SALT LAKE CITY (AP) -- Chevron has agreed to pay a $284,000 fine and help buy four clean-running school buses after inspectors found pollution law violations at a Salt Lake City refinery.
The Environmental Protection Agency announced the settlement with the company Wednesday.
Inspectors say the refinery's equipment was producing higher levels of nitrogen oxide, which contributes to acid rain and the destruction of ecosystems.
The agreement calls for Chevron to install pollution controls on three engines at the refinery. That change is expected to reduce nitrogen oxide emissions by an estimated 50 tons per year.
The company also will help buy four compressed natural gas-powered school buses for the Jordan School District. Those buses are expected to conserve more than 6,000 gallons of diesel fuel each year.
