Peabo <br />1111 ENERGY <br />Moffat County Mining, LLC <br />29515 Routt County Road #27 <br />Oak Creek, CO 80467 <br />970.879.3800 <br />Ms. Robin Reilley <br />Environmental Protection Specialist <br />Division of Reclamation, Mining, and Safety <br />1313 Sherman Street - Room 215 <br />Denver, Colorado 80203 <br />(303) 866-3567 X8105 <br />RECEIVED <br />FEB 15 2019 <br />DIVISION OF REGLA�MTION February 11, 2019 <br />MINING AND SAFETY <br />RE: Moffat County Mining, LLC. — Williams Fork Mines (Permit C-81-044), 2018 Annual Reclamation <br />Report (ARR) <br />Dear Ms. Reilley: <br />Enclosed are duplicate copies of the 2018 Annual Reclamation Report for the Williams Fork Mines (formerly Eagle <br />5 & 9 Mines). In May 2013, Moffat County Mining, LLC (MCM) submitted a request and supporting <br />documentation to place the property in "Temporary Cessation" status (TR13-35). The CDRMS approved this <br />request in July 2013. Under the Temporary Cessation status, no new disturbance or reclamation occurred during <br />the period 2013 through 2016, and site activities were limited to ongoing site maintenance, monitoring under a <br />reduced schedule, and required quarterly inspections. In November 2016, MCM notified the CDRMS of plans to <br />initiate site reclamation activities, and the change in property status from Temporary Cessation to Active <br />Reclamation. <br />Permitting Activity <br />During 2014 and 2015, the only permitting actions that occurred were finalization and approval of the Permit <br />Renewal (RN13-06, approved 10/15) and an associated Technical Revision (TR14-36) addressing the PAP <br />revisions associated with both the renewal and outstanding items from the Permit Mid -Term Review, and several <br />Minor Revisions (MR15-51/52/53/54) providing updated ownership and control information, and documentation on <br />a non -mining clean-up of a historic dump area within the mine Permit Boundary. These revisions did not result in <br />any change to the Permit, affected, or disturbed area figures, however, recalculation and updates to the bond <br />reclamation estimate resulted in increases in the total calculated reclamation liability. MCM provided a bond rider <br />addressing this change in early 2015. During 2016, MCM submitted and obtained approval (01/04/17) of Technical <br />Revision TR16-37, modifying the revegetation success sampling methods and success standards. During 2017 a <br />Surety Reduction Request was submitted on March 14, 2017, with final approval on May 15, 2017. As part of <br />ongoing site reclamation and clean-up efforts, MR18-56 (approved 01/29/18) facilitated loading and transport of <br />remaining coal from the coal storage stockpile area to the Foidel Creek Mine. In addition, the renewal application <br />(RN18-07) for the CDRMS Mining and Reclamation Permit was submitted on February 9, 2018 and approved on <br />November 8, 2018. Recalculation of the reclamation liability, as part of the renewal process, resulted in an increase <br />in the calculated liability amount of approximately $92,447, which was addressed by a bond rider submitted and <br />approved by the CDRMS in December 2018. <br />Site Activities <br />During 2007, there was an oil pipeline rupture, which resulted in a localized oil spill on the southern portion of the <br />Mine property (outside of Mine Permit Area). Peabody Environmental Staff coordinated with the pipeline operator <br />(Rocky Mountain Pipeline) on containment, clean-up, and remediation. Inspection of the affected area during 2008 <br />indicated effective removal of oil contamination, restoration of effective drainage (several intermediate catch basins <br />were removed, but final catch basin remains in-place), placement of imported soil materials, and initial vegetative <br />
