AUGUST 8, 2011 <br />M.- y DAY MINE: CLASS 11— SUBMITTAL 2 REVIEW <br />P.vGi 13 Or 15 <br />/4. The Geotechnical Work Plan states that an outlet structure will not be installed on the 36" <br />culvert at the base of the road due to wetlands. Evaluate and provide a design for the culvert <br />inlet <br />/ <br />I 7. <br />to ensure than no sediment enters the culvert becoming a point discharge to wetlands. <br />6. Show how erosion and sediment control will be handled at the materials staging area(in the <br />f floodplain) at the base of the new. unpermitted access road. <br />Address how oil, fuel, and chemical spills on the access road (new, unpermitted portion or <br />historic portion) will be handled, with consideration for spills that may occur during <br />precipitation events. <br />J 8. The drainage evaluation shall be prepared, bound, and sealed by a Professional Engineer <br />registered in the Slate of Colorado. <br />/9. LPLUC 74 -112 to 114 and 82 -169 addressing drainage report contents are attached for <br />reference <br />s! E. DRMS approval of the road plans <br />v/ F. Justification Regarding Safety of the Road for its intended uses is needed. This may be based on <br />MSHA, DRMS, or other relevant agency regulations and review. <br />f G. Response to all seven variance criteria as outlined in LPLUC 66 -26 <br />V. / Submittals Requested in Previous Review for Class II Permit (and still needed) <br />New clarifying notes are provided in italics. <br />A. Revise narrative to address the following: <br />1. Water supply (summary level only addressing key components as outlined in this letter) rY Y g Y P ) <br />2. Traffic projected on CR 124 and on the project access roads - including current existing traffic / <br />and proposed project traffic <br />3. Access to the site — road grades, turn radius, design vehicles and loads, acceptable uses for the <br />unpermitted and historic portions of the road. <br />4. Parking. LPLUC 82 -175 requires 1 space /employee plus adequate loading area. <br />5. Service vehicles anticipated and access to site (ie: construction, fuel, chemical deliveries; <br />sanitary service; emergency service) <br />6. Sewer service at the site <br />7. Emergency service at the site <br />8. Snow management: Where will snow be stored? <br />9. Crusher operation proposed_ for the second staging area at the base of the new, unpermitted <br />access road. Address crusher activity, impacts, and mitigation.. <br />10. Additionally, please review the above "Project Understanding" and "Engineering Issues" and <br />provide any corrections, additions or clarifications needed. <br />PLANNING Dl?P.\RTNIENT • 970.382.6263 . • 1060 E. 2ND AVi . • DUR:\NGO, Cc • 81301 <br />
