Use this information,. <br />along with watershed condition and other soil and water <br />resource data, to develop improved design of management <br />practices, provide a comparison of outputs under alterna- <br />tive management practices, and establish a basis for use in <br />defining water resource management objectives. The analysis <br />must be rigorous enough to make definitive statements con- <br />cerning anticipated water quality response. Apply a risk <br />analysis to selected alternatives similar to that discussed <br />in Chapter 10, FSH 2509.15. <br /> <br />2532.3 - Water Quality Standards. Each State is required <br />to review its water quality standards at least once every <br />3 years and revise them as necessary. Participate in <br />review of State standards and work toward change where <br />consideration is not given to the following factors: <br /> <br />1. Standards should reflect national as well as local <br />water quality objectives; be related to beneficial uses, <br />and recognize natural background and variability. <br /> <br />2. Compliance with approved best management practices <br />for control of nonpoint sources should constitute compliance <br />with water quality standards and these practices should be <br />based upon site-specific conditions and should include a <br />consideration of political, social, economic, and technical <br />feasibility. <br /> <br />3. Water quality standards that reflect nonpoint source <br />conditions should be used to measure effectiveness of best <br />management practices. <br /> <br />4. Consideration should be given to evaluating certain <br />water quality concerns, such as sediment, by observing a <br />surrogate such as channel condition. <br /> <br />s. Antidegradation policy should include a considera- <br />tion of both time and space and should not be based on <br />change at a single point. <br /> <br />. <br /> <br />*-FSM 2/86 AMEND 47-* <br /> <br />e <br /> <br />e <br /> <br />e <br /> <br />e <br /> <br />e <br />
