Answer:
The Environmental Protection Agency has listed ‘‘Paint Stripping,’’ ‘‘Plastic Parts and Products (Surface Coating),’’ and ‘‘Autobody Refinishing Paint Shops’’ as area sources of hazardous air pollutants (HAP) that contribute to the risk to public health in urban areas under the Integrated Urban Air Toxics Strategy. This final rule includes emissions standards that reflect the generally available control technology or management practices in each of these area source categories.
For the purpose of this standard, paint stripping operations are those that perform paint stripping using methylene chloride (MeCl) for the removal of dried paint (including but not limited to paint, enamel, varnish, shellac, and lacquer) from wood, metal, plastic, and other substrates at area sources. Miscellaneous surface coating operations are those that involve the spray application of coatings that contain compounds of chromium (Cr), lead (Pb), manganese (Mn), nickel (Ni), or cadmium (Cd).
Implementation of the final standards will achieve a reduction of 6,900 tons per year (tpy) of HAP from surface coating operations. In addition to the HAP, it is estimated a reduction of 2,900 tpy of PM emissions, and a reduction of approximately 20,900 tpy of VOC emissions.
