Project No. CS370431-04
Dear Mayor McLeod:
A letter of request for Authorization to Construct was received on December 29, 2003, by
the Division, and final plans and specifications for the subject project have been reviewed and
found to be satisfactory. Authorization for the construction of modifications to the existing 1.9
MGD Wastewater Treatment Plant, with discharge of treated wastewater into the Neuse River in
the Neuse River Basin was issued on October 4, 2004. We are re-issuing this Authorization to
Construct to correct the A to C number from 02543AOI to 025453A03. No conditions of this
Authorization to Construct are changed from previously issued Authorization to Construct
except the A to C Number. This A to C thus voids A to C No. 02543AOI issued on
October 4, 2004.
This authorization results in an increase in design and permitted capacity to 2.5 MGD,
and is awarded for the construction of the following specific modifications:
A new 214,500 gallon anaerobic basin; one new 300,000 gallon anoxic tank, one
new 200,000 gallon anoxic tank; modifications to the existing aeration basins; a
new 360,000 gallon sludge holding/digestion tank with two blowers each having
1100 SCFM of aeration capacity, and two10 HP submersible mixers,
instrumentation, site work, piping, electrical work, and associated appurtenances,
pursuant to the letter of request received on December 29, 2003, and 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. NCO025453 issued March 11, 2004, and shall be subject to revocation unless
the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in Permit No. NC0025453.
