Subject: Issuance of NPDES Permit NCO007552
Freemason WTP
Chowan County
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject facility.
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.
The changes between this permit and the previous permit include the following:
• Flow limit has been removed.
• Total Iron and Total Lead are no longer required
• Added monthly turbidity monitoring.
• Effluent pl-1 monitoring is twice per month.
• Total Residual Chloride (TRC) limit is 17 pg/L. The Division shall consider TRC effluent values reported
below 50 µg/L to be compliant with the permit. However, the Permittee shall continue to record and submit
all values reported by a North Carolina -certified test method (including field certified), even if these values
fall below 50 µglL.
• Updated discharge stream segment to an unnamed tributary "Filbert Creek' to Edenton Bay [26-1 ] ,
currently a Class C; NSW waterbody with Subbasin 03-01-04 of the Chowan River Basin.
• The coordinates for the Outfall 001 are adjusted to the following:
Latitude: 36' 03' 52" LonlZitude: 76' 36' 50"
Whole Effluent Toxicity test results submitted during the past three years suggest that the Water Treatment Plant's
effluent is toxic to the receiving stream. As a result, the Town of Edenton shall perform a Discharge Alternatives
Evaluation (DAE) as described in Section A. (4.) of this permit. This evaluation is being requested to determine
whether there are any economical and technologically feasible alternatives available to the Town to comply with all NC
Water Quality Standards. The permittee will be given approximately one permit cycle to evaluate and document
possible treatment/discharge alternatives to eliminate aquatic toxicity. The evaluation shall be submitted with the
permittee's next permit renewal application and will be carefully reviewed by the Division and the results will be used
in the development of a compliance schedule or possible variance request for the Town.

Page 4 of 8

NPDES Pernnit NCO007552
A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING (QUARTERLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall
be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the
months of January, April, July and October. These months signify the first month of each three
month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be
obtained during representative effluent discharge and.shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
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
TGP3B. Additionally, DWR Form AT -I (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be fled with the Water 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
Water 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 this monitoring requirement or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, 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 monitoring.

A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports -(DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (standard Conditions for NPDES Permits):
• Section 13. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting [Supersedes Section D. (2.) and Section C. (5.) (a)1
Beginning no later than 270 days from the effective date of this permit, the permittee shall begin
reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring clata and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permitter is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be valid
for twelve (12) months and shall thereupon expire. At such time, DM Rs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.

Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.orWweb/wq/adminibc)ei ulp edmr
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the.
commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b)and supersedes Section B. (11.) (d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (I 1)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit

NPDES Permit NCO007552
A. (4.) DISCHARGE ALTERNATIVES EVALUATION:
The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity (WET) test failures.
This evaluation shall assess the feasibility of all the following alternatives.
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater
treatment plant. Approval or disapproval from the plant operator should be acquired.
2. Obtain a Non-discharfe permit: Eliminate the surface water discharge by obtaining a non -discharge
permit for spray irrigation, infiltration, or subsurface disposal (on -site drainijeld,
infiltration gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent to
consistently pass the WET test. If this is not technically feasible or cost prohibitive,
please explain and provide estimated costs.
4. Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest
County, City, or Town or other wells) so the discharge or toxicity problem is
eliminated.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment
methods or operational improvements that do not produce toxic wastewaters. For
example, install a recycle iron/manganese filtration system with no discharge or
combine discharge with WWTP or cooling water effluents.
6. Dischar<,e to a Lar;;er waterbodv/Perform a dilution model: Relocate the facility's discharge to a
larger receiving waterbody to eliminate or reduce toxic impacts to the receiving
waterbody given the increased dilution. If applicable, perform a dilution model to
receive allowance for stream dilution in WET test.
7. Combination of Alternatives: Employ any combination of the alternatives listed above that would
result in eliminating or decreasing toxicity until a more feasible solution becomes
available.
The evaluation shall include a present value of costs analysis for all technologically feasible options as
outlined in the Division's "Engineering Alternatives Analysis Guidance Document." This Document can be
found at: http://portal.ncdenr.orglweb/wq/sM//ps/npdes/permits.
This evaluation is being requested to determine whether there are any economical and technologically
feasible alternatives available to the Permittee to address aquatic toxicity in the plant effluent. Based upon the
evaluation, please identify viable alternatives and present an implementation schedule and project timeline
for the preferred alternative. The Permittee shall submit the Discharge Alternatives Evaluation to the
Division along with the submission of their next permit renewal application (due 6 months prior to permit
expiration on June 1, 2011) to:

Robbie,
Thanks for catching the type-o on the cover letter.
The water body or stream index according to what I'm seeing in ArcGIS is 26-1 with class C; NSW. Please see the
attached jpg files. The tributary Filbert Creed discharges to this segment, which is immediately downstream. The B;
NSW classification is upstream from there in Pembroke Creek. Part of the channel (squared off area) in Pembroke Creek
is actually C; NSW (not show on jpg). Everything on the Edenton Bay is C; NSW. The boundary between Pembroke
Creek and Edenton Bay is indicated on the facility map. It all depends on if you think it discharges to Pembroke Creek or
Edenton Bay. According the ArcGIS, my money is on Edenton Bay. Let me know what you think.
pH should have been 6-9 for freshwater.
TRC is 17mg/I because Filbert Creek has not been modeled or there is no 7Q10 as far as I know from BIMS or the
files. See attached spreadsheet.

