Subject: Draft NPDES Permit Renewal
Permit NCO069311
Franklin County WWTP
Franklin County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Doherty:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
• Per 15A NCAC 08G .0302, the facility class has been changed to Grade IV due to the
nutrient limits in the permit and the rule conditions [See A.(1.)].
• As the facility class has been updated, monitoring frequencies for BOD5, ammonia, TSS,
fecal coliform, dissolved oxygen, temperature, pH, and conductivity have bden revised to
reflect a Grade IV facility [See A.(1.)].
• Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards, the monitoring requirement for total zinc has been
removed from the permit [See A.(1) and A.(2.)].
• Based on the reasonable potential analysis (RPA) predicting a maximum effluent total lead
concentration that is greater than half of the allowable discharge concentration based on
state water quality standards, quarterly monitoring for total lead has been added to the
permit [See A.(1) and A.(2.)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards, total copper and total cadmium limits have been added to the
permit and the quarterly monitoring requirement has been changed to monthly monitoring
[See A.(1) and A.(2.)].
• The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the
NC Environmental Management Committee (EMC) on November 13, 2014. The US EPA
subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC
Division of Water Resources NPDES Permitting Unit is required to implement the new
dissolved metal standards in all permits public noticed after April 6, 2016. The new
standards for most metals include acute standards. Further, the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have
hardness -dependent equations. As a result, the NPDES Permitting Unit will need site -
specific effluent hardness data and instream hardness data, upstream of the discharge, for
North Carolina Department of Environmental Quality I Division of Water Resources

each facility monitoring these metals in order to calculate permit limitations. Effluent
hardness and instream hardness sampling, upstream of the discharge, have been added to
the permit at a monitoring frequency of quarterly [See A.(1.)].
• Franklin County Public Utilities reported Total Selenium and Total Silver at less than
detection, with detection levels < 10.0 µg/L, and < 5.0 µg/L respectively, in the Effluent
Pollutant Scans (or their DMR results). The Town's allowable discharge concentrations
are 7.6 µg/L and 0.091 µg/L for Total Selenium and Total Silver, respectively. DWR's
laboratory identifies the target Practical Quantification Limit (PQL) for both Total
Selenium and Total Silver as 1.0 µg/L. 15A NCAC 2B .0505 (e) (4) requires that all test
procedures must produce detection and reporting levels that are below the permit discharge
requirements and all data generated must be reported to the approved detection level or
lower reporting level of the procedure. If no approved methods are capable of achieving a
detection level below the permit discharge requirement (or allowable discharge
concentration) the method with the lowest detection level must be used. The County should
use sufficiently sensitive test methods for all pollutants, including when performing
Effluent Pollutant Scans.
• Some of the wording has changed in Special Condition A.(7.), Chronic Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A.(8.) has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed (2022, 2023, and 2024). In addition, at the end
of the Special Condition, 2°d species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.210)(5)] have been added.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The requirement to continue reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR)
internet application has been added to your NPDES permit [See Special Condition A.(9.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A. (1.) and A.(2.)].
• Regulatory citations have been added to the permit.
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included
in this draft document (cover, map, and Part I). The conditions are the same as in your current
permit except that agency and division names have been updated. The latest version is available at
https://bit.ly/3k5NFaL and can be viewed online or downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having
circulation in the general Franklin County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following: NCDEQ/DWR, NPDES
Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 no later than 30 days
after receipt of this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments
and take appropriate action prior to issuing a final permit. If you have questions concerning this
draft permit, please call me at [phone] or by email at [e-mail].

Page 6 of 16

Permit NCO069311
A.(4.) CALCULATION OF TOTAL NITROGEN AND TOTAL PHOSPHORUS LOADS
[G.S.143-215.1(b)]
a. The Permittee shall calculate monthly and annual TN Loads as follows:
(i.) Monthly TN (or TP) Load (lb/mo) = TN (or TP) x TMF x 8.34
where:
TN or TP = the average Total Nitrogen or Total Phosphorus concentration
(mg/L) of the composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month (MG/ mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
(ii.) Annual TN (or TP) Load (lb/yr) = Sum of the 12 Monthly TN (or TP) Loads for the
calendar year
b. The Permittee shall report monthly Total Nitrogen and Total Phosphorus results (mg/L and lb/mo)
in the appropriate discharge monitoring report for each month and shall report each calendar year's
results (lb/yr) with the December report for that year.
A.(5.) ANNUAL LIMITS FOR TOTAL NITROGEN OR TOTAL PHOSPHORUS
[G.S.143-215.1(b)]
a. Total Nitrogen (TN) and Total Phosphorus (TP) allocations and load limits for NPDES
dischargers in the Tar -Pamlico River basin are annual limits and apply on a calendar year basis.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN (or TP)
Load limit in this Permit if:
(i.) the Permittee's annual TN (or TP) Load is less than or equal to the effective limit, or
(ii.) the Permittee is a Co-Permittee Member of a compliance association.
C. If the Permittee is not a co-permittee member of a compliance association and the Permittee's
cumulative annual TN (or TP) discharge exceeds the effective TN (or TP) Load limit in this permit
at any point during the calendar year, the Permittee is in violation of its TN (or TP) Load limit for
the remainder of the calendar year, and each day of continuing violation shall constitute a
separate violation. Compliance with annual limits shall be determined separately for each
calendar year, and an exceedance in one year does not carry forward to subsequent years.
d. The TN (or TP) Load limit in this Permit (if any) may be modified as the result of allowable
changes in the Permittee's allocations.
(i.) Allowable changes include those resulting from purchase of TN (or TP) allocation from an
authorized mitigation banker, the Ecosystem Enhancement Program, or other source
allowed under applicable regulations; purchase, sale, trade, or lease of allocation between
the Permittee and other dischargers; and other transactions approved by the Division and
consistent with the Tar -Pamlico River Basin Association Agreement, as revised.
(ii.) The Permittee may request a modification of the TN (or TP) Load limit in this Permit to
reflect allowable changes in its allocation(s). Upon receipt of timely and proper application,
the Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
(iii.) Changes in TN (or TP) limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
(iv.) Application shall be sent to:

