MMRR Quarry, M-2004-067 Response to Sept. 20, 2005 Adequacy Review October 24, 2005 Page 3 intent of monitoring is to minimize the potential for blasting to generate a dust source. The most direct measurement of wind speed for this purpose is at the ground elevation. The Applicant submits that it will provide adequate facilities to monitor and record wind speeds on the site during blasting. The Applicant does not oppose location of a wind gauge at any location that is accessible for service and monitoring and representative of the potential for blasting to generate a dust source; however, any specific stipulations regarding the location of monitoring equipment relative to a hypothetical dust plume should be deferred to the air quality permit process. C. Pre-Mining & Mining Plan Maps -Per Rule 6.4.3(g), the Applicant will research the physical location of the Silver Dollar Metro District light poles and revise the permit maps, as necessary, to show the location of light poles if they occur within 200 feet of the affected land of the MMRR Quarry operation. (Affected land includes the quarry access road off State Highway 119). Please clarify whether the light poles occur within 200 feet of the proposed affected land under either scenario "I3" or "C". Please respond. It is has been the Applicant's understanding from the time of the initial submittal of the MMRR Quarry application that certain light poles are within 200 feet of the quarry access road. The Applicant has therefore disclosed the existence of light poles on all appropriate drawings and Exhibits and, pursuant to Rule 6.4.19, has additionally sought to reach an agreement regarding reimbursement or repair for structural damage to these light poles due to mining operations. The Applicant has re-verified the field location of these poles. Revised Exhibit C (dated 9/23/05) is enclosed, reflecting the accurate location of these poles on the current basemap. Finally, we reiterate that the existence of light poles in the vicinity of the proposed point of access has been part of the record of this review process since the initial submittal. A question regarding the ownership of those light poles has since been raised (see below for the response to comments from the City of Black Hawk), but light poles have been a mapped feature of Exhibit C since the initial application, consistent with Rule 6.4.3(g). Ownership of the light poles is discussed further below. D. Exhibit S - If the Silver Dollar Metro District light poles, as noted in Item C above, occur within 200 feet of the proposed affected land with access point "C'; the Applicant will need to demonstrate compliance with Rule 6.4.19. Please respond. Regarding the ownership of light poles in the vicinity of the affected land, please see the Applicant's response below to comments from the City of Black Hawk.
