Re: Cambridge Park Phase lA Permit Modification for WQ0040466
Dear Justin:
Enclosed you will find a Fast-Track Sewer Application package for a proposed
subdivision in the City of Mebane for your review. This is a modification to Permit
#WQ0040466, this original permit had-0- flow allocated and this modification now
accounts for 18,480GPD of flow. Items included in this package consists of; check for
$480, FTA 04-16, FTSE 01-16, Flow Tracking/acceptance, approved permit WQ0040466
and USGS Map. This project is called Cambridge Park Phase IA, located on Jones Drive
in Mebane,NC. This phase consists of 65 single family lots for sale and is the first phase
of a larger subdivision. This project is served by an onsite gravity sewer system flowing
to a proposed pump station(design/processing by others)than ultimately tying on to an
existing City of Mebane sewer system. Feel free to contact me with any questions or
comments.
Sincerely,
Dave Southard

Subject; Mebane WWTP (NC0021474)
Flow Reduction Request
Alamance County
Dear Mr, Wilson:
On February 14, 2011, the Pretreatment, Emergency Response and Collection System (PERCS) Unit of
the Division of Water Quality received a flow reduction request for connections to the City of Mebane WWTP.
The letter requests on allowable flow rate of 80 gallons per day(gpd)per bedroom based on the evaluated data.
As daily WWTP data is not representative of the project area, the DMR data from the City of Mebane
W WTP (NC0021474)from January 2009 through December 2009 was evaluated to determine the peak sewage
month. The highest flow month was December 2009. Daily wastewater flows were recorded downstream of
the Holly Ridge Subdivision during December 2010, This data was reviewed by PERCS and Regional Office
staff,
Eased on the data, the Division hereby grants a reduction in flow to 80 gpd/bedroom (minimum of 160
gpd for 1 and 2 bedroom residences) for sewer extension permits issued tributary to the City of Mebane
WWTP'
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 capacit of
sewers downstream of any new sewer extension or service eonnection(s).
If you have any questions or comments regarding this matter, please contact Sarah Morrison at (919)
807-6310, or email [[e-mail]] or Deborah Gore, Unit Supervisor at [phone], or
email [[e-mail]].
Sincerely,
