Subject: Issuance of NPDES Permit NCO023876
South Burlington WWTP
Alamance County
Dear Mr. Shoaf:
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).
There are two changes to this permit from the draft previously sent to you for review:
➢ The sampling frequency for nutrients has been changed to once per week from three per week with the
expectation that more frequent sampling may be requested for a specific time period to support modeling.
➢ Conductivity measurement has been changed to daily from weekly in accordance with 15A NCAC 2B .0500
The limit for mercury will remain, as the RPA determined there is a possibility to exceed water quality
standards. The Reasonable Potential Analysis is an EPA requirement, and is conducted at each permit renewal cycle.
If the data at your next renewal cycle shows no RP for any parameter, that limit will be removed. You must continue
to monitor and report on Total Residual Chlorine on a daily basis. The TRC limit of 19 ug/L takes effect on April 1,
2007 which is 6 months after the effective date of this permit. Monitoring is required beginning with the permit
effective date.
If any parts, measurement frequencies or sampling requirements contained in this permit 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 demand is made, this decision shall be final and binding.
Please note 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 or permits required by the Division of Land
Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be
required. If you have any questions concerning this permit, please contact Jim McKay at telephone number (919)
733-5083, extension 595.

Permit NCO023876
A. (3.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 86%.
The permit holder shall perform at a minimum,guarterlg monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of January, April, July and October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum,
in each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ
Form AT-3 (original) is to be sent to the following address:
Attention:North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and
all concentration/response data, and be certified by laboratory supervisor and ORC or approved
designate signature. Total residual chlorine of the effluent toxicity sample must be measured and
reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT)
test form indicating the facility name, permit number, pipe number, county, and the month/year of
the report with the notation of "No Flow" in the comment area of the form. The report shall be
submitted to the Environmental Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival, minimum control organism reproduction, and appropriate environmental
controls, shall constitute an invalid test and will require immediate follow-up testing to be completed
no later than the last day of the month following the month of the initial monitoring.

BACKGROUND
The South Burlington WWTP is one of two wastewater treatment plants for the City of
Burlington. In addition to the City of Burlington, the plant serves the Village of Alamance,
Town of Elon, Town of Gibsonville, City of Graham, and the Town of Swepsonville, — a total
population of 32,635. South Burlington has a frill pretreatment, program with 12 Significant
Industrial Users and will continue to implement this program in the new permit term. A Staff
report was received; the Regional Office recommends renewal.
The South Plant discharges to Big Alamance Creek in the Cape Fear River Basin. This river is
classified as nutrient sensitive waters (NSW). In keeping with the Cape Fear River Basin
nutrient permitting strategy for Jordan Lake, the following changes have been made: 1. a re -
opener clause has been added to allow for modification of effluent limitations, monitoring and
reporting requirements as needed, 2. changing sampling requirements for Nitrogen and
Phosphorus to 1/week, and 3. requiring calculation of Total Nitrogen Load and Total
Phosphorus Load on a monthly and annual basis.
The City of Burlington is a member of the Upper Cape Fear River Basin Association to monitor
nutrients and other water quality parameters in the basin. DNIR data from January 2004 through
January 2006 were reviewed. Data are summari2ed below.

