r~ ' Block 10 ' The erosion condition composite SSF score for this area was 6, which placed it in the Stable erosion class. The tabulated results for this survey are shown in Table 11. The area was ' seeded in late 1996. Several gullies connecting to the final pit drainage channel existed in the block. The gullies originally resulted from late summer storm activity in 1997. The gullies were repaired and seeded in 1998. No corrective measures are planned as a result of the inventory.

West Ridge has been ' separated into nine different blocks for the Erosion Inventory Control Report using the terraces as boundaries (see Exhibit 1, Sheet 2). Table 12 provides a summary of the inventory data and is followed by a brief description of each block and corrective measures performed on each block ' as a result of previous inventories. P&M personnel expect that some erosional features may develop in the newly reclaimed areas for the next several years until vegetation begins to establish. The terraces are performing as anticipated; existing gullies located primarily on older non-topsoiled reclamation show no sign of activity and seem to be stabilizing with vegetation establishing along the sides and bottoms. Most blocks showed slight improvements over the previous year. The reduced status was primarily caused by the slow establishment of vegetation ' on the most recently reclaimed non-topsoiled portions of the blocks. The winter of 2003-2004 was very mild with low precipitation and little runoff. In addition, June 2004 was wetter than ' usual with precipitation coming in low intensity storms. This permitted 2002 repairs to establish vegetation and vegetation in stable rills and gullies to become better established. During the 2004 survey, several gullies were identified for repair. These gullies were generally associated with overtopping of the terraces. As a result of this survey, Terraces T5, T7, T10, and T11 will be repaired. In addition, gullies in Blocks 1-6, 6-7, 8-9, 10-11, and 11-12 will be repaired in 2004. ' 9
