The U.S. Environmental Protection Agency’s Region 9 office has re-issued a final Prevention of Significant Deterioration (PSD) air permit to Sierra Pacific Industries-Anderson Division for a new cogeneration unit at its existing lumber manufacturing facility in Anderson, Calif.
The project consists of a new biomass-fired cogeneration unit, including a 468 MMBtu/hr stoker boiler, capable of generating 31 MW (gross), a 256 horsepower natural gas-fired emergency engine, and a three-cell cooling tower.
The SPI-Anderson facility is located at 19758 Riverside Avenue, Anderson, Calif. A 116.4 MMBtu/hr stoker boiler and associated equipment capable of producing 4 MW of gross electrical output are currently at this location.
This version of the PSD permit was issued on April 25. In February 2013, EPA Region 9 initially issued the final decision on this permit application. After an appeal by three individual citizens, in July 2013 the federal Environmental Appeals Board (EAB) remanded the permit to EPA Region 9 based on its conclusion that EPA Region 9 erred in failing to hold a mandatory public hearing. The EAB denied review of all other procedural and substantive challenges. A December 2013 public hearing was then held and the permit was re-issued.
