Dear Ms. McLelland:
A letter of request for Authorization to Construct was received August 4, 2005, by the

to be satisfactory. Authorization is hereby granted for the construction of modifications to the
existing 20 MGD Sugar Creek Wastewater Treatment Plant, with discharge of treated
wastewater into Little Sugar Creek in the Catawba River Basin.
This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following specific modifications:
Construction of an influent pump station with four low head pumps with 70 MGD
peak capacity, and seven high head pumps with 120 MGD peak capacity; four
mechanical bar screens with 200 MGD peak capacity and 1/2-inch clear space; a
130 MGD grit removal facility with dual vortex grit collectors, and dual 250 GPM
grit pumps; a 3000 CFM dry scrubber odor control system; a 20 MG flow
equalization basin, a 2,200 kW stand-by generator, associated piping, electrical
work, and site work in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of
Environment and Natural Resources.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0024937 issued April 29, 2005, and shall be subject to revocation unless

The Permittee must also employ a certified back-up operator of the appropriate type and
