The Air District's Board of Directors has adopted two new regulations to further tighten air pollution controls on petroleum operations at Bay Area refineries. Regulation 9, Rule 14 reduces sulfur dioxide emissions from the largest Bay Area source, coke calcining. Regulation 12, Rule 15 is a first-of-its-kind requirement that will better enable the Air District to track refinery emissions as changes are made at the facilities.

It has been reported that companies throughout the Bay Area have received letters dated January 1, 2025, February 1, 2025, and February 14, 2025, with misinformation about the Bay Area Commuter Benefits Program. These letters were not sent by the Bay Area Air District or the Metropolitan Transportation Commission and contain misinformation. Please disregard these letters if you received them. If your company is registered in the Commuter Benefits Program, you can check the Commuter Benefits Program website to verify your company's registration in the system.

The Air District is extending an air quality advisory for wildfire smoke in eastern Contra Costa County through Thursday, July 14. Smoke from the Marsh Fire is expected to continue to impact the eastern Contra Costa cities of Pittsburg, Antioch, Oakley and Brentwood. Onshore winds during the daytime are expected to disperse smoke, but as winds die down overnight localized pollution levels may rise between 10 PM and 9 AM. Pollutant levels are not expected to exceed the national 24-hour health standard. A Spare the Air Alert is not in effect and air quality is expected to be in the moderate range overall. 

The Air District is lifting an air quality advisory for the Bay Area due to wildfire smoke that was originally scheduled to last through today, Monday, July 14. Over the weekend, smoke from the Butler and Green wildfires had been moving down the Sacramento Valley and impacting air quality in portions of the Bay Area. However, as of Monday morning, the Bay Area is experiencing strong onshore winds, and smoke has remained mostly outside of the region. Air quality has been in the Good Air Quality Index category. Moderate onshore winds are expected to continue into Tuesday, keeping the smoke outside of the Bay Area. As the week progresses, these onshore winds will turn southerly in northern California, and this also is expected to keep the smoke from moving towards our region.

The Air District is extending an air quality advisory for the Bay Area due to wildfire smoke from fires in northern Sacramento Valley through Monday, July 14. Smoke from the Butler and Green wildfires is still moving down the Sacramento Valley and is expected to continue to impact air quality in portions of the Bay Area on Sunday and Monday. Areas that are expected to be most impacted will be parts of the North Bay and East Bay and higher elevation locations. Conditions can change rapidly and the amount and location of smoke at ground level is hard to predict. The public can check for real-time smoke pollution levels in their local area with the U.S. EPA’s Fire and Smoke Map.  Smoky, hazy skies may be visible, the smell of smoke is possible and air quality may become unhealthy at times on Sunday and Monday.
