A detailed listing of elements to be inspected, a description of inspection <br /> procedures and inspection frequency, and sample inspection forms; <br /> 3. A schedule for routine inspection and testing of all pipelines, lift stations, <br /> valves, and other key system components. The inspection/testing program shall <br /> be designed to reveal problems that might lead to accidental spills and ensure <br /> that preventive maintenance is completed; <br /> 4. Provisions for repair or replacement of old,worn out, or defective equipment; <br /> 5. Provisions to minimize the need for manual operation of critical systems and <br /> provide spill alarms or other"fail safe"mechanisms; <br /> 6. The ability to properly manage, operate and maintain, at all times, all parts of <br /> the collection system that the Discharger owns or over which the Discharger has <br /> operational control; <br /> 7. The ability to provide adequate capacity to convey base flows and peak flows <br /> for all parts of the collection system the Discharger owns or over which the <br /> Discharger has operational control; and <br /> 8. How the Discharger will take all feasible steps to stop and mitigate the impact <br /> of sanitary sewer overflows in portions of the collection system the Discharger <br /> owns or over which the Discharger has operational control. <br /> ii. At a minimum, the Overflow Prevention and Response Plan shall contain or <br /> describe the following: <br /> I. Identification of areas of the collection system that historically have overflowed <br /> and an evaluation of the cause of the overflow; <br /> 2.

Maintenance activities may <br /> include pretreatment of wastewater from industrial dischargers who discharge <br /> high concentrations of oil and grease in their wastewater; <br /> 3.
