Subject: Draft NPDES Permit NC0021229
Old Fort WWTP
Grade III Biological WPCS
McDowell County
Dear Mayor Hensley:
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. We
understand from your renewal application that there have been no significant changes to the treatment
system other than some components that are not currently active. Your facility has recently restarted your
pretreatment program with the addition of an industrial discharge to your system. Some changes in the
draft permit are related to the addition of the pretreatment program. There are several changes in the draft
from the existing permit. These changes are summarized below.
• Regulatory Citations—Language has been added where necessary in the permit to provide
regulatory citations for permit requirements.
• Electronic Reporting—Permit language has been updated to be consistent with the finalization of
federal requirements for electronic reporting.
• Parameter Codes—Codes have been updated as necessary in the table in Section A.(1).
• Treatment Components—Language on the Supplement to the permit cover sheet has been
modified to reflect your request to note system components that are not currently active.
• Effluent Pollutant Scan—With the reactivation of your pretreatment program and the addition of
industrial discharges a requirement to perform the pollutant scan has been included in your permit
for both effluent limits pages. The scan components must be conducted three times during the
permit cycle in accordance with the conditions of Part I, Section A.(5)in the permit.
• Dissolved Oxygen(DO)Monitoring Limit—Your facility discharges to surface waters classified
as Trout waters(Tr). These waters carry a more stringent instream water quality standards,
including for DO. The draft permit increases the required DO level in your discharge from 5
mg/L to 6 mg/L in keeping with the requirements for Tr classified waters. This change is
included in both effluent limits pages.

• Whole Effluent Toxicity(WET)Monitoring-With the addition of industrial components to your
discharge there are increased possibilities for pollutants that may exhibit toxic effects in the
waters. The Division has reviewed the current proposed permit requirements,past facility results
when WET testing was required and considered the level of parameter characterization that will
be afforded with the Effluent Pollutant Scans. The Division has concluded that WET testing
requirements are appropriate when your facility moves into expansion under your 0.90 MGD
requirements. WET testing is proposed quarterly under the 0.90 MGD requirements. Please
note,however,that the requirements of the Effluent Pollutant Scan include additional WET
monitoring that will be required prior to renewal[see Part I Section A.(5)].
• Ammonia Nitrogen(NH3-N)Monitoring—In the current permit you monitor 2 times per month
for NH3-N and have summer and winter effluent limits. Recent review by Division staff has
noted that 15A NCAC 2B.0404(c)requires that winter waste load allocations for oxygen
consuming waste be no less stringent than 2 times the summer waste load limit. To meet this rule
requirement winter limits for NH3-N are being adjusted in this permit.
These changes will reduce the monthly average limit to 11.8 mg/L for the 0.50 MGD Effluent
Limitations. The weekly max of 35 mg/L will remain unchanged. For the 0.90 MGD Effluent
Limitations the winter limits will be reduced to 7.4 mg/L and 22.2 mg/L. Based on the data
reviewed from the previous permit cycle it appears that the proposed change in the winter limits
will be well within the values that this treatment system routinely attains.
• Cooper(Cu)Monitoring: A reasonable potential analysis(RPA)was performed on data from the
time period summarized above for Cyanide,Mercury and Cooper. No changes are proposed for
Cyanide or Mercury monitoring. The RPA analysis of the Cooper data indicates the need for an
adjustment of the water quality based effluent limit at the expanded 0.90 MGD flow. The permit
proposes a monthly average limit of 35.56 mg/L and a daily max of 41.55 mg/L. Should the
facility need to move to activate the 0.90 MGD flow special attention should be given to actions
that would assure compliance with the Cu limits.
Please note that the previous permit had established a compliance schedule for meeting the Cu
limits. That schedule required compliance with the Cu limits as of January 1,2020. The
compliance schedule language has been removed from the permit text.
• A reopener clause has been added to the permit [A.(4)] specifically related to the addition of
industrial discharges to the treatment system.
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.The latest
version is available at https://bit.lv/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 general
circulation in the Columbus County area soliciting public comments on this draft permit. Please provide
any written comments you may have to me no later than 30 days after receipt of this draft permit.

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 22%.
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 11 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 electronically using the
Division's eDMR system for the months in which tests were performed,using the parameter 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:
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,[e-mail].
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.

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:

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.
