Worksheet 00d: No change. <br />Worksheet 00e: As a result of the Phase II release, several tasks for topsoil <br />redistribution have been eliminated (reduction of $917,966.00). However, because TR- <br />57 greatly increased the subsoil and topsoil replacement depth, costs to redistribute <br />subsoil and topsoil on the prime farmland areas have increased. The previously <br />approved replacement depth was 22", the weighted average replacement depth for the <br />area is now 58.8". This resulted in a $846,808.00 increase with TR-57. The attached <br />table depicts the increase or decrease for each individual topsoil redistribution task. <br />Total direct cost decrease amount: $71,158.00. <br />Worksheet 00f: Hourly operating costs for a D9N-U have decreased; costs for replacing <br />topsoil on Pond 013 have been removed from this worksheet, since that area is <br />included in Task 30f. Total direct cost decrease amount: $4,449.00. <br />Worksheet 00g: Revegetation costs are reduced with removal of the costs for <br />anticipated failure on the 304 acres approved for Phase II release. Total direct cost <br />reduction amount: $7,859.00 <br />Worksheet 00h: Hourly operating costs for a D9N-U have decreased. Total direct cost <br />reduction amount: $545.00. <br />Worksheet 00i: Irrigation costs are decreased slightly as a result of updated cost <br />information; mobilization of the grader for site maintenance is slightly lower, assuming <br />this piece of equipment would be mobilized from Nucla rather than Grand Junction. <br />Total direct cost decrease amount: $37,558.00. <br />For the Phase 11 Bond Release request (SL-11), 1 would recommend that we propose a <br />release of only liability (no money) on the six release areas, since the required surety <br />amount after the release ($5,042,302.00) exceeds the amount we currently hold <br />($4,000,000.00). <br />For the renewal application (RN-05), we should show an increase in required surety of <br />$1,891,739.00. The current required surety is $3,150,563.00; the new required surety is <br />$5,042,302.00, so WFC will need to increase their self bond amount by a minimum of <br />$1,042,302.00. <br />I realize this is a somewhat convoluted approach, but hope that I have made it clear. <br />Should you or the operator have questions or need additional information, please let me <br />know. <br />cc: Sandy Brown, Mout enclosure <br />2
