NPDES Permit NCO049409
Waynesville WTP
Class PC-1
Haywood County
Dear Mr. Gregg:
Director
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached final NPDES discharge permit. This permit is
issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum
of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October
15, 2007 (or as subsequently amended).
The final permit includes the following significant changes from the existing permit:
➢ Section A. (3) has been added to require electronic submission of effluent data. Federal
regulations require electronic submittal of all discharge monitoring reports (DMRs).
➢ Regulatory citations have been added to the permit.
➢ Total hardness, total zinc, and turbidity monitoring have been added to the permit.
➢ Footnotes have been updated for fluoride and ammonia nitrogen.
➢ The HUC code has been updated on the map.
➢ Flow sample type changed from Grab to Instantaneous (per 2012 modification).
➢ Measurement frequency changed from Continuous to 2/month (per 2012 modification).
It is the recommendation of the Division that alternatives to discharging wastewaters be explored.
As Allen Creek is classified as C-Trout waters, alternative disposal options could benefit both the
permittee and the environment. Please contact the Division for any assistance that may be needed in
researching alternatives.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such
demand is made, this permit shall be final and binding.

Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the Division's eDMR system. See
Condition A. (3.).
2. The Permittee shall record both flow -rate and discharge duration. Flow shall be reported as the sum of two effluents.
3. Total Residual Chlorine (TRC) — 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 50µg/L to be compliant with
this 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 501tg/L.
4. Fluoride should be monitored if the Permittee backwashes with fluoridated finished water.
5. Ammonia Nitrogen should be monitored if the Permittee uses chloramines (adds ammonia to chlorinated water) for
secondary disinfection prior to backwashing.
6. Zinc should be monitored if the Permittee adds zinc orthophosphate as a corrosion inhibitor prior to backwashing.
7. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals (cadmium,
copper, lead, nickel, silver, and zinc).
8. 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 Coalition membership is cancelled or the Coalition terminates instream hardness sampling at the approved
station, the Permittee will immediately notify the Division and resume sampling for instream hardness, upstream of its
discharge.
9. Chronic Toxicity WET Testing Quarterly P/F (Ceriodaphnia @ 90 %); see section A. (2.).
Condition: The Permittee shall discharge no floating solids or foam.
A. (2.) CHRONIC TOXICITY MONITORING - (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. 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.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
Page 4of8

Permit NCO049409
code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-
3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
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, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. 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, monitoring
will be required during the following month. Assessment of toxicity compliance is based on the toxicity
testing quarter, which is the three month time interval that begins on the first day of the month in which
toxicity testing is required by this permit and continues until the final day of the third month.
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.
A. (3.) ELECTRONIC REPORTING OF DISCHARGE 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 H of this permit
(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
Page 5 of 8

Permit NC0049409
• Section E. (5.) Monitoring Reports
1. Reporting Requirements ISupersedes Section D. (2.) and Section E.15.) tall
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 DENR / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 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
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)].
Page 6 of 8

Permit NC0049409
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:
http://www2.epa. gov/compliance/final-national-pollutant-discharge-elimination-system-npdes-electronic-
re ortin -rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Re ortin
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.
Information on eDMR and the application for a temporary electronic reporting waiver are found on the
following web page:
