PART III - EVALUATION AND RECOMMENDATIONS
The utility wastewater that makes up the discharge for Outfall 002 are the fire tank tower
"blowdown", RO reject and cooling tower blowdown. The fire tank tower source water
is river water from Livingston Creek. The discharge from the fire tank tower should not
be comingled ahead of the sampling oint for the RO reject and cooling tower blowdown
as it serves to elute the two other waste streams. Either the discharge form the fire tower
should be diverted below the sample collection point for the two other wastewater
sources, or monitoring for the RO reject and cooling tower will need to be conducted
upstream of the point where the fire tank tower water is being comingled. For an
understanding of the history of this facility, please refer to the permit renewal staff report
on file, dated October 16, 2006.
The region is in support of renewal provided the permit is issued with consideration
to the concerns provided herein, is issued in accordance with the Cape Fear River

Basinwide Plan, and no adverse public comments are received concerning this
renewal.. Thank you for the opportunity to comment.
