Agreement with Murphy, Pioneer and Samson requires continued groundwater monitoring and contingencies for treatment or alternate supply

(Denver, Colorado—March 26, 2012) The U.S. Environmental Protection Agency has reached an agreement with three oil production companies operating on the Fort Peck Reservation in Montana requiring the companies to address groundwater contamination threatening the City of Poplar’s public water supply system.

The agreement with Murphy Exploration & Production Co. (Murphy), Pioneer Natural Resources USA, Inc. (Pioneer), and SGH Enterprises, Inc. (Samson) requires the companies to continue to monitor the City of Poplar’s public water supply monthly and provide treatment or an alternate drinking water source if water quality degrades to a point that presents a public health risk. These requirements will remain in effect until a new and safe source of drinking water is secured by the City of Poplar. The agreement also requires the companies to pay $320,000 to the City to reimburse costs related to water infrastructure and relocating water wells.

The administrative order, issued under the Safe Drinking Water Act, replaces an emergency order issued by EPA in December 2010. The companies had previously appealed this order in federal court, which referred the case to a mediation process. The agreement announced today is a result of that process.

“Murphy, Pioneer and Samson have made a commitment to ensure that the City of Poplar’s taps remain safe,” said Jim Martin, EPA’s regional administrator in Denver. “The companies will continue to monitor water quality and will take all actions necessary to maintain an uninterrupted supply of safe water to residents.”

Over the past several years, groundwater sampling results indicate that contamination related to production in the East Poplar oilfield has reached the City of Poplar’s water supply.

The source of this contamination is produced brine, highly saline wastewater containing trace metals, inorganic salt concentrations, and volatile organic compounds. EPA estimates that more than 40 million gallons of brine entered the drinking water aquifer over the span of five decades. The direction of the brine plume movement is generally toward the City of Poplar.

While treated water from the City of Poplar’s water system is currently safe to drink, monthly samples collected by the oil companies indicate an upward trend in total dissolved solids, chloride and sodium. Under the order announced today, EPA and the companies have identified trigger values that will allow time for action before the public water supply presents any health risks. If these values are met, the companies will take immediate steps to secure additional treatment or provide alternative water to ensure contamination levels are below human health thresholds.

A long-term alternative water source for the City of Poplar is currently being developed through construction of a pipeline from the Missouri River. The City also has plans to relocate its water wells to secure a back-up supply. These efforts are expected to be completed as early as this year.

EPA, the State of Montana, the Fort Peck Tribes, the U.S. Geological Survey and other agencies have been aware of groundwater contamination in the East Poplar oil field for several decades. Various studies have been done in the area, and the nature, extent and movement of the plumes are relatively well known. EPA has addressed past contamination through four Safe Drinking Water Act orders issued to production companies between 1999 and 2004. Murphy, Pioneer and Samson are, directly or through corporate acquisition, historic oil producers in the East Poplar oil field.

Poplar is the seat of the Fort Peck Assiniboine and Sioux Tribes. The Poplar-area public water system, the Fort Peck Tribe Water Resource, serves approximately 3,000 people, including tribal and non-tribal households.

USEPA Region 7 – Eaton Corporation Settlement on TCE contamination

Settlement to Require Eaton Corporation to Address TCE Contamination at Vehicle Group Plant in Kearney, Neb.

FOR IMMEDIATE RELEASE

(Kansas City, Kan., Jan. 12, 2012) – EPA Region 7 and the Eaton Corporation have reached a settlement through which the company has agreed to conduct certain activities to address trichloroethylene (TCE) contamination in groundwater at its Vehicle Group Plant and surrounding areas in Kearney, Neb.

Eaton Corporation has owned the 57-acre site at 4200 Highway 30 East, in Kearney, since 1969. TCE was used as a degreasing agent in the manufacture of automotive and heavy-duty engine valves and gears at the site.

TCE is a colorless liquid which is most commonly used as a solvent for cleaning metal parts. TCE is a known human carcinogen that has been found in concentrations in groundwater at and near the site that exceed the drinking water standard.

According to an administrative order on consent, placed on public notice today by EPA in Kansas City, Kan., TCE contamination in groundwater at the Eaton Corporation Vehicle Group Plant site in Kearney was first detected in 1986, the result of an apparent leak from underground storage tank lines. Since that time, the company has installed and modified a series of systems to extract TCE from groundwater at the site, and monitoring wells to track its movement underground.

Currently, Eaton Corporation operates two groundwater extraction systems – one on-site, another off-site – in an effort to contain the underground TCE plume. Contamination from the site has in the past impacted private drinking water supplies.

EPA’s administrative order on consent requires Eaton to operate and maintain on-site and off-site groundwater extraction systems to contain and reduce TCE contamination in the groundwater at and coming from the site. Operation of the extraction systems will continue as long as needed to prevent significant contaminant plume migration. The order also would require Eaton Corporation to conduct a review of the remedy’s performance after five years, submit a remedy completion report to EPA, and maintain a series of institutional controls at the site.

The proposed settlement is subject to a 30-day public comment period. EPA will consider all comments received, and may modify or withdraw its consent to the settlement if comments disclose facts or considerations indicating the settlement is inappropriate, improper or inadequate. As provided by the federal Resource Conservation and Recovery Act, commenters may also request a public meeting to be held in the affected area.

Copies of the proposed order will be available for public inspection at the Kearney Public Library, 2020 1st Avenue, Kearney, Neb., 68847, and at the EPA Region 7 Records Center, 901 North 5th Street, Kansas City, Kan., 66101. A copy of the proposed settlement may also be obtained from the Regional Docket Clerk, EPA Region 7, 901 North 5th Street, Kansas City, Kan., 66101. Persons submitting comments should reference EPA Docket Number RCRA-07-2011-0024.
