measurements by SCC began in August 1994. These sells were abandoned with bentanite <br />pellets on July 16, prior to the construction of pond 012. • <br />- Lennox Coal. Txo sell s, YLS and 6, monitor the Lennoz coal seam in the Saga Creek <br />basin. Both wells are flowing antl are fitted with pressure gages. pressure measurements <br />by SCC began in August 1994. These wells were abandoned with bantonite pellets on July <br />16, prior to the construction of Pond 012. <br />- Wadqe Overburden. Seven wells; YOV1, 9, 15, 19, 28, 29 and 30; monitor the Wadga <br />overburden. Wall YOV28 exists in the Armand Draw basin, all others exist in the gaga <br />Creek basin. Most walla exhibit typical seasonal fluctuations, and rater levels this year <br />within their historic ranges, although soma lag time for the spring rechazge is observed. <br />Well YOV1 ras abandoned with bentoni to pellets on July 16, prior to the cone traction of <br />Pond 012. Well YOV2B (downgradient of the current mine pit) has experienced a decrease in <br />water levels since August 1996. Well YOV30 to+a also experienced a decline in rater <br />levels, although it is in a premining area (Sage Creek basin). <br />- Wedge Coal. Seven rolls; YW2, 7, 14, 18, 28, 29, and 30; monitor the coal seam. Well <br />YW28 exists in the AMand Draw basin, all others exist in the Sage Creek basin. Due to <br />the for aquifer tcanemissivi ties, seasonal rater level fluctuations are much lees <br />pronounced than the alluvium and overburden, and are often masked by rater sampling <br />effects. Moat walla exhibited rater levels this yeaz within their hie torie ranges. Wall <br />Yci2 ras abandoned with bantonite pellets on July 16, prior to the construction of pond <br />012. Well YW28 (dorngradient of the currant mine pit) has experianced decreasing rater <br />levels since October 1996. In the Sage Creek basin, rater levala at well YW29 aze <br />increasing, chile rater levala at cell YK30 are decreasing. <br />- Wedge Underbuzden. Five rolls; YWU16, 17, 28, 29, and 30; monitor the wedge <br />underburden. Well YWU28 exists in the Armand Draw basin, all others exist in the Sage <br />Creak basin. Most of these cells do not exhibit any significant seasonal variation, <br />although some vaziation from yaaz-to-year i9 evident. Most wells exhlbited rater Lavela <br />this yeaz within their historic ranges. well YWU28 (downgradient of the current mina pit) <br />han ezperienced decreasing rater lave la from June 1996 to September 1997, but has recently <br />ezperienced a rise in water levels. In the Saqe Creek basin, cells YWU29 and 30 have also <br />experienced increasing rater levels. <br />• <br />4 <br />
