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, guarteriz{ 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-Februaryi1998) 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 n 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:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Environmental Sciences Branch 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.
Should any test data from this monitoring requirement or tests performed by the North
Carolina Division of Water Quality 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.

Permit NC0000019
A.(6.) BIOCIDE CONDITION
The permittee shall not use any biocides except those approved in conjunction with the permit
application.- The permittee shall notify the Director in writing not later than ninety (90) days prior to
instituting use of any additional biocide used in cooling systems which may be toxic to aquatic life
other than those previously reported to the Division of Water Quality. Such notification shall include
completion of Biocide Worksheet Form 101 and a map locating the discharge point and receiving
stream.
R9 .,
A.(7.) DISINFECTION CONDITION
In the event that violations of the fecal coliform requirements of the North Carolina water quality
standards occur as a result of this discharge, disinfection will immediately be required and the
permit amended to establish a coliform effluent limitation.

NPDES # NC0000019
United Chemi-Con
Lansing, NC 28643
Present Operating Status
Outfall 001 — Effluent from outfall 001 is comprised of non -contact cooling water
generated from cooling air compressors and air dryers. Air conditioner condensate,
boiler blowdown and deionizer backwash, assembled product wash water and process
wastewater are typically not discharged except under rare occasion. Rainwater from the
facility roof is included in this discharge. There are no treatment facilities associated
with this outfall.
Outfall 003 — Effluent from this outfall is intermittent and consists entirely of air
conditioner condensate and rain water runoff from atop the manufacturing facility. There
are no treatment facilities associated with this outfall.
Outfall 006 — This discharge is from the treatment of domestic wastewater generated
from an Imhoff cone treatment process followed by sand filter treatment. This process
treats domestic type waste only and flows are entirely dependent upon the frequency,
duration, and number of employees present at the facility. Influent wastewater is
collected and introduced into the wastewater treatment plant by first passing a manual bar
screening device. The screened wastewater then flows into the Imhoff cone for solids
separation and anerobic digestion. The Imhoff cone has a capacity of 15,633 gallons with
an average detention time of 15.6 days. After treatment in the Imhoff cone, wastewater
flows into the dosing chamber for holding until being applied to either of two sand filters.
The dosing chamber detention time is approximately one day. The sand filters are 2,312
square feet each and have a hydraulic loading of approximately 2 gallons/square feet per
day. The effluent from the sand filter(s) are then discharged to the receiving stream via a
parshall flume flow measuring device.
Outfall 007 — This discharge is comprised of non -contact cooling water and filtered
surface water during routine maintenance periods only. There are no treatment facilities
associated with this outfall.

UNITED
CHEMI-CON
United Chemi-Con Sludge Management Plan
All sludge generated during treatment of domestic waste at United Chemi-Con is
disposed by commercial septic haulers, and does not involve on site treatment or
monitoring. No industrial type waste is treated by this facility.

Summary Notes
NC0000019
-page 2
A review of the effluent data for the recommended parameters indicates that both DMF
and Butyrolactone have been less than detection for the past two years. However, the lab
has used different detection levels (<5, <10, QO and <25) for Butyrolactone. Win
concur with facility request for reduction in monitoring to quarterly for
Butyrolactone.
Aluminum had detectable levels through 1996 until the start of 1997. Will not do away
with all monitoring. Will concur with facility request for reduction in monitoring to
quarterly for aluminum.
Since DMF has been not detectable for two years and letter indicates that it is no
longer used in the process, will concur with deletion of monitoring requirement.

6 Monitoring requirements apply if chlorine is added to the cooling water (or any other wastewater contributor).
There shall be no chromium, zinc or copper added to the treatment system except as pre -approved additives to biocidal
compounds (see Part III, Condition F - Biocide Condition).
The pH shall not be less than 6.0 standard units nor" greater than 9.0 standard units and shall be monitored weekly at the
effluent by grab sample.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Part III Permit No. NC0000019
E. CHRONIC TOXICITY PASSNAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 0.75% (defined as treatment two in the procedure document). The permit holder shall perform
quarterly monitoring using this procedure to establish compliance with the permit condition. The tests will be
performed during the months of January, April, July & October. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 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,

E. CHRONIC TOXICITY PASSNAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 0.75% (defined as treatment two in the procedure document). The permit holder shall perform
quarterly monitoring using this procedure to establish compliance with the permit condition. The tests will be
performed during the months of January, April, July & October. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water Quality

Raleigh, North Carolina 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 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 Environmental Sciences
Branch at the address cited above.
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 passing, this monthly test requirement
will revert to quarterly in the months specified above.
