Dear Mayor Biles:
A letter of request for Authorization to Construct was received on October 14, 2005, by
the Division to address modifications in the proposed design through memorandum of
negotiations. 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 4.0 MGD Eagle Road Wastewater Treatment Plant, with discharge of treated wastewater
into the South Fork of the Catawa River in the Catawa River Basin.
This authorization voids the authorization to construct (A to C No. 006033AO 1) issued on
May 13, 2005, and results in no increase in design or permitted capacity and is awarded for the
construction of the following specific modifications:
Upgrade of the existing Eagle Road WWTP with the addition of six 75-HP
aerators, two new 833 GPM RAS pumps, two new 1,390 GPM RAS pumps, two
new 150 GPM WAS pumps, modification of the existing chlorine contact
chamber including a dechlorination system and a diffused air post aeration system
with a 145 scfm blower, a new 800 KW stand-by generator, upgrades on two
existing 90 foot diameter clarifiers, a new 3,030 square foot laboratory building,
all associated site work, piping, and appurtenances.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0006033 issued January 26, 2002, and shall be subject to revocation
unless the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in Permit No. NC0006033.
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 Mooresville 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 on site
inspection can be made. Such notification to the regional supervisor shall be made during the
normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State
Holidays.
Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted facility

approved plans and specifications. Mail the Certification to Cecil G. Madden, Jr., P.E.,

Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of the
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
grade to comply with the conditions of T15A:8G.0202. The ORC of the facility must visit each
Class I facility at least weekly and each Class II, III and IV facility at least daily, excluding
weekends and holidays, must properly manage the facility, must document daily operation and
maintenance of the facility, and must comply with all other conditions of TI5A:8G.0202.
A copy of the approved plans and specifications shall be maintained on file by the
Permittee for the life of the facility.
During the construction of the proposed additions/modifications, the permittee shall
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.
