~~ir. J.R. Owen -3- December 7. 1984 Exhibit C - Map 1. None of the maps given of the exact permit areas are adequate at this time. A sketch map such as you have provided is acceptable, and the fact that a scale is given in each case is helpful. However, none of the maps give an exact outline of the acreage you propose to permit. I agree that showing the existing old pit (in those cases where there is one) is a good idea. However, you must then draw in the boundaries that correspond to the acreage you wish to actually permit outside of that old pit. Given the scale on each map, a permit area must be shown that corresponds to the acreage figure requested. 2. Although it is fairly obvious that north is to the top of most of your maps, you should provide a directional arrow on your maps. 3. Where appropriate, you should show planned locations of various items referenced in your mining plan. These could include topsoil and product stockpiles, processing areas (if any), etc. Exhibit E - Reclamtion Plan 1. Reclaimed slopes should be specified for all pits. Any slopes to be successfully revegetated should be no steeper than 3H:1V. If slopes are proposed to be steeper than this, their existence should be justified, and if they are to be revegetated, extra measures (e.g., netting, contouring, etc.) should be outlined to aid in establishment of vegetation on such steep slopes. 2. In the cases where an ephemeral drainage is to be mined, our hydrologists suggest that side banks (parallel to flows) should be left at no steeper than 3:1 and that the ends of the excavation (perpendicular to flows) be left at no steeper than 10:1. This should assure the stability of the reclaimed area over time and minimize the possibility of off-site erosion. 3. In all cases where topsoil is to be replaced for use in reclamation, the proposed replacement depth should be given. Individual Operations Earl Forristal Pit - File No. M-84-180 Exhibit B 1. Please elaborate on the placement of the dam across the creek bed. How does it interact with the mining operation and with the flow of the drainage? Is the dam removed and replaced each year? If not, how is the flow of the drainage preserved since the dam blocks it? Are culverts provided through the dam? Such a dam could radically affect the flow and configuration of the creek bed. It should be either justified or removed.
