• The Appendix CC-10, Section 3 regulations require a substantial amount of information, presumably anticipating mining proposals in new or green fields areas. The MLE is an extension of the existing Cresson mine, within approved permit boundaries, using approved mining and reclamation practices. Much of this information is duplicative of that previously provided under the Amendment No. 8 and associated Technical Revisions. Key information required for this submittal is brought forward while other information is provided through specific reference to the Amendment No. 8 application or provided in the attached OMLR application. Due to the quantity of information required to be provided, and specifically because much of the information pertains to an already approved and operating property, CC&V requests those third parties reviewing the project with Teller County recognize that the approved Cresson Project is not the subject of this submittal, rather it is the proposed MLE activities. CC&V requests your assistance in providing this guidance. The Project Elements The proposed MLE activities are internal to the Mining Overlay District Boundary. Land included within the MLE Permit Boundary is owned or controlled by CC&V unless otherwise shown. Land ownership is described in Attachment 1, Table 2 to this application. Portions of the MLE affected areas are located closer to the permit boundary and closer to habitable structures than previous activities in the permit area, hence noise analyses, noise • mitigations and noise monitoring are provided to assure compliance with the stipulated residential noise standards. A noise report is provided as Attachment 8. There are changes to traffic patterns on public roads associated with implementation of the MLE and relocations and realignments and upgrades to Teller County roads will be required. A revised traffic study is provided as Attachment 5 to address these changes. Blasting and associated seismic monitoring will continue as per approved practices. Specific blasting scaled distance information has been developed for the Amendment No. 8 Cresson Project and is applicable to the proposed MLE activities. Additional blast monitoring is recommended and proposed for the Cripple Creek side of the project in the attached OMLR application. Air quality is regulated under CC&V's facility wide air quality permit issued by the Colorado Department of Public Health and Environment. CC&V continues to monitor air quality at the Rigi Monitoring Station in accordance with the monitoring requirements of the permit. An application for modification of the air quality permit is being requested as part of this permitting. As discussed in Attachment 1 of this application Teller County will be kept informed of permit changes with copies of any new issued permits provided within 30 days of issuance. There are no new proposed water discharge permits or water related permits required for the MLE. The site wide storm water designs have been updated and the design report is included • with the application plan as Attachment 10. The Storm Water Management Plan will be updated to address changes in the mining plan.
