City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 Table Number Table 2-1 Table 4-5 Figure 4-3 Table 5-3 Figure 5-1 Table 5-5 Table 4-12 - 3 Executive Summary The City of Oakland’s Consent Decree for operation and maintenance of its Sewer Collection System was approved by state and federal regulatory agencies with an Effective Date of September 22, 2014. The City is pleased to submit this Annual Report as required by the Consent Decree (CD) for Fiscal Year 2016-17 (July 1, 2016 to June 30, 2017). The City of Oakland is in overall compliance with the Consent Decree. The cumulative sewer rehabilitation work is significantly ahead of schedule and the City’s sewer budget, staffing, and equipment have increased this Fiscal Year. It is the City’s full intent to continue to meet its obligations under the Consent Decree. Sanitary Sewer Overflows (SSO): The City of Oakland’s Sewer Collection System had 83 SSO events during FY 2016-17. This is a 6% reduction compared to the 88 SSO events in FY 2015-16. In FY 2016-17, the total volume reached surface water was 203,560 gallons from 16 SSO events. Asset Management Implementation Program (AMIP): The City has implemented its revised AMIP dated October 31, 2014. Infiltration And Inflow Reduction Work: Sewer Main and Maintenance Hole Rehabilitation. As of June 30, 2017, the City of Oakland has Rehabilitated 322,914 feet (61.2 miles) of Sewer Main. This exceeds the Consent Decree requirement to rehabilitate 221,760 feet (42 miles) by June 30, 2017. As of June 30, 2017, the City of Oakland had Rehabilitated an additional 16,385 feet (3.1 miles) of Sewer Main as shown in Table 4-3. This exceeds the Consent Decree requirement to rehabilitate 15,840 feet (3 miles) by June 30, 2017. The City have included sewer mains rehabilitated from both the capital improvement program and minor repairs performed by City crews. The City’s Sewer Main Rehabilitation Program is ahead of schedule. One maintenance hole was found to be in poor condition in FY 2016-17. This maintenance hole was replaced in December of 2016. There are no outstanding maintenance holes in poor condition identified that needs replacement. Sewer Main and Maintenance Hole Inspection. As of June 30, 2017, 1,911,585 feet (362 miles) of sewer mains have been inspected and assessed using CCTV inspection. This exceeds the Consent Decree requirement to inspect 1,700,160 feet (322 miles) by June 30, 2017. The City of Oakland is in compliance regarding maintenance hole inspections. Between July 1, 2016 and June 30, 2017, 1,704 maintenance hole inspections were performed. City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 4 Development of Regional Standards. The City bases its construction plans and specifications on The “Greenbook”: Standard Specifications for Public Works Construction, a statewide standard for the municipal construction industry. In this reporting period, the City has begun incorporating these Standards in the design of its capital projects. The Defendants have and will continue to discuss the Regional Standards, its effectiveness, and potential revisions and improvements at coordination meetings. EBMUD’s Sewer Lateral education and Outreach Program. The City continues to work with EBMUD in implementation of the program. Sewer Lateral Inspection and Repair. In FY 2016-17, the City finalized 318 building permits which required certificates of occupancy for construction or remodeling permits in excess of $100,000. All 318 building permits received Compliance Certificates issued by EBMUD which met the Consent Decree requirement to limit the number of building permits issued without Compliance Certificates to less than 25 per Fiscal Year. Inflow and Rapid Infiltration Identification and Elimination. The City will continue to work with EBMUD in implementation of the program. On September 29, 2016, EBMUD submitted to the City FY 2015-16 Annual Satellite Notification. The City provided a response on December 16, 2016. EBMUD did not find any linear and non-linear high priority sources. 24 private sources were found. Of those 24, the City has determined one to be a high priority source. The one location was abated within the required twenty-four months of making the designation. SSO Reduction Work: Capacity Assurance. The Consent Decree requires the City to increase sewer capacity in certain locations when sewer flows reach within one foot of the Maintenance Hole rim. In FY 2016-17 the City experienced a total of seven locations that reached within one foot of the Maintenance Hole rim. All flows were contained within the system and no SSO event occurred at any of these six locations. One location was suspected to be capacity related. Six locations were non-capacity related. Acute Defects. • 27 New Acute Defects