Dear Mr. Gobble:
The Division received a letter of request for an Authorization to Construct (ATC) April 27, 1998
and final plans and specifications for this project have been reviewed and found to be satisfactory.
Authorization is hereby granted for the construction of additional facilities at the existing 1.37 MGD
Louisburg wastewater treatment facility with outfall 001 discharging into the Tar River in the Tar-
Pamlico River Basin. Specifically, this ATC allows:
• installation of a 70 foot diameter, 25 foot deep aerobic digester with,
• three 15 HP submersible aerators
+ one floating aerator
• decant capability
• emergency overflow to the head of the plant
• conversion of the existing aerobic digester to sludge holding,
• installation of additional piping, valves, control equipment and appurtenances.
Since the ATC for the by-pass/overflow Iine for the tertiary filters was previously issued on
February 6, 1997 it is not included in this request.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO020231 issued March 1, 1995, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in the
permit.
The sludge generated from these treatment facilities must be disposed of in accordance with G.S.
143-215.1 and in a manner approved by the North Carolina Division of Water Quality.
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.
The Raleigh Regional Office, telephone number [phone], shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities so that an in-place inspection can be

the life of the facility.
