Flare Trends and Data
View more than 10 years of data about flaring from the five Bay Area refineries. See how often and how much gas is flared, and view bar graphs showing emissions from flaring.
Flare Monitoring Data
The graphs in the documents below are based on the monthly reports that each refinery submits to the Air District. The monitoring data for each flare are subject to flare monitoring and reporting requirements(41 Kb PDF, 8 pgs, revised 4/24/2018). Flare data posted to this page is subject to change when new information is obtained by the Air District.
