into the ground. Common impervious surfaces include,but are not limited to,roof tops,walkways,
<br /> patios,driveways,parking lots or storage areas,concrete or asphalt paving,gravel roads,packed
<br /> earthen materials,or other surfaces which similarly impede the natural infiltration of surface and
<br /> storm water runoff.
<br /> 10.MAXIMUM EXTENT PRACTICABLE(MEP): A standard for water quality that applies to all
<br /> MS4 operators regulated under the NPDES program. Since no precise definition of MEP exists,it
<br /> allows for maximum flexibility on the part of MS4 operators as they develop and implement their
<br /> programs to reduce the discharge of pollutants to the maximum extent practicable,including
<br /> management practices,control techniques and system,design and engineering methods,and such
<br /> other provisions as the Administrator or the State determines appropriate for the control of
<br /> pollutants.
<br /> 11.MECHANICAL CLEANING TECHNIQUES: Arranging the collision between the substance being
<br /> removed and some object. Mechanical cleaning techniques include: sweeping,shoveling,or
<br /> blowing. This does NOT include using water to clean the surface.
<br /> 12.MPCA: The Minnesota Pollution Control Agency.
<br /> 13.MUNICIPAL SEPARATE STORM SEWER SYSTEM(MS4): The system of conveyances
<br /> (including sidewalks,roads with drainage systems,municipal streets,catch basins,curbs,gutters,
<br /> ditches,channels,or storm drains)owned and operated by the City and designed or used for
<br /> collecting or conveying storm water,and which is not used for collecting or conveying sewage.
<br /> 14.NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM(NPDES): The national
<br /> program for issuing,modifying,revoking,and reissuing,terminating,monitoring,and enforcing
<br /> permits,and imposing and enforcing pretreatment requirements under sections 307,318,402,and
<br /> 405 of the Clean Water Act,United States Code,title 33,sections 1317, 1328, 1342,and 1345.
<br /> 15.PERSON: Any individual,firm,corporation,partnership,franchise,association or governmental
<br /> entity.
<br /> 16.PERVIOUS SURFACE: Pervious areas permit water to enter the ground by virtue of their porous
<br /> nature or by large voids in the material. Commonly pervious areas have vegetation growing on
<br /> them.
<br /> 17.POLLUTANT: Any substance which,when discharged has potential to or does any of the
<br /> following:
<br /> a. Interferes with state designated water uses;
<br /> b. Obstructs or causes damage to waters of the state;
<br /> c. Changes water color,odor,or usability as a drinking water source through causes not attributable
<br /> to natural stream processes affecting surface water or subsurface processes affecting groundwater;
<br /> d. Adds an unnatural surface film on the water;
<br /> e. Adversely changes other chemical,biological,thermal,or physical condition,in any surface
<br /> water or stream channel;
<br /> f. Degrades the quality of groundwater;or
<br /> g. Harms human life,aquatic life,or terrestrial plant and wildlife; A Pollutant includes but is not
<br /> limited to dredged soil,solid waste,incinerator residue,garbage,wastewater sludge,chemical
<br /> waste,biological materials,radioactive materials,rock,sand,dust,industrial waste,sediment,
<br /> nutrients,toxic substance,pesticide,herbicide,trace metal,automotive fluid,petroleum-based
<br /> substance,wastewater,and oxygen-demanding material.
<br /> 18.POLLUTE: To discharge pollutants into waters of the state.
<br /> 19.POLLUTION: The direct or indirect distribution of pollutants into waters of the state.
<br /> 20.PREMISES:Any building,lot,parcel of land,or portion of land whether improved or unimproved
<br /> including adjacent sidewalks and parking strips
<br /> 21.SANITARY SEWER: a pipe,conduit,or sewer owned,operated,and maintained by the City and
<br /> which is designated by the Public Works Director as one dedicated to the exclusive purpose of
<br /> carrying sanitary wastewater to the exclusion of other matter
<br /> 22.STATE DESIGNATED WATER USES: Uses specified in state water quality standards.
