CF&I STEEL COkPORATION CANON DOLOMITE QUARRY File No. 77-376 ANNUAL REPORT to the MLRD September 1987 - September 1988 (1) CF&I (Fountain Sand & Gravel) operated the Canon the report period, however, no additional acres active mining operations are restricted to areas past mining. No additional acres, previously disturbed during the remaining life of the quarry. Dolomite Quarry during were disturbed. All already disturbed by undisturbed, will be (2) Lower Fines Disposal Area lil was graded to final contours and seeded during the week of Sept. 21, 1987. This area covers approximately 6 acres. The pre-law quarry area above the office was also seeded at this time. Erosion control and maintenance is continuing as required. (3) Approximately 4 acres along the north and south ends of the quarry floor are currently being graded to final contours. These areas have fines as a topsoil substitute. Seeding should begin this fall. (4) The species planted include Crested & Thickspike wheatgrass, Sideoats Grama, Russian Wildrye, Indian Ricegrass, Fourwing Saltbush Palmer Penstemon and Yellow Sweetclover as per the approved seed mixture. Planting ocurred during the last weeks of September, 1987. ficrc~( ~ a~~r~ (6) Approximately 200 lbs 0-46-0 fe ilizer was lied to the reseeded areas. An additi ons of compost was applied which will _act_ as a fertilizer and soil onaitioner. (6) The revegetation of the roadcuts which were seeded in 1986 and appeared marginal the first year have improved markedly after the compost was applied last year. Though much of the cover species are legumes and annuals, same grasses are becoming established. The areas seeded this last year are on the average not as dense as the roadcuts, however they appear to be doing considerably better than the roadcuts in their first year. Poor moisture conditions during the winter and early spring appear too have lowered the germination rate. Late summer rains have helped invading species, some of which are grases. The second season should show improvement. (7) Mining will continue at a very reduced rate for some years to come, however all future mining will be restricted to those areas previously disturbed by mining. No undisturbed areas will be affected by future mining. (8) This report is current as of September 1, 1988.
