ditch is not exceeded by the addition of dewatering water. The McCanne Ditch <br />will determine whether and how it is entitled to take credit for this water under <br />Colorado's priority system. <br />Currently, surface runoff from Petrocco's property is collected in a drainage <br />ditch on the east side of Brighton Road and is transported under the road to a ditch <br />along the south side of the Arends property. Water is carried in this ditch to the <br />southwest corner of the Arends property, at which point it is dispersed on to the <br />hillside above the McCanne Ditch. A portion of the dispersed water reaches the <br />McCann Ditch. Prior to the start of mining, RMCC will improve and line with <br />bentonite the ditch along the south side of the Arends property and construct an <br />extension of the ditch (also bentonite lined) on the east side of North Tower Lake <br />to carry Petrocco's surface irrigation return flow water directly to the McCann <br />Ditch. <br />B. Mitigation during Reclamation <br />During reclamation, RMCC will install a French Drain system along the west <br />side of Brighton Road. This drain will be installed between the compacted <br />backfill and the mining setback along Brighton Road. The French Drain will serve <br />to protect property and structures east of the backfilled pit from ground water <br />mounding. The ground water intercepted by the French Drain will be discharged <br />directly to the McCann Ditch. Also, because of the gradient of the ground water <br />table towards the South Platte River, ground water not intercepted by the French <br />Drain system will naturally migrate around the compacted backfill area to the <br />McCann Ditch. <br />RMCC will also construct a bentonite lined ditch from the west side of <br />Brighton Road at East 144 Ave. to the relocated section of the McCann Ditch. <br />This ditch will replace an existing ditch on the Reinoehl property, which <br />conveyed irrigation runoff and dispersed it in an open area on the west side of the <br />Reinoehl property up-gradient from the McCann Ditch. Unlike the existing <br />ditch, the new ditch will discharge water directly into the McCann so that the <br />McCann may receive a greater amount of water from the new ditch than it did <br />under historic conditions. <br />III. Summary <br />Implementation of RMCC's proposed mitigation plan both during mining and <br />as part of reclamation for the protection of the McCann Ditch will ensure that the <br />proposed mining and reclamation plan will have no adverse effects on the <br />operation of the ditch. <br />8/26/2009
