Section 816.100 Continued. <br />• overburden will be utilized to bring these areas to grade and <br />reestablish effective drainage. Given Kerr Coal's decision not to <br />proceed with development of the Pit 2 and 3 areas, the northern portion <br />of Pit 1 was backsloped to establish maximum 3.O:1V slopes and provide <br />effective drainage. Backsloping resulted in disturbance of <br />approximately 10.0 acres along the pit margins and provided <br />approximately 800.000 BCY of spoil material for final pit reclamation. <br />Supplemental backfill placement in the Pit 1 reclaim area will result in <br />temporary redisturbance of approximately 12 acres in the two previously <br />disturbed designated borrow areas. <br />In sequencing backfilling activities for Pit 1 and the 720 Pit, Kerr <br />Coal has identified and considered the following significant objectives: <br />1. Reclamation of all existing disturbance in a timely, logical <br />manner <br />2. Maximizing the effectiveness of short term reclamation <br />activities while preserving the opportunity for development of <br />further reserves if market conditions warrant. <br />Given these objectives, Kerr Coal backfilled the southern and central <br />portions of Pit 1 as remaining Pit 1 reserves were mined. The southern <br />and central portions of Pit 1 were subsequently backfilled and regraded <br />in 1993 and early 1994. <br />Simultaneously with production and backfilling of Pit 1. Kerr Coal <br />continued backfilling the 720 Pit from the existing overburden <br />stockpile. Kerr Coal initially dozed approximately 350,000 BCY from the <br />west edge of the overburden stockpile into the 720 Pit. During the <br />following 2.0 to 2.5 years, backfilling operations focused on movement <br />of <br />,657\VOL.3\SECTION.676 816.124a Revised - 01/30/95 <br />!26!95 9:12em WP51/cme <br />
