NPDES Permit N00036684
A. (2.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G. S . 143-215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division adopted
these regulations in 2013.
NOTE: This special condition supplements or supersedes the following sections within Part H 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 [Supersedes Section D. (2.) and Section E. (5.) (a)]
Beginning no later than 270 days from the effective date of this permit, 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 / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
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.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
Page 4 of 5

NPDES Permit NC0036684
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http: //uortal.ncdenr. org/web/wq/admin/bo IZ/ipu/edmr
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.
2. Signatory Requirements (Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
II, Section B. (I 1.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (I 1.)(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:
httD://vortal.ncdenr.org/web/Wo/adminiboa/ilDu/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. "
3. Records Retention [Supplements Section D. (6.)1
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].

Facility Summary
This facility is a minor residential facility (flow <1 MGD) that receives 100% domestic waste from 304
homes. The design capacity of the treatment system is 0.1MGD. No significant changes have been made to
this facility since the last permit renewal.
The facility consists of the following wastewater treatment units:
• dual extended aeration basins
• final clarifiers with sludge return
• tablet chlorination with tablet dechlorination
• post -aeration
• sludge digester
Monthly average FLOW (MGD) — Last 36 months Ju12012-Jun2015:
[Ave 0.033 MGD; Maximum, Monthly average flow = 0.057 MGD]
Toxici — Not required
Renewal Summary— This permit reflects discharge at Outfall 001. DWR updated the following:
• updated the facility description (see supplement to cover sheet) and Map
Fact Sheet
Renewal 2015 -- NPDES Permit NCO036684
Page 1

• the coordinates for the Outfall 001 were adjusted to the following as indicated on the facility map
attached to the application:
Latitude: 35' 30' 14" Longitude: 82' 36' 38"
• added parameter codes to Section A. (L)
• added DO limit to the effluent table which replaces the footnote
• added Electronic Reporting - Discharge Monitoring Reports page [Section A. (2.)].
Stream — Discharge from Bent WWTP for outfall 001 is into Wesley Creek (Bent Creek Ranch Lake)
[Stream Segment 6-67-10]. The segment is not listed as impaired in the 2014 North Carolina Integrated
report.
RPA — A Reasonable Potential Analysis (RPA) was not applicable for any parameters for this permit
renewal.
Implementation of 2012 Statewide Mercury TMDL — Bent WWTP was not required to sample for mercury
in the previous permit. Monitoring for Mercury is not required for this permit because it does not serve a
municipality. The renewal application indicated "residential" for the facility generating wastewater and
"separate (sanitary sewer only)" for type of collection system. The WWTP serves Saddle Creek —
Subdivision which is a gated residential community with 304 homes (760 population). The facility does not
serve any industries or dental offices.
