Whole Effluent Toxicity (WET) Testing
NPDES Permit No. NCO086169/003
Fiber Optic Facility
Cabarrus County
Dear Mr. Novotny:
This is to inform you that a review of your toxicity self -monitoring report forms for January 2019 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
violation(s). Your efforts may include conducting a Toxicity Reduction Evaluation (TRE), a site -specific study
designed to identify the causative agents of effluent toxicity, isolate the sources of toxicity, evaluate the
effectiveness of toxicity control options, and confirm reductions in effluent toxicity. Please be aware that North
Carolina General Statutes provide for assessment of civil penalties for violations of NPDES permit limitations and
requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring
and Reporting Requirements. Please note appropriate mailing addresses for submitting your Discharge Monitoring
Reports (DMRs) and Aquatic Toxicity (AT) Test Forms. We encourage you to review this information; if it would be
helpful to discuss this situation or possible solutions to resolve effluent toxicity noncompliance, please contact Ms.
Cindy Moore at [phone] or Ms. Susan Meadows at (919) 743- 8439.
