Chevron fined $422,500 for 3 instances of non-compliant fuels in California; ethanol, olefin and cetane issues
19 July 2013
Chevron USA Inc. has paid $422,500 in penalties for supplying gasoline and diesel fuel in violation of California regulations designed to protect air quality. Chevron agreed to pay the penalties as part of three separate settlements it reached with the California Air Resources Board (ARB).
In all, 15.9 million gallons of fuel were in violation of state regulations. In two cases, Chevron disclosed the violations. In the third, ARB enforcement staff discovered the violation as a result of routine fuel sampling.
Details of each of the three cases are as follows:
Chevron paid $205,000 for supplying more than 385,000 gallons of gasoline in violation of California reformulated gasoline regulations between mid-June 2009 and Aug. 1, 2009. Dispensed from Chevron terminals in Sacramento and San Jose, the fuel did not contain adequate amounts of ethanol.
Chevron paid $192,500 for supplying more than 15.5 million gallons of gasoline in violation of California reformulated gasoline regulations. Analysis of gasoline samples indicated olefin levels exceeded certain required specifications.
Higher levels of olefin mean more smog will be formed from tailpipe emissions since hydrocarbons, including olefin, react with sunlight and other pollutants to form smog. Chevron was notified by ARB of the violation, and took immediate steps to find and rectify the cause to prevent future occurrences.
Chevron paid $25,000 in penalties for supplying and selling more than 36,000 gallons of diesel fuel in August 2009 that did not meet a required minimum cetane number. (The cetane number indicates the combustion quality of a diesel fuel, and how likely it is to create excess hydrocarbon emissions. When the cetane number is too low, unburned hydrocarbons, which lead to smog, tend to increase.)
In California, motor vehicles are the main source of smog-forming pollution and diesel exhaust accounts for 70% of Californians’ daily exposure to air toxics. Mobile sources account for nearly 40% of greenhouse gas emissions in California and more than half of the emissions which contribute to ozone, the main ingredient in smog, and particulate matter, tiny particles that can lodge deep in the lungs and increase the risk of health problems.
Chevron gets fined the largest amount for a moderate amount of gasoline....... without ethanol. Yeah, got to keep the miserable ethanol in the breech. If EPA correctly calculated the mpg decrease that ethanol caused to vehicles in the U.S., ethanol would be discontinued. As for the hundreds of thousands of drivers who support the 7000+ stations still dispensing 100% gasoline(ethanol-free) in the U.S. & Canada, they see no need to punish Chevron.
With a decade+ of mpg records for for 3 cars, comparing 100% gasoline to 10% ethanol blends, the cars show 8%, 7% & 5% increase on real gasoline. All engines are quieter, smoother, & have more torque, such that hills are climbed with less downshifting. One car I almost switched to fuel injection to smooth some of its unevenness. However, switching to 100% gasoline made the car smooth.
Using 100% gasoline, a vehicle with a 14gallon tank, will drive like it has a 15gallon tank, without installing the larger tank or carrying the extra gallon, but will travel an extra gallon's worth of distance down the road. For my 2013 Elantra, bad mouthed for poor mpg, I'll travel almost 39 miles further down the road using 100% gasoline.
