Is there any of <br />that material stockpiled presently? If not, how will the final <br />area be reclaimed? The eastern end where the scales are located <br />appears to be located within the 1994 reclamation area. How will~,~ <br />the scales be accessed? Will the reclaimed area be redisturbed? <br />The application also mentions a second access point between the pit <br />and Highway 50, but its location is not apparent from the plan or <br />}jU the map in Exhibit E. Will there be any needed reclamation <br />~+associated with that access, involving fill material or a culvert, <br />for example? The present pit is described as 20 feet deep and two <br />acres large. Will it be enlarged or deepened? What will be its <br />slope angles during mining? <br />Exhibit D - Reclamation Plan <br />The plan states that nitrogen and phosphate fertilizer will be <br />applied as needed. How will that need be determined? If the soil <br />material that is to be placed on the surface of all reclaimed areas <br />is too rocky, chiseling it during reclamation may bring too many <br />rocks to the surface. You might want to rip the area prior to soil <br />replacement, then decide whether chiseling is still necessary, <br />especially since the mulch will be disced in. There is mention of <br />replacing soil on the southern portions of the permit. Are the <br />S<<~~ other portions going to be topsoiled, or revegetated? You provide <br />~~~ ~ a seedmix that was used for offsite disturbance, but it is not <br />I ~ clear whether it is to be used for reclaiming areas inside the <br />permit also. Grading work and demolition during reclamation must <br />also consider drainage of the site, road shoulders if affected, <br />removal of the scalehouse and its foundation, and scale removal <br />including any abutments. Will any disposal costs be included, or <br />will materials simply be backfilled in the pit? <br />Reclamation costs do not apparently include rough grading, slope <br />reduction (if mining slopes are steeper than reclaimed slopes), or <br />backfilling. Which roads are to be reclaimed? Compacted areas may <br />need to be ripped. Please also consider addressing costs for <br />drainage structure removal and road shouldering or surfacing. <br />Exhibit E - Maps <br />The Mine Plan Map does not appear to represent the direction of <br />surface drainage, with arrows pointing uphill. It was stated <br />earlier that there is a pit presently onsite, but the contours do <br />not show it and the direction of mining is not shown. If there are <br />any structures you identified in Exhibit B, please depict them on <br />the map. <br />The Reclamation Plan Map does not depict a pit in the surface <br />contours. Is it to be totally backfilled? If there are to be <br />
