~~ AREA SUBJECT TO EFFLUENT LIMITATION GUIDELINES As before noted, there is no runoff from the 3 level dump. Where vehicle tires have compacted the soil, road surfaces may temporarily hold water in potholes. The 6 level dump area is partially composed of clayey rock derived from the mine. Where it is permanently wetted, such as by the 2 to 3 gpm flow of mine water coming out the portal, the dump material will permit a surface flow. However, even that has sunk back into the ground before it departs the site. On the three or four occasions when the writer has been on the site at the time of a thunderstorm, no runoff from them has been noted. Where Deadman Gulch and its tributary (see site map) cross the dump there was flow for about two months in the Spring of 1995. These drainages have intermittent flow but, prior to the Spring of 1995 when heavy, wet snows contributed mightily to the snowpack and rapid Spring runoff, no flow had been noted in the lower part of this drainage in the last 15 to 20 years. Home construction had taken place in the outflow area downslope with apparent dis- regard for potential damage by water from the drainage, probably because of the lack of observed flow. The Alferd Packer Massacre Site is also in this outflow area and appears to have been rela- tively unaffected in the time that it has been there, many tens of years. SITE MAP Two site maps are included with this SWMP, one for the 3 Level Dump Area and another for the 6 Level Dump Area. There is_alsn an index map showing the locations of the dumps relative to one an- other. As before stated, no runoff from the 3 Level dump has ever been noted. No equipment is permanently stationed outside on this level except for a generator and compressor which are portable but are used when mining operations are underway. Front end loaders are also employed but are not ordinarily left on site. The gener- ator and compressor are serviced where they are located while the front end loader would be serviced wherever it is convenient. Any of the surface area of the dump might be used for materials (waste or ore) storage. The entire dump is, literally, waste rock stor- age. There is no flow of water, either permanent or intermittent, across this site. None of this area is surfaced with asphalt or any other impervious material. No surface runoff during storm events has been noted on the 6 Level dump or site area either. However, there is a 2 to 3 gpm flow from the 6 Level portal which runs across the surface of the dump and down the face of the dump where it sinks into the dump and disappears before departing the site. This has been observed by a number of people including inspectors from the Division of Minerals and Geology. Intermittent drainage down Deadman Gulch and from the side drainage shown on the map merges below the berm below the diesel fuel tank (which is not used) and flows down across the dump just north of the generator and compressor loca- tions to where it flows off the dump and back into Deadman Gulch drainage. This is an inherited situation from prior operators (2.)
