TREMONT CITY BARREL FILL SITEEPA ID# OHD980612188
Last Updated: August, 2015
The Tremont City Barrel Fill Site is located about 1.5 miles west of Tremont City, Ohio and about 3.5 miles northwest of Springfield, Ohio. The Barrel Fill Site includes 8.5 acres and is located on the northwest end of the larger 80-acre Tremont City property, which also includes a landfill and waste transfer facility. The Site includes the Barrel Fill and any nearby area or media, such as groundwater, contaminated from the Barrel Fill. The approximate 58-acre Tremont City landfill is immediately south of the Barrel Fill and waste transfer facility. The waste transfer facility is a 14-acre parcel immediately east of the Barrel Fill.
In 1976, Ohio EPA permitted the disposal of containerized and uncontainerized liquid waste in the Barrel Fill. From 1976 to 1979, about 51,500 drums and about 300,000 gallons of industrial waste were disposed of in the waste cells. Land application and shallow injection of liquid biodegradable wastes from the food industry occurred on a portion of the Barrel Fill between 1979 and 1980. In 1980, a soil cover was placed over the Barrel Fill and augmented in subsequent years, resulting in a soil cover thickness of 10 to 17 feet over the waste cells.
In approximately 1997, U.S. EPA took over responsibilities from Ohio EPA as the lead regulatory Agency for the former Tremont City Barrel Fill Site.
The site is being addressed through federal and potentially responsible parties' actions.
Threats and Contaminants
In 2002, a U.S. EPA contractor completed a Site Investigation of the former Tremont City Barrel Fill, landfill and waste transfer facility properties. The Site Investigation Summary showed that inorganic and organic contaminant releases from wastes at the Site are continuing to impact media, including groundwater and soil. A number of detected concentrations exceeded background for soil and U.S. EPA maximum contaminant levels for groundwater. The potentially responsible parties (PRPs) at the site then performed a Remedial Investigation (RI) and Feasibility Study (FS). Based on data from the RI, the EPA concluded that a remedial action was necessary to prevent future contamination to the local drinking water aquifer (deep sand and gravel aquifer). Site contaminants of concern include volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and metals.
In October 2002, U.S. EPA negotiated an Administrative Order by Consent (a legal agreement) with PRPs for the PRPs to perform an RI/FS at the Tremont City Barrel Fill Site and to reimburse U.S. EPA for its oversight costs.
In November 2006, U.S. EPA approved the PRPs' RI Report for the Tremont City Barrel Fill Site. The RI showed that the underground waste and drums include a wide variety of contaminants. There are volatile and semi-volatile organic chemicals (VOC and SVOC) and metals levels above screening values in the groundwater. Sediment sampling results exceed ecological screening criteria.
The 2006 RI Report for the Tremont City Barrel Fill Site showed that there is a reasonably anticipated, unacceptable risk to site maintenance workers and trespassers from potential exposure to future groundwater or surface water discharge.
In November 2008, U.S. EPA, in consultation with Ohio EPA, issued an approval with modifications letter in 2008 for the PRPs' July 2008 FS for the Tremont City Barrel Fill Site. In January 2009, the PRPs issued an FS Addendum that included variations of the excavation alternatives and an additional containment alternative involving vertical extraction wells. U.S. EPA provided the PRPs a response to that Addendum.
The PRPs issued a revised FS Addendum in April 2009 that U.S. EPA approved with modifications in February 2010. U.S. EPA issued the Proposed Plan in June 2010 that identified U.S. EPA's preferred alternative to clean up the Site. This preferred alternative involved excavation of all hazardous waste, off-site disposal and treatment of liquid and hazardous waste, and placement of non-hazardous, solid waste in an engineered waste cell on-site.
U.S. EPA presented the Proposed Plan, identifying the Preferred Remedial Alternative, to the public in Springfield, Ohio in June 2010. The public comment period closed August 11, 2010. U.S. EPA reviewed comments received on the Proposed Preferred Remedial Alternative. Comments submitted included a newly proposed cleanup alternative from a PRP. U.S. EPA determined that a Remedial Alternative significantly different from the June 2010 Preferred Remedial Alternative is the best choice to clean up the site, and issued a revised Proposed Plan in May 2011 and re-opened the public comment period. The re-opened public comment period ran from May 31 to July 30, 2011. U.S. EPA presented the new Proposed Plan to the public in Springfield, Ohio on June 22, 2011. On September 28, 2011, U.S. EPA issued a Record of Decision (ROD) for the site, documenting the selected cleanup action of Alternative 9a.
U.S. EPA met periodically with a Community Advisory Group, the Citizens for Wise Approaches Toward Environmental Resources (CF/WATER), to update the group on Site cleanup progress.
Due to a large increase in public and congressional interest at the site, in February 2014, the Region 5 office engaged the U.S. EPA Conflict and Resolution Center to aquire mediator services for the stakeholders at the site. This resulted in the formation of the Tremont City Barrel Fill Workgroup, which has members from the public (People for Safe Water), local government (Clark County), the PRP group, Ohio EPA, and U.S. EPA. The workgroup has held four formal meetings in Springfield or Columbus to date, to better understand the components of Alternatives 4a and 9a, and to have technical experts discuss the hydrogeological setting for the site which was a major factor in EPA's remedy selection. The U.S. EPA is holding a public meeting on the evening of August 27 to discuss with the larger community the information and agreements that resulted from the workgroup meetings. The U.S. EPA is also going to explain a minor potential change in the remedy, called an Explanation of Significant Differences, that would entail eliminating the slurry wall system and instead adding a second flexible membrane liner. The potentially modified remedy would then have a state of the art hazardous waste double liner system.
There has been Congressional interest from U.S. Senator Sherrod Brown, U.S. Senator Rob Portman, and U.S. House of Representatives Speaker John Boehner (8th District).
