Dear Mr. Waters:
A letter of request for an Authorization to Construct was received January 3, 1994 by the Division
and final plans and specifications for the subject project have been reviewed and found to be satisfactory.
Authorization is hereby granted for the construction of improvements to the 2.12 MGD wastewater facility

not occur until an additional authorization to construct is issued for the outfall relocation. These
improvements include an additional grit removal chamber, a flow splitter box, a new mechanical bar screen
to supplement the existing mechanical bar screen, a new influent flow metering vault, a new 65 foot
diameter clarifier to supplement the two other identical clarifiers, return activated sludge pumps and all
piping, valves, electrical fixtures and appurtenances necessary to correctly operate these additions with
discharge of treated wastewater into Kennedy Creek and eventual discharge into the Pamlico River.
This Authorization to Construct is issued in accordance with Part III, Paragraph C of NPDES
Permit No. NC0020648 issued November 1, 1993, and shall be subject to revocation unless the

I43-215.1 and in a manner approved by the North Carolina Division of Environmental Management.

conditions, the Permittee shall take immediate corrective action, including
Division, such as the construction of additional or replacement Wastewater those
or diisposal facilities.
