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.) 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:
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.
Page 4 of 7

Permit NC0028975
Grade II Biological Water Pollution Control System [15A NCAC 08G.0302]
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://www2.epa.gov/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 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

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://deq.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR
system shall make the following certification [40 CFR 122.22]. 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."
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].

A. (3) EFFLUENT MERCURY ANALYSIS
[G.S. 143-215.66]
