CDPH&E - 4 - February 9, 1996 • lb/vMT for TSP and PM10, respectively. These result in uncontrolled emissions of 1.246 tons/year TSP and 0.408 tons/year PM10. With a control efficiency of 508 for graveled roads, estimated controlled emissions are 0.623 tons/year TSP and 0.204 tons/year PM10. Uncontrolled emissions estimates for hauling topsoil during site preparation are 447.57 tons/year TSP and 146.72 tonslyear PM10. Estimates of controlled emissions are 223.79 tons/year TSP and 73.36 tons/year PM10. Emissions from the overburden stockpile were estimated from emission factors found in Table 8.19.1-1, 'Uncontrolled Particulate Emission Factors for Open Dust Sources at Sand and Gravel Processing Plants.' The uncontrolled emission factors for active storage piles with a normal mix of active and inactive days are 10.4 lb/acre/day and 5.0 lb/acre/day for TSP and PM10, respectively. Uncontrolled emissions estimates are 1.215 tons/year TSP and 0.584 tons/year PM10. For a control efficiency of 258 for moist material, the controlled emissions for the overburden stockpile are 0.911 tons/year TSP and 0.438 tons/year PM10. Overburden removed in the preparation of the site will be used as fill and revegetated within the first year. Uncontrolled emissions are estimated to be 6.219 tons/year TSP and 3.021 tons/year PM10. Estimated controlled emission rates, with a control efficiency of 758 for rapid revegetation, are 1.555 tons/year TSP and 0.755 tons/year PM10. The same emission factors of 10.4 and 5.0 lb/acre/day from Table 8.19.1-1 were used to calculate emissions from the temporary gob pile and the open coal stockpile. The resulting uncontrolled emissions are 0.517 and 0.249 tons/year TSP and PM10, respectively for the gob pile, and 6.355 tons/year TSP and 3.055 tons/year PM10 for the open coal stockpile. Uncontrolled emission factors for the drilling and blasting processes were found from page 3, with the area equal to 507,055 square feet, depth equal to 30 feet, and moisture content equal to 7.98 (from Table 8.24-3). Emission factors of 1.3 lb/hole TSP and 0.365 lblhole PM10 for drilling yield uncontrolled emission rates of 13.65 tons/year TSP and 3.828 tons/year PM10. The emission factors for blasting are 1522 lb/blast TSP and 240 lb/blast PM10. Estimated uncontrolled emission rates for blasting are 91.32 tons/year TSP and 14.4 tons/year PM10. Estimated emissions factors for the conveyors and transfers were calculated from Equation 1, §13.2.4 of AP-42, as 0.0029 lb/ton TSP and 0.001371 lb/ton PM10. Total uncontrolled emissions for all transfer points were 42.46 tons/year TSP and 20.08 tons/year PM10. With a control efficiency of 858 for the fully enclosed transfer points, estimated controlled emissions are 11.36 • tons/year TSP and 5.373 tons/year PM10.
