Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit 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).
This final permit includes the following major changes from the draft permit sent to
you on March 29, 2006:
➢ To support nutrient -sensitive modeling for the Jordan Lake watershed, nutrient monitoring
[Total Nitrogen, Total Phosphorus and nitrogen species] has been added. A summary of the
Division's nutrient monitoring strategy is enclosed for your reference.
> In response to your comment letter of April 21, 2006, the Total Residual Chlorine (TRC) limit
has been changed to 28 fig/L. The 7Q10 flow used for calculation in the draft permit was
incorrect.

JORDAN LAKE STRATEGY
(We had intended that the permits for the "Jordan Lake Project Partners" would include a Special Condition
requiring them to optimize their treatment operations for nutrient removal. The Partners already conducted
optimization studies and reported their findings to the EMC's Water Quality Committee in July 2000, as
required by SB1366. This new condition simply would have specifically required them to continue the
optimization efforts until alternate nutrient limits are established. However, we are still determining the extent
of the efforts and will proceed without them. If they become necessary, the re -opener clause allows us to add
them to the permits later.)

JORDAN LAKE STRATEGY
(SUBBASINS 30601-30606)
Background
The B. Everett Jordan Reservoir (Jordan Lake) was impounded in 1983. Its watershed includes the Haw River
(upstream of Jordan Dam) and New Hope River. All waters in the watershed are classified as Nutrient
Sensitive Waters (NSW). The reservoir is subject to algal blooms, and both the Upper New Hope and the
Haw River Arms are listed as Impaired waters on the Division's 303(d) list due to violations of the surface
water standard for chlorophyll a.
Dischargers to NSW waters are subject to mass limits equivalent to 5.5 mg/L Total Nitrogen (TN) and 2.0
mg/L Total Phosphorus (TP). However, affected dischargers can propose alternate nutrient limits if a
calibrated, nutrient -sensitive model demonstrates that those limits are sufficient to protect water quality. In
return, the dischargers must optimize their plant operations - that is, remove nutrients as well as they can with
their existing facilities - while they work to determine the alternate limits.
The "Jordan Lake Project Partners" (Burlington, Graham, Greensboro, Mebane, OWASA, Pittsboro, and
Reidsville) requested and received approval from the Environmental Management Commission (EMC) in
1999 to develop alternate limits for their discharges to Jordan Lake. The Partners completed their models, and
the Division has applied them to develop a TMDL and nutrient strategy. We originally expected to adopt
implementing rules in time for the 2006 permit renewals. Some of the Partners recently requested an
additional two years to continue monitoring in order to refine the models, and the EMC approved the request.
As a result, adoption of alternate nutrient limits will not occur in time for this year's permit renewal cycle.
Alternate limits may still be approved during the coming permit term.
The Modeling Unit has asked the NPDES Program to increase nutrient monitoring frequencies for the most
significant dischargers in this sub -watershed (not just the Partners) in order to support the continued
refinement of the Jordan models.
In the 2005 session, the Assembly passed Senate Bill 981, which, in effect, prohibits any new or expanding
discharge in the Jordan Lake watershed until nutrient allocations are established in rule. Therefore, we cannot
approve or add an expansion to any permit in this sub -watershed at this time.
Permit Requirements
(Note: This strategy does not fully address requirements for the Town of Pittsboro, permit NC0023541,
which is subject to the Robeson Creek TMDL and affected by the provisions of SB981)
Table 1 summarizes the nutrient -related requirements for dischargers in the Jordan Lake sub -watershed.
Dischargers are divided according to discharger (that is, wastewater) type and permitted flow, with breaks at
0.05 and 0.10 MGD.
Dischargers with flow limits of 0.1 MGD or greater account for 99.5% of the permitted flows to Jordan Lake.
These dischargers will monitor TN and TP 3/Week, report nitrogen species, and report TN and TP results as
both concentrations and mass loads. Their permits will include a Special Condition that describes how the
Permittee will calculate mass loads from concentration and flow data.
Smaller dischargers will monitor and report TN and TP (but not component species), monitor them less
frequently or not at all, and report results as concentrations only.
All permits in the watershed should include a re -opener Special Condition. In the event that the EMC adopts a
Nutrient Management Strategy or the EPA approves a TMDL in the coming permit term, the condition allows
the Division to re -open affected permits to set nutrient limits and related conditions accordingly.

Mr. Weaver:
I guess we don't have to like it, we just have to do it. The
chlorine residual monitoring will not reach the low levels until we purchase
the low level analyzer and train our staff. Until that time, and before
February 2008, we will be reporting TRC like we have been. To answer the
manganese question, we have a procedure to try out where we divide the
sample, measure the chlorine residual on one aliquot, use an aliquot of the
same sample, neutralize the chlorine, and analyze the chlorine residual
again (reagent blank) and subtract the blank from the first result to
determine the true chlorine residual. This is about the best idea we've
come up with so far. We will run multiple trials to verify this approach.
I am assuming that you will send me a signed final version of the
permit for my files.

