2. Hydrologic Monitorin4 <br />A. Surface Water - HG Coal Company continues to monitor four <br />surface water locations. The locations include two sites <br />near the loadout on Dry Creek and two sites near the <br />reclaimed mine and shop area on Hayden Gulch. All <br />locations are sampled on a semi-annual basis. <br />Water analysis data from both Upper and Lower Dry Creek <br />indicate no problems with water quality parameters. <br />Likewise, water analysis data from both Upper and Lower <br />Hayden Gulch indicate no problems with water quality <br />parameters. Due to dry conditions at Upper Hayden Gulch, <br />no flow was recorded at this sampling site in the fall. <br />Analysis for the surface water monitoring locations on <br />Dry Creek and Hayden Gulch are presented in Exhibits 1 <br />and 2. <br />B. Groundwater - HG Coal Company continued groundwater <br />monitoring at the reclaimed minesite, reclaimed shop <br />area, and the loadout area. <br />The HG-2 well is monitored down dip of the reclaimed <br />• minesite for quality and water level. No significant <br />changes in water quality were noticed during 1992. <br />The HG-1 well is monitored down dip of the reclaimed shop <br />area for water quality and level. Results of analysis of <br />samples taken during 1991 indicate no problems with water <br />quality parameters. <br />The UC-2 well is monitored for water depth. No changes <br />have occurred. <br />water quality at the loadout area is monitored by an up- <br />dip alluvial well which represents undisturbed conditions <br />and a down-dip alluvial well which represents disturbed <br />conditions from the loadout operation. No impacts are <br />evident since the water quality at the down-dip well is <br />generally better than the up-dip well. <br />Analysis for the groundwater monitoring at the minesite <br />and shop are found in Exhibit 4 and analysis for the <br />groundwater monitoring at the loadout are found in <br />Exhibit 3. <br />2 <br />
