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