MINE ID # OR PROSPECTING ID#: M-1973-021 PAGE: 4 <br />]INSPECTION DATE: 6-26-01 INSPECTOR'S INITIALS: ACS <br />quarry were inspected. The Operator spreads and compacts non- <br />marketable material onto the benches to form a wedge of fill resulting <br />in a smooth, steep hillside appearance, rather than a series of benches <br /><ind highwalls. This reclamation technique results in visuasl impacts <br />k>eing minimized and provides locations for disposal of crusher reject <br />rind other unsalable dirt. No indications of slumping in the fill <br />::lopes were observed during this inspection. Neither was any large <br />e:cale erosion of the fill observed. Revegetation and weed control on <br />t:he steep slopes will be challenging, but once vegetation is <br />Eastablished the bench backfilling method employed at the Morrison <br />()uarry should prove superior to other open pit slope r.=_clamation <br />practices. <br />C)ther observations: Reclamation along the west side (east facing) wall <br />of the north quarry was observed from a distance. Survival of trees in <br />this area, and the extent of cover of herbaceous pl,snts, are <br />indications that the quarry can be revegetated successfully. However, <br />most of this reclaimed area will be redisturbed under the current <br />c;uarry reclamation plan. Finally, it was noted that construction has <br />riot commenced on the engineered backfill slope proposed for the <br />s>outhwest corner of the north quarry. The approved mined land <br />zeclamation permit provides for inspections by the Division of Minerals <br />rind Geology during construction of underdrains for the engineered fill <br />:;lope. <br />Operations at the Morrison Quarry appear to be proceeding in accordance <br />with the terms of the approved permit. No problems were noted during <br />this inspection. <br />cc: Carl Mc•unt, DMG <br />Jim Stevens, DMG <br />Mr. Kent Pease <br />Haley and Aldrich <br />110 16th Street <br />Suite 900 <br />Denver, CO 80202- <br />5202 <br />I & E Contact Address <br />nfAME Mr. Mike Refer <br />OPERATOR Aagre4ate Industries - WCR.
