Dear Mr. Masters:
A letter of request for an Authorization to Construct was received August 1, 1995 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 continued operation of a 0.0125 MGD wastewater treatment facility
consisting of an existing package treatment plant with aeration chamber, sludge holding tank and clarifier,
and the construction of a 33 by 33 foot recirculating sandfilter with surface laterals, 5:1 flow splitter, 1500
gallon recirculation tank with air diffuser, filter screens and dual pumps, tablet chlorinator, tablet
dechlorinator and remove from service the existing polishing pond with discharge of treated wastewater
into an unnamed tributary to Flat Swamp Creek./
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NC0023604 issued August 19, 1993, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in Permit No.
NC0023604.
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 Environmental Management.
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, 910/771-4600 telephone number, 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 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, 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 of Title 15A, Chapter 8A, .0202.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the
life of the facility.
The sand media of the sandfilter must comply with the Division's sand specifications. The
engineer's certification will be evidence that this certification has been met.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Environmental Management 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.
One (1) set of approved plans and specifications is being forwarded to you. If you have any
questions or need additional information, please contact Mr. Charles Alvarez, telephone number 919/733-

PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
(PROVIDE THE FOLLOWING INFORMATION IF IT IS NOT ON THE PREVIOUS NPDES
STAFF REPORT)
1. Existing treatment facility:
a. What is the current permitted capacity of the facility?
-0125 MGD
b. Date(s) and construction activities allowed by previous Authorizations to
Construct issued in the previous two (2) years: None
c: What is the actual treatment capacity of the current facility (design volume)?
.0125 MGD
d. Please provide a description of existing or substantially constructed wastewater
treatment facilities. The existing facility is a 0.0125 MGD package treatment
plant, consisting of an aeration basin, clarifier, sludge holding tank, and chlorine
contact chamber. The effluent from the package plant is routed to a fifty-four
day polishing pond before being discharged down a cascade aerator.
2. Please provide a description of proposed wastewater treatment facilities: The facility is
proposed to be up -graded with a recirculating sandfilter which would allow it to meet the
ammonia limits in the permit. The polishing pond currently allows the facility to meet
the ammonia limit, but algae in the pond is believed to be responsible for the facility's
inability to consistently meet BOD and TSS limits. With the installation of the sandfilter,
the pond will be abandoned as a treatment component.
3. Residuals handling and utilization/disposal scheme: Sludge is pumped as needed, and
disposed of in a POTW.
a. If residuals are being land applied, please specify DEM permit no.
Residual Contractor:
Telephone No.
b. Residuals stabilization: PSRP _ PFRP Other
c. Landfill:
d. Other disposal/utilization scheme (Specify):

PART III - EVALUATION AND RECOMMENDATIONS
This A to C was applied for in conjunction with a proposed S.O.C. The permittee has
extensively investigated non -discharge options, but none panned out.
The Region recommends that, upon satisfactory completion of the engineering review,
the A. to C. be issued.