were found in FY 2016-17. • 16 FY 2016-17 identified Acute Defects were repaired. • 3 FY 2014-15 and 2 FY 2015-16 repaired Acute Defects did not meet the one-year requirement. • 1 FY 2014-15 and 1 FY 2015-16 remains not repaired. The City will continue to work with the private parties to abate the defects. • No Sanitary Sewer Overflows occurred because of delays in Repair of Acute Defects. • The status of each repair pertains to the FY initially identified. Outstanding repairs for each FY will be updated annually until repaired in which the record will be added to the associated repaired reporting. Sewer Main Cleaning. As of June 30, 2017, 4,402,534 unique feet (834 miles) of Sewer Main have been cleaned. This exceeds the Consent Decree requirement of 4,118,400 feet (780 miles). Root Cleaning (Foaming). As of June 30, 2017, the City had root foamed 1,227,132 feet (232.4 miles) of Sewer Mains, which exceeds the Consent Decree requirement of 1,056,000 feet (200 miles). City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 5 On December 9, 2016, the City submitted an evaluation report of the root control program to EPA for review and approval. On February 27, 2017, EPA rejected the City’s proposal to foam 23.4 miles of sewer mains per year and directed to continue treating 50 miles of sewer mains per year as specified in paragraph 92(e) of the Consent Decree. The City requests for a more substantial response and its reconsideration for a conditional approval. Hot Spot Cleaning. As of June 30, 2017, 155 locations were identified as hot spots by staff. Each of these locations was cleaned at least once in FY 2016-17. Fats, Oil and Grease (FOG) Control. In FY 2016-17, 39 SSOs were thought to be associated with FOG. These locations were referred to EBMUD for investigation. Pump Station Renovation. The City is significantly ahead of schedule with its Pump Station Improvement Program. One pump station was completed in 2012. One construction contract which consists of three pump stations begun construction in November 2016. Three more pump stations, in which design has been completed, are scheduled to begin in 2018. The completion of all pump stations will be completed by 2019, three years ahead of schedule. Known Noncompliance with Consent Decree. Paragraph 91 of the Consent Decree provides: “Acute Defects. The City of Oakland shall continue to repair Acute Defects as soon as possible, but no later than within one Year of identification.” 3 FY 2014-15 and 2 FY 2015-16 repaired Acute Defects did not meet the one-year requirement. 1 FY 2014-15 and 1 FY 2015-16 remains not repaired. The City will continue to work with the private parties to abate the defects. In the Consent Decree, the City is required to comply in accordance with the requirement described in Paragraph 85a of the Consent Decree in which “Within 90 Days of identifying a Sewer Lateral as defective the City of Oakland shall notify the affected owner in writing.” 5 notices were sent beyond the 90-day requirement, one of which was repaired. 2 notices were not sent, two of which have been repaired. Assessment of Stipulated Penalties. Paragraph 186 of the Consent Decree: For each SSO that reaches waters of the United States, a stipulated penalty may be assessed as follows, with “gallons” referring to the total size of the overflow, spill or release: In FY 2016-17, the total volume reached surface water was 203,560 gallons from 16 SSO events. Table 2-1 provides the number of SSOs for SSOs totaling in each of the three categories of volume. The total potential assessed stipulated penalty from FY 2014-17 for SSOs Reached Waters of United States is $191,600 as detailed below. The City believes that Stipulated Penalties should not be assessed for the SSO events that reached surface waters. The spills were caused by a variety of reasons such as grease deposits, root intrusion, debris, and heavy storms City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 6 and are considered non-point sources. The City has been meeting the cleaning and rehabilitation goals annually since FY 2014 and have responded quickly to SSOs. A penalty would impact the ability of the City to meet future goals as the rehabilitation costs have significantly increased due to market conditions. If Plaintiffs disagree with this position, the City would appreciate the opportunity to discuss potential penalties and provide additional explanations of its position. Recommended Changes to Required Work. The City proposed to foam 23.4 miles of sewer mains per year instead of the 50 miles of sewer mains per year as specified in paragraph 92(e) of the Consent Decree. City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 7 Section 1. Introduction Paragraph 139 of the Consent Decree (Case Nos.

