Call Meeting to Order Chair Nejedly called the meeting to order at 2:00 p.m. 3. Public Comments - No public comments. 4. Agenda Items a. Receive update and status of preliminary findings regarding the Steam and Aeration Systems Renovations, District Project 7349 Mr. Petit provided a brief overview of the project and the multiple tasks that encompass the project scope. As shown on slide 4, the Condition Assessment task is furthest along since great strides were made when inspections occurred as portions of the plant were taken out of service. Mr. Goel continued with the presentation. He explained that comprehensive assessments were studied to determine the estimated remaining useful life of the assets and a color-coded system was created (slide 7). From an aging asset perspective, the assessments showed that most of the steam system equipment is in the green category (remaining useful life of 20-plus years). The electrical assets had different findings, mainly due to age. As shown on slide 13, some of the transformers are coded orange (or nearing replacement within 5-10 years). These transformers were installed in the 1970s and, with the diligence of the Maintenance group, the transformers have remained operational and useful life remains after many years of service. It was added that the MCCs (motor control centers) are challenging to take offline and further evaluation will need to continue. Member Pilecki praised the condition assessment work, stating it is information he wants to know and see in order to make decisions. He added that this information provides him with the understanding of what needs to be done and when. Chair Nejedly commented that these assessments are time-consuming and costly, and that onsite staff is already aware of the condition of equipment. He opined that a lot of time and money is spent talking about these matters rather than fixing the problems. Critical components should be monitored and fixed as required, preferably long before they fail; information that staff working on the equipment should already know. He stated he does not want to see the District doing study after study with multiple consultants when staff is well versed on these matters. COMMITTEE ACTION: Received the information and provided input to staff.

Receive report on Fiscal Year 2019-20 Closeout of Capital Improvement Projects Mr. Lopez reviewed the materials included with the agenda packet. In a recap of the total expenditures of these closed projects, he noted that this year he added a new underrun/overrun column as compared to the budget. Overall, for sixteen capital projects closed this fiscal year, the aggregate underrun was more than $824,000. He continued with an overview of the slides of individual projects that were over$1 million. Member Pilecki asked whether the replacement of the Solids Conditioning Building roof was coordinated with the upcoming Solids Handling Facility Improvements project (Solids Handling). Mr. Lopez replied that some of the walls will be modified during the Solids Handling construction that may impact the roof; however, the new membrane type roof can be easily repaired. He added that although the new roof may be touched in some areas during the Solids Handling project, the roof replacement could not wait any longer, especially since some leaks were directly over electrical equipment. Mr. Lopez and Mr. Mestetsky replied to an inquiry from Member Pilecki about the work associated to replacing a collapsed slip-liner(a method used to continuously line an existing pipe) inside a 30-inch pipeline (slide 15). It was explained that pressured groundwater attributed to the failure of the collapsed liner, some of which folded, that had been installed approximately in the 1980s and was part of a pipeline acquired from another agency. The liner was too thin (early technology) and the pipe, which runs down a hill, was corroded. Mr. Lopez said that part of this replacement also included filling in the angular spaces within the pipe to resolve any future problems on this gravity line. Each project was reviewed; however, the following were of specific note: 1. As part of the Plant Energy Optimization project (slide 4), Mr. Lopez advised that the District has benefited from a payback of just under three years. 2. The Piping Renovations series of projects approximately began in the year 2000; staff just completed Phase 9. These project phases have been a great learning tool for the engineers as they are designing these projects in-house rather than being consultant driven, except for any specialty work that may be part of a phase. 3. As it pertains to the Collection System easement and aerial crossing work, the pictures show a small glimpse of the challenging work that can be associated with pipes located within backyards, on hillsides, September 18, 2020 Special Board Meeting Agenda Packet- Page 144 of 154 Page 5 of 5 Engineering & Operations Committee Minutes September 1, 2020 Page 4 etc., as well as the necessary coordination with residents, which has been even more challenging during the pandemic. The Committee commended the work on the projects. Chair Nejedly added that the District receives very few complaints, which shows the good work that goes into completing these sewer renovations projects. COMMITTEE ACTION: Received the report. 5. Announcements - None. 6. Suggestions for Future Agenda Items a. Receive list of upcoming agenda items and provide suggestions for any other future agenda items Earlier this year, the Board unanimously voted to delay the establishment of a pilot Septic-to-Sewer Financing Program due to uncertainties of the pandemic and the timing to launch a pilot program. As some time has elapsed, the Committee requested that the topic once again be presented to the full Board for consideration. COMMITTEE ACTION: Received the list and provided input to staff. 7.
