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 Wilmington Regional Office, telephone number 910-395-3900, 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

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 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.
A leakage test shall be performed on the dosing tank to insure that any exfiltration occurs at a rate
which does not exceed twenty (20) gallons per twenty-four (24) hours per 1,000 gallons of tank capacity.
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.
