The paper presents measurements for particulate matter (PM) emission particle size profiles from scraper loading, unloading, and transport operations. The exposure profiling technique was used to measure emissions. This technique for source testing of open PM sources is based on the isokinetic profiling concept that is used in conventional (stack) testing. The passage of airborne pollutant immediately downwind of the source is measured directly by means of simultaneous multipoint sampling over the cross section of the open dust source plume. Within field measurement capabilities, several types of PM collection devices were utilized to validate the test procedure and enhance the quality assurance goals of the test program. During the field testing, source activity data were gathered to combine with the emission measurements to develop emission source strengths. The source activity data gathered included: vehicle type, speed, number of axles and tires, rate of vehicle loading/unloading and start/stop time, silt and moisture content of soils, and data regarding water use for dust control and/or materials compaction.
