Dear Mr. Knowles:

This is to inform you that a review of your toxicity self -monitoring report forms for July 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, isolating the sources of toxicity, evaluating the
effectiveness of toxicity control options, and confirming 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 the appropriate mailing addresses for submitting your Discharge
Monitoring Reports (DMRs) and Aquatic Toxicity (AT) Test Forms. Also, the Aquatic Toxicology Branch now accepts
AT forms via email ([e-mail]); if an AT form is submitted via email, we do not require that a hard
copy is mailed. 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. Hannah Headrick at (919) 743- 8439.
