<br /> Chapter 30- LAND DEVELOPMENT REGULATIONS
<br /> ARTICLE VII. STORMWATER MANAGEMENT
<br /> The term "ordinary high water mark" is further defined in Minnesota Rule 6120.2500, subpart 11. The
<br /> Minnesota Department of Natural Resources' area hydrologist determines ordinary high water marks.
<br /> Paved surface means a constructed hard, smooth surface made of asphalt, concrete or other
<br /> pavement material. Examples include, but are not limited to, roads, sidewalks, driveways and parking
<br /> lots.
<br /> Permanent cover means "final stabilization." Examples include grass, gravel, asphalt, and concrete.
<br /> See also the definition of"final stabilization."
<br /> Receiving waters means the water where the discharge goes.
<br /> Sanitary waste facility means all property, real or personal, including negative and positive
<br /> easements and water and air rights, which is or may be needed or useful for the processing or disposal of
<br /> waste, except property for the collection of the waste and property used primarily for the manufacture of
<br /> scrap metal or paper. Waste facility includes but is not limited to transfer stations, processing facilities,
<br /> and disposal sites and facilities.
<br /> Sediment means the product of an erosion process; solid material both mineral and organic, that is in
<br /> suspension, is being transported, or has been moved by water, wind, or ice, and has come to rest on the
<br /> earth's surface either above or below water level.
<br /> Sedimentation means the process or action of depositing sediment.
<br /> Sediment control means the methods employed to prevent sediment from leaving the development
<br /> site. Sediment control practices include silt fences, sediment traps, earth dikes, drainage swales, check
<br /> dams, subsurface drains, pipe slope drains, storm drain inlet protection, and temporary or permanent
<br /> sedimentation basins.
<br /> Soil means the unconsolidated mineral and organic material on the immediate surface of the earth.
<br /> For the purposes of this document stockpile of gravel, aggregate, concrete or bituminous materials are
<br /> not considered "soil" stockpiles.
<br /> Stabilized 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 under Minnesota Rule 7077.0105, subpart 41 b storm water, "means precipitation runoff,
<br /> storm water runoff, snow melt runoff, and any other surface runoff and drainage." (According to the
<br /> Federal Code of Regulations under 40 CFR 122.26 [b][13], "Storm water means storm water runoff, snow
<br /> melt runoff and surface and drainage."). Stormwater does not include construction site dewatering.
<br /> Stormwater pollution control plan means a joint storm water and erosion and sediment control plan
<br /> that is a document containing the requirements of Section 4 of the NPDES permit, that when
<br /> implemented will decrease soil erosion on a parcel of land and off-site nonpoint pollution. It involves both
<br /> temporary and permanent controls.
<br /> Structure 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 /> storage areas.
<br /> Subdivision 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 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 swales means a vegetated earthen channel that conveys stormwater, while
<br /> treating the stormwater by biofiltration. Such swales remove pollutants by both filtration and infiltration.
