Air District settles case with Chevron U.S.A. Inc.

The settlement covers 51 notices of violation issued to the company for non-compliance with air quality regulations during its operations that occurred largely in 2015 and 2016. The violations that led to this settlement were corrected soon after they were discovered.

The notices of violation included:

• Several violations of the federal standard limit the amount of hydrogen sulfide that can be burned at combustion sources
• A public nuisance violation following flaring associated with an unplanned shutdown
• Violation of the opacity standard for smoke associated with flaring
• Three violations of the requirement to monitor fuel flow to furnaces to control nitrogen oxide emissions
• Failure to include certain components in the leak detection and repair program
• Nitrogen oxides exceeded limits established by District permit for furnace emissions
• Failure to monitor during process vessel depressurization

The Air District issues notices of violation when facilities violate a specific air quality regulation or rule. Violators are required to respond to the notice within ten days and submit a description of the actions they will take to correct the problem. These actions can include shutting down certain operations immediately or changing operations or equipment to come into compliance.
