Dear Mr. Benton:
A letter of request for an Authorization to Construct was received September 30, 1992 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 filter backwash and alum sludge
settling decant wastewater treatment system consisting of clarifiers, sludge thickeners, belt filter presses,
sludge drying/storage beds, and two raw water pretreatment lagoons (which receive raw water as well as
filter backwash and sludge decant), each with discharge of treated wastewater into an unnamed tributary to
the Neuse River (via outfall 001) and Honeycutt Creek (via outfall 002).
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO082376 issued March 12, 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.
NC0082376.
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 Raleigh 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

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

PART III - EVALUATION AND RECOMMENDATIONS
The City of Raleigh must reduce the amounts of manganese,
trihalomethanes.and solids in its final drinking water. In order
to do this they propose to improve solids handling/ treatment and
to discharge from the pretreatment lagoons intermittently as
required.
The proposed additions to the solids handling process
should improve drinking water quality and effluent quality. The
RRO recommends the A to C be issued once the NPDES permit is
issued..
