Dear Mr. Steinert:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly,we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007
(or as subsequently amended).
The following changes were made to the draft permit sent to you on February 25, 2022:
• Total Cadmium: Quarterly monitoring requirement was removed [See A. (1.)].
• Chronic Toxicity: Mailing address for DWR Form AT-3 was updated [See A. (2.)].
• Dissolved Oxygen: Correction of sampling type to specify grab samples [See A. (1.)]
• Correction was made to the treatment component list to remove the dual activated carbon
adsorption units with pH adjustment which were taken out of service in 2021.
• Correction made to footnotes 4 and 5 [See A. (1.)].
The final permit maintains the following significant changes identified in the letter sent on
February 25,2022:
• Total Selenium: Quarterly monitoring for total selenium has been removed from the permit
based on no reasonable potential to exceed water quality standards [See A. (1)].
• Ammonia-nitrogen: Per the results of instream waste concentration (IWC)-based calculations
for ammonia-nitrogen, seasonal ammonia nitrogen limits have been added to reflect
appropriate, separate limits for summer and winter months [See A. (1.)].

DocuSign Envelope ID:0185CAF6-8409-4E73-9F62-6AD7BFE3763B
• Dissolved Oxygen: Daily average effluent limit of not less than 5.0 mg/L for dissolved oxygen
has been added to the permit in accordance with state water quality standards for class C,non-
trout waters 15A NCAC 02B .0211(6) [See A. (1.)].
• Chronic Toxicity: Some of the wording has updated in Special Condition A. (2.), Chronic
Toxicity Permit Limit, please review each paragraph carefully.
• A notation was made concerning the Electronic Reporting Rule—NPDES Electronic Reporting
Rule—Phase 2 Extension. EPA extended the Phase 2 deadline to December 21, 2025. Federal
regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The requirement to continue reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR) internet
application has been added to your NPDES permit [See Special Condition A. (3.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements [
See A. (1.)].
• Regulatory citations have been added to the permit.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-
6714). Unless such demand is made, this decision shall be final and binding.
The NPDES standard conditions (Parts II, III, and IV) are the same as in your current permit
except that agency and division names have been updated. The latest version is available at
https://bit.ly/3k5NFaL and can be viewed online or downloaded as a PDF file.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect
the legal requirements to obtain other permits which may be required by the Division of Water
Resources or any other Federal, State, or Local governmental regulations.
If you have questions concerning this draft permit, please call me at [phone] or by
email at [e-mail].

Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR
application system [see A. (4)].
2. Total residual chlorine shall be monitored only if chlorine is added to the treatment process. 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.
3. 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.
4 Metal sampling shall be performed in conjunction with total hardness effluent sampling
5. Chronic Toxicity(Ceriodaphnia)limit at 48%with testing in February,May,August,and November[see
A. (2)].
There shall be no discharge of floating solids or visible foam in other than trace amounts.
A. (2) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 48%.
The permit holder shall perform at a minimum, quarterly 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 2010)or
subsequent versions. The tests will be performed during the months of February,May,August, and November.
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.
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:

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 the cited document, such as minimum control organism
survival,minimum control organism reproduction, and appropriate environmental controls, shall constitute an
invalid test and will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.
