Subject: Draft NPDES Permit Renewal
Permit NC0020656
Leith Creek WWTP
Scotland County
Grade IV Biological WPCS I
SIC Code 4952
Dear Mr.Nichols III:
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:
• Based on the reasonable potential analysis(RPA) showing reasonable potential to violate
state water quality standards, total copper and total zinc limits have been added to the
permit along with monthly monitoring [See A. (1.)].
• Per the results of instream waste concentration (IWC)-based calculations for ammonia
nitrogen,ammonia nitrogen limits have been revised[See A. (1.)].
• To provide an opportunity for the City to develop a plan to assess sources of total copper in
order to come in compliance with the limits in Section A. (1.), a 3-year schedule of
compliance has been added to the permit [See Special Condition A. (4.) Schedule of
Compliance for Total Copper Limitations].
• Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BOD5,NH3-
N, Total Suspended Solids and Fecal Coliform have been reduced to twice per week[See
A.(1)].
• Based on review of instream monitoring data, monitoring requirements downstream at
NCSR 1612 (D1)have been removed from the permit[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 City reported Total Silver and Total Cadmium at less than detection,with a detection
level < 5 µg/L and < 2 pg/L, respectively, in their effluent pollutant scans. The City's
chronic allowable discharge concentration is 0.194 µg/L for Total Silver and 1.903 µg/L
for Total Cadmium.DWR's laboratory identifies the target Practical Quantification Limits
(PQL)as 1.0 µg/L for Total Silver and 0.5 µg/L for Total Cadmium. 15A NCAC 2B .0505
(e)(4)requires that all test procedures must produce detection and reporting levels that are
below the permit discharge requirements.If no approved methods are capable of achieving
a detection level below the permit discharge requirement(or allowable concentration)the
method with the lowest detection level must be used. The City shall test for Total Silver
and Total Cadmium down to a PQL below the allowable discharge concentration. While
no monitoring requirement has been added to the permit for Total Silver or Total Cadmium
at this time, the Division can add a limit or add limits during the next renewal if this
regulation is not satisfied.
• Based on the Mercury TMDL evaluation showing mercury values reported at levels > 1
ng/L and since the permitted flow is greater than 2 MGD, wording in Special Condition
A.(5.)Mercury Minimization Plan has been modified toward its maintenance.
• 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(2021,2022,and 2023). 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.
• A notation was made concerning the Electronic Reporting Rule—Phase 2 Extension.EPA
is proposing to extend the Phase 2 deadline from December 21, 2020, to December 21,
2023.The current compliance date will be extended if the implementation date is extended
as a fmal regulation change in the federal register.
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A.(1.)].
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 Scotland County area, soliciting public comments on this draft permit.

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.
b. There shall be no discharge of floating solids or visible foam in other than trace amounts.
A.(2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0200 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 31%.
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
February,May,August,and November.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 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:
Attention: North Carolina Division of Water Resources

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,

A.(6.) 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 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)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. 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
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.
Page 4 of 12

Permit NC0020656
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,to 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

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.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
