Dear Mr. Vandenberg:
The Division of Water Quality received the City of Laurinburg's request for an Authorization to
Construct on February 6, 1998. The Division has reviewed the final plans and specifications for
the subject project and found them to be satisfactory. The Division hereby grants authorization
for the following wastewater treatment improvements:
• construction of one (1) aerated grit removal system,
• removal of existing grit removal system; and
• construction of all associated structures, equipment, piping, valves, and all other
appurtenances as described in the plans and specifications.
Upon completion of these improvements and submittal of the Engineer's Certification (see
below), the approved treatment capacity of the subject facility remains at 4.0 MGD.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of the City's
NPDES Permit No. NC0020656 issued December 6, 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. NC0020656.
Upon completion of construction and prior to operation of the modified facility, the Permittee
shall provide the Division with a certification 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 NPDES Unit,
NCDENR, P.O. Box 29535, Raleigh, NC 27626-0535.
The existing Grit Removal Basin has experienced numerous overflows due to added flows from
inflow and infiltration (I/I). The Division strongly encourages the City to continue to reduce peak
flows to the facility through an I/I management program.
The sludge generated from this treatment facility 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.

The Permittee shall notify the Fayetteville Regional Office, telephone number 910-486-1541, at

sanctions provided by G. S. 143-215.6 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 life of the facility. One (1) copy of the approved plans and specifications is enclosed for your
