EXHIBIT B: NEW CHAPTER 927 to precipitation, stormwater runoff, and snow melt. The SWP3 shall include measures to prevent and respond to chemical spills and leaks. Applicants may also reference the existence of other plans (i.e., Spill Prevention Control and Countermeasure (SPCC) plans, spill control programs, Safety Response Plans, etc.) provided that such plan addresses this requirement and a copy of such plan is maintained on site. (g) 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. (h) 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. Alternatively, sediment may be removed by settling in place or by dewatering into a sump pit, filter bag or comparable practice. Ground water dewatering which does not contain sediment or other pollutants is not required to be treated prior to discharge. However, care must be taken when discharging ground water to ensure that it does not become pollutant -laden by traversing over disturbed soils or other pollutant sources. (i) INTERNAL INSPECTIONS. All controls on the site shall be inspected a at least once every seven calendar days and within 24 hours after any storm event greater than one-half inch of rain per 24 hour period. The inspection frequency may be reduced to at least once every month if the entire site is temporarily stabilized or runoff is unlikely due to weather conditions (e.g., site is covered with snow, ice, or the ground is frozen). A waiver of inspection requirements is available until one month before thawing conditions are expected to result in a discharge if prior written approval has been attained from the City Engineer: i. The project is located in an area where frozen conditions are anticipated to continue for extended periods of time (i.e. more than one (1) month). ii. Land disturbance activities have been suspended, and temporary stabilization is achieved. iii. The beginning date and ending dates of the waiver period are documented in the SWP3. iv. For sites that will not be completed by October 1, a Pre -Winter Stabilization Meeting shall be held by the landowner and the developer, engineer and contractor of the project and the City of North Olmsted prior to October 1, in order to plan and approve winter erosion and sediment controls as defined in the most current online edition of Rainwater and Land Development. The applicant shall assign qualified inspection personnel to conduct these inspections to ensure that the control practices are functional and to evaluate whether the SWP3 is
