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

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 permit 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.
