significant mortality to Ceriodaphnia dubia at an effluent concentration of 44 % at the
effluent limit of 0.6 MGD.
The permit holder shall perform at a minimum,quarte rlu monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised- December 20 10) or subsequent versions. The tests will be
performed during the months of January, April, July, and October. These months
signify the first month of each three-month toxicity testing quarter assigned to the facility.
Effluent sampling for this testing must be obtained during representative effluent discharge
and shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
Page 7 of 11

Permit NC0040011
If the test procedure performed as the first test of any single quarter results in a
failure or ChV below the permit limit, then multiple -concentration testing shall be
performed at a minimum, in each of the two following months as described in "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -December
2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the
Effluent Discharge Monitoring Form (MR -1) for the months in which tests were performed,
using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value.
Additionally, DWR Form AT -3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/ physical
measurements and all concentration/ response data, and be certified by laboratory
supervisor and ORC or approved designate signature. Total residual chlorine of the effluent
toxicity sample must be measured and reported if chlorine is employed for disinfection of the
waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top of the
aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number,
county, and the month/year of the report with the notation of "No Flow" in the comment
area of the form. The report shall be submitted to the Water Sciences Section at the address
cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Assessment of toxicity compliance is
based on the toxicity testing quarter, which is the three month time interval that begins on
the first day of the month in which toxicity testing is required by this permit and continues
until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North
Carolina Division of Water Resources indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or
limits.
NOTE: Failure to achieve test conditions as specified in
minimum control organism survival, minimum control
appropriate environmental controls, shall constitute an
immediate follow-up testing to be completed no later th
following the month of the initial monitoring.

A. (5) ELECTRONIC REPORTING OF 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 Requirements (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) 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.
Starting on December 21, 2020, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
Page 9 of 11

Permit NCO040011
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Deports.
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:
httID: / / www2.epa.9ovj compliance' final-national-i:)ollutant-discharge-elimination
ss! stem-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:
