O'Donnell, Environmental Protection Specialist <br />CC: Division 1 Office, District 2 Water Commissioner <br />FROM: loana Comaniciu, P.E. <br />RE: Pit 29, Permit No. M1080 -183 <br />Operator: Brannan Sand and Gravel <br />Contact: Brannan Sand and Gravel - 303 - 534 -1231 <br />Section 35, Twp 1 South, Rng 67 West, 6th P.M., Adams County <br />CONDITIONS FOR APPROVAL <br />Brannan Sand and Gravel requested an amendment to the application for Pit 29, Permit no. <br />M1980 -183. The purpose of this amendment is to mitigate ground water mounding on the <br />Einspahr property located immediately to the south of the north cell of Pit 29. The plan has <br />been designed to reestablish the ground water levels that existed prior to mining. A French <br />drain is proposed to be installed on the upgradient (south) side of Pit 29 at the Einspahr <br />property. The French drain will begin in the northeast corner of the Einspahr property, <br />continue down gradient west to a maintenance manhole at the northwest corner of the <br />Einspahr property, than continue approximately 1200 feet along the west side of Pit 29. The <br />beginning and ending elevations of the drain will coincide with the estimated pre - mining <br />water levels. <br />Prior to the construction of the French drain the operator is required to submit to the State <br />Engineer's Office a Notice of Intent to Construct a Dewatering Well (Form GWS -62). All <br />ground water pumped from the French drain (dewatering well) shall not be used for any <br />beneficial purposes and must be discharge to the stream system without consumptive use, <br />including evaporation losses. The operator will need to obtain a well permit if the French <br />drain (dewatering well) will be in place for more than one year after construction. Upon <br />completion of the ground water mitigation on the Einspahr property, the operator must <br />plugged the French drain in accordance with Rule 16 of the Water Well Construction Rules. <br />The applicant may contact the State Engineer's Office with any questions. <br />C °LOS <br />1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3585 www.water.state.cc.us <br />', * � Vic. • a <br />1876 <br />
