They also authorized the CEC to determine an acceptable refining margin in the state and penalize companies that exceed it. The agency is currently in the rulemaking process on some of the measures including a requirement for refiners to submit "resupply plans" 120 days before planned maintenance that must be approved by the state. Non-compliance could carry a civil penalty of $100,000-$1mn per day. Separately, the city of Benicia recently approved a safety ordinance that applies to industrial facilities that handle hazardous materials including the Valero refinery. The ordinance included new air quality monitoring programs. California air regulators in October 2024 levied an $82mn fine against Valero for emissions violations at the Benicia refinery. The Bay Area Air Quality Management District and California Air Resources Board announced the penalty for "egregious emissions violations" stemming from a 2019 inspection that discovered unreported emissions coming from the refinery's hydrogen system.
