Dear Mr. Culbreth: •
A letter of request for a new Non-Discharge Permit and Authorization to Construct for a new
combined NPDES and Non-Discharge treatment facility replacing the existing permitted 0.04 MGD
NPDES treatment facility was received January 8, 2015, by the Division of Water Resources
(Division) Non-Discharge Permitting Unit. The NPDES design capacity will remain at 0.04 MGD.
Final revised plans and specifications for the subject treatment facility project have been reviewed by
the NPDES Permitting Unit and found to be satisfactory for meeting NPDES permit requirements.
Additional Non-Discharge treatment criterion and other construction approvals will be addressed in the
issued Non-Discharge Permit. Authorization is hereby granted for the construction of modification to
the existing Trillium Links & Village WWTP, with discharge of treated wastewater into the unnamed
tributary into Hurricane Creek in the Little Tennessee River Basin.
This authorization results in no increase in design or permitted capacity and is awarded for the
construction of the following specific modifications:
Demolition of existing bar screen system and replacement with new 2 mm opening
mechanical bar screen system rated for 175 GPM, piping, and controls; refurbishment of
existing EQ/sludge holding/splitter box tank to new EQ tank system (one new section 7,500
gallons, one new section 21,300 gallons) with new drop down diffusers, piping, and
controls; installation of two (2) new 83 GPM at 22.5 ft TDH self-priming /self-cleaning
centrifugal EQ pumps, piping, and controls; demolition of existing clarifiers, filters, post
aeration chambers, chlorine contact chamber, tablet chlorinator, and tablet de-chlorinator;
repurposing/refurbishment of one (1) extended aeration tanks to install a 6,670 gallon Stage
1 Anoxic chamber with new submerged mixer, a 6,500 gallon Oxic chamber with new air
diffusers and new submerged 460 GPM at 9.5 ft TDH recycle pump, a 5,630 gallon Stage
2 Anoxic chamber with new submerged mixer and new submerged 515 GPM at 7.5 ft TDH
