The Brandt Pike Terminal Site includes four active petroleum products distribution facilities at the Brandt Pike Oil Terminal located at 621 Brandt Pike, Dayton, OH. Each of the four Facilities receives its petroleum products via the Inland Pipeline then pipes the petroleum products to large above-ground storage tanks and dispenses petroleum products to tank trucks or other pipelines for further distribution. The Facilities have been operating since the 1930's-1940's. The storage capacity of each of the facilities is between 8 million to 12 million gallons of oil. The Site is located in a mixed residential, commercial and industrial area. An inspection of the facilities revealed:
1) Beneath the Facilities is a sole source aquifer that provides water for the City of Dayton. Areas of the Site are within Dayton's wellfield protection area and are considered to be within a one-year travel time to the wellfield. Approximately one-half mile north and downgradient of the Facilities is the City of Dayton's drinking water wellfield and the Miami River. The Miami Wellfield provides water to approximately 440,000 persons in the Dayton area.
2) In 1986, Ohio EPA (OEPA), Emergency Response, responded to a report of an oil spill at the Site. Monitoring wells were installed under the direction of OEPA. The monitoring wells indicated that there was widespread petroleum-related groundwater contamination by benzene, toluene, ethylbenzene and xylene (BTEX) beneath the Brandt Pike oil distribution facilities and pipeline. Free phase diesel fuel, jet fuel and gasoline were found floating on the water table in such quantities to indicate that significant releases of oil products have occurred to the groundwater at the Site.
3) In April 1998, sampling at the Site detected a four inch layer of light non-aqueous phase liquid (LNAPL) in a soil vapor recovery well, in close proximity to the Inland Pipeline. Groundwater sampling conducted in 1998 at a Site well revealed a BTEX concentration of 63,300 ppb in a monitoring well. Methyl Tertiary-Butyl Ether (MTBE) was detected in the soil and groundwater at the Site in 1998.
4) The City of Dayton installed two monitoring wells immediately north of the Site as part of their wellfield protection plan on January 31, 2006. Sampling of these monitoring wells has detected levels of MTBE in excess of 85 ppb and benzene in excess of 164 ppb, indicating groundwater containing oil, MTBE and benzene is moving downgradient in the direction of the residential neighborhood to the north of the Site and in the direction of the Miami River and the Miami Wellfield. On April 30, 2007, Dayton reported that MTBE was detected for the first time in a groundwater monitoring well at a level of 0.280 ppb.
5) Historic spills at the Site have contributed to the presence of a plume of commingled oil, benzene and MTBE contamination in groundwater at and downgradient of the Site which may present an imminent and substantial endangerment to health or the environment because the groundwater contamination plume appears to be moving downgradient in the general direction of (1) a residential area where some residents may continue to use private wells, (2) the Miami River and (3) the City of Dayton's Miami Wellfield which pumps groundwater from the sole source aquifer.
In July 2007, the U.S. EPA and the following respondents have entered into an Administrative Order by Consent (AOC):
BP Products North America Inc
BP Oil Company
Buckeye Terminals, LLC
Inland Corporation
CITGO Petroleum Corporation
Sunoco, Inc (R&N)
Pursuant to the AOC and working under an EPA approved work plan, the Respondents, in order to determine the extent of contamination, will complete the following activities:
A) Perform a field investigation to determine the extent of oil, MTBE and benzene in the groundwater including the installation of monitoring wells screened to detect oil, MTBE and benzene and establish a groundwater gradient.
B) Analyze the fate and transport of oil, MTBE and benzene in groundwater in the area of the Site with respect to the following potential downgradient receptors: (1) any residences with private wells, (2) the Miami River, and (3) the Dayton Miami Wellfield.
C) Evaluate the ongoing petroleum recovery systems to determine their impact on the transport of the oil, MTBE and benzene in groundwater.
D) Perform a vapor intrusion study in the downgradient offsite areas.
September 24, 2007 Update: The Administrative Order by Consent (AOC) has been added to the documents section.
October 18, 2007 Update: The AOC 30 day public comment period started on October 18, 2007. The AOC and related information can be accessed and reviewed via the EPA Website:

December 3, 2007 Update: The effective date of the AOC is December 3, 2007.
On January 10, 2008, U.S. EPA received a monthly report (month ending December 31, 2007) from the PRPs.
January 11, 2008 Update: The December 2007 Monthly Report has been added to the documents section of this website. Pursuant to the AOC, the Work Plan will be submitted to EPA in January 2008 for EPA review.
On January 17, 2008, the DRAFT "Investigation and Fate and Transport Evaluation Work Plan" was submitted to U.S. EPA, Ohio EPA and the City of Dayton for review.
January 22, 2008 Update: According to BP personnel, on Sunday morning, January 20, approximately 9,500 gallons of Jet-A fuel from Tank #6 was released. The cause of the release has yet to be determined, but preliminary observations from BP personnel indicate an equipment or process malfunction. No free product was observed or recovered within the earthen dike area. The entire spill saturated the ground within the tank farm and subsequently migrated onto the groundwater table, which is approximately 20 feet below ground surface. BP contractors on site to determine if excavating test pits/trenches can recover any free product. In addition, four 4-inch temporary recovery wells will be installed to aid in the recovery of the free product. More details to follow in a POLREP.
