Nettleton, Jerry <br />To: Justin.pollack @state.co.us <br />jim. haskins @state.co. us <br />bject: FW: Twentymile Coal, LLC - TRO Coal Quality Coreholes - Wildlife Consultation Letter <br />Attachments: DrillSiteLocationMapWC _Overview_20140206.pdf; MR14 -275 WCR Coal Coreholes III <br />TL.doc <br />Justin — <br />We are requesting your assistance in reviewing information and providing a wildlife consultation letter to support the <br />associated permit applications for a project we plan to complete this winter: <br />Wolf Creek Reserve (WCR) Coal Corehole Project (Sections 17 and 21, T5N, R86W) —We plan to complete up to <br />four additional coal coreholes (WC011 through WC014) to characterize the Wolf Creek Coal Seam and collect <br />the necessary geologic information for permitting. The planned coreholes have been located adjacent to or in <br />close proximity to existing mine /ranch roads to minimize access requirements and disturbance. Each corehole <br />would require a 75' x 75' drill pad, with minor disturbance for access where the coreholes are not immediately <br />adjacent to existing roads. Appropriate drainage and sediment control measures would be used to control <br />runoff and sediment from pad areas. On completion of coring and logging each hole, coreholes would be <br />plugged and sealed consistent with State Engineer requirements, and drill -pad and any temporary road access <br />disturbance would be reclaimed. Work would be initiated as soon as all required permit approvals are received, <br />and would be completed during the winter (ie: prior to grouse mating season in mid - March). If all site <br />reclamation work is not completed by mid - March, sites would be stabilized, and reclamation would be <br />completed after the grouse nesting season (ie: after July 15) <br />ached for your reference are a map showing the proposed activities, and descriptive text. A permit application has <br />ueen submitted to the Colorado Division of Reclamation, Mining, and Safety (CDRMS), and we have indicated that we <br />will forward the wildlife consultation letter on receipt. <br />We appreciate your cooperation and assistance. Please feel free to contact me with any questions, or to discuss — <br />Best regards, <br />Jerry <br />Jerry M.
