Dear Mr. Cummings:
A letter of request for Authorization to Construct was received April 29, 2005, 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 6.0 MGD Crowders Creek Wastewater Treatment Plant, with discharge of treated
wastewater into the Crowders Creek in the Catawba River Basin.
This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following specific modifications:
Rehabilitation of one exisiting digester with new fixed cover, installation of a sludge
mixer, associated piping and appurtenances; and piping modifications to the second
digester, 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. NC0074268 issued September 9, 2003, and shall be subject to revocation
unless the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in Permit No. NC0074268.
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.

wastewater treatment facilities. The operator must hold a certificate of the type and grade at
least equivalent to or greater than the classification assigned to the wastewater treatment
facilities by the Certification Commission.
The Permittee must also employ a certified back-up operator of the appropriate type and

continue to properly maintain and operate the existing wastewater treatment facilities at all times,
and in such a manner, as necessary to comply with the effluent limits specified in the NPDES
Permit.
You are reminded that it is mandatory for the project to be constructed in accordance
with the North Carolina Sedimentation Pollution Control Act, and, when applicable, the North
Carolina Dam Safety Act. In addition, the specifications must clearly state what the contractor's
responsibilities shall be in complying with these Acts.
Failure to abide by the requirements contained in this Authorization to Construct may
subject the Permittee to an enforcement action by the Division of Water Quality in accordance
with North Carolina General Statute 143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from
complying with any and all statutes, rules, regulations, or ordinances which may be imposed by
other government agencies (local, state, and federal) which have jurisdiction.
