Subject: Renewal of NPDES Permit
NCO086584
Belhaven WTP
Beaufort County
Dear Mr. Grant:
Dee Freeman
Secretary
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
This permit renewal has the following differences from your current permit:
➢ The Flow limit has been removed in accordance with our current permitting strategy for membrane
Water Treatment Plants. Continue to monitor and report flow.
➢ The limit for Nickel has been removed. Monitoring has been changed to quarterly as the result of EPA
required statistical analysis of DMR records.
➢ Monthly monitoring and reporting for turbidity has been added back to the permit in accordance with
EPA requirements.
➢ Monitoring for Copper, Fluoride, Iron and Zinc has been changed to Quarterly from Monthly.
➢ pH limits were changed to 6.0 to 9.0 S.U. due to the fresh water classification of the receiving
stream.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt
of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center,
Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.

A. (2.) ACUTE TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent
Concentration" (Revised -July, 1992 or subsequent versions). The monitoring shall be performed as a Mysid
Shrimp (Mysidopsis Bahia) 24 hour static test. The effluent concentration at which there may be at no time
significant acute mortality is 90% (defined as treatment two in the procedure document). Effluent samples for
self -monitoring purposes must be obtained during representative effluent discharge below all waste treatment.
The tests will be performed during the months of January, April, July, and October.
.All toxicity testing results required as part of this permit condition will be entered on the Effluent -Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGE3E.
Additionally, DWQ Form AT-2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed
in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent
toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at
the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to
include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
follow-up testing to be completed no later than the last day of the month following the month of the initial

1.0 Proposed Changes Incorporated into Permit Renewal
In keeping with our Permitting Strategy for membrane WTPs, the flow limit has been removed, but monitoring
is still required. In keeping with EPA requirements, turbidity monitoring without a limit has been added back to
the permit. The receiving stream, Pantego Creek changes classification at the highway 264 bridge. On the
upstream side, the classification is C-NSW, Sw, and is not listed on the 2010 303(d) list. On the downstream
side, it is classified as SC -NSW, and is listed on the 303(d) list as impaired for chlorophyll a and for copper.
The discharge had been considered going to the SC -NSW water, but a review of the map sent with the renewal
application clearly shows the discharge going about 200 feet above the bridge into class C waters. The pH
limits have been changed to reflect this.
2.0 Summary
This is a renewal for an existing reverse osmosis membrane filtration water plant for the Town of Belhaven.
This permit was first issued in 1999 and a number of limits and monitoring requirements were included based
on expected effluent characteristics. For this renewal the permit will be further tailored based on the results of
those tests, as well as to align with the current membrane WTP strategy.

RPA Analysis
RPAs were performed for chlorides, copper, fluoride, iron, nickel and zinc. Chlorides showed no RP. The
maximum predicted Cw was 84 ug/ L, compared to the WQ standard of 230,000 ug/ L. Monitoring for
chlorides will be removed from the permit. The limit for nickel will be removed, as there is no reasonable
potential for the facility's discharge to cause a water quality violation for this parameter. Copper, iron, and
zinc all showed RP, but these are action level parameters; the plant has consistently passed all WET tests,
so no limits are required. Monitoring for copper, fluoride, iron, nickel, and zinc will be changed to
quarterly from monthly.
WET Test Results
The Belhaven WTP has a quarterly acute monitoring requirement using an effluent concentration of 90%
and mysid shrimp. The facility has passed all WET tests during the current permit cycle.
Correspondence File Review/Compliance History
Correspondence files were reviewed for the period of 2008-2010. Although it appears that the facility did
not monitor for parameters not limited in the permit, they did not receive violations for this.

