Subject: Final NPDES Permit Renewal
Permit NC0026051
Triangle WWTP
Durham County
Grade IV Biological WPCS
SIC Code 4952
Dear Ms. Brixey:
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 second draft permit sent to you on May 12,2022:
• A footnote was added to the instream monitoring section [A. (8.)] to provide the Permittee a
provisionary waiver for membership in a monitoring coalition.
• Several numbering typos were corrected.
• Based on detection of PFAS chemicals(including PFOA and PFOS) and the discharge into a WS-
IV water,PFAS monitoring was increased to quarterly based on recently updated draft EPA Health
Advisories.
Attached is a listing of comments received and Division responses in the form of a Fact Sheet Addendum.
This final permit maintains the following significant changes identified in the letter sent on May 12,
2022:
• The system component list on the Supplement to Cover Sheet was revised based on communication
with facility staff.
• Based on your request and NPDES guidance regarding the reduction of monitoring frequencies in
NPDES permits for exceptionally performing facilities, monitoring requirements for BOD5, Total
Suspended Solids,Ammonia-Nitrogen and Fecal Coliform will continue reduced at twice per week
[See A. (1.)].
• Based on the reasonable potential analysis (RPA) showing no reasonable potential to violate state
water quality standards, the monitoring requirement for Chloroform, Bromodichloromethane,
Dibromochloromethane, Total Copper and Total Zinc were removed from thepermit [see A. (1.) .

• Based on the RPA showing no reasonable potential to violate state water quality standards,but the
maximum predicted value is> 50%of the allowable concentration, limits for Total Fluoride were
removed from the permit and monitoring was reduced to quarterly [see A. (1.)].
• Based on the RPA showing reasonable potential to violate state water quality standards with a
limited dataset (n < 8 samples) and two (2) values above the allowable effluent concentration,
quarterly monitoring for Bis(2-ethylhexyl)phthalate and Nitrate-Nitrogen(NO3-N)were added to
the permit [see A. (1.)].
• Based on Mercury TMDL evaluation showing no individual results exceeded the TBEL of 47 ng/L
and no annual average exceeded the WQBEL of 12.0 ng/L,total mercury limits were removed from
the permit.
• Based on Mercury TMDL evaluation showing mercury detectable values reported at levels > 1
ng/L and since the permitted flow is greater than 2 MGD, a Mercury Minimization Plan special
condition was added to the permit [see A. (1.)and A(11.)].
• The Division is implementing dissolved metals standards in all permits, per the 2016 revisions to
State water quality standards.As such, the NPDES Permitting Unit will need site-specific effluent
hardness data for each facility monitoring these metals in order to calculate permit limitations.
Effluent hardness was added to the permit at a quarterly monitoring frequency [See A. (1.)].
• Based on the Jordan Lake nutrient strategy (15A NCAC 02B .0270), nutrient allocations are set
among permitted dischargers; nutrient load allocations can be raised if a permitted source connects
to another permitted source, thereby receiving that other source's allocation and thus raising its
limits. Since the Triangle WWTP is receiving additional load from non-permitted sources, the
additional load must fit within the facility's allocations to meet compliance. The allocated nutrient
loads are maintained in the permit[see A. (6.)].
• Based on minimum monitoring requirements for domestic wastewater facilities (15A NCAC 02B
.0508), instream (upstream and downstream) monitoring for Dissolved Oxygen, Temperature,
Fecal Coliform and Conductivity are maintained in the permit,but reduced to a monthly frequency
[See A. (2.)].
• Based on the facility treating industrial wastewater,conductivity effluent monitoring was added to
the permit [See A. (1.)].
• Based on concerns over loss of instream monitoring efforts in tracking the progress of the Jordan
Lake nutrient strategy (15A NCAC 02B .0262), instream monitoring for Total Phosphorus (TP),
Orthophosphate (PO4), Total Kjeldahl Nitrogen (TKN), Nitrate + Nitrite (NO3+NO2), and
Ammonia-N(NH3-N)were added to the permit at monthly frequencies [See A. (2.)].
• Based on detections of the emerging contaminant 1,4-Dioxane in the waste stream at levels < 10
µg/L from limited data (< 12 samples) in July-September 2019, monthly monitoring for 1,4-
Dioxane was added to the permit.
• A permit reopener special condition was added to modify 1,4-Dioxane monitoring,treatment and/or
compliance [see A. (11.)].
• A special condition to monitor effluent PFAS chemicals was added to the permit, to be effective
six (6) months after EPA has a final wastewater method in 40 CFR136 method published in the
Federal Register.
• Some of the wording has changed in Special Condition A. (3.), Chronic Toxicity Permit Limit,
please review each paragraph carefully.
• Special Condition A. (4.) was modified to include the specific three years in which the Effluent
Pollutant Scan shall be performed (2024, 2025, and 2026). In addition, at the end of the Special
Condition, 2nd species Toxicity Testing Requirements for municipal permit renewals per Federal
Regulations [40 CFR 122.21(j)(5)] was added.
• 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 was
added to the permit[See Special Condition A. (13.)].

