What's Next for the Aerospace NESHAP?

摘要

Since 1998, many aerospace manufacturing and rework facilities have been operating and maintaining records in accordance with 40 CFR Part 63 Subpart GG, commonly referred to as the Aerospace National Emission Standard for Hazardous Air Pollutants, or NESHAP. Under the Clean Air Act (CAA), the U.S. EPA is required to continually revise the longstanding regulation. The industry is still at least a few months away from getting a glimpse at the next proposed revision-and at least three years away from having to actually implement the requirements in the forthcoming regulation. However, some reasonable projections of what the revised aerospace NESHAP rule will look like can be made based on the CAA, recent NESHAPs issued by EPA for other similar industries/source categories, information posted on the EPA website and discussions with aerospace industry trade groups and individual aerospace companies.
