<br />B. Application. 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 controlling,
<br />preventing, and minimizing degradation of surface water, including construction-phasing,
<br />minimizing the length of time 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 ofHMPs can be found in Protecting Water Quality in Urban Areas, Minnesota
<br />Pollution Control Agency 1989, and Storm Water Management for Construction
<br />Activities: Developing Pollution 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 aI, 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 ofland 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 which are
<br />designed to prevent erosion.
<br />Erosion. The wearing away of soil by rainfall, 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. 1ms 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%) of the cover for
<br />llllpaved 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 a,T}d 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 />Owner. The person or part possessing the title of the land on which the construction
<br />activities will 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,. Sllfface I11lld~oK llsp'hlllt, c:oI1cret~ ~r otl1~IJ)a\Tell1~Ilt __
<br />material. Examples include, but are not limited to, roads, sidewalks, driveways and
<br />parking lots.
