The Air District will host a public meeting session on Thursday, October 10, regarding a permit application that was filed by Radius Recycling, formerly Schnitzer Steel Products Company. Members of the public are invited to attend to learn about and comment on this permit application.  

The Air District's Board of Directors adopted a bold air quality and climate plan, the 2017 Clean Air Plan, entitled Spare the Air - Cool the Climate (YouTube streaming video), which addresses air quality improvement and greenhouse gas reduction for the nine-county Bay Area region.

In partnership with the Air District, Contra Costa County Board of Supervisors Chair John Gioia sent a letter Friday, June 2, to the U.S. Department of Justice requesting at least 40 percent of the penalty against Tesoro Refining & Marketing Company be used for local health initiatives.

The Air District Board of Directors has adopted amendments to Regulation 9, Rules 4 and 6, to eliminate emissions of nitrogen oxides, or NOx, from residential and commercial natural gas furnaces and water heaters in the Bay Area by requiring new appliances to be zero-NOx. 

The Air District has issued Crown Hill Materials, a concrete facility in Vallejo, a Notice of Violation for operating a concrete batch plant without the required air quality permit. The Air District has also issued a cease-and-desist letter directing the company to stop operating the unpermitted plant.

The Air District will host a public learning session on Tuesday, October 22, virtually via Zoom, regarding adopted rules (“Building Appliance Rules”) impacting nitrogen oxide, or NOx, emissions from natural gas-fired water heating appliances. Members of the public are invited to attend, learn, and ask questions about these rules.

The Air District has issued 18 Notices of Violation to MRC for violations of air quality regulations and/or permit conditions for the February 1 fire. This is an ongoing investigation, and more violations may be issued.

The Air District has reached a settlement with Tesoro Refining & Marketing Company that will significantly enhance air monitoring data transparency, providing more information about air pollutants around its refinery in unincorporated Contra Costa County, near Martinez. The agreement requires Tesoro to take new data access and community engagement actions beyond those required by regulation or permit.

The Air District has awarded $1.18 million grant to the San Ramon Valley Unified School District to replace seven older school buses, five compressed natural gas buses and two diesel buses with zero-emission electric buses and the charging infrastructure to support them. The project will also support the installation of eight DC fast chargers and related infrastructure.
