<br />• <br />Page 2 <br />Mr. John Ward <br />March 3, 1981 <br />Materials and buildings remaining at the Tunnel Portal from <br />tunnel construction were salvaged and removed during late <br />summer. Approximately 2 acres of the former 10-acre storage <br />area will continue to be used for storage. The remaininc 8 <br />acres was scarified, and grass seed and fertilizer were <br />broadcast. This area may be required at some point in the future <br />to serve as a track welding area. <br />Continued tailing deposition now affects about 505 acres. <br />That figure and the other disturbance inside the tailing basin <br />(bypass canal, roads, pipelines and topsoil removal) is less <br />than the 575 acres of anticipated and bonded affected lac.d <br />designated for the tailing in the timetable through for <br />December, 1981. A technical revision of the permit was granted <br />in July, 1980, relative to the Tailing Deposition Area. <br />Approximately 50 additional acres associated with <br />clearing/construction for road, powerline right-of-way, a.nd <br />storage yard were required. Acres traded for the 50-acre: <br />disturbance came from the Topsoil Stockpile/Roads Area ir. Ute <br />Park. We petitioned for the return of these 50 acres to the <br />Topsoil Stockpile Area in the amendment dated January 27, 1981. <br />15,000 cubic yards of topsoil were spread on the lower benches <br />and slopes of the main tailing dam during August-October, 1980. <br />Grass seed and fertilizer were concurrently broadcast on the <br />topsoil. <br />A landfill was closed in the Powerline/Refuse Area, covered <br />with topsoil, and revegetated. Follow-up spot seeding/fe:rtiliz- <br />ing of this area will be done in 1981. <br />A Notice of Intent to Conduct Prospecting Operation:. with <br />respect to the location of a dam/reservoir on Lost Creek was <br />filed/received in August, 1980. Prospecting operations ceased <br />in October, 1980. Drill roads/sites were seeded and fertilized <br />according to the Reclamation Plan, and follow-up revegeta.tion <br />will occur in 1981. This area was also included in the January <br />27, 1981 amendment application. <br />Other 1980 activities included: <br />1. Mine Site. Pilot boring for #5 shaft (ventilation) <br />began. An addition to the electrical office building <br />was constructed. An addition to the sewage treatment <br />plant building was begun and should be finished in the <br />first quarter of 1981. Construction of a mine «ir <br />intake heating system at #3 shaft utilizing heat: from <br />minewater and waste oil recycling/burning was begun in <br />1980 and should be operational in the first halm of <br />1981. Contrary to our expectations, subsidence com- <br />menced on September 11, 1980. <br />
