Division personnel have reviewed and approved your application for minor modification of the subject
permit. Accordingly we are forwarding the attached modified permit page. Please remove the existing
“Effluent Limitations and Monitoring Requirements” page and replace it with the one attached to this
letter.
Beverly Eaves Perdue
Governor
This modification is issued pursuant to the requirements of North Carolina General Statute 143-215.1
and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).

This modification reduces the effluent monitoring frequencies for Biochemical Oxygen Demand
(BOD5), Total Suspended Solids (TSS), Ammonia Nitrogen (NH3-N) and Fecal Coliform from daily
(5/week) to 2/week monitoring. The modification was based upon an evaluation of three years of
facility effluent monitoring data. The facility’s performance satisfies the criteria established in the
“DWQ Guidance Regarding the Reduction of Monitoring Frequencies in NPDES Permits for
Exceptionally Performing Facilities” as approved by the Director of the Division of Water Quality on
October 22, 2012, and justifies reduced monitoring for these parameters. The modified monitoring
frequencies will become effective on February 1, 2013.

require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other

Autumn,
As we discussed by phone this morning, the Triangle Wastewater Treatment Plant and Collection system weathered the
storm without any know spills. Prior to the storm we activated our IWERP (Inclement Weather Emergency Response
However to weather the storm, we did use almost all of our countermeasures, including:
Diverting peak influent flow to almost fill Train 3.
Filling and starting a third clarifier.
Running all UV at 100%.
Operating the pressure sewer pump stations at Scott King and Fairfield manually in a dual pump mode. To
maximize pumping rate, we alternated operation of each station.
Operating our largest pump station Stirrup Iron manually with peak flows of 3000 gpm.
Operating our influent pump station at high flowrates to minimize surcharges in the collection systems .
We also received some help from our customers, as follows:
At the Slater Road pump station, we were at a high water alarm level. The Town of Cary has a nearby sewer
system, and it had capacity. The Town approved our pumping to their sewer system if we were faced with
overflow. We set up a portable pumping system, but never had to use it as the flow subsided before the pump
station reached its maximum capacity. The Town of Cary monitored their system during this portion of the
event. We appreciate the assistance from the Town.
Our largest flow industrial user, Cree, has a large equalization basin, and at approximately 6:30 p.m. we asked
them to stop their flow for as long as possible. They stopped their flow for about 2 hours. This gave Stirrup Iron
pump station some relief during the peak flow period.
Based on our current conditions and the stormy hot season ahead, we have chosen to begin wasting sludge to Train 3
and will begin bringing it online in the next few days. Bringing a train online smoothly is a difficult operation and we will
make every effort to do so without violating any effluent standards. If we have any problems we will let you know as
soon as possible.

should pass these numbers along to both of you.
The attached spreadsheet shows the Triangle WWTP in Durham County is currently at 88.69% capacity.
Let me know if you need anything else, or if you'd like it reported in any other format, etc.
