This is to inform you that a review of your toxicity self -monitoring report form for the month of March 2018 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 Mr. John Giorgino with this office at (919) 743- 8441.
