Herberg, General Manager Originator: Ed Torres, Director of Operations and Maintenance SUBJECT: QUARTERLY ODOR COMPLAINT REPORT GENERAL MANAGER'S RECOMMENDATION Receive and file the Fiscal Year 2016/17 First Quarter Odor Complaint Summary. BACKGROUND During the first quarter of FY 2016/17, Plant No. 1 had five odor complaints, Plant No. 2 had five odor complaints, and the collections system had seven odor complaints attributable to the Orange County Sanitation District. A brief summary of the odor complaints, with a table tracking the history, is included as an attachment. RELEVANT STANDARDS • Zero odor incidents/events under normal operating conditions for Plants 1 and 2 • Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting • 12 or fewer odor complaints per year under normal operating conditions in the collections system ATTACHMENT The following attachment is included in hard copy and may also be viewed on-line at the OCSD website (www.ocsd.coml with the complete agenda package: • Fiscal Year 2016/17 First Quarter Odor Complaint Summary Page 1 of 1 Orange County Sanitation District Odor Complaint Report Fiscal Year 2016/17 — 1S1 Quarter 1. Plant No. 1 Treatment Facility Odor Complaint Summary During the 1"quarter, Plant No. 1 received five attributable odor complaints. Three odor complaints were plant odors from the trickling filters. Operations staff increased trickling filter recirculation ratio to minimize the odor. The source of the remaining two complaints were not detected; however, based on the wind direction, staff concluded that the complaints were attributed to OCSD. After each complaint, staff made the necessary plant odor circuits and follow up visits and phone calls to the complainants to better address and identify the odor sources. 2. Plant No. 2 Treatment Facility Odor Complaint Summary Plant No. 2 received five attributable odor complaints during the 1s' quarter. The complaints were attributed to primary influent metering structure, trickling filters, and primary basins flow capacity test. An extra primary scrubber was put in service to minimize the odors.After each complaint, OCSD staff worked closely with the resident and completed odor circuit around the neighborhood to identify and minimize the nuisance odors. 3. Collection Facilities Odor Complaints— 18 Quarter FY 2016/17 Seven attributable odor complaints were received from the collection system during the 1" quarter. Four complaints were attributed to sewer lines due to inadequate manhole seals. Two complaints were caused by OCSD construction projects, and the remaining one was traced to OCSD Pump Station in Rossmoor. In-depth investigations were performed into odor problems reported by residents in Costa Mesa and Yorba Linda. These efforts involved coordination and assistance of City officials and OCSD's Source Control and Collections Division to resolve complex causes. Staff received appreciation from residents in Newport Beach and Yorba Linda for collection system odor abatement efforts. The residents were appreciative of the on-going efforts and professionalism of OCSD staff in identifying and working on the odor problems until resolved. 4. All Odor Complaints Tracking 1.'

Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: CENGEN HOT WATER PIPE BRACING AT PLANT 1, PROJECT NO. FE15-09 GENERAL MANAGER'S RECOMMENDATION A. Approve a Task Order with Dudek, FE15-00-01-02, to provide engineering design services for the CenGen Hot Water Pipe Bracing at Plant 1, Project No. FE15-09, for an amount not to exceed $146,516; and B. Approve a contingency in the amount of$29,303 (20%). BACKGROUND The anaerobic digesters, which are used to stabilize sludge, must be maintained at a minimum temperature of 95 degrees F. The heat is provided by a hot water piping loop that operates at a temperature of 145 degrees F. To accommodate the thermal expansion, the piping requires custom-engineered supports, restraints, and expansion joints. To address a problem