Class WW-4
A. (3.) 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 (lbs/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 (lbs/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
lbs/mo) in the appropriate discharge monitoring report for each month and shall report each
calendar year's results (lbs/yr) with the December report for that year.
A. (4.) 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 comply 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
Page 5 of 13

Permit NC0020605
Class WW-4
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:
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. (5.) 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.
Page 6 of 13

Permit NC0020605
Class WW-4
(b.) The allocations originally assigned to the Tar-Pamlico Basin Association members total
889,274 lbs/yr(404,274 kg/yr) TN and 160,372 lbs/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(MGD) x Group Allocation,TPBA(TN or
Individual Allocation(TP or TN)= Total Permitted Flow,TPBA 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.

typographical errors) or any change from Reserve to Active status of any of the listed
allocations shall be considered a major modification of this permit and shall be subject to
the public review process afforded such modifications under state and federal rules.
A. (6.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[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 8 %.
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
Page 7 of 13

Permit NC0020605
Class WW-4
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 a 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 on the Effluent
Discharge Monitoring Form (MR-1) 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,NC 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, 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.

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
122.21(j)(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(41/2)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
1623 Mail Service Center
Raleigh, North Carolina 27699-1623
Contact the Division's 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. (8.) ELECTRONIC REPORTING - DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports and specify that, if a state does not establish a system to receive such submittals,
then permittees must submit monitoring data and reports electronically to the Environmental
Protection Agency(EPA). 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
Page 10 of 13

Permit NC0020605
Class WW-4
1. Reporting Requirements [Supersedes Section D.(2.) and Section E.(5.) (a)1
Effective December 21, 2016, 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 monitoring data 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/ Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
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 mailing address above. 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, 2020, 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.
Page 11of13

Permit NC0020605
Class WW-4
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: http://www2.epa.gov/compliance/final-
national pollutant-discharge-elimination-system-npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
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: http://4eq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B.(11.)(b)and Supersedes Section B.(11.)(d)1
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. (11.)(b). A person, and not a position,must be delegated signatory
authority for eDMR reporting purposes.
