In accordance with your July 13, 1990 memo please implement
the needed modifications to the leachate collection systems to
determine leachate generation and recharge rate. A water well
indicator and accessory equipment should be purchased and installed
in the leachate collection systems. A leachate storage
container(s) (suggest 55 gallon 17-H metal drums with lids) should
also be purchased for operation and maintenance of the system.
Solid Waste funds should be used for the equipment and supplies.
I will attempt to get funding from DOA for further
modifications, operations and maintenance.

MAINTENANCE AND OPERATIONS AT THE PCB LANDFILL
William L. Meyer
Director
Several modifications in the leachate collection and disposal
system are necessary in order to determine the amount of leachate
being generated, the recharge rate, and the levels of PCB in the
treated leachate prior to disposal. There is also a need to restrict
access to the leachate lagoon.
A water level indicator and accessory equipment should be
purchased and installed in the leachate collection system in order to
determine the water level in the system and calculate the recharge
rate. A leachate storage container should be purchased and installed
to store the leachate until it can be analyzed in order to decide the
proper method of leachate disposal.
In order to restrict access to the leachate lagoon, a fence
should be installed around this area. Over the past few months there
has been evidence that "three-wheelers" (or some other type of small
all-terrain-vehicles) have been operating in the lagoon. In order to
protect the public safety and minimize any liability to the State of
North Carolina, it is very important that a fence be constructed to
inhibit access to this area.
Fencing-in the area of the leachate lagoon would also facilitate
the problem of where to place a storage container for the leachate.
If the leachate lagoon were to be fenced in, the leachate storage
container could be placed in the bottom of the lagoon. This would
restrict public access to the leachate storage tank while the
leachate was being held for analysis prior to disposal. The leachate
lagoon would serve as a built-in secondary containment system in the
event of a leak in the storage tank. Due to the design of the
present leachate collection and treatment system, this seems to me to
be the safest, easiest and most cost effective way to modify the
existing system to enable the leachate to be held prior to disposal.

SUBJECT: Warren County PCB Landfill Operation and Maintenance
The following operation and maintenance project for the Warren
County PCB Landfill is to be implemented as a priority for the Solid
Waste Management Section
1. A field supervisor (Terry Dover or Julian Foscue) is to be
designated project officer.
2. Sufficient staff resources are to be available to implement
the project.
3. A personnel safety plan is be developed for each project
function.
4. Sampling plan is to include:
(a) 4 compost grass samples -representative of landfill
surface ,
(b) 4 compost soil samples -representative of landfill
surface
(c) Sand filter prior to treatment of leachate
(d) Carbon filter prior to treatment of leachate
(e) Leachate samples (4) untreated
Leachate samples (4} from sand filter*
Leachate samples (4) from carbon filter*
(f) Water and sediment in detention pond
5. Analysis to includ.e PCB' s and scan for potential
decomposition products.
6. Sand filter to be purged of soil fines prior to treatment
of leachate (water wash).
7 . C~rbon filter to be purged of soil fines prior to treatment
of leachate (water wash).
8. Irrigation system to be tested with uncontaminated water
prior to utilizing irrigation system use. (CCPS has water
tank that can be utiliz.ed for filter washing and irrigation
system testing.
9. All irrigation equipment should be evaluated for proper
operation with uncontaminated water prior to system
utilization.
10. If the system is properly functioning· ( after testing an
analysis) leachate extraction and treatment should start as
soon as possible.
11. Operational conditions (see Permit #7643R3)
(a) irrigation water after treatment< 1.0 PPB
(b) hydraulic loading~ 0.25 in/week (4400 APD or 30,791
GPW) -
(c) Field Log
(1) Date of irrigation
(2) Vol. of waste water irrigated
(3) Area irrigated
(4) Weather conditions
(5) Analysis of treated waste water
12. Subsidence measurement should be taken (=0.1 in) prior to
pumping and after pumping -may need bench marks -stations
to be established.
13. Other issues
-Identify as soon as possible potential problems (analysis,
resources, equipment, etc.)
-Identify person in Permit Condition #9 as "certified waste
water treatment plant operator" does not mean on-site at
all times but is responsible for operational conditions and
results -DOT supplied the previous WWTP operator.
