Dear Mr. Lenderman:
A letter of request for an Authorization to Construct was received December 29, 1993 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 pumping station and outfall
relocation sewer line consisting of- (1) a pumping station with dual pumps rated at 185 gpm each with high
water alarm and on/off switching; (2) a liquid injection chlorinator system which injects the chlorine
directly into the effluent line as it leaves the pumping station --this system allows for approximately 74
minutes contact time with one pump running and 37 minutes contact time with both running; and (3)
approximately 9300 feet of 6 inch PVC pipe, and all necessary pumps, piping and appurtenances with
discharge of treated wastewater into an unnamed tributary to Mulberry Creek in the Yadkin/Pee-Dee River
Basin. Piping laid on steeper slopes must be anchored.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO046418 issued February 28, 1994, and shall be subject to revocation unless the
wastewater treatment facilities are constructed in accordance with the conditions and limitatiohs specified in
Permit No. NC0046418.
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

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, 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.
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
