• • DRAFT 01 -19 -2011 removal, grading, excavation, fill, and other disturbance; areas of soil or earth material storage; quantities of soil or earth material to be removed, placed, stored, or otherwise moved on site, and delineated limits of disturbance. 15. Location and type of all temporary and permanent erosion prevention, sediment control, stormwater runoff, and soil stabilization BMPs, along with procedures to be used to establish additional temporary BMPs as necessary for the site conditions during construction. Standard plates and/or specifications for the BMP's used on the project must be included in the final plans and specifications for the project. Location and design of temporary sediment basins where 10 acres or more (5 acres or more for special or impaired waters) are disturbed and drained to a single point. When site restrictions do not allow for a temporary sediment basin or less than the required acreage is being developed, temporary sediment basins where appropriate are encouraged, but not required in areas with steep slopes or highly erodible soils or to take equivalent measures such as smaller basins, check dams, and vegetated buffer strips. 16. Methods to be used for final stabilization of all exposed soil areas. 17. Documentation that the project applicant has applied for the NPDES Permit from the Minnesota Pollution Control Agency (MPCA), when applicable. 18. A Stormwater Pollution Prevention Plan for projects that require an NPDES Permit. (3) Grading, Erosion and Sediment Control Plan Design Standards Grading, Erosion and Sediment Control Plans must comply with the following criteria: (a) All plans shall be consistent with National Pollutant Discharge Elimination Permit (NPDES) requirements, the Lino Lakes Engineering Design Standards, the Lino Lakes Stormwater Design Standards, and the filing or approval requirements of Rice Creek Watershed District, Vadnais Lakes Watershed Management Organization, Anoka County, Minnesota Department of Natural Resources, Minnesota Department of Transportation, U.S. Army Corps of Engineers, State of Minnesota Stormwater Manual or other regulatory agencies. (b) Natural site topography and soil conditions must be specifically addressed to reduce erosion and sedimentation during construction and after project completion. (c) 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 City - specific written design guidance and be sufficient to retain sediment on -site. (d) The project must be phased as best possible to minimize disturbed areas and removal of existing vegetation until necessary for project progress. (e) The City 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.
