<br />Permanent cover means Ðfinal stabilizationÑ. Examples include grass, gravel, asphalt and concrete. See also the
<br />definition of Ðfinal stabilizationÑ.
<br />Pretreatment means directing stormwater runoff through a BMP or series of BMPs for the purpose of removing
<br />sediment and/or other pollutants prior to discharge into a receiving basin.
<br />Project is a planned undertaking resulting in changes to the condition of a property.
<br />Public Waters are waters of the state as defined in Minnesota Statutes, Section 103G.005, Subdivision 15.
<br />Retention facility is a temporary or permanent natural or manmade structure that provides for the storage of
<br />storm water runoff by means of a permanent pool of water.
<br />Runoff is rainfall, snowmelt, dewatering discharge, irrigation or any man-made sources of water flowing over
<br />the ground surface.
<br />Sediment is the product of an erosion process; solid material both mineral and organic, which is in suspension,
<br />is being transported, or has been moved by water, wind, or ice and has come to rest on the earth's surface either
<br />above or below water level.
<br />Slope is the incline of a ground surface expressed as a ratio of horizontal distance to vertical distance.
<br />Special Water means a s urface water or receiving water that is of a high quality or is deemed worthy to receive
<br />extra protection.
<br />Stormwater. Under Minnesota Rule 7077.0105, Subpart 41b), storm water, Ðmeans precipitation runoff,
<br />stormwater runoff, snow melt runoff and any other surface runoff and drainageÑ. According to the Code of
<br />Federal Regulations (CFR), under 40 CFR 122.26 \[b\]\[13\], ÐStormwater means storm water runoff, snow melt
<br />runoff and surface and drainageÑ. Stormwater does not include construction site dewatering.
<br />Storm sewer system, includes but is not limited to, the combination of roadway gutters, roadway section
<br />ditches, culverts, storm sewer piping, overflow channels, infiltration trenches, detention and retention water
<br />quality treatment basins and other methods or devices used for capturing, conveying, controlling and treating
<br />stormwater and snow melt runoff.
<br />Stormwater Pollution Prevention Plan is joint stormwater, erosion prevention and sediment control plan that is
<br />a document containing the requirements of Section I. When implemented, the plan will define the methods to be
<br />used to reduce soil erosion on a parcel of land and off-site non-point pollution. The plan involves both
<br />temporary and permanent controls.
<br />Stormwater pond (also referred to as wet sedimentation basin, wet retention basin, or simply wet pond) is a
<br />man-made or modified natural basin constructed to capture and retain stormwater runoff for the purpose of
<br />removing pollutants and mitigating downstream water quantity impacts.
<br />Surface Waters means all streams, ponds, lakes, marshes, wetlands, reservoirs, springs, rivers, drainage
<br />systems, waterways, watercourses, and irrigation systems, whether natural or artificial, public or private.
<br />Vegetated (Grassy) swale is a vegetated earthen channel that conveys storm water while treating the stormwater
<br />by biofiltration. Such swales aid in the removal of pollutants by both filtration and infiltration.
<br />Waters of the State as defined in Minnesota Statutes Section 115.01, Subdivision
<br />22, the term, Ð . . . waters of the state means all streams, lakes, ponds, marshes, watercourses, waterways, wells,
<br />springs, reservoirs, aquifers, irrigation systems, drainage systems and all other bodies or accumulations of
<br />water, surface or underground, natural or artificial, public or private, which are contained within, flow through,
<br />or border upon the state or any portion thereofÑ. Commentary: According to Minnesota Rules 7050.0130,
<br />Subpart A, disposal systems or treatment works operated under either a Minnesota Pollution Control Agency
<br />(MPCA) permit or an agency certificate of compliance are not considered Ðwaters of the state.Ñ Under
<br />Minnesota Rules 7050.0130, Subpart F, constructed wetlands designed for wastewater treatment are not
<br />Ðwaters of the state.Ñ Also see the definition of ÐWetlandsÑ.
<br />Watercourse is a ditch, stream, creek, or other defined channel intended for the conveyance of water, runoff,
<br />groundwater discharge or similar hydraulic or hydrologic purpose.
