Authorization to Construct
Paw Creek Terminal
Mecklenburg County
Dear Mr. Harvin:
A letter of request for an Authorization to Construct was received June 17, 1996 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 tertiary treatment system, to be used in
conjunction with the currently operational groundwater remediation facility, consisting of two particulate
filters and two 200 pound granular activated carbon units arranged in series with discharge of treated
wastewater into an unnamed tributary of Long Creek.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO004839 issued December 13, 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. NC0004839.
Any 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 Water Quality.
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.
Alternate disinfection methods may be required to be constructed should ultraviolet disinfection prove to be
unreliable. Utilization of chlorine for disinfection will require addition of dechlorination facilities or
process changes to insure removal of residual chlorine before discharge of wastewater to the environment.
The Mooresville 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
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 11, 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.
The Operational Agreement between the Permittee and the Environmental Management
Commission is incorporated herein by reference and is a condition of this Permit. Noncompliance with the
terms of the Operational Agreement shall subject the Permittee to all sanctions provided by G. S. 143-
215.E for violation of or failure to act in accordance with the terms and conditions of this Permit.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Water Quality 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. Mark McIntire, telephone number(919) 733-
5083, extension 553.
Sincerely,
Preston Howard, Jr., P.E.
