14.) Noxious weeds have been observed at the site such as Tamarisk trees (Tamarix sp.). <br />Please submit a weed management plan for this site. This plan shall include a monitoring plan <br />designed for the life of the mine for noxious weeds, specific control measures that may be <br />applied, and a post treatment monitoring plan. This plan should be developed in consultation <br />with the county extension agency, or weed control district office. <br />15.) Please explain how the seedbed will be prepared for seeding. <br />16.) Topsoil appears to be stockpiled for longer than 180 days at this operation, thus vegetation <br />will need to be established on these piles to prevent damage from wind and water erosion. <br />Please explain how the stockpiles will be protected from wind and water erosion, and provide a <br />seed mixture that will be used to establish vegetation on the stockpiles. <br />17.) Please explain how the access road will be reclaimed, or will it be left in place after <br />reclamation? If it will remain in place after the site is reclaimed, please state how long the road <br />will be and how wide it will be. <br />18.) Please state if fertilizer will be used for reclamation, if so; please state the type of fertilizer <br />and the amount that will be applied per acre. <br />Rule 6.4.6 Exhibit F - Reclamation Plan Map: <br />19.) The Reclamation Plan Map depicts a 15 foot pit excavation with reclaimed side slopes set <br />approximately an 8.5:1 to an 9:1 horizontal to vertical ratio. The current pit excavation seems <br />deeper than 15 feet in places and the mining plan would indicate a 25 foot pit excavation. Is <br />this the expected physical appearance of the affected land after the site has been reclaimed? <br />Or, will the pit be deeper and the side slopes steeper? <br />20.) Please portray the proposed final land use (Rangeland) for the entire affected area. <br />Rule 6.4.7 Exhibit G - Water Information: <br />21.) Item (1) indicates that the operation will not affect the surface water system; however this <br />does not appear to be the case. It would appear that groundwater is impounded in the pit <br />excavation for longer than the allowed 72 hours. Please address the issue cited in the Division <br />Item #5 above for Exhibit D. <br />Rule 6.4.12 Exhibit L- Reclamation Costs: <br />22.) Item 1 indicates that the remaining highwall is 400 Linear Feet; based on the field <br />inspection conducted on October 6th, 2008 the highwall runs almost the entire perimeter of the <br />pit excavation approximately 2,000 feet. The 400 foot estimate does not appear accurate.
