Background for Permit Renewal
Hyde County began operating a new reverse osmosis (RO) drinking water treatment facility, 0.30 MGD
capacity, in January 2011. The facility serves Engelhard and the surrounding Hyde County area. The RO
facility operates on the average 12 hours a day with a maximum, monthly average discharge in the last three
years (2019-2022) of 0.034 MGD. Except for anti-scalant additive no other chemicals are added to the
incoming well water.
An Authorization to Construct (AtoC) approval was issued in November 2010 to install the effluent force
main and a submerged single port diffuser in Far Creek, an Engineer Certificate was received in December
2010 indicating completion of the AtoC. The diffuser design and selected location in Far Creek was based
on a CORMIX model reviewed by the Division in 2008. The CORMIX model yielded an IWC of 1.9%
with the inner mixing boundary less than 33 feet from the diffuser.
During the last permit renewal (2016), Total Iron, Total Fluoride, and Total Chlorides monitoring
requirements were removed because there are no saltwater WQ criteria for those parameters. TDS variation
is traceable through conductivity monitoring so TDS monitoring was also removed. Total Arsenic, Zinc,
and Copper were removed because they did not show reasonable potential to be discharged.
RO reject water is conveyed during RO operation via the effluent force main line to the submerged single
port diffuser in Far Creek, a class SA, HQW water in the Tar -Pamlico river basin. The NC Division of
Marine Fisheries list this discharge location as a PNA. This segment of Far Creek continues to be impaired
based on shellfish harvesting restriction which begun in 2006.
The Tar -Pamlico River Basin is designated as NSW, therefore, TN and TP monitoring will continue
quarterly.
Since this discharge is into a class SA water, NC Shellfish Sanitation will review and provide approval for
this permit.

Evaluation of Compliance
No enforcement actions have been taken against this facility during this permit cycle. A July 2020
inspection by WaRO staff did not note any operation/maintenance issues or compliance concerns.
The facility has passed all WET tests.
Evaluation of Instream Data
Conductivity, salinity, NH3-N, DO, temperature, and pH were monitored at two designated instream
location (upstream/downstream) adjacent to the submerged diffuser CORMIX defined mixing zone.
Because this is a tidal receiving stream the actual background value for each parameter could be either the
upstream or downstream value.

DocuSign Envelope ID: E3829147-A9A9-4439-8CEF-F7DCE17A6797
Effluent impacts to instream conductivity, temperature, salinity, and pH impacts were not significant. The
instream DO indicate seasonal variation and with some influence from the consistent low effluent DO
indicated. There were no instances of the receiving stream DO being below the minimum saltwater water
quality standard of 5 mg/L.
Reasonable Potential (RP) Analysis
No Reasonable Potential Analysis was needed for this permit renewal. This permit does not require
monitoring for any parameters that require RPA.
Summary of Permit Changes
The following will be incorporated into this permit:
• Added HUC and Stream Index Number to the supplement to cover page
• Updated eDMR language
• Minor formatting and structure edits
