Subject: Issuance of NPDES Permit NCO088340
Pamlico County Water System
Mill Pond Water Treatment Plant (WTP)
Pamlico 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 draft permit include the following:
The due date for Special Condition was corrected to November 30, 2017 (6 months prior to permit
expiration).
The changes between this permit and the previous permit include the following:
• All sampling is grab since flow is less than 30,000 GPD in accordance with 15A NCAC 2B.0505(C).
• Added Total Manganese sampling according to the latest permitting strategy.
• Removed limit for Total Phosphorous (TP).
• Removed Total Lead Monitoring.
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 Permittee 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 Permittee 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 Permittee.
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.

Page 4 of 8

NPDES Permit NCO088340
A. (2.) ACUTE TOXICITY PASS/FAIL 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 -December 2010 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). The tests will be performed during the months of March, June, September and
December. 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
TGUE. Additionally, DWR Form AT-2 (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 filed 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 either these monitoring requirements 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 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.

NPDES Permit NCO088340
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 -discharge permit: Eliminate the surface water discharge by obtaining a non -discharge
permit for spray irrigation, infiltration, or subsurface disposal (on -site drain_field,
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. Discharge to a Larger waterbody/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.org/web/wq/swp/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 November 30, 2017) to:

Fact Sheet
Renewal 2014 -- NPDES Permit NCO088340
Page 1

Renewal Summary — This permit reflects discharge at Outfall 001 and renewal strategy for WTP, revised
in 2009. DWR updated the facility description and Map; added parameter codes to Section A. (1.); added
Electronic Reporting - Discharge Monitoring Reports page [Section A. (3.)]; removed limits for Total
Phosphorus; removed Total Lead monitoring; changed all sampling to Grab; added total Manganese; and
added Discharge Alternative Evaluation [Section A. (4.)] because of TOX test failure within most recent
four (4) quarters.
Toxici — With a Tidal discharge that is not modeled, this permit requires Acute Whole Effluent Toxicity
(WET) testing using Mysidopsis Bahia to be performed as 24-day pass/fail test at 90% effluent
concentration, during March, June, September and December [TGE3E]. Three (3) out of twelve (12)
(with a pass rate of 75%) toxicity tests were reported as "FAIL" within three years (July2010-Jun2014). A
special condition [Section A.(4.)] is added for discharge alternatives evaluation because of the two (2)
toxicity failure within the most recent four (4) quarters. See attached data spreadsheet.
Sampling — All sampling is grab since flow is less than 30,000 GPD in accordance with 15A NCAC
2B.0505(C).
Stream — Discharge from WTP for Outfall 001 is into an unnamed tributary North Prong Bay River
[Stream Segment 27-150-2]. This segment is not currently listed as impaired in the 2012 North Carolina
303(d) List.
Total Phosphorus (TP) — TP was limited in the previous permit with a quarterly average of 2.0 mg/L.
According to the nutrient monitoring strategy for the Neuse River Basin TP is to "Monitor & Report".
For TP — Last 4 %2 years Feb2010-Ju12014: [Ave = 0.12 mg/L; Maximum = 0.62 mg/L]
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 V2) years (Feb2010-Ju12014), unless otherwise noted).
[See attached RPA summary sheets.]
• Lead (Aug2012-Ju12014) did not show reasonable potential to violate state WQS and the predicted
maximum effluent concentration was less than 50% of the allowable concentration. Monitoring will
no longer be required.

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.).
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/L to 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 SOµg/L
For a given wastewater sample, TN =TKN +NO3-N+ NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl 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 Mysidopsis bahia shall be performed as 24-day pass/fail test at 90%effluent concentration, during January, April, July and
October [See A. (x.)].

Re: NPDES Permit NCO088340 Renewal Application
Dear Mr. Thedford
ID �� n
DEC 2 0 2013
oENR-A7-,
Please find enclosed one signed original and two copies of the completed application
for renewal of the Millpond WTP NPDES permit. Our current permit NCO088340
expires June 30, 2014.
Please note that all the discharge under the current permit is generated from this water
treatment plant. The backwash water produced comes from 2 iron filters and 2 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. Al Gerard at 252-745-
5453.
Sincerely,
n
