In 2012, EPA received responses from wool fiberglass companies which conducted furnace emissions testing for chromium compounds under a Clean Air Act section 114 letter. Industry data show that wool fiberglass area sources emit chromium from all furnace types. Emissions of chromium compounds from the wool fiberglass industry's area sources total over 50 pounds per year.

Additionally, one major source facility is expected to become an area source through changes to a process downstream and independent of the furnace; one furnace at that source has been measured as emitting over 500 pounds per year of chromium compounds. The agency plans to list and regulate area sources in the Wool Fiberglass source category for all processes that emit HAP. Area sources in this source category are expected to be regulated under this new subpart; major sources will continue to be subject to Part 63 NNN. This project has been subsumed into RIN 2060-AQ90, Mineral Wool/Wool Fiberglass RTR.
