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.

The Air District is issuing an air quality advisory for Wednesday, July 15, due to smoke from the Mineral Fire that started Monday evening in Fresno County. Smoke from the fire is expected to impact the Bay Area starting tomorrow morning when winds are predicted to shift, bringing smoke into the South Bay and moving north later Wednesday. Smoke will likely remain aloft, resulting in smoky, hazy skies but ground-level air quality is not expected to be impacted. 

The Air District is issuing an air quality advisory for wildfire smoke for Wednesday, September 15. Wildfires across Northern California continue to produce smoke, which is being transported southward towards the Bay Area. As a result, hazy and smoky conditions are predicted on Wednesday, especially for communities in the North Bay. At the surface level, onshore winds are expected to keep air quality in the moderate AQI category. Pollution levels are not expected to exceed federal health standards and no Spare the Air Alert is in effect. 

The Air District is issuing the winter season’s first Spare the Air Alert for tomorrow, Friday, December 15, which bans burning wood, manufactured fire logs or any other solid fuel, both indoors and outdoors. Smoke from increased wood burning combined with light winds and low overnight temperatures is expected to cause unhealthy air quality. High pressure over northern California will act like a lid, trapping smoke at ground level. Offshore winds may also transport air pollution from the Central Valley into the Bay Area. 

The Air District is extending an air quality advisory for wildfire smoke through Sunday, August 15. Smoke from Northern California and Southern Oregon wildfires is expected to continue to impact the Bay Area over the weekend. Smoke is expected to be mostly aloft with intermittent periods of smoke mixing to the surface, particularly at higher elevation locations in the North Bay Mountains, East Bay Hills, Diablo Range, and Coastal Hills. Air quality is not expected to exceed the federal health standard and therefore, no Spare the Air Alert is in effect. 

The Air District is issuing an air quality advisory for wildfire smoke for tomorrow, Monday, August 15. Smoke from the Six Rivers Lightning Complex Fire in Humboldt and Trinity counties is expected to impact the Bay Area tomorrow. Isolated pockets of elevated air pollution levels are possible; however, pollution levels are not expected to exceed the national 24-hour standard. A Spare the Air Alert is not in effect and air quality is not expected to be unhealthy. Smoky, hazy skies may be visible and the smell of smoke may be present tomorrow. 

The Air District has reached a pivotal settlement with Chevron that will significantly enhance air monitoring data transparency, providing more information about air pollutants around the Richmond refinery. The agreement requires Chevron to take new data access and community engagement actions beyond those required by regulation or permit.

The Air District is extending an air quality advisory for wildfire smoke in eastern Contra Costa County through Friday, July 15. 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 during the overnight and early morning hours. 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.
