For the past several years, pumping stations has increased its equipment procurement to meet the reliability concerns associated with PG&E's planned or emergency power shutdowns. Several projects have included the procurement of new emergency generators, pumps, and other needed equipment to ensure that the pumping stations can continue to operate in emergency conditions. I n addition, Capital Projects continues to renovate and improve the maintenance serviceability of Central San's pumping stations which has increased spare parts and electrical equipment.

The new facility will include power for lights, equipment plugs, and security. The maintenance division at the treatment plant supports pumping stations and will also use the facility for storage, as needed. Central San staff prepared the plans and specifications for the Project. The Engineer's estimate is $630,000. The project was advertised on November 21 and November 28, 2022. Eleven (11) sealed bids ranging from $550,000 to $1,078,508 were received and publicly opened on December 20, 2022.

A summary of bids received is shown in Attachment 2. Central San will administer the construction contract and provide contract administration, inspection, survey, office engineering, and submittal review. Consultant inspection may be used to supplement staff on an as -needed basis. California Environmental Quality Act (CEQA) Staff has concluded that this project is exempt from CEQA under Central San's CEQA Guidelines Section 15061(b)(3), since it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment. This certainty is based on Central San's past experience with numerous construction projects of this nature on the treatment plant campus; its long familiarity with the project sites; Central San's impact -limiting construction specifications, and the impact - limiting components of the project description. Central San's specifications are standardized general and special conditions that are made part of the project to address environmental considerations, as well as compliance with applicable federal, state, county, district, municipal and local laws, ordinances, orders, and regulations. Approval of this project will establish the Boards independent finding that this project is exempt from CEQA. ALTERNATIVES/CONSIDERATIONS Reject all bids, which is not recommended.
