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

NC DENR / 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.
Starting on December 21, 2020, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
® Sewer Overflow/Bypass Event Reports;
o Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.

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.
Page 5 of 7
Permit NCO021849
Class WW-3
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

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

83 Process description Sheet 2
The treatment facility is a 0.700 MGD rated activated sludge process with tertiary treatment. The
facility has been in operation since 2008. This facility replaced a 0.300 MGD secondary treatment facility.
Preliminary Treatment (Numbers 1-4)
The wastewater enters the facility via two force mains (one for the Town of Hertford and one
for the Town of Winfall). It first passes through mechanical screens with trash washer. It then
passes through a parshall flume with flow measurement. It next passes through grit removal
consisting of continuously rotating paddle, grit pump and cyclone water separator with
conveyor. The trash and grit are removed from the site for landfill disposal. It then enters the
influent pump station, consisting of three pumps, that sends it to the oxidation ditches.
Secondary Treatment (Numbers 5-7)
The secondary system consists of three mechanically aerated oxidation ditches, splitter box and
two secondary clarifiers.
Tertiary Treatment/Disinfection/Effluent Disposal (Numbers 8-12)
The tertiary treatment, after clarification, consists of two parallel disk filters, chlorine injectors
and pontact tanks. The disk filters are rated for 10 MGD each, and each contact tank will
provide 30 minutes of contact time at that rate. After disinfection, there is the effluent pump
station, consisting of three pumps, that sends the treated water either to the Perquimans River,
or to the spray field storage tank. After the pump station is sulfur dioxide injection, for de -
chlorination. The choice of discharge is based on several conditions. Spray field operation is
handled under permit WQQ021289.
Sludge Handling (Numbers 13-19)
The Settled solids from the clarifiers either returns to the influent pump station as Return
Activated Sludge (RAS) or tp the aerobic digester ps Waste Activated Sludge (WAS). The choice
is made at the RAS/WAS splitter box. Waste sludge is sent to the aerobic digester, where it is
held for at least 30 days under aeration, supernatant is withdrawn and returned to the plant,
and then sent to the sludge storage tank to be held until final disposition The sludge can either
be sent to the drying beds to be dewatered and disposed of, or sent to the truck loading station
and be hauled to approved fields to be disposed of as a liquid. Sludge operations are handled
under permit WQ0020239.
