A.(2) ELECTRONIC REPORTING-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. (5.) (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. The eDMR system
may be accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.
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 following address:
NC DEQ/Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
See"How to Request a Waiver from Electronic Reporting"section below.
Monitoring results obtained during the previous month(s)shall be summarized for each month
and reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. 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 21,2025,the permittee must electronically report the following
compliance monitoring data and reports,when applicable:

Permit NC0020478
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:
https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pol lutant-
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
