• • RULE D EROSION AND SEDIMENT CONTROL PLANS 1. POLICY. It is the policy of the Board of Managers to prevent erosion of soil into surface water systems by requiring preparation and implementation of erosion and sediment control plans for land- disturbing activities. 2. REGULATION. An erosion and sediment control plan must be submitted, and a permit received from the District, for (a) the grading, excavation, filling or stockpiling of more than fifty (50) cubic yards of earth or other erodible material; or (b) surface soil disturbance or removal of vegetative cover on five thousand (5,000) square feet or more of land. This requirement does not apply to plowing as part of an ongoing farming operation. 3. DESIGN CRITERIA FOR EROSION CONTROL PLANS. Erosion and Sediment Control Plans must comply with the following criteria: (a) Natural site topography and soil conditions must be specifically addressed to reduce erosion and sedimentation during construction and after project completion. (b) Site erosion and sediment control practices must be consistent with the Minnesota Pollution Control Agency document "Protecting Water Quality in Urban Areas" (1994), as amended, and District- specific written design guidance and be sufficient to retain sediment on -site. (c) The project must be phased as best possible to minimize disturbed areas and removal of existing vegetation until necessary for project progress. (d) The District may require additional erosion and sediment control measures on areas with a continuous slope leading to a sensitive, impaired or special water body, stream, ditch or wetland to assure retention of sediment on site. (e) The plan must include conditions adequate to protect facilities to be used for post - construction stormwater infiltration. 4. REQUIRED EXHIBITS. The following exhibits must accompany the permit application. One set, full size (22 inches by 34 inches); two sets, reduced to maximum size of 11 inches by 17 inches. (a) An existing and proposed topographic map which clearly indicates all hydrologic features and areas where grading will expose soils to erosive conditions. The Plan must also indicate the direction of all site runoff. (b) Tabulation of the construction implementation schedule. (c) Name, address and phone number of party responsible for maintenance of all erosion and sediment control measures. (d) Clear identification of all temporary erosion and sediment control measures which will remain in place until permanent vegetation is established. Examples of temporary measures include, but are not limited to: seeding with perennial vegetation, mulching, sodding, silt fence, erosion control blanketing, and stormwater inlet protection devices.
