and access roads would also be accomplished. Work at the fans <br /> includes minor grading for drainage control purposes and <br /> revegetation. I envision this project to mainly entail <br /> modification of the hydrologic control system currently in place on <br /> the road network. Ideally, the work would progress by filling in <br /> the drainage ditches in place on the inside of the roads. Drainage <br /> culverts would either be permanently sealed (depth greater than 3 <br /> feet) or removed (depth less than 3 feet) . Drainage structures, <br /> such as rolling dips, low water crossings, water bars or cut out <br /> trenches would be constructed in order that surface flows are not <br /> diverted out of their natural watersheds. Road surfaces and less <br /> steep slopes (slopes gentler than 3H:1V) would be revegetated. <br /> Rock Tunnel Entry This project would consist of diverting the <br /> mine flow to North Fork of Dutch Creek, demolishing and disposing <br /> of concrete materials, backfilling the highwall and revegetating <br /> the area. I have observed the entries to discharge slightly more <br /> than 2 cubic feet per second (reports from Resources indicate flows <br /> to 8.8 cfs) . The water is fairly innocuous, having little in the <br /> way of detectable metals (including iron) and sulfates, and a Ph of <br /> 8. 5 to 9. 1 . During 1995 runoff, it was apparent that water built <br /> up within the entries to a height of about six feet behind the <br /> block walls. Resources has recently expressed concern regarding <br /> the integrity of their block walls, and has suggested leaving the <br /> entries open in case of future failure of the walls. This seems to <br /> be a health and safety problem, as well as an environmental issue. <br /> I am thinking of installing 4 feet diameter concrete sewer pipe <br /> through the backfill to transport the flow from within the entries. <br /> The large diameter will be more than sufficient to handle the flow, <br /> and will also be large enough to permit access to within the <br /> entries in order to monitor the block walls. The flow will need to <br /> be directed to North Fork of Dutch Creek via a channel to be <br /> constructed as part of the project. Backfill will be obtained from <br /> the eastern portion of the bench and from the channel excavation. <br /> The entire area will be ripped, fertilized and seeded. <br /> Rock Tunnel Dumb This project will call for removal of large <br /> durable sandstone reported to be located here. A minor amount of <br /> grading will be accomplished to enhance runoff from the upper <br /> (south western) portion of the dump. A drainage channel will need <br /> to be constructed along the southern flank of the pile to convey <br /> runoff. The dump generally consists of course rock materials. <br /> Very little topsoil is available for use. I am proposing that <br /> cover material be obtained by excavating the outside portions of <br /> Road B (from the Rock Tunnel entry to the junction of the 4 Mine <br /> road) . This would serve to partially reclaim Road B while <br /> providing cover for the Dump. The minor amount of available <br /> topsoil would be distributed on the dump and the site revegetated. <br /> Revegetation It is my guess that the most viable and economic <br /> method of revegetating the mine bench outslopes to some manner of <br /> self sustaining community will be to construct artificial shelves <br /> 3 <br />
