1 TASKS FOR PERMIT YEAR 2 (Continued) <br /> 1 <br /> 'PUBLIC WORKS MAINTENANCE <br /> MON1 - Strengthen Enforcement for Illicit Connections <br /> I <br /> Task 3: • Implement new enforcement activities. <br /> MON2 - Field Screening for Illicit Discharges <br /> Task 2: • The City of Eugene will conduct a field screening and investigations program aimed at identifying the source, <br /> location, and nature of illegal discharges and illicit connections to it's municipal stormwater system, and <br /> eliminating the flows where appropriate. High priority will be given to investigate those basins with known <br /> pollution problems. Priority levels may change as problems are identified, located, and corrected, or as new <br /> problems are identified in basins that were initially classified as low priority. The following field activities <br /> will be conducted for each outfall where dry weather flows are encountered. <br /> - Photograph the outfall at the point where the discharge enters the water - course or channel. <br /> - Complete a field data sheet which provides general information and a description of the site. <br /> - Estimate the flow rate and velocity of flow from the outfall. <br /> - Record field test results and note the presence of floatables, deposits or sheens on the field data sheet. <br /> - Where additional information is desired, collect a grab sample from the flow and analyze the sample using <br /> a field test kit. <br /> • The Part 2 permit regulations require the co- applicants to propose a schedule for implementing the field . <br /> screening component throughout the initial permit term. Most major outfalls screened in Part 1 will be <br /> further investigated m Part 2. Field screening procedures are designed to reflect a continuously narrowing <br /> process to trace illicit and improper discharges to their source. According to the City's proposed schedule, <br /> field screening may occur as frequently as twice a month during the summer months for the Priority 1 sites to <br /> every other winter and/or upon receipt of a complaint for the Priority 6 sites. The field work will be <br /> conducted according to procedures outlined in the Field Screening and Investigations Manual to be developed <br /> by the City during the first year of the permit period (see Task 1). <br /> Task 3: • For outfalls with flow, the City will conduct upstream tracking of the flow. Inspection of the storm sewer <br /> 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 inspectors may <br /> incorporate several methods during investigation of a given confirmed or highly suspected illicit discharge. <br /> • Under certain circumstances, the inspectors may obtain a water sample for laboratory analysis. Submittal to a <br /> laboratory will provide a more detailed description of chemical parameters than can be obtained in the field <br /> (using the field test kits), and laboratory results may be necessary as evidence for enforcement purposes <br /> should the need arise. Sampling procedures will be verifiable, repeatable, and consistent among sampling <br /> 1 locations. Since the sample results may be used for enforcement purposes, quality control /quality assurance <br /> and chain -of- custody procedures will be followed. <br /> • After the source of an illicit discharge has been identified and confirmed, elimination of the flow will be <br /> 1 pursued. Ordinances prohibiting illicit discharges into the stormwater Systems will allow for enforcement <br /> procedures to ensure removal of the illicit connection. See BMP MON1 regarding enforcement. The <br /> industrial monitoring program (BMP MON3) will provide additional procedures for conducting follow -up <br /> inspection of industrial sites and enforcing applicable local regulations to ensure the elimination of an illicit <br /> discharge at an industrial or commercial facility. <br /> \ 91C0753A\ TASK6 \FINALBMP\FACTSHTS \RESP- PTY.PY2 01/04/96 4 <br />
