$150m "Unexpected Funds"
AVA
DEHNR
If the "state" does not make some attempt to obtain funds for detoxification
it will not go unnoticed by Warren county.
If the state does not obtain funding we will not be able to comply with the
existing conditions of the landfill permit with respect to managing the water
contained in the landfill.
Anticipated budget needs :
Capital Improvement
Reconstruct surface liner systems
Construct liner in leachate holding pond
Design, install leachate removal system
Continuation Budget
WWTP operator contract - 1 position
Monitoring/analytical annual, maintenance

CAPITAL IMPROVEMENTS FOR PCB LANDFILL, WARREN COUNTY
I. RECONSTRUCT SURFACE LINER:
This part of the project would involve removing the existing agricultural layer of soil,
screening and stockpiling on site, then smoothing the existing clay liner. A new cap would be
installed over the old one using a Geo-synthetic Clay (permeability of 5 x IO e-9 cm/sec),
followed by a VLDPE or equivalent synthetic liner ( 40 mil thick), and a double bonded geonet
layer installed for drainage. At least 24-36 inches of protective cover will be placed over the
landfill and grass established. Edge drains may be installed to collect runoff from the geonets,
and subsequently directed to the sedimentation basin. Three gas vents will be added to the
existing one.
II. LINING OF THE SEDIMENTATION BASIN
The current sedimentation basin would be cleaned and graded, a Geo-synthetic clay liner
and 40 mil VLDPE liner would be installed. A "Fabriform" protective cover would be placed
over the plastic liner. The basin would be used to collect water from the landfill and
subsequently pumped back over the landfill surface through an irrigation system.
III. LEACHATE REMOVAL SYSTEM
A leachate removal system will be designed and installed in the two bore-holes
established this spring in the landfill and on the existing leachate pumping system. Leachate
would be systematically and continuously removed from the landfill, passed through the sand
and carbon filter beds and discharged to the sedimentation basin and eventually spray irrigated
over the landfill.
IV. WASTEWATER PLANT OPERA TOR
A certified Waste Water Treatment Plant Operator must be employed by the state to
oversee the actual process of removing and treating the water from the landfill. There is a
potential to have this position as a "part-time" position once the system is in place and operating
via an automatic system.
V. EPACOMPLIANCE
It is anticipated that EPA will issue a compliance order to the state within the next 60
days, upon their completion of a review of lab data from the recent sampling event. This order
will most assuredly include removal of water from the landfill and potentially a requrirement for
a new cap, depending on the funding available (or decision by the state) for detoxification. No
other funds are available to complete this project.
