A. (3.) CALCULATION OF TOTAL NITROGEN LOADS
[G.S. 143-215.1(b)]
a. The permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly Total Nitrogen (TN) Load (lbs/month) = TN x TMF R 8.34
Where:
TN = average TN concentration (mg/ L) of the composite samples collected
during the month
TMF = Total Monthly Flow of wastewater discharged during the month
(MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (lbs/year) = Sum of the 12 Monthly TN Loads for the calendar
year
b. The permittee shall report monthly Total Nitrogen results (mg/L and lbs/month) in the
discharge monitoring report for that month and shall report each year's annual results
(lbs/year) in the December report for that year.
A. (4.) ANNUAL LIMITS FOR TOTAL NITROGEN
[G.S. 143-215.1(b)]
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse
River basin are annual limits and are applied for the calendar year.
b. For any given calendar year, the permittee shall be in compliance with the annual TN Load
limit in this permit if:
i. the permittee's annual TN Load is less than or equal to said 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 discharge exceeds the effective TN Load limit in this
permit at any point during the calendar year, the Permittee is in violation of its TN Load
limit, and each day of a continuing violation shall constitute a separate violation.
d. The TN Load limit in this permit (if any) may be modified as the result of allowable changes
in the permittee's TN allocation.
i. Allowable changes include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the
permittee and other dischargers; regionalization; and other transactions approved by
the Division.
ii. The permittee may request a modification of the TN Load limit in this permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application,
the Division will modify the permit as appropriate and in accordance with state and
federal program requirements.
Hi. Changes in TN 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.

Permit NCO062219
A. (6.) TEMPORARY MEANS OF DISINFECTION
[NCGS 143-215. 1 (a)]
In the event that the wastewater treatment plant's ultraviolet (UV) disinfection system should
fail, under -perform, or otherwise be removed from effective service, the permittee or his agent
should immediately inform the Surface Water Protection Section staff of the Raleigh Regional
Office (919/791-4200) of this development and discuss temporary, alternate means for
disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection, the total residual
chlorine (TRC) concentration of the effluent must be monitored on a daily basis while this
method of disinfection is in use and values must be reported on the discharge monitoring
report. TRC in the effluent may not exceed 28 µg/L; therefore, dechlorination methods may
also be necessary to ensure protection of water quality in the receiving stream.
The Division shall consider all effluent TRC values reported below 50 µg/L to be in
compliance with the permit. However, the Permittee shall continue to record and submit all
values reported by a North Carolina certified laboratory (including field certified), even if
these values fall below 50 µg/ L.
Use of a disinfection system other than the permitted UV system during circumstances not
deemed as emergency and/or temporary (replacement of lamps, lamp cleaning or
maintenance, etc.) will be considered a violation of the terms of this permit.
A. (?.) 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 90.0%.
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 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 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 -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean
of the highest concentration having no detectable impairment of reproduction or survival and
the lowest concentration that does have a detectable impairment of reproduction or survival.
The definition of "detectable impairment," collection methods, exposure regimes, and further
statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity
Test Procedure" (Revised -February 1998) or subsequent versions.
Page 9 of 14

Permit NCO062219
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: NC DENR / DWR / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch
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 Environmental Sciences Branch 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. 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, m 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. (8.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 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.

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. (2.1 and Section E. (5.1 (all
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

Permit NC0062219
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.
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:

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.
