Authorization to Construct
City of Wilson
Hominy Creek WWMF

Project No. CS 370381-06
A letter of request for Authorization to Construct was received October 15, 2003, 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 modifications to the
existing 14 MGD Hominy Creek Wastewater Management Facility, with discharge of treated
wastewater into Contentnea Creek in the Neuse River Basin.
This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following specific modifications:
One additional 780,000 gallon aeration tank, the upgrade of four existing anaerobic
digesters, construction of a new sludge thickening and dewatering building, with two new
gravity belt thickeners, two belt filter presses, a new waste activated sludge pump station
with three 900 gpm pumps, a new ten ton per day alkaline sludge stabilization facility,
three new 50,000 gallon sludge holding tanks, a new septage receiving station,
replacement of the existing primary sludge pumping system, a new drain pump station,
and a new 4,633 square foot administration/laboratory building.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0023906 issued November 1, 2001, and shall be subject to revocation
unless the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in Permit No. NC0023906.
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.
