MLE disturbance in Poverty Gulch consists of the North Cresson Mine area. <br />Development of the North Cresson Mine area will continue through 2016 under <br />Amendment No. 8 and MLE approvals. The limits of the mine area are shown on Figure <br />2 -1. The existing EMPs that collect and dissipate storm water runoff are shown on <br />Figure 2 -1. <br />5.1.2 Mine Life Extension 2 <br />MLE2 does not propose to construct any new facilities in the Poverty Gulch drainage. <br />The North Cresson Mine area will expand slightly to the northwest side and on the <br />southwest side and continue operation through 2025. The North Cresson Mine area will <br />be backfilled during MLE2. The EMPs will continue in MLE2. The disturbance limits <br />and the proposed facilities for MLE2 across the Cresson Project are shown on Figure 2 -2. <br />MLE2 will not impact any of the existing monitor stations in the Poverty Gulch drainage. <br />5.1.3 Surface Water <br />5.1.3.1 Monitoring Program <br />There are no surface water resources in Poverty Gulch. <br />5.1.3.2 Data <br />There are no surface water data for Poverty Gulch. <br />5.1.3.3 Discussion <br />There are no surface water resources in Poverty Gulch. <br />5.1.4 Ground Water <br />5.1.4.1 Monitoring Program <br />Ground water conditions in Poverty Gulch are assessed by a one monitor well (Figure 2- <br />2). The monitor well is designated PGMW -2 and is completed in the Diatreme. <br />Field parameters and water quality samples are collected quarterly at PGMW -2 and <br />analyzed for the parameters listed in Table 3 -2. <br />5.1.4.2 Data <br />Figure 5 -1 shows the water level measurements. Table 5 -1 shows the water level data. <br />Due to the dry conditions in the well, no water quality data are available. <br />'Cripple Creek & Victor Gold Mining Company <br />Cresson Project Hydrologic Evaluation for Mine Life Extension 2 <br />14 <br />