in relation to the Outfall.
Pretreatment updates in response to NPDES permit renewal:
• On February 28, 2023, 180 days after the effective date of this NPDES permit renewal, Durham
County is required to submit to the Division a written technical evaluation of the need to revise
local limits (i.e., an updated IWS/HWA-AT/L-STMP, or documentation of why is not needed).
This action may include revising, updating, or adding to the list of SIUs regardless of timeframe.
o Submit the updated Long-Term Monitoring Plan(LTMP)
• Review pollutants of concern(POCs)and update the LTMP to reflect pollutants in
industrial user permits(IUPs)and sludge management permit.
• The specific PFAS parameters are to be determined upon EPA publishing a final
wastewater method in 40 CFR 136 in the Federal Register.
o As part of the local limits assessment, please submit the updated Headworks Analysis
(HWA).
If any parts,measurement frequencies or sampling requirements contained in this permit are unacceptable,
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

Triangle WWTP Fact Sheet Addendum NC0026051
The Division received comments to the Triangle WWTP draft NPDES Permit from Durham County on
June 16,2022,and provides the following responses:
Comment: The County requests "Bis(2-ethylhexyl) phthalate be removed from the permit or at least be
limited to quarterly monitoring for two years so that eight samples can be collected and then NCDWR can
evaluate whether there is a reasonable potential. Bis(2-ethylhexyl) phthalate hits are typically due to
sampler and/or lab contamination. Out of three results, the last two were less than detect which could
lead one to believe the first was a contaminated sample."
Response: Request considered;The reported Bis(2-ethylhexyl) phthalate concentrations are valid results
certified by the laboratory and have been incorporated into the Reasonable Potential Analysis. As such,
the monitoring requirements have been maintained.
Comment:The County requests"1,4-Dioxane be removed from the permit as the three values used were
influent results, but NCDWR used these results as if they were effluent results to suggest reasonable
t
potential to exceed a water quality standard that has not been adopted. NCDWR also used one half on
the detection limit for the values that were less than when this method should only be used for
pretreatment determinations. Per the DMR guidelines, less than values are considered zero which would
have put the average under the allowable effluent concentration."
Response: 1,4-Dioxane is completely miscible in water and resistant to degradation under conventional
treatment. As such, detectible amounts in the influent indicate presence in the effluent. In evaluation,
RPA uses half of the detection level for results below detection; the guidance referenced in the request
pertains to calculating averages for DMR submittal, not RPA. Further, one of the non-detects is< 2 ug/L,
which is above the Division's recommended level of 1 ug/L. 15A NCAC 2B .0505 (e) (4) requires that all
test procedures must produce detection and reporting levels that are below the permit discharge
requirements and all data generated must be reported to the approved detection level or lower reporting
level of the procedure. If no approved methods are capable of achieving a detection level below the
permit discharge requirement (or allowable discharge concentration) the method with the lowest
detection level must be used.The County should use sufficiently sensitive test methods for all pollutants,
including when performing Effluent Pollutant Scans. 1,4-Dioxane monitoring has been maintained in the
permit.
Comment:The County requests"PFAS only required to be monitored annually. From the last four analyses
completed, Triangle Wastewater Treatment Plant (TWWTP) was below the allowable effluent
concentration of 145.27 ng/L. Durham County staff has surveyed all industrial users,Significant and Local,
and have notified them that PFAS is not allowed to be discharged. Page 15 of the Fact Sheet states that
more results are needed for evaluation, and it is believed that annual sampling will provide that
information. Also, there is no information to suggest reasonable potential to exceed a water quality
standard that has not been adopted."
Response:EPA has revised the draft Health Advisories for PFAS parameters PFOA and PFOS to levels below
detection. Based on the detection of these and other PFAS parameters, monitoring for PFAS has been
increased from 2/year to quarterly. To clarify, since an EPA method for sampling and analyzing PFAS in
wastewater is not published in the Federal Register,the PFAS sampling requirement in the Permit includes
a compliance schedule which delays the effective date of this requirement until the first full calendar

