DISCUSSION: On May 2, 2006, the State Water Resources Control Board issued the general Sewer Waste Discharge Requirements (WDR) to all public sewer collection agencies in California with more than one mile of sewer pipe. The City of Newport Beach, as well as hundreds of other cities and sanitation districts statewide, is subject to the WDR. The WDR mandates specific "Plans" be developed and implemented. Together these Plans constitute the SSMP, which has the overall goal of preventing sewer spills and mitigating their impacts by ensuring proper operation and maintenance of the City's sewer system. One of the major components of the SSMP is the development and implementation of the "Capacity Evaluation and Assurance Plan," which the City's consultant team is completing in conjunction with the update of the Sewer Master Plan. The balance of the Plans will be completed as required by the WDR. The several Plans that were initially completed under the Regional 2002 SSMP will be reviewed and updated to meet the more thorough State WDR requirements. SSMP Plan and Schedule Approval October 23, 2007 Page 2 The attached Plan and Schedule shows the milestones required with due dates per the WDR. The first two elements of the SSMP must be approved by City Council prior to November 2, 2007. The first two milestones contain the following: (i) Goal Development Plan & Schedule (ii) Organization Authorized City representative Titles & Telephone Numbers of staff responsible for the SSMP (Organization Chart) Chain of Communication for reporting SSO's The remaining SSMP elements are being developed and will be due as deliverables over the next two years, with the culmination of plan development coming in May 2009. The City has been proactive with the operations and maintenance of the City's sewer system for the past 20 years. We have been operating under the rescinded plan from the Regional Water Quality Control Board since 2002. The City complied with the 2002 regional order by developing and implementing an SSMP and we will comply with each of the updated Plans associated with the State SSMP. Funding Availability: The City currently funds maintenance and operations in the annual budget as well as funding annual capital improvement projects.
