<br />Total suspended particulates (TSP) frum [he pru pu=ed e>:pausion should not <br />exceed present mar.imum levels because there will b~• no increas•_ in coal <br />production over the 3.9 million tons bein; Wined c~irrently. <br />Under Che PSD permit, Energ}• Fuels is required [o use a variety of measures to <br />control fugitive dust. These measures are now bcir.g used and include waterinb <br />haulroads; appl}•ing a chemical stabilizer to hnulrnads; removir.^ any coal, <br />rock, soil, or other dust-forming debris from has roads; restricting haul <br />trucks to speeds of 35 miles oer hour; seeding ar.c! c,ulching new haulroad <br />embankment slopes; equipping all crushing, scre,ning, and conve.;inr operation<_ <br />at Energy tipple 2 and coal transfer points nn the convey acce wish •.~n ter <br />spraying systems; installing bat houses on prim;i::: and secondary crushers of <br />the sample house a[ Energy tipple 2; and using a stacl:ino tubs at the <br />100,000-ton crushed coal stnc4;pile. if coal dust becomes a problem from the <br />storage piles (opacity cannot e::ceed 20`L), Enemy Fuels p'.ans to use a <br />high-pressure water pump and nozzels to spray the coal. <br />Energy Fuels will reclaim disturbed land contenporaneously with r.:ining as <br />another method to control fugitive dust (topsoil .:ill oe revegetated to <br />minimize erosion). In addition, an air-qualit:• monitoring network designed to <br />meet CPA and OSM standards will be set up to monitor TSP and the rebv monitor <br />the effectiveness o: the fugitive-dust control plan. Currently, the ne_wor;; <br />consists of 5 high-volume TSP samplers around thc• permit ar_a. OS ht is <br />requiring Energy Fuels to install a sixth sampler or to move an er.isting <br />sampler to an upwind position south-southwest or the Ec'r.man Park area prior to <br />mining. <br />Impacts to the environment will continue to occur even ~'-•ith pollution <br />controls. Fugitive-dust emissions will increase slightly because of lon~_er <br />haul roads `_rom Ec4:man Yark to the tipple n[ mine "'. Visibiii[y in the Eckman <br />Parh area will also be impaired. In addition, there will he an unquantifiable <br />effect on vegetation and wildlife. These impacts are shore-term (life of <br />mine) and if Energy Fuels follows present futii[iv_•-dust control plans, no <br />further impacts to air quality should occur. <br />Hydrolog}' <br />Ground water <br />The proposed mining operation in [he Eckmar.
