Routine sampling on April 5, 2004, found that three tanks of regular CARBOB at Tesoro’s Martinez Refinery had aromatic hydrocarbon contents that exceeded the specification of their respective predictive models. The cause was determined to be incorrect results from Tesoro’s laboratory, so retain samples were analyzed to determine when the laboratory equipment failed, and how many other batches were also in violation in the meantime. The case has been settled $425,000. Of that total, $250,000 cash was paid to the Air Pollution Control Fund, $75,000 cash was paid to the California District Attorneys Association to support their Circuit Prosecutor Project and an environmental trade-off of 5,000 tons of emission reductions is valued at $100,000.
