. EDNA MINE - 1994 EROSION INVENTORY REPORT <br />OVERVIEW <br />Section 4.3 of Permit No. C-80-001 requires an annual erosion <br />inventory of the Edna Mine's permanently reclaimed lands that <br />remain under bond. The permit requires that an inventory report be <br />submitted to the CDMG on or before April 30th of each year. The <br />first erosion inventory report of this process was done in the <br />spring of 1993 since approval of the permit section containing this <br />language was not granted until after snowfall in 1992. <br />Several areas not previously detailed were added to the inventory. <br />Block 3 of the Moffat Area reclaimed area is a live handled topsoil <br />area that will receive a reclamation seed mix application in the <br />spring of 1994. This block is bordered by Block 2 of the Moffat <br />Area reclaim on the east and by the lower Moffat Area haul road to <br />the west. This area was topsoiled in 1993. Block 4 of the Moffat <br />Area reclaim lies immediately north of Block 1 and is bordered to <br />the east by the upper Moffat haul road and on the west by the <br />middle Moffat haul road. This block is also live handled roto- <br />cleared topsoil, but will not have additional seeding as part of <br />the ongoing study area dealing with live handle topsoil vegetation <br />success. Block 5 of the Moffat Area reclaimed lands is a live <br />handled topsoil area that will have a reclamation seed mix applied <br />in the spring of 1994. This block lies directly north of Block 2, <br />and is bordered on the east and west by the middle Moffat haul road <br />and the lower Moffat haul road respectively. Block 6 of the Moffat <br />Area reclaimed area is a live handled topsoil area that will also <br />have a reclamation seed mixture applied in the spring of 1994. <br />This block is the first reclaim area below the lower Moffat haul <br />road. It is bordered on the south by the toe of the Moffat out of <br />pit spoils, on the east by the lower Moffat haul road and on the <br />west by the edge of the mining disturbance. <br />Areas permanently reclaimed that are required to be inventoried <br />under the plan include the reclaimed areas, to date, on the Moffat <br />Area, an approximately 10 acre strip in the South of Shop Area and <br />areas permanently reclaimed on West Ridge. The West Ridge areas <br />are currently exempt from inventory requirements pending <br />construction of runoff control structures required by the West <br />Ridge Hydrologic Reconstruction Plan. Three sections in the West <br />Ridge Area were voluntarily evaluated, and are included in this <br />report for future evaluation of the effectiveness of the West Ridge <br />Hydrologic Plan's success. Results of the inventory are described <br />below. The inventoried areas are referenced to Exhibit 1 of the <br />1992 Erosion Inventory Report for the West Ridge and South of Shop <br />areas and Exhibit 4 ("Permanent Revegetation") of the 1993 Annual <br />Reclamation Report for the Moffat Area. <br />4/18/94 DLB <br />