Instream Monitoring and Verification. of Existing Conditions:
Instream data from January 2004 through July 2005 was examined for temperature, dissolved
oxygen (DO), fecal coliform, total phosphorus; and conductivity. There was an average
difference of 0.7 degrees Celsius between upstream and downstream temperature values. On 4
occasions instream dissolved oxygen levels downstream of the discharge were below the 5-mg/L
standard. It should be noted that on 2 of these 4 occasions, the downstream dissolved oxygen
level was higher than the upstream DO levels.
Results of Reasonable Potential Analysis (RPA):
A reasonable potential analysis (RPA) was performed for all monitored parameters. It was
determined that there is reasonable potential for mercury to violate water quality standard.
Therefore, a limit and monitoring have been added. Cyanide was shown to have no RP and the
limits will be removed, but monitoring will, remain. Copper and zinc showed RP, but they are
action level standards and no toxicity has been observed so monitoring only will remain. All
other parameters showed no RP and will remain as monitored in the LTMP.
Correspondence:
In this permit term, there have been no Notices of Violation (NOV) given to the facility. Two
enforcement cases were made, one in March 2003 for TSS and BOD weekly average violations
and one in April 2003 for weekly average and monthly average BOD violations.
PERMITTING STRATEGY AND SUMMARY OF PROPOSED CHANGES
Due to the results of the reasonable potential analysis, the cyanide limit will be removed from
this permit and monitoring reduced. Mercury monitoring and a limit will be added. A TRC limit
and weekly average NH3 reporting are being added.
All the other parameters will remain the same in accordance with the previous permit and 1995
WLA.
The permittee will be required to continue to implement its existing pretreatment program in this
permit issuance.

RE: Draft NPDES Permit No. NCO023876
South Burlington WWTP
City of Burlington, Alamance County
Dear Mr. McKay:
D E C E d�
J U L 7 2006
DENR - WATER QUALITY
POINT SOURCE BRANCH
I have reviewed the draft NPDES permit NCO023876 for the South Burlington
WWTP and have the following questions and comments.
• The City of Burlington understands the addition of Weekly Average limits for
ammonia. A review of historical data does not indicate that we will have
prolonged difficulty meeting these limits. Nitrification is a biological process and
there may be times when the biological conversion of ammonia to nitrite and
nitrate will be disrupted. We will try to minimize those events.
• The City of Burlington understands that the limit has been removed for cyanide.
We will continue to monitor according to the new permit requirements.
• The City of Burlington will have to purchase equipment and train staff at the plant
to sample and analyze for low-level chlorine residual_ The draft permit states that
the low-level chlorine residual limit will take effect 18 months after the effective
date of the final permit. The City requests clarification and confirmation that
the requirement for monitoring also begins when the limit takes effect. We
will have to test our procedures and methods prior to the limit being effective, and
will need the lead time without the monitoring requirement in order to set up our
program.
• To date the only requirement for monitoring mercury at the South Burlington
WWTP is as part of the quarterly pretreatment headworks analysis. The
reasonable potential calculation used to add a mercury limit to our permit is
somewhat subjective in its assumptions. A review of the plant effluent low level
mercury results indicates that mercury is not out of control at the plant discharge.
Imposing a limit in the permit increases the frequency of sampling and analysis,
and the time required for sampling, analysis, reporting and compliance. We
request that the decision to include a mercury limit in this draft permit be
reviewed, and hopefully the limit will be removed. If this limit remains in our

permit, and there are no violations in the next five-year cycle, the City requests
that this limit be dropped from future permits regardless of the results of the
reasonable potential analysis. The low-level mercury results are provided below
for your reference.

The City of Burlington understands that as the rules for the nutrient control strategy for
the Jordan Lake Watershed are developed, approved, and implemented there will be
changes in the requirements (re -opener clause) for the various entities within the
watershed. We will take that opportunity to provide comments as necessary.
What is not clear is the reasoning for changing the nitrogen and phosphorus monitoring to
a frequency of 3 times per week. According to the documentation used in development
of the Jordan Lake Watershed nutrient management strategy the contribution of nitrogen
loading at the lake is only 28% from point sources on the Haw River Arm vs. 72%
nitrogen loading from the non -point sources. Also, these same documents show that the
contribution of phosphorus loading from point sources is 16% and 84% from non -point
sources. Currently the proposed rules do not require any non -point source monitoring
which is the segment with the largest loading at the lake. This doesn't make sense.
To our knowledge after a brief informal survey, dischargers in the Neuse River Basin and
the Tar Pamlico basin are not required to monitor three times a week. These basins are
facing similar nutrient management concerns, but apparently heightened monitoring
(three times per week) was not considered to be of sufficient benefit to make it a
requirement in those permits.
Another argument presented by DWQ is that the increased data collection activity would
be used for special studies and additional modeling. The DWQ monitoring group has

