Subject: NPDES Permit Issuance
Permit No. NCO023876
South Burlington WWTP

Dear Mr. Shoaf:
In accordance with the application for a discharge permit received on July 27, 1995, the Division is
forwarding herewith the subject NPDES permit. This permit is issued pursuant to the requirements of
North Carolina'General Statute 143-215.1 and the Memorandum ofAgreement between North Carolina
and the U.S. Environmental Protection Agency dated December 6, 1981
In response to your December 8, 1995 letter concerning the NPDES draft permit no. NCO023876 for the City
of Burlington, we have addressed your specific concerns. In addition to your concerns which are addressed
below, a review of the subject permit by the Division of Environmental Management revealed an error in the
effluent limitations sheets. The weekly average for cadmium was listed as 2.0 ug/1 on the sheets that you
received in your draft permit package. The cadmium limit should be 2.3 ug/l.
The State has addressed your specific concerns and questions raised in the December 8, 1995 letter as
follows:
- Regarding sampling above the dam on Saxapahaw Lake, the condition stated in -your letter has been
included in the sampling footnote on the effluent limitations and monitoring requirements page.
- The discharge limitation for total phosphorus has been changed back to a quarterly average of 2.0 mg/1
derived from weekly samples. The monthly average/monthly monitoring is based on a recent DEM policy
decision that states new and expanding facilities will have to abide by the this monthly requirement. Existing
facilities that are not expanding will not have to abide by this requirement.
- Conductivity monitoring of three times/week is required at both the effluent and upstream and downstream
stations.
- The sample type for cyanide monitoring has been changed from composite to grab.
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, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is
made, this decision shall be final and binding.

and in so far as possible at the same time of day.
REPORTING REQUIREMENTS
Data entered on a form approved by the Division and summarized in an annual report due by January first of the
year immediately following the summer period when sampling occurred.
Yearly monitoring reports shall be sent to:
Instream Assessment Unit
DEM Water Quality section
P.O. Box 29535
Raleigh, NC 27626-0535

Part III Permit # NCO023876
H) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is
86 % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed after thirty days from the effective date of this permit 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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally,
DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

South Burlington WWTP Sludge Management Plan
for NPDES Permit Application
The South Burlington WWTP method of disposing of treatment plant sludge
(biosolids) satisfies the requirements of the 40 CFR 503 regulations. The treatment plant
operates a land application sludge management program under non -discharge permit
number WQ0000520 issued by NCDEM to the City of Burlington.
The sludge management program includes disposal of both primary -and secondary
sludge. The treatment plant has the ability to thicken the sludge by gravity or by using a
dissolved air floatation (DAF) unit. Thickened primary and secondary sludge are
combined and held in aerated storage prior to stabilization. As space becomes available,
this thickened sludge is transferred to lime stabilization contact tanks for stabilization with
hydrated lime to pH 12 for > 2 hours and > pH 11.5 for the remainder of the 24 hours.
This sludge is then stored and maintained at pH 11.0 or higher until it can be applied to
farmland. The South plant also has aerobic digestion as an alternate stabilization method.
This method is utilized during the warmer months of the year when temperatures are
appropriate. Land application as a liquid sludge from either stabilization process" is by
surface spray or subsurface injection. The City has permitted over 2500 acres for the
sludge management program. The City contracts with a biosolids management company
to perform the site applications and assist with record keeping and reporting.

SECTION 11. BASIC DISCHARGE DESCRIPTION
Complete this section for each present or proposed discharge Indicated in Section I, Mena 7 and 8, that Is to surface waters. This
Includes discharges td other municipal sewerage systems In which the waste water does not go through a treatment works prior to
beingg discharged to atrlaoe waters. Discharges to wells must be described where there are also dismarges to surface waters from
this taciltty. Separate descriptions of each discharge are required even M several discharges originate In the same facility. AN values
for an existing discharge should be representative of the twelve previous months of operation. M this Is a proposed discharge, values
should reflect best engineering estimates.

