Authorization to Construct
W WTP / Harbour Estates
Mecklenburg County
Dear Mr. Colson:
A letter of request for an Authorization to Construct was received March 29, 1996 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 0.0416 MGD extended aeration package plant
consisting of an influent flow equalization tank with bar screen, a flow splitter box, two aeration basins, a
clarifier, a chlorine contact chamber and a sludge holding tank, with final discharge of treated wastewater
into the Catawba River (Lake Wylie) in the Catawba River Basin.
Due to noise complaints associated with the existing wastewater treatment facilities, measures
should be taken to ensure noise from the blowers or any other treatment unit be minimized to the extent
possible. It is the Division's recommendation that the newly constructed wastewater treatment facilities be
no closer than two hundred feet from any existing or future dwellings.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NC0063860, scheduled to issue July 29, 1996, and shall be subject to revocation unless the
wastewater treatment facilities are constructed in accordance with the conditions and limitations specified in
Permit No. NC0063860.
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 in -place 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 has been installed in
accordance with the NPDES Permit, this Authorization to Construct and the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC

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 Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II,111, and IV facility at least daily, excluding weekends and holidays, and
must properly manage and document daily operation and maintenance of the facility and must comply with
all other conditions of Title 15A, Chapter 8A, .0202. Once the facility is classified, the Permittee must
submit a letter to the Certification Commission which designates the operator in responsible charge within
thirty days after the wastewater treatment facilities are 50% complete.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the
life of the facility.

Permittee to an enforcement action by the Division of Water Quality in accordance with North Carolina
