A report detailing the proposed conveyance, storage, distribution, generation, use, treatment, and/or disposal of any stormwater runoff or sewage. If applicable, a stormwater pollution prevention plan (SWPPP) shall be submitted. The SWPPP shall document the methods for the removal of oil, gasoline, and other contaminants from runoff by the use of treatment swales, sediment traps, oil/gas separator, and/or other devices. To the maximum extent, all runoff from impervious surfaces shall be recharged to groundwater in a method to be approved by the Planning Board. Recharge may be achieved through site design that incorporates natural drainage patterns and vegetation, and through use of stormwater infiltration basins and trenches, porous pavement or similar systems. Long-term maintenance measures shall be described in the management plan.
