The Division has reviewed your request to renew the subject permit. Please review this draft carefully
to ensure your thorough understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
➢ Language has been added in Section A. (1) and as Section A. (2) to require electronic submission
of effluent data. Federal regulations require electronic submittal of all discharge monitoring
reports (DMRs).
➢ Regulatory citations have been added to the permit.
➢ Outfall map has been updated.
Language has been updated on the Supplement to Permit Cover Sheet per the current water
treatment plant strategy.
➢ Parameter codes have been added to Section A. (1).
➢ Monitoring for turbidity has been changed to 2/Month per the current water treatment plant
strategy in Section A. (1).
➢ The unit of measure has been changed to gg/L for Total Fluoride in Section A. (1).
➢ Monitoring for Ttoal Iron has been removed as there is no longer a water quality standard.
➢ The Total Residual Chlorine footnote has been updated in Section A. (1).

1. The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR
application system [see A. (2)].
2. Flow estimate shall be based on daily discharge activities to outfall. Duration and flowrate of discharge
should be noted in log book and supported flows reported on DMR.
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.
4 TN = TKN + NO3-N + NO2-N; where TN is Total Nitrogen, TKN is Total Kjeldahl Nitrogen, and NO3-N
+ NO2-N are Nitrate and Nitrite Nitrogen respectively.
5. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent
metals (cadmium, copper, lead, nickel, silver, and zinc).
6. The Permittee shall sample instream hardness, upstream of the facility's discharge The sample shall be
representative of the hardness in the receiving stream. If the Permittee is a member of the Monitoring
Coalition Program, sampling for instream hardness may be waived as long as the Monitoring coalition
agrees to sample hardness at the nearest upstream location, at a minimum frequency of quarterly, and the
Permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being
monitored by the Coalition is representative of the receiving stream for this discharge. The Permittee is
responsible for submitting instream hardness test results with its permit renewal application package. If
Coalition membership is cancelled or the Coalition terminates instream hardness sampling at the
approved station, the Permittee will immediately notify the Division and resume sampling for instream
hardness, upstream of its discharge.

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. 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.
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.
Page 4 of 6

Permit NC0086918
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: 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.ne.gov/about/divisions/water-resources/edmr