with the hot water piping at Digesters 13 and 14 at Reclamation Plant No. 1, the Orange County Sanitation District (Sanitation District) completed Project No. FR11-015 to modify the supports and expansion joints. RELEVANT STANDARDS Protection of Orange County Sanitation District assets PROBLEM Upon completion of FR11-015, the piping was found to expand beyond the acceptable limits for the expansion joints when heated. Upon further evaluation, it was determined that a more detailed approach, including 3-13 computer modeling, is required. PROPOSED SOLUTION The proposed solution is to conduct a more thorough engineering analysis and correct the problem through another construction project. This specialized pipe stress analysis is not within the capabilities of the Sanitation District's staff. Page 1 of 3 TIMING CONCERNS Until the problem is corrected, the expansion joints could fail, which could affect the ability to heat digesters. RAMIFICATIONS OF NOT TAKING ACTION Failure of the joints would result in loss of heat to the digesters, resulting in longer detention times or permit violations. This would also inhibit the production of digester gas,the Sanitation District's renewable fuel supply. In addition, the pipeline removes heat from the Central Generation Engines cooling water by routing it through heat exchangers. Failure of the joints could require shutting down the engines and importing electricity until the repairs could be completed. PRIOR COMMITTEE/BOARD/CONTRACT ACTIONS July 2015 - Approved annual Professional Design Services Agreements (Master Contracts) with Dudek and 11 other firms for professional engineering design and construction support services, Contract No. FE15-00-01, commencing July 1, 2015, with a maximum annual fiscal year contract limitation not to exceed $400,000 for each Master Contract, and up to two additional one-year optional extensions. May 2016 - Amendment No. 1, Contract No. FE15-00-01, extending the contract period until June 30, 2017, was approved by the General Manager. ADDITIONAL INFORMATION Consultant Selection: A Request for Task Order Proposal (RFTOP) was issued to three Consultants in accordance with Ordinance No. OCSD-47 (Purchasing Ordinance). Proposals were received from AECOM and Dudek. RMC Water and Environment declined to propose. Both Proposals were responsive to the RFTOP and staff determined both firms capable of completing the Scope of Work (SOW). Staff selected Dudek as the most qualified to complete the SOW based on the strength of its team. Dudek's individual team members have significant relevant experience with boiler systems and thermal expansion projects. Also, Dudek's proposed subconsultant for thermal expansion modeling has significant experience with high temperature piping analysis. Review of Fee Proposal and Negotiations: Proposals were accompanied by sealed Fee Proposals. In accordance with the Purchasing Ordinance, only the Fee Proposal of the selected firm was opened after concurrence by the Director of Engineering of the recommendation. Staff conducted negotiations with Dudek to clarify the requirements of the SOW, the assumptions used for the estimated level of effort, and the proposed approach to meet the objectives and schedule for the project. Page 2 of 3 Dudek's revised Proposal and Fee Proposal were determined to be fair and reasonable. The estimated level of effort was evaluated in detail for each task and subtask and determined to be justified based on the SOW, the agreed upon assumptions, and the expectation for the quality of services. Based on the above, staff has determined that the final negotiated fee is fair and reasonable for the level of effort required for this project and recommends award of the Task Order to Dudek. CEQA N/A FINANCIAL CONSIDERATIONS This request complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has been budgeted. (Budget FY2016-17 and 2017-18, Section 8, Page 85) and the budget is sufficient for the recommended action.

