Subject: Review of DRAFT NPDES Permit NC0088048
Stonegate Mobile Home Park (MHP)
Potable Water Treatment Plant (WTP), WPCS Grade PCNC
1311 Curtis Bane Road
Orange County
Ms. Bane:
The Division of Water Resources (DWR or the Division) received on February 8, 2021 your application
to renew the subject permit. Please carefully review the attached renewal draft to ensure your
understanding of its limits and monitoring conditions, and to correct errors, if any.
Concurrent with this notification, the Division will solicit public comment on this draft by publishing a
notice in newspapers having circulation in the general Durham County area, as required by the NPDES
Program. Please submit your written comments (if any), to my attention, NCDEQ / DWR / NPDES no
later than July 28, 2023 (approximately 30 days after receiving this document).. We welcome your
written comments, but they are not mandatory.
The Division understands that you have made no significant alterations to treatment-systems
or processes since last renewal. Therefore, we have made only minimal updates to your permit
for renewal such as site-vicinity map and facility description (see Supplement to Permit Cover
Sheet), and eDMR instruction text [section A. (2.)]. We have also discontinued monitoring for
Turbidity.
Note that your facility is not currently eligible for the WTP General Permit NCG590000 (NCG59)
because the Neuse River Basin Permitting Strategy requires specific tasks not possible under the General
Permit, namely your need to monitor Total Nitrogen (TN) and Total Phosphorus (TP).
Monthly Report Submittals: Federal regulations require electronic submittal of all program reports
and Monthly Discharge Monitoring Reports (DMRs); see Permit Condition A. (2.). Our records
show that you have successfully registered for the Electronic Discharge Monitoring Report
(eDMR) program. If you have completed and submitted to DWQ an Electronic Signature
Agreement, you are no longer required to submit DMR hardcopy as back-up to the eDMR.
The NPDES standard conditions (Parts II, III, and IV), are part of this permit but are not included in this
draft document (cover, map, and Part I only). The conditions are identical to your current permit except
that agency and division names have been updated. The latest version of Parts II, III, and IV are available
at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
Emily Bane, Manager
Permit Renewal - Draft Review
Jun2023
Following the mandatory 30-day Public Comment period, the Division will review all pertinent comments,
if any, and take appropriate action prior to issuing an NPDES permit final.
If you have questions, please email the undersigned at [joe.corporon@ncdenr.gov]. In support of mandated
emergency response to Covid 19, most of NC state government currently functions remotely, therefore
correspondence via email is preferred.
Respectfully,

A. (2.) ELECTRONIC REPORTING OF DISCHARGE 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.) (a)]
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
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).
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.
Permit NC0088048
Page 5 of 6
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-
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
Signatory Requirements [Supplements Section B. (11.) (b) & 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 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."
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].
