Although the topsoil will be removed and unloaded by front-end
loaders and trucks, an estimate of the emissions for topsoil
removal and unloading was made using the emission factors from
the table, 'Emission Factors Applicable to All Mining
Operations,' on page three of the Tistinic memorandum, for
topsoil handling by scraper and topsoil removal by scraper. The
TSP emission factors for topsoil removal and topsoil unloading
are 0.058 and 0.04 lb/ton, respectively. PM10 emission factors
of 0.0285 lb/ton for removal and 0.0195 lb/ton for unloading were
determined using the method of Appendix A of the Tistinic
memorandum. Estimated uncontrolled emissions for topsoil
removal from the permanent gob pile and topsoil removal during
the site preparation are 5.590 tons/year TSP and 2.747 tons/year
PM10. Using a control efficiency of 508 for moist material, the
controlled emissions estimates for TSP and PM10 are 2.795
tons/year and 1.373 tons/year, respectively, for topsoil removal.
Uncontrolled emissions for topsoil unloading are 3.855 tons/year
• TSP and 1.879 tons/year PM10. A control efficiency factor of 50$
for unloading moist material results in estimated controlled
emissions for topsoil unloading of 1.928 tons/year TSP and 0.940
tons/year PM10.
Uncontrolled emissions for the topsoil stockpiles were also
estimated using the emission factors found in the table on page
three. The TSP emission factor is 0.38 lb/ton and the PM10
emission factor is 0.1876 lb/ton. The resulting uncontrolled
emissions for the stockpile of topsoil removed from the permanent
gob pile location are 0.1406 tons/year TSP and 0.0694 tons/year
PM10. Using a control efficiency factor of 25$ for moist
material, the controlled emissions estimates are 0.106 tone/year
TSP and 0.052 tonslyear PM10. The uncontrolled emissions
estimates for the stockpile of topsoil removed in site
preparation are 1.244 tons/year TSP and 0.614 tons/year PM10.
Estimates of controlled emissions are 0.311 tons/year TSP and
0.154 tons/year PM10, using a control efficiency of 758 for rapid
revegetation.
Fugitive emissions caused by hauling topsoil from the permanent
gob pile to a topsoil stockpile were estimated using emission
factors from Table 8.24-2, 'Emission Factor Equations for
Uncontrolled Open Dust Sources at Western Surface Coal Mines,'
for haul trucks. The number of wheels, w, is 10, and the road
• surface silt loading is 40.8 g/m', the geometric mean found in
Table 8.24-3, 'Typical Values for Correction Factors Applicable
to the Predictive Emission Factor Equations.' The uncontrolled
emission factors are estimated to be 35.335 lb/VMT and 11.583
