<br /> <br /> <br /> <br />PR-04, Colowyo Coal Mine C1981-019 39 August 2016 <br /> <br />the Collom pit, and completed in the Trout Creek Sandstone (see Stipulation 18). The well will <br />be monitored quarterly for water level and field water quality parameters, and annually for a full <br />suite of laboratory parameters. <br /> <br />A future spoil water monitoring well will be drilled into the reclaimed Collom pit, at the lowest <br />point, in order to monitor and measure the potential development of a spoil aquifer. <br /> <br /> <br />H. Transfer of Wells - Rule 4.05.14 <br /> <br />No transfer of wells is proposed. All monitoring wells will be reclaimed prior to bond release. <br /> <br />I. Water Rights and Replacement - Rule 4.05.15 <br /> <br />CCC has demonstrated that no owner of a vested water right is proximately injured. <br /> <br />J. Discharge of Water into an Underground Mine - Rule 4.05-16 <br /> <br />No surface water will be discharged into underground mine workings. <br /> <br />K. Stream Buffer Zones - Rule 4.05.18 <br /> <br />With PR-03, the Division approved surface mining activities through several creeks that are large <br />enough (drainage area greater than one square mile) to require buffer zones or approved <br />exceptions per Rule 4.05.18. This is based on a finding that the original stream channels will be <br />restored, water quality and quantity will not be adversely affected, and appropriate riparian <br />vegetation will be reestablished, as necessary. <br /> <br />A large section of Little Collom Gulch will be directly impacted by the pit, spoil pile, and <br />Section 25 Pond. To protect the section of this creek below mining, CCC has committed to build <br />and maintain clean water diversions and the Section 25 Pond. After mining, CCC has committed <br />to reestablish the profile and function of Little Collom Gulch. <br /> <br />The Division also approved haul road crossings of Wilson Creek and Jubb Creek. At these <br />crossings, CCC will employ BMPs and will perform any necessary reclamation as soon as <br />practicable. <br /> <br />L. Probable Hydrologic Consequences <br /> <br />Based on an assessment of drainages in the Collom area and the fact that all runoff from the mine <br />area is to be either diverted around the mine or retained in sedimentation ponds, no significant
