the reasonable sources, probable fate, and transport mechanisms of metal and acid - producing <br />minerals that may be mobilized during development and reclamation of the Cresson Project. <br />Using all the hydrologic and geochemical information developed for the District, an evaluation <br />was conducted of the fate and transport of water infiltrating to the subsurface through all mines, <br />mine backfill, and OSAs created by MLE2. The results of the analysis were verified by checking <br />against the observed behavior of the hydraulics and chemistry of the diatreme since Cresson <br />Project surface mining began in 1993, using the measured vertical hydraulic gradients in and <br />near the diatreme, and the flow rate and chemistry of the regional ground water exiting the <br />Carlton Tunnel portal. The results of the analysis indicate that no deleterious change in the <br />average regional ground water quality from the District will occur due to current or proposed <br />operations of the Cresson Project. <br />14.15 Construction Schedule Information <br />New facilities proposed as part of MLE2 that will contain or use designated chemicals include <br />the SGVLF, SGADR, and the High Grade Mill facilities. The existing AGVLF and AGADR <br />facilities will continue to contain or use designated chemicals with no new construction planned <br />for these facilities. The anticipated construction schedule for the SGVLF, SGADR, and High <br />Grade Mill facilities is shown on Table 5 -1 and discussed in Sections 7.2.2, 8.0, and 6.3, <br />respectively, of this Project Description. Construction of the SGVLF is anticipated be begin in <br />2012 and will take approximately four to five construction seasons to complete both Phase 1 and <br />Phase 2. The High Grade Mill facilities are anticipated to be constructed during the period 2012 <br />through 2014. The actual construction schedule will depend on various factors, with weather <br />conditions during the construction season being an important consideration. <br />14.16 Quality Assurance and Quality Control <br />Construction QA/QC are an integral part of the construction plans. New construction will be <br />conducted with QA/QC comparable to that has been implemented for the entire Cresson Project. <br />The QA/QC for the construction of the SGVLF is discussed in Section 7.3 of the Project <br />Description. In addition, Appendix 9, Volume V of this document contains Technical <br />Specifications that include QA/QC requirements. <br />14.17 Plant Growth Medium <br />A soil survey report is discussed in Section 4.8 of this Project Description and included as <br />Appendix 3, Volume III of this document. Appendix 3 includes a soils map.
