MACT Study

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. A seven-part series of technical bulletins Volatile Organic Compound Emissions from Wood Products Manufacturing Facilities (1999) documented the extensive sampling program conducted by NCASI to obtain information on emissions of hazardous air pollutants from wood products sources. Data generated in this study were used extensively by EPA to develop the emission limits in the PCWP MACT standards.
