These actions may include <br />consultations, advice, engineering, and other technical assistance <br />that land users usually cannot accomplish by themselves. Nonproject <br />treatment and/or financial assistance may result in the land user's <br />installing field terraces, waterways, field leveling, onfarrn <br />drainage systems, farm ponds, pasture management, conservation <br />tillage, critical area stabilization, and other conservation <br />practices. <br /> <br />r,~. <br /> <br />NPDES - National Pollutant Discharge Elimination System <br /> <br />Onfarm Irrigation Efficiency - Ratio of water consumed by crops on <br />irrigated land to the amount of water delivered at the farm <br />headgates supplying that land. <br /> <br />Part Per Million (PPM) - One part by weight of dissolved chemical, or <br />suspended sediment, in one million parts by weight of water. <br /> <br />" <br /> <br />Percolation - The downward movement of water through soil, especially <br />the downward flow of water in saturated or nearly saturated soil. <br /> <br />Perennial Stream - A stream that flows continuously throughout the year. <br /> <br />Permeability - The quality of a soil horizon that enables water to move <br />through it. <br /> <br />,~' <br /> <br />';, <br /> <br />Phreatophyte - A plant deriving its water from subsurface sources; <br />commonly used to describe nonbeneficial water-loving vegetation. <br />As defined in this report it includes plants such as saltbush, <br />greasewood, cottonwood trees, sagebrush, and native nonirrigated <br />grasses along canals, laterals, wasteways, drainage ditches, and <br />next to the river systems. <br /> <br />,..~t' <br /> <br />>;~ <br /> <br />Project Costs - A term commonly used in connection with water resource <br />development projects.

The Principles provide the broad <br />framework for planning activities and include the conceptual basis <br />for planning. The Standards provide for uniformity and consistency <br />in comparing, measuring, and judging beneficial and adverse effects <br />of alternative plans. <br /> <br />G-5 <br /> <br />C:.!11t;9 <br />
