A significant portion of NCASI activities in Air Quality, along the focus areas described above, involve studies related to plywood and composite wood products (PCWP) manufacturing. Activities in the wood products program seek to fill the critical data needs of this segment and develop technical information that informs EPA and enables Member companies to optimally operate their facilities.
Wood Products
Current NCASI studies in the wood products program are focused on positioning the industry for the upcoming MACT residual risk and technology review (RTR) and reconsideration of MACT for remanded miscellaneous process units. NCASI studies are evaluating the variability of VOC/HAP emissions from miscellaneous process units like sanders, saws, screens,…

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…

The Wood Products program is credited with developing, compiling, and updating an extensive database of air emissions from sources at wood products facilities, reflecting extensive studies around wood products plants in the 1990s to develop data on Hazardous Air Pollutant (HAP) and volatile organic compounds (VOC) emissions. The first version…

The use of F-factors in combustion calculations is an area of NCASI expertise. These tools are important to estimate boiler heat inputs, track/validate fuel firing scenarios, estimate air flows and carry-out other combustion-related assessments. NCASI has also developed calculation tools for use in converting emissions to varying production / throughput…

Recent NCASI technical activity in this area seeks to evaluate the use of OTM-026, in conjunction with modified Method 25A to develop better estimates of speciated VOC emissions from wood products sources. This activity commenced in the late 1990s when the forest products industry initiated a multi-year research study on…

Learn MoreNCASI maintains electronic databases of air emissions test results for both pulp and paper mill sources and for wood products plant sources. The database for pulp and paper sources was expanded this year to include criteria air pollutants (SO2, NOx, CO, particulate matter, and total VOCs). The wood products database also includes both 'air toxics’ and criteria air pollutants.
