What are to be the maximum gradients of reclaimed slopes that are backfilled or reduced by cutting? Please describe the methods to be used for closure or safeguarding used in the final reclamation of each portal Exhibit E - Mining Plan Map and Reclamation Map (Rule 6.3.5): The maps all lack a few items, which may be simple to add, since the maps are all generated digitally. Please ensure all revised maps include their appropriate map titles, proper exhibit, north arrow, scale, labeled permit boundary, and sufficient topographic information (especially on the Reclamation Map). All maps must be signed by a person qualified for preparing the map, and the date prepared. Please also refer to Hard Rock/Metals Rule 6.2.1(2). On the Mining Map, please depict the explosives magazines, if explosives are stored onsite. On the Mining Map, please show the locations of the new piezometers. The Reclamation Map should have final topography shown, and any present features that are to be removed during reclamation should not be depicted. The Reclamation Map should distinguish between areas to be revegetated and those areas that will not be revegetated. The maps that show the expanded permitted area boundary should also show and label the existing 3.5-acre permit boundary. Numerous maps that depict the 3 Level road and portal and the proposed new boundary (such as Figures A.6 and B.1, for example) did not show the correct location of the 3 Level pad. It should be moved about 600 feet farther to the southeast, so that it is depicted to the northeast of the 6 Level, not directly to the north. (Note: If the acreage calculation in this amendment was based on an incorrect boundary delineation at the 3 Level, a new acreage calculation will be required, in addition to the new maps.) Note: The present permitted acreage is based on two previous amendments to this permit, the history of which merits a brief summary. The original acreage was 0.6 acres, which was limited to the 6 Level portal and small pad area. Amendment AM-1 added 1.0 acres, consisting of the 3 Level portal/pad area. Amendment AM-2 expanded the 6 Level pad/dump by 1.5 acres, and added 0.4 acres of upper access road (10'x1500'). [AM-2 also originally included another 0.6 acres for a lower access road, to be built by extending an existing BLM road. That road was prohibited by BLM, and that area was withdrawn from AM-2, leaving the net total of 3.5 acres.] The important fact here is that the existing permitted acreage already includes a ten-foot wide road corridor from the "saddle" down to the 6 Level pad. As noted above, revised maps are required showing the corrected 3 Level pad location, but it may result in an acreage increase. Such increase may be offset somewhat by accounting for the existing permitted portion of the 6 Level access road. This amendment submittal was preceded by receipt of a copy of the most recent iteration of the stormwater management plan (SWMP) that was sent to CDPHE/WQCD. The 6 Level access road was shown with a series of drainage control structures, including riprapped outfall locations on the slope below the road. Given the limitations of depicting these structures at that scale, it is not clear if they are actually inside the proposed amended road corridor boundary. Please ensure that the new boundary includes these, and all other, SWMP structures. Exhibit T (Rule 6.4.20) - Environmental Protection Plan (EPP): Please address the questions of ore storage (locations, maximum volumes, storage timeframes, onsite processing, storage structures or handling), especially ensuring that any existing or future structures (which are defined as environmental protection facilities, or EPFs) have been certified by a Colorado-licensed PE.
