5.1.4.3 Discussion <br />PGMW -2 has shown dry conditions in the monitor well since installation in 2005. <br />The dry conditions in PGMW -2 suggest that the bedrock ground water is captured by the <br />Diatreme at this location. A comprehensive analysis of the horizontal and vertical ground <br />water flow and ground water gradients in the Diatreme and the adjacent granites for the <br />Cresson Project area, and specifically Grassy Valley is presented in "Cresson Project <br />Hydrogeochemical Evaluation" dated February 2012 and prepared by ABC. <br />5.1.4.4 MLE2 Impacts to Ground Waters <br />No impacts are anticipated to the ground water resources in the Poverty Gulch due to <br />MLE2. <br />The water level and water quality conditions in the Diatreme bedrock will continue to be <br />monitored by PGMW -2. <br />5.2 Squaw Gulch <br />5.2.1 Current Conditions <br />The Squaw Gulch drainage and MLE permit boundary are shown on Figure 2 -1. Squaw <br />Gulch is a southwest - oriented, ephemeral drainage that crosses the Diatreme - granite <br />boundary. Squaw Gulch drains into Cripple Creek approximately 4,700 feet southwest of <br />where SH 67 crosses the drainage. Historical mine features within the Squaw Gulch <br />drainage include: historical and residual waste rock stored behind the Mary McKinney <br />cribbing; spoils piles from old glory holes and adits located above SH 67, historical mill <br />tailings deposited in Squaw Gulch below SH 67, and historic town sites of Anaconda and <br />Mound City. <br />The current MLE disturbance in the Squaw Gulch drainage consists of the SGOSA and <br />exploration - related activities (e.g., roads, pads, etc.). The SGOSA construction started in <br />1993. Rock placement in the SGOSA will continue through approximately 2016 under <br />MLE. The current and final limits of the SGOSA and the SGOSA extension are shown <br />on Figure 2 -1. The existing EMPs that collect and dissipate storm water runoff are <br />shown on Figure 2 -1. <br />The boundary between the Diatreme and the surrounding granites passes through the <br />Squaw Gulch drainage and is shown on Figure 2 -2. <br />'Cripple Creek & Victor Gold Mining Company <br />Cresson Project Hydrologic Evaluation for Mine Life Extension 2 <br />15 <br />
