<br />increased vegetation establishment on the flatter slopes. Please <br />clarify the application so that the regraded slope gradients are <br />consistent throughout the application. If steeper than 3H:1V <br />slopes are desired, provide the justification to be inserted into <br />Exhibit D. <br />Exhibit D-Revegetation <br />Under Exhibit D (1)(c)(v) it is stated that a straw mulch will be <br />applied at a rate of 2,000 pounds per acre. The MRCS letter <br />recommends straw mulch at a rate of 4,000 pounds per acre which is <br />an accepted standard rate. The NRCS letter also suggested a manure <br />application of twenty tons per acre or a commercial fertilizer <br />application of around 40 pounds per acre for both nitrogen and <br />phosphorus. Does the operator plan to amend the soil with either <br />of these options. If not, a commitment to sampling the soil for <br />fertility levels prior to seeding should be added to the <br />application. The soil could then be amended as appropriate prior <br />to seeding. Also, under (i) a commitment to replacing at least 6 <br />inches of topsoil must be added. <br />Exhibit D-Reclamation Cost Estimate <br />The reclamation cost estimate will need to be revised to add an <br />additional ton of mulch per acre plus fertilizer costs. In <br />addition the topsoil replacement costs are inadequate. The <br />Division's estimate to the soil utilizing a scraper (which is the <br />least expensive method) is approximately $0.70/yard. The worst <br />case disturbance presented in the reclamation plan will have 3000 <br />cubic yards of topsoil to replace which equals $2100 or <br />approximately $233/acre. Inserting these additional costs brings <br />the total cost of reclaiming the mine to $623/acre. For 9 acres <br />this equals $5607. Adding the required overhead burden of 23.5$ <br />brings the total reclamation bond up to $6925.00. This figure will <br />be subject to change, pending the outcome of the state engineers <br />review. <br />This concludes the initial review of this application. If you have <br />any questions, please contact me. Otherwise, we will look forward <br />to receiving your responses prior to the decision date of September <br />5, 1996. <br />Sincerely, <br />~~~ <br />J Anthony J.
