Please refer to the enclosed comment letter from the Division of Water Resources, Office <br />of the State Engineer (SEO) dated October 28, 2010. The SEO has identified several <br />concerns with the proposed project as summarized below. <br />• If the area becomes overappropriated, the storage of surface water in sediment <br />ponds would be subject to administration. The SEO recommends that a water court <br />decree be obtained to affirm the priority of the storage of storm water. <br />• If any of the sediment ponds expose groundwater, the pond must be backfilled <br />immediately until a well permit issued pursuant to CRS 37- 90- 137(2), allowing the <br />exposure of groundwater in a pit is obtained from the State Engineer. <br />• The SEO has no records of permits for the existing monitoring wells on site. As <br />stated in the SEO's letter, if these wells were completed without a valid monitoring <br />hole notice or well permit the applicant needs to take immediate action to plug or <br />permit the wells. <br />• Last, the SEO notes that the applicant states that portions of the site may affect <br />current surface water diversions. If at any point the applicant's operations will <br />affect surface diversions they should consult with the local water commissioner to <br />assure no injury to water rights occur. <br />Please address each of these concerns and provide a response and amended application <br />materials, if appropriate. <br />CAM Response: Based on the new hydrology design, using BMP's instead of relying <br />solely on sediment ponds, the first two concerns of the SEO are no longer applicable for <br />
