Letter to Ryan J. McHale 4 February 16, 2010 <br />Permit Application Adequacy Review File No M-2009-076 <br />and a cost for execution of the removal must be provided. It has been the direct experience of the DMRS <br />that trailers and other equipment, chemicals, including those in unopened packages, fuel, unused and waste <br />oil, antifreeze, etc. left at sites that are subject to bond forfeiture are worthless and are frequently creating a <br />hazard or nuisance. Therefore, the cost analysis must be predicated on disposal at a permitted dump. A plan <br />and estimated costs for grading, placement of plant growth media, and revegetation for the mobile mill site <br />must also be provided. <br />d. Venture Resources states that any mill feed rock at the mobile mill site will be consumed in the mill prior to <br />the commencement of reclamation. It has been the direct experience of the DRMS that mines that go to <br />bond forfeiture are frequently subject to disorderly termination by the operators. Therefore, sufficient bond <br />must be posted assuming there will be mill feed in the crusher feed pile and bin, and in the crushed rock bin <br />(287 tons total), and that there will be concentrates (48 cy) stored on site at the time of forfeiture. A plan <br />and estimated costs for removal and proper disposal of these materials must be provided. <br />12. Exhibit D states that pre-existing mine waste rock piles that are not disturbed during the course of Venture <br />Resources operations will not be subject to reclamation requirements. DRMS agrees with this position. <br />However, for partially excavated waste rock piles, if any were to remain at the termination of operations, the <br />excavated area must be reclaimed. A plan for this reclamation must be provided with an estimate for the cost <br />to execute the plan. The plan and costs must be predicated on an enforceable limitation to the area of the waste <br />rock piles that will be under excavation at any time during the course of operations. <br />13. Exhibit D states that a 1:5 ratio, by volume of class A biosolids and wood chips will be applied as a plant <br />growth medium to the tailing impoundment. This volume of wood is unacceptable in plant growth medium <br />because it will consume and tie up the plant available nitrogen, and because it is likely that wood or some <br />similar bulking agent will have already been incorporated into the biosolids during composting. As discussed <br />previously, the NRCS soil survey for this location indicates that there is salvageable soil available. The DRMS <br />will require that the soil be salvaged from the disturbed areas; it is acceptable to salvage and combine all soil <br />horizons. The salvaged soil can then be spread and top dressed with class A biosolids to create a superior plant <br />growth medium. The amount of biosolids amendment to be used should be based on soil testing to target three <br />percent organic content in the amended soil. For cost estimation and bonding purposes, biosolids at forty tons <br />per acre is appropriate. Provide a plan for soil salvage and stockpiling, and a plan and estimated costs for <br />amending the stockpiled soil with biosolids and placement into the areas to be reclaimed. DRMS will require <br />that the unit cost for biosolids at $50 per ton delivered be input to the estimate. <br />14. The DRMS accepts the phased approach to bonding described in Exhibit D. Considerable additional <br />information, as described in this letter, is needed before the DRMS can prepare an independent cost estimate <br />for this project. Two issues to be addressed relative to the Venture Resources estimate are the cost of reseeding <br />previously reclaimed areas where vegetation has not sufficiently established, and the cost for weed control <br />measures that are likely to be necessary. For cost estimation and bonding purposes, assuming that fifty percent <br />of the previously reclaimed area will require reseeding is appropriate, and a weed control cost at $200.00 per <br />acre over the entire affected acreage is required. <br />15. Exhibit F states that no well permits are required; Venture Resources must contact the Office of the State <br />Engineer to ascertain if permits are required for the monitoring wells. Exhibit F states that no effluent <br />discharge permit is required; Venture Resources must contact the Water Quality Control Division (WQCD) to <br />ascertain if a storm water permit is required. Exhibit F does not list a Department of the Army Permit for work
