The applicant shall submit a Storm Water Pollution Prevention Plan (SWP3) consistent with the requirements set forth in the most recent Ohio EPA NPDES General Construction Permit. For specific requirements of a SWP3 the designer shall refer to SWP3 Check List. The SWP3 must address erosion and sediment control during construction as well as post construction practices. Post construction practices must meet the requirements of the most recent Ohio EPA General Construction Stormwater Permit. The SWP3 shall incorporate measures as recommended by the most current edition of Rainwater and Land Development Manual as published by the Ohio Department of Natural Resources .
(a) Non-structural Post Construction Water Quality Practices. Non-structural post construction best management practices include preservation, planning or procedures that direct development away from water resources or limit creation of impervious surfaces. Practices such as conservation easements, riparian and wetland setbacks, and conservation subdivision design are all non-structural controls.
(1) All non-structural water quality practices must be protected from disturbance through the construction phase of the project.
(2) All non-structural water quality practices must be protected in perpetuity through the use of appropriate legal tools. All easement or conservation areas must appear on the final plat and be disclosed to potential buyers.
(b) Structural Water Quality Practices. Structural post construction best management practices are permanent features constructed to provide treatment of storm water runoff either through storage, filtration or infiltration.
(1) All structural water quality practices must be established prior to the completion of the project. Structural water quality practices should be made functional once the disturbed areas on site are stabilized. If detention/retention facilities were used for sediment control during development sediments must be removed prior to the basin being used for post construction storm water quality.
(2) Maintenance. The post construction water quality practice must be maintained in perpetuity by those parties identified in the SWP3 or the Storm Water Management Maintenance Agreement.
