COLORADO <br /> Division of Water Resources AVs <br /> Department of Natural Resources <br /> 1313 Sherman St., Room 821 <br /> Denver', CO 80203 <br /> Response to Notice of 112c Construction Materials Reclamation Permit Partial Acreage <br /> Release Request Consideration <br /> To: Stephanie J. Environmental Protection Specialist <br /> From: s ina P. Mickelson, Physical Science Researcher/Scientist <br /> Date: December 28, 2017 y ­1W <br /> Re: Permit No. M-1980-022-AR01 'Ole <br /> Operator: Oldcastle SW Group, Inc. dba United Companies of Mesa County ; <br /> Preston Pit Extensions�pN <br /> Section 16, Twp 1 S, Rng 1 W, 6th P.M.; Mesa Countyll /�y�RFC �SgFN <br /> CONDITIONS FOR APPROVAL AND <br /> Well permit no. 37604-F was issued on August 27, 1991 for construction and operation of the Preston Pit <br /> Extension. The average annual amount of ground water diverted shall not exceed 169 acre-feet with a <br /> total surface pond area of 33 acres. The use of ground water in addition to evaporation is limited to <br /> dewatering of the pit area and the extraction of aggregate materials. <br /> Currently this location is not considered overappropriated, however, if this area becomes <br /> overappropriated, the evaporation and other consumptive use from the gravel pit well will be subject to <br /> administration. It is recommended that a water court decree be obtained to affirm the priority of the uses <br /> of groundwater from the gravel pit well. <br /> If storm water is not diverted or captured in priority, Colorado Water Law requires it to be released, or <br /> replacement for evaporation will be required of the impounder/operator/owner of the gravel pit. The State <br /> Engineer's current policy requires that all impounded water be released to the stream system within a <br /> maximum of 72 hours after impoundment. Unless captured in priority, impounded water may not be used <br /> for any purpose except as approved under a water supply plan or decreed plan for augmentation. <br /> COMMENTS: <br /> This office has no objections to the Notice of 112c Construction Materials Reclamation Permit Partial <br /> Acreage Release Request so long as the site operates under a valid well permit for any ground water <br /> exposure or use. <br /> The applicant may contact the State Engineer's Office with any questions. <br /> Cc Division 5 Engineer <br /> District 72 Water Commissioner <br /> �p <br /> 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866,3581 �� y <br /> John W.
