(7) On Page D -1, Paragraph 2, it notes that water diversions and impoundments are covered under <br />the attached EPP. Per Rule 6.4.7(2) all structures need to be clearly identified and shown on the <br />Exhibit C - Mining Plan Map. The submitted Exhibit C maps do not clearly show these structures. <br />(8) The language on Page D -1, Paragraph 3, and elsewhere is confusing. While it understood the <br />upper mine area is not in the immediate plans, structures and disturbances for this area are <br />outlined in the mine plan, reclamation plan, and the reclamation cost exhibits. If Cotter wishes <br />to include the proposed operations for the upper mine area in the permit now, all required <br />information, including all EPP requirements for these operations must be addressed in this <br />amendment. Otherwise, any references to the upper mine area proposed operations should be <br />deleted from the current submittal and resubmitted in a future amendment. <br />(9) Per Rule 3.1.5 (5), Materials Handling, all toxic producing materials that have been mined shall <br />be handled and disposed of in a manner that will control unsightliness and protect the drainage <br />system from pollution. Please provide details of how high grade and low grade ores are handled <br />and best management practices to prevent ore cross contamination with waste rock. <br />(10)The lower mine area is on patented claims and not under the jurisdiction of the DOE. Therefore <br />the requirements for reclamation shall meet the specifications of the Act and Rules of the State <br />of Colorado and the issued reclamation permit. Therefore, please remove or revise the <br />statement in Exhibit E, Page E -1, Paragraph 1, which states Cotter will restore the affected areas <br />in accordance primarily with DOE lease requirements for 1D -8. <br />(11)On Page E -1, Paragraph 5, there is a lengthy discussion of reclamation of the upper mine area. If <br />the area is only a potential disturbance then the details of reclamation are confusing to the <br />current plan. Please see comment no. 8 above. If proposed plans for mining operations in the <br />upper mine area are to be included in AM -01, those plans must include descriptions of the size <br />of the shaft, details of construction of the head frame, and /or the hoist house, and how the <br />power will be supplied. The reclamation plan and reclamation bond will need to address details <br />and costs for removal of the head frame and other mine infrastructure. <br />(12)The reclamation plan refers to vent hole reclamation but does not address reclamation of the <br />access roads or power lines to the structures. Please submit reclamation plans for all access <br />roads and power lines to be reclaimed. <br />(13) The last paragraph of Page E -1 that carries over to E -2 notes the "material depth to be removed <br />will be determined in the field during reclamation effort, based on a gamma survey ". The <br />Division needs to know what the gamma readings are prior to disturbance, or currently, to <br />establish baseline levels. A baseline radiometric survey is required for all proposed affected <br />surface areas that could potentially be contaminated with radioactive materials such as waste <br />rock, ore, radioactive dust, radioactive water, etc. to establish current on site conditions and will <br />be part of the EPP. <br />
