A portable su:p pump was utilized to pu=p the ficodvater directly to the plant's cain discharge (001), bypassing the oily vaste treatment s3 stem. Estimated total discharge flow was less than 7000 gallons.
4.
Apparent Cause:
During the plant's return to power, the main boiler feed pumps were placed in operation. Leakage from these pumps (esticated at 100 sp= of demineral-ised water) resulted in the flooding cf the turbine building su=p in excess of the su=p pump's capacity.

If not immediately corrected, the anticipated time the condition is expected to continue:

6.
Corrective Action - The following corrective action was taken or vill be I
taken to reduce, eliminate and prevent recurrence:
The feed pump leakage was reduced to where the turbine building sump pump could handle the inflow. Two samples of the undiluted floodwater were collected for oil and grease analysis. The analytical results will be included in the MOR for November 1984. The samples appeared visually clear of any oil'or grease.

Nature of the loss 1
The demineralizer regenerants lost from 2300 hrs on 5/1 to 0148 hours0.00171 days <br />0.0411 hours <br />2.44709e-4 weeks <br />5.6314e-5 months <br /> on 5/2 included 200 gallons during the 40 minutes from discovery until the pH was analyzed at 2.33 and 640 gallons from then until the leak ceased at 0148 hours0.00171 days <br />0.0411 hours <br />2.44709e-4 weeks <br />5.6314e-5 months <br /> on 5/2. The 840 gallons were contained in the sand-immediately under the east half of the tank (T921). As a precautionary measure, one bag of slaked line was spread in the area to insure neu-tralization of the acid. These regenerants contained an equivalent of 11.8 lbs of unneutralized sulfuric acid lost to the soil (200 gal x 3.785 1/ gal x 0.013 eq/1 x 49g H SO /eq x lb/454g) + (640 gal x 3.785 2 g 1/ gal x 0.0046 eq/1 x 49g H SO /eq x lb/454g) = 11.816 y 4 None of the listed regenerants reached Lake Michigan as an uncontrolled I
spill'(although the major portion of the tank contents was released to the Lake through outfalls 00F/001 as a normal release in conformance with the requirements of NPDES Permit MI0001457 and Plant procedures).
There were no personal injuries associated with this loss and no proper-ty damage.
The caustic loss included 225 gal of 20% caustic from the time of discovery until contents were diluted with water (45 min x 5 gal / min) plus 900 gallons of 0.1 normal caustic solution from time of dilution until pH dropped to 12.2 plus 250 gallons 0.01 normal caustic solution until pH reached 1.7 at 1750 hours0.0203 days <br />0.486 hours <br />0.00289 weeks <br />6.65875e-4 months <br />. An additional amount of 500 gallons-was lost during draining of the tank for a total volume lost of 1875 gallons. About 50% of the lost caustic was pumped back into the MIO585-0018A-ENO3
participating in an effort to effect changes to the physical tank and the systems, and maintaining the system to prevent or minimize future spill. events. Until all aspects of the operation are scrutinized, it is impossible to predict what changes will be made; however, results from this effort should be available later this year.
VI.
Cleanup An evaluation is being performed at the present time to ascertain the type and extent of cleanup required following a loss of this nature.
Any cleanup action should be started the week of May 6, 1985 unless unforeseen factors delay the cleanup.

Plainvell, MI 49050 TFESPOF. MEA MINEFX. OI' 1.EAK AT TEE PAhISADES FLANT As we discussed over the telephene en January 9, 1955, the folleving infer:a-tien is provided relative to the transfer =er cil leak at the Ce pany's Pali-sades Nuclear Plant which was verbally reperted to yeu en February 24, 195t.
At that tire, Mr F.cger Ehiting cf cur staff provided yeu a preli=itary de-scriptie cf the leak but no written account of the i=eident er of the Ce:pa-ny's follev-up action was provided.
The incident involved the Plant's Static: Power Transfor:er No 1-1 which vas knevn threugh testing to centaf: PC3-conta:1:ated (53 pp=) =ineral oil dielectric fluid. The leak was first detected in late Neve:Ser, 1953 by a
=aintenance engineer; he subsequently (February 21,195t) centacted the Plant's senior chemist who appraised hi= of the unit's lev-level PC3 centa=1-natics and brcught the leak to the attentien of the Ce:pany's Envirennental Depart =ent.
The leak criginated fre= a defective bushing near the tcp cf the transfer =er which allowed a s=411 quantity (<1 pint / day) of =ineral cil to seep dev: and drip into the catch basin /su=; syste: beneath the unit. There was concern that although the leaked = iteral cil had been initially centained in the catch ent syster, sete of the oil =ight have been inadvertently dis-charged to the surrounding soil and to a stor= drain during "as =eeded" purping of the su=p.
To ec= fir = pessible centa:ination, sa:ples for PC3 analysis were taken fre: (1) the soil / rocks that were part of the catch basic around and under the transfer =er, (2) fre= soil near the su=p and ster: drain, (3) fre: absorbent pads placed in the se=p, and (4) fre= subsurface water in the surp. In additien, (5) mineral oil fre= the transfer =er was retested to confir: its PC3 cencentratien. PCB concentratices feund in the five catego-ries cf sa:ples (in the order stated above) were: (1) 0.2 - 16.8 pp=; (2) <0.1
- 1.3 pp=; (3) 12.9 - 61.4 pp=; (4) <1 pp:; and (5) 65.7 pp=.
Based en analysis cf these results, it was concluded that the PC3 ce=ta:inatien of concern was restricted to the soil / rocks around and under the transfer:er and to the abserheet pads in the su=p.
Cleanup activities were therefore fecused on these areas.
OC0185-0040A-ENO3
2 Following repair of the transformer and retrofilling with non-PCB oil in early April 1984, cleanup and repair of the transformer catch basin ard sump was 1
performed. This operation resulted in the removal and replacement of approxi-i
~
aately 30 cubic yards of soil / rocks from the area near the transformer and the disposal of the absorbent pads which had been periodically replaced in the sump while avaiting repair of the transformer. The operation was concluded by t
testing a final water sample from the sump (it tested <1 ppm PCB) and pumping the sump water into the storm drain.
As discussed with you, because there was no loss of PCBs to the environment (it was retained in the transformer catch basin / sump system and ultimately properly disposed), no formal report of this loss will be made to the DNR.
