<br /> 38. "Stormwater Pollution Prevention Program"or"SWPPP" means a comprehensive program
<br /> developed by the permittee to manage and reduce the discharge of pollutants in stormwater to and
<br /> from the small MS4.
<br /> 39. "Structural Stormwater BMP" means a stationary and permanent BMP that is designed,
<br /> constructed and operated to prevent or reduce the discharge of pollutants in stormwater.
<br /> 40. "Total Maximum Daily Load" or"TMDL" means the sum of the individual Waste Load Allocations
<br /> for point sources and load allocations for nonpoint sources and natural background, as more fully
<br /> defined in 40 CFR § 130.2, paragraph (i). A TMDL sets and allocates the maximum amount of a
<br /> pollutant that may be introduced into a water of the state and still assure attainment and
<br /> maintenance of water quality standards. (Minn.
<br /> R. 7052.0010 subp. 42)
<br /> 41. "Waste Load Allocation"or"WLA" means the portion of a receiving water's loading capacity that is
<br /> allocated to one of its existing or future point sources of pollution, as more fully defined in Code of
<br /> Federal Regulations,title 40, section 130.2, paragraph (h). In the absence of a TMDL approved by
<br /> USEPA under 40 CFR § 130.7, or an assessment and remediation plan developed and approved
<br /> according to Minn. R. subp. I.C, a WLA is the allocation for an individual point source
<br /> that ensures that the level of water quality to be achieved by the point source is derived from and
<br /> complies with all applicable water quality standards and criteria. (Minn. R. 7052.0010 subp. 45)
<br /> 42. "Water pollution" means (a)the discharge of any pollutant into any waters of the state or the
<br /> contamination of any waters of the state so as to create a nuisance or render such waters unclean,
<br /> or noxious, or impure so as to be actually or potentially harmful or detrimental or injurious to public
<br /> health, safety or welfare, to domestic, agricultural, commercial, industrial, recreational or other
<br /> legitimate uses, or to livestock, animals, birds, fish or other aquatic life; or(b)the alteration made or
<br /> induced by human activity of the chemical, physical, biological, or radiological integrity of waters of
<br /> the state. (Minn. Stat. § 115.01, subd. 13)
<br /> 43. "Water Quality Standards" means those provisions contained in Minn. R. 7050 and 7052.
<br /> 44. "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
<br /> accumulations of water, surface or underground, natural or artificial, public or private, which are
<br /> contained within, flow through, or border upon the state or any portion thereof. (Minn. Stat.
<br /> § 115.01, subd. 22.)
<br /> 45. "Wetlands"are those areas that are inundated or saturated by surface water or groundwater at a
<br /> frequency and duration sufficient to support, and that under normal circumstances do support, a
<br /> prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally
<br /> include swamps, marshes, bogs, and similar areas. Constructed wetlands designed for wastewater
<br /> treatment are not waters of the state. Wetlands must have the following attributes:
<br /> 1. A predominance of hydric soils
<br /> 2. Inundated or saturated by surface water or groundwater at a frequency and duration sufficient
<br /> to support a prevalence of hydrophytic vegetation typically adapted for life in a saturated soil
<br /> condition and
