All mined material to be disposed of onsite will be disposed in a manner to prevent <br />contamination of the surface drainage system, as per Rule 3.1.5(10). <br />Pollutants are not expected to be released to groundwater during reclamation. <br />5.3.5 Water — General Requirements <br />Disturbances to surface water and groundwater will meet all applicable Colorado water laws and <br />regulations. Necessary permits will be obtained for wells and disturbances. All Colorado and <br />federal water quality standards will be met both on the statewide level, and on a site - specific <br />standard basis. Any variation will be reclaimed to mitigate water contamination. <br />No siltation structures lay in drainways at the Greeley 35Th Avenue Mine. <br />No earth dams will be constructed on the Greeley 35`h Avenue Mine as a part of reclamation. <br />The land surface of the Greeley 35`h Avenue Mine will be stabilized as necessary to control <br />erosion. <br />5.3.6 Groundwater— Specific Requirements <br />Groundwater quality standards will be maintained during reclamation operations. Deviations <br />from regulated water quality standards as a result of mining operations at Greeley 35`h Avenue <br />will be reclaimed in an expedient and appropriate manner. <br />Greeley 35`h Avenue Mine has no areas classified by the Water Quality Control Commission <br />(WQCC) to be monitored for groundwater quality. Mining and reclamation activities in areas not <br />classified by the WQCC will be carried out in such a manner to protect groundwater resources <br />outlined by the WQCC. <br />Groundwater disturbance and interaction is anticipated to be minimal. Measures will be taken to <br />preserve existing groundwater resources as reclamation commences. Points of compliance and <br />groundwater sampling may see monitoring plans on the Greeley 35`h Avenue Mine property and <br />hydrologically downstream as appropriate and required by the Board. <br />MODFlow models and analyses have been utilized to demonstrate the estimated effect of <br />reclamation on existing groundwater resources. Models were created to estimate the effect of a <br />slurry wall keyed approximately 5 feet into bedrock in the West Pit on the Greeley 35`h Avenue <br />property. MODFlow results are available in Attachment C. <br />Wildlife <br />Wildlife reclamation measures have not changed from the Greeley 35`h Avenue Mine permit, M- <br />1977 -036. <br />
