CITY OF SAN MATEO
RESOLUTION NO. ____ (2025)
APPROVING AN ALTERNATIVE PURCHASING PROCEDURE FOR AN AGREEMENT WITH BRISTOLA, LLC FOR THE WASTEWATER TREATMENT PLANT DIGESTER 2 CLEANING
WHEREAS, the Wastewater Treatment Plant (WWTP) Digester 2 Cleaning Project (Project) is a Clean Water Program capital improvement project that will result in ensuring the reliability and safe operation of existing WWTP facilities; and
WHEREAS, one of the two digesters used to break down solids in the wastewater treatment process, Digester 2, requires cleaning services prior to completion of needed repairs and reinstallation of the mixer and draft tube, which is estimated to be completed in April 2025; and WHEREAS, Digester 2 is egg-shaped, which is uncommon in the Bay Area and few companies have the capability to provide the requisite cleaning services; and WHEREAS, utilizing a sealed bid process will not likely allow for Digester 2 to be cleaned prior to reinstallation of the mixer and draft tube in April 2025; and WHEREAS, San Mateo Municipal Code section 3.60.070(h)(3) provides that the City may use purchasing procedures approved by the City Council if the City Council makes a finding concurrent with the award for the contract that the procedures are in the best interest of the City for the particular contract; and WHEREAS, in lieu of a sealed bid process, three requests for quotes were directly solicited and two companies with the experience and capability to clean egg-shaped digesters submitted quotes; and WHEREAS, staff reviewed the two received quotes and determined that Bristola, LLC is the most competitive and qualified contractor to perform the requisite cleaning services; and WHEREAS, having Digester 2 completed in a timely manner will also allow for the City to have Digester 1 inspected for the WWTP Biosolids and Biogas Evaluation.
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF SAN MATEO, CALIFORNIA, HEREBY RESOLVES that:
1. The Council action approving this agreement is categorically exempt from CEQA review as an “existing facility,” in that it consists of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use. (CEQA Guidelines Section 15301.)
2. In accordance with Municipal Code Section 3.60.070(h)(3), award of an agreement to Bristola, LLC for Digester 2 cleaning services is in the best interest of the City because:
a. The City’s egg-shaped digesters at the WWTP are uncommon in the Bay Area; 1 1
2 8
6 b. Limited companies are capable of cleaning egg-shaped digesters given their specialized nature and specific methods to access and clean;
c. Cleaning and installation of the mixer and draft tube for Digester 2 in a timely manner will minimize ongoing disposal costs, and will allow for Digester 2 to come back online, allowing for Digester 1 to be inspected for the WWTP Biosolids and Biogas evaluation; and d. Bristola is the only company offering an economically feasible method for the cleaning service which meets the City’s timeline.
3. The Agreement with Bristola, LLC for the Wastewater Treatment Plant Digester 2 Cleaning in the amount not to exceed of $364,100 is approved.
4. A contingency reserve of $36,000 is established for this project.
5. The Public Works Director is authorized to execute the agreement in substantially the form presented and approve any necessary change orders within the approved contingency amount.
