EPA Publishes Proposed Wood Coating MACT Amendments
The U.S. Environmental Protection Agency (EPA) published this week its proposed amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Surface Coating of Wood Building Products. This NESHAP, also known as the maximum achievable control technology (MACT) standard for wood coatings, applies to any facility engaged in the surface coating of wood building products. These proposed amendments are the result of the residual risk and technology review required under the Clean Air Act. EPA’s review determined that the risk of air toxics emissions under the current standards are acceptable from this source category and that no additional controls were necessary for facilities to protect public health.
Proposed amendments include: (i) adding an alternative compliance demonstration equation; (ii) changing provisions to startup, shutdown and malfunction periods; (iii) modifying the electronic reporting provision; and (iv) proposing a new test method to measure isocyanate compounds in certain surface coatings.
