Peabo 1111 ENERGY Moffat County Mining, LLC 29515 Routt County Road #27 Oak Creek, CO 80467 970.879.3800 Ms. Tabetha Lynch Environmental Protection Specialist Division of Reclamation, Mining, and Safety 1313 Sherman Street - Room 215 Denver, Colorado 80203 (303) 866-3567 X8147 RECEIVED FEB O"52018 Division of Reclamation, Mining & Safety January 29, 2018 RE: Moffat County Mining, LLC. — Williams Fork Mines (Permit C-81-044),2017 Annual Reclamation Report (ARR) Dear Ms. Lynch: Enclosed are duplicate copies of the 2017 Annual Reclamation Report for the Williams Fork Mines (formerly Eagle 5 & 9 Mines). In May 2013, Moffat County Mining, LLC (MCM) submitted a request and supporting documentation to place the property in "Temporary Cessation" status (TR13-35). The CDRMS approved this request in July 2013. Under the Temporary Cessation status, no new disturbance or reclamation occurred during the period 2013 through 2016, and site activities were limited to ongoing site maintenance, monitoring under a reduced schedule, and required quarterly inspections. In November 2016, MCM notified the CDRMS of plans to initiate site reclamation activities, and the change in property status from Temporary Cessation to Active Reclamation. Permitting Activity During 2014 and 2015, the only permitting actions that occurred were finalization and approval of the Permit Renewal (RN13-06, approved 10/15) and an associated Technical Revision (TR14-36) addressing the PAP revisions associated with both the renewal and outstanding items from the Permit Mid -Term Review, and several Minor Revisions (MR15-51/52/53/54) providing updated ownership and control information, and documentation on a non -mining clean-up of a historic dump area within the mine Permit Boundary. These revisions did not result in any change to the Permit, affected, or disturbed area figures, however, recalculation and updates to the bond reclamation estimate resulted in increases in the total calculated reclamation liability. MCM provided a bond rider addressing this change in early 2015. During 2016, MCM submitted and obtained approval (01/04/17) of Technical Revision TR16-37, modifying the revegetation success sampling methods and success standards. The only additional permitting activity occurring during 2017 was submittal of a Surety Reduction Request on March 14, 2017, with final approval on May 15, 2017. Site Activities During 2007, there was an oil pipeline rupture, which resulted in a localized oil spill on the southern portion of the Mine property (outside of Mine Permit Area). Peabody Environmental Staff coordinated with the pipeline operator (Rocky Mountain Pipeline) on containment, clean-up, and remediation. Inspection of the affected area during 2008 indicated effective removal of oil contamination, restoration of effective drainage (several intermediate catch basins were removed, but final catch basin remains in-place), placement of imported soil materials, and initial vegetative reestablishment. Visual inspection of this area indicates effective vegetative establishment. During 2013-2014, the current owner of the oil pipeline, Plains All American Pipeline, completed maintenance and repair to several sections of the existing pipeline, with all activities occurring within their dedicated easement. Maintenance and repair activities included trenching and replacement of a section of the pipeline in the vicinity of the previous pipeline rupture, and inspection and repair/replacement of a section of the pipeline paralleling the Old Highway.
