04PZ and cadmium and nickel at SGMW -3B were above the analytical detection limits, <br />but low. Trace metal data also are provided in Tables 5 -6 and 5 -8. <br />5.2.4.4 MLE2 Impacts to Ground Waters <br />The SGVLF construction and operation in the middle reaches of the Squaw Gulch <br />drainage (Figure 2 -2) will cover approximately 346 acres with impermeable liner. The <br />capture of precipitation by the SGVLF will limit infiltration of precipitation to, and <br />saturation of the shallow alluvium in the middle reaches of the Squaw Gulch drainage. <br />The drainage of ground water in the shallow alluvium in the middle and lower reaches of <br />Squaw Gulch into the granite bedrock and into the Diatreme will continue after <br />construction of the SGVLF. Water quality conditions in the shallow alluvium and <br />bedrock after the construction of the SGVLF are expected to be similar to the current <br />conditions in the near -term. The selective removal or stabilization of historic mine <br />facilities in the middle reaches of Squaw Gulch during SGVLF development is likely to <br />improve the ground water quality in the long -term. <br />As noted above, ground water monitor stations SGMW -3A, SGMW -3B, and SG -04PZ <br />will be lost by the construction of the SGVLF. The water level and water quality <br />conditions in the granite bedrock adjacent to the Diatreme will continue to be monitored <br />by SGMW -5. <br />5.3 Gold Run Gulch <br />5.3.1 Current Conditions <br />The Gold Run drainage and MLE permit boundary are shown on Figure 2 -1. Gold Run is <br />a southwest oriented dry drainage. The Gold Run drainage intersects Cripple Creek <br />approximately 6,000 feet southwest of where SH 67 crosses the drainage. <br />The current Cresson Project disturbance in the Gold Run drainage consists of the <br />AGVLF. The limits of the AGVLF are shown on Figure 2 -1. The existing EMPs that <br />collect and dissipate storm water runoff are shown on Figure 2 -1. <br />The boundary between the Diatreme and the surrounding granites in the Gold Run <br />drainage is shown on Figure 2 -2. <br />'Cripple Creek & Victor Gold Mining Company <br />Cresson Project Hydrologic Evaluation for Mine Life Extension 2 <br />20 <br />
