This correspondence serves to notify the NC DWQ of our choice of options regarding the
toxicity NOV from October 2009. We have decided to conduct Toxicity Identification
Evaluations (TIE's) to provide results that definitively rule out Copper/Zinc as a cause of
effluent toxicity (option #3). It is our understanding that we have nine (9) months to
submit documentation that eliminates Copper and Zinc as causative effluent toxicants.
The fmal report will be submitted by September 28, 2010.
If you have any questions or require more information concerning this correspondence,
please contact me at your convenience.
Sincerely,
J. Brant Sikes, Superintendent
Moore County Water Pollution Control Plant
