Subject: Draft NPDES Permit Renewal
Permit NC0090131
Mill Creek WWTP
Cleveland County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Duncan:
Enclosed with this letter is a copy of the Draft NPDES permit for your proposed facility. Please
note that discharge from this proposed facility shall not commence without receipt of an
Authorization to Construct permit for the construction of the proposed facility, an Engineer's
certification for the completion of the authorized construction and notification to the Division of
intent to discharge at least 7 days prior to discharge. Please review this draft carefully to ensure
thorough understanding of the requirements and conditions it contains. There are several
requirements in the draft permit for this proposed discharge, including the following:
• A facility components list has been developed based on the information provided in the
permit application and Engineering Alternatives Analysis(EAA) submitted by the City.
• As the facility class for the proposed Mill Creek WWTP is Grade IV per 15A NCAC 08G
.0302, monitoring requirements for several parameters, as outlined in 15A NCAC 02B .0508,
have been included in the permit to reflect a Grade IV facility [See A.(1.)].
• To monitor influence of the discharge on the receiving stream and in accordance with
15A NCAC 02B .0508, instream monitoring requirements for dissolved oxygen,temperature,
fecal coliform, TKN,nitrate+nitrite,total nitrogen and total phosphorous have been added
to the permit [See A.(l.)].
• As provided in the January 7,2022 Speculative Effluent Limits letter, limits for flow,
BOD,TSS,ammonia,fecal coliform,dissolved oxygen,pH,total residual chlorine, and total
phosphorous have been added to the permit [See A.(1.)].
• To ensure best management practices are in place to mitigate the introduction of total
mercury into the stream, Special Condition A.(4.)Mercury Minimization Plan has been added
to the permit.
• The Division is implementing dissolved metals standards in all permits,per the 2016
revisions to State water quality standards. As such,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.)].
• A special condition to monitor effluent PFAS chemicals quarterly has been added to the
permit,to be effective six(6)months after EPA has a final wastewater method in 40 CFR136

method published in the Federal Register [See Special Condition A.(6.) PFAS Monitoring
Requirements].
• To monitor effluent toxicity, Special Condition A.(3.), Chronic Toxicity Permit Limit has
been added to the permit.
• Special Condition A.(4.) Additional Monitoring Requirements for Permit Renewal has
been added to the permit. Per 40 CFR 122.21(j)(4), as this is a new discharge, an effluent
pollutant scan be conducted and submitted to the Division within 24 months of the
commencement of discharge, and once per year for the 2 following years. 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.
• To notify the Division of commencement of discharge and connection of nearby systems,
Special Condition A.(6.)Notification of Start-Up has been added to the permit.
• 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.(7.)].
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/3k5NFaL and can be viewed online or downloaded as a PDF file.

A.(2.) CHRONIC TOXICITY PERMIT LIMIT(QUARTERLY)
[15A NCAC 02B .0200] [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 January,April,July,and October.
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:
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.

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

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

3. How to Request a Waiver from Electronic Resorting
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
