Operational water requirements have included <br /> gravel washing , equipment washing, and dust control . <br /> The source of water for these operational requirements_ <br /> has historically been a combination of municipal water ob- <br /> tained from the City of Greeley, drainage water seeping <br /> into the gravel pit which would otherwise evaporate, and a <br /> well on the site with Permit. Number 6065-R. The scope of _ - <br /> the gravel operation is not expected to be enlarged in the <br /> ■ future over what it has historically been. Consequently <br /> l(�T there is no anticipation that either gross water requirements <br /> ' or depletion of. the- local water supplies will be increased as <br /> a result of the proposed mining plan. <br /> L' Pit Dewatering <br /> _ The mining operation proposed by R.V. Lord and Associates <br /> L envisions the extraction of gravel from a sequence of pits <br /> of several acres in extent. Overburden material would first <br /> be removed, and the gravel mined to the ground water level. <br /> When the water level is reached an interceptor trench " <br /> ' will be constructed around the pit in order to divert the ground <br /> water flowing into the pit and lower the ground water level <br /> 1 <br /> -2- <br />
