DATED and SIGNED this 6TM day of March, 2000. CITY OF AUBURN CHARLES A. BOOTH MAYOR ATTEST: Danielle E. Daskam, City Clerk APPROVED AS TO FORM: Michael J. Reynolds, City Attorney Resolution No. 3190 January 21, 1999 Page 2 BILATERAL COMPLIANCE AGREEMENT Amendment No. 1 Water System Name: City of Auburn Water System Subject: Compliance with the Lead and Copper Rule, Chapter 246-290-WAC The following compliance agreement is hereby established between the Department of Health (hereafter, Department), and City of Auburn Water System (hereafter, City). The Department and the City agree on the following corrosion control issues, approaches and schedules: 1. Auburn has slightly exceeded the copper action level at the 90th percentfie per the Lead and Copper Rule (1.5 and 1.57 mgfL copper at 90th percentfie compared to standard of 1.3 mg/L copper for medium size systems). 2. The best utility system approach is to adjust the pH of the water in the distribution system to reduce corrosiveness towards copper, and may include other appropriate measures such as replacement of susceptible materials, changes to electrical grounding practices, etc. 3. Corrosion control optimization is realized when the elevated pH levels will have caused the following: Copper levels are reduced and maintained below the action level of 1.3 mg/L at the 90th percentfie (see items 4 and 5 for clarifications); · No significant adverse impacts of the treatment on bacteriological quality in the distribution system; · No significant adverse impacts of the treatment on domestic customer satisfaction (e.g., red water due to disturbances in unlined cast irons); and · No significant adverse impact on commercial and industrial customers, health care facilities, and wastewater facilities. Any significant adverse impacts occurring as a result of corrosion control will be investigated and documented along with possible mitigation measures in a report prepared by the City and submitted to DOH. Exhibit "A", Resolution 3190 1 4. The 90th percentile copper level will be calculated using the original 60 monitoring sites per the Lead and Copper Rule plus an estimated 30 additional monitoring sites in the vicinity of untreated sources. Results of all analyses of samples from all monitoring sites in the system will be evaluated in one sampling pool to determine Lead and Copper Rule Compliance. The limits of the zones surrounding untreated sources are depicted on Exhibit 1. 5. Untreated sources of supply will be sampled within the limits of the zones of influence using the number of connections and the population of the zone and a factor of 2.5 people per connection as a conversion factor as follows: Population Number of Sample Sites <100 5 101--500 10 501--3,300 20 3,301--10,000 40 Sample sites will be selected per the Lead and Copper Rule. Any previous monitoring sites in the untreated zones of influence will be retained and can be used in lieu of a new site. 6. Treatment is anticipated in 4 stages at this time. Source Stage Coal Creek Springs, plus blending of well (#4) 1 Well #2, 6 and 7 1 Well #1 To be determined. Well #4 2. if needed West Hill Springs 3, if needed Wells 5 and 5A (Lakeland Hills) No treatment. Monitoring indicates supply is not corrosive. Wells 3Aand3B To be determined. Future Sources To be determined. 7. Monitoring will be conducted after each stage to determine if optimization is achieved. If optimization is achieved, no further treatment stages are needed. If optimization is not achieved, the City plans to proceed to next stage with Department approval. 8. Schedule for Stage 1. Project Schedule for Stage 1 Date Submit Lead and Copper Compliance Report DOH July July 19, 1995 1, 1995 - Schedule Met Finalized BCA (assumed start) October 7, 1996 Submit 30% Design Reports for Coal Creek and Fulmer October -- 1999 Field to DOH DOH Approval of 30 % Design Reports Pending BCA Amendment No. i March 20,2000 Submit Final Plans and Specifications September 15, 2000 DOH Approval of the Final Plans and Specifications October 12, 2000 Complete Construction of Facilities July 18, 2002 Monitoring Report - 2 Rounds July 17, 2003 Submit Report to Determine ff System is Optimized October 23, 2003 9. If the Lead and Copper Rule is amended or changed, the Department and City will review the changes and their effects on the City, and if needed, will jointly renegotiate this agreement. The City of Auburn agrees to perform the following: Submit a project report and construction documents. In accordance with WAC 246-290-110 and 120 submit for review and approval a project report (Predesign Engineering Report) and construction documents (plans and specifications) for the installation of the corrosion control treatment equipment approved by the Department. Construct corrosion control treatment facilities. Complete the installation of Stage i corrosion control treatment facilities in accordance with Department approved construction documents prior to July 18, 2002. Monitor water quality parameters. Monitor water quality parameters in accordance with Title 40 CFR Chapter I Part 141.87(c), (d), and (e) beginning on July 19, 2002. Monitor tap water quality for lead and copper. Monitor tap .water quality in accordance with Title 40 CFR Chapter I Part 141.86 (d) and complete two six- month monitoring compliance periods prior to July 19, 2003. Well #4. Discharge Well #4 into Reservoir #1 for blending under normal operating procedures. Monthly production records will be kept to document where the water is directed and made available to the Department upon request. Department will allow Well No. 4 to be discharged directly into the distribution system should distribution system pressure drop below 35 psi during an emergency (fire, main break, etc.). Optimization Report. Prepare and submit an optimization report that addresses copper monitoring results, any significant adverse effects that may reasonably be associated with corrosion control, any copper staining incidents that occur in the untreated zones of influence, and any copper staining or corrosion incidents in new construction. The report will document what action the City plans to take to address these occurrences. Further, the optimization report will recommend a pI-I operating range for optimization and will recommend if Stage 2 treatment needs to be implemented. The Department of Health a~rees to: Concur with Optimization. The Department agrees that optimization is achieved, that Auburn will be considered in compliance with the LCR, and that no further stages of implementation will be required when the following conditions are met. · Copper levels are reduced and maintained below the action level of 1.3 mg/L at the 90th percentile (see items 4 and 5 for clarifications); No significant adverse impacts of the treatment on bacteriological quality in the distribution system; · No significant adverse impacts of the treatment on domestic customer satisfaction; and · No significant adverse impact on commercial and industrial customers, health care facilities, and wastewater facilities. The Department will also consider the Optimization Report in determining compliance with the LCR. Defer enforcement. The Department shall not initiate any enforcement actions for violations of the Lead and Copper Rule as long as the conditions of this agreement are being met. Renegotiate agreement. The Department will negotiate the level of activity or the schedules in this agreement if requested by the City. Terminate agreement.
