A. (5) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 0.75%.
The permit holder shall perform at a minimum, auarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised - February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July and October. Effluent sampling for this testing 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- February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR -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, DWQ
Form AT -3 (original) is to be sent to the following address:

BACKGROUND
United Chemi -Corn owns and operates a manufacturing facility for aluminum electrolytic
capacitators in Ashe County. This type industrial process is not a listed EPA manufacturer
category and thus has no designated federal effluent guidelines. Currently, four outfalls are
covered under this permit. The Division has determined that this facility meets the criteria as a
minor discharger.
Outfalls 001 discharges on a regular bases and includes non - contact cooling water, A/C
condensate, boiler blowdown, deionization backwash wastewater, potential episodic process
wastewater, potential spills/wash water, and stormwater. Per flow schematic (typical flow):

Some chemical additives are in the boiler blowdown and no biocides or chlorination are used.
There is no treatment process associated with Outfall 001 wastewater. A priority pollutant
analyses (PPA) for Outfall 001 was submitted with the renewal application.
The application list ethylene glycol and gammabutratactone as potential chemicals in outfall 001
discharge as a result of spills and condensation from various process operations that may get into
the outfall wastewater stream as trace amounts. By design the primary process wastewater is
collected and transported off site for disposal. But as an emergency contingency plan and as a
last resort to sustain operation the manufacturer has been granted the flexibility to temporarily
add process wastewater to this discharge.
Outfall 003 discharges on intermittent basis, although historically no discharge has been reported
in recent years. Wastewater sources for outfall 003 are A/C condensate and stormwater. There is
no chlorination or treatment process associated with this outfall wastewater.
Outfall 006 discharges the facility treated domestic wastewater on a regular basis but it is
diminutive with only an IWC less than 0.1 %. There are grease traps on the kitchen sinks.
Treatment includes an influent screen, followed by an Imhoff Cone, collection /dosing tank, and
two parallel sand filters. There is no disinfection /chlorination treatment associated with this
effluent. The stream dilution factor meets guidance for not imposing fecal limits.
Outfall 007 discharges on episodic bases either non - contact cooling water as dictated by
maintenance or filtered river water overflow from sand filters. The filtered river water is the
source for the facility non - contact cooling water demand. The backwash from these filters is
collected in ponds and then recycled, no wastewater is discharged from the ponds. In recent
years no discharge was reported. There is no treatment process associated with this outfall
wastewater.
The facility has additional stormwater discharges covered under another permit.
HISTORY
The original permit included another outfall which was plugged and then removed from the
permit in 1995. Also, several changes in the discharge flows and stream classification have
occurred since the initial 1974 permit. Over the life of this permit various pollutants of concern
were monitored and evaluated. In December 2010 the receiving stream was re- classed from C+
to C, HQW and has no impact on this permit renewal. Any future expansion could be impacted.
Several permit modifications have occurred including an ownership change in 1997 to the
current owner. The Division reviewed and granted modification requests for (1) changing the
required toxicity test from acute to chronic in 1997, and for (2) removing dimethylformamide

monitoring ,and reducing the monitoring frequency for total aluminum and butlyrolactone in
1998.
The 2006 permit renewal included removal of monitoring for total aluminum and butlyrolactone,
and the addition of a conditional total residual chlorine limit with a June 2008 effective date for
outfalls 001, 003, and 007. To date no chlorine or chlorine derivatives have been applied.
COMPLIANCE
This facility had a history of not consistently meeting frequency monitoring requirements
resulting in some data not being reported. The non - submittal of quarterly TTQ data and/or the
alternate certification statement is another issue. The regional office has issued NOW in
response to these monitoring violations. There has been no limit violations or fines assessed
during the current permit cycle. The region recommends renewal of this permit.
PERMITTING STRATEGY
Reasonable Potential Analysis (RPA)
The Division conducted EPA - recommended analyses to determine the reasonable potential for
toxicants to be discharged by this facility from Outfall 001, based on DMR data from January
2009 to December 2010 and from the 1 PPA submitted with the renewal application. Evaluations
were conducted for copper, phenols, and zinc.
Results suggest no reasonable potential for the facility to discharge copper, phenols, and zinc.
As per guidelines, no monitoring is required so copper and zinc monitoring will be removed, but
will be reviewed in the next PPA.
The application listed ethylene glycol and gammabutralactone as process chemicals that may be
present in trace amounts in the discharge, primarily from spills, leaks, etc.. Ethylene glycol is a
non - carcinogen toxicant with a listed human health water quality standard of 2500 mg/L.
Currently, there is no applicable gammabutralactone water quality standard. No action required
in permit at this time.
Data review
DMRs were reviewed for the period of January 2009 to December 2010. DMR data is
summarized below in Table I for Outfall 001 and in Table II for Outfall 006:

