A. (2.) 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 TN Load (pounds/month) = TN x TMF x 8.34
where: TN = the average Total Nitrogen concentration (mg/ L) of the
composite samples collected during the month
TMF = the 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 (pounds/year) = Sum of the 12 Monthly TN Loads for the
calendar year
The Permittee shall report monthly Total Nitrogen results (mg/L and
pounds/month) in the appropriate discharge monitoring report for each month and
shall report each year's results (pounds/year) with the December report for that
year.
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 m /L x MG to pounds
A. (3.) 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 apply on a calendar year basis.
(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 discharge is less than or equal to its TN Load 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.

Permit NCO040606
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(l)(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:
https: / /www.federalregister.gov/ documents /2015 / 10 / 22 / 2015-24954 / national-pollutant-
discharge-elimmation-system-npdes-electron c -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
Page 7 of 9
Permit NCO040606
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:
