10. The Applicant has stated processing materials, recycling facilities/plant, concrete <br />plant and asphalt plant locations will be addressed under a subsequent Technical <br />Revision to the approved permit. The Division recommends addressing these <br />components of the mine operation during the permit review process. Any operational <br />changes that may occur in the future could then be modified through a Technical <br />Revision. <br />11. The Mining Plan states extraction will occur within 10 feet of man made structures, <br />easements and right-of-ways and within 25 feet of above ground oil and gas facilities. <br />The Division requires a 200 foot setback from every permanent man-made structure <br />unless an executed damage waiver agreement has been submitted as required by Rule <br />6.4.19(a). If an agreement cannot be reached then an engineering evaluation can be <br />used to demonstrate that mining will not result in structural damage per Rule <br />6.4.19(b). Please be aware that the Division will not accept an engineering evaluation <br />until the Applicant has demonstrated they have attempted to obtain damage waiver <br />agreements from the structure owners. The Applicant can demonstrate compliance <br />with Rule 6.4.19(b) by submitting copies of the damage waivers and return receipts of <br />a Certified mailing or personal service. <br />12. The Applicant has stated extraction will occur within 25 feet of above ground oil and <br />gas facilities. Please clarify if extraction will occur within 10 feet of underground oil <br />and gas facilities/structures. <br />13. Please describe all haul roads that will be utilized for the mining operation. Provide <br />the dimensions of all haul roads and specify if they are to remain upon the completion <br />of mining. <br />14. The Applicant will need to provide a flooding impact analysis characterizing the <br />floodpath and flow velocities for flooding events expected during the life of the <br />operation. The Applicant will need to assess how much of the pit or reservoirs will be <br />flooded, how the flood waters will be safely returned back to the main channel of the <br />Cache La Poudre, and how the riverbank and pitside banks will be protected from <br />excessive erosion. <br />6.4.5 Exhibit E - Reclamation Plan <br />15. The Reclamation Plan calls for reclaiming pit slopes to 3H:1 V by pushing the pit <br />bottom with a dozer until the resulting pit slopes conform with Rule 3.1.5(7). In <br />addition, the Applicant has stated the pit will be dry mined to a depth of 40 feet and <br />extraction occurring deeper than 40 feet may be done under wet conditions using a <br />dredge. Please describe how the pit slopes will be reclaimed to 3H:1 V under wet <br />mining conditions. <br />16. The Applicant has provided a Backfill Notice as part of the application. In accordance <br />with Rule 3.1.5(9), the Applicant must submit the following additional information:
