Dear Mr. Hudson:
Based on your request to renew the subject NPDES permit, the Division of Water Resources
(DWR or the Division) hereby transmits this draft for your review and comment. Please review it
carefully to ensure your understanding of the limits and monitoring conditions, and to correct
discrepancies, if any.
Concurrent with this notification, the Division will solicit public comment on this draft by
publishing a notice in newspapers having circulation in the general Union County area, as
required by the NPDES Program. Please provide your written comments, if any, to
DEQ/DWR/NPDES no later July 15,2019 (approximately 30 days after receiving this
document). Your written comments are welcome but are not mandatory.
Changes for Renewal. The Division understands that you have made no significant changes in
your wastewater treatment processes since last renewal. We have therefore made only minimal
changes to your permit by updating your facility description and site map and have also added
relevant regulatory citations to the permit for your convenience.
Division records show that you have successfully registered with the eDMR Program. Please be
reminded that until the state's eDMR application is approved compliant with EPA's Cross-Media
Electronic Reporting Regulation (CROMERR), all permittees must continue to submit hardcopy
of DMRs as backup to eDMR reporting [see permit section A. (3.)].

2. A flow totalizer may\ esejii ilieu of a continuous recording device. Should flow become
inconsistent and/or highlyyanable or should the Mooresville Regional Office deem this method
insufficient to properly characterize wasteflow, a continuous recording device may be required.

Class PC-1
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 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
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 beyerformed 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 7sions.
r
All toxicity testing results required as part of this permit condition willentered on the Effluent
Discharge Monitoring Form(MR-1) for the months in whi6 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: �� ^ \\

days after the end of the report' gperiod for which he eport iss made.-Test data shall be complete,
accurate, include all supporting g chemical/phyi measurements and all concentration/response data, and
be certified by labo-atory_supervisor and ORC or ap roved designate signature. Total residual chlorine of
the effluent toxicity sample must bemmeasured anddreported 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,pe number,pipe number, county, and the month/year of the report
with the notation of"No Flowin'thee 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
