Henderson Mini Permit No. 77-342 a February 12, 1 page 3 Grass seed and fertilizer were broadcast concurrently with the topsoil spreading while seed bed receptivity was high. Slopes seeded in early summer were showing grass seedlings by the end of the growing season. Shrub seeds were also planted in moist locations of East Branch Reservoir shores and the seepwater entrapment canal, areas 6 and 20 respectively. Tree density was increased with the addition of 1,200 more plants in selected locations of Area 20 and the topsoil berm (Area 21). Other areas with sparse vegetation were spot reseeded with grass seed. Salvage materials and construction buildings at Ryan's camp (Area 12) and near the north topsoil stockpile (Area 21) were removed in the fall. Totally, about one acre was scarified, seeded and fertilized. Phase I construction of Lost Creek Reservoir and ,pipe- line right-of-way (Area 23) commenced in late spring with timber clearing. About eight acres of construction disturbance were final-graded in 1981 and were seeded ,snd fertilized as construction was completed. Follow-up revegetation will occur in 1982. Additional construction is scheduled for the 1983 and the 1985 seasons. Continued tailing deposition (Area 9) now affects about 567 acres. That figure and the acreage of other disturbances inside the tailing basin (bypass canal, roads, pipelin~as, and topsoil removal) total less than the 705 acres of antis:ipated affected land designated for the tailing basin in the time- table for December 1981. Timber was also cleared from 15 acres of the topsoil stockpile area (Area 21) on the northwest edge of the trailing basin in preparation for further stockpiling. The timber was made available to employees for firewood. A road was cut through Area 18 to provide vehicule~r access between No. 1 and No. 3 tailing dams. Surety An update of reclamation costs was completed in May, 1981, following approval in April, 1981, of the amended plan. Receipt of the update to the bond was confirmed by the Mined Land Reclamation Division on July 17, 1981. Therefore, no update of costs is included in this annual report. The biennial computation of costs for purposes of surety as specified by the Board will be included in next year's annual report.
