SGL Composites, Moses Lake
Air Operating Permit
Dec. 30, 2024, 12 a.m. - Feb. 3, 2025, 11:59 p.m. PT
We propose to approve SGL Carbon Fibers' air quality air operating permit (AOP).
SGL Carbon Fibers America applied for an air operating permit for their composites facility located at 8781 Randolph Road NE, in Moses Lake. SGL Composites produces polycarbonate fiber. Production starts by loading boxes of polyacrylonitrile filaments onto the process lines. These filaments then pass through a series of ovens that gradually get hotter, followed by furnaces that burn off impurities from the material. The carbonization process tightens the fibers. After that, the finished product is wound onto spools, then packaged and shipped.
