Subject: 2nd 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 second draft NPDES permit renewal for your facility.
This second draft is being sent for review and public comment in light of the proposed compliance
schedule, which represents a relaxation of prior limitations, and this requires a second Public
Notice. 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 changes were made to the first draft permit sent to you on October 28, 2019:
• To provide an opportunity for the Town to collect additional Total Copper and Total Silver
data for possible reassessment with water quality standards, and to 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. If the Town wishes to have
the Division reassess Total Copper and/or Total Silver limitations based on additional data,
a permit modification must be applied for with submitted data [See Special Condition A.
(4.) Schedule of Compliance for Total Copper and Total Silver].
• 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.
A detailed response to the comments received from the Town of Spindale on November 26, 2019 1
and subsequent communication can be found in the Fact Sheet Addendum attached to this letter.

The fmal permit maintains the following significant changes identified in the letter sent on
October 28, 2019:
• 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.
• Per the results of instream waste concentration (IWC)-based calculations for ammonia-
nitrogen,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. (4.)
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 Special Condition, 2nd species Toxicity Testing Requirements for municipal
permit renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
Page 2 of 3

• 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. (5.)].
• 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 as well as
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 [phone] or by email at [e-mail].
Sincerely,

Fact Sheet Addendum
Only the Permittee provided comments to the Spindale WWTP (NC0020664) draft permit, public noticed
on November 2, 2019. Comments by Scott Webber,Town of Spindale (Permittee), are as follows:
• The Town requested an extension of the comment period, stating that it was unaware of the
comment due date, and unaware of the public notice.As the permit writer responded to a similar
extension inquiry by the facility's consultant engineer,the Division does not make extensions to any
one party in the interest of fairness to all stakeholders in the public comment period.An affidavit for
the public notice was received by DWR, stating a publication date of November 2, 2019.The
comment period ended December 5, 2019.
• The Town requested acceptance and review of additional effluent copper and silver data collected
over a three-week period ending December 17, 2019. The town argues the limits in the draft permit
"may have been based in part on incomplete or faulty data."
• The Town requested a "grace period" [i.e., a compliance schedule] of at least six months for Copper
and Silver limits to become effective, allowing time for increased sampling and investigation of
possible sources.
• The Town requested moving the upstream sample point to a safer location yet to be specified.
While the proposed location is argued to be accessible via the bridge only,the permit writer visited
the location off of a small turnout with the ORC and consultant engineer to observe the outfall. The
proposed upstream location is accessible from the outfall location.To make the upstream location
more representative of the receiving water, it needed to be at or downstream of the confluence of
Hollands and Catheys creeks, and upstream of the outfall.
The Division addressed the above comments via e-mail to the Permittee on December 19, 2019,
explaining the comment period and providing a pdf of the Public Notice affidavit.The Division allowed
the Permittee's request for time to collect additional data and propose an alternate upstream sampling
location.The Permittee's response was received on January 9, 2020.
The Permittee's response included a request for a one-year delay in implementing the Copper and Silver
limits to allow time for further sampling to be reassessed via an RPA, providing one set of influent and
effluent data collected in December 2019.The original upstream location was proposed as the safest
location for sampling.
The Division made the following permit changes based on evaluation of the Permittee's requests:
• A 3-yr compliance schedule has been added to meet Copper and Silver limits.The schedule includes
an option to reassess reasonable potential of Copper and Silver to exceed their water quality
standards upon receipt of additional data and an application for a permit modification.
• The original upstream monitoring location will be reinstated for safe access,finding that
comparative Hardness data between the original location and the proposed location were similar at
< 25 mg/L.

other than the test species currently required in this permit.The second species tests should be conducted
either quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests
performed at least annually in the four and one half year period prior to the application. The second
species tests must be multiple concentration (5 concentrations plus the control). These tests shall be
performed for acute or chronic toxicity, whichever is specified in this permit. POTWs performing
NPDES chronic Ceriodaphnia testing should perform chronic Fathead minnow testing. POTWs
performing NPDES acute Fathead Minnow testing should perform acute Ceriodaphnia testing. POTWs
performing NPDES chronic Mysid shrimp testing should perform chronic Silverside Minnow testing.
The second species toxicity test results shall be filed with the Aquatic Toxicology Branch at the
following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E
(Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal
application to the NPDES Permitting Unit.

If within two (2) years of the permit effective date or 24 data points have been collected, and the data
suggest that Total Copper and/or Total Silver limits are no longer required, the Permittee may apply for
a permit modification to request a reassessment of these parameters' reasonable potential to exceed their
respective water quality standards.

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)1
The Permittee 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 Permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and

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.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-di scharge-
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:
