Fugitive Emission Factor Tests
Air Control Techniques, P.C. have conducted a number of studies to develop new, more accurate emission factors for fugitive dust sources including crushers, screens, conveyor transfer points, and unpaved roads. These tests have involved innovative techniques to complete capture of the fugitive emissions and accurate quantification of the PM10, PM4, PM2.5, and PM1 fugitive emissions. Our emission factor tests conducted for the National Stone, Sand, and Gravel Association has saved the Crushed Stone Industry more than 400 million dollars.
