Mr. Rich Atkinson - 7 - May 12, 1987 9. The permit renewal document proposes a post-mine vegetation diversity standard which will contain at least four principle species of the same lifeform and seasonal variety as identified in the pre-mine diversity calculations (Page 4.15-21 renewal document). The original permit application committed to six principle species (Page 4.15-14). The renewal document presents a justification for deleting two of these species. One of the deleted species is an annual forb (weed?), Gallium sp. The other is a perrenial forb Lupinus caudatus.whic~~r certain conditions may be toxic to livestoccf-,, an w ich may be present in relatively high numbers due to overgrazing. The Division proposes to approve this revision to the revegetation standards. Maps Map 1 - The ownership change near the warehouse from Leander to Colowyo should be explained. Map 2 - The ownership change near the loadout from Gossard to Colowyo should be explained. This map should also be listed as revised in 1987. Map 4 - This map should be revised to show the various test plot and seeding trial locations (i. e. shrub only seeding areas). Map 10 - The operator should check the monitoring sites on Good Spring Creek to verify that they are properly located on the map. Maps 11 & 12 - On Map 11 there are several circled letters which appear to relate to drainages. However, on Map 12 the drainages do not contain these letters. These two maps should be consistent. If the letters are used to reference areas for runoff calculations, they should be on both maps and identified in the map legends. Map 18 - The pre-mine topography represented in Map 18 (January 1981) is not acceptable, as it depicts the mining / activity. The correct map to use for pre-mining '~71 topography is the one submitted on May 25, 1982, and marked "revised September 1981, April 1982." Other Maps - Several maps show mining activity which occurs outside the "area to be mined boundary "in Section 11. These maps include maps 4, 6 and 29. The operator should explain the reason for these activities, including a description of legal rights of entry and operation in this area.
