Dear Mr "tewart:

SEQUOYAH NUCLEAR PLANT (SQN) - POLYCHLORINATED BIPHENYLS (PCB) IN THE LOW VOLUME WASTE TREATHENT POND This is to confirm the conversations held in your office on November 17 regarding the actions to be taken by the Tennessee Valley Authority relative to the detection of PCB's in the Low Volume Wkste Treatment Pond (LVWTP) at Sequoyah Nuclear Plant. Other participante in thir meeting were Mrs. Ann McGreggor of your staff Wendell L. Williams from SQN and Atraham H. Loudermilk, Jr., of my staff.

The purpose of the meeting was to provide you with data about the PCB's found in the LVWTP at SQN and to reach agreement on an appropriate course of action. It was agreed that, although the PCB concentration is extremely low, an effort needs to be made b/ TVA to reduce that concentration even further. A discussion of the potential usefulness of Calgon carbon filters to reduce the PCB concentration concluded that, at this point, the filters may not provide the best option. Your suggestion to treat the pond con-tents wit'n chemicals to facilitste colloidal sedimentation offer: promise.

We will investigate the feasibility of this approach immediately.

It was pointed out that the idling of the LVWTP indirectly results in the reduced ability of the condensate domineralizer to keep up with the water treatment demands of plant start-up. To avoid this problen, we agreed that the following course of action can be taken while the LvwTP is out of service:

1. DSN 105 can optionally be routed through the cooling tower blowdown line as allowed by the permit.

2. DSN 105 will be monitored for pH after mixing with the wooling tower blowdown at a frequency of twice per week (similiar to the monitoring required for DSN 104). . _

At the completion of efforts te reduce the LVWTP PCB concentratloa we will advise you of our results and seek approval to discharge the rond contents.
