Aurora Water ILI City of Aurora <br /> . , <br /> Water Resources 7 p lt4�rltrlJi�cvnrrin� • aruv»u,Suv.r» <br /> 15151 E. Alameda Parkway, Ste. 3600 GRUB <br /> Aurora, Colorado 80012 <br /> 303.739.7370 <br /> July 31, 2015 <br /> Mr. Eric Scott <br /> Environmental Protection Specialist <br /> Colorado Div. of Reclamation,Mining and Safety <br /> 1313 Sherman Street, Room 215 <br /> Denver, Colorado 80203 <br /> RE: Letter in Support of ASCI Request to Negate Requirement for Monitoring Wells, Chavers Mining <br /> Resource,DRMS Permit No. M-2015-030 <br /> Dear Mr. Scott: <br /> Asphalt Specialties Co., Inc. ("ASCI") has asked the City of Aurora to provide a letter regarding the need for up- <br /> gradient groundwater monitoring wells associated with their application for a sand and gravel mining site(Chavers <br /> Mining Resource) west of US-85 and north of WCR-8 adjacent to the South Platte River. It is our understanding <br /> that DRMS has made it a requirement that as part of the approval for this site that they install/commit to install <br /> groundwater monitoring wells outside of the proposed slurry wall surrounding the mining area. <br /> The City of Aurora owns the approximately 30-acre parcel directly to the south and adjacent to the proposed <br /> mining site along the entire east-west length. Aurora plans to develop this property for additional alluvial <br /> groundwater production wells adjacent to the river for additional water production and conveyance as part of it's <br /> Prairie Waters water supply system for the city.The two abandoned homes and outbuildings of the site will shortly <br /> be demolished and removed. Currently,Aurora has no other planned facilities on the site other than the wells and <br /> related infrastructure. There are oil and gas facilities on site and the operator may install additional facilities in the <br /> future. <br /> At this time, we do not believe that a slurry wall at the proposed location will have negative groundwater impacts <br /> to Aurora's interest in the property to the south and do not believe that groundwater monitoring will be necessary. <br /> In summary, we support the efforts by ASCI to negate the requirement for up-gradient groundwater monitoring <br /> wells as they would appear to have no viable purpose for monitoring groundwater levels up-gradient of the slurry <br /> wall. <br /> While we support ASCI in this matter, this letter does not constitute a waiver of our right to take part or comment <br /> in the permit process as it proceeds. In addition, Aurora cannot speak for the oil and gas operator onsite. <br /> If you have any further questions or concerns, please feel free to contact me directly at (303) 739-7326 and thank <br /> you for your attention to this matter. <br /> Sincerely, <br /> Richard Vidmar, P.E. <br /> Senior Water Resources Engineer <br />