Subject: Draft renewal for Belhaven WTP, NC0086584
Attached is a copy of the draft renewal permit for the Belhaven WTP in Beaufort County. It should go out for Public
Notice on January 19. Please review it and send me any comments or questions.
The Belhaven WTP discharges to an UT to Pantego Creek. Upstream of the US 264 bridge is classified as C-NSW,
Sw and is not listed on the 2010 303(d) list. Downstream is classified as SC -NSW and is listed as impaired for
chlorophyll a and for copper. The planfs discharge has been considered to be to the salt water section and
limits were set accordingly. On this renewal, I reviewed the map included with the application and saw that the
discharge is actually to the freshwater section.
As a result of the change in classification of the receiving stream, and the results of the RPA conducted, some
changes have been made to the permit. They are:
• Monitoring requirements have been removed for chlorides due to lack of reasonable potential for this pollutant
to cause an exceedance of water quality standards.
• The limit has been removed for nickel; monitoring has been changed to quarterly as the result of EPA required
statistical analysis of DMR records.
• Monitoring for copper, fluoride, iron and zinc are changed to quarterly from monthly. Copper, Zinc and Iron all
have RP, but they are action level parameters and the plant has passed all WET tests, so no limits.
• Monitoring for turbidity has been added back to the permit in accordance with EPA requirements.
• The limits for pH have been changed to 6.0 S.U. to 9.0 S.U. from 6.5 S.U. to 8.5 S.U. This is due to a new
interpretation that the discharge is on the fresh water side of the highway 264 bridge

DENR - WATER QUALITY
POINT SOURCE BRANCH
The Town of Belhaven would like to formally request the renewal of its NPDES Permit
i NCO086584.i Enclosed is the complete pennit renewal application for The Town of
Belhaven's Water Treatment Facility. Along with this application you will find four
second species toxicity reports, a color coded drawing of the system processes and a
topographic map of the discharge from start to finish.
The facility is a ground water supplied Nano Filtration Drinking Water System and does
not produce waste solids, so at this juncture in time there is not a solids handling plan in
place.
Sincerely,
Town of Belhaav n, /WJTF

6. Description of source water(s) (i.e. groundwater, surface water)
groundwater
7. Describe the treatment process(es) for the raw water:
Water is drawn via two of three ground water wells at any given time at a rate of 400 GPM.
The well water has acid and a scale inhibitor added to convert the sulfides to carbonate
and prevent scaling of the membranes. The treated well water is then filtered by 5 micron
filters and forced through two separate skids containing thirty six Filmtec NF90-400
Membrane Elements per skid a two stage process where a 75% recovery process occurs.
100 GPM of waste water or 25% of the recovery process is sent to a field ditch in front of
our facility. This waste product contains minerals and inorganics concentrated by the
process, the PH level averages 7.0 su. 300 GPM of clean processed water (Permeate) is
further processed for human consumption. The permeate is mixed with 50 GPM of filtered
raw well water and then cascades through a degasifier ( to vent the sulfides to the
atmosphere). After the degasifier a corrosion control product is added to protect the
distribution lines from deterioration. Sodium Hypochlorite at 12.5% is added for
disinfection of the drinking water and 50% sodium Hydroxide is added to adjust the PH.
The water then fills a 300,000 Gallon holding tank for chlorine contact time and storage.
The water is then pumped to town for consumption.
S. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
The membrane facility generates waste water (concentrated well water) at a metered 100
GPM; 50 GPM per skid. As the well water is forced through the first stages of skid # 1 and
skid #2 the water becomes clean and seperates from the minerals and suspended particles
in the process sending the clean water through the center tubes in the middle of the
membranes and the concentrate or waste to the outside of the membrane away from the
permeate or clean water. At this point only 50% recovery has taken place. The waste
water from the first stage now enters the second and final stage where the water is
processed once more 25% going to the drinking water side and 25% going to the waste at
50 GPM per skid. After the consentrate or waste water exits the Water Treatment Facility
it discharges in a field ditch 100 feet from the facility where the water then flows south
towards Pantego Creek approximately 1.39 miles away from the facility. Along the way to
Pantego Creek the discharged concentrated well water is absorbed by the soil diluted by
rain water run off and evaporation. The treatment processes are all natural. It is only a
concentration of well water minerals and inorganics. This facility processes ground water
and produces no sludge or solids so as a result has no Solids Handling Plan.
9. Number of separate discharge points: 1.
