�57 3 <br />irrigated cropland. The use of PAM will also achieve this effect. <br />This will reduce sediment on the lower portions of the fields and into <br />the Arkansas River. No cost sharing is available through PL -566 for ' <br />conservation tillage or crop residue use. <br />Irrigation water utilization will be improved by changing water <br />irrigation methods and procedures. This is a non -cost share practice , <br />through PL -566. <br />Wetland mitigation practices anticipated will include approximately 10 I <br />multi - purpose ponds and 20 Acres of wetland development. <br />Improved Surface Systems - about 26,700 acres will have present surface , <br />irrigation systems improved. An estimated 1/2 of the acres will be <br />converted to surge irrigation. Improvements include land leveling, <br />plastic pipe, ditch lining gated pipe, and related practices. Land <br />leveling will improve irrigation water application and reduce deep <br />percolation. Plastic pipe will be installed to deliver water to surge <br />valves, and also to gated pipe in fields proposed for shorter lengths <br />of run. Total estimated cost of improved surface irrigating systems is ' <br />$1,834,300 for federal share and the same for the local share. <br />Mitigation I <br />Where wetlands are impacted by installation of conservation measures, <br />mitigation will be carried out in accordance with Natural Resource ' <br />Conservation Service Policy. This policy states that where mitigation <br />is needed, it will replace wetlands on a value for value basis. Any <br />needed mitigation will be required to be included in participants <br />contracts. Other mitigation arrangements will be considered as options ' <br />become available. <br />Permits and Compliance I <br />It is the contractees responsibility to obtain any federal permits or <br />formal land rights that will be needed to install the project (40 CFR , <br />1502.25). In the event that land rights or permits become necessary, <br />the responsibility to acquire these items will occur before <br />construction. <br />Costs <br />The total cost of <br />the project <br />which includes both federal and local <br />money is $5,326,000. <br />Table 1 <br />itemizes the costs by measure. Those <br />measures showing <br />no cost will <br />not be cost - shared under this project. <br />Table 1 displays <br />federal and local <br />how the costs <br />dollars. <br />of each measure are shared between <br />The federal cost -share rate is 50 percent for enduring irrigation <br />practices. The federal Cost -share rate for other enduring practices is <br />based on the rate presently used by other federal programs for similar <br />practices.
