Tesoro Corp. to pay $1.1 million penalty

Tesoro Corp. agrees to settle clean-air violations with $1.1 million penalty

Associated Press

SALT LAKE CITY (AP) -- Tesoro Corp. has agreed to pay $1.1 million to settle claims it failed to test or monitor the production of gasoline for harmful pollutants.

The U.S. Environmental Protection Agency says Tesoro violated requirements of the Clean Air Act at oil refineries in Utah, Alaska, North Dakota and Washington state.

Tesoro says it's resolving the problem and takes its environmental obligations seriously. The EPA requires refineries to ensure that gasoline complies with fuel quality and performance standards.

The San Antonio, Texas-based company is being required to submit a plan to ensure it properly tests batches of gasoline at all seven of its western U.S. refineries.
