<br />RE: Moffat County Mining, LLC. — Williams Fork Mines (Permit C-81-044),2013 Annual Reclamation
<br />Report (ARR)
<br />Dear Mr. Ebert:
<br />Enclosed are duplicate copies of the 2013 Annual Reclamation Report for the Williams Fork Mines (formerly Eagle
<br />5 & 9 Mines). During the first part of 2013, this property was considered to be in "active reclamation" due to
<br />recent (2011 -2012) reclamation activities, however in May 2013, Moffat County Mining, LLC (MCM) submitted a
<br />request and supporting documentation to place the property in "Temporary Cessation" status (TR13 -35). The
<br />CDRMS approved this request in July 2013. Under the Temporary Cessation status, no new disturbance or
<br />reclamation occurred during 2013, and site activities were limited to ongoing site maintenance, monitoring, and
<br />required inspections.
<br />During 2006, the frequency of surface and ground water monitoring was increased to provide updated hydrologic
<br />information, in the event that Peabody Energy (MCM's parent company) decided to pursue further exploration and
<br />feasibility evaluations for the Williams Fork property, and the more intensive hydrologic monitoring continued
<br />during 2007- through 2012. During 2007, there was an oil pipeline rupture, which resulted in a localized oil spill on
<br />the southern portion of the Mine property (outside of Mine Permit Area). Peabody Environmental Staff
<br />coordinated with the pipeline operator (Rocky Mountain Pipeline) on containment, clean -up, and remediation.
<br />Inspection of the affected area during 2008 indicated effective removal of oil contamination, restoration of effective
<br />drainage (several intermediate catch basins were removed, but final catch basin remains in- place), placement of
<br />imported soil materials, and initial vegetative reestablishment. Visual inspection of this area indicates effective
<br />vegetative establishment.
<br />MCM's predecessor, BTU Empire Company, LLC (BTUEC), completed final reclamation grading, drainage
<br />reestablishment, soil material replacement, and revegetation seeding of approximately 17.1 acres, encompassing the
<br />No. 9 Portal Area and adjacent Refuse Disposal Area, in May 2009. Reclaimed areas were reseeded with the
<br />approved seed mixture that fall, and areas are inspected several times each year for any erosion or sediment
<br />transport concerns, invasive noxious weeds, and vegetative reestablishment.
<br />MCM contracted and completed field repair and stabilization of the eroded streambank in the abutment areas of the
<br />railroad bridge over the Williams Fork River during 2011. Minor repair of erosion and rodent holes was also
<br />completed for the Pond 5D embankments and the on the Access Road to the Mine No. 5A/6 Portals and water -bars
<br />were installed on the old highway between the 7 -North Angle Well and the Mine 516 Portals. It was noted that the
<br />siphon -tube under the Williams Fork River for the Worthington Ditch was exposed and damaged during the
<br />previous year's high spring flows. MCM reviewed options for transmission of flows in this Ditch, however, related
<br />repair and maintenance work has been deferred. During 2011 -2012, MCM also completed testing and removal of
<br />petroleum products, emulsion fluids, and other chemicals and chemicals wastes from the Shop /Warehouse, Multi -
<br />Services Building, and exterior storage tanks, and completed EPA compliant closure of the tanks, all using a
<br />licensed waste contractor.
