Surface Coating of Wood Building Products: National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
Rule Summary
The final standards establish emission limitations, operating limits, and work practice requirements for all major sources that apply a surface coating to a wood building product to reduce certain organics listed as hazardous air pollutants (HAP) in section 112 of the Clean Air Act (CAA). These standards implement section 112(d) of the CAA by requiring all major sources to meet the HAP emission standards reflecting the application of the maximum achievable control technology (MACT).
Wood building products surface coating operations emit several HAP, including xylenes, toluene, ethyl benzene, ethylene glycol monobutyl ether (EGBE), other glycol ethers, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK), methanol, styrene, and formaldehyde.
