Tesoro Refining & Marketing Company LLC Case Settles for $850,000
Tesoro Refining & Marketing Company LLC failed to accurately report the amount of carbon dioxide emissions from their calciner facility in Wilmington for reporting periods 2013, 2014 and 2015 (California Code of Regulations, title 17, § 95103). The underreporting of emissions was due to a calculation error based from readings from the continuous emission monitoring system that was developed and installed by the previous owner of the calciner facility. The reports remained inaccurate for 1,130 days. Tesoro discovered and disclosed the error to the California Air Resources Board (CARB), and thereafter fully cooperated with CARB’s investigation. To resolve the matter, in April 2019, Tesoro has agreed to pay a penalty of $850,000, $425,000 of which will go to a supplemental environmental project.
