Due to EPA's implementation of more stringent standards for particulate matter with an effective diameter less than 2.5 microns, the cotton ginners' associations across the cotton belt, including the National, Texas, Southern, Southeastern, and California Associations, agreed that there is an urgent need to collect gin emission data. The primary issues surrounding particulate matter regulations for cotton ginning industry are: 1) limited or lack of PM2.5 data; 2) potential over-prediction of current dispersion models; and 3) effects of sampler errors. In response to the Gin Associations' requests, a cotton gin particulate matter emissions sampling project, "Characterization of Cotton Gin Particulate Matter Emissions", was planned by USDA-ARS researchers, the Gin Associations, and State and Federal Regulators. During 2009, the first full year of the sampling campaign, three gins were extensively sampled in Texas and California, over 5800 samples and data from four gins were processed and analyzed [ABSTRACT FROM AUTHOR] |
