Mr. Burke Lokey ' -2- December 9, 1983 <br />3. Due to the sporadic nature of county operations, the operator <br />is directed to Rule 1.6 (speclflcally Rule 1.62) of the Rules and <br />Regulations pertaining to temporary cessation. If any part of this <br />rule and regulation is applicable to Mesa County, please specify <br />the applicable statements. <br />4. To what depth will mining occur? <br />5. Has the access roads to each site been included as permitted <br />acreage? If the access road is specifically for the mine, 1t must <br />be included as permitted, affected acreage (please change the <br />acreage amount accordingly). If, however, the access road was <br />already present and is not speclflcally for the mine site, it does <br />not have to be included as permitted acreage. <br />6. The following questions pertaining to the topsoil stockpiles. <br />A. Where will the stockpile(s) be located in the future? <br />B. What are the slope gradients for the stockpile(s)? The <br />Division recommends a gradient no steeper than 3h:ly. <br />C. If the sto<kpile(s) is to last for more than one growing <br />season, it muss: be seeded to maintain soil quality and soil <br />quantity. Whai: seed mixture will be used and at what rate <br />will the species be planted? The Division recommends a seed <br />mixture incorporating at least two different grass species <br />and, if possible, a legume species. <br />B. Exhibit D - Soils and Vegetation Information <br />1. The soils and vegetation Information provided for this exhibit <br />is lacking in detail. Site specific soils information 1s needed, <br />as can be obtained from the applicable Soil Conservation Service <br />Soils Survey, and site specific vegetation information (percent <br />cover) is required, as can be obtained from the Soil Conservation <br />Service (request a completed CO-ECS-2 form). <br />D. Exhibit E - Rec"lamation Plan <br />1. It is stated in each of the applications that reclaimed slopes <br />would be graded to 3ti:ly or to existing natural slopes in the area, <br />whichever applies. Nlesa County needs to specify the existing <br />natural slopes at each of the mine sites so that the Division is <br />aware of the maximum reclaimable slope. <br />2. Does the County plan to use any mulches or fertilizers at the <br />site? If so, please specify type and rate of the mulch and <br />fertilizer. (If the fertilizer rate is unknown, the County could <br />specify no rate of application but that prior to seeding, soil <br />samples and appropriate soil tests would be taken and the <br />appropriate amount would be applied.) <br />
