M1980-183. The purpose of this amendment is alleviate ground water mounding at <br />the connection point between Pit 29 and the Stagecoach Stop Pit (M1983-067) by the <br />installation of a French drain along the south portion of the north cell of Pit 29 and along the <br />northern portion of the Stagecoach Stop Pit. The AM -02 previously contemplated the <br />installation of a French drain on the upgradient (south) side of Pit 29. The site was then <br />amended to a location north on the Pit 29 property. The amendment now seeks a new route <br />that will take the drain northward along the west side of Pit 29 then under Brighton Road. <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 wet[) will be in place for more than one year after construction. Upon <br />completion of the ground water mitigation, the operator must plug the French drain in <br />accordance with Rule 16 of the Water Well Construction Rules. <br />The applicant may contact the State Engineer's Office with any questions. <br />1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3585 www. water. state. co. us I <br />
