8.0 EXHIBIT G—WATER INFORMATION <br /> 8.1 Introduction <br /> The combined Holton-Morton Lakes Sand and Gravel Pit lies in parts of the SE1/4 of <br /> Section 1 and the NE 1/4 of Section 12, Township 1 North, Range 67 West, and Parts of the S W <br /> 1/4 of Section 6 and the NW 1/4 of Section 7 Township 1 North, Range 66 West of the 6th P.M., <br /> Weld County, Colorado. The site is approximately a mile west of Fort Lupton, immediately <br /> south of Colorado State Highway 52, and west of Colorado State Highway 85. <br /> The mining operation will be on either side of the South Platte River. It will affect the <br /> South Platte River in the form of groundwater depletions due to evaporation and water uses <br /> associated with mining. The impacts to the South Platte River have been mitigated without <br /> injury to the vested senior water rights. Mining at the Morton-Holton Lakes site will last <br /> approximately 15 years. <br /> Morton Lakes (Permit M-2008-082)is being mined in conjunction with Holton Lakes to <br /> the east(Permit M-2007-008). The Morton-Holton Lakes reclamation plan will create four slurry <br /> wall sealed excavations that will not be hydraulically connected to the South Platte River alluvial <br /> aquifer. The mining plan will also create four unlined excavations (Stages 1, 2, 3 and 9 acres in <br /> the northeast corner of Stage 6 that total 62 acres. Stages 1 and 2 will be backfilled with wash <br /> fines from the sand and gravel processing plant and Stages 3 and 9 acres of 6 will be backfilled <br /> with overburden. The remaining four mining stages(4, 5, 6, and 7)will each be sealed prior to <br /> mining. The combined lined storage on both of Morton-Holton Lakes will be approximately 253 <br /> acres for an estimated volume of 7500 acre-feet. <br /> A substitute water supply plan(SWSP)pursuant to C.R.S. 37-90-137, has been approved <br /> by the State Engineer's Office (SEO) for replacement of depletions associated with the Morton- <br /> Holton Lakes sand and gravel mining operation. See section 8.6 of this Exhibit G. <br /> 8.2 Potential Water Resource Impacts <br /> Ground Water Wells <br /> The Morton Lakes Pit will have minimal impacts on the prevailing hydrologic balance. <br /> Sand and gravel mining related impacts to ground water wells near the Pit will be mitigated <br /> through the installation of slurry walls around the perimeter of stages 4, 5, 6 and 7 prior to <br /> 12 <br />
