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 ofNPDES permit limitations and
requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring
