• • • <br />PAGE <br />rapped emergency spillway is free ..f vegetation and is being <br />maintained. <br />The monitoring wells in Mann llraw are n~:t rapped per MLF,U <br />approval bey=ause of the gaseous nature ~~f, the hydrologic regimes that <br />are being checked. Several of the wells need tr_. be worked r_~n because <br />s~~il around the ~=asings is starting to sin4_:. There are n~~ wells that <br />have soil dropped nut to the aquifer being monitored but the <br />situation should be ~=~~rrected before this happens. <br />The par shall tlume and statt gauge on the downstream end cif Mann <br />Draw nn the permit area is being maintained. Uurinq the previous OSM <br />oversigh+. inspection, it was noted in the MSEIF.' report that the flume <br />sh~~uld be lowered to mare effe~_tively monitor the ephermeral flows, <br />that was implemented. <br />Fond "b" was dry. The primary spillway, a drop inlet with a trash <br />rac4:, is starting to cant an an angle fr~~m the horizontal because it <br />is not anch~~red. the prc,blem is caused by freezing and thawing cycles <br />during the winter as ice pulls the strLrcture away from the <br />horizontal, This pond is not bac4;ed up by another dawn stream, it <br />instead, is the lower of two in a serie~•. The situation should be <br />watched if it becomes worse. corrective measures should be <br />implemented. The other pond in the series, had a small amount e,f <br />water in it. The spillways c.n it were functic,nal, no problems noted <br />. The drainage area of disturbed ar_res being ~=ontrolled by these twe <br />ponds has been modified by the company's bacl:tilling activities. Fart <br />of the overland. flows will probably go bacL: towards the pit now <br />because spoil is being pulled r_~ff cat the top of the pile frir <br />backfillinq. <br />The rer_laim planted areas were chec4;ed. The vegetative stands <br />are uniform, it appears as though they hays a lot of sage starting en <br />most of the area. Urainaq_e on the reclaimed areas is positive. <br />Fond "H" was dry. The drawdc~wn valve can the drop inlet principal <br />spillway was clr_,sed. All spillways were tunctional and being <br />maintained. <br />Topsoil piles nn the mine are revered with temporary cover and <br />mar I;ed. <br />The drainage flr_~w direction r~tf the yard area near the mine -~tfir_e <br />is questi~~nable. The grade levels in that area are nearly zero, <br />there also is no evidence of accumulation er flows r_~ff of the <br />perimeter and the berms in the area are being. Eut there appears t., <br />be a low area near the office well that should be watched t^ <br />determine! the dire=tion of flow and if there is any amount of <br />runoff that leaves the permit boundary untreated. If this is <br />nrrurrinq_ a violation should be issued. <br />their loadout north of i_owdrey, ~_nlr~radn was checked. The area <br />has not been used sinr_e the last QSM oversight inspe~=ti cm. There is <br />nq real stared along the railroad siding other than a r_ouple ~~f cubic <br />yards of waste that is bladed up on the east end of the narrow <br />relr~ading strip. The area is secured and marled with the appropriate <br />mine IU signs. The topsail salvaged from the area is r_overed with <br />temporary vegetation and is marked. Urainage r_ontrol for the area is <br />adequate and is being maintained. there is no sediment pond because <br />the area is sr. small but the perimeter is bounded by a series of <br />berms and ditches that adequately prevent runr~ff from leaving the <br />area. <br />
