Re NPDES Permit NCO088340 Renewal Application
Dear Mr Thedford-
Please find enclosed one signed original and two copies of the completed application for renewal of the
Millpond WTP NPDES permit Our current permit expires NCO088340 expires May 31, 2018.
Please note that all discharge under the current permit is generated from this water treatment plant.
The backwash water produced comes from 2 sand filters and 2 ionic water softeners.
There have been no changes in treatment since the issuance of the current permit.
Since the backwash water does not produce any solids or sludge, Pamlico County Water System does
not have a sludge management plan or a solids handling plan.
Thank you for your assistance in this matter If any further information is needed, please feel free to
contact the Operator in Responsible Charge, Mr. Jeff Sanders or Al Gerard, Field Operations Manager at
252-745-5453.
Sincerely,
