<br />' Ken Coa! Compa~ry 1991 Annna! Hydrology Report ~ 1 <br />1.0 OPERATIONAL CONDITIONS <br />Mining and reclamation activities at the Kerr Mine and Loadout continued during <br />the 1991 water year at a capacity less than designed and permitted. Coal <br />production for 1991 resulted in the removal of approximately 62,400 tons, which <br />is slightly over 7% of the permitted capacity. This is a result of continuing poor <br />` market conditions. As in 1990, mining activities were confined to the Pit 1 area <br />and no additional areas were disturbed. Approximately 364,500 BCY were <br />excavated from the northend of Pit 1 and backfilled into the south end of Pit 1. <br />Approximately 440,100 CCY were removed from the existing overburden <br />stockpile and placed in the backfill in the 720 Pit. No new areas were backfilled <br />to the permitted postmining topography during the year, therefore no final <br />grading, topsoiling or final reclamation was conducted. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />M <br />ACZ lnr. • P.O.