City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 24 Section 5. SSO Reduction Work Paragraph 167 of the Consent Decree requires: “The City shall summarize its Work to reduce SSOs in its service area in the reporting Fiscal Year.” A summary of the City’s work is described below. 5.1 Capacity Assurance Paragraph 167.a. of the Consent Decree requires that the Annual Report contain: “Capacity Assurance: a description of the activities performed in order to monitor the locations in Paragraph 89(a) during rain events…” During FY 2016-17, the City monitored water levels in Maintenance Holes listed in Paragraph 89(a) of the Consent Decree. The high water level alarm sensors were installed 12” below the rim of the manhole cover. The low water level alarm sensors were installed 17” below the rim of the manhole cover. Table 5-1 provides information required in Paragraph 167a of the Consent Decree. Paragraph 167ai requires the City to show the “highest water level in relation to the Maintenance Hole observed in the reporting Fiscal Year”. Table 5-1 is a cumulative list of all locations that received high water level alarms in FY 2014-15, FY 2015-16, and FY 2016-17. In FY 2016-17 the City experienced a total of seven locations that reached within one foot of the Maintenance Hole rim. All flows were contained within the system and no SSO events have occurred at any of these six locations. One location were suspected to be capacity related. Six locations were non-capacity related. Paragraph 167aii requires the City to identify any “capacity-related SSO or instance of the water level reaching within one (1) foot of the Maintenance Holes rim due to a lack of capacity and whether the event(s) occurred during a rain event that was greater than the December 5, 1952 Storm”. As shown in Table 5-1, high water levels were experienced in six locations that were triggered by the December 11, 2014 storm event. Our analysis shows that the December 11, 2014 storm was a storm event have exceeded the December 5, 1952 storm. This event surpassed a 5-year classification with a full duration classification of a 10-year, 21-hour event. Despite this, and out of an abundance of caution, the City has begun design of upgrades at all locations where high water levels were triggered. A full detail of the City’s progress on the planned upgrades is provided below. Paragraph 167aiii requires the City to provide “a description of all activity the City performed to prevent an SSO from occurring at a location where the City had reason to believe a capacity-related SSO was likely to occur”. Table 5-1 includes a description of maintenance activities performed to prevent SSO’s for each location. City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 25 Paragraph 167aiv requires the City to provide “a description of activities to address locations that do not have sufficient capacity”. Table 5-1 includes a description of maintenance activities performed to prevent SSO’s for each location. In addition, as stated above, the City is proceeding with preparing construction plans for capacity upgrades at all seven (7) locations. This work started FY 2014-15; however, due to the complexity of the project location and encountering physical challenges in the existing field conditions, our project has been delayed. The following is a summary progress report on all seven locations: • • • • • • • San Pablo Avenue at 60th Street – Currently in Construction San Pablo Avenue at 62nd Street - Currently in Construction Grand Avenue and Harrison Street – Currently in Construction Park Blvd and Spruce Street - Design 95% Completed. Construction planned for Spring 2018. East 18th Avenue at 4th Avenue - Construction planned for Fall 2017. Maybelle Avenue and Masterson Street - Currently in Construction Trestle Glen Road at Creek Road – Design 95% Completed. Construction planned for Spring 2018. Furthermore, in FY 2015-16, the City completed a large sewer rehabilitation project downstream of three triggered locations: 27th Avenue & Vernon Street, Grand Ave and Harrison St, and 19th Street and Jackson Street. That project rehabilitated approximately 1,079 linear feet of existing 60” conduit sewer pipes with Centrifugally Cast, Fiberglass-Reinforced, Polymer Mortar (CCFRPM) pipes and applied coating for approximately 342 linear feet of existing 3’x 4’-10” conduit sewer pipes. That project is expected to improve the hydraulic conditions of the sewer system in the downtown area and lower the overall hydraulic gradient line in sewer pipes upstream. Paragraph 167av requires the City to provide “a list of sewer segments improved pursuant to Paragraph 89(b) including the date the capacity was improved, and certification that any improved Sewer Main has sufficient capacity”. There are no activities to report. Paragraph 167avi requires the City to provide “identification of any capacity-related SSOs and the SSO date and location”. In FY 2016-17, no Sanitary Sewer Overflows occurred in any of the Maintenance Holes listed in Paragraph 89(a) of the Consent Decree.

