Subject: Draft NPDES Permit Renewal
Permit NC0020940
Murphy WWTP
Cherokee County
Grade III Biological WPCS
SIC Code 4952
Dear Ms. Payne:
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:
• Per 15A NCAC 2B .0508, since the facility discharges greater than 1 MGD of treated
wastewater and is in the Hiwassee River Basin,the monitoring frequency for total nitrogen
and total phosphorous has been increased to quarterly[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 Murphy reported Total Silver at less than detection,with detection levels<
50.0 µg/L and<5.0 µg/L in the Discharge Monitoring Reports. The Town's allowable
discharge concentration is 2.739 µg/L 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. Quarterly monitoring for total silver has been
maintained in the permit [See A.(1.)].
• 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(2020, 2021, and 2022). 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.
• 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 Special Condition A. (4.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A. (1.)].
• Regulatory citations have been added to the permit.
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 Cherokee 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.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal
facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to
additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA
requires four(4)toxicity tests for a test organism other than the test species currently required in this
permit. The multiple 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. These tests shall be performed for acute or chronic toxicity,
whichever is specified in this permit. The multiple 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.
A.(4.) ELECTRONIC REPORTING OF MONITORING REPORTS
[G.S. 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 special condition 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)t
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/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Page 7 of 9
Permit NC0020940
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
• 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-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 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.