Please substitute the attached file for the one sent with my previous

immediately, not in 2009. That effective date applies to a different
set of sub -basins in the Cape Fear.
Sorry for the confusion.

•

Dear Ms. Bryant:
I have reviewed the draft permit for the above referenced facility. As I am sure
you are aware, there are some problems with monitoring chlorine in the wastewater
discharge from water treatment plants. We suspect that the chlorine residual values that
we have been reporting are due either in part or whole to the presence of dissolved
manganese. I spoke with Dr. Phil Singer at the UNC-CH School of Public Health,
Department of Environmental Sciences and Engineering, and he doubted that what was
being measured in our lagoon system discharge could be residual chlorine. The only
source of chlorine would be the filter backwash water, and that is a small volume of
water with a relatively low chlorine residual at its source.
We utilize potassium permanganate (KmnO4) as a pre -oxidant for the treatment of
tastes, odors, and excessive manganese. We do not use this chemical all of the time, but
do use it intermittently when we are experiencing problems with our raw water quality.
In addition, there is naturally occurring manganese in the raw water, and even a small
concentration can interfere with the analysis of residual chlorine. Our lagoon system will
tend to concentrate the manganese that is removed in the sludge, and as the sediments go
anoxic/anaerobic, the manganese will re -dissolve and enter the lagoon water column.
Several water plants have investigated a de -chlorination treatment to remove
residual chlorine, but that portion comprised of manganese will not be affected by this
de -chlorination step. The City of Burlington intends to investigate the analytical
procedure in an effort to perfect the analytical method to minimize or remove the
interference caused by manganese.
The Town of Cary raised similar questions with DWQ, and DWQ has stated that
they will work with Cary to try to resolve the interference question. Apparently, Tom
Belnick with DWQ has stated that if the issue can't be resolved, it may be possible to
adjust the reporting limit in the permit to compensate for the manganese interference.
The City of Burlington would like the same consideration.

ti
Within the permit is a memorandum from Dave Goodrich dated June 19, 2003. In
the bullet points concerning a revised TRC policy, it states that "zero flow streams" will
have a limit of 17 ug/L and other streams will have a higher limit, up to 28 ug/L. Our
lagoon system does not discharge into a "zero flow stream" because we are required to
maintain a minimum discharge from the dam immediately upstream of the lagoon
discharge. The City would like for you to review the 17 ug/L limit and determine if it is
appropriate in this case.
The review of the draft permit did not raise any questions about the provisions
and requirements of the permit, other than the issues surrounding the requirements
concerning residual chlorine.
If you have comments by way of response, please contact me.
Sincerely,
Stephen R. Shoaf

capacity of 9 million gallons per day. A solids handling lagoon system was constructed
in the mid-1980's. The plant was expanded in 1993 when the dam was constructed to
create Lake Mackintosh. Located on the shore of Lake Mackintosh at 3400 Harris Road,
Burlington, this plant can treat up to 18 million gallons per day.
The water treatment process consists of coagulation, flocculation, settling, filtration,
chemical addition, disinfection, and pumping. The plant produces wastewater from
draining and cleaning the settling basins, and backwashing the filters. These wastewaters
have associated solids that have been chemically treated with aluminum sulfate for
coagulation. The filter backwash water can have a chlorine residual resulting from
disinfection of the filters and use of finished water during the backwash procedure.
Both the wastewater generated from cleaning the settling basins and the filter backwash
water flow to settling lagoons to separate the solids from the liquid. There is no sanitary
waste included in this wastewater. Pumps located at the lagoon are used to remove the
water form the lagoon. The lagoon supernatant is the liquid discharged to Great
Alamance Creek behind the Lake Mackintosh dam, and the subject of this NPDES permit
application.
There are two means of monitoring the amount of water discharged. There is a flow
meter that can be compared against the pump run times to verify the volumes discharged.
Maintenance on the meter and the pumps is part of our regular preventive maintenance
program.

Alamance Creek behind the Lake Mackintosh dam.
Our method of disposal of the water treatment plant sludge satisfies the requirements of
the 40 CFR 503 biosolids regulations and the 40 CFR 257 solid waste disposal
regulations. The treatment plant participates in a land application sludge management
program under non -discharge permit number WQ0000520 issued by NCDENR/DWQ to
the City of Burlington.
Solids are land -applied under this program to fields permitted by the State. The treatment
plant settling lagoons thicken the sludge by gravity. Thickened sludge can be combined
with our wastewater plant biosolids for land application, or applied directly to farmland.
Our practice is to top dress the water plant sludge with either nitrogen fertilizer,
potassium, or biosolids to improve the nutrient value to the farmer. The City of
Burlington has over 3100 acres of land permitted in our program. In 2004 approximately
3,640,000 gallons of sludge were land -applied. The City contracts with a biosolids
management company to perform the site applications and assist with record keeping and
reporting. Annual reports are submitted to the USEPA and NCDENR.
The City also holds a permit (No. WQ0021534) for Distribution of Residual Solids (503
Exempt) to distribute alum sludge residuals as a Class A product to be used as an
agricultural supplement. We have not distributed any solids under the conditions of this
permit to date.
