Mr. Brock Bowles <br />March 27, 2017 <br />Page 2 <br />2.04.11(4) and 2.05.6(2), please update T&E species and discuss potential impacts to current State <br />and Federal Threatened and Endangered plant and animal species lists. The Federal and State listed <br />species of concern may have changed since the last revision or the issuance of permit. <br />Response: The last T&E species list update provided by the CPW in March 2015 should be adequate <br />to cover the current bonded area south of Meehan Draw. Therefore, no additional updates should be <br />required during the permit term proposed by this renewal application. If future disturbance north of <br />Meehan Draw is anticipated, CPW will be consulted to update the T&E species list. <br />Section 2.05.4(2)(b) — Reclamation Cost Estimate <br />1. The current reclamation cost estimate and bond covers the 202.9 acres disturbed south of Meehan <br />Draw. The area north of Meehan Draw was permitted but not bonded because it was not proposed to <br />be disturbed during the initial 5 -year permit term. The next 5 -year permit term (with the approval of <br />RN -01) will include disturbances in the area north of Meehan Draw as shown on Map 2.05.2-1. The <br />Division is in the process of creating a RCE with separate line items for the area north of Meehan <br />Draw and will submit it to Tri-State for comment when it is complete. <br />Response: ERMR wishes to maintain the area north of Meehan Draw as permitted but not bonded <br />items. If future disturbance is anticipated, adequate bond v<ill be posted for these items prior to <br />disturbance. <br />2. The equipment corridor is a permitted and bonded item that was approved for disturbance to move <br />mining equipment from NH2 to NHN at permit issuance. The corridor was inspected last summer and <br />no disturbances were noted indicating that the corridor has not been utilized. Does ERMR want to <br />maintain the equipment corridor as a permitted and bonded item? <br />Response: ERMR wishes to maintain the equipment corridor as a permitted but not a bonded item. If <br />future disturbance is anticipated, adequate bond will be posted for this item prior to disturbance. <br />Section 2.05.6(3) — Mitigation of the Impacts of Mining Operations <br />1. It is not clear if point of compliance wells been established and identified. Groundwater monitoring <br />wells GW -N56, GW -N57 and GW -N58 were previously anticipated to become the points of <br />compliance wells, but it is not clear if or at what point this will occur. Please clarify the identification <br />of the point of compliance wells. <br />Response: Point of compliance wells have yet to be established or identified for the New Horizon <br />North Mine, Permit #C-2010-089. This item will be addressed outside of this renewal application in a <br />future technical revision application. <br />Section 2.05.6(3)(b)(v) —Hydrological Reclamation Plan <br />1. On page 3, paragraph 4 of the Surface Water Quality section has been removed from the submitted <br />pages. Please clarify why this paragraph was removed or state its new location. <br />Response: Surface water control for NHN includes routing all runoff through deigned and approved <br />sediment control structures and collection ditches. Temporary diversions utilized at NHN consist of <br />structures internal to the mining area. Since the runoff collected by these temporary diversions <br />ultimately pass through designed and approved sediment control structures, no designs or approvals <br />are needed. Therefore, the portion of the Surface Water Quality section addressing temporary <br />diversions has been removed from the submitted pages. <br />AN EQUAL OPPORTUNITY / AFFIRMATIVE ACTION EMPLOYER <br />A Touchstone Energy' Cooperative -t . <br />
