The Division has reviewed your request to renew the subject permit. Please review this draft
carefully to ensure your thorough understanding of the information, conditions, and
requirements it contains.
The draft permit includes the following significant changes from the existing permit:
➢ Section A. (6.) has been added to require electronic submission of effluent data.
Federal regulations require electronic submittal of all discharge monitoring
reports (DMRs).
➢ Regulatory citations have been added to the permit.
➢ An updated outfall map has been included.
Please note that the Neuse River is listed as an impaired waterbody on the North Carolina

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 TN Load (pounds/month) = TN x TMF x 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 (pounds/year) = Sum of the 12 Monthly TN Loads for
the calendar year
b. The permittee shall report monthly Total Nitrogen results (mg/L and
pounds/month) in the discharge monitoring report for that month and shall
report each year's annual results (pounds/year) in the December report for that
year.
A. (4.) ANNUAL LIMITS FOR TOTAL NITROGEN
[G.S. 143-215.1(b)]

Permit NCO056618
(c) TN limits for NPDES dischargers in the Neuse River basin are annual, calendar -
year limits. All such limits in effect on January 1 of a given year remain in effect
for the entire calendar year. Changes in TN limits become effective on January 1
of the year following permit modification and remain in effect for the full year.
Similarly, changes in membership in a compliance association become effective
on January 1 of the year following the change and remain in effect for the full
year.
(d) For any given calendar year, the permittee shall be in compliance with the
annual TN Load limit in this permit if:
(1) the permittee's annual TN Load is less than or equal to said limit, or
(2) the permittee is a member of a compliance association and a co -permittee to
the association's group NPDES permit.
(e) The permittee's effective TN limit (if any) may change due to changes in its TN
allocation or membership changes in a compliance association.
(1) The permittee may notify the Division and request a modification of this
permit to incorporate allowable changes in its TN Load limit. 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.
(2) If the permittee intends to join or leave a compliance association, the Division
must be notified of the proposed change.
(3) Upon receipt of timely and proper notification, the Division will modify the
affected permit(s) as necessary to incorporate the allowable changes in TN
limits or to reflect the change in membership.
a. The Division must receive notification no later than August 31 for changes
proposed for the following calendar year.

A. (6.) 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.
NOTE: This special condition supplements or supersedes the following sections within Part
II of this permit (Standard Conditions for NPDES Pennits):
• 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.) (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
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:

Permit NCO056618
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(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- elimination- system-npdes- electronic -reporting -rule 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 • / / deq nc gov /about/ divisions/water-resources / edmr
