Subject: Draft NPDES Permit Renewal
Permit NC0023906
Hominy Creek WRF
Wilson County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr.Pridgen:
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 no reasonable potential to
violate state water quality standards,the monitoring requirements for total copper and
dichlorobromomethane have been removed from the permit[See A.(1.)].
• Some of the wording has changed in Special Condition A.(5.), Chronic Toxicity Permit
Limit,please review each paragraph carefully.
• Special Condition A.(6.)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.
• The City of Wilson reported Total Silver and Total Lead at less than detection, with a
detection level < 5 µg/L and < 10 µg/L, respectively, in their discharge monitoring reports.
The City's chronic allowable discharge concentration is 0.064 µg/L for Total Silver and 5.42
µg/L for Total Lead. DWR's laboratory identifies the target Practical Quantification Limits
(PQL)as 1.0 µg/L for Total Silver and 2.0 µg/L for Total Lead. 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 Lead down
to a PQL below the allowable discharge concentration. While no monitoring requirement has
been added to the permit for Total Silver or Total Lead at this time, the Division can add a
limit or add limits during the next renewal if this regulation is not satisfied.
• 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.)].
• 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.)].
• Regulatory citations have been added to the permit.
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://hit lynBZ4xxx 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 Wake County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following:NCDEQ/DWR,NPDES
Permitting Branch, 1617 Mail Service Center,Raleigh,NC 27699-1617 no later than 30 days
after receipt of 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 fmal permit. If you have questions concerning this
draft permit,please call me at(919) 707-3609 or by email at [e-mail].

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
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 quaker 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 whic s re performed, using the j arameter code
TGP3B for the pass/fail results and THP3B for the Chroni lue. Additionally,DWR Form AT-3

Test data shall be complete,accurate, include all su• • . g chemical/physical measurements and all
concentration/response data,and be certified by la• atory supervisor and ORC or approved
designate signature. Total residual chlorine of+;; uent 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
fop*indicating the facility name,petit 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 requirl during the following month.Assessment of toxicity compliance is based on
the toxicity testing qulrfer,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.