Rain event exceeded 1952 Storm. ** Project 1001173 *** Project 1001173 Task #2 and Task #3 † The following information was not included in FY2015-16’s Annual Report, because of a recent finding. The City re-evaluated the 12/13/2015 trigger event and revised a conclusion that the trigger was not capacity related. The trigger was caused by construction activities on a sewer project downstream between December 7, 1015 and December 17, 2015. The construction activities included a sewer bypass, sewer pipe cleaning, and CIPP preparation setup for a 48" sewer line rehabilitation at San Pablo and West Grand Avenue. The bypass pump was set up between San Pablo Ave and West Grand Ave. Additionally, a sewer relief line was constructed from City Project No. C59310 in 2010 to increase sewer capacity near the intersection of Jackson Street and 19th Street. The project split the sewer flows running north on Jackson Street; diverting a portion of the flow to continue north towards Lakeside Drive. Prior to the construction of these improvements, the sewer manhole 50-904-24 would experience high flow levels during high-intensity rain events. The constructed relief line added an alternative flow path from Jackson Street and 19th Street to the 60” trunk sewer line located on 20th Street to the north. The increased capacity provided by the new relief line have reduced the chance of a sanitary sewer overflow (SSO) at this location. The City have undergone hydraulic analysis to determine the benefit the relief line provides. The City’s hydraulic model was run under two scenarios, (1) without improvements and (2) with the relief line constructed. In both instances a 5yr-7hr design storm was used to evaluate sewer performance during a rainfall event. Under scenario (1), the hydraulic grade line (HGL) rose above the rim elevation at manhole 50-904-24, indicating that a SSO would occur. Under scenario (2), with the relief line constructed, the HGL lowered from 8.38 to 7.63 and below the manhole rim. †† To mitigate the capacity deficiencies in the sewer pipes between Maybell Avenue and Masterson Street, City is currently in construction to upsize the existing 10-inch VCP sewer pipe to 14-inch HDPE pipe along Maybelle Avenue between Masterson Street and MacArthur Boulevard. These improvements substantially reduce the risk of a sanitary sewer overflow during wet-weather. City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 30 ††† To mitigate the capacity deficiencies and correct the sags in the trunk sewer along Trestle Glen Road, the City evaluated several capacity improvement options. Of the scenarios evaluated, the preferred option is to upsize pipes along Trestle Glen Road between Creek Road and Humphrey Place from a 12-inch to 16-inch diameter. Modeling results show these improvements are able contain local sewer flows within the system for the 5-year, 7-hour storm. These improvements substantially reduce the risk of a sanitary sewer overflow during wet-weather. The up-sized lines will allow sufficient relief upstream while not overwhelming the system downstream. 5.2 Post SSO Inspection Paragraph 167.b. of the Consent Decree requires that the Annual Report contain: “Inspections: a statement that Oakland completed CCTV inspections downstream of each SSO location.” During FY 2016-17, the City completed CCTV inspections downstream of each SSO. 5.3 Acute Defects Paragraph 167.c. of the Consent Decree requires that the Annual Report contain: “Acute Defects: a description of the activities to Repair Acute Defects…” Paragraph 91 further provides: “Acute Defects. The City of Oakland shall continue to repair Acute Defects as soon as possible, but no later than within one Year of identification.” Acute Defects are shown in Table 5-3 of Appendix D. Table 5-3 shows location of Acute Defect locations identified after the Consent Decree (July 1, 2014). As shown in Table 5-3, the following is a list of activities related to acute defects. • • • • • • 27 New Acute Defects were found in FY 2016-17. 16 FY 2016-17 identified Acute Defects were repaired. 3 FY 2014-15 and 2 FY 2015-16 repaired Acute Defects did not meet the one-year requirement. 1 FY 2014-15 and 1 FY 2015-16 remains not repaired. The City will continue to work with the private parties to abate the defects. No Sanitary Sewer Overflows occurred because of delays in Repair of Acute Defects. The status of each repair pertains to the FY initially identified. Outstanding repairs for each FY will be updated annually until repaired in which the record will be added to the associated repaired reporting. Between July 1, 2016 and June 30, 2017, the median time to correct an Acute Defect was 105 days.

By June 30, 2014, the City shall have cleaned 1,900,800 feet of Sewer Mains. Beginning July 1, 2014, the City shall clean its remaining Sewer Mains at the rate of 739,200 feet per Fiscal Year on a cumulative basis (i.e., 2,640,000 feet by June 30, 2015; 3,379,200 feet by June 30, 2016; etc.).” As shown in Table 5-4a, 4,402,534 unique feet (834 miles) of Sewer Main have been cleaned.