DUDEK 31879 CAMINO CAPISTRANO.SUITE 200 SAN JUAN CAPISTRANO.CALIFORNIA 93625 T9i9AS0.2525 F949450,2636 September 16, 2016 Larry Roberson Senior Contracts Administrator Orange County Sanitation District 10944 Ellis Avenue Fountain Valley,CA 92708-7018 Subject OCSD FE15-09 CenGen Hot Water Pipe Bracing at Plant 1 - REVISED Dear Mr. Roberson: Pipe stress issues related to thermal expansion and contraction can be a challenging issue to evaluate and remedy. Dudek has assembled a team with the unique qualifications necessary to accurately identify the potential source of pipe failure and design robust long lasting supports that will reduce future risk BACKGROUND AND PROJECT UNDERSTANDING The central generation hot water loop at Plant 1 was constructed in 1994 and consists of 8-inch diameter supply and return pipelines constructed of welded steel.The hot water loop supplies heat to 12 digesters and removes heat from the central generation engines cooling water system. Reliable operation of the hot water loop is critical to the operation of the Central Power Generation Facility. OCSD has identified four out of five newly installed Metraflex expansion joints in their CenGen Hot Water Piping as not properly working,in that they have elongated rather than contracted per their design intent. Upon initial observations, the existing piping system appears to not properly account for the thermal growth of the system and the pressure thrust from the expansion joints. Four of the expansion joints have extended instead of compressing to the point that the unpainted section of the joint is exposed. When expansion joints are used to accommodate thermal expansion, pipe anchors are required to constrain the axial movement and direct it into the expansion joint. The existing piping system appears to use anchors which are not sufficiently robust to adequately constrain axial movement. According to Metraflex, when the expansionjoint has elongated enough to expose an unpainted section of the joint,the internal bellows have failed and require replacement The piping system requires a full thermal stress analysis to identify deficiencies and evaluate reliable long-term improvements. 1.1 PROPOSED WORK APPROACH The Dudek team will perform a site visit to determine locations,type, and sizes of all piping,joints,anchors, guides,etc. and will create a CAD base file of the hot water piping loop.Sub-consultant, Becht Engineering, will then analyze the existing piping system using the pipe stress analysis software, CAESAR R, to determine if, and where, sufficient piping flexibility exists to account for the current displaced positions of the expansion joints. Where the inherent pipe flexibility is not sufficient to accommodate thermal expansion, Becht Engineering will design a support system that meets the requirements American Society of Mechanical Engineers (ASME) code for pressure piping, B31.3 Process Piping, Expansion Joint Manufacturer Association(E)MA)standards, and OCSD's Engineering Design Guidelines. Becht Engineering will determine required locations for expansion joints, anchors, and guides. Becht Engineering will also evaluate if adequately size expansion loops can be used in lieu of expansion joints. w IDUDMCOM Mr. Larry Roberson Subject OCSD FEIS-09 CenGen Hot Water Pipe Bracing at Plant I -REVISED Improving the piping (installing anchors, expansion joints, etc.) in just the area shown in Exhibit 1 of the Request for Proposals, may negatively impact the piping in the remaining portions of the hot water loop piping by limiting flexibility. Therefore, our proposed approach includes analyzing the hot water loop piping within the entire existing limits of constraint,from anchor to anchor. This may require analysis from downstream to upstream equipment connections if adequate anchors do not exist within the hot water piping loop. The Dudek team will prepare a preliminary design report, drawings and specifications in accordance with the recommendations from the pipe stress analysis and design. Dudek will incorporate the construction sequence plan developed during the preliminary engineering phase into the drawings and specifications. Dudek will prepare a Maintenance of Plant Operation specification to specify shutdown durations and constraints and piping improvements and modifications will be designed to minimize pipe disassembly and shutdown. The following defines the proposed work, followed by a design schedule and presentation of the Dudek project team. SCOPE CLARIFICATIONS Dudek has thoroughly reviewed the outline and content items specified in Part 3 and 4 of OCSD's Request for Proposal (RFP) and we acknowledge this as our baseline scope of work. In lieu of repeating those project elements and general requirements,we offer the following scope clarifications. Baseline Survey & Document Collection: It is assumed OCSD will provide CAD basefiles — Dudek will revise and add to the CAD files based on field measurements performed during the initial site visit(s). Dudek will perform a field survey and develop a CAD base file of the existing hot water piping loop within the entire existing limits of constraint, from anchor to anchor. This may require field survey and CAD base file development from downstream to upstream equipment connections if adequate anchors do not exist within the hot water piping loop. Field surrey and CAD base file development of approximately 1,500-feet of hot water piping is assumed. Preliminary Engineering:The pipe thermal stress analysis will be completed using the pipe stress analysis software CAESAR B. Approximately 1,500-feet of hot water piping will be analyzed to verify that improvements to the existing piping (installing anchors, expansion joints, etc.) in the area shown in Exhibit 1 of the Request for Proposals, will not negatively impact the piping in the remaining portions of the hot water loop piping.

