Best Available Control Technology (BACT) and performance testing requirements specific to emergency and non-emergency gen-sets located at data center stationary sources.
Based upon recent DEQ permitting and compliance experience as described more fully in the revised guidance, the presumptive BACT for both emergency and non-emergency gen-sets located as data centers is now based on the use of a selective catalytic reduction (SCR) system or equivalent for nitrogen oxides control, a diesel oxidation catalyst system or equivalent for carbon monoxide control and a diesel particulate filter (DPF) or equivalent for particulate matter control. Collectively, this suite of air pollution control systems is sometimes known as Tier 4-equivalent.
In order to allow the regulated community sufficient notice of the updated BACT requirements, the revised document specifies the updated BACT requirements for emergency and non-emergency diesel gen-sets located at data centers will be applicable to air permit applications received on or after July 1, 2026. The presumptive BACT requirements for diesel gen-sets located at non-data center stationary sources remain unchanged.
