Re: Operation of Emergency Standby Generators at 301 Mentor Drive

En Español

Google, LLC has applied to the Santa Barbara County Air Pollution Control District (District) to increase the permitted daily hours of operation for eight Emergency/Standby Diesel Generators at 301 Mentor Drive in Santa Barbara. The engines are used to provide backup power to their facility during emergency events. The engines are currently permitted to a maximum of 2 hours/day of operation, but this permitting action will increase that allowance to 4 hours/day to accommodate annual load testing requirements. You are receiving this notice because the engines are within 1,000 feet of the property boundary of St. Raphael School.

As part of the District’s evaluation of this proposed modification, we have assessed the potential health risk created by the project’s emissions. Our analysis, which is conservatively health protective, shows that the expected emissions from the proposed permitting action will be below any levels that would create a significant air toxic risk to public health and the environment. Before our agency issues this permit, state law requires that we notify you, since you are either the parent/guardian of a student attending one of the schools or are a resident or business located within 1,000 feet of the site. We are providing you an opportunity to review and comment on this proposed permitting action. Further, prior to issuing the final permit, we will submit to the permit’s administrative file our written responses to any comments we receive during the comment period.

A copy of the draft permit document (Authority to Construct/Permit to Operate Modification 16106-02) is available for review on the District website.
