Subject: 3rd Draft NPDES Permit Renewal
Permit NC0020664
Spindale WWTP
Rutherford County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Webber:
Enclosed with this letter is a copy of the third draft NPDES permit renewal for your facility. This third
draft is being sent for review and public comment in light of the proposed compliance schedule extended
from three to four years. Please review this draft carefully to ensure a thorough understanding of the
requirements and conditions it contains.
The following changes were made to the second draft permit sent to you on January 29, 2020:
• The BOD parameter in Section A. (1.) was corrected to year-round by removing"Summer (Apr
1 —Oct 31)".
• Wording in Special Condition A. (3.) — Effluent Pollutant Scan, have been inserted to allow for
e-mail submittal of 2nd species toxicity test results.
• As justified by the Permittee, the Compliance Schedule for Total Copper and Total Silver
[Special Condition A. (4.)] has been extended from three to four years, and wording has been
modified to include annual summary submittals in the first two years and submittal of a
Corrective Action Plan in the third year. Please review it carefully.
A detailed response to the comments received from the Town of Spindale on February 17, 2020 and
subsequent communication can be found in the 3rd Draft Fact Sheet Addendum attached to this letter.
As explained before, the following changes were made to the original and second draft permits as
follows:
• To provide an opportunity for the Town to sample and assess sources of Total Copper and Total
Silver in order to come into compliance with the limits in Section A. (1.), a 3-year schedule of
compliance has been added to the permit.

• The upstream sampling location was modified for a more accurate description [See Section A.
(1.), Footnote 2.].
• Wording in Special Condition A. (2.) Chronic Toxicity Pass/Fail Monitoring, and A. (3.) —
Effluent Pollutant Scan,have been updated to allow for electronic submittal. Please review each
special condition carefully.
• The Supplement to Permit Cover Sheet has been modified to reflect the corrections made to the
system refurbishment Authorization to Construct(AtC)Permit No. 020664A02 on May 6,2016.
• Ammonia-nitrogen limits have been changed to reflect appropriate, separate limits for summer
and winter months [See A. (1.)].
• Based on the reasonable potential analysis(RPA)showing no reasonable potential to violate state
water quality standards, the monitoring requirement for selenium, zinc and chlorides have been
removed from the permit [See A. (1.)].
• Based on the RPA showing reasonable potential to violate state water quality standards, total
copper and total silver limits have been added to the permit and the quarterly monitoring
requirement has been changed to monthly monitoring[See A. (1.)].
• Based on Mercury TMDL evaluation showing mercury values reported at levels > 1 ng/L and
since the permitted flow is greater than 2 MGD, wording in Special Condition A. (5.) Mercury
Minimization Plan has been modified toward its maintenance.
• Based on DWR Instream Fecal Coliform Monitoring Guidance, since the facility discharges to
waters that are neither impaired for fecal coliform nor Class B waters, fecal coliform has been
removed from instream monitoring requirements [See A. (1.)].
• The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA
subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC
Division of Water Resources NPDES Permitting Unit is required to implement the new dissolved
metal standards in all permits public-noticed after April 6, 2016. The new standards for most
metals include acute standards. Further,the freshwater standards for several metals are expressed
as the dissolved form of the metals, and seven metals have hardness-dependent equations. As a
result, the NPDES Permitting Unit will need site-specific effluent hardness data and instream
hardness data, upstream of the discharge, for each facility monitoring these metals in order to
calculate permit limitations. Effluent hardness and instream hardness sampling, upstream of the
discharge,have been added to the permit at a monitoring frequency of quarterly[See A. (1.)].
• The Town of Spindale reported Total Silver at less than detection, with detection levels < 2.5
µg/L in their DMR results and<5.0 µg/L in the Effluent Pollutant Scans. The Town's allowable
discharge concentrations are 0.3 µg/L (chronic) and 1.7 µg/L (acute) for Total Silver. DWR's
laboratory identifies the target Practical Quantification Limits(PQLs)for Total Silver as 1.0 µg/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
Town should use sufficiently sensitive test methods for all pollutants,including when performing
Effluent Pollutant Scans.
• Special Condition A. (3.) has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed(2021, 2022, and 2023). In addition, at the end of the
Page 2 of 3

Special Condition,2nd species Toxicity Testing Requirements for municipal permit renewals per
Federal Regulations [40 CFR 122.21(j)(5)] have been 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 has
been added to your NPDES permit [See A. (6.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements[See
A. (1.)].
• Regulatory citations have been added to the permit.
• The permit map has been modified to show instream monitoring locations and corrected outfall
coordinates.
Please note that the receiving stream is listed as impaired for Fish Community on the 2018 North
Carolina 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division,
and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits
and stream impairment can be attributed to your facility, then mitigative measures may be required.
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/2BZ4xxx 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 Rutherford 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(919) 707-3611 or by email at [e-mail].

