drainage or collection channels, sediment ponds, spillways, riprap pads, check dams, culverts, etc. The <br />• certification should be submitted within 60 days of completion of all hydraulic structures and verify that all <br />such structures were properly installed according to the designs provided in the mining and reclamation <br />permit. Please respond. <br />21. Blasting Plan - Review comments from Allen Sorenson will be forwazded to the'Applicant as soon as <br />they become available. <br />Also, it is the Division's expectation that the applicant/operator develop a blasting method or blasting <br />pattern such that radioactivity levels in blasting dust will not exceed applicable radiation levels in the blast <br />dust at their pemtit boundary. Therefore, the Division suggests the Applicant provide a plan that <br />minimizes, to the extent possible, the potential for generation and transport of radioactive dust. Such plan <br />must include Best Management Practices (BMP's) to be implemented prior to, during, and after blasting <br />operations. Please respond. <br />Uranium Mineralization -Radiation <br />22. The Applicant has proposed a Monitoring, Containment, and Control Plan to address the potential for <br />adverse impacts to human health, and the environment from radiation resulting from quarrying activities <br />and to ensure the operator's compliance with all applicable Federal, State, and local regulations. The <br />Applicant has also stated that they will apply for a CDPS discharge permit at the appropriate time (prior to <br />any discharge from the mining operation). The Division requests that the Applicant commit to providing <br />written demonstration of an approved CDPS discharge permit from the Colorado Water Quality Control <br />Division prior to any offsite dischazge or prior to the initiation of any blasting and quarrying activities, <br />• whichover comes first. Please respond. <br />26. The Applicant has committed to monitor all on-site water holding structures for radioactivity, and has <br />proposed that if exceedances of WQCD water quality standazds occur for three consecutive monitoring <br />periods that the Applicant will analyze the source of the exceedances and remove the source rock to the <br />quarry reclamation process. The Division requests that the Applicant commit to the following measures: If <br />an exceedance of an agreed upon WQCD water quality radiation standard occurs, the Applicant/Operator <br />will immediately re-sample the effluent to confirm whether an exceedance has occurred, and if the 2nd <br />analysis affirms that an exceedance of an agreed upon WQCD water quality radiation standard has <br />occurced, then the Applicant will submit to the Division a mitigation plan within 10 working days of the <br />confirmed exceedance. Please respond. <br />6.4.12 EXHIBIT L -Reclamation Costs <br />40. In conformance with Rule 6.4.12(1), the Division has calculated a total reclamation cost of $903,800. <br />Included in this estimate is an itemized cost for backfilling and grading shot rock at the base of the <br />highwall and bench sequence from a 1:1 slope to a 3:1 slope at a cost of $0.313/cy of shot rock. This <br />itemized cost eliminates the need for an itemized cost to transport the shot rock to the waste rock disposal <br />azea for final reclamation. Please see attached reclamation cost estimate. Please advise the Division if any <br />of the acreages used in the estimate need to be revised. <br /> <br />
