Subject: DRAFT NPDES PERMIT NC0060259
Willow Oak MHP WWTP
Grade I Biological WPCS [15A NCAC 08G.0302]
Rockingham County
Dear Mr. Brown:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully
to ensure thorough understanding of the conditions and requirements it contains. Your permit is among
several in the Cape Fear River Basin that the Division has targeted for expedited renewal.
This draft contains the following changes from the existing permit:
➢ Ammonia Nitrogen(NH3-N)—The current permit requires monitoring twice monthly for NH3-
N, with effluent limits in place for summer months only. Recent review by Division staff has
noted that 15A NCAC 2B .0404(c)requires that winter waste load allocations for oxygen
consuming waste be no less stringent than 2 times the summer waste load limit. To meet this
rule requirement,winter limits for NH3-N must be added to the permit.The new winter
ammonia limits based on current EPA criteria are 35.0 mg/L daily maximum and 14.4 mg/L
monthly average.
➢ Facility Classification-The facility's classification was added above the effluent table.
➢ Electronic Reporting-The language in section A.(3)has been updated to be consistent with the
finalization of federal requirements for electronic reporting
The NPDES standard conditions(Parts II, III, and IV)that are a part of the permit are not included in this
draft document(cover,map,and Part I). The conditions are the same as in your current permit. The latest
version is available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
With this notification,the Division will solicit public comment on this draft permit by publishing a notice
in newspapers having circulation in the general Rockingham County area, per EPA requirements. Please
provide your comments,if any,to me no later than 30 days after receiving this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning the draft,please contact
me via email at [[e-mail]] or call 919-707-9125.
Sincerely,

A. (2) NUTRIENT REOPENER CONDITION
[NCGS 143-215.1 (b)]
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in the North
Carolina Administrative Code at 15A NCAC 2H.0112 (b)(1)and 2H.0114(a) and Part II sections B-12
and B-13 of this permit,the Director may reopen this permit to require supplemental nutrient
monitoring of the discharge. The purpose of the additional monitoring will be to support water quality
modeling efforts within the Cape Fear River Basin and shall be consistent with a monitoring plan
developed jointly by the Division and affected stakeholders. In addition, the results of water quality
modeling may require that limits for total nitrogen and total phosphorus be imposed in this permit upon
renewal.
A. (3) 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.) (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
broadband
physically located in an area where less than 10 percentof the households have broadba d
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.
Page 4 of 6

Permit NC0060259
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(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:
