The RCP has the potential to emit the following regulated air pollutants throughout the life of the mine: (a) total suspended particulate matter (TSP), (b) particulate matter (PM), (c) particulate matter less than 10 microns in aerodynamic diameter (PM10), (d) particulate matter less than 2.5 microns in aerodynamic diameter (PM2.5), (e) carbon monoxide (CO), (f) nitrogen oxides (NOx), (g) sulfur dioxide (SO2), (h) volatile organic compounds (VOCs), (i) sulfuric acid (H2SO4), (j) sulfate (SO4), (k) soot (elemental carbon), (l) hazardous air pollutants (HAPs), and (m) greenhouse gases (GHGs) including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
Emissions of potential pollutants are calculated using emission unit process rates, emission factors, and pollution control efficiencies (if applicable). The emission factors are determined using: (a) emission factors and methods from the latest version of the Compilation of Air Pollutant Emission Factors, Vol. I: Stationary, Point, and Area Sources (AP-42); (b) emission limitations and standards; (c) material balances; (d) EPA Tanks Program 4.0; (e) Fugitive Dust Emission Factors for the Mining Industry from the American Mining Congress (07/83); (f) emission rates from comparative equipment; (g) manufacturer’s information; and (h) EPA modeling programs.
