Letter to Bryce Romig -4- November 6, 1995 <br /> four quarterly samples. This proposed procedure is not acceptable under <br /> the terms of Rule 3. 1.7 (9) of the Mineral Rules and Regulations. Please <br /> commit to providing a written report within five (5) working Idays when <br /> there is evidence of ground water discharges exceeding applica le ground <br /> water standards or permit conditions for any of the point of ompliance <br /> monitoring wells established at the Climax Mine. <br /> In addition to the point of compliance to be established for GWM #2, the <br /> Division proposes that GWM #1 also be made a point of compliance. The <br /> rational for the Division's proposal is as follows: (1) GWM #1 data <br /> indicate that shallow ground water at the location of the well is being <br /> impacted by tailing disposal and/or process water handling in the Tenmile <br /> Creek Valley; (2) at least a component of the impacted ground is <br /> discharged to the creek at a point up-gradient from GWM #2; (3) the <br /> Mineral Rules and Regulations require that where ambient ground water <br /> quality exceeds values for protection of existing and reasonably potential <br /> future uses of ground water, permit conditions shall be established to <br /> protect those uses against further lowering of ground water quality (Rule <br /> 3.1.7 (2) (c) (ii) ) . The Division proposes that a statistical analysis be <br /> completed on the existing GWM #1 data, and that numeric protection levels <br /> be established for Mo and for those constituents that exceed receiving <br /> stream standards based on the ambient quality so determined, and that <br /> numeric protection levels for constituents that do not exceed stream <br /> standards be established at the level of the stream standards. The same <br /> list of parameters would be analyzed at GWM #1 as is discussed for GWM #2 <br /> above. <br /> The Division further proposes that a ground water monitoring well be <br /> established in the Minturn Formation below the Mayflower treatment plant. <br /> If ground water entrained or flowing in the Minturn Formation has been <br /> impacted by tailing disposal and/or process water handling in the Tenmile <br /> Creek Valley, then permit conditions would have to be established to <br /> protect existing and future beneficial uses of that ground water. A <br /> monitoring well in the Minturn Formation will facilitate determination of <br /> ambient ground water quality so that permit conditions can be established. <br /> Please provide a proposal for installation and monitoring of such a well. <br /> Arkansas River Valley <br /> The Division concurs with your proposal to continue analysis and reporting <br /> of samples from the AMW monitoring well. In addition, and as discussed <br /> previously in this letter, a deep bedrock well will need to be established <br /> west of the Mosquito Fault in order to evaluate the protection afforded <br /> ground water quality by the presence and postulated impermeability of the <br /> fault. Please provide a proposal for installation and monitoring of such <br /> a well. <br /> Eagle River Valley <br /> It is stated in the "Ground Water Quality" section of the technical <br />
