U.S. EPA Explains Changes
In Proposed Cleanup Plan
Tremont City Barrel Fill Site
German Township, Ohio August 2015
The U.S. Environmental Protection Agency, after consultation with the Ohio
Environmental Protection Agency, has determined changes should be made to
the selected cleanup plan for the Tremont Barrel Fill site. The federal Agency
believes the changes are significant but do not fundamentally alter the overall
cleanup for the site. The changes are outlined in an EPA document called
Explanation of Significant Differences, or ESD. The modifications involve
replacing the slurry wall, liner and leakage collection system with an industry-
standard double liner system designed for hazardous waste landfills (see
diagram on back). U.S. EPA has concluded this change will result in an equal or
more stringent level of protection to people and the environment. The proposed
changes are also more cost-effective than the old plan, saving about
$2 million, and are generally considered more acceptable by all parties in the
Tremont Barrel Fill Technical Workgroup. Re-compacted clay will lie beneath
the double-liner system. There will also be a drainage layer and drain pipes in
both flexible membrane liners to remove any remaining liquid that might be in
the contained wastes.
Other components of the cleanup selected by U.S. EPA will not change. These
include:
• Removing the existing clean soil cover and holding it on-site. This will
be reused for the compacted soil cover above the hazardous waste liner.
• Excavating the drums, uncontained waste and contaminated soil from
each of the 50 waste cells. Any waste, including sludge, that is
determined to be liquid will be sent for off-site treatment and disposal.
• Removing non-liquid hazardous waste from the drums and preparing
the drums for reburial.
• Pumping and removing all liquid waste, both in and outside of
containers. The liquid waste will be taken off-site to be treated and
disposed.
• Consolidating uncontained waste and solid hazardous and nonhazardous
waste in drums and contaminated soil in a newly constructed engineered
lined cell with leachate (seepage) collection. The drums and their
contents will be crushed to reduce volume and to help remove any
liquids from the drums.
• Installing a hazardous waste landfill cover over the waste left on-site.
• Long-term underground water (groundwater) monitoring.
• Preventing or limiting certain future land uses and the use of site
groundwater.
• Placing fencing and signs around the site.
• Contingency planning in case officials must take action if unexpected
conditions occur.
