<br />in the permit, the following stipulation is necessary: <br />Stipulation No. 8 <br />PRIOR TO CONDUCTING ANY BLASTING OPERATIONS, THE PERMITTEE <br />WILL CONDUCT THE NECESSARY PRE-BLASTING SURVEYS AS PRESENTED <br />ON PAGES 4-63 AND 4-63A OF VOLUME I OF THE APPROVED PERMIT <br />APPLICATION." <br />SRM Response: <br />Storm Ring Mines will commit to the pre-blast survey as outlined <br />on pages 4-63 and 4-63a. It should be noted, however, that <br />during blasting in Phase "A", there are no structures within <br />one-half mile of the proposed site. As a good neighbor approach, <br />Storm Ring would be more that agreeable to perform the survey for <br />the dwellings which lie in the general proximity of the blasting <br />area. <br />19) Ref: Coal P o GG~ng and Non-Coal Processing Waste - <br />MLR Comments: <br />"The Division cannot presently write findings for this section. <br />The following are the Division's comments: <br />The applicant has responded to our comments contained within our <br />earlier adequacy review, which dealt with deficiencies contained <br />in Appendix 2.2-3a. The amendments are made in the form of <br />amended pages to the original consultant's report, prepared by <br />Chen and Associates, Inc. The applicant should submit a <br />certification statement prepared by Chen and Associates which <br />certifies the consultant's authorship of the amendments. The <br />following comments assume receipt of that certification <br />statement. <br />(1) The applicant has performed a pseudo-static seismic stability <br />analysis of the proposed life-of-mine configuration for the <br />390' high coal processing waste slurry embankment. The <br />applicant has applied a horizontal acceleration factor of <br />9.1, as recommended by Mr. Rahe Junge of the Colorado <br />Geological Survey. Unfortunately, the analysis performed <br />determined the pseudo-static slope stability safety factor of <br />the life-of-mine structure to be 1.1. Rule 4.11.5(3)(a)(ii) <br />specifically requires that the seimsmic safety factor for <br />such structures "be at least 1.2". The applicant will have <br />to amend the engineered design, in order to achieve the <br />required seismic safety factor. <br />
