- Environmental impact/permitting
The Clean Water Program will have a positive impact on our environment by preventing raw sewage from overflowing into San Francisco Bay. As with most infrastructure improvements there are some temporary nuisance impacts during construction and changes associated with building new facilities. The Programmatic Environmental Impact Report (PEIR) describes the improvements and anticipated impacts that could occur from implementing this program.
Final Programmatic Environmental Impact Report
The City conducted a full review of the Clean Water Program through a Programmatic Environmental Impact Report (PEIR) in 2015/2016.
The Public Works Commission received public comments on the Final PEIR and made a recommendation to the San Mateo City Council regarding certification and adoption of the Final PEIR at the May 11, 2016 Public Works Commission Meeting. A summary of the comments received with responses is available here.
The San Mateo City Council certified and adopted the Final PEIR; approved the Underground Flow Equalization System Alternative (formerly called the In-System Storage Alternative) for the Clean Water Program; and adopted required findings, a statement of overriding considerations, and the mitigation monitoring or reporting program at the June 6, 2016 City Council meeting.

Addendum to the San Mateo Clean Water Program Final Programmatic Environmental Impact Report
Since the certification of the Final PEIR, the detailed design of the wastewater treatment plant (WWTP) has progressed.
To evaluate whether the changes to the WWTP (since the certification of the Final PEIR) could require the preparation of a subsequent or supplemental environmental impact report, the more detailed project was compared to the original project evaluated in the Final PEIR. The key changes to the project consist of slightly different locations for the various project components.
Under CEQA, if the criteria requiring the preparation of subsequent or supplemental environmental impact report are not met, then an addendum is considered to be the appropriate document. The purpose of an addendum is to update the analysis in the original EIR when there are minor project changes (in this case, the specific locations of the project components on the site).
