<br />WATER QUALITY IMPLEMENTATION STRATEGY <br />SURFACE WATER !YiANAGEMENT <br />NONPOLNT SOURCE POLLUTION TO ALL METROPOLITAN WATERS <br /> <br />SUnlmary of The Poticy Issue <br /> <br />In 1990 lhe U.S. Environmcnlal Protection Agency (EPA) and the Minnesota Pollution Control <br />Agency (MPCA) agreed on a goal to rcduce non point source pollution in the Minnesota River by <br />40 percent [rom pre-1980 level.>. The lwo agencies have set 1996 as the lurget date to uchieve this <br />goal. To accomplish this gaol, current land development ~nd agricultural practices must be altered <br />to restrict nonpoint source pollutants from entering ~re~ water Ixldies. While the Minnesota River <br />may be ~n acute case o[wntcr quality dcgradation due to nonpoint source pollution all woter bo<.Iies <br />in the seven county area are impacted to some degree by human activities in Ixlth urban and rural <br />areas. <br /> <br />The Mississippi 'River, "especially in the Spring Lake and Lake Pepill area, is severally impacted by <br />excessive algal growth. A major inter-stale and federal study is currently being conducted to identify <br />the causes of the excessive algal growth. However, it is known that nutnenl<, nitrogen and <br />phosphofm, from whatever Sourc~ are the prime cau~e of exces.sive algal growth. Both the State of <br />Wisconsin and the U.S. Environmental Protection Agency are attempting to get the MPCA to impose <br />phosphorus limits On the Metropolitan Plant in St:, Paul as a means to reduce the algal growth. If <br />phosphorus limits ~re imposed on the Metropolitan Plant this could result in c~pit<ll expenditures of <br />$80 to 360 million. Sincc phosphorus is found in surface water runoff it may be more cost effective <br />to control nonpoint SOurceS' of runoff and have ~ more bene[icial impact On the river than by <br />controlling point sources of phosphorus. <br /> <br />To address the acute problems on the Minnesota River, the Council developed an interim strategy <br />for' communities in the Minnesota River basin. This strategy incorporated basic water quality <br />management practice.; that will improve the water quality of the area water bodies. During the public <br />participation process in developing these strategies, it became clear that these same i"nterim ~tra[egics <br />were appropriate for all local governments in the seven county area. A consistent and equitab"Ie <br />policy is established to apply these strategies metro-wide. <br /> <br />The Problem <br /> <br />The. Metropolitan Council has documented an increase of nonpoint .~ource pollution to arca water <br />bodies. These added pollutants reduce the recrealional valuc and acceleratc the eutrophication of <br />area water bodies. The increase of non point source pollutants to area water bodies can be traced <br />to twO primary sources: land development and agriculture practices.. ,und development or <br />urbaniutioa, generally increases both the volume of runoff as well as the eoncentration of pollutants <br />in the runoIT. This happens with the conversion of land to hard surfaces and by the destruction of <br />wetlands. DClcfltioo ponds or artificial depressions can help mitigate these impacts. The best <br />designed ponds, however, will not rcduce the increased volume of runoff fol1owing urbanization oor <br />will they totally remove the additional pollutants following urbanization. An incre:>sc in runoff <br />volume, lotal phosphorus and other pollutafl!s are thc results of urban development. <br /> <br />I <br /> <br />~ <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />II <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />.. <br />I <br />
