Exhibit A— Scope of Work Background The City owns and operates a sewer collection system consisting of more than 250 miles of 4- inch through 42-inch sewer piping, 8 siphon locations, and 11 pump stations. The average daily flow is 6.5 million gallons per day. Collected wastewater is treated by the Dublin San Ramon Services District's (DSRSD)wastewater treatment plant, except for the Ruby Hill neighborhood, which is treated by the City of Livermore's wastewater treatment plant. Both treatment plants dispose of the treated wastewater not used for recycled water via the Livermore-Amador Valley Water Management Agency(LAVWMA). The City is an enrolled agency under the State Water Resources Control Board (SWRCB)Order No. 2006-00003-DWG(Statewide General Waste Discharge Requirements for Sanitary Sewer Systems) and Order No. WQ 2013-0058-EXEC (Monitoring and Reporting Program), herein referred to as WDR. As a requirement of the WDR, the City must maintain a Sanitary Sewer Management Plan(SSMP)and perform internal audits of the SSMP to assess the current state of the sewer program and compliance with WDR provisions. The City's last audit covered the period of FYI 8/19 and 19/20 and found that although sewer system overflows were few and of small volume,the development of a more formal operations and maintenance(O&M)program was recommended to improve compliance with the WDR. Based on the recommendations of the last SSMP audit, the City is pursuing the development of a formal O&M program to support the sanitary sewer system. The SWRCB is currently in the process of issuing a new WDR with an estimated effective date of late 2022. It is the City's goal that the O&M program improvements are not only implemented to comply with the current WDR more fully,but also better position the City to address future WDR requirements when they become effective. Scope The consultant shall develop a formal O&M program to support the City's sanitary sewer system as summarized below and further detailed in the not-to-exceed compensation table. Task 1 —Current O&M Program Understanding: The consultant shall review existing information related to the sewer program to understand its status. Task 2—Develop Future O&M Program: The consultant shall develop the framework and procedures for a formal O&M program including establishing O&M related goals and performance indicators; developing cleaning and condition assessment procedures for gravity piping,manholes, and siphons; developing a bad spot program; updating pump station maintenance checklists; developing a sewer pipe Fats, Oils, and Grease(FOG) and blockage control program; and recommend preliminary staffing levels and vehicle/equipment needs to support the program. The developed framework and procedures shall be documented in a Sewer O&M Program Report. Task 3 —Develop Emergency Response Plans (ERPs) and Standard Operating Procedures (SOPS)—The consultant shall develop an overflow emergency response plan that is compliant with the WDR and shall develop emergency response plans for each pump station in the event of a utility power outage. The consultant shall also determine the core competency requirements
