RECEB?~El~ 7. Weed Control MAY 2 7 2004 Dlvlaion of Minerals & GeoloDY iV~-1~1~5- OZ~I The Trust and its operators will take measures to ensure that the reclaimed land is free of weed infes- tations. Problem weeds will be monitored closely each spring for the first two yeazs after reclamation to determine if they are invading the area. In the event that noxious weeds are observed on site, a weed control plan will be developed and submitted to the DMG. Upon approval, the plan will be im- plemented as agreed. The Division will be consulted regazding any weed infestation area identified on site. It maybe necessary to control weeds by mowing after the first year; the feasibility of chemical weed control methods will be studied should it be necessary. The plan may not contemplate total weed removal on the property. Past experience shows that some initial weed cover (especially non- noxious variety) in the first year following retopsoiling is beneficial to the reclamation effort in non- imgated areas. Weeds tend to provide shade for new grasses, are a means of holding snow on the seedbed longer and protect it from wind and water erosion until the planted species have taken hold. 8. Reve~etation Success Criteria Since most of the area contains pre-law disturbance without topsoil salvage, it is suggested that revegetation on the reclaimed area should be deemed successful when the perennial vegetation in this area is self-sustaining and adequate to control erosion. The topsoil replacement procedures and the revegetation plan outlined earlier should be more than adequate to achieve this goal. The majority of the site has been reclaimed using standard procedures for restoring rangeland use although the true post-mining land use is commercial, open space and residential. The revegetated area will be monitored for success of reclamation until accepted by the Division. If revegetation failures occur prior to release, an analysis of the site will be made and the area will be revegetated again as necessary. Alma Placer 7/03 51
