Coffeyville Resources Refining & Marketing has agreed to pay a civil penalty and install new pollution controls and processes to settle alleged environmental violations at its Kansas refinery.
The settlement announced Tuesday by the Justice Department and the Environmental Protection Agency includes a $970,000 fine. It also requires the Coffeyville refinery to put in $4.25 million in upgraded pollution controls and $6.5 million in operating costs.
Regulators say the improvements are designed to benefit the environment and protect the health of residents living near the facility.
The agreement includes more stringent emission limits and more aggressive leak detection and repair practices.
