Valero Refining Company has agreed to pay an additional $3,250,000 penalty for air quality violations related to its now-idled Benicia refinery in a new settlement with the Bay Area Air District announced Tuesday.  

The settlement resolves 118 notices issued by the air pollution regulator for violations that occurred between 2019 and 2023, according to Kristine Roselius, a spokesperson for the Air District. In addition to the penalty, Valero will be required to expand its fenceline air quality monitoring program, and provide public access to and reporting of the monitoring data.

The pollution emitted during that period includes particulate matter, butane and sulfur-related pollutants, Roselius told The Benicia Bridge.  […continued on The Benicia Bridge (including Q&A with spokesperson for the the Air District)…]
