(a) The applicant shall submit a Storm Water Pollution Prevention Plan (SWP3) consistent with the requirements set forth in the current Ohio EPA NPDES General Construction Permit. For specific requirements of a SWP3 the designer shall refer to the NPDES Ohio general construction permit and the Summit SWCD SWP3 Check List. The SWP3 must address erosion and sediment control during construction as well as post construction water quality practices. Post construction practices must meet the requirements of the NPDES Ohio general construction permit and the City of Stow.
(b) The SWP3 shall be certified by a Qualified Individual.
(c) 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 or other technical manuals approved by the Summit SWCD.
(d) Trapping Efficiency: All sediment basins and traps must maintain a minimum of 75% trapping efficiency throughout the construction period as determined by engineering calculations contained within the Summit County Water Quality and Trapping Efficiency Program. The approved program to determine trapping efficiency is available through the Summit SWCD.
(e) Soils Erodibility Reports: The Summit SWCD may require the SWP3 to include a Soils Engineering Report based upon his/her determination that the conditions of the soils are unknown or unclear to the extent that additional information is required to protect against erosion. This report shall contain all the information listed below.
(1) Data regarding the nature and erodibility of existing soils.
(2) If applicable, data regarding the nature and erodibility of the soil to be placed on the site.
(3) Conclusions and recommendations for grading purposes.
(4) Conclusions and recommended designs for interim soil stabilization devices and measures, for permanent soil stabilization after construction is completed.
(f) Any modifications to the post-construction storm water runoff controls that occur after initial SWP3 approval requires notification and approval by the City of Stow and Summit County Water Quality.
