Applicant also Ineansappl es to that person's agents, employees, and others acting under this person's direction. Best management practices (BMP's) tll re 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 of BMP'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. ") Buffer means 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 ateshall be designated with permanent markers. Construction a6a U or mwfing agt means a disturbance to the land that results in a chap a in the topography, existing soil cover (both vegetative and non- vegetative),,r the existing soil topography that may result in accelerated stormwater runoff and/or. additional runoff volume leading to soil erosion and movement of sediment into surface waters or draina e systems. Examples of construction activi may include clearing, adin filli.n and excavating. Construction activi T includes the disturbance of land area that is a part of a larger common 121an of development or sale if the lar er common 121an will ultimately disturb 5 000 square feet or more of land areas. Developer means a person, firm, corporation, sole proprietorship, partnership, state agency, or political subdivision thereof engaged in a land disturbance activity. 2