stated that they do not have the resources to perform additional modeling in the Jordan
Lake Watershed. Therefore without plans to use this data for modeling there is little
reason to collect the data for archival purposes.
The municipalities in the Haw River Watershed are funding stream monitoring on the
tributaries draining into the Haw River Arm of Jordan Lake. This monitoring is twice per
month for some parameters, once per month for some additional parameters, and
quarterly for some metals of interest. The DWQ is proposing to monitor the Jordan Lake
water quality 12 times per year (monthly) during their 2 intensive sampling years, 6 times
per year during the 1 less intensive year, and no sampling at all for 2 of the next 5 years.
With those sampling frequencies, requiring the NPDES discharge permit holders to
sample 3 times per week for nitrogen and phosphorus does not make sense. This does
not add any resolution to the potential models or to our understanding of the lake,
especially if there is no lake monitoring in progress.
The DWQ modeling group suggested that the additional sampling would allow a better
determination of compliance by having more data points. This is not a good argument, or
else the same would hold true for the Neuse and Tar Pamlico basins. The method for
determination of compliance is defined by the State, and should be uniformly applied.
Our existing permit requires monitoring nitrite — nitrate and TKN monthly, and the
phosphorus monitoring is required weekly. It would be logical to require weekly
monitoring for both nitrogen and phosphorus at the wastewater treatment plants. This
would create a more robust database than is currently available. The City of Burlington
would support a requirement for weekly monitoring for the nitrogen and phosphorus
concentrations in the effluent and monthly and annual loading compliance
determinations.

Marshall:
Thank you for your prompt reply to my request for a review of NPDES Permit reissues.
I sent two different files recently, one is Permit NC0023.876, for the South
Burlington WWTP; the other is Permit NCO024881 for the town of Reidsville WWTP. From
the comments in your review, I suspect you are referring to NCO023876 for the South
Burlington WWTP. Please confirm this. Your attempt to email me probably failed
because although I go by Jim McKay, my email address is James.McKay
To reply to your comments in order, I have been an NPDES permit writer for almost 20
minutes. (Actually I started in early May. I am attending the EPA training class in
Austin, TX next week.). I try to be as prompt as I can be in replying to requests.
1. I will add the pretreatment language to the fact sheet. I updated an existing
fact sheet that did not have this wording.
2. I will make the suggested changes to A.1 and footnote 2. Again, this was the
wording in the old permit document that I revised.
3. a. I will add "Total" to mercury b. I will show the mercury limit as 14_.0 _
C. I will specify Method 1631_E_ in footnote 8.
4. I will add the standard condition that requires annual sampling of the pollutants
required by form 2A. No excuse, but again it was not in the existing permit that I
revised for this go -round.
I look forward to working with you in the future.
Best regards,
Jim McKay

Jim:
Welcome. How long have you been at DENR permit writing? I hope the
following comments are useful to you. I try to complete my review asap
after receiving your draft permit materials, so we have time to resolve
any concerns. when might you be able to respond to these comments? I
send a no comment letter when I receive your response and all comments
are addressed. Feel free to call me at 404-562-9304 if you want to
discuss further. Marshall
1. based on the fact sheet, the permittee obviously runs a pretreatment
program. NC has historically agreed to our request that the fact sheet
contain language something like "the permittee will be required to
continue to implement its existing pretreatment program in this permit
issuance". Your fact sheet does not contain that language. Would you
add this or something similar to it?
2. recommend changing "total suspended residue" to "total suspended
solids" in A.1 and footnote 2.
3. a. mercury should be expressed as "total"
b. fyi, as written, the 14 ng/l limit would not be violated if
14.3 ng/l was reported. I f you want 14.3 ng/l to be a violation,
the limit should be expressed as 14.0 ng/l.
C. recommend specifying Method 1631E in footnote 8.
4. The draft permit does not contain the standard (last) condition
that requires annual sampling of the pollutants required by Form 2A.
Why not?

