The Master Plan implements the Board-approved Level of Service goals from the OCSD Strategic Plan. 1.2 Document Organization This Master Plan is presented in five volumes, organized as follows: Name Description Volume 1 - Summary Includes the Table of Contents, Executive Summary, and Project Summary. Volume 2 - Treatment Plants Provides a detailed evaluation of the facilities at Plant No. 1 in Fountain Valley, Plant No. 2 in Huntington Beach, and the North County Yard. Volume 3 - Collections System Provides updated information to the 2006 Collections System Model and Strategic Plan Update. Volume 4 - Air Quality, Stormwater, and Biosolids Management Describes air quality, odor control, stormwater management, and biosolids management for the treatment plants and the collections system. Volume 5 - Recommendations Includes the cash flow summary, project list, project description sheets, issue list, and issue descriptions. 1.3 OCSD Overview OCSD is a regional wastewater agency serving 2.5 million people in central and north Orange County, California. The 25-member Board of Directors is comprised of one representative from each of the 21 cities and 3 special districts in the service area, and one representative from the County Board of Supervisors. The annual influent flow of 211 million gallons per day (mgd) comes primarily from 11 sewer sheds within the 479-mile service area. OCSD also receives flow from the Santa Ana Watershed Project Authority (SAWPA) and the Irvine Ranch Water District (IRWD), and treats urban runoff from within the service area. Treated wastewater is a major reclamation source in Orange County. The Orange County Water District (OCWD) Groundwater Recharge System (GWRS) treats OCSD effluent to drinking water standards for groundwater recharge and irrigation uses. It is the largest 1.0 0BEXECUTIVE SUMMARY 1-2 ES110509183641SCO/V1_COMBINED_111709/093180003 advanced water purification facility of its kind in the world, serving as a model for global water recycling. 1.4 History Previous OCSD planning efforts included the 1989 Master Plan and the 1999 Strategic Plan. A 2002 Strategic Plan Update was prepared to address the following issues that developed after the 1999 Strategic Plan. • Bacterial contamination along the Huntington Beach shoreline. • Wastewater flows being lower than previously projected. • Finalization of the OCWD GWRS design. • Urban runoff treatment needs. • Bans on the land application of Class “B” biosolids. • Preparation for renewal of the Ocean Permit. Prior to 2002, OCSD discharged a blend of both primary and secondary effluent into the ocean in accordance with a Clean Water Act (CWA) section 301(h) variance. On July 17, 2002, the OCSD Board of Directors decided to withdraw the variance and achieve federal secondary treatment standards for all ocean discharges. The capital improvements resulting from this decision and a commitment to increase reclamation initiated a significant expansion effort. The majority of that work will be completed in 2012. A primary focus of this 2009 Master Plan was to capture the impact of those changes, and to plan for the years following the completion of the current expansion effort. 1.5 In-House Effort The Master Plan was prepared as an internal effort, using staff from various departments. This highly successful approach provided the following benefits: • Efficiency: Eliminated staff costs to interface with consultant. • Flexibility: Without the limitation of the consulting contract, there was more flexibility to make beneficial scope of work adjustments throughout the process. • Knowledge Retention: Staff retained the knowledge gained in the process. • Future Direction: Staff involvement in the Master Plan provided a mutual understanding of the ongoing issues, a sense of ownership, and a shared vision for the Capital Improvement Program. 1.6 Planning Assumptions The future influent flow rate is projected to gradually increase approximately 20 percent from 2005 through 2030. The main factors that may affect the future flow rate include population increases, a return to normal rainfall, increased urban runoff treatment, and increased upstream reclamation. 1.0 0BEXECUTIVE SUMMARY ES110509183641SCO/V1_COMBINED_111709/093180003 1-3 1.7 Collections System 1.7.1 Pipelines The 2006 Strategic Plan Update (2006 SPU) model identified hydraulic capacity concerns in the regional collections system. The 2009 Master Plan further evaluated those concerns. It determined that some concerns were less critical than previously believed, and that projects to address those concerns should be delayed. These recommendations are shown in Table ES-1.

Preliminary findings indicate that many pipelines will require rehabilitation in the near future. 1.7.2 Pump Stations Pump station and force main capacity needs identified by the 2006 SPU were addressed by CIP projects, many of which are either in construction or have been completed. Many pump stations have recently been rehabilitated, replaced, or abandoned. The Master Plan recommendations for the remaining pump stations address condition and code compliance concerns. 1.8 Treatment Plant Facilities As mentioned above, the treatment plants are currently in a period of expansion to increase reclamation and provide higher levels of treatment. Much of this work will be completed by 2012. The primary need in the near future will be to rehabilitate aging infrastructure. Electrical safety and reliability improvements, and gas compressor rehabilitation are high priorities at 1.0 0BEXECUTIVE SUMMARY 1-4 ES110509183641SCO/V1_COMBINED_111709/093180003 both plants. Improvements to the supervisory control and data acquisition (SCADA) systems are needed to address obsolescence and capacity limitations. The Plant No. 1 headworks facility will need major rehabilitation. 1.9 Recommendations The 2009 Master Plan effort produced a list of over 100 issues related to meeting future demands, regulatory and policy requirements, rehabilitation needs, and efficiency opportunities. Many of these issues were developed into CIP project recommendations. Due to the current expansion efforts, funding for projects identified by the Master Plan will not be available until after 2012. The cash flow chart in Figure ES-1 shows a gradual increase in spending after 2012. The projects in the initial years will primarily focus on the higher-priority rehabilitation needs. The projects planned for future years are associated with the capacity needs projected for future years. FIGURE ES-1 Capital Improvement Project Cash Flow The capital improvement projects recommended by the Master Plan are listed in Table ES-2. In addition to the capital improvements, various focused studies are needed to clarify other issues that were identified. These studies are listed in Table ES-3. A detailed description of each project recommendation is provided in the Master Plan “Recommendations” (Volume 5). 1.0 0BEXECUTIVE SUMMARY ES110509183641SCO/V1_COMBINED_111709/093180003 1-5 TABLE ES-2 Recommended Capital Improvement Projects Project Number Name Year Budget 030101 Cypress and NH Placentia Trunks 2020 66,696,574 030102 Seal Beach PS Rehab 2014 14,023,711 030103 Edinger PS Rehab 2014 11,473,945 030104 Bay Bridge PS Rehab 2015 46,851,942 030105 Crystal Cove PS Rehab 2017 7,379,181 030106 MacArthur PS Rehab 2016 7,027,791 030107 Abandon Yorba Linda PS 2020 9,567,403 030108 Lido PS pump replacement 2014 1,291,845 030109 Coyote Hills Golf Course Chem Station 2020 8,610,663 040501 Plant 2, Headworks Cable Tray 2017 * 040502 Plant 1, Headworks Expansion 2025 222,805,742 040602 Plant 1, Primary Treatment, Cable Tray, Odor Ctrl 2016 33,186,816 040701 Plant 1, Secondary Treatment, Cable Tray 2017 * 040703 Plant 2, Secondary Treatment, Cable Tray 2017 * 040802 Plant 1 Flare Addition 2013 2,179,744 040803 Plant 1 Gas Compressor Rehabilitation 2017 28,386,578 040804 Plant 2 Gas Compressor Rehabilitation 2013 23,353,708 040805 Plant 2 Dig.
