Draft Permit Review
Page 2 of 2
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 submitted for 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,has been added to this permit at a monitoring
frequency of quarterly. See Section A. (1)Effluent Limitations and Monitoring Requirements.
eDMR Submittals: DWR records show that your monthly reporting requirement is currently
waived. Please note that upon commencing discharge,Federal regulations require electronic
submittal of all discharge monitoring reports(DMRs)and program reports [See Special
Condition A. (3.)]. If you fill out and submit to DWQ an electronic signature agreement,you
will no longer required DMR hardcopy as back-up to the eDMR.
Following the mandatory 45-day Public Comment period,the Division will review all pertinent
comments, if any,and take appropriate action prior to issuing an NPDES permit final. If you have
questions,please email me,Joe R. Corporon,P.G. at[joe.corporonAncdenr.gov] In deference to
Covid 19, emergency remote permitting is currently mandated.Please forward all correspondence
via email.
Sincerely,

A. (2.) ACUTE TOXICITY PASS/FAIL LIMIT (QUARTERLY)
[15A NCAC 02B .0200 et seq.]
The permittee shall conduct acute toxicity tests on a Ouarterlv basis using protocols defined in the North Carolina
Procedure Document entitled"Pass/Fail Methodology for Determining Acute Toxicity in A Single Effluent Concentration"
(Revised December 2010 or subsequent versions).The monitoring shall be performed as a Mysid Shrimp(Mysidopsis
bahia)24-hour static test.The effluent concentration at which there may be at no time significant acute mortality is 90%
(defined as treatment two in the procedure document).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.
Should any single quarterly monitoring indicate a failure to meet specified limits,then monthly monitoring will
begin immediately until such time that a single test is passed.Upon passim ,this Monthly test requirement will
revert to quarterly in the months specified above.
All toxicity testing results required as part of this permit condition wil ered. . e Effluent Discharge Monitoring
Form(MR-1)for the month in which it was performed,using the am r code T t .Additionally,DWR Form AT-
2(original)is to be sent to the following address:

Completed Aquatic Toxicity Test Forms shall be filed with ienc ection no later than 30 days after the end
of the reporting period for which the report is made.
Test data shall be complete and accurate and include 1 suppo chemic sical measurements performed in
association with the toxicity to well as 411 do /re ponse d .Total residual chlorine of the effluent toxicity sample
must be measured and repo d i ..chlorine is oy o ' inf n of the waste stream.
Should there be no disch of flow fro e i 'ty during o in which toxicity monitoring is required,the
permittee will complete the' rmation to t a top of the aquatic toxicity(AT)test form indicating the facility
name,permit number,pipe n r,county, the o th/year of the report with the notation of"No Flow"in the
comment area of the form.The shall be u mitt the Water Sciences Section at the address cited above.
Should the permittee fail to monitor 'ng a on in which toxicity monitoring is required,then monthly monitoring
will begin immediately until such tim sin e test is passed.Upon passing,this monthly test requirement will revert
to quarterly in the months specified abo . essment of toxicity compliance is based on the toxicity testing quarter,
which is the three-month time interval that egins 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 either these monitoring requirements 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. I
NOTE: Failure to achieve test conditions as specified in the cited document,such as minimum control organism survival
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.
USE OF A DIFFERENT TEST ORGANISM
The permittee may request the use of a different test organism upon documentation that the alternate test organism would
provide an equal or greater level of protection and is appropriate based on the characteristics of the discharge and •
receiving stream. Such documentation would consist of one of the following:
Page 4 of 7

Permit NC0088811
WWTP Class I
1. For saltwater classified streams,a fathead minnow may be assigned as the acute testing species if the
salinity of the receiving stream at the point of discharge is<5 ppt throughout the tidally influenced cycle.
This determination may be based on the best professional judgment of DWR staff or data collection
provided bythepermittee and approved byDWR staff. This evaluation should include vertical profiles of
PP
salinity/conductivity measurements at both high tide and low tide over several 24-hour cycles.
2. Three consecutive"side-by-side"tests with results indicating that the alternate test organism is as or more
sensitive to the facility's effluent. Each test series would consist of two separate toxicity tests conducted on
the same sample of effluent with the length of exposure specified by the permit,the only difference between
the tests being the organism used.
3. An alternate plan developed by the permittee and approved by the Aquatic Toxicology Unit that
demonstrates an equal level of protection is offered by the test organism.
For items 2 and 3,it must also be demonstrated that viable and standardized culture techniques are available for that
organism and standardized testing methodologies have been developed and validated. This demonstration should meet
guidance provided by EPA in Section 6 of EPA-821-R-02-012,Short Term Methods for Estimating the Acute Toxicity of
Effluents and Receiving Waters to Freshwater Organisms.Fifth Edition,2002 Re uests to use a different test organism
and supporting documentation should be sent to NC DWR,WSS at the ad s 's above.
