17. Documentation that the project applicant has applied for the NPDES Permit from the Minnesota Pollution Control Agency (MPGA), 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. (fl The plan must include conditions adequate to protect facilities to be used for post -construction stormwater infiltration. (g) The plan must include conditions to minimize off-site sediment transport on trucks and equipment. (h) The plan must minimize work in and adjacent to water bodies and wetlands. (i) Stable slopes shall be maintained throughout the construction process. (j) Steep slopes and the need for high cuts and fills shall be avoided (no slopes greater than 3(h):1(v), except as approved by the City engineer).