3rd Draft Fact Sheet Addendum
The Permittee provided comments for the Spindale WWTP (NC0020664) 2"d draft permit, public noticed
on January 29, 2020. Comments by Scott Webber,Town of Spindale (Permittee)with DWR responses
are as follows:
Comment: "In section Al,the BOD parameter includes the dates(Apr 1—Oct 31)3.The superscript
references footnote 3 on the following page and indicates 85% BOD removal. Does the BOD limit only
apply between those dates or does the 85%removal only apply between those dates? Please confirm
the intent of the dates in the BOD parameter."
Response:The dates were removed as they were inserted in error.The revised draft permit does not
have dates associated with the BOD limits, indicating that these are year-round limits subject to the 85%
removal requirement.
Comment: "The first page of the permit indicate an effective date in the 2019 year, we are assuming the
effective date will be in the 2020 year. Please confirm."
Response:The effective date will be in 2020.
Comment: "Section A3 indicates the pollutant scan should 'determine whether parameters are present
in concentrations greater than applicable standards and criteria'. Please provide a reference to
applicable standards and criteria?"
Response: Applicable standards and criteria include those in 15A NCAC 02B .0211—Fresh Surface Water
Quality Standards for Class C Waters.A link to the NC water quality standards table
(https://deq.nc.gov/documents/nc-stdstable-06102019) was sent to the Permittee and ORC via e-mail
on March 19, 2020.
Comment: "The proposed monthly average silver limit is 0.3 µg/L.The minimum reporting limit of the
testing procedure available is 0.5 µg/L. Please confirm that a non-detect or'<0.5 µg/L' will meet the
proposed limit.
Response: Non-detect results of the lower reporting limit of the procedure will indicate compliance for a
limit that is below detection.This was communicated to the Permittee and ORC via teleconference on
March 16, 2020.
Comment: "In section A3,the effluent pollutant scan can be submitted electronically or mailed, can the
second species toxicity test also be submitted to the Aquatic Toxicity Branch electronically?"
Response: 2nd sp. toxicity reports can be submitted electronically to [e-mail] PPA
Special Condition was modified to allow for 2"d sp. toxicity tests to be electronically submitted. Section
A.3 was modified to include electronic submittal.
Comment: "In section A6, it states that the monitoring reports should be submitted through eDMR and
printed and mailed to DWR. Currently the monitoring reports are submitted through eDMR and
submitted via email to DWR. We would ask that section 6 be modified to allow for the transmission of
the monitoring reports through eDMR and mail or email."
Response: Section A6 follows the Electronic Reporting Rule adopted by the Division in 2016. Therefore,
the section cannot be modified.This was communicated to the Permittee and ORC via teleconference
on March 16, 2020.

3rd
Draft Fact Sheet Addendum
Comment: "In Section A4,the schedule of compliance includes completing an action plan within one
year of the permit,taking action within 2 years of the permit,and being compliant within 3 years of the
permit. Further, the approved action plan would become an enforceable part of the permit.At the same
time, draft permit allows for the Permittee to apply for a permit modification based on an RPA with at
least 24 data points of copper and silver concentrations. We would propose that the action plan would
be due 2 years following the permit, with the actions taken in year 3, and compliance in year 4.This
would allow for 24 monthly samples to be acquired and submitted as part of the action plan.The
additional testing might necessitate a change in the action plan based on the results of the reasonable
potential analysis."
Response:The compliance schedule has been modified to be extended to four years, with the first two
years requiring the Permittee to submit a summary of actions taken to reduce Copper and Silver
concentrations toward permit limits; the third year requiring the Permittee submit a Corrective Action
Plan; and limits becoming effective by the fourth year. The paragraph that refers to applying for a
permit modification to reassess reasonable potential of Copper and Silver to exceed water quality
standards was removed from the permit. These changes were discussed and agreed-upon with the
Permittee, ORC and consultant via a webmeeting on March 19, 2020.
Please note,the Permittee can submit sampling data for review and a permit modification at anytime.
At least 24 samples should be submitted for a rerun of a reasonable potential anaylsis. Sampling does
not constitute actions towards compliance with permit limitations; however, actions such as submitting
a revised Headworks Analysis (based on the new limitations), reissuance of SIU permits that implement
the new limits, and collection system sampling to assess and identify sources of silver and copper are all
acceptable.

A. (6.) 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 Section 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)I
The Permiee 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/DWR/Water Quality Permitting Section
Attn: Central Files
1617 Mail Service Center
Raleigh,NC 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 Permiee must electronically report the following compliance
monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
Page 9of11

Permit NC0020664
• 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:
https://www.federalregi ster.gov/documents/2015/1 0/22/2015-24954/national-pollutant-discharge-
elimination-system-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 five(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:
http://deq.nc.gov/about/divisions/water-resources/edmr
