Box 1193 Canon City, CO 81215-1193 State of Colorado Division of Minerals and Geology 1313 Sherman Street, Room 215 Denver, CO 80203 • III IIIIIIIIIIIII III III IIIIIIIIIIIII III sss ~G~~t~~~ v ~• RE: Agile Stone Systems, Inc. - Parkdale Project 112 Permit Application, File #M-97-054 Informal Conference, September 18, ] 997 Deaz Sirs; In the above-mentioned cause I hereby respectfully petition the Division of Minerals and Geology to request that Applicant, Agile Stone Systems, Inc., provide a complete Geotechnical Evaluation of all geologic hazazds within or in the vicinity of the affected lands, that may be de-stabilized or exacerbated by mining or reclamation activities. Furthermore, [request that Applicant be required to provide a complete Engineering Stability Auatyses for the slope configurations as they will occur during operations. Such Analysis should include at the very least a slope stability analysis for the area undergoing the blasting as well as for the neighboring mountain ranges that will be m the line of the blasting. Please refer to your Construction Materials Manual, Page 113, Rule 6.5 regarding the submission of a Geotechnical Stability Exhibit. In defense of my request and my position that this is an unstable area I have attached a full color geological map of the azea in question (a small portion of the Geologic Map of the Pueblo 1 ° x 2° Quadrangle, South Central Colorado) along with a black and white copy of the same geological area which show at least three fault lines converging around Cactus Mountain on which the Applicant is proposing to blast. The major fault lines converging upon and surrounding this area are: Currant Creek-Isle Fault Zone to the West, The Parkdale Fault which surrounds the Northern flank of the mountain and the Mikesell Gulch Fault to the East. In addition there are many fissures leading off of these fault lines. The potential for seismic activity is present due to the configuration of these many fault lines. Stated in your Construction Materials Manual, Rule 6.5, Paragraph (4) is that "the Applicant shall demonstrate through appropriate blasting, vibration, geotechnical, and structural engineering analyses, that off-site azeas will not be adversely affected by blasting". I respectfully request that you do insure that this portion of your requirements is a part of the permitting process for Applicant. And that the persons doing such analyses are properly licensed.
