the other months of the year. As a participant in the Yadkin -Pee Dee River Basin Association, the instream
monitoring requirements for dissolved oxygen, temperature, fecal coliform and conductivity are waived.
Should your membership in the association be terminated, you shall notify the Division and begin instream
sampling immediately.
3. The monthly average effluent BOD5 and Total Suspended Solids concentrations shall not exceed 15% of the
respective influent value (85% removal).
4. Monitoring only if effluent is chlorinated. 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 lag/L.
5. 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.
6. A 5-year schedule of compliance has been added to the permit [See A. (5) Schedule of Compliance for total
copper].
7. Effluent Total Hardness sampling shall be conducted in conjunction with effluent metals for the pretreatment
program (Cadmium, copper, lead, nickel, silver, and zinc).
8. 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 a 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.
9. Chronic Toxicity (Ceriodaphnia) limit at 50% with testing in January, April, July and October [see A. (2)].
10. The permittee shall perform three effluent pollutant scans during the term of this permit [See A. (3)].
[Summer] = April 1- October 31 [Winter] = November 1- March 31
There shall be no discharge of floating solids or visible foam in other than trace amounts.

submit DMRs electronically using the internet. The eDMR system may be accessed at:
https://deq.nc.gov/about/divisions/water-resources/edmr.
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, 2025, 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 s://www.federalregister.gov/documents/2015/ 10/22/2015 -24954/national-pollutant-discharge-elimination-
system-npde s-electronic-reporting-rule .
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
