JD -6 Mine Environmental Protection Plan 51 <br />11. CONSTRUCTION SCHEDULE <br />Rule 6.4.21(15) requires that the Operator submit construction schedule information for all Environmental <br />Protection Facilities designed to contain or transport toxic or acid - forming materials or designated <br />chemicals used in the extractive metallurgical process and all facilities proposed to contain, hold, or dispose <br />of material that has the potential to cause acid mine drainage. The construction schedule for Environmental <br />Protection Facilities at the JD -6 Mine is provided in Table 28. <br />Item <br />Site Diversion Drainage <br />Stormwater BMPs <br />Line existing stormwater Line catchment with low - permeability liner September 2013, Pending <br />catchment to reduce /eliminate infiltration DRMS approval <br />Monitoring Well Install monitoring well on JD -6 DOE lease <br />Sealing of mine portal <br />Sealing of vent shaft <br />Decommissioning of fuel <br />storage area <br />Final reclamation <br />Notes.

QUALITY ASSURANCE / QUALITY CONTROL <br />Rule 6.4.21(16) asks for a description of the Quality Assurance and Quality Control program and measures <br />to be employed during construction of the Environmental Protection Facilities discussed in Rule 6.4.21(15). <br />The quality control for construction of stormwater BMPs will include the submission of as -built <br />engineering drawings ( "As- Builts "). The As- Builts will be provided within 90 days after the stormwater <br />facilities are constructed and will be certified (signed and stamped). <br />Geochemical sampling will be conducted on ore and waste rock (run -of -mine) during active mining. At <br />least one sample of waste rock and one sample of ore from the JD -6 Mine will be analyzed for geochemical <br />characterization (whole rock, ABA, and SPLP) for every 50,000 tons of waste rock produced, or yearly, <br />whichever occurs more frequently during active mining operations only. <br />4148A.120927 Whetstone Associates <br />
