reclamation/revegetation recommendations for the site. Theirrevised recommendations will be included in <br />the forthcoming permit amendment application. <br />Item No. 17 <br />The closure plan states "the surface is graded nearly flat with sufficient slope to prevent ponding of <br />rainfall on top of the CKD disposal area. What will that slope be? <br />The slope of the reclaimed areas will be approximately 1-3%. <br />Item No. 18 <br />Construction activities such as road building may be contemplated by persons operating the mine in the <br />future. Please describe how the CKD disposal areas will be permanently and easily, identifiably marked <br />so that future earthmoving projects in the area can be planned considering the location of the CKD <br />disposal areas. <br />Holnam will be installing permanent metal signs around the perimeter of the CKD disposal area alerting <br />people that CKD is buried in the area and they should contact the Quarry Manager before digging. The <br />signs will be attached to steel posts, which will be permanently cemented into place and will be spaced <br />every 100-300 feet. It is anticipated that this can be accomplished by September 30, 2001. <br />Item No. 19 <br />Does Holnam commit to the NRCS's recommendations onPage 4 of your application regarding mulching <br />and fertilization? <br />Yes, Holnam will be following the MRCS recommendations. <br />Item No.20 <br />Three (3) to 10 foot berms are placed between the relatively flat reclaimed areas and adjacent slopes of <br />areas being actively mined, or not yet reclaimed, to help prevent erosion. Are any of these berms <br />permanent features of the reclamation plan? If so, please show their location(s) on a TR-6 map and <br />describe them in terms of their cross-sectional area, final reclamation, and grade of any water diversions <br />and their outlets. <br />No, these berms are temporary and are removed during final reclamation of an area once they aze not <br />needed for runoff and erosion control. <br />Item No. 21 <br />Page 4, Section 3.3 of the "Hydrogeologic Assessment Report" states that a water well survey was <br />conducted including acquiring information from the State Engineer's Office. What was the result of the <br />survey? <br />The results of [he survey indicated the existence of water wells in the general area. However, none of the <br />wells were close enough to the site to provide data representative of the ground water conditions in the <br />quarry. <br />
