A. (2) ELECTRONIC REPORTING OF 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 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
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 DEQ / 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
Page 4 of 6

Permit NC0087645
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:
http: /, /www2. epa. gov / compliance / fmal-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:
httb: / / dea.nc. izov / about/ divisions /water -resources / edmr
4. Simatory Requirements [Supplements Section B. (11.1 (b) and Supersedes Section B.
(11.) (d)]
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 H, 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:

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. "
5. Records Retention [Supplements Section D. (6.11
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].
