Authorization to Construct
ATC No. 026051ACD
Triangle WWTP
Durham County
Dear Mr. Hill:
On November 19, 1998, the Division of Water Quality received your request for
Authorization to Construct (ATC) in accordance with NPDES Permit Number NC0026051. The
plans and specifications for constructing a bypass around the mechanical bar screens at the
influent pump station have been reviewed and it was determined that they are satisfactory.
Authorization is hereby granted for the construction of the subject bypass line. The enclosed
copy of the approved plans and specifications must be maintained on file for the life of the
facility.
Although this Authorization to Construct request has been granted, the Division is not
confident that this bypass line will solve all of the problems that are plaguing the influent pump
station and causing the illegal discharges. The Division requests that you investigate the
possibility of upgrading the influent pump station or develop alternative plans to reduce the
potential for future illegal discharges.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0026051 issued March 4, 1996, and shall be subject to revocation unless
the proposed bypass line is constructed in accordance with the conditions and limitations
specified in Permit No. NC0026051.
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.

complying with any and all statutes, rules, regulations, or ordinances which may be imposed by
