Technical Abstract: This manuscript is part of a series of manuscripts that characterize cotton gin emissions from the standpoint of stack sampling. The impetus behind this project was the urgent need to collect additional cotton gin emissions data to address current regulatory issues. A key component of this study was focused on EPA total particulate emission factors. EPA AP-42 emission factors are generally assigned a rating that is used to assess the quality of the data being referenced. The ratings can range from A (Excellent) to E (Poor). EPA current total particulate emission factor quality ratings for cotton gins are extremely low. Cotton gins received these low ratings because the data was collected almost exclusively from a single geographical region. The objective for this study was to collect additional total particulate emission factor data, based on the EPA approved stack sampling methodology, for mote cleaner systems from cotton gins located in regions across the cotton belt. The project plan included sampling seven cotton gins across the cotton belt. Key factors for selecting specific cotton gins included: 1) facility location (geographically diverse), 2) industry representative production capacity, 3) typical processing systems and 4) equipped with properly designed and maintained 1D3D cyclones. Two of the seven gins had mote cleaner systems. The exhaust from one of the mote cleaner systems was combined with the module feeder dust system. In terms of capacity, the two gins were typical of the industry; averaging 32.7 and 47.0 bales/hr during testing for the stand alone mote cleaner system and mote cleaner and module feeder dust system, respectively. The average measured total particulate emission factor for the stand alone mote cleaner system was 0.105 kg/bale (0.232 lb/bale). The average measured total particulate emission factors for the mote cleaner system combined with the module feeder dust system was 0.109 kg/bale (0.239 lb/bale).