No discharges occurred from outfall 007.
Outfall 001
Will amend TRC footnote to remove compliance date and add measurement protocol.
The daily discharge of intermittent deionization backwash wastewater is part of the effluent.
Based on the low IWC, 0.06 %, contributed by the deionization backwash and history of no
chronic toxicity failures, used best professional judgment and determined that no changes were
warranted.
Based on the episodic addition of process wastewater in Outfall 001 and its unknown impact to
the effluent characteristics, an episodic acute toxicity test will be incorporated in this permit. It
will be initiated upon the addition of process wastewater with a maximum test frequency not to
exceed more than one test per calendar month. The results will be used to evaluate future permit
conditions. A special condition will be added for notification to the Winston Salem Regional
Office when process wastewater is discharged.
Reporting of the required TTO documentation has been an issue, will include a discussion in the
cover letter to stress compliance.
Outfall 003
Will amend TRC footnote to remove compliance date and add measurement protocol.
Outfall 006
Will add conditional TRC monitoring, daily limit, and footnote narrative.
Outfall 007
Will amend TRC footnote to remove compliance date and add measurement protocol. Will
replace settleable solids parameter with TSS parameter.
Whole Effluent Toxicity
The permit requires quarterly chronic toxicity testing using ceriodaphnia dubia, at 0.75%
effluent concentration for Outfall 001. The facility passed its last 14 toxicity tests submitted
since January 2007. Will updated special condition narrative.
Instream Data Impact
Outfalls 001, 003, and 007 have both a maximum effluent temperature limit and a maximum
receiving stream temperature impact limit. Temperature was measured at designated points
upstream and downstream of outfall 001 only, as it was the only discharge that occurred. No
temperature violations occurred.
SUMMARY OF CHANGES
In keeping with Division policies the following will be incorporated into the permit:
• Outfall 001: Copper and zinc monitoring will be removed.
• Outfall 001: Episodic acute toxicity testing will be added and initiated by the episodic
addition of process wastewater.
• Outfall 001: TRC footnote will be amended.
• Outfall 003: Conditional TRC monitoring with daily limit and footnote narrative will
be added.

Mr. Narita,
After review of United Chemi -Con, Inc. NPDES renewal application, we need additional information
and /or clarity before we can proceed with this renewal.
Note: Answers and info provided by Butch Howell
1) In the 2006 NPDES renewal application that had been submitted a flow schematic with water
balance for each outfall was attached. We need an updated copy with labeled arrows indicating
the chemical name additives, biocides, antiscalants, cleaning compounds, etc., and where in the
flow schematic these chemicals are added that become part of the waste water being discharged.
An updated flow schematic is attached for reference. As we discussed earlier, the only chemicals
added to our wastewater are boiler chemicals and all of that flow is
directed to outfall WL
2) On the same flow schematic please indicate the location of flow meters and composite samplers,
and provide a description of the type off low meter including whether it has recording capability.
Completed. See attached.
3) On application item #12, the discharges need to be broken down further by outfall In some cases
the same type waste water may go to multiple outfalls so he may be listed more than once.
See attached.
4) Please provide a process description for "Ritered Surface Water", what is the filter media?
What is the source of waste water? Ritered surface water is water that has been processed
through our conventional gravity flow water filtration plant:
The media is rock/sand. No chemicals are added in this process.
5) Does stormwater discharge from any outfall?
stormwater Is discharged from outfall 001 and outfall 003. Other stormwater is discharged through
outfalls identified in permit(s) other than NPDES.
6) Is there any holding ponds retention lagoons on site? If yes, what is there purpose?
There are two holding/retention ponds. They are used to contain backwash water from the water
filter plant, and this discharge Is recirculated through the water filtration plant. No NPDES
discharge(s) are associated with these ponds.
7) How do you handle solid removal? You need to provide a short 2 -3 sentence narrative stoting
how you dispose of solids from you waste treatment process.
All solids are removed by commercial septage haulers.

Permit NCO042277
A. (2) CHRONIC TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct auarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1,998, or subsequent
versions. J
The effluent concentration defined as treatment two in the procedure document t90 %. The testing
shall be performed as a Ceriodaphnia dubia 7day.pass /fail test. The tests will b rformed during the
months of February, May, August, and November. Effluent sampling for this t ting shall be performed

Dechlorination Is not necessary ...... 000 does not have an effluent bacterial limit, hence no chlorine is
added.
9) On a scaled plot plan please indicate where the upstream and downstream sample points are in
relationship to the outfalls.
See attached.
10) On application item N17, indicate which outfalls have the potential to have these chemicals in
their waste stream.
Ethylene Glycol and Gammabutralactone have the potential to be discharged from outfall 001 only.
