RECLAMATION PLAN EXHIBIT E (CONT) <br /> The revegetated areas will be monitored closely each spring <br /> for the first two years to determine if noxious weeds are <br /> invading the area . Colorado Crushing, Inc, will implement a weed <br /> monitoring and control plan for this mine and have included a <br /> copy in the Appendix for your review. Weed control will be <br /> initiated if the problem becomes serious or if an excessive weed <br /> cover is still present at the end of the second year. In no way <br /> should this be taken to mean that we will try to eradicate all <br /> the weeds from the site . Some weeds are beneficial to the game <br /> species in the area, they provide important protection from the <br /> elements during winter and nesting sites during the spring. <br /> Total eradication of weeds from the site is not necessarily <br /> desirable, so we will be using controls on the noxious weeds and <br /> letting the rest grow in select areas for limited times as long <br /> as they do not hamper the grass growth. It may be necessary to <br /> control weeds by mowing after the first year, the feasibility of <br /> chemical weed control methods will be studied should other forms <br /> not work. Control of noxious weeds is important to the state so <br /> USDA Extension Service recommendations will be followed to <br /> control them. <br /> IRRIGATION <br /> No irrigation is planned for the revegetated area in the <br /> pit . It makes the vegetation dependent on water and does not <br /> promote a vegetation cover that is diverse and capable of self <br /> regeneration. <br /> RECLAMATION PERFORMANCE STANDARDS <br /> The operator intends to mine the property in compliance with <br /> the Reclamation Performance Standards of Rule 3 . Grading will be <br /> done to create a final topography that is compatible with the <br /> intended final land use . Most slope areas will be created by <br /> backfilling to the final slope rate . These slopes will be 3 : 1 <br /> and we will attempt to retain the present drainage pattern across <br /> the property. A sign that conforms to the requirements in Rule <br /> 3 . 1 . 12 (1996) is in place at the entrance to this facility. <br /> The material used to create the slopes will be native <br /> overburden material found on the site at this time . It will <br /> consist of sand, gravel, overburden and topsoil . The pit will be <br /> reclaimed so that a suitable grade for drainage exists that <br /> matches the premining pattern. All surface runoff from reclaimed <br /> 16 <br />
