Footnotes:
1. Submit discharge monitoring reports electronically using the NC DWR's eDMR application system [See
section A. (2.)].
2. Flow shall be monitored with each discharge event. During periods of no flow, the Permittee shall submit
a signed, monthly Discharge Monitoring Report (DMR) indicating "No discharge." Flow may be monitored
using any one of four methods:
a) Measure flow continuously
b) Calculate flow (see Rational Equation below) based on total rainfall per unit
area draining to the outfall; exclude built -upon areas (best method for facilities
with large runoff -collection ponds)
The Rational Equation: Q = KuCIA, where:
Q = flow (peak flow rate (cfs or ms/sec)
Ku = units conversation factor =1.008 for U.S. standard units (usually ignored
because it is so close to 1), or 0.278 for SI units
C = dimensionless runoff coefficient for the watershed, loosely defined as
the ratio of runoff to rainfall
I = intensity of rainfall taken from the intensity -duration -frequency curves
for the specified design return period at the time of concentration, tc
(in/h or mm/h). tc = time of concentration (time after the beginning of
rainfall excess when all portions of the drainage basin are contributing
simultaneously to flow at the outlet).
A = area of tributary watershed (acres or km2)
The rational equation is used to calculate the runoff from a region, given:
i) the runoff coefficient which accounts for infiltration and other
potential losses in the region
ii) the rainfall intensity to the region
iii) the time it takes for runoff to travel from the region's upper reaches to
its outlet
iv) the region's drainage area

Permit NCO049905
c) Estimate flow at 20-minute intervals during the entire discharge event
d) Report flow based on discharge pump logs
3. Effluent monitoring and limitation only apply if chlorine or a chlorine derivative is added to the waste stream
during treatment. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance
with the permit. However, the Permittee shall continue to record and submit all values reported by a North
Carolina certified laboratory (including field certified), even if these values fall below 50 µg/L.
4. Oil and grease samples shall be skimmed from the surface of a quiescent (calm water) zone.
5. The discharge from this facility shall not cause turbidity in the receiving stream to exceed 50 NTU. If the instream
turbidity exceeds 50 NTU due to natural background conditions, the discharge cannot cause turbidity to increase
in the receiving stream. Therefore, if the effluent measurement exceeds 50 NTU, the Permittee shall sample
upstream and downstream turbidity in the receiving waterbody, within 24 hours, to demonstrate the existing
turbidity level in the receiving waterbody was not increased. All data shall be reported on the DMRs. (See 15A
NCAC 2B .0211 (21)).
6. The temperature of the effluent shall be regulated so as not to cause an increase in the temperature of the receiving
stream of more than 2.8°C and in no case cause the ambient water temperature to exceed 32°C.
The permittee shall obtain authorization from the Division prior to the use of any chemical additive in the
discharge. The permittee shall notify the Director in writing at least ninety (90) days prior to instituting use
of any additional additive in the discharge which may be toxic to aquatic life (other than additives previously
approved by the Division). Such notification shall include completion of Biocide Worksheet 101 (if
applicable), a copy of the MSDS for the additive, and a map indicating the discharge point and receiving
stream.
There shall be no chromium, zinc, or copper added to the discharge except as pre -approved additives
to biocidal compounds.
All samples collected should be from a representative discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

A. (8) ELECTRONIC REPORTING OF 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.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting
Records Retention
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. 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, 2025, 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).
Page 5 of 8

Permit NC0049905
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.federalre ig ster.gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-elimination-
system-npdes-electronic-reporting.
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
4. Signatory Requirements [Supplements Section B. (11.) (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 11, 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:
httn: Hdeo .nc. cov/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:
7 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
Page 6 of 8

Permit NCO049905
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.)]
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 ].
