. . . Erosion and Sediment Practice Specifications or Practice means the management procedures, techniques, and methods to control soil erosion and sedimentation as officially adopted by either the state, county, city or local watershed group, whichever is more stringent. Exposed Soil Areas means all areas of the construction site where the vegetation (trees, shrubs, brush, grasses, etc.) or impervious surface has been removed, thus rendering the soil more prone to erosion. This includes topsoil stockpile areas; borrow areas and disposal areas within the construction site. It does not include stockpiles or surcharge areas of gravel, concrete or bituminous. Once soil is exposed it is considered "exposed soil," until it meets the definition of "final stabilization." Filter Strips means a vegetated section of land designed to treat runoff as overland sheet flow. They may be designed in any natural vegetated form from a grassy meadow to a small forest. Their dense vegetated cover facilitates pollutant removal and infiltration. Final Stabilization means that all soil disturbing activities at the site have been completed, and that a uniform perennial vegetative cover with a density of seventy-five (75) percent of the cover for unpaved areas and areas not covered by permanent structures has been established, or equivalent permanent stabilization measures have been employed. Simply sowing grass seed is not considered final stabilization. (Examples of vegetative cover practices can be found in the current version of the Minnesota Department of Transportation's publication, "Supplemental Specifications to the (year if the latest update) Standard Specifications for Construction.") Hydric Soils means soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part. Hydrophytic Vegetation means Macrophytic (large enough to be observed by the naked eyetplant life growing in water, soil or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content. Imperoious Surface means a constructed hard surface that either prevents or retards the entry of water into the soil, and causes water to run off the surface in greater quantities and at an increased rate of flow than existed prior to development. Examples include rooftops, sidewalks, patios, driveways, parking lots, storage areas, and concrete, asphalt, or gravel roads. Land Disturbance Activity means any land change that may result in soil erosion from water or wind and the movement of sediments into or upon waters or lands within this government's jurisdiction, including clearing & grubbing, grading, excavating, transporting and fllling of land. Within the context of this rule, land disturbance activity does not mean: A. Individual home gardens, minor landscaping, repairs, and maintenance work. B. Construction, installation, and maintenance of fences, signs, posts, poles, and electric, telephone, cable television, utility lines or individual service connections to these utilities, which result in creating under five thousand (5,000) square feet of exposed soil. 3
