indicates that all storm water will be retained on site. However, the means to be employed in retaining all storm water on site are not specified. The applicant should indicate what storm-water controls will be employed and where located in 1t,' order [o retain all storm water on site. The applicant should also indicate intention to contact with the State y1fi Engineer's Office in regard to whether any water rights issues are involved when it is the applicant's proposal [o retain all storm water runoff on site. ~N' EXHIBIT C (Rule 6.3.3(k)): The proposed mining plan does not respond [o the requirements of [his Rule, G,~ i.e. indicate if any refuse or acid or toxic producing materials will be encountered and, if so, how [hey shall be handled and disposed of. The applicant must respond to the requirements of this Rule. EXHIBIT C (Rules 6.3.3 (n) and (o)): There are no responses to the requirements of these Rules included in the proposed mining plan, i.e. no listing of any secondary commodities or incidental products [o be extracted ~c by the proposed operation. The applicant must respond to the requirements of these Rules. If [here are no secondary commodities or incidental products to be extracted, this should be clearly stated. EXHIBIT D (Rule 6.3.4(1)( c)(i)): The SCD survey indicates that the surface layer of the Curecanti loam is up to IS inches thick so the Division is no[ willing [o accept that there may be no topsoil available at the site and none may be salvaged. The statement included under this Exhibit [hat the average depth of replaced topsoil will be 6.0 inches seems reasonable. Even the 4 inches of topsoil mentioned under the Reclamation Cost estimate could be accepted. In addition, the Division does not understand the statement that the average depth of replaced topsoil will be 6.0 inches on [he area north of the road. The applicant must commit [o a thickness of plant growth medium to be replaced that is consistent with [he soils information supplied under Exhibit B and explain what the "area north of the road" means. Topsoil, when salvaged and stockpiled for reclamation purposes, should be adequate to cover all the disturbed area from which it was removed, not just a portion. EXHIBIT D (Rule 6.3.4(1)( c)(v)): The reclamation plan proposed by the applicant indicates that one and one half to two tons of straw mulch would be used in reclamation. The MRCS plan indicates 2 tons of grass hay. The conflict should be resolved. The applicant should indicate which of these two statements is intended to be the commitment. EXHIBIT D (Rule 6.3.4(1)(e)): There is no mention in the proposed reclamation plan of the treatment of the areas compacted by traffic or by the stockpiling of materials. /~ The applicant should respond fully to the requirements of [his Rule. EXHIBIT D (Rule 6.3.4 (1)(f)): The Division has made its own estimate of the cost of reclaiming the disturbance associated with the proposed operation, based to the extent possible on the data provided with the applicant's cost estimate and on other information included in the application. A copy of the Division's estimate is attached to this review and indicates that a Financial Warranty of $16,600.00 is necessary to reclaim the disturbance anticipated to accompany the proposed operation. The Division's assumptions for its estimate are as follows: BASIC ASSUMPTIONS: Based on the information supplied under the applicant's cos[ estimate and elsewhere in the application, the Division's estimate includes salvage by the applicant of both topsoil and subsoil from an area of 9.02 acres involving a pit averaging some 820 feet by 480 feet in size with the •_ ~i stockpiles of topsoil and subsoil located at [he southern end of [he pi[. Based on its own information, the ` Division has assumed swell factors of 1.15 and 1.25 for the topsoil and subsoil, respectively. The Division's (~( estimate involves use of a DS dozer with a 3-shank ripper accompanied to the site by fuel and lobe trucks. V'~` 4 TASK 1 (Spread subsoiVoverburden): The SCD information included under Exhibit B indicates that '~1 the surface layer of the Curecanti loam is about 14 inches thick and [he subsoil possibly 23 inches thick. The ~(DI applicant has committed to salvage both surface layer/topsoil and subsoil, stockpile both and spread both in conjunction with [he reclamation. As a result the Division has assumed an average of 4 inches of subsoil will be salvaged over an area of 9.02 acres and stockpiled at the southern end of the pit which then involves a push distance averaging approximately 400 feet.
