AGENDA
REPORT
February 21, 2023
RECOMMENDED ACTION:
APPROVE a three year sole-source contract with
Sonoma Technologies, Inc., in an amount not to exceed
$340,046, with a term ending December 31, 2025, to
upgrade the existing Jerome® Hydrogen Sulfide meters
and for continuous monitoring and maintenance of the
data, with a two year renewal option in the amount of
$208,698, for a total not-to-exceed contract limit of
$548,744 – Public Works Department (Daniel Chavarria
510-620-5478/Mary Phelps 510-621-1269).
DISCUSSION:
This contract with Sonoma Technologies, Inc. will provide continued monitoring and warranty services for the two (2) Hydrogen Sulfide meters at the North and South ends of the wastewater treatment plant (WWTP). Sonoma Technologies, Inc. will provide the installation and servicing of the meters for the duration of the contract.
The WWTP is required to monitor hydrogen sulfide emissions as part of an agreement that was reached between the City of Richmond and the Bay Area Air Quality Management District (BAAQMD) in 2011.
Sonoma Technologies was the selected vendor of choice from a piggy-back contract back in 2017. The contract consists of monitoring the Hydrogen Sulfide levels at the north and south ends of the Wastewater Treatment Plant located at 601 Canal Blvd., including maintenance and updates to the website for the City that downloads the data measured at the plant. The information is available to the public via the following website: https://richmondwpcp-h2s.org/.
Sonoma Technologies has performed flawlessly over the past five (5) years and City staff strongly recommends the City ratifying a new sole-source contract for three (3) years with a two (2)- year option to renew the contract. Due to low staffing, there was an oversight that caused the previous contract to expire. Therefore, an After the Fact form has been approved to support the contract term beginning January 1, 2023.
