<br />:1 <br />i <br />'} <br />.J <br /> <br />Conceptual Request for Proposals <br /> <br />~ <br /> <br />· Project life - The project life is used in the amortization of the <br />project's capital costs and cost-effectiveness computation, Overly <br />optimistic estimates of project life bias the cost-effectiveness <br />cdmputation. The life expectancy of new technologies are generally <br />l\) le:Ss reliable than older, "time-tested" technologies. Also, some <br />c.n tEichnologies tend to have more risk than others, Deep well injection <br />W h.s a relatively high risk due to the uncertainties involved in <br />i-> estimating the well's receiving capacity and life, Pipelines tend to be <br />m'ore'reliable than open ditches that are exposed to the local <br />weather. <br /> <br />. Operation and maintenance (O&M) - Some proposals may be <br />more or less susceptible to poor O&M practices. To minimize this <br />riilk factor, sponsors may propose "robust" solutions that require <br />relatively little maintenance, For example, buried irrigation laterals <br />relIuire little attention, while open concrete ditches are more prone to <br />weathering and require annual maintenance to remain fully effective. <br /> <br />The ranking team will consider the risk that the program's capital <br />inl<estments may be lost from poor maintenance. In the past, <br />~clamation has provided supplemental, annual O&M funding to <br />mjUntain certain projects. Reclamation has found this difficult to <br />fund and administer, If essential to the continued performance of <br />the project, the program will consider (or may require) funding an <br />O,$.M trust to cost share the maintenance of capital improvements <br />and safeguard the program's investment, If funded by the program, <br />this cost would be included in the proposal's cost-effectiveness <br />computation. <br /> <br />· Mtmagement - Generally, projects that rely on a high degree of <br />management to maintain their efficiency will be downgraded unless <br />thlire is reason to believe it is sustainable, Highly automated <br />sY$tems that are simple to operate will reduce this risk, For <br />example, automatic sprinkler shutoffs would improve management <br />risk. <br /> <br /> <br />· M~asurable or verifiable results - Projects for which the salt load <br />rec;luction can be independently verified add a degree of certainty to <br />tM proposaL For example, interception of saline springs is a highly <br />verifiable method (both water volume and concentration can be <br />dh!ectly measured), Irrigation delivery system improvements are <br />som.ewhat more difficult to measure, but shallow monitoring wells <br />next to the lined canal can confirm the absence of seepage, and <br />dr~inwater can be used to measure concentration, Onfarm deep <br />percolation reductions may vary significantly from farm-to-farm and <br />year-to-year, Statistical sampling may be required, <br /> <br />C-13 <br /> <br /> <br />, , <br />
