Dear Mr. Bonn6:
In accordance with your permit modification application received January 9, 2008 and additional
information received January 24, 2008, we are forwarding herewith Permit Number WQ0018489, dated
January 31, 2008, to the Town of Cary for the continued operation of the subject wastewater treatment,
reclaimed water utilization system and bulk fill operation. With this modification, the Town is permitted
to supply reclaimed water to public restroom building at 161 Middle Creels Park Avenue.
In addition the following changes were made to the permit:
• Fire Fighting and fire extinguishing was modified as an allowable use of reclaimed water at the
bulk fill station to include a condition that Public Water Supply requirements must be met prior to
use. Public Water Supply requirements prohibit fire trucks from using non -potable water due to
the possibility of cross connection with other potable water systems, including building sprinkler
systems, without proper backflow prevention.
• Condition I.1 has been added to document that plumbing code has been met prior to opening of
the public restroom building at 161 Middle Creek Park Avenue.
Condition V.2 was modified to include a limitation on the inspection frequency required for high
volume bulk reclaimed water fill station users.
This permit shall be effective from the date of issuance until June 30, 2010; shall void Permit No.
WQ0018489 issued January 17, 2008 and shall be subject to the conditions and limitations as specified
therein.
Please pay particular attention to the monitoring requirements in this permit. Failure to establish an
adequate system for collecting and maintaining the required operational information will result in future
compliance problems.
