Chevron Case Settles for $192,500

This page last reviewed March 1, 2013

In January 2013, Chevron paid $192,500 in penalties for supplying more than 15,498,000 gallons of gasoline in violation of California reformulated gasoline regulations.  On November 16, 2009 Enforcement Division staff obtained 6 samples of California Reformulated Blendstock for Oxygen Blending (CARBOB) from six production tanks at Chevron’s Richmond Refinery.  The regulation allows refiners and importers to specify an alternative set of production limits (a “Predictive Model”) for California gasoline.  Analysis of the CARBOB samples collected indicated that the olefin levels in two of the six samples exceeded the predictive model limits.  Staff discovered the issue during routine sampling in northern California.  ARB investigation concluded that the violation was due to an incorrect formula in one cell from a spreadsheet (not password protected) used to calculate and convert the proper percent of olefins.  Chevron took immediate steps to investigate and stated all spreadsheets have been audited, corrected and password protected to prevent any chance of similar recurrence.
