:.~ <br /> <br />the stream bank and would be environmentally unacceptable. Therefore, <br />this sediment pond will not be required to meet the slope criteria <br />of retention dam construction. Straw bales are staked along the creek <br />below the bridge. These provide adequate sediment control for the <br />small disturbed areas. These areas should be topsoiled and planted <br />as soon as possible. <br />No water monitoring is presently occurring on the site. No Notices <br />of Violation were written because no mine water or runoff from <br />disturbed areas is being discharged. Upon completion of the drain- <br />age system and pond, water must be monitored in compliance with the <br />NPDES permit during periods of discharge. These records should be <br />available at the mine. <br />717.20 Topsoil Handling and Revegetation <br />The operator was fined by the State of Colorado for failure to remove <br />topsoil during the construction of the portal bench. The Colorado <br />Mined Land Reclamation Board has ordered the operator to replace the <br />topsoil lost during this construction. This topsoil will be purchased <br />and stockpiled on a turnout on the mine access road. Topsoil from <br />construction of drainage system features will also be added to this <br />stockpile. Dave Asher raised the question of using soils which collect <br />in the large settling pond for reclamation. It is suggested that <br />laboratory soil analysis and field tests be conducted with this <br />material to determine its adequacy for revegetation. <br />No revegetation has begun. The major structures that need revegetation <br />are the fill slopes below the roads and portals. Small areas in the <br />valley bottom next to the mine road where straw dikes have been placed <br />should be topsoiled and reseeded as described in 717.20(b). <br />d' <br />GARY L.