The cover letter has City of Washington- should be Town of Edenton,
I noticed that in the supplement to permit cover sheet the waterbody classification has changed from B-NSW in the
existing permit to C-NSW. Was the last permit incorrect? This changed the PH and TRC limits.
The toxicity test changed from Chronic Ceriodaphania in the existing permit to Acute Mysid Shrimp in the new permit.
The fact sheet says it should be a pass/fail with Ceriodaphania. Footnote #15 states Ceriodaphania.

Robbie,
Thanks for catching the type-o on the cover letter.
The water body or stream index according to what I'm seeing in ArcGIS is 26-1 with class C; NSW. Please see the
attached jpg files. The tributary Filbert Creed discharges to this segment, which is immediately downstream. The B;
NSW classification is upstream from there in Pembroke Creek. Part of the channel (squared off area) in Pembroke Creek
is actually C; NSW (not show on jpg). Everything on the Edenton Bay is C; NSW. The boundary between Pembroke
Creek and Edenton Bay is indicated on the facility map. It all depends on if you think it discharges to Pembroke Creek or
Edenton Bay. According the ArcGIS, my money is on Edenton Bay. Let me know what you think.
pH should have been 6-9 for freshwater.
TRC is 17mg/I because Filbert Creek has not been modeled or there is no 7Q10 as far as I know from BIMS or the
files. See attached spreadsheet.
Permit Condition A. (2) should have been for Chronic Ceriodaphania.
Please see the attached corrected documents. Thanks for looking at the draft.
Thanks again,
Derek

Facility Summary
This facility is an ion exchange technology water treatment plant with discharge of wastewaters from media
filter backwash and sedimentation basins with a design potable flowrate of 1.350 MGD and a maximum,
monthly average wastewater discharge of 0.009 MGD based on data submitted. Because the waste flow is
<0.050 MGD, instantaneous monitoring is allowed. The facility consists of the following water and
wastewater treatment units:
well water supply systern
• aeration basin
• retention basin
• ion -exchange water -softener
• chemical usage consists of
o chlorine
a phosphate
o sodium chloride brine
Monthly average FLOW (MGD) — Last 36 months Jul2011-Jun2014:
[Ave 0.0085 MGD; Maximum, Monthly reported flow = 0.009 MGD]
Toxici —With an 1WC >0.25%, this permit requires Whole Effluent Toxicity (WET) testing using
Ceriodal)hnia.dubia to be performed as a 7-day pass/fail test at 90% effluent concentration, during
January, April, July and October [TGP3B]. Seven (7) out of twelve (12) (with a pass rate of 58.3%)
toxicity tests were reported as "FAIL" within three years (Ju1y201 I-Jun2014). A special condition [Section
I'act Sheet
Renewal 2014•-- NPDES Permit NCO007552
Page I

A.(4.)] is added for discharge alternatives evaluation because of the two (2) toxicity failures within the most
recent four (4) quarters. See attached data spreadsheet.
Renewal Summary --- This permit reflects discharge at Outfall 001 zind renewal strategy for WTI', revised
in 2009. DWR updated the facility description and Map; added parameter codes to Section A. (1.); added
I"IIcetronic Reporting - Discharge Monitoring Reports page [Section A. (3.)]; added monthly Turbidity
monitoring; removed flow limit, Total Iron and Total Lead; added 2/month sampling for effluent pl-l;
Total Residual Chlorine (TRC) limit was updated from 28µg/I, to 17}rgll., as a result ofdischarge to Tidal
tributary with no modeling or 7Q 10; and added Discharge Alternative Evaluation [Section A. (4.)]
because of TOX test failure within most recent four (4) quarters.
Sampling-- As with the previous permit, all'sampling is grab since flow is less than 30,000 Gl'D in
accordance with 15A NCAC 213.0505(C).
Stream — Discharge from W 1 P for Outfall 001 is into an unnamed tributary "Filbert Creek" to Edenton
Bay [Stream Segment .26-11. The segment [26-1] is not currently listed as impaired in the 2012 North
Carolina 303(d) List.
RPA — A Reasonable Potential Analysis (RPA) was conducted on Copper, Lead and Zinc effluent
parameters data becaUSe Discharge Monitoring Reports (DMRs) reported concentration above method -
detection levels (MDLs) for the past four and a half (4 ''/2) years (Jan20l O-Jarn2Ol4), unless otherwise noted).
[.See attached RPA summary sheets.] .
• Lead did not show reasonable potential to violate state WQS since the predicted maximum effluent
concentration was less than 50% of the allowable concentration monitoring will not be required.
• Iron did not show reasonable potential to violate state WQS since the predicted maximum effluent
concentration was less than 50% of the allowable concentration monitoring will trot he required
using two (2) years ol'data (July2012-June2014).

Fotenotes:
No later than 270 days from the effective date of this permit, begin submitting discharge monitoring reports electronically using NC DWR's eDMR application
system. See Special Condition A. (X.).
E = Effluent; I = Influent; U = upstream at least _ feet from the outfall; D = downstream at least _ feet from the outfall.
For instantaneous flow monitoring, the duration of the discharge must be reported in addition to the total flow.
The Division shall consider TRC effluent values reported below 50 µg/Lto be compliant with the permit. However, the Permittee shall continue to record and
submit all values reported by a North Carolina -certified laboratory method (including field certified), even if these values fall below 50µg/L.
For a given wastewater sample, TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahi Nitrogen, and NO3-N and NO2-N are Nitrate and
Nitrite Nitrogen, respectively effluent concentration, during January, April, July and October [See A. (X.)].
Whole Effluent Toxicity (WET) testing - testing of Ceriodaphnia dubia shall be performed as 7-day pass/fail test at 94% effluent concentration, during January, April,
July and October [See A. (X.)).
