<br />center of a stormwater feature. [Minn. R. 7090]
<br />27.15
<br />"High Flow Bypass" means a function of an inlet device that allows a certain flow of water through, but diverts any higher
<br />flows away. High flow bypasses are generally used for BMPs that can only treat a designed amount of flow and that would
<br />be negatively affected by higher flows. [Minn. R. 7090]
<br />27.16
<br />"Illicit Discharge" means any discharge to a municipal separate storm sewer that is not composed entirely of stormwater
<br />except discharges pursuant to a NPDES permit (other than the NPDES permit for discharges from the municipal separate
<br />storm sewer) and discharges resulting from firefighting activities. [40 CFR 122.26(b)(2)]
<br />27.17
<br />"Impaired Water" means waters identified as impaired by the Agency, and approved by the USEPA, pursuant to
<br />section 303(d) of the Clean Water Act (33 U.S.C. 303(d)). [Minn. R. 7090]
<br />27.18
<br />"Linear project" means construction of new or fully reconstructed roads, trails, sidewalks, or rail lines that are not part
<br />of a common plan of development or sale. For example, roads being constructed concurrently with a new residential
<br />development are not considered linear projects because they are part of a common plan of development or sale.
<br />[Minn. R. 7090]
<br />27.19
<br />"Maximum Extent Practicable" or "MEP" means the statutory standard (33 U.S.C. 1342(p)(3)(13)(iii)) that establishes the
<br />level of pollutant reductions that an owner or operator of regulated MS4s must achieve. The USEPA has intentionally not
<br />provided a precise definition of MEP to allow maximum flexibility in MS4 permitting. The pollutant reductions that
<br />represent MEP may be different for each small MS4, given the unique local hydrologic and geologic concerns that may exist
<br />and the differing possible pollutant control strategies. Therefore, each permittee will determine appropriate BMPs to
<br />satisfy each of the six Minimum Control Measures (MCMs) through an evaluative process. The USEPA envisions application
<br />of the MEP standard as an iterative process. [Minn. R. 7090]
<br />27.20
<br />"Municipal separate storm sewer system" or "MS4" means a conveyance or system of conveyances including roads with
<br />drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains:
<br />a. owned or operated by a state, city, town, county, district, association, or other public body, created by or pursuant to
<br />state law, having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special
<br />districts under state law such as a sewer district, flood control district, or drainage district or similar entity, or an Ind Ian
<br />tribe or an authorized Indian tribe organization, or a designated and approved management Agency under section 208 of
<br />the federal Clean Water Act, United States Code, title 33, section 1288, that discharges into waters of the state;
<br />b. designed or used for collecting or conveying stormwater;
<br />c. that is not a combined sewer; and
<br />d. that is not part of a publicly owned treatment works as defined in 40 CFR 122.2.
<br />Municipal separate storm sewer systems do not include separate storm sewers in very discrete areas, such as individual
<br />buildings. [Minn. R.7090.0080, subp.8]
<br />27.21
<br />"New Permittee" means an owner/operator of a small MS4 that has not been authorized to discharge stormwater under a
<br />previously issued General Stormwater Permit for small MS4s in the state of Minnesota and that applies for, and obtains
<br />coverage under the General Permit. [Minn. R. 7090]
<br />27.22
<br />"Non-Stormwater Discharge" means any discharge not composed entirely of stormwater. [Minn. R. 7090]
<br />27.23
<br />"Operator" means the person with primary operational control and legal responsibility for the MS4. [Minn. R. 7090.0080,
<br />subp. 10]
<br />27.24
<br />"Outfall" means the point source where a MS4 discharges to a receiving water, or the stormwater discharge permanently
<br />leaves the permittee's MS4. It does not include diffuse runoff or conveyances that connect segments of the same stream
<br />or water systems (e.g., when a conveyance temporarily leaves an MS4 at a road crossing). [Minn. R. 7090]
<br />27.25
<br />"Owner" means the person that owns the MS4. [Minn. R. 7090.0080, subp. 11]
<br />27.26
<br />"Permittee" means a person or persons, that signs the permit application submitted to the Agency and is responsible for
<br />compliance with the terms and conditions of the General Permit. [Minn. R. 7090]
<br />27.27
<br />"Person" means the state or any Agency or institution thereof, any municipality, governmental subdivision, public or private
<br />corporation, individual, partnership, or other entity, including, but not limited to, association, commission or any interstate
<br />body, and includes any officer or governing or managing body of any municipality, governmental subdivision, or public or
<br />private corporation, or other entity. [Minn. Stat. 115.01, subd. 10]
