Subject: Issuance of Permit Modification
NPDES Permit NCO026051
Durham County Triangle WWTP
Durham County
Dear Mr. Hill:
Division staff have reviewed and approved your application for an NPDES permit
modification. Accordingly, the Division is forwarding the subject modified pages. This
permit 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 May 9, 1994 (or as subsequently amended).
There were no comments received during the 30-day public comment period for this
proposed modification. Therefore the permit modifications, effective immediately, are as
follows:
Change the effective date for annual mass limits for total nitrogen (100,452 lbs/yr) and
total phosphorus (10,204 lbs/yr) from January 1, 2005 to May 1, 2005. As discussed in
your letter dated 10/27/2003, this additional time is needed to complete the Phase II
construction, which has been delayed several months due to wet weather and sludge
removal problems. The Phase II construction will include the installation of the
biological nutrient removal facility. The TN annual load limits were supposed to become
effective 1 / 1 /2003 based on House Bill 515 requirements; therefore, this additional 4-
month compliance period puts the total compliance schedule at 28 months. Please note
that this facility must continue to comply with the current TP concentration limits of 0.5
mg/1 (summer) and 2 mg/1 (winter).
Addition of weekly average ammonia limits to Effluent Sheets AM and A(2), in addition
to the current monthly average limits. Both limits are necessary to comply with 40 CFR
122.45(d). The weekly average limits are based on a review of performance data for
several municipalities, and a multiplier of 3 was used to derive the weekly average limit.
All permits with monthly average ammonia limits are subject to this implementation
policy. With the addition of these limits, Special Condition AV)- Ammonia Reopener-
has been deleted.
If any parts, measurement frequencies, or sampling requirements contained in this permit
modification are unacceptable to you, you have the right to an adjudicatory hearing upon

written request within thirty (30) days following receipt of this letter. This request must be
in the form of a written petition, conforming to Chapter 150B of the North Carolina General
Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be
final and binding.
Please take notice that this permit is not transferable except after notice to the Division.
The Division may 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, the Division of Land Resources, the Coastal Area
Management Act, or any other federal or local governmental permit.
If you have any questions concerning this permit modification, please contact Tom Belnick
at telephone number [phone], extension 543.

Hello folks- This facility had a 2-year compliance schedule to meet HB515
limits for total nitrogen (TN limits to kick in 1/l/05 following
construction upgrades, including biological nutrient removal). The
facility just requested an additional 4 months in the compliance schedule
(till 5/l/05) due to construction delays (removing sludge from lagoon;
I'll copy letter to you). Anyways, I don't have a problem with their
request, since EPA does allow up to a 3-year compliance schedule. Let me

Re: Durham County Triangle Wastewater Treatment Plant
NPDES Permit NCO026051
Dear Mr. Belnick:
Durham County respectfully requests the Division of Water Quality's consideration to
amend the current NPDES permit for the 12.0 MGD effluent limitations and monitoring
requirements to start May 1, 2005 in lieu of January 1, 2005. As you are aware, the
project has received A-T-C for the Phase I and Phase II improvements.
The Phase I construction is currently substantially complete, and is approaching final
completion. The Phase II contractor was issued a Notice to Proceed dated January 1,
2003 with a final completion date of January 5, 2005. However, there were difficulties
associated with removing the sludge from the west lagoon that have impacted the
schedule. These difficulties were encountered due to wet weather, the size of the lagoon
(5 acres), and the consistency of the lowest layers of sludge. The sludge could not be
pumped because it was too thick, and could not be pushed because it was too thin. While
all of these issues were resolved and the sludge was removed, the completion date has
been pushed back almost 4 months.
As you consider this request, I would like to provide some information about the current
level of progress on the project:
120 E. Parrish Street, Law Bldg., Ist Floor, Durham, N.C. 27701 [phone] Fax [phone]
Equal Employment/Affttmative Action Employer

The Phase I facilities (Influent Pump Station, Screening, Grit Removal, Flow
Measurement, Effluent Pump Station, Ultraviolet Disinfection, and Post
Aeration) are in service. These replacements of the older facilities provided
the newer facilities for reliability, eliminated many flooding issues related to
the elevations of the older structures, and eliminated the use of chlorine for
disinfection that was contributing to VOC (Volatile Organic Compounds)
violations of the NPDES permit.
■ The Phase II contract is well under way. The west lagoon is now filled and
compacted to enable construction to proceed. The Influent RAS structure has
been poured. Several slab and wall sections of the BNR facility have been
poured. The Clarifier Distribution Box has been poured. Four of the five
Sand Filter structures are in place. The lower slab of the RAS/WAS Pump
Station is in place and the walls are being poured. Chemical Feed structures
are standing.
Durham County is committed to a successful completion of the project, and is expending
significant time, effort, and financial resources to fulfill that commitment. We are
confident that the delays that have occurred have been for reasons that are behind us and
are not expected to happen again. We are comfortable with the request for the extension
to May 1, 2005, and fully expect to bring the project to completion by that date.
We appreciate your consideration of this request, and would be glad to meet with you to
discuss this request in more dadl:1-9, If you have any questions or need additional
information, please contact me at 560-7992.
