<br /> <br />dams, subsurface drains, pipe slope drains, storm drain inlet protection, and temporary or permanent <br />sedimentation basins. <br />Soil <br />means the unconsolidated mineral and organic material on the immediate surface of the earth. For <br />the purposes of this document stockpile of gravel, aggregate, concrete or bituminous materials are not <br />considered "soil" stockpiles. <br />Stabilized <br />means the exposed ground surface after sod, erosion control blanket, riprap, or other <br />material that prevents erosion has covered it. Simply sowing grass seed is not considered stabilization. <br />Stormwater <br />" <br />under Minnesota Rule 7077.0105, subpart 41b storm water, means, “precipitation <br />runoff, storm water runoff, snow melt runoff, and any other surface runoff and drainage." (According to <br />the Federal Code of Regulations under 40 CFR 122.26 [b][13], "Storm water means storm water runoff, <br />snow melt runoff and surface and drainage."). Stormwater does not include construction site dewatering. <br />Stormwater pollution plan <br />control <br />prevention or SWPPP means a joint storm water and erosion and <br />4 <br />sediment control plan that is a document containing the requirements of Section IV of the NPDES <br />permit, that when implemented will decrease soil erosion on a parcel of land and off-site nonpoint <br />pollution. It involves both temporary and permanent controls erosion prevention, sediment control, and <br />pollution prevention practices. <br />Structure <br /> means anything manufactured, constructed, or erected, which is normally attached to or <br />positioned on land, including portable structures, earthen structures, roads, parking lots, and paved <br /> <br />storage areas. <br />Subdivision <br />means any tract of land divided into building lots for private, public, commercial, <br />industrial, etc. development. Minnesota Rule 6120.2500, subpart 17 defines subdivision as, " . . . land that <br />is divided for the purpose of sale, rent, or lease, including planned unit development." <br />Temporary protection <br />means short-term methods employed to prevent erosion. Examples of such <br />protection include: straw, mulch, erosion control blankets, wood chips, and erosion netting. <br />Vegetated or grassy <br />swales <br />swale means a vegetated earthen channel that conveys stormwater, while <br />treating the stormwater by biofiltration. Such swales remove pollutants by both filtration and infiltration. <br />Waters of the <br />state As <br />State as defined in Minnesota Statutes § 115.01, subdivision 22 the term ". . . <br />"waters of the state" means all streams, lakes, ponds, marshes, watercourses, waterways, wells, springs, <br />reservoirs, aquifers, irrigation systems, drainage systems and all other bodies or accumulations of water, <br />surface or underground, natural or artificial, public or private, which are contained within, flow through, <br />or border upon the state or any portion thereof." <br />Wet detention facility <br /> permanent <br />means a manmade structure, containing a permanent pool of <br />water, used for the temporary storage of runoff. <br />Wet retention facility The same as a wet detention facility. <br />Wetlands <br />As" . <br /> as defined in Minnesota Rules 7050.0130, subpart F, “. . . "wetlands" are those areas <br />that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to <br />support, and that under normal circumstances do support, a prevalence of vegetation typically adapted <br />for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. <br />Constructed wetlands designed for wastewater treatment are not waters of the state. Wetlands must have <br />the following attributes: <br />(1) <br /> <br />1.A predominance of hydric soils; <br /> Page <br />6 <br />
