Edwardsville pipeline leaked an estimated 165,000 gallons of oil. Some flowed into a creek
The Illinois Environmental Protection Agency has asked the Attorney General to enforce cleanup and other action by energy company Marathon Pipe Line after an estimated 165,000 gallons of crude oil leaked from its pipeline in Edwardsville, some of which flowed into a creek, according to the state agency.
The cause of the leak was not immediately clear. Marathon wrote in a statement Saturday that an investigation will be conducted.
The company stated that it shut down the pipeline when it detected the leak Friday morning and that cleanup efforts have been underway since. It added that no injuries have been reported, air monitoring has detected no hazardous level of emissions and no water intakes or private wells are located “in the immediate vicinity” of the leak.
“Additional personnel and equipment are en route to the location to assist in cleanup activities,” Marathon stated. “We are working with local, state and federal agencies as we respond.
“MPL’s top priorities are to ensure the safety of responders, the community and to limit environmental impact as we respond to the release and conduct cleanup activities.”
The city of Edwardsville announced at 11:45 a.m. Friday that its fire department and teams from the Madison County Emergency Management Agency, Madison County Hazmat, Phillips 66 Wood River Refinery and Marathon were all responding to the site of the oil leak. The National Transportation Safety Board, a federal agency that investigates “hazardous pipeline events” and other issues, also said it sent a team of investigators to Edwardsville.
Residents reported a strong smell of gas, and the city said in an update Friday afternoon that the odor was a result of the leak.
By 5:30 p.m. Friday, the Illinois Environmental Protection Agency provided the initial estimate that 3,000 barrels, or 165,000 gallons, of oil were released from the pipeline.
The state EPA asked the Attorney General’s office to ensure that Marathon removes all oil in any affected waterway, assesses the pipeline and repairs it as necessary, investigates the extent of the spill to both soil and groundwater and submits and implements a corrective action plan as necessary.
