Page 7 of 7 shall be provided to prevent vandalism. Storage and disposal of hazardous waste shall be in compliance with MPCA regulations. c. External washing of trucks and other construction vehicles must be limited to a defined area of the site. Runoff shall be contained and waste properly disposed of. No engine degreasing is allowed on site. d. The City of Mounds View prohibits discharges of any material other than storm water, and discharges from dewatering or basin draining activities. Prohibited discharges include but are not limited to vehicle and equipment washing, maintenance spills, wash water, and discharges of oil and other hazardous substances. 7. Final Stabilization A. The Permittee must ensure final stabilization of the project. The Permittee shall submit a NOT within 30 days after final stabilization has been achieved, or another Permittee has assumed control on all areas of the project that have not achieved final stabilization. Final stabilization can be achieved in one of the following ways. a. All soil disturbing activities at the site have been completed and all soils will be stabilized by a uniform perennial vegetative cover with a density of at least 70 percent over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions and; i. All drainage ditches, constructed to drain water from the site after construction is complete, must be stabilized to preclude erosion; and ii. All temporary synthetic, and structural erosion prevention and sediment control BMPs (such as silt fence) must be removed as part of the site final stabilization; and iii. The Permittee must clean out all sediment from conveyances and from temporary sedimentation basins that are to be used as permanent water quality management basins. Sediment must be stabilized to prevent it from washing back into the basin, conveyances or drainage ways discharging off-site or to surface waters. The cleanout of permanent basins must be sufficient to return the basin to design capacity. b. For residential construction only, final stabilization has been achieved when: i. Temporary erosion protection and down gradient perimeter control for individual lots has been completed and the residence has been transferred to the homeowner. ii. The Permittee must distribute the MPCA “homeowner factsheet” to the homeowner so the homeowner is informed for the need, and benefits, of final stabilization.
