Barrett " <br />] RE: EXHIBIT "G" MINED LAND RECLAMATION BOARD PIT PERMIT APPLICATION, UiJA PIT <br />I).4TF.: Eebraury 28, 1980 <br />As required for Exhibit "G" on the Mined Land~Reclamation Board Pit <br />Permit application, I have reviewed the prwposed excavation and its <br />' impact on ground and surface waters. <br />The pit is located in the floodplain of the Colorado River, and a pond <br />will be created by the excavation. Based on Blaney-Griddle calculations, <br />loss of water due to evaporation from the lake surfacing will be approximately <br />equal to phreatophyte evapotranspiration currently occurring from the <br />existing vegetative cover. <br />No significant impact on ground or surface waters is expected due to this <br />operation. <br />/, ~ ~.~ <br />RKB/clc 0 ERT K: BARR T <br />cc: file DISTRICT III GEOLOGIST <br />
