Mecklenburg County
The aquatic toxicity test using 24-Dour flow proportional composite samples of effluent discharged from
Clariant Corp. -Mt. Holly Plant has been completed. Clariant Corp. -Mt. Holly Plant has an effluent
discharge permitted that is 3.9 million gallons per day (MGD) entering the Catawba River (7Q10 of 329
CFS). Whale effluent samples were collected oil November 16 by iohn Lesley and a facility representative
and November 19 by Jahn Lesley and Dwayne Wallace (facility representative) for use in a chronic
C'eriodaphnia clubis pass -fail toxicity test. The test using these samples resulted in a pass. Toxicity test
information follows.
Test Type 3-Brood CerAiodaphnia dubia chronic pass fail
Test Concentrations L8%
Test Result Pass
Control Survival 92%
Control Mean Reproduction 17.0 neonates
Test Treatment Survival 100%
Treatment Mean Reproduction 22.5 neonates
First Sample pH T92 Sll
First Sample Conductivity 5.54 tnS/can
First Sample Total Residual Chlorine 0.28 mg/I}
Second Sample pH 7.77 SlT
Second Sample Conductivity 5.7 mS/cm
Second Sample Total Residual Chlorine <0.10 mg/1
Test results for the above samples indicate that the effluent would not be predicted to have water quality
impacts on receiving water. Please contact us if further effluent toxicity monitoring is desired. We may be
reached at (919) 743-401.

Dear Mr. Golder:
This is to inform you that a review of your toxicity self -monitoring report form for the month of
February 2104 indicates a violation of the toxicity limitation specified in your NPDES Permit.
You should take whatever remedial actions are necessary to eliminate the conditions causing the
effluent toxicity violations. Your efforts may include conducting a Toxicity Reduction` Evaluation
(T ) which is a site -specific 4study designed to identify the causative agents of effluent toxicity, isolate
the sources of toxicity, evaluate the effectiveness of toxicity control options, and then confirm reductions
in effluent toxicity. Please be aware that. North Carolina General Statutes provide for assessment of civil
penalties for violations of DES permit limitations and requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent
Toxicity Monitoring and Reporting Requirements. Please vacate updated mailing ad r ss s for submitting
your Discharge Monitoring Reports (DMRs) and Aquatic Toxicity (AT) Test Forms. We encourage you
to review this information and if it would be helpful to discuss this situation or passible solutions to
resolve effluent toxicity noncompliance, please contact Mr. John Lesley with this office at (704)',663-

Toxicity test condition language contained in your NPDES permit may require use of multiple concentration
toxicity testing upon failure of any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic
value is lower than'the permit limit, then at least two multiple concentration toxicity tests (one per month) will
be conducted over the following two months. As many analyses as can be completed will be accepted. If your
NPDES pernfit does not require use of multiple concentration toxicity testing upon failure of any single
quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration
toxicity testing per the Division's WET enforcement initiatives effective July 1, 1999. Follow-up multiple
concentration toxicity testing will influence the Division's enforcement response.
Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic
toxicity monitoring requirements (eg, if the testing months specified in your NPDES permit are March, June,
September, and December, then toxicity testing must be conducted during these months).
>
If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-
June 30, then you must provide written notification to the Environmental Sciences Branch by June 30 that a
discharge did not occur during the first six months of the calendar year.
If you receive notification from your contract laboratory that a test was invalidated, you should immediately
notify. -the Environmental Sciences Branch at [phone] and provide written documentation indicating why
the test was invalidated and the date when follow-up testing will occur.

complete the information block located at the top of the AT form indicating the facility name, permit number,
pipe number, county and the month/year of the subject report. You should also write "No Flow" on the AT
form, sign the form and submit following normal procedures,

for facilities which have not received a facility classification. In these cases, a duly authorized facility
representative must sign the AT form. The AT forn must also be signed by the performing lab supervisor.