Permit NC0069311
NCDWR / Wastewater Permits Branch
Attn: Tar -Pamlico River Basin Coordinator
1617 Mail Service Center
Raleigh, NC 27699-1617
e. If the Permittee is a member and co-permittee of an approved compliance association on January
1 of a given year, its TN and TP discharges during that year are governed by that association's
group NPDES permit and the limits therein.
(i.) The Permittee shall be considered a Co-Permittee Member for any given calendar year in
which it is identified as such in Appendix A of the association's group NPDES permit.
(ii.) Association roster(s) and members' TN and TP allocations will be updated annually and in
accordance with state and federal program requirements.
(iii.) If the Permittee intends to join or leave a compliance association, the Division must be
notified of the proposed action in accordance with the procedures defined in the
association's NPDES permit.
(A) Upon receipt of timely and proper notification, the Division will modify the permit as
appropriate and in accordance with state and federal program requirements.
(B) Membership changes in a compliance association become effective on January 1 of the
year following modification of the association's permit.
f. The TN and TP monitoring and reporting requirements in this Permit remain in effect throughout
the term of the Permit and are not affected by the Permittee's membership in a compliance
association.
A.(6.) NUTRIENT ALLOCATIONS
[G.S.143-215.1(b)]
a. Total Nitrogen (TN) and Total Phosphorus (TP) allocations represent the maximum TN and TP
loads that a discharger or group of dischargers is potentially allowed under the Tar -Pamlico
nutrient management strategy. Allocations are not enforceable limits but are the basis for TN and
TP limits established in individual or group NPDES permits.
b. The allocations originally assigned to the Tar -Pamlico Basin Association members total 889,274
lb/yr (404,274 kg/yr) TN and 160,372 lb/yr (73,060 kg/yr) TP. These group allocations have been
divided among the members in proportion to the maximum permitted flow in each member's
permit; that is,
Individual Permitted Flow
Individual Allocation (TP or (MGD) x Group Allocation, TPBA (TN
TN) = Total Permitted Flow, TPBA or TP)
(MGD)
For the purposes of this distribution, individual permitted flows for the Association members are those
in effect as of July 2014 and result in a Total Permitted Flow of 62.495 MGD.
C. The following table lists, for information purposes only, the TN and TP allocations assigned to,
acquired by, or transferred to the Permittee in accordance with the Tar -Pamlico River Basin Phase
IV Agreement. Applicable TN or TP limits are established in the Effluent Limitations conditions
of this permit or in the NPDES permit of a compliance association of which the Permittee is a Co-
Permittee Member.

[15A NCAC 02B .0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 66% at 2.0 MGD and 74% at 3.0 MGD.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. 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.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered electronically using
the Divisions eDMR system for the months in which tests were performed, using the parameter code
TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3
(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
Or, results can be sent to the email, [e-mail].
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, accurate, include all supporting chemical/ physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved
designate signature. 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,
monitoring will be required during the following month. Assessment of toxicity compliance is based on
the toxicity testing quarter, which is the three month time interval that begins on the first day of the
month in which toxicity testing is required by this permit and continues until the final day of the third
month.
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.

d. Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that
Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are
also subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR
122.210)(5). The US EPA requires four (4) toxicity tests for a test organism other than the test
species currently required in this permit. The multiple species tests should be conducted either
quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests
performed at least annually in the four and one half year period prior to the application. These
tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. The
multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at the
following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Or, results can be sent to the email, [e-mail].
Contact the Divisions Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting
the additional toxicity tests and reporting requirements. Results should also be summarized in
Part E (Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the
permit renewal application to the NPDES Permitting Unit.
A.(9.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S.143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report 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
Page 12 of 16

Permit NC0069311
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: https:/ /deq.nc.gov/about/divisions/water-resources/edmr.
If a permittee 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 following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
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.
Starting on December 21, 2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated
entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
hops://www.federalre ig ster.gov/documents/2015/10/22/2015-24954/national-vollutant-
discharge-elimination-system-npdes-electronic-reporting rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.

Permit NC0069311
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers 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 submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver
request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
hft://deg.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)]
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 I1,
Section B. (11.)(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
Carolinas eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
ht!p://deq.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make
the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL
BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my direction or
supervision in accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or
those persons directly responsible for gathering the information, the information submitted is, to the best of
my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for
submitting false information, including the possibility of fines and imprisonment for knowing violations."
5. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years from the
date of the report. This period may be extended by request of the Director at any time [40 CFR
122.41].
