COMMENT
Discovery Vacation Club, Inc. (formerly Willow Valley Assoc., Ltd.)
Watauga County
Permit No. NCO061425
Barry Huneycutt, WQ Training and Certification called me concerning the rating sheet attached to the
renewal comments. He wanted to give the facility a chance to stop chlorinating/dechlorinating during low flows.
The reason for this was to allow the facility to keep a Grade H operator instead of moving to a Grade III operator.
Evidently Barry has mailed them a letter addressing this problem. I have yet to receive a copy.
The ORC called me and said the UV unit breaks often due to power surges. The chlorine/dechlor is used
when this happens. The unit also can not work during low flow conditions because the water does not contact the
bulbs sufficiently.
We have no problems with giving the facility a chance to correct these problem. I called the contract
operator, who said it would be necessary to reconstruct the UV trough to make sure it receives enough flow to be
effective. Also, back up bulbs will need to be ordered. Please address this modification of the plant with a
condition in the permit requiring an authorization to construct:
Plans and Specifications and a request for Authorization to Construct for the modification of the LTV system
to allow it to function during low flow conditions must be submitted within 90 days of permit reissuance.
The UV modifications must be installed within 180 days after permit reissuance.
Should you have any questions, please contact me at your earliest convenience.
