Subject: Draft New NPDES Permit NC0089737
Franklin WTP
Macon County
Dear Ms. Woodard:
Enclosed with this letter is a copy of the draft permit for the proposed conventional water treatment
plant discharge. Please review this draft carefully to ensure your thorough understanding of the
information, conditions, and requirements it contains.
The requirement to begin 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 Section A. (4)]. For information on eDMR,registering for eDMR and obtaining an eDMR
user account,please visit the following web page: https://deq.nc.gov/about/divisions/water-
resources/edmr. For information on EPA's NPDES Electronic Reporting Rule,please visit the following
web site: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule.
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 dicharge, for each facility monitoring these metals in order to
calculate permit limitations. Effluent hardless and instream hardness sampling,upstream of the
discharge,has been added to this permit ata monitoring frequency of quarterly. See Section A.(1)
Effluent Limitations and Monitoring Requ rements.

With this notification, the Division will solicit public comment on this draft permit by publishing a
notice in newspapers having circulation in the general Macon County area,per EPA requirements.
Please provide your comments,if any,to me 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 p rmit. If you have questions concerning the draft,please
contact me at 919-707-3619, or via e-mail [[e-mail]].

1. The permittee shall submit dislcharge monitoring reports electronically using the NC DWR's eDMR
application system [see[see Section h. (4)].
2. Limit and monitor only if the facility adds chlorine or chlorine derivatives to water that is eventually
discharged. The Division shall consider all effluent TRC values reported below 50 µg/L to be in
compliance with the permit However,the Permittee shall continue to record and submit all values
reported by a North Carolina'certified laboratory(including field certified),even if these values fall
below 50 µg/L.
3. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent
metals(cadmium, copper, lead,nickel, silver, and zinc).
4. The Permittee shall sample instream hardness,upstream of the facility's discharge. The sample shall be
representative of the hardness in the receiving stream. If the Permittee is a member of the Monitoring
Coalition Program, sampling for instream hardness may be waived as long as the Monitoring coalition
agrees to sample hardness at the nearest upstream location,at a minimum frequency of quarterly, and the
Permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being
monitored by the Coalition is representative of the receiving stream for this discharge. The Permittee is
responsible for submitting instream hardness test results with its permit renewal application package. If
Page 3 of 8

A. (2) CHRONIC TOXICITY PASS/FAIL PERMIT MONITORING(QUARTERLY) '
[15A NCAC 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 1.92 %. 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 on the Effluent
Discharge Monitoring Form(MR-1) 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:

days after the end of the{reporting.period for which theteport-is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with,the toxicity testy, as well as all dose/response data. Total residual chlorine
of the effluent-toxicity-sample mustbe,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,

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
Page 7 of 8

Permit NC0089737
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:
