EL DORADO, Kan. (AP) The Environmental Protection Agency has ordered owners of a southeast Kansas oil refinery to investigate contamination that may have affected water in the area.
The EPA’s regional office said this week that it reached a settlement with current and past owners of the Frontier El Dorado refinery in El Dorado. The current owner is Frontier El Dorado Refining. Shell Oil Products US was an earlier owner and is also listed on the settlement.
The EPA says the site is contaminated with several toxic chemicals, including benzene, lead and hexavalent chromium. The agency says those chemicals may have affected groundwater, surface water and soil.
The settlement in part requires Frontier and Shell to submit a report on past waste management practices and determine a final remedy for the facility.
