RE: NPDES Permit Renewal NC0040061 (Beaverdam Creek WTP)
Wren Thedford:
This letter is to request a renewal of NPDES permit number NC0040061. This permit was
originally issued on December 6, 1983. Since the issuance of the last permit, we have construct
2 new solids settling lagoons as well as an upgraded supernatant pumping station. All
supernatant is either recycled to the head of the plant or discharged to the sanitary sewer. The
outfall for the lime settling part of the plant operation has been removed (old outfall 001). Old
Outfalls 002 and 003 are the drains on the potable water storage tanks. They still exist and have
been renamed Outfall 001 and 002 for this permit period. These tanks do not contain chemical
disinfection and are pH adjusted to 7.2. Discharge from the outfalls is very rare. There has been
no discharge from any of the Outfalls in over 10 years.
Sincerely
Jeremy S. Sexton
Water Resources Superintendent
