Dear Mr. Carlton:
A letter of request for an Authorization to Construct was received March 21, 1997 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 additional wastewater treatment facilities with a design flow of 1.5 MGD consisting of a mechanical bar
screen capable of treating the entire treatment plant flow, a grit separator, an influent pump station, a flow splitter box, an
oxidation ditch with fine bubble diffusors, a secondary clarifier, sludge recirculation metering equipment,gas chlorination and
dechlorination,an aerobic sludge digester and a standby power generator with final discharge of treated effluent into
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES Permit No.
NCO020338 issued June 5, 1997, and shall be subject to revocation unless the wastewater treatment facilities are constructed
in accordance with the conditions and limitations specified in Permit No. NC0020338.
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 Winston-Salem 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 27626-0535.
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

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.
The Operational Agreement between the Permittee and the Environmental Management Commission is incorporated
herein by reference and is a condition of this Permit. Noncompliance with the terms of the Operational Agreement shall
subject the Permittee to all sanctions provided by G. S. 143-215.6 for violation of or failure to act in accordance with the
terms and conditions of this Permit.
Failure to abide by the requirements contained in this Authorization to Construct may subject the Permittee to an
