.. <br />map showing the location of all registered domestic, irrigation, or other wells within 600 feet of <br />the affected land and pumping rate from such wells, if significant <br />water quality data collected from any domestic wells within 600 feet of the affected land or <br />within the known existing contaminant plumes as defined by the Tri County Health <br />Department and Colorado Waste Management & Hazardous Materials Division <br />20. Please provide all available information regarding the current status of the depth, shape, <br />direction of travel, and rate of movement of any contaminant plumes within the affected land or <br />surrounding area (aquifer). Known contaminants as presented by Pinnacle Pines, LLC are <br />"DIMP"; several organic compounds including methylene chloride and other chlorinated volatile <br />organic compounds; pesticides including parathion, DDT's, malathion, and atrazine; and non- <br />chlorinated hydrocarbons including ethylbenzene and zylene. The Division recotrtmends that you <br />contact Tri-County Health Department, Colorado Hazardous Materials & Waste Management <br />Division, Colorado Water Quality Control Division, and Pinnacle Pines, LLC for information on <br />these contaminants as well as any other regulated contaminants that may be present. <br />21. Please provide the appropriate State water quality standards for the various contaminants <br />listed above in hem 20. <br />22. The applicant has provided a reclamation plan which specifies creation of a 40 acre lined <br />water storage reservoir. Given the water quality concerns expressed by several objectors and <br />defined by Pinnacle Pines, LLC ,please describe the desired uses of the water storage reservoir <br />and the corresponding water quality standazds necessary for the waters to be contained within the <br />reservoir, ie: agricultural water use, municipal water use, drinking water use, etc. <br />23. Based on available information and water quality data please provide an analysis of the <br />presence of any soils and/or groundwater contaminants within the affected land and/or the <br />potential for future contamination of soils and/or groundwater during mining and reclamation. <br />Such analysis should include an assessment of the cone of depression and inflows expected <br />during dewatering and pumping and how the applicant intends to verify that the permeability of <br />the reservoir liner will be sufficient to exclude any neazby contaminant plumes such that the <br />stated waters will meet the appropriate State water quality standards as defined in Item 22 above. <br />Further, the analysis should also define the potential for existing or future contamination within <br />the 13.2 acre wetland. <br />24. Please indicate the status of the NPDES Water Discharge Permit that will be required from <br />the Water Quality Control Division for planned discharges from the site, given the potential for <br />existing or future groundwater contaminants. <br />25. Other review comments from Dr. Harry Posey will be forwarded to the applicant as soon as <br />they are available. , <br />