Herberg, General Manager Originator: Lorenzo Tyner, Director of Finance and Administrative Services SUBJECT: DOIG DRIVE PROPERTY LEASE EXTENSION GENERAL MANAGER'S RECOMMENDATION Approve the Second Amendment to the Doig Property Lease, to enter into an eight (8) month lease extension of the Orange County Sanitation District's real property at 7311 Doig Drive, Garden Grove, in a form approved by General Counsel. BACKGROUND In 2006, the Sanitation District purchased the property at 7311 Doig Drive in Garden Grove to accommodate the expansion of collection system staffing. However, as a result of the transfer and anticipated transfer of local sewers to local service providers in the Cities of Costa Mesa, Newport Beach, Orange and Tustin and Unincorporated Orange County, it was later determined that this expansion was no longer necessary. Based on the Board's direction and subsequent action declaring the property surplus, staff had negotiated and entering into a five-year agreement to lease the property. The current agreement is set to expire this year. As part of the agreement, the tenant may elect to exercise one five-year option to extend the lease to ten years with annual rate increase of 2%.The tenant has formally requested to exercise the one five-year lease extension. During a review of the property, it was determined that seismic upgrades are required to maintain the property in good order and in compliance with safety codes. Completion of these repairs will be finished after the current lease agreement is set to expire. Therefore, staff and the tenant had mutually agreed to extend the current lease by three months before the tenant elects to exercise their five-year option to extend the agreement. After further investigation of the necessary repairs and time needed for the competitive contracting process, it has been determined that a further extension of the current lease is mutually beneficial to OCSD and the tenant. RELEVANT STANDARDS • Protection of Orange County Sanitation District assets Page 1 of 2 PROBLEM It has been determined that the Doig property requires seismic upgrade work that will not be compete before the current lease expiration date and may compromise some of the tenant's manufacturing operations for a period of time. PROPOSED SOLUTION The lease extension will provide both parties the opportunity to assess the magnitude of the seismic upgrades and work collaboratively on potential lease relief should the work significantly impact the tenant's operations. TIMING CONCERNS Timing is of the essence due to impending repair work and an active lease agreement. RAMIFICATIONS OF NOT TAKING ACTION Current tenant could be adversely affected unless the lease extension is authorized. PRIOR COMMITTEE/BOARD ACTIONS July 2016 - Board of Directors approved First Amendment to extend the lease by three months. December 2011 - Board of Directors authorized the lease at 7311 Doig Drive. November 2010 - Board of Directors declared the property at 7311 Doig Drive as surplus property.

Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: OCEAN OUTFALL SYSTEM REHABILITATION, PROJECT NO. J-117 GENERAL MANAGER'S RECOMMENDATION A. Approve a budget increase of $28,517,000 for Ocean Outfall System Rehabilitation, Project No. J-117, for a total budget amount of$91,000,000; and B. Approve a contingency increase of $2,372,305 (35%) to the Professional Design Services Agreement with Brown and Caldwell for Ocean Outfall System Rehabilitation, Project No. J-117, for a total contingency of$3,050,106 (45%). BACKGROUND The Orange County Sanitation District's (Sanitation District) treated effluent is either delivered to the Groundwater Replenishment System (GWRS)for recycling or is pumped to the ocean through our outfall pipeline. As recycling has increased, the Sanitation District's normal outfall flow has decreased below the minimum outfall pump capacity, requiring construction of a new low flow pump station. In addition, the reclamation of Plant No. 2 effluent will require construction of a new Plant Water Pump Station. The cost of the new Plant Water Pump Station will be reimbursed by the Orange County Water District (OCWD). These pump station changes will also require modifications to the Sanitation District's high voltage electrical system at Plant No. 2. Staff is proposing that the design and construction of the modifications described above be added to the existing Ocean Outfall Rehabilitation Project No. J-117 so that the work can be coordinated and more efficiently delivered. RELEVANT STANDARDS • 24/7/365 treatment plant reliability • Support OCWD expansion of GWRS • Use all practical and effective means for recovering wastewater for reuse PROBLEM The current Plant Water Pump Station does not allow for the separation of reclaimable and non-reclaimable flows. To prevent non-reclaimable plant water from mixing with Page 1 of 4 reclaimable flows being fed to OCWD, a new Plant