BACKGROUND
The South Burlington WWTP is one of two wastewater treatment plants for the City of
Burlington. In addition to the City of Burlington, the plant serves the Village of Alamance,
Town of Elon, Town of Gibsonville, City of Graham, and the Town of Swepsonville — a total
population of 32,635. The facility also treats waste from twelve Significant Industrial Users
(SATs), amounting to about 1.00 MGD. A Staff report was received; the Regional Office
recommends renewal.
The South Plant discharges to Big Alamance Creek in the Cape Fear River Basin. This river is
classified as nutrient sensitive waters (NSW). In keeping with the Cape Fear River Basin
nutrient permitting strategy for Jordan Lake, the following changes have been made: 1. a re -
opener clause has been added to allow for modification of effluent limitations, monitoring and
reporting requirements as needed, 2. changing sampling requirements for Nitrogen and
Phosphorus to 3/week, and 3, requiring calculation of Total Nitrogen Load and Total
Phosphorus Load on a monthly and annual basis.
The City of Burlington is a member of the Upper Cape Fear River Basin Association to monitor
nutrients and other water quality parameters in the basin. DMR data from January 2004 through
January 2006 were reviewed. Data are summarized below.

NPDES NCO023876 Renewal

NCO023876 Data Summary (January 2004-January 2006)
r
Instream Monitoring and Verification of Existing Conditions:
Instreamn data from January 2004 through July 2005 was examined for temperature, dissolved
oxygen (DO), fecal coliform, total phosphorus, and conductivity. There was an average
difference of 0.7 degrees Celsius between upstream and downstream temperature values. On 4
occasions instream dissolved oxygen levels downstream of the discharge were below the 5-mg/L
standard. It should be noted that on 2 of these 4 occasions, the downstream dissolved oxygen
level was higher than the upstream DO levels.
Results of Reasonable Potential Analysis (RPA):
A reasonable potential analysis (RPA) was performed for all monitored parameters. It was
determined that .there is reasonable potential for mercury to violate water quality standard.
Therefore, a limit and monitoring have been added. Cyanide was shown to have no RP and the
limits will be removed, but monitoring will remain. Copper and zinc showed RP, but they are
action level standards and no toxicity has been observed so monitoring only will remain. All
other parameters showed no RP and will remain as monitored in the LTMP.
Correspondence:
In this permit term, there have been no Notices of Violation (NOV) given to the facility. Two
enforcement cases were made, one in March 2003 for TSS and BOD weekly average violations
and one in April 2003 for weekly average and monthly average BOD violations.
PERMITTING STRATEGY AND SUMMARY OF PROPOSED CHANGES
.Due to the results of the reasonable potential analysis, the cyanide limit will be removed from
this permit and monitoring reduced. Mercury monitoring and a limit will be added. A TRC limit
and weekly average NH3 reporting are being added.
All the other parameters will remain the same in accordance with the previous permit and 1995
WLA.

Subject: Installation of Emergency Gas Scrubbers
Dear Mr. Weaver:
This letter is to reiterate and clarify our conversation earlier today. The City of Burlington will be
installing emergency gas scrubbers to contain and mitigate any releases of chlorine or sulfur dioxide gases
at the South Burlington Wastewater Treatment Plant (WWTP) and East Burlington WWTP. The
scrubbers will be connected to the existing chlorine/sulfur dioxide buildings through a duct leading to the
scrubber.
This project does not affect the treatment process in any way, and is being done solely as a safety
measure. Based on our conversation, it was determined that an Authorization to Construct permit will not
be required for installation of the scrubbers.
Sincerely,
ALLEY, WILLIAMS, CARMEN & KING, INC.
