wastewater treatment plant and its associated buildings, Cieaz Creek Convenience Store <br />sewage lines and improvements, Silver Dollaz Metropolitan District light poles and utility <br />lines along Colorado Highway 119. In addition, the Applicant has committed to <br />conducting pre-blast surveys of potentially affected structures pursuant to Division rules, <br />with notices and survey requests to be sent to the owners of such structures at least 30 <br />days prior to blasting. The surveys will be completed and submitted to the Division prior <br />to initiation of blasting. <br />11. Party objectors Black Hawk/Central City Sanitation District and Silver Dollaz <br />Metropolitan District commissioned a sepazate blast vibration analysis prepazed by <br />7oseph Bernosky of Leonard Rice Engineers, Inc. dated November 10, 2005 ("Rice <br />Report"). The Rice Report analyzes the risk from blasting activities to the Black <br />Hawk/Central City Sanitation District's wastewater treatment plant, located across <br />Highway 119 from the proposed quarry, and the Silver Dollaz Metropolitan District's <br />lighting structures, located adjacent to Highway 119. The Rice Report concludes that <br />these facilities are far more sensitive receptors than the residential structures used as <br />baseline indicators in standazd blasting analyses and that biasting vibrations from mining <br />operations pose a threat to components of the wastewater treatment plant and light <br />poles lamps. <br />12. Irr a review of the Rice Report prepazed by a Division specialist on November 21, 2005, <br />the Division concludes that there is no possibility, absent anon-compliant event, that <br />vibration levels will exceed commonly acceptable levels. The Division's analysis also <br />concludes that if the wastewater treatment plant and light poles aze vulnerable to damage <br />from proposed blasting, they are much more vulnerable to ordinary daily vibrations <br />MMRR Board Order, M-2004-067 <br />
