Dear Mr. Cagle:
Coleen H. Sullins, Director

A fast track application for Authorization to Construct dechlorination facilities was
received on October 13, 2008, by the Division. Authorization is hereby granted for the
construction of modifications to the existing Long Creek WWTP, with discharge of backwash
effluent into Long 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:
Installation of a dechlorination system utilizing calcium thiosulfate pursuant to the
fast track application received on October 13, 2008, and in conformity with the
Minimum Design Criteria for Dechlorination Facilities.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0025879 issued October 30, 2007, and shall be subject to revocation
unless the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in Permit No. NC0025879.
In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as may
be required by this Division, such as the construction of additional or replacement wastewater
treatment or disposal facilities.
