Subject: Compliance Evaluation Inspection
PCB Contaminated Soil Landfill
Landfill Leachate Spray Irrigation Facilities
Warren County
Dear Secretary Lofton:
It has come to my attention that the Department of
Administration will be assuming responsibility from the
Department of Crime Control and Public Safety for the PCB
Contaminated Soil Landfill Leachate Spray Irrigation permit which
is being considered for renewal by the Division. In that regard,
personnel from this office conducted a site inspection of the
subject facilities on May 15, 1990. The purpose of this letter
is to apprise you of the results of that inspection.
The facilities appeared to be reasonably well maintained,
although the grass on the spray irrigation area needed cutting,
and the individual components of the spray irrigation facilities
seemed capable of operation. According to the records that were
submitted to us by the Solid Waste Management Section, there has
been very little leachate detected in the landfill 1 s leachate
collection system in recent years. Since the landfill is capped
with a clay cap, it may be reasonable to assume that very little
rainfall infiltrates the cap and that most of what falls onto the
landfill site runs off. The other possibility is that the
collection system is not functioning properly. Since there has
not been any significant amount of leachate pumped out of the
collection system, there has not been much water pwnped into the
holding pond. As I understand it the pond has a clay liner which
should be relatively impermeable. At the time of the inspection ~
the pond was dry. With all of the rain that we have had 1
recently, I would have suspected that some water would have been/,, \
in the pond. I question whether the pond would function ·
satisfactorily if needed.

The results of various sampling and analysis that have
occurred over the years were submitted to my office by the Solid
Waste Management Section. These results do not indicate that
PCB 1 s are getting into the groundwaters or migrating off of the
site; therefore, it will be my recommendation to the Director of
Environmental Management that the subject permit be reissued to
the Department of Administration once all required information
has been received and reviewed by this Division.
If you have any questions on these matters, feel free to
contact me or Randy Jones at [phone].
