MPCA GENERAL CONSTRUCTION PERMIT — General Permit Authorization <br />to Discharge Stormwater Associated With Construction Activity Under the National <br />Pollutant Discharge Elimination System/State Disposal System Permit Program <br />Permit MN R100001 (NPDES General Construction Permit) issued by the Minnesota <br />Pollutant Control Agency, August 1, 2008, and as amended. <br />NONPOINT SOURCE — Nutrient and pollution sources not discharged from a <br />single point e.g. runoff from agricultural fields, feedlots or urban landscapes. <br />NON -DEGRADATION — Section 303 (Title 33 of United States Code [U.S.C.I <br />1313) of the Clean Water Act (CWA) requires states and authorized tribes to adopt <br />water quality standards for waters of the U.S. within their applicable jurisdictions to <br />maintain their chemical physical and biological integrity. No significant increase in <br />stormwater runoff or pollutant loads from 2005/2006 numerical standards is <br />permitted. <br />NORMAL WATER LEVEL — For a reservoir with a fixed overflow, means the <br />lowest crest level of that overflow. For a reservoir whose outflow is controlled wholly <br />or partly by movable gates, siphons or other means, it is the maximum level to which <br />water may rise under normal operating conditions, exclusive of any provision for <br />flood surcharge. For a closed depression wetland, it is the maximum level to which <br />the water may rise under normal precipitation conditions exclusive of any provision <br />for flood surcharge. <br />NURP — The Nationwide Urban Runoff Program developed by the Environmental <br />Protection Agency to study stormwater runoff from urban development. <br />ORDINARY HIGH WATER LEVEL - as defined by the Minnesota Department of <br />Natural Resources means the boundary of water basins, watercourses, public waters, <br />and public waters wetlands, and: <br />1 The ordinary high water level is an elevation delineating the highest water <br />level that has been maintained for a sufficient period of time to leave evidence <br />upon the landscape commonly the point where the natural vegetation changes <br />from predominantly aquatic to predominantly terrestrial; <br />2. For watercourses, the ordinary high water level is the elevation of the top of <br />the bank of the channel; and <br />3. For reservoirs and flowages, the ordinary high water level is the operating <br />elevation of the normal summer pool. <br />PRE -DEVELOPMENT CONDITION — The land use on a site that exists <br />immediately prior to a proposed alteration All pre -development Runoff Curve <br />Numbers must reference the Minnesota Hydrology Guide. <br />PUBLIC WATERS — Any waters as defined in Minnesota Statutes, section <br />103G.005, subdivision 15. <br />
