Dear Mr. Wallwork:
A letter of request for an Authorization to Construct was received July 12, 1990 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 a 205,000 gallon sludge
digestion tank, the utilization of the existing concrete basin (approved for sludge digestion in the
Authorization to Construct issued December 15, 1989) as part of the flow retention system, the
removal of the existing retention tank when inspection indicates the need, and any piping changes
necessary to place these facilities in operation. These facilities are to be constructed as additions to
or alterations of the facilities permitted in the Authorization to Construct issued December 15, 1989
only as stated herein. All previously facilities not specifically addressed herein are to remain as
previously permitted.
This Authorization to Construct is issued in accordance with Part III paragraph B of
NPDES Permit No. NCO003573 issued March 13, 1987, and shall be subject to revocation unless
the wastewater treatment facilities are constructed in accordance with the conditions and limitations
specified in Permit No. NC0003573.
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 Environmental
Management.
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.
