Wood Products

EPA issued the Plywood and Composite Wood Panel Maximum Achievable Control Technology (PCWP MACT, 40 CFR Part 63, Subpart DDDD) emission standards in July 2004. These standards established hazardous air pollutant (HAP) emission limits for certain panel plants and engineered lumber operations that are major sources. EPA is currently reconsidering MACT for remanded miscellaneous process units in this Subpart while also conducting the residual risk and technology review (RTR). NCASI carried out an extensive sampling program to obtain information that formed the basis of the original MACT standard and is currently providing regulatory support for the ongoing RTR process.
