1057.09 PERFORMANCE STANDARDS.
   (a)   The SWP3 must contain a description of the controls appropriate for each construction operation and the applicant must implement such controls. The SWP3 must clearly describe for each major construction activity the appropriate control measures; the general sequence during the construction process under which the measures will be implemented; and the contractor responsible for implementation (e.g., contractor A will clear land and install perimeter controls and contractor B will maintain perimeter controls until final stabilization). The SWP3 shall identify all subcontractors engaged in activities that could impact storm water runoff. The SWP3 shall contain signatures from all of the identified subcontractors indicating that they have been informed and understand their roles and responsibilities in complying with the SWP3.
   (b)   At a minimum, the SWP3 shall include controls and performance measures describing:
      (1)   Non-structural Preservation Measures: The SWP3 must make use of practices that preserve the existing natural condition to the maximum extent practicable.
      (2)   Erosion Control Practices: The SWP3 must make use of erosion controls that are capable of providing cover over disturbed soils. A description of control practices designed to re-stabilize disturbed areas after grading or construction shall be included in the SWP3. The SWP3 must provide specifications for stabilization of all disturbed areas of the site and provide guidance as to which method of stabilization will be employed for any time of the year.
      (3)   Runoff Control Practices. The SWP3 shall incorporate measures that control the flow of runoff from disturbed areas so as to prevent erosion.
      (4)   Sediment Control Practices. The SWP3 shall include a description of, and detailed drawings for, all structural practices that shall store runoff, allowing sediments to settle and/or divert flows away from exposed soils or otherwise limit runoff from exposed areas. Structural practices shall be used to control erosion and trap sediment from a site remaining disturbed for more than 14 days. All sediment control practices must be capable of ponding runoff in order to be considered functional. Earth diversion dikes or channels alone are not considered a sediment control practice unless used in conjunction with a sediment settling pond. Sediment control practices shall be functional throughout the course of earth disturbing activity. Sediment basins and perimeter sediment barriers shall be implemented prior to grading and within seven (7) days from start of grubbing, and shall continue to function until the up slope development area is restabilized.
      (5)   Non-sediment Pollutant Controls: No solid or liquid waste, including building materials, shall be discharged in storm water runoff. The applicant must implement site best management practices to prevent toxic materials, hazardous materials, or other debris from entering water resources or wetlands. These practices shall include but are not limited to the following:
         A.   Waste Materials: A covered Dumpster shall be made available for the proper disposal of garbage, plaster, drywall, grout, gypsum, and other waste materials. Disposal practices for construction demolition and debris (C&DD) wastes shall be outlined in the SWP3.
         B.   Concrete Truck Wash Out: The washing of concrete material into a street, catch basin, or other public facility or natural resource is prohibited. A designated area for concrete washout shall be made available.
         C.   Fuel/Liquid Tank Storage: All fuel/liquid tanks and drums shall be stored in a marked storage area. A dike shall be constructed around this storage area with a minimum capacity equal to 110% of the volume of all containers in the storage area.
         D.   SPCC and/or Fuel Spill: Provisions for a Spill Prevention, Control and Countermeasure (SPCC) plan must be included in the SWP3. Notification requirements in the event of fuel spills less than 25 gallons and in excess of 35 gallons must be included.
         E.   Toxic or Hazardous Waste Disposal: Any toxic or hazardous waste shall be disposed of properly.
         F.   Contaminated Soils Disposal and Runoff. Contaminated soils from redevelopment sites shall be disposed of properly. Runoff from contaminated soils shall not be discharged from the site. Proper permits shall be obtained for development projects on solid waste landfill sites or redevelopment sites.
      (6)   Compliance with Other Requirements. The SWP3 shall be consistent with applicable State and/or local waste disposal, sanitary sewer, or septic system regulations, including provisions prohibiting waste disposal by open burning, and shall provide for the proper disposal of contaminated soils located within the development area.
      (7)   Trench and Ground Water Control. There shall be no sediment-laden or turbid discharges to water resources or wetlands resulting from dewatering activities. If trench or ground water contains sediment, it must pass through a sediment-settling pond or other equally effective sediment control device, prior to being discharged from the construction site. Trench and groundwater control must comply with applicable provisions in the latest version of the Ohio EPA Construction General Permit.
      (8)   The site operator shall maintain current records pertaining to the approval and implementation of the SWP3 on site and make them available for inspection by authorized City or State personnel.
