8 <br /> NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) <br />STORMWATER DISCHARGE PERMIT. A permit issued by the Minnesota Pollution <br />Control Agency that authorizes the discharge of pollutants to the waters of the state. <br /> NATIONWIDE URBAN RUNOFF PROGRAM (NURP). Urban Runoff Program <br />developed by the Environmental Protection Agency to study stormwater runoff from <br />urban development. <br /> ORDINARY HIGH WATER LEVEL (OHWL). The highest water level elevation that <br />has been maintained for a sufficiently long period of time to leave evidence upon the <br />landscape. The OHWL is commonly that point where the natural vegetation changes <br />from predominantly aquatic to predominantly terrestrial. If an OHWL has been <br />established for a waterbody by the Minnesota Department of Natural Resources, it will <br />constitute the OHWL under this definition. <br /> OWNER. The person or party possessing the title of the land on which the <br />construction activities will occur; or if the construction activity is for a lease, easement, <br />or mineral rights license holder, the party or individual identified as the lease, easement, <br />or mineral rights license holder; or the contracting government agency responsible for <br />the construction activity. <br /> POLLUTANT. A substance that pollutes something, especially water or the <br />atmosphere. <br /> <br /> PUBLIC LINEAR PROJECT. A project involving a roadway, sidewalk, trail or utility <br />not part of an industrial, commercial, institutional or residential development. <br /> RECONSTRUCTION. Removal of an impervious surface such that the underlying <br />structural aggregate base is effectively removed and the underlying native soil exposed. <br /> REGIONAL FLOOD. A flood which is representative of large floods known to have <br />occurred generally in Minnesota and reasonably characteristic of what can be expected <br />to occur on an average frequency in the magnitude of the 1% chance or 100-year <br />recurrence interval. REGIONAL FLOOD is synonymous with the term BASE <br />FLOOD used in the Flood Insurance Study. <br /> SEASONAL HIGH WATER TABLE. The highest known seasonal elevation of <br />groundwater as indicated by redoximorphic features such as mottling within the soil. <br /> SATURATED SOIL. The highest seasonal elevation in the soil that is in a reduced <br />chemical state because of soil voids being filled with water. Saturated soil is evidenced <br />by the presence of mottled features or other information. <br /> SEDIMENT CONTROL. Methods employed to prevent sediment from leaving the <br />site. SEDIMENT CONTROL practices include silt fences, sediment traps, earth dikes, <br />drainage swales, check dams, subsurface drains, pipe slope drains, storm drain inlet <br />protection, and temporary or permanent sedimentation basins. <br /> SHORELAND. Land located within the following distances from the ordinary high <br />water elevation of public waters:
