Regulation 12, Rule 11 Flare Monitoring Data Submittals


The refinery flare monitoring data presented on this webpage are based on reports submitted by each refinery to the District on a monthly basis. These monthly reports are submitted 30 days after the end of the month and include monitoring data for each flare subject to the Reg. 12-11 flare monitoring requirements. 

How to read the graphs
One graph is generated from the monitoring data for each flare for each pollutant reported (Methane, Non-methane Hydrocarbon, and Sulfur Dioxide). Pollutant emissions are an estimate based on calculations from direct vent gas flow measurement and do not represent a direct measurement of actual emissions. Each graph plots reported vent gas flow volume to the flare on the left "Y" axis (Standard Cubic Feet) for each day of the month and the estimated pollutant emissions on the right "Y" axis (lbs/day).


NOTE: The reader is strongly encouraged to pay attention to the graph scales as they vary from each individual graph.

Preliminary Program
This information is being provided to the public as part of the District's ongoing commitment to make regulatory programs more informative to the general public. Additional information will be made available as the District continues to improve this program.