Water Pump Station, drawing only reclaimable effluent, is required. The Plant Water Pump Station will draw electrical power from the ocean outfall electrical system and will add additional load to the existing standby engine generators. These generators could be overloaded during a wet weather event. An additional engine generator is therefore required to provide standby capacity for the ocean outfall electrical system during a power outage. A portion of the existing buried high voltage lines and existing fiber optic lines (duct banks) interfere with the location of the new GW RS Pump Station. A portion of these duct banks will need to be rerouted to make room for the GWRS Pump Station. The existing high voltage power controls (switchgear) for the major process areas is currently located in a single room. In the event of a fire or a catastrophic failure in the switchgear room due to a short circuit, there would not be sufficient power to feed the ocean outfall pumping systems during a peak wet weather event. PROPOSED SOLUTION The Plant Water Pump Station will be replaced and integrated with the proposed Outfall Low Flow Pump Station using reclaimable effluent. Relocation of the Plant Water Pump Station was included in another project. Staff proposes to move that work from Project No. P2-122 to Project No. J-117 in order to combine construction with the Outfall Low Flow Pump Station. This change will allow a more compact construction site, decreased construction risk, and better pricing. To provide sufficient backup power for these new facilities, an additional 2-megawatt standby engine generator and associated appurtenances will be installed. The new engine generator will increase project costs by approximately $900,000. A portion of the existing high voltage power and fiber optic lines will be relocated. The rerouted lines will increase project costs by approximately$2,900,000. The 30-year-old high voltage switchgear will be replaced and split into two rooms in an existing building. This is needed to avoid a single point of failure and to improve safety. These changes will increase the project costs by approximately $5,800,000. Including this work in Project No. J-117 will provide better flexibility and operability, while simplifying the Contractor's coordination and start-up for all new electrical facilities. The addition of these two changes will increase total project costs by $28,517,000 from $62,483,000 to $91,000,000. These proposed changes will also increase the Consultant's cost for preliminary and final design. Based on typical design costs of 10 to 12 percent of construction costs, staff requests an additional contingency of 35% of the original design budget. Page 2 of 4 TIMING CONCERNS The proposed changes would require changes to the Outfall Low Flow Pump Station design and electrical facilities design, which are scheduled to be completed by the end of the year. In order to incorporate proposed changes, Board approval is needed at this time. RAMIFICATIONS OF NOT TAKING ACTION Not incorporating the Plant Water Pump Station into Ocean Outfall System Rehabilitation, Project No. J-117, would require either delaying construction of the Outfall Low Flow Pump Station; delaying construction of the Headworks Modifications at Plant No. 2 for the GWRS Final Expansion, Project No. P2-122; or changing the location of the Plant Water Pump Station on a separate project. Not incorporating high voltage switchgear modifications at this time would extend the period and risks of catastrophic failure. PRIOR COMMITTEE/BOARD ACTIONS February 2015 - Awarded a Professional Design Services Agreement with Brown & Caldwell to provide engineering design services for the Ocean Outfall System Rehabilitation, Project No. J-117,for an amount not to exceed $6,778,015, and approved a contingency of$677,801 (10%). ADDITIONAL INFORMATION N/A CEQA A Notice of Exemption for Ocean Outfall Rehabilitation, Project No. J-117, was filed and recorded with the County of Orange on April 30, 2014. OCWD is the lead agency and is preparing the CEQA documents for all Final Expansion projects, which include relocation of the Plant Water Pump Station. FINANCIAL CONSIDERATIONS The cost of the replacement of the Plant Water Pump Station was included in approved budget Headworks Modifications at Plant No. 2 for GWRS Final Expansion, Project No. P2-122. Furthermore, OCWD will reimburse the Sanitation District for all costs associated with the Plant Water Pump Station part of the project subject to a new agreement. The cost of the switchgear replacement complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has been budgeted (FY2016-17 and 2017-18, Section 8, Page 55), but the budget is insufficient for the recommended action. The funds Page 3 of 4 will be allocated to the project from the Replacement, Rehabilitation, and Refurbishment line item in the cash flow projections, FY2O16-17 and 2017-18, Section 4, Page 16.
