NPDES Permit NC0036196
Catawba County
Dear Mr. Wilson:
A request for an Authorization to Construct (ATC) was received by the Division February 4,
2004, and final plans and specifications for this project have been reviewed and found to be
satisfactory. Authorization is hereby granted for the improvements to the City of Newton's
Wastewater Treatment Plant (WWTP). The majority of the permit authorizes the
renovation/refurbishment of existing treatment units. In general, this ATC allows:
• The replacement of screening/conveying at the influent pump station,
• The replacement of internal equipment in the reactor (primary) clarifiers,
• The replacement of internal equipment in secondary clarifiers no. 1 and 2,
• The renovation of the effluent filters and control system,
• The replacement of the existing chlorine system and the addition of dual feed SO2
dechlorination (retaining the same chlorine detention time),
• The installation of septage storage tank/receiving station,
• The replacement of lime slurry tanks,
• The installation of thickener mechanisms/equipment in place of the existing sludge storage
tanks,
• and all additional piping, and appurtenances.
Once construction under this ATC has been completed and an Engineer's Certificate has been
submitted, the permittee is authorized to operate the units listed above, with permitted limits as
specified in the 1VPDES permit issued December 6, 2002. This Authorization to Construct permit
does not modify the existing design low of 5.0 MGD for the Newton WWTP. The Division of Water
Quality approves this project in terms of compliance with NPDES limits; we defer to the City of
Newton and their consultants for approval of structural integrity, etc. of the various treatment
units, as well as compliance with any other required programs.
This Authorization to Construct is issued in accordance with NPDES Permit No.
NC0036196 issued December 6, 2002, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in
the permit.
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.

at least weekly and each Class II, III, 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 outlined in Title 15A, Chapter 8G, .0204. Once the
facility is classified, the Permittee must submit a letter to the Certification Commission which
designates the operator in responsible charge within: (A) Sixty calendar days prior to wastewater
being introduced into a new system or (B) within 120 calendar days of the following, (i) after
receiving notification of a change in the classification of the system requiring the designation of a
new ORC and back-up ORC or (ii) a vacancy in the position of ORC or back-up ORC.

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.
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 NPDES Unit, Division of Water
Quality, 1617 Mail Service Center, Raleigh, NC 27699-1617.
