Dear Mr.Konsul:
The Division has reviewed your request to renew the subject pennit. Please review this draft carefully to ensure a
thorough understanding of the information,conditions,and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
i% Ammonia Nitrogen limits were adjusted based on the results of the waste load allocation spreadsheet and
to remain consistent with the Division's 1999 ammonia policy for minor facilities discharging< 1 MGD
and the Division's updated 2016 ammonia criteria.A review of the DMR data during the previous permit
cycle indicates that the facility can meet these updated permit limits.
r Section A.(2)has been updated regarding electronic submission of effluent data.Federal regulations
require electronic submittal of all discharge monitoring reports(DMRs).
Please note that North Fork Crooked Creek is listed as an impaired waterbody on the North Carolina 303(d)
Impaired Waters List. Addressing impaired waters is a high priority with the Division,and instream data will
continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be
mitigativemeasures maybe required.
attributed to your facility,then nutlga 1 q
With this notification,the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Union County area,per EPA requirements.Please provide your
comments,if any,to me no later than 30 days after receiving this draft permit.

NPDES Permit NC0035041
Footnotes:
1. The pennittee shall submit discharge monitoring reports electronically using the Division's eDMR
system[see A. (2)].
2. U: upstream 100 feet above the outfall. D: downstream 200 feet below the outfall.
3. 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.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM OTHER THAN
TRACE AMOUNTS.
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)l
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 pennittee 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, 1.1,1 3)or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
following address:

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:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports;and
• Clean Water Act(CWA)Section 316(b)Annual Reports.

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-t ollutant-discharge-elimination-system-nodes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the"Reporting Requirements"section
above.

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

reporting waiver request is effective.
