A completed application for activities regulated by this permit. <br />C. Best Management Practices (BMPs). Erosion and sediment control and water quality <br />management practices that are the most effective and practicable means of control1ing, <br />preventing, and minimizing degradation of surface water, including construction-phasing, <br />minimizing the length oftime soil areas are exposed, prohibitions, and other management <br />practices published by state or designated area wide planning agencies. <br /> <br />D. <br /> <br />Examples ofBMPs can be found in Protecting WaterOualitv in Urban Areas, Minnesota <br />Pollution Control Agency 1989, and Storm Water Manag.ement for Construction <br />Activities: Developing Pol1ution Prevention Plans and Best Management Practices, U.S. <br />Environmental Protection Agency 1992 as a reference for BMPs, and Erosion Control <br />Design Manual, Minnesota Department of Transportation, et al, 1993. <br />Development. The construction, installation or alteration of any structure; the extraction, <br />filling, clearing or other alteration of land or vegetation; the change of cross section of <br />any water body of watercourse; the subdivision of land per ordinance. <br />Discharge. The conveyance, channeling, runoff, or drainage, of storm water, including <br />snow melt, from a construction site. <br />Energy Dissipation. The methods employed at pipe outlets to prevent erosion. Examples <br />include, but are not limited to; aprons, riprap, splash pads, and gabions ~vhich are <br />designed to prevent erosion. <br />Erosion. The wearing away of soil by rainfal1, surface water runoff, wind, or ice <br />movement. <br />Erosion Control. Methods employed to prevent erosion. Examples include soil <br />stabilization practices, horizontal slope grading, temporary or permanent cover, and <br />construction phasing. <br />Exposed Soil Areas. All areas of the construction site where the perennial vegetation <br />(including trees, shrubs, and brush) has been removed. This includes topsoil stockpile <br />areas, borrow areas and disposal areas within the construction site. <br />Final Stabilization. All soil disturbing activities at the site have been completed, and that <br />a uniform perennial vegetative cover with a density of 70 percent (70%) ofthe cover for <br />unpaved areas and areas not covered by permanent structures has been established or <br />equivalent permanent stabilization measures have been employed. Examples of <br />vegetative cover practices can be found in Supplemental Specifications to the 1988 <br />Standard Specifications for Construction (Minnesota Department of Transportation, <br />1991). <br />Impervious Surface. A constructed hard surface the either prevents or retards the entry of <br />water into the soil and causes water to run off the surface in greater quantities and at an <br />increased rate of flow than prior to development. Examples include rooftops, sidewalks, <br />patios, driveways, parking lots, storage areas, and concrete, asphalt, or gravel roads. <br />Q'\TIer. The person or part possessing the title of the land on which the construction <br />activities wil1 occur; or if the construction activity is for a lease holder, the party or <br />individual identified as the lease holder; or the contracting government agency <br />responsible for the construction activity. <br />Paved Surface. A constructed hard"~1l~f3:c;(:1l1ad(:.~Lasphitl~,c()l1.c.r~~eorn()tJ:l~~.paY~1l1~.nt <br />material. Examples include, but are not limited to, roads, sidewalks, driveways and <br />parking lots. <br /> <br />E. <br /> <br />Page 4 of9 <br /> <br />..-.-f Deleted: smooth <br />
