. . . and words in the singular number include the plural number. The words "shall" and "must" are always mandatory and not merely directive. Applicant means any person or entity that applies for a building permit, subdivision approval, or a permit to allow land-disturbing activities. Applicant also means that person's agents, employees, and others acting under this person's direction. Best Management Practices (BMP's) means erosion and sediment control and water quality management practices that are the most effective and practicable means of controlling, preventing, and minimizing the degradation of surface water, including construction-phasing, minimizing the length of time soil areas are exposed, prohibitions, and other management practices published by state or designated area-wide planning agencies. (Examples ofBMP's can be found in the current versions of the Minnesota Pollution Control Agency's publications, "Protecting Water Quality in Urban Areas," and, "Storm-Water and Wetlands: Planning and Evaluation Guidelines for Addressing Potential Impacts of Urban Storm-Water and Snow-Melt Runoff on Wetlands," the United States Environmental Protection Agency's, "Storm Water Management for Construction Activities: Developing Pollution Prevention Plans and Best Management Practices," (as a reference for BMP's) and the Minnesota Department of Transportation's, "Erosion Control Design Manual.") BujJermeans a protective vegetated zone located adjacent to a natural resource, such as a water of the state, that is subject to direct or indirect human alteration. Such a buffer strip is an integral part of protecting an aquatic ecosystem through filtering, pollutants and providing adjacent habitat. The width of a buffer strip is the width along each bank of a stream. Therefore, a 30-foot wide stream with 100 foot buffer strips has a total width of 230 feet. Acceptable buffer vegetation includes preserving existing predevelopment vegetation and/or planting locally distributed native Minnesota trees, shrubs and grassy vegetation. Alteration of buffers is strictly limited. Buffer areas are designated with permanent markers. Devefopermeans a person, firm, corporation, sole proprietorship, partnership, state agency, or political subdivision thereof engaged in a land disturbance activity. Discharge means the release, conveyance, channeling, runoff, or drainage, of storm water, including snowmelt, from a construction site. Energy Dissipation means the methods employed at pipe outlets to prevent erosion. Examples include, but are not limited to; aprons, riprap, splash pads, and gabions that are designed to prevent erosion. Erosion means any process that wears away the surface of the land by the action of water, wind, ice, or gravity. Erosion can be accelerated by the activities of people and nature. Erosion Control Refers to methods employed to prevent erosion. Examples include soil stabilization practices, horizontal slope grading, temporary or permanent cover, and construction phasing. 2
