Energy Facility Site Evaluation Council Draft Air Operating Permit and Technical Support Document

In accordance with Revised Code of Washington (RCW) 80.50 and Washington Administrative Code (WAC) 463-78-010 and WAC 463-78-005, NOTICE is hereby given that the Washington State Energy Facility Site Evaluation Council (EFSEC) has made a tentative determination to issue for public comment an Air Operating Permit (AOP) and associated Technical Support Document (TSD) Permit No. EFSEC/XXXX-XX. The Grays Harbor Energy Center is located at 401 Keys Rd, Elma WA 98541. Permit compliance will be governed by applicable provisions of RCW 80.50, WAC 463-78, and WAC 463-70.

The facility is referred to as the Grays Harbor Energy Center (GHEC). GHEC is capable of generating up to 650 megawatts (MW) of electricity from a combined-cycle power plant comprised of two combustion turbines, each equipped with a duct burner and heat recovery steam generator and a single steam turbine and bank of cooling towers shared in common. GHEC also operates an auxiliary boiler, a diesel emergency generator and an emergency fire water pump. Commercial operation of GHEC began on April 25, 2008.

The GHEC has the potential to emit several regulated air pollutants above their major source thresholds. In addition, GHEC is an affected source under Title IV (Acid Deposition Control) of the federal Clean Air Act, which independently triggers the requirement to obtain a Title V AOP. AOPs are required pursuant to Title V of the Federal Clean Air Act and are designed to help ensure compliance with applicable air quality regulations and standards. Because GHEC is capable of generating up to 650 MW of electricity and is a “major source” as defined in WAC 173-401-200(19), GHEC is required to operate under an AOP issued by EFSEC.