The pipes that are cleaned more than once in a fiscal year may be the same or different in each fiscal year, and the calculation is specific to each fiscal year. For example, pipe A may have been cleaned twice in FY2014-15 and twice in 2015-16, so its footage are included in each fiscal year’s calculation; whereas pipe B may have been cleaned once in FY 201415 and twice in FY2015-16, so its footage are only included in the FY 2015-16 calculation. The cumulative total would include pipe A only once and pipe B only once, which is why the current cumulative total cannot be calculated as the prior cumulative total plus the total for the current fiscal year.

A summary of the cleaning by Sub-Basin is shown in Figure 5-1 of Appendix E. 5.5 Root Cleaning (Foaming) Paragraph 167.e. of the Consent Decree requires that the Annual Report contain: “Root Cleaning: a description of the activities conducted under Oakland’s root control program, including the feet of Sewer Main treated for root control cumulatively and in each Fiscal Year beginning July 1, 2013.” Paragraph 92.e. further provides: “For the first three Fiscal Years, the City of Oakland shall treat a minimum of 264,000 feet of Sewer Mains per Fiscal Year on a cumulative basis (i.e., 264,000 feet by June 30, 2014; 528,000 feet by June 30, 2015; and 792,000 feet by June 30, 2016.)” The City has been treating sanitary sewer mains to reduce instances of excessive root infiltration. The rootfoaming program uses an herbicide which penetrates root cell walls and causes them to decay and die. This treatment destroys roots that have infiltrated sewer mains that can cause stoppages and damages. From 2011 to 2015, the root-cleaning program selected pipes for treatment based on a non-targeted, basin-wide approach. Beginning in FY 2015-16, the City revised its pipe selection process to more efficiently target pipes and avoid treating pipes known to be clear of roots. Selection of pipes within the system treatment is based primarily on observation of roots from CCTV inspections. Other selection criteria include: 1. Priority is given to pipes within easements. 2. All pipes in a sub-basin are treated if a significant number of pipes are affected by root intrusion as indicated in CCTV inspections. 3. Pipes will not be selected for root foaming if the pipe has been rehabilitated within the last five years. 4. Pipes will not be selected for root foaming if the pipe will be rehabilitated within five years or the pipe resides in the hot spot list. City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 34 As of June 30, 2017, the City had root foamed 1,227,132 feet (232.4 miles) of Sewer Mains, which meets the Consent Decree cumulative requirement. Results of the City’s root-cleaning program are as follows: Table 5-5 Root Control Program Implementation Fiscal Year Mains Assessed Cumulative Total FY 2013-14 304,811’ (57.7 miles) 304,811’ FY 2014-15 352,176’ (66.7 miles) 656,987’ (124.4 miles) 528,000’ (100 miles) FY 2015-16 146,784’ (27.8 miles) 803,771’ (152.2 miles) 792,000’ (150 miles) FY 2016-17 423,361’ (80.2 miles) 1,227,132’ (232.4 miles) 1,056,000’ (200 miles) City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 (57.7 miles) CD Requirement 264,000’ (50 miles) 35 Figure 5-1 contains a location map showing sub-basins root-foamed from 2011 to June 30, 2017. Figure 5-1 Root Foaming Areas City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 36 Paragraph 92.e. further provides: “By December 31, 2016, the City shall submit an evaluation of its root control program to EPA for review and approval. The evaluation shall consider the need to treat additional or fewer Sewer Mains to address results from cleaning and CCTV. The evaluation shall propose refinements to the City’s root control program in order to ensure excessive roots in the Collection System are controlled.” On December 9, 2016, the City submitted an evaluation report of the root control program to EPA for review and approval. On February 27, 2017, EPA rejected the City’s proposal to foam 23.4 miles of sewer mains per year and was directed to continue treating 50 miles of sewer mains per year as specified in paragraph 92(e) of the Consent Decree. On February 28, 2017, the City requested for technical feedback and reconsideration since there was no substantial reasons provided. The City is waiting for the Water Board and EPA to provide a more substantial response and its reconsideration for a conditional approval. The root foam evaluation was datadriven in which 23.4 miles of pipe treatment was derived. It will not be the best use of the sewer service funds for the City to treat pipes that are not needed for the remainder of the Consent Decree. 5.6 Hot Spot Cleaning Paragraph 167.f. of the Consent Decree requires that the Annual Report contain: “Hot Spot Cleaning: description of activities conducted under its hot spot program, including feet of Sewer Main in the hot spot cleaning program and the range of cleaning frequencies for Sewer Main in the hot spot cleaning program;” The Consent Decree changed both the definition of “Hot Spot” and the cleaning requirements. In anticipation of the CD, staff reviewed City records and created a new High Frequency Preventive Maintenance List (Hot Spots) containing both locations having more than one SSO in a three-year period (Hot Spots) and other locations identified by staff. The list now contains 155 locations. Each of these locations was cleaned at least once in FY 2016-17. Table 5-5 of Appendix F contains the new High Priority PM List (as of June 30, 2017). Figure 5-2 contains a map of these locations. The City reviewed its data for risk factors such as pipe age, size, slope and materials of construction, and found no correlation between SSOs and those factors. The hot spot cleaning program contains 116,741 feet (22.11 miles) of Sewer Mains which are cleaned every three (3) to twelve (12) months as shown. Between July 1, 2016 and June 30, 2017, the City’s sewer crews cleaned 340,406 feet (64 miles) of Sewer Mains as part of the hot spot sewer cleaning program.

