Nutrient Criteria: Current Status for the Central States, TMDL Development and New Tools forNutrient Reduction EvaluationBrandon KoltzSymbiontIllinois, Wisconsin and Minnesota either have or will be implementing criteria for phosphorus and /ornitrogen. Each state either has or is imposing some point source controls through technology standards.TMDLs are ongoing with respect to attainment of nutrient or nutrient related impairments in all threestates.USEPA has recently made available a web based tool to examine nutrient characteristics in watershedsand at specific locations. USGS has developed an interactive website that utilizes the SPARROW(SPAtially Referenced Regressions On Watershed attributes) to predict the nutrient loading fromwatershed units and the subsequent transport downstream. The model has been applied the Mississippiand Great Lakes watersheds as well as watersheds in the northwest, the east coas, and southeast. Theweb application may be used to examine the effect on instream nutrient transport and water qualitycaused by a reduction in nutrient loading from different watershed hydrologic units. In this way, theonline tool is intended as a decision-making tool to assess the efficacy of different source reductionpossibilities.This presentation will provide:A brief overview of status instream nutrient criteria and technology standard development.An example of a discharge permit incorporating water quality based phosphorus discharge limitsfrom WisconsinPotential effect of a TMDL on point source dischargersIllustration of the USEPA’s online water quality monitoring toolIllustration of the online SPARROW phosphorus and nitrogen watershed transport modelA requirement for nutrient reductions will affect many dischargers in the coming years. Knowledge ofpotential requirements and use of available planning tools will assist dischargers in understanding theeffect of their discharge on the receiving stream and downstream receptors, and participate inwatershed planning efforts in an informed manner.
