Mr. R. Burgess <br />8/23!02 <br />Page 4 of 5 <br />4. Revegetation <br />In your comment letter, you provided Homestake with new guidance regarding the recommended <br />seed mix and application rate for the project area. Based on this guidance, the seed mix and <br />application rates selected for the project are provided in Table 2. <br />Table 2 Seed mixture for final reclamation at the Bulldog Mine <br />Common name Scientific name Pounds PLS per acre <br />Slender Wheatgrass Agropyron trachycaulum 9.0 <br />Western Wheatgrass Agropyron smithii 13.0 <br />Rocky Mountain Penstemon o) Penstemon strictus 2.0 <br />Blue Flax t~) Adenolinum lewisii 1.0 <br />Arizona Fescue Redondo ti) Festuca arizonica 1.0 <br />Total 22.0 to 26.0 <br />(1) 7fiese species are oprierial <br />Seed will be placed on the disturbed area using a broadcast spreader. If considered necessary, the <br />topsoil will be scarified prior to seeding. After seeding, fertilizer will be spread on the reseeded <br />area to promote growth. Fertilizer type will be based on general recommendations made in the <br />lab soils analyses attached. <br />5. Maintenance <br />Homestake currently has an active stormwater permit with the CDHPE for the Bulldog mine. <br />The new bypass facilities will fall under this permit, which requires routine inspection and <br />maintenance. Inspection and maintenance will continue for the duration of the stormwater permit <br />and the current Operating Plan filed with the Forest Service. <br />6. Sprinkler System Removal <br />Homestake will remove the sprinkler system materials prior to addition of a sail cover on the <br />9360 dump. <br />Adit Closure <br />Contingent on approval by the DMG, Homestake will close the old abandoned adit that is located <br />just to the north of the 9700 dump. Closure will consist of constructing an access to the adit, <br />removing any debris and filling in the opening of the adit with native material. As part of this <br />closure, Homestake will also remove the minor amount of old waste rock that was generated from <br />the adit and move it to the 9700 dump. Details, or changes, regarding this work will of course <br />depend on DMG recommendations / concurcence. <br />This work will result in some additional disturbance from that shown on the plans in TR-l 1. The <br />disturbed area consists primarily of talus, which may be used as a source of riprap for the <br />overflow channels. Any new disturbance will be regraded. Since the area currently consists of <br />talus, placement of soil and re-seeding is inappropriate. <br />
