A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[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 on the Effluent Discharge
Monitoring Form(DMR-1)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
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh,North Carolina 27699-1623
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.
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, 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.

reporting 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:

ATTENTION: Central Files/eDMR
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.

Permit NC0086517
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be valid
for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re-applies for and is granted a new temporary
waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr

Fact Sheet
Renewal 2015 --NI'UFS Permit NC0086517
['age

Compliance History—The facility had four limit violations for 1,2-cis-dichloro-ethylene [permit limit is 4.9
pg/L] which included one monthly and one daily in February 2012 and April 2014. For 1,2-cis-dichloro-
ethylene the human health standard is 720 pg/L and the water supply standard is 60 pg/L. The stream is an
unnamed tributary that is considered to have a 7Q10 of zero. The stream is classified C waters; therefore,
the human health standard is applicable. The previous permit limit [4.9 pg/L] was more restrictive than the
applicable human health.
For Renewal—This permit reflects discharge at Outfall 001. DWR updated the following:
• for Oil & Grease [00556] remains the same for submitting DMR/eDMR, but uses test EPA method
1664 (SGT-HEM)with results in mg/L for Outfalls 006 & 007
• added Electronic Reporting- Discharge Monitoring Reports page Section A. (3.).
• added updates to facility map, outfall locations and parameter codes
• updated Tetrachloroethene(PCE) limit to 3.3 pg/L in accordance with current human health standards
• updated 1, 2-cis-dichloroethene limit to 720 pg/L in accordance with current human health standards.
Stream— Discharge from WWTP for Outfall 001 is into an unnamed tributary to Irwin Creek [Stream
Segment 11-137-1]. The segment is listed as"impaired" for Hg in Fish tissue, poor fish community,Zn,
Pb and Cu in the 2014 North Carolina Integrated report and 303(d) list.
RPA—A Reasonable Potential Analysis(RPA)was conducted on copper, lead,zinc, iron,tetrachloroethene,
I, 2-cis-dichloroethene, chloroform,trichloroethene and 1,2-dichloroethane because Discharge Monitoring
Reports (DMRs) reported concentration above method-detection levels (MDLs) for the past three years and
one month (37 months) [Jan2012-Feb2015] of data. [See attached RPA summary sheets.]
• 1, 2-cis-dichloroethene limit was removed because the RPA did not show reasonable potential to
exceed the human health standard (HH)of 720 pg/L.
• Tetrachloroethene(PCE) showed reasonable potential to exceed the human health standard of limit
(HH)of 3.3 pg/L. The limit was updated to 3.3 pg/L based on this standard.
