PCS PHOSPHATE - TANK FARM REMEDIAL ACTION PLAN
QUARTERLY OPERATIONAL AND MAINTENANCE REPORT FOR
THE INJECTION AND WITHDRAWAL WATER WELLS
FEBRUARY - APRIL 1997
The Tank Farm Remediation System consists of a series of seven
injection water wells located on the south side of the Tank Farm
Area and a series of fourteen (14) water withdrawal wells
located on the north side of the Tank Farm Area.
Injection Water Well System
The injection water well system operated with the DPW Water -
Anthracite Sand Filter/Ultraviolet Light (ASF/UV) disinfection
system throughout the period. Only short periods of planned
downtime were experienced for preventative maintenance and inlet
DPW Water strainer cleaning.
Daily operational data are collected by the Shipping Department
and reported to the Operations Environmental Department. The
total volume of water injected this period was:

The Withdrawal Well System operated the entire period. The
withdrawal water well pumps are monitored daily by the area
Maintenance Department and preventative maintenance work is
performed is needed. The total withdrawal water volumes for the
period are:

Some short periods of planned downtime for preventative
maintenance, pipe header cleaning, and troubleshooting on
individual pumps in the fourteen well system were experienced.
On 3/28 all of the pipe headers were cleaned by flushing with
hot water and air. Specific well and pump maintenance
activities include:

Confined Sand Formation Withdrawal Wells (SWW)
SWW-1; On January 27 the pump cycle counter started
malfunctioning only counting cycles part of the time and the
sensor was replaced on February 1. On February 1 the pump was
replaced due to scale build up plugging 90% of bottom strainer.
On 2/17 the pump stopped and had to be shaken to start. On 2/18
the pump stopped and was removed for inspection. It was
determined that the pump and well had scaled up and required
cleaning with HC1. On 2/20 the pump and well were cleaned with
HC1 and placed back in service. On 3/10 the pump stopped and
was determined to need cleaning. On 3/11 the pump and discharge
line were cleaned. On 3/21 the pump was operating slower than
normal and it was determined to need cleaning. On 3/31 the pump
stopped. On 4/1 the pump was removed and cleaned. On 4/1 the
well was cleaned for 26 hours with HC1. On 4/2 the pump and
well were placed back in service. On 4/7 the pump stopped and
had to be shaken to start. On 4/18 the pump stopped. On 4/21
the pump was repaired and the plugged discharge line to the
header was cleaned.

cleaned. On 4/7 the well was cleaned for 6 hours with HC1 and
placed back in service the same day.
SWW-3; On 4/29 the pump stopped, was removed and cleaned, and
placed back in service.
SWW-4; On 2/3 -a loose wire was repaired on the cycle counter.
On 3/24 the cycle counter malfunctioned. On 3/26 the counter
sensor was cleaned and it began operating properly. On 4/10 the

cam assembly was replaced due to a broken snap ring on the air
valve and the pump was placed back in service.
SWW-5; On 2/4 the air line to the pump broke off and was
repaired.
SWW-6; No problems.
SWW-7; No problems.
Croatan Formation Withdrawal Wells (CWW)
CWW-1; The counter sensor was replaced on February 1. On 2/21
the pump stopped and had to be shaken to start. On 3/31 the
pump stopped and had to be shaken to start.
CWW-2; On 2/3 the cycle counter was working only part of the
time. On 2/4 the pump stopped, was removed, cleaned and placed
back in service. On 2/11-12 the cycle counter was working only
3

part of the time. On 2/13 the pump was removed, cleaned, and
placed back in service with a new cycle counter sensor. On 2/25
