William J. Carter December 1, 1997 Re: 1997 Annual Reclamation Report (1)(t) Acres Previously Revegetated: Area Acres Year Lower Hubbard Creek 2.6 acres 1996 Bear Creek Fan Area 3.0 acres 1996 B~ Degas Hole 0.04 acres 1990 B-5 Degas Hole 0.25 acres 1990 B-7 Degas Hole 0.70 acres 1987 B-8 Degas Hole 0. ] 6 acres 1987 Total 6.75 acres (2xa) Weed Control: Thistles and Russian ICnapweed were controlled by spot spraying individual plants and patches of plants with a portable spray system applying Banvel and 2,4,D. Areas sprayed, as needed, included the disturbed areas from the Sanborn Creek Mine portals to the West Yard, Substation Number 3, and the Bear and Hubbard Creek Sites. (2xb) Rill and Gully Survey: As part of the routine monthly inspections, the reclaimed areas are evaluated for revegetation success and for the formation of rills and gullies deeper than nine inches. This past year was the first year for the Lower Hubbard Creek and Bear Creek Fan Area sites. Revegetation has started on both sites and there has not been significant formation of rills and gullies that required repair and seeding. The all-native plants used on the two sites may take as long as three seasons to become fully established. (2xc) Reclamation Map: Since the pemtit area for the Somerset and Sanborn Creek Mine is over 9,000 acres, and the total reclamation for the 92.3 acres of permitted disturbance is approximately 6.75 acres, any single base map would be meaningless, and any attempt to show disturbed areas, reclaimed azeas, what yeaz final seeding occurred, when baclcfilling and grading was completed, topsoil replacement depths, seed mix used, etc. would be confusing and difficult to present, at best. Instead, any review of this Annual Reclamation Report should be done with reference to the numerous individual area maps in the approved permit document already in the Division files. XB~w
