AI Contract Overview

The City of Brentwood is implementing the Wastewater Treatment Plant (WWTP) Phase II Expansion Project to increase treatment capacity from 5 million to 7.5 million gallons per day average dry weather flow. The project focuses on the installation of a Biosolids Drying and Pyrolysis System (BDPS) to produce biochar and Class A biosolids. While initial plans considered using an adjacent vacant parcel, the project has been refined to locate all equipment within the existing WWTP site at 2201 Elkins Way, Brentwood, California. This consolidation eliminates the need for tree removal and new fencing while reducing offsite hauling trips. The project is governed by the California Environmental Quality Act (CEQA), with a history of environmental reviews including an initial Mitigated Negative Declaration in 2016, a Supplemental MND in 2023, and a final project approval on December 9, 2025. Compliance is maintained through specific mitigation measures for noise, water quality, air quality, and biological resources. The project is managed by the City of Brentwood Public Works Department, with Casey Wichert serving as the primary point of contact. The resulting biochar will be packaged in bags for use in city parks or for offsite sale.

Full Description

The City of Brentwood (City) initiated planning for the Wastewater Treatment Plant (WWTP) Phase II Expansion Project in 2016 to expand the treatment capacity from 5 million gallons per day (MGD) average dry weather flow (ADWF) to 7.5 MGD ADWF. As originally proposed, the project included construction of a biosolids dryer building, storage silo, and stockpile area as a means of producing and storing Class A biosolids, thus facilitating additional uses and disposal methods for the biosolids. In 2016, the City prepared an Initial Study (IS) to evaluate potential environmental impacts from construction and operation of the project and adopted a Mitigated Negative Declaration (MND) on August 9, 2016. In 2023, the City modified the project to include a different technology for drying the biosolids and added a pyrolysis system, both proposed to be located on a vacant City-owned parcel adjacent to and east of the WWTP. The City prepared a Supplemental IS to address the change in the project and adopted a Supplemental MND on November 14, 2023. The City has further refined the project and now plans to install the biosolids dryers and pyrolysis system (BDPS) within the existing WWTP site. No project components would be located on the City-owned vacant parcel to the east of the WWTP.
