Permit NCO086983
A. (2.) 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. J5.j (a►1
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.
Page 4 of 7

Permit NCO086983
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: http • / / wm w2 epa g_ov / 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
Page 5 of 7

Permit NCO086983
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://de!g.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.
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 Carolina's eDMR system, registering for eDMR and
obtaining an eDMR user account, please visit the following web page:
http: / /deg.nc.govZabout/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR
system shall make the following certification [40 CFR 122.221. 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. "
Page 6 of 7

Permit NCO086983
5. Records Retention [Supplements Section D.
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 ] .
