IV. Illicit Discharge Elimination a. Eliminate source of contamination or if nature of the source prohibits elimination, utilize targeted education to inform/minimize the source (e.g. pet waste or pool/spa water disposed in storm sewers: distribute information on proper disposal throughout neighborhood). b. The following timeframes are required for illicit discharge elimination: i. Within twenty-four (24) hours of identification of an illicit discharge that has a reasonable likelihood of adversely affecting human health or the environment, the MS4 Operator must eliminate the illicit discharge; ii. Within five (5) days of identification of an illicit discharge that does not have a reasonable likelihood of adversely affecting human health or the environment, the MS4 Operator must eliminate the illicit discharge; iii. Where elimination of an illicit discharge within the specified timeframes is not possible, the MS4 Operator must notify the Regional Water Engineer. c. Refer to your Stormwater Management Plan (Appendix O) for detailed provisions for escalating enforcement and tracking. Your municipality has a local law specific to illicit discharges to assist with enforcement as needed. V. Documentation The Monitoring Locations Inspection and Sampling Field Sheet completed in the field is to be filed and retained as compliance documentation for inspection and sampling. You may also scan the completed forms. If you opt to scan, create a new folder for each year or indicate year of inspection in the file name (this will be helpful for planning inspections to meet your compliance goal and for state/federal compliance audits). Retain all documentation for 5 years. a. Inspection Frequency (20%/year) i. Completed Monitoring Locations Inspection and Sampling Field Sheets. ii. Record monitoring locations inspected on spreadsheet or whatever you use to track inspections. It doesn’t have to be elaborate, just a tool to identify outfalls inspected and those in need of inspection. e.g. Outfall ID and date inspected are adequate. Additional information such as whether it was flowing and a “Notes” column are also useful. b. Sampling The Monitoring Locations Inspection and Sampling Field Sheet documents both inspection and sampling. c. Track Down and Elimination All steps and actions utilized to track down and eliminate illicit discharges should be carefully documented. There is no “one size fit” as each instance will be unique. Documentation should include all efforts taken to identify and eliminate the source of contamination: how track down was done, results of track down, actions to eliminate source of contamination, additional details, and any enforcement measures utilized.
