The American Coatings Association las learned that the U.S. Environmental Protection Agency, EPA, is currently reviewing the Aerospace Manufacturing Maximum Achievable Control Technology, a.ka. MACT, standards under the National Emission Standards for Hazardous Air Pollutants rule for aerospace manufacturing. As part of its review, EPA visited 10 facilities and required the aerospace industry to submit detailed information on the coatings used at aerospace manufacturing operations. It appears that the agency is seeking to change the measurement of HAP limits from the current lbs./gal., to volume coating solids.
The American Coatings Association and industry are engaging on this front in order to ensure that the new limits are technically feasible and cost effective. In addition, based on a recent court ruling, EPA believes that aerospace operations excluded from the original rule -- including specialty coatings -- must now be regulated.
