<br />. <br /> <br />. <br /> <br />. <br /> <br />The group then collectively tried to identify what modifications in the current classification and standards <br />system to reflect these features: <br /> <br />. More protective classifications and standards needed for effluent dominated streams, <br />. Standards should recognize differences in flow (time, segment) <br />. Standards should recognize hydrologic modifications: <br />o Water management may preclude certain uses as some times; <br />o Water management may create other uses, <br />. System needs flexibility to respond to natural disasters. <br />. System should recognize source water variability. <br />. System should recognize variability in water bodies, <br />. System should recognize effluent dependence <br />o Nutrients are necessary for the habitat <br />. Refined aquatic life uses: <br />o Is the aquatic life the same as that used in criteria development or has it evolved and adapted <br />to chemical and physical habitat? <br />. Net environmental benefit: loss of discharge=>loss of aquatic ecosystem, <br />. Modified system should not lose the concept of future potential uses, <br />. System should recognize that diversions are sometimes 100% consumptive. <br />· Federal actions concerning the ESA must connect with CW A and standards setting process III <br />Colorado. <br />. Should antidegradation apply to secondary drinking water standards? <br />. Should antidegradation apply to effluent dependent and dominated streams? <br />. Should anti degradation apply to streams dominated by ag return flows? <br />. Should reuse require different standards for groundwater recharge? <br />. System should recognize that operation of constructed water conveyances have uses that should be <br />protected, <br /> <br />Al!ricuIture Use <br /> <br />There was a discussion of the two agriculture uses: (1) crop irrigation; and (2) livestock watering. It was <br />suggested that a discussion of the agriculture uses might be more meaningful if someone from the CSU <br />Extension Service provided a short presentation on water quality issues for agriculture, Arrangements will be <br />made for such a presentation at the Group's November meeting if possible. <br /> <br />The group submitted thoughts on the need, or lack thereof, for refined agricultural uses. See the attached <br />sunJrnary of Post-It Comments. <br /> <br />Drinkinl! Water Supolv Use <br /> <br />The Advisory Group discussed the existing drinking water supply use and various issues raised during recent <br />Water Quality Control Commission hearings. Comments were collected, See the attached summary of Post-It <br />Comments, <br /> <br />46 <br />
