Dear Mayor. Scott:
The Division has reviewed your request to renew the subject permit.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:
> Section A. (3)has been updated regarding electronic submission of effluent data. Federal regulations
require electronic submittal of all discharge monitoring reports(DMRs).
➢ Regulatory citations have been added to the permit.
➢ Parameter codes have been updated.
> Removed Mercury Special Condition section,updated in footnotes.
Please note that Butterwood 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 attributed to
your facility,then mitigative measures may be required.
With this notification,the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Halifax 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 at

Nutrient Sensitive Waters(NSW)Implementation Strategy: Phase III adopted April 14,2005.Non-members of

A. (3.) 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 [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)intemet 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 intemet.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.
Page 4 of 6
Permit NC0025691
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 21,2020,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:
http://www2.epa.gov/compliance/final-national-pollutant-discharge-elimination-system-npdes-
electronicreporting-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:
https://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B.Li!.)(b)and supersedes Section B.(11.)(d)1
