Re: Warren County PCB Landfill
Dear Mr. Phillips:
Since at least April of 1984 the irrigation system at the Warren County PCB
Landfill has been inoperable because of broken risers and influent lines.
Apparently the lack of an irrigation system has not adversely affected
vegetative cover of the landfill cap. Nor has any sign of erosion of the
cap been evident. While no adverse affects have been noted, as yet, it is
critical that the irrigation system be operational, as needed, to maintain
the vegetative cover and the structural integrity of the cap. The Depart.rrent
of Criroo Control and Public Safety should ensure that the irrigation system
is operational follCMing the winter freezes. An operational date of April 1,
1985 should be adequate to guard against damage tq the irrigation system due
to freezes.
If you have any questions, please contact ire. woors2--~#\
