weekly during the months of June,July,August and September and twice per month during the rest of the year.
3. The monthly average effluent BODS and Total Suspended Solids concentrations shall not exceed 15%of the respective
influent value(85%removal).
4. The quarterly average for Total Phosphorus shall be the average of composite samples collected 2/month during each
calendar quarter(January-March,April-June,July-September,October-December).
5. For a given wastewater sample, TN = TKN+NO2-N +NO3-N, where TN is Total Nitrogen, TKN is Total Kjeldahl
Nitrogen,and NO2-N and NO3-N are Nitrite and Nitrate Nitrogen,respectively.
6. Total Nitrogen Load is the mass load of Total Nitrogen discharged in a given period of time. See special condition A.
(2.),Calculation of TN Loads.
7. A statewide Total Maximum Daily Load(TMDL)for Mercury has been approved by the US EPA. Municipal wastewater
discharges with NPDES permits must monitor or limit Mercury to comply with the TMDL. The permittee shall collect&
analyze at least one sample of Total Mercury during this permit cycle.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN
TRACE AMOUNTS.
A. (2) CALCULATION OF TOTAL NITROGEN LOADS
[15A NCAC 02B .0500 et seq.]
The permittee shall calculate monthly and annual TNkas follows:
i. Monthly TN Load (pounds/month) =TN x T F 8.34
where:
TN = the average TN concen ration(mg/L) of the samples collected during
the month.---- 7
TMF = the Total�Mo y Flow of wastewater discharged during the month
(MG/onth
8.34 = converssiYon factor, from(mg/L x MG) to pounds
ii. Annual TN Lo (pounds/year) = Sum of the 12 Monthly TN Loads for the calendar year
The permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in the appropriate
discharge monitoring report for each month and shall report each year's results (pounds/year) with the
December report for that year.
A. (3) TOTAL NITROGEN ALLOCATIONS
[G.S. 143-215.1(b)]
The following table lists the Total Nitrogen(TN) allocation(s) assigned to, acquired by, or transferred to
the permittee in accordance with the Neuse River nutrient management rule (T15A NCAC 02B .0234)
and the status of each as of permit issuance. For compliance purposes, this table does not supercede any
TN limit(s) established elsewhere in this permit or in the NPDES permit of a compliance association of
which the permittee is a co-permittee member.

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:

Grade II Biological WPCS [15A NCAC 08G.0302]
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.
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.

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 submissi J..‹Ihepermittee should use the EPA's website resources to identify the
initial recipient for the electronicysubmiron.
Initial recipient of elect P ES information from NPDES-regulated facilities p / �N gu means the entity
(EPA or the state- <thorized/by EPA to implement the NPDES program)that is the designated entity
for receiving electrorr'DES 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-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

Permit NC0061492
Grade II Biological WPCS[15A NCAC 08G.0302]
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
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)

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 theI R 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:
t fiLL7�-�,j
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

am aware that there are significant penalties for submitting false information, including the
possibility of fines and imprisonment for knowing violations."
5. Records Retention [Supplements Section D. (6.)1
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
