Owens Corning owns and operates a wool fiberglass manufacturing facility located at 400 Case Avenue, Newark, Ohio (the Facility). Emission sources at the Facility include several wool fiberglass furnaces, forming processes, curing ovens, and cooling and trimming operations for processing fiberglass.
On June 12, 2012, EPA issued Permit to Install (PTI) No. P0108954 to Owens Corning to remove federally-enforceable limitations for volatile organic compounds (VOC), which applied to, among other units, emission unit P066 (F-6 Oven) and P128 (F-6 Cooling Section). On September 26, 2013, Ohio Environmental Protection Agency (OEPA) issued PTI No. P0113568 to Owens Corning to increase the allowable VOC emission limits for the curing and cooling processes when employing non-phenolic binder. The PTI applies to, among other units, emission unit P055 (C-4 curing oven).
On September 27, 2017, EPA issued a Notice of Violation (NOV) to Owens Corning for violating emission limits established in accordance with the Ohio State Implementation Plan, and PTIs issued on June 12, 2012, and on September 26, 2013, respectively. Specifically, January 2013 stack test demonstrated that the F-6 Curing Oven P066 and F-6 Cooling Section P128 emitted VOC emissions in excess of 0.50 and 2.40 pound per ton of binder solids applied, respectively, when employing non-phenolic binder as required by the June 12, 2012 PTI. A November 5, 2013 stack test demonstrated that the C-4 Curing Oven P055 emitted VOC emis
