TABLES <br />ENERGY FUELS RESOURCES CORPORATION- WHIRLWIND MINE <br />MATERIAL HANDLING EMISSIONS -CRITERIA POLLUTANTS <br />Emission Source: MATERIAL HANDLING -ORE AND WASTE ROCK LOADING AND UNLOADING <br />Pollutants: TSP and PMro <br />Emission Factor From: AP-42, Section 11.24 <br />"Metallic Minerals Processing" <br />Emission Factor Rating: A <br />Explanation: Moist to wet ore and waste rock will be hauled to the surface in mine trucks and buggies: Ore and wasta <br />rock hauled out [he Whirlwind Portal will be dumped directly on the ore pad and waste dump, <br />respectively. A small portion of the mined ore and waste rock will be brought to the surface through the <br />Packrat Portal and dumped into bins. It will [hen be transferred [o [he ore pad and waste dump with <br />highway haulers. Ore will [hen be loaded on highway haul tracks with pups for transportation to a mill. <br />Equations: Annual PMr° emissions (tons/yr) = E * P * OD * (ton/2000 lb) <br />Short-term PMro emissions (Ibslhr) = E * P / OH <br />P (from Packrat Portal) = Pra * P (Total) <br />P (Waste Rock) = WR:Ore * P (Ore) <br />Where: E =Emission factor (Ib/ton) <br />P =Daily production rate (tpd) <br />OD = Operating days per year (day/yr) <br />OH =Working hours per day (hrs/day) <br />P°n = Percent of ore exiting the Packrat Portal <br />WR;Ore =Average waste rock to ore ratio <br />Data: E (PMro) = 0.004 Ib/ton [Emission factors for high-moisture ore, material handling and <br />transfer of all minerals except bauxite (AP-42, Section 11.24- <br />E(PM)= O.OI Ib/ton 2)1 <br />P (Ore) = 200 tpd [Maximum daily ore production m[e] <br />Pea- 10% <br />WR:Ore= 2.75:1 <br />OD= 250 day/yr <br />OH= l6 hr/day <br /> <br />Material Handling P <br />(tpd) PMro Emissions <br />(Ibslhr) (tons/yr) PM Emissions <br />(Ibslhr) (tons/yr) <br />High-Moisture Ore <br />-Unload into bins at Packmt Portal 20 O.OI 0.01 0.01 0.03 <br />- Load onto haul truck at Packrat Portal bins 20 O.OI 0.01 0.01 0.03 <br />-Unload onto ore pile from both portals 200 0.05 O.IO 0.13 0.25 <br />-Load onto highway hauler 200 0.05 0.10 0.13 0.25 <br />High-Moisture Waste Rock <br />-Unload into bins a[ Packm[ Portal 55 0.01 0.03 0.03 0.07 <br />- Load onto haul track at Packmt Portal bins 55 0.01 0.03 0.03 0.07 <br />-Unload onto waste dump from both portals 550 0.14 0.25 0.34 0.69 <br />Total Emissions 0.28 0.55 0.69 1.38 <br />1 Total suspended paniculates is assumed to be equivalent to particulate matter (PM), as referenced in AP-42, Section 11.24. <br />
