The <br />alts Is proposed a9 a 35 acre 112 operatloa whlc6 would crush stockpiles of gravel [or NNre use In procesalug hot mix an site. The permit ladlcatea <br />Nat the Forest SeMce la permitted to crush sad use gravel hom the pit far use on Porest Serrice proJecta. <br />The operatlon was permitted In 1988 as a special 111 operatlou where gravel was to 6e crushed sad stockpiled for future use. The operatlon has <br />apparently beau cntshing gravel lately which la beyond Ne latent of Ne special 111 permlL The Olvislon of Highways submitted Ne 112 permit <br />appDcatlos as a cortectlve actlon to remedy Ne problem wIN aperatlng beyond Ne IDtended scope at a 111 peruilL <br />No problems were touad wIN Ne undisturbed area at Ne proposed l12 permit area and Neretore Ne 112 appDcatlon will be approved wIN Ne <br />coadltloa Nat Ne USFS Special Use Peraill Is granted for Ne 112. The second coadltloa la Nat Ne 112 apptlcatloD be revised to address some <br />erosional problems Nat were anted on Ne 111 pit site during this Inapectlon. <br />This 112 permit appllcatlos Is approved as of May 2, 1996 and 111 Permit No. MSS-062 Is terminated as of Nat date. <br />Erosion rills and guWea were anted IaltlaUag at Ne upper cud of Ne pit and progressively growlag as Ney moved Nrough Ne taclDtles area and <br />down Ne road m Ne lower taclDtles area. The tacltltles pad and Ne berme used as sediment control are constructed of rock chips wIN very law <br />cohesion. The berms did trap some sediment but all except Ne uppermost berm were blows ouL Tke rock chip material appears to be highly erodible <br />and should sot be used In Ne coasWCtlos of sediment control atrvcmres. Water from above Ne pll ells was allowed to flow onto and Nrough Ne <br />pit site which compounded Ne problem. The operator wltl seed to revise Ne sediment coutrol plan to divert upgradleat water around Ne alts to <br />prevent Ne erosloa caused by Nis addltlonal volume at water. Addltlanally, Ne operator will ueed to address Ne erosloulsedlmeataUou problem <br />occurtlog In Ne dlsmrbed area and ensure Nat the revised plan will handle Ne antlclpated ronott and sediment load hom Ne proposed 112 operatloa. <br />Permll boundary markers are not In place and a1i1 need la be Installed for Ne 112 permit area as soon as possible. <br />Na permanent manmade etrucmrea other Nan Nase IdentlDed la Ne 112 appDcaUan were anted wlNlu 200 feet of Ne permit area. <br />The site la curteuUy Idle except for occasional hauDng of gravel hom Ne on-site stockpiles. The disturbed areas of Ne 111 alts have been seeded, <br />wIN Ne approved seed mix, to help control erosion while Ne pit alts Idle. <br />[ & E Contact Address <br />NAME ]oho Ackerman <br />OPERATOR Colo.
