TASKS FOR PERMIT YEAR 4 (Continued) <br /> Task 3: For outfalls with flow, the City will conduct upstream tracking of the flow. Inspection of the <br /> storm sewer system to track the flow may include the following methods: <br /> - Examining and verifying piping schematics <br /> - Physically tracking the flow through the storm sewer system <br /> - Performing remote inspections using TV cameras <br /> - Conducting dye or smoke tests. <br /> Any of these methods may be more or less suitable depending on prevailing conditions. Field <br /> inspectors may incorporate several methods during investigation of a given confirmed or <br /> highly suspected illicit discharge. <br /> Under certain circumstances, the inspectors may obtain a water sample for laboratory <br /> y p aboratory <br /> analysis. Submittal to a laboratory will provide a more detailed description of chemical <br /> parameters than can be obtained in the field (using the field test kits), and laboratory results <br /> may be necessary as evidence for enforcement purposes should the need arise. Sampling <br /> procedures will be verifiable, repeatable, and consistent among sampling locations. Since the <br /> sample results may be used for enforcement purposes, quality control /quality assurance and <br /> chain -of- custody procedures will be followed. <br /> After the source of an illicit discharge has been identified and confirmed, elimination of the <br /> flow will be pursued. Ordinances prohibiting illicit discharges into the stormwater systems <br /> will allow for enforcement procedures to ensure removal of the illicit connection. See BMP <br /> MON1 regarding enforcement. The industrial monitoring program (BMP MON3) will <br /> provide additional procedures for conducting follow -up inspection of industrial sites and <br /> • enforcing applicable local regulations to ensure the elimination of an illicit discharge at an j <br /> industrial or commercial facility. <br /> MON3 - Industrial Monitoring Program <br /> Task 3: Implement the Industrial Monitoring Plan developed under Task 3. <br /> 191 \TASK6\FINALBMP \FACTSHTS \TASKS 4.PY4 01/04/96 4 <br />
