Wastewater Treatment Facility
Catawba County
Dear Mr. Bumgarner,
A letter of request for an Authorization to Construct was received January 24, 1994 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 expansion to 0.030 MGD, including the construction of a septic tank
and gravity sewer for the proposed West Catawba Middle School,combiningthe resulting effluent with the
wastewater from the septic tank at the Fred T. Foard High School,applying the wastewater to existing
recirculating sandfilters located at the high school, and for the addition of dechlorination with discharge of
treated wastewater into Pott Creek.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NC0029297 issued July 29, 1994, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in Permit No.
NC0029297.
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 Mooresville Regional Office, telephone number 704/663-1699 , 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 professionalengineer 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. 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.
A leakage test shall be performed on the septic tank to insure that any exfiltration occurs at a rate
which does not exceed twenty (20) gallons per twenty-four (24) hour per 1,000 gallons of tank capacity.
The engineer's certification will serve as proof of compliance with this condition.
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 Charles Alvarez, telephone number 919/733-
5083.

nn January 28, 1994, this Office submitted a SR concerning
the connection of wastewater from a proposed West Catawba Middle
School into the subject school's existing WWTP. As a result of
our review, we could not support the proposed connection based on
projected flow figures providerd by the (:atawba County School
System's engineer. rnnsequently, a rernmmendation for denial of
the ATC was forwarded to the central Office.
subsequently,.. new information has been provided to this
Office that, if acc rate, would sup ort the proposed onnnec_tiOn.
T+t has been learnerilearned that t_he sand be_rl at Fred T.

to accommodate the wastewater flow from both srhnnls paced o'1 a
