Read about regulations governing oil refinery fenceline monitoring and view plans and data provided by the five local refineries.

The Air District has disapproved Fenceline Air Monitoring Plans for all five Bay Area refineries because the plans do not meet the requirements of the Air District’s Refining Emissions Tracking Rule. 

The Air District invites written comments on new provisions related to hydrogen sulfide monitoring and quality assurance procedures in revised draft fenceline air monitoring plans for the five Bay Area refineries. Comments must be received by 5 PM Pacific Time on April 20, 2023.
