Subject: Draft NPDES Permit NCO077763
Belmont WTP
Grade I Physical Chemical WPCS
Gaston County
The Division has reviewed your request to renew the subject permit. Please reviewthis draft carefully to ensure a
thorough understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
1. The supplement to permit cover sheet was updated for facility description and receiving stream
information.
2. The facility classification Grade I Physical Chemical Water Pollution Control System (WPCS) was
added to the effluent page.
3. For consistency with the permitting strategy for a conventional technology water treatment plant the
following changes were made to the effluent limitations and monitoring requirements (condition A. (1.):
Continuous flow recording is required for flows greater than 50,000. If not present, the facility will
have until July 31, 2025 to install a continuous flow recording meter.
b. For flows greater than 0.5 MGD, weekly monitoring is required for limited parameters. The
monitoring frequency for Total Suspended Solids (TSS), pH, and Total Residual Chlorine (TRC) is
changed to weekly.
pH monitoring and limitation is required by the WTP strategy. Due to ambient conditions in the
receiving stream being outside the water quality standard for pH, this parameter will not be limited.
However, the stream standard for pH would still apply with the following footnote: The pH shall not
be less than 6.0 standard units nor greater than 9.0 standard units unless ambient river conditions
prevent compliance with this range.
d. Total Nitrogen and Total Phosphorus are required for discharges greater than 0.05 MGD
5. 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, has been added to this permit at a monitoring frequency of
quarterly.
6. Concurrent sampling with the WET testis no longer required.
7. The chronic toxicity monitoring special condition A. (2.) was updated.
8. The electronic reporting permit special condition A. (3.) was updated -
The permit map was updated. Outfall 001 coordinates were adjusted to Latitude 3 50 14' 33", Longitude
-810 00' 50".
Please note that the Catawba River is listed as an impaired waterbody on the 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 hops://bit.ly/2BZ4xxx and can be viewed
online or downloaded as a PDF file.
With this notification, the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Gaston County area, per EPA requirements. Please provide your
comments, if any, to me at the address below no later than 30 days after receiving 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 the draft, please contact meat 919-707-3618, or via e-mail at

NPDES Permit NCO077763
A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING (QUARTERLY)
[15ANCAC 02B.0500 et seq.]
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," (Revised December 2010, or subsequent versions).
The effluent concentration defined as treatment two in the procedure document is 0.33%. The testing shall be
performed as a Ceriodaphnia dubia 7-day pass/fail test. 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 NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered electronically using the Division's
eDMR system for the month in which it was performed, using the parameter code TGP3B. Additionally, DWR
Form AT-1(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 and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. 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, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
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.

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. The eDMR system may be accessed at:
https:Hdeg.nc.gov/about/divisions/water-resources/edmr.
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 following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
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
Clean Water Act (CWA) Section 316(b) Annual Reports.
➢NPDES Electronic Reporting Rule — Phase 2 Extension. EPA is proposing to extend the Phase
2 deadline from December 21, 2020 until at least December 21, 2023. The current compliance
date will be extended if the implementation date is extended as a final regulation change in the
federal register.

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.fedcralregister.gov/documents/2015/10/22/2015-24954/national-pollutant- discharge-elimination-
sy stem-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 fromthe 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 5 y ears 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 waiverby 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://deg.nc.gov/about/divisions/water-resources/edmr