The City identifies and reports FOG problems to EBMUD. EBMUD investigates and inspects FOG sources and works with food service establishments (FSEs) to correct FOG problems. Non-compliant FSEs are referred to the City for enforcement action. In FY 2016-17, 38 SSOs were thought to be associated with FOG as listed in Table 2-1. These locations were referred to EBMUD for investigation as shown in Table 5-6. EBMUD has not referred any FSEs to the City for enforcement action.

Section 8. Assessment of Stipulated Penalties Paragraph 186 of the Consent Decree: For each SSO that reaches waters of the United States, a stipulated penalty may be assessed as follows, with “gallons” referring to the total size of the overflow, spill or release: In FY 2016-17, the total volume reached surface water was 203,560 gallons from 16 SSO events. Table 2-1 provides the number of SSOs for SSOs totaling in each of the three categories of volume. The total potential assessed stipulated penalty from FY 2014-17 for SSOs Reached Waters of United States is $191,600 as detailed below. Table 8-1 SSOs Reached Waters of United States FY # of SSOs for SSOs totaling Less than 1,000 gallons # of SSOs for SSOs totaling 1,000 to 9,999 gallons FY 2014-15 6 7 2 FY 2015-16 3 0 0 FY 2016-17 4 7 5 Potential Assessed Stipulated Penalty $2,600 $14,000 $175,000 Total Potential Assessed Stipulated Penalty from FY 2014-17 # of SSOs for SSOs totaling 10,000 gallons or more $191,600 Paragraph 172 of the Consent Decree provides: "If the Annual Report documents that any of the obligations subject to stipulated penalties may not have been complied with, and a Defendant takes the position that potentially applicable stipulated penalties should not be assessed, that Defendant may include in the Annual Report an explanation as to why Plaintiffs should forego collecting such penalties; ... " The City believes that Stipulated Penalties should not be assessed for the SSO events that reached surface waters. The spills were caused by a variety of reasons such as grease deposits, root intrusion, debris, and heavy storms City of Oakland Sanitary Sewer Collection System Annual Report, FY 2016-17 42 and are considered non-point sources. The City has been meeting the cleaning and rehabilitation goals annually since FY 2014 and have responded quickly to SSOs. A penalty would impact the ability of the City to meet future goals as the rehabilitation costs have significantly increased due to market conditions. If Plaintiffs disagree with this position, the City would appreciate the opportunity to discuss potential penalties and provide additional explanations of its position. Section 9. Recommended Changes to Required Work The City proposed to foam 23.4 miles of sewer mains per year instead of the 50 miles of sewer mains per year as specified in paragraph 92(e) of the Consent Decree.

