Subject: Draft NPDES Permit Renewal
Permit NCO020664
Town of Spindale W WTP
Rutherford County
Grade IV Biological WPCS
SIC Code 4952
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BOD5, NH3-N,
Total Suspended Solids and Enterococci have been reduced to twice per week [See A.(1.)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards, total copper limits have been maintained in the permit. However,
as total copper standards are dependent on stream and effluent hardness, the limits have been
revised to reflect updated hardness information. Please review the change carefully [See
A.(1.)].
Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards, total cyanide limits and monthly monitoring have been added to
the permit [See A.(1.)].
Based on the reasonable potential analysis (RPA) predicting a maximum effluent chloride
concentration that is greater than half of the allowable discharge concentration based on state
water quality standards, quarterly monitoring for chloride has been added to the permit [See
A.(1.)].
• Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards, the limits and monitoring requirement for total silver has
been removed from the permit [See A.(1)].
To address noted issues at the facility pertaining to the largest clarifier, Special Condition
A.(5.) Wastewater Management Plan has been added to the permit.

��vy,a� 919.707.9000

To assess industrial contributions of PFAS chemicals to the Spindale W WTP and assess
levels in the facility effluent, Special Condition A.(6.) has been added to the permit.
Some of the wording has changed in Special Condition A. (2.), Chronic Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A.(3.) has been modified to include the specific three years in which
the Effluent Pollutant Scan shall be performed (2026, 2027, and 2028).
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.
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included
in this draft document (cover, map, and Part I). The conditions 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.
Concurrent with this notification the Division is publishing a notice in a newspaper having
circulation in the general Cleveland County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following: NCDEQ/DWR, NPDES
Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 no later than 30 days after
receipt of this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments
and take appropriate action prior to issuing a final permit. If you have questions concerning this
draft permit, please call me at [phone] or by email at [e-mail].

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 19%.
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
March, June, September, and December. 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 NPDES11 jpermitted final effluent discharge
below all treatment processes. ./ r`
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 beperformed at a minimum, in each of the
two following months as described in "North Carolina Phase H Chionic.Whole Effluent Toxicity Test
Procedure" (Revised -December 2010, or subsequent versions).
All toxicity testing results required as part of thisfpermit condition will be entered electronically using the
Division's eDMR system for the months in which tests were performed, using the.par meter code TGP3B

Test data shall be complete, accurate; include all supporting chemical/physical measurements and all
concentratidrrlresponse data, arid,be certified=by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine %of the effluent'toxicity�Ample must be measured and reported if
chlorine js employed for disinfection of the waste stream.
Should there be no discharge of flow frdm the facility during a month in which toxicity monitoring is
required, thepermittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating thefacility name,�peimit number, pipe number, county, and the month/year of the report
with the notation of."No Flow" in the kcomment 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.

Method 1633 in 40 CFR Part 136, data shall be reported ih,the monthly eDMRs.
Please note that specific consideratibr s�annd-protocols are required to avoid cross -contamination and
minimize sample bias for PFAS. A current listing of laboratories accredited by the Perry Johnson
Laboratory Accreditation, --Inc. (PJLA), 'ANSI National-Accredittation Board (ANAB), or the
American Association for Laboratory Accreditation;(A2LA) to,perform EPA Method 1633 can be
found by contacting the individual associations., -Please note that different labs are accredited for
different matrices.'``• `~\ t i �`

have to be in North,Carolina.?
(c.) Pretreatment program activities:
(i.) HAS Monitoring,Ap'plicability: Industry categories known or suspected to discharge PFAS
from the EPA PFAS Strategic Roadmap include: organic chemicals, plastics & synthetic fibers
(OCPSF); metal finishing; electroplating; electric and electronic components; landfills; pulp,
paper & paperboard; leather tanning & finishing; plastics molding & forming; textile mills;
paint formulating, and airports. This is not an exhaustive list and additional industries may also
discharge PFAS. For example, Centralized Waste Treatment (CWT) facilities may receive
wastes from the aforementioned industries and should be considered for monitoring. There may
also be categories of dischargers that do not meet the applicability criteria of any existing
Effluent Limitation Guidelines (ELG); for instance, remediation sites, chemical manufacturing
not covered by OCPSF, and military bases. 1

Permit NCO020664
' ELG categories of airport deicing, landfills, textile mills, and plastics molding and forming do not
have categorical pretreatment standards, and therefore small -volume indirect dischargers in those
categories would not ordinarily be considered Significant Industrial Users (SIUs) and may not be
captured on an existing IU inventory. IUs under the Paint Formulating category are only subject to
Pretreatment Standards for New Sources (PSNS), and existing sources may need to be inventoried.
(ii.) The Permittee shall identify and locate each Significant Industrial User (SIU) in the approved
pretreatment program in industry categories expected or suspected of PFAS discharges to the
Spindale WWTP; and begin sampling of and modify Industrial User Permits (IUPs) for each
SIU identified as suspected of PFAS discharges to the Spindale WWTP to ensure sampling
begins within six months of the permit effective date, by Month xx, 2024.
(iii.) Update Industrial Waste Survey (IWS) Inventory: POTWs must identify and locate all possible
indirect dischargers that might be subject to the pretreatment program and identify the character
and volume of pollutants contributed to the POTW by`the indirect dischargers (see 40 CFR
403.8(f)(2)). As EPA regulations require, this information shall be provided to the Division (see
40 CFR 122.440) and 40 CFR 403.8(f)(6)).ds part of the 2025.Pretreatment Annual Report
(PAR). The IWS inventory shall be revised, as necessary, to include all indirect dischargers in
industry categories expected or suspected of PFAS discharges:r.,(see 15A NCAC 02H
.0906(b)(2))• ti �•< <
t-
(iv.) The Permittee shall begin sampling of and/or issue IUPs for each indirect discharger identified
as suspected of PFAS discharges to the Spindale WWTP4o ensure sampling begins within six
months of completion of the IWS.
(v.) The Division has determined,that,all SIUs and indireet,dischargers identified above analyze
their discharge for PFAS at the'same-quarterly sampling frequency and with the same
analytical method -.to ensure protection 'of human health and the environment due to the
potential health hazards,associatedtwith PFAS. Collection and evaluation of this information
will also 'assist the Department inideveloping sound,policies with respect to PFAS in the
(vi.) The Peimittee shall,ensure that IUPs withinNthe Spindale WWTP service area are modified or
,reissued; new IUPs are issued, annd,other Pretreatment Program mechanisms are completed to
In the absence oflocal''limits, and based upon data as they become available, POTWs shall
encourage Best Management Practices (BMPs), pollution prevention, product substitution, and
good housekeeping,pr'a ices tonake meaningful reductions in PFAS introduced to POTWs.
Such'BMPs could be like those -included in the EPA Office of Water, December 5, 2022,
"Addressing PFAS Discharges in NPDES Permits and Through the Pretreatment Program and
Monitoring Programs:" A3. "Best Management Practices (BMPs) for discharges of PFAS,
including product substitution, reduction, or elimination of PFAS, as detected by draft method
1633".
(viii.) A summary of all actions taken by the Permittee and their industries and monitoring conducted
by each indirect discharger identified as part of this Special Condition shall be provided as part
of the PAR (see I SA NCAC 02H .0908(b)).
