• groundwater data. Two of the four existing wells completed in the Wadge Coal, and two <br />of the four existing wells completed in the Wadge overburden will be selected for <br />collecting baseline data from both formations. However, because the wells have been in <br />place for more than twenty years, more information is needed from each well to <br />determine if the wells remain properly sealed and will provide adequate water level and <br />quality data for baseline purposes. <br />No new alluvial wells are proposed at this time. An existing Seneca Coal Company <br />(SCC) alluvial well at the Seneca H Mine located below the portal location to be finalized <br />prior to the onset of baseline monitoring activities will be utilized for collecting baseline <br />alluvial groundwater data (e.g., SCAL46 located below the southern proposed portal <br />location). <br />Surface Water Site Installations <br />No new surface water monitoring site installations are proposed for baseline monitoring <br />purposes. Existing SCC surface water site established downstream of the proposed portal <br />location will be utilized for collecting baseline surface water data. <br />Groundwater Baseline Data <br />It is anticipated the WUB wells at exploration holes ccu013 and ccu014 will be <br />• completed by mid -July, and the WUB, WC, and WOV wells at exploration hole ccu025 <br />may not be completed until late September 2008. Water levels will be collected monthly <br />in each new WOV, WUB and WC monitoring well after completion, weather permitting <br />during the winter and spring depending on access. Water quality samples will be <br />collected from each new WOV, WUB and WC monitoring well soon after completion, <br />and attempts will be made to collect quarterly water samples from the wells through <br />2009, weather permitting. <br />Beginning in June 2008 through August 2008, water levels will be collected monthly <br />from all eight existing monitoring wells, and water samples will be collected from all <br />eight existing wells in June and August 2008. This data will be evaluated as soon as <br />available to select two of the four existing WC wells and two of the four existing WOV <br />wells for collecting baseline data. At a minimum, monthly water levels and quarterly <br />water samples will be collected from two existing WC and two existing WOV wells <br />through 2009, weather permitting. <br />Water quality sampling will be targeted soon after completing each new monitoring well, <br />or during the months of June, August, and October for the existing monitoring wells. <br />Attempts will be made to collect water quality samples from the new and existing <br />monitoring wells during the first quarter 2009, weather permitting. Field water quality <br />parameters (pH, EC, and temperature) will be collected concurrently, and samples will be <br />analyzed using ACZ Laboratories in Steamboat Springs, Colorado. Samples collected for <br />baseline purposes in new and existing monitoring wells will be analyzed for the attached <br />• Ground Water Quality Parameter List, which includes the suggested suite of parameters <br />2 <br />