Introduction The Port of Oakland (“Port”), established under the City Charter in 1927, is an autonomous department of the City of Oakland (“City”) under the governance of a seven-member Board of Port Commissioners appointed by the mayor of Oakland. The Port manages a container seaport, a passenger/cargo/general aviation airport, and waterfront properties for commercial and recreational purposes. The Port owns, operates and maintains a sanitary sewer collection system which consists of lateral pipes, trunk lines, manholes, lift and ejector stations, triturators, and other sewer appurtenances that delivers sewage to the City’s wastewater collection system and to East Bay Municipal Utility District (“EBMUD”) wastewater interceptors and treatment facilities. The Fiscal Year 2016-17 Sanitary Sewer Collection System Annual Report was prepared at the request of the City of Oakland Public Works Department. The following sections in this report present information pertaining to the following sanitary sewer programs for FY 2016-17 (July 1, 2016 to June 30, 2017):     Annual Report of Sanitary Sewer Overflows (SSOs) Asset Management Implementation Plan Infiltration and Inflow Reduction Work SSO Reduction Work Section 2. Annual Report of Sanitary Sewer Overflows Number and Size of Sanitary Sewer Overflows (“SSOs”) For the reporting period from July 1, 2016 to June 30, 2017, the Port’s sanitary sewer collection system had four (4) SSO events, all of which were reported to California Integrated Water Quality System (CIWQS). Two SSOs were associated with construction activities at the former Oakland Army Base on City’s properties but were reported by the Port. The other two SSOs were located at the Oakland International Airport. The size of the SSO is summarized in Table 1. Table 1.

Causes of SSOs The causes of SSOs during the reporting period were due to infrastructure failures and construction damage. The distribution of SSOs by cause is shown in Table 3. Table 3.

However, the sewage overflow volume increased from 3,530 gallons in FY 2015-16 to 9,535 gallons in FY 2016-17. None of the SSOs reached the surface water body. It is anticipated that the SSOs associated with sewer lift stations would be significantly reduced when the upgrades and improvements at these lift stations are completed in FY 2017-18. Section 3. Asset Management Implementation Plan The Port prepared and submitted the Asset Management Implementation Plan (“AMIP”) in 2012. Many programs set forth in the AMIP to reduce SSOs and infiltration/inflow (“I/I”) are very similar to the required elements in the Sewer System Management Plan (“SSMP”), which was updated in July 2015. The SSMP can be found on the Port of Oakland’s website at: http://www.portofoakland.com/community/environmental-stewardship/programs/ Section 4. 4.1 Infiltration and Inflow Reduction Work Sewer Main and Lateral Repair, Rehabilitation and Replacement FY 2016-17 Sanitary Sewer Pipeline Projects Completed   Completed construction of new gravity and force mains on Maritime Street and Burma Road as part of the former Oakland Army Base redevelopment. Minor spot repairs and lateral replacements throughout the Port areas. FY 2017-18 Sanitary Sewer Pipeline Projects Proposed  4.2 Continue with the sewer main and lateral repair and replacements as part of the Airport Development Plan (e.g., the new International Arrival Building) and in conjunction with tenant improvements and/or new development projects (e.g., Cool Port development). Sewer Main Inspection The Port utilized outside contractors to perform CCTV inspection of sanitary sewer lines within the Port areas. For the reporting period from July 1, 2016 to June 30, 2017, approximately 1.5 miles of sewer mains and laterals at the former Oakland Army Base in the Maritime area were inspected. Section 5. 5.1 SSO Reduction Work Capacity Assurance No capacity improvement is necessary at this time since sewer pipelines within the Port appears to contain sufficient capacity to accommodate existing design flows without exceeding the established capacity criteria. Future development at the Port will be subject to engineering review and evaluation to determine if capacity enhancement is necessary. 5.2 Sewer Main Cleaning The Port utilized outside contractors to clean sanitary sewer lines within the Port areas. For the reporting period, approximately 1.5 miles of sewer line was flushed and/or jetted to remove grease buildups and to prevent potential blockages. In addition, preventive maintenance activities at sewer lift stations and grease interceptors were performed on a routine schedule. 5.3 Pump Station Renovation and Upgrade FY 2016-17 Lift Station Improvement Projects Completed MARITIME  Completed pump repairs at lift stations R18P, R80P.  Replaced hardware and level probe at lift station D06P.  Completed installation of RACO remote alarm monitoring and manual transfer switches for emergency generators at lift stations C07P and C08P. AVIATION  Completed rehabilitation of lift station AP01P.  Replaced compressor at lift station AP02P. FY 2017-18 Lift Station Improvement Projects Proposed MARITIME  Design and construction – Rehabilitation of D09P as part of the construction of the Cool Port development project and rehabilitation of former Oakland Army Base sewer lift station R63P as part of the Shipper Transport Express Phase 2 Improvement. AVIATION  Design – Rehabilitation of lift station AP02P at the Airport.  Upgrade pumps and control systems at lift station AP06P.
