Current Site StatusOn September 11, 1997 EPA issued a Unilateral Administrative Order For Removal Activities (“Order”) to the Respondents. The Order required the Respondents to prevent oil from entering the Kishacoquillas Creek adjacent to the Site, and to develop an extent of contamination study to determine the extent and depth of all oil contamination at the Site. At this time the Respondents are operating an oil/water separator to capture any oil in the ground water from wells located on the Site. An extent of contamination study has been done by the Respondents utilizing their wells and the Pennsylvania Department of Transportation (“PennDOT”) wells. EPA closed the Order with the Respondents in September 2002.
Site DescriptionThe Route 522 Bridge Site (“Site”) is located at 401 East Walnut Street is Lewistown, Mifflin County, Pennsylvania. The Site consists of approximately two acres and is bordered to the north by a wooded area, to the south by Route 522, to the east by private residences and to the west by the Kishacoquillas Creek. An unnamed tributary runs southwest through the Site and into the Kishacoquillas Creek, and the Creek flows into the Juniata River. The Site is an above ground storage tank farm that stores almost 1 million gallons of home heating and motor oil, gasoline, kerosene and diesel fuel. The Site also contains five underground storage tanks, a gasoline station and a convenience store.
Site ResponsibilityThis site is being addressed by a Potentially Responsible Party under an EPA Superfund Removal Order.
NPL Listing HistoryThis Site is not on the National Priorities List.
Threats and ContaminantsOil, including petroleum and its constituents, can pose a threat to human health and the environment. Benzene, toluene, ethylbenzene, and xylene (“BTEX”) and some polynuclear aromatic hydrocarbon (“PAH”) compounds have been linked to adverse developmental effects in laboratory animals. Inhalation exposure to benzene has been associated with impaired reproduction in women. Skin contact with benzene and ethylbenzene causes dermatitis. Inhalation of high concentrations of benzene, xylene, and toluene in air causes central nervous system depression. Benzene is a known human carcinogen. The PAH components of petroleum are associated with a variety of toxic effects, including dermatitis; several PAHs are probable human carcinogens.
In June 1991 PennDOT initiated a bridge abutment construction project replace the Route 522 bridge over the Kishacoquillas Creek. During the construction, PennDOT discovered oil in excavation areas around the old bridge abutments. PennDOT redesigned the new bridge abutment to act also as a retaining wall to deter oil from seeping into the Kishacoquillas Creek. PennDOT also constructed several ground-water monitoring wells in proximity to the existing underground storage tanks. Analysis of samples taken from the wells in August 1991 and November 1992 indicated elevated levels of Total Petroleum Hydrocarbons (“TPH”) and BTEX. One of PennDOT's monitoring wells located approximately 100 feet from the Kishacoquillas Creek was inspected in May 1992 revealed a significant amount of gasoline in the well.
In June 1992, the Pennsylvania Department of Environmental Protection (“PADEP”) sent a Notice of Violation to the Respondents instructing them to dispose of the petroleum product in the ground water wells to mitigate the release or/threat of release of oil into the Kishacoquillas Creek.
In November 1996 PennDOT requested EPA's assistance at the Site, and in response to that request EPA performed a multi-media Site Assessment inspection of the Site in December 1996, as well as a Spill Prevention Control and Countermeasures ("SPCC") inspection. At the time of the inspection, the EPA On-Scene Coordinator ("OSC") observed significant amounts of gasoline in one of the monitoring wells on the Site, and observed a liquid discharging from the bank adjacent to the Facility and into the Kishacoquillas Creek that created an oil sheen on the surface of the water. This sheen exhibited the cohesive characteristics and odor of a petroleum product.
In April 1997, EPA sent a "Notice to Suspected Discharger” letter to the Respondents and in April 1997, determined that there was an imminent and substantial threat to the public health and welfare at the Site.