DocuSign Envelope ID:72D4F5D6-EB4A-4F61-9CDA-5AC7B40D777A
Triangle WWTP Fact Sheet Addendum NC0026051
quarter beginning 6 months after EPA has a final wastewater method in 40 CFR 136 published in the
Federal Register.This date may be extended upon request and if there are no NC-certified labs.
Comment: "Durham County is requesting that the in-stream monitoring requirements A.(2.) be revised to
remove the nutrient monitoring. Currently, NCDWR has a Memorandum of Agreement with the Upper
Cape Fear River Basin Association which samples downstream of the TWWTP, Station B367000 and
upstream of the TWWTP, Station B3300000 for nutrients.
Durham County believes this is redundant sampling and is an inefficient use of resources. Durham County
may contest any stream sampling beyond the minimum required by 15A NCAC 02B .0500. Please note
Durham County has in-house certifications for the tests required by 15A NCAC 02B .0500.The additional
tests required in the draft permit requires the use of outside labs and considerable expense. Please
recognize that Durham County voluntary submitted to the early application of the Jordan Lake nutrient
limits, and as such believes it is most appropriate to use ratepayer's remittances for the treatment of
wastewater and not for redundant stream monitoring.
Furthermore, the In-stream Waste Concentration (IWC) is 100%, which caps our toxicity sampling
requirements at 90%, and the 7010 flow is 0 cubic feet per second (cfs) for Northeast Creek making the
creek makeup mainly our effluent discharge. Durham County is already required to monitor nutrients on
the effluent.Again,this is redundant monitoring and inefficient use of resources."
Response: The footnote to the instream monitoring table [A. (8.)] has been revised to include a
provisionary waiver for membership to a monitoring coalition.To reiterate, based on concerns over loss
of instream monitoring efforts in tracking the progress of the Jordan Lake nutrient strategy (15A NCAC
02B .0262)as a direct result of the removal of instream nutrient monitoring in the 2011 permit, instream
monitoring for Total Phosphorus (TP), Orthophosphate (PO4), Total Kjeldahl Nitrogen (TKN), Nitrate +
Nitrite (NO3+NO2), and Ammonia-N (NH3-N) was reinstated in this permit. The monitoring frequencies
were adjusted to monthly to be consistent with those taken by monitoring coalitions so that if the
Permittee chooses to join a monitoring coalition, instream monitoring may be waived with Division
notification.
Comment: "On page 7, the next to last paragraph states, "If the permittee monitors any pollutant more
frequently than required by this permit,the results of such monitoring shall be included in the calculation
& reporting of the data submitted on the DMR and all AT Form submitted." This should be modified to
state "monitors any effluent pollutants more frequently than required" per 15A NCAC 02B .0506 as there
is no regulation requiring reporting for additional influent or other location data not specified in the
NPDES permit."
Response: Comment received. As this language is standard language consistently applied to permits the
language has been maintained.
Comment: "The following typos need to be addressed" [a list of numbering typos is given].
Response:All typos have been corrected.

A.(3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) [15A NCAC 02B.0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90%.
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
Chronic Value (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 electronically using
the Division's eDMR system 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:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Or, results can be sent to the email,ATForms.ATB@a,ncdenr.gov.
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
