<br /> Slope is the incline of a ground surface expressed as a ratio of horizontal distance to vertical
<br /> distance.
<br /> Special Water means a surface water or receiving water that is of a high quality or is deemed
<br /> worthy to receive extra protection.
<br /> Stormwater. Under Minnesota Rule 7077.0105, Subpart 41b), storm water, "means precipitation
<br /> runoff, stormwater runoff, snow melt runoff and any other surface runoff and drainage".
<br /> According to the Code of Federal Regulations (CFR), under 40 CFR 122.26 [b][13],
<br /> "Stormwater means storm water runoff, snow melt runoff and surface and drainage". Stormwater
<br /> does not include construction site dewatering.
<br /> Storm sewer system, includes but is not limited to, the combination of roadway gutters, roadway
<br /> section ditches, culverts, storm sewer piping, overflow channels, infiltration trenches, detention
<br /> and retention water quality treatment basins and other methods or devices used for capturing,
<br /> conveying, controlling and treating stormwater and snow melt runoff.
<br /> Stormwater Pollution Prevention Plan is joint stormwater, erosion prevention and sediment
<br /> control plan that is a document containing the requirements of Section I. When implemented,the
<br /> plan will define the methods to be used to reduce soil erosion on a parcel of land and off-site
<br /> non-point pollution. The plan involves both temporary and permanent controls.
<br /> Stormwater pond(also referred to as wet sedimentation basin, wet retention basin, or simply wet
<br /> pond) is a man-made or modified natural basin constructed to capture and retain stormwater
<br /> runoff for the purpose of removing pollutants and mitigating downstream water quantity impacts.
<br /> Surface Waters means all streams, ponds, lakes, marshes, wetlands, reservoirs, springs, rivers,
<br /> drainage systems, waterways, watercourses, and irrigation systems, whether natural or artificial,
<br /> public or private.
<br /> Vegetated (Grassy) swale is a vegetated earthen channel that conveys storm water while treating
<br /> the stormwater by biofiltration. Such swales aid in the removal of pollutants by both filtration
<br /> and infiltration.
<br /> Waters of the State as defined in Minnesota Statutes Section 115.01, Subdivision
<br /> 22, the term, " . . . waters of the state means all streams, lakes, ponds, marshes, watercourses,
<br /> waterways, wells, springs, reservoirs, aquifers, irrigation systems, drainage systems and all other
<br /> bodies or accumulations of water, surface or underground, natural or artificial, public or private,
<br /> which are contained within, flow through, or border upon the state or any portion thereof'.
<br /> Commentary: According to Minnesota Rules 7050.0130, Subpart A, disposal systems or
<br /> treatment works operated under either a Minnesota Pollution Control Agency(MPGA)permit or
<br /> an agency certificate of compliance are not considered "waters of the state. " Under Minnesota
<br /> Rules 7050.0130, Subpart F, constructed wetlands designed for wastewater treatment are not
<br /> "waters of the state."Also see the definition of"Wetlands".
<br /> Watercourse is a ditch, stream, creek, or other defined channel intended for the conveyance of
<br /> water, runoff, groundwater discharge or similar hydraulic or hydrologic purpose.
<br /> Wetlands. "Wetlands" means lands transitional between terrestrial and aquatic systems where the
<br /> water table is usually at or near the surface or the land is covered by shallow water. For purposes
<br /> of this definition,wetlands must have the following three attributes:
<br /> (A) have a predominance of hydric soils;
<br /> (B) are inundated or saturated by surface or ground water at a frequency and duration
<br /> sufficient to support a prevalence of hydrophytic vegetation typically adapted for
<br /> life in saturated soil conditions; and
