Waxhaw Professional Center
Flow Reduction Approval
Union County
Dear Ms. Putnam:
On November 22, 2007, the Division of Water Quality received a flow reduction request for
the expansion of the Waxhaw Professional Center served by the Union County WWTP (Permit No.
NC0085359). The letter requests an allowable flow rate of 2,212 GPD for the facility based on the
water use data from the facility.
The water use data provided between November 2005 and November 2006 was analyzed by
central office staff. Based upon this data the Division hereby approves a reduction in flow to 3,100
gallons per day for subject facility based on a maximum of 20 physicians.
Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater
flows exceed the effluent limits defined in the NPDES permit for the treatment facility or exceed the
capacity of the sewers downstream of any new sewer extension or service connection(s).
If you have any questions or comments regarding this matter, please contact Deborah Gore at
[phone] ext. 593, email [[e-mail]].
Sincerely,
Coleen H. Sullins
