NESHAP for Aerospace Manufacturing and Rework Facilities (40 CFR Part 63, Subpart GG) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Aerospace Manufacturing and Rework Facilities (40 CFR Part 63, Subpart GG) were proposed on June 6, 1994; promulgated on September 1, 1995 and amended on both December 7, 2015 and August 3, 2016. These regulations apply to existing and new aerospace manufacturing and rework facilities where the total hazardous air pollutants (HAP) emitted are greater than or equal to 10 tons per year of any combination of HAP, or where the total HAP emitted are greater than or equal to 25 tons per year of any combination of HAP. New facilities include those that commenced construction or reconstruction after the date of proposal. Operations covered include: cleaning, primer and top coat application, depainting, chemical milling maskant application, handling and storage of waste, and specialty coating operations. This information is being collected to assure compliance with 40 CFR Part 63, Subpart GG. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
