Call Meeting to Order Chair Williams called the meeting to order at 11:00 a.m. 3. Public Comments No public comments. 4. Items for Committee Recommendation to Board a. Review draft Position Paper to award a construction contract in the amount of $447,000 to Industrial Furnace Co., Inc., the lowest responsive and responsible bidder for the Hearth Replacement, District Project 100009; find that the project is exempt from the California Environmental Quality Act; and authorize up to a 25-percent contingency Mr. Lopez and Mr. Shima provided an overview of the information provided in the agenda materials. Mr. Shima responded to questions posed by Chair Williams. He replied there is no known correlation of Hearth No. 9 work needed in both furnaces, noting it is coincidental as the burn zone is higher up in Hearth Nos. 3 and 4. Moreover, Mr. Shima noted that independent inspections found the durability of the original bricks have not been seen at other facilities. Mr. McDonald added it is amazing to have such recognition for the refractory and steel, especially in such a stressful environment. He estimated more work may be needed within the next 10-15 years. In response to an inquiry of the contingency amount, Mr. Lopez stated the percentage was increased based on the good bids received and the potential that a larger contingency may be needed once the work is underway. Lastly, staff responded to Chair Williams question of this work being aligned with the recently rejected bids for the Solids Handling Facility Improvements (Solids Project). The Hearth Replacement has been in the Capital Improvement Plan for a few years and was not part of the Solids Project plan. Some coordination effort had been made previously,- however, reviously,however, it was always planned to be done separately. COMMITTEE ACTION: Recommended Board approval. October 7, 2021 Regular Board Meeting Agenda Packet- Page 162 of 200 Page 4 of 5 Engineering & Operations Committee Minutes September 21, 2021 Page 3 b. Review draft Position Paper to conduct a public hearing on October 7, 2021 at 1:30 p.m., pursuant to Chapter 9.40 of the District Code, to receive comments on the abandonment of a public sewer located on Lost Valley Drive in Orinda as part of the South Orinda Sewer Renovations, Phase 8, District Project 8461 Mr. Lopez advised that since this agenda posting, a change in terminology for this action had been identified and will updated in the final Position Paper. The term relinquishment has a specific meaning in the District Code, which will not occur in this matter. Rather, the sewer will be abandoned since the line will not be handed over to the residents to maintain separately. He explained there is a current construction project to replace the sewer main in the Lost Valley area. The other sewer in the easement is nearing the end of its useful life. With improved technology now available, it was decided to take the opportunity to update the sewer service in this area that has been a challenge to access and maintain due to the topography in the area. All affected property owners have received notification. Furthermore, Mr. Mestetsky advised that the existing alignment is near a creek and the creek crossing is moving that makes continuing as-is very difficult. Mr. Lopez clarified that once the new sewer is built, private laterals will be redirected to the new sewer and then the existing line will be abandoned; quit claim deeds to the property owners would follow once the project is determined to be complete. Staff discussed the map provided to address Chair Williams'questions. It was determined that staff will provide more clarification of the facilities in the final map to be presented for the public hearing. COMMITTEE ACTION: Recommended Board approval. 5. Other Items a. Receive report on Fiscal Year 2020-21 Closeout of Capital Improvement Projects Chair Williams inquired about the status of the San Ramon Pump Station Diversion Project for the temporary wastewater diversion for the Dublin San Ramon Services District (DSRSD)-East Bay Municipal District (EBMUD) Recycled Water Authority (DERWA). Based on his understanding, Mr. Lopez replied that the project, which involved pipeline and gate installation, is complete. However, DSRSD installed the facilities October 7, 2021 Regular Board Meeting Agenda Packet- Page 163 of 200 Page 5 of 5 Engineering & Operations Committee Minutes September 21, 2021 Page 4 under their own project and contractor. Chair Williams asked whether diversion started this summer; Mr. Lopez replied he would need to confirm and provide a future update. Chair Williams asked about specific project components and his concern of the updated variable frequency drive (VFD) installed in order to allow better flow rates. Mr. Lopez replied that the rehabilitated pump and VFD were part of a decommissioned system, and the VFD was part of a group of equipment that was planned for replacement, which was not done in an earlier project. Mr. Lopez added that no assets were prematurely retired. Update: Mr. Lopez provided an update to the Committee after the meeting via the Secretary of the District. Sewage was diverted this summer, beginning in July and ended September 10. He advised the amount of diverted wastewater during this period (flow and total gallons) is being formulated and will be reviewed by Planning and Operations staff.