Page 1 of 13

INSTRUCTIONS
The purpose of this document and the NC DEHNR memo of October 30, 1990 (Tedder)/mailing of December 1990 is to standard-
ize the sampling, analysis and reporting procedures to be used for the Annual Pollutant Analysis Monitoring (APAM) Require-
ment as described in the permit.
Sampling
1 - Take a 24-hour composite sample from the final effluent during mid -week (Wednesday through Friday). Collect a grab
sample for the volatile organic fraction when collection of the 24-hour composite sample is completed. Follow any other
sampling instructions provided by the laboratory performing the analysis.
2 - Indicate in the space provided on Page 1 of 13 this page whether a corresponding sample for toxicity testing was taken.
3 - Make note of any unusual wastewater treatment operating conditions occurring on the day of sampling in the space pro-
vided on Page 1 of 13.
Analysis
4 - Analyze the effluent for pollutants listed on the APAM form, including those to be identified and approximately quan-
tified under the 10 significant peaks rule, using appropriate EPA -approved methods for each of the analytic fractions.
Other analytical methods can be substituted only with prior, written approval of the Director of the Division of Environmen-
tal Management (DEM). Read and distribute to the laboratory performing the analysis the accompanying memo (Tedder, October
1990) clarifying analytical requirements.
5 - Identify chemicals to be analyzed for according to the 10 significant peaks rule (as described in item 2 of the Annual
Pollutant Analysis Monitoring Requirement in the permit) using a GC/MS library search. Tentative identification is all that
is required; confirmation by standard injection is not necessary. Estimate the concentration of each based on an internal
standard having the closest retention time.
Reporting
6 - Quantitation Limit Targets that should be met are listed on this Revised APAM Reporting Form A. Report the use of any
higher quantition limit and an explanation as to why the listed quantitation limit target could not be met. Examples of
acceptable reasons for not meeting a quantitation limit target could be high background concentrations in a sample, or the
necessity for sample fraction dilution to bring a chemical to within a quantifiable concentration. List any quantitation
limit different (whether higher or Lower) from the target in the column provided for the purpose.
7 - If a chemical is found to be below the quantitation limit, report the concentration detected as Less than (or '<') the
quantitation limit in the appropriate space. Provide a concentration estimate for chemicals detected in concentrations
greater than the detection limit and less than the quantitation limit. Enter the detection limit in parentheses beside the
estimate: Chemicals detected in concentrations above the quantitation limits must be quantified. Quantitation limit and
detection limit are defined in the NC DEHNR memo (Tedder, October 1990). Enter the total number of peaks detected in
each analytic fraction in the appropriate space on this Revised APAM Form A. Report all concentrations in units of micro-
grams per liter (ug/L) and metals as total recoverable metal. If no peaks to be identified under the 10 significant peaks
rule are observed, enter "none" in the space provided for "other" compounds in each appropriate analytic fraction section.
Provide the concentration estimate and retention time for "unknowns" as well as for "significant peaks" for which a struc-
tural assignment can be made.
8 - If "significant peaks" are found, provide probable molecular weight, library match probability, retention time-, ident-
ification basis, and MS scan number each. In addition, list Internal standards and their retention times.
9 - In the section Labeled "Organic Analytical Information", (Page 11 of 13) include for each organic fraction the method,
extraction technique, GC operating conditions, and surrogate recovery. Report the size of the GC/MS library being utilized
in the appropriate space.
10 - Use copies of this Annual Pollutant Analysis Monitoring Revised Form A to report the results of the analysis. Both
the analytical Laboratory representative and the facility operator in responsible charge should sign completed forms
(last page).
11 - Mail two completed copies of the form (and the laboratory report, If submitted to the facility on a different form)
to: ATTN: Central Files, Division of Environmental Management, NC DEHNR, P.O. Box 29535, Raleigh, NC 27626. Mail the APAM
form separately from Discharge Monitoring Reports.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Per Basin Management Strategy, (section 6.5 Toxic -Substances) -Burlington - East, Graham, and Burlington
- South were reviewed and allocated based upon a new toxics pro cedure utilizing a statistical review and
analysis of current effluent data.
The current permit requirements for Burlington - East, Graham, and Burlington - South collectively contain
seven instream monitoring sites, (some which are monitored by two different facilities) : SR 1712
(Hopedale Road), Highway 54, SR 2116 (bridge over Haw River), Highway 87 (bridge over Big Alamance
Creek), SR 2116 (bridge over Big Alamance Creek), Saxapahaw Lake (above dam), and SR 1005.
Recommendations for permit renewals will not change these sites, but the Technical Support Branch
requests these facilities coordinate instream monitoring under the guidance of the Winston - Salem Regional
Office. Recommendations from the Technical Support Branch would be a collective effort to monitor
instream on the same day and if possible at the same time of day.
Recommendations for parameters to be monitored instream will change for some of these permits. For
example, those permits which previously contained BOD5 and NH3-N monitoring will no longer be
required to take these samples. Instead, all three of these permits will need to take instream TP and
orthophosphate samples as well as temperature, dissolved oxygen, fecal coliform, and conductivity.

CHRONIC Tommy':PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 86 % (defined as treatment two in the North Carolina procedure document). The permit
holder shall perform guarterb monitoring using this procedure to establish compliance with the permit
condition. The first test will be performed after thirty days from the effective date of this permit during
the months of Jan., Apr., Jul., and Oct. Effluent sampling for this testing shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code
TGP3B. Additionally, DEM Form AT -I (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test and will require
immediate retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will
constitute noncompliance with monitoring,requirements.

1976: WLA for 8.0 mgd w/ limits of 14 mg/I BOD5 , 6 mgA NH3-N, 5 mg/I dissolved oxygen, 30 mg/I TSS, 200/100 mL fecal coliform,
and 6 - 9 SU pH. No toxics requirements.
1982: facility expanded to 9.5 mgd and limits of 12 mgA BOD5 , 4 mgA NH3-N, 5 mgA dissolved oxygen, 30 mg/i TSS,
1,000/100 mL fecal coliform, and 6 - 9 SU pH were decided upon, (Level C model was developed). No toxics requirements.
1984: Toxicity testing of effluent begun, results indicated effluent not that toxic, nor were any metals or organics present in elevated
levels, (except zinc and copper). Instream data both up and downstream from facility was poor, but a benthic study could not
attribute the degradation to the facility effluent. Various flow increases by SIU's were requested as well as reviews of toxicants
and inhibition rates using EPA estimates!
1985: reissued with same limits for 9.5 mgd, (summer / winter) and addition of 0.25 µgA mercury and monitoring for aluminum and zinc.
1987: reissued with same conventional limits for 9.5 mgd and 2.0 mg/I total phosphorus, 58 µg/I chromium, 0.2 µg/I mercury,
2 µg/I cadmium, 61 µgA nickel and monitoring for copper, zinc, lead, cyanide, and 'aluminum, (based on predicted outcome using
influent data). Instream monitoring and a chronic toxicity test was also recommended.
1989: two issues were dealt with extensively during this review; possible expansion of this plant and others in the vacinity and ability of
both Burlington and the Graham's plant to meet the 2.0 mgA total phosphorus limit, (extension were requested by all three
plants). Extensive modeling notes are present, but no model output is in the file; various model inputs were requested at that
time, (worth reviewing). The facility was planning an expansion from 9.5 mgd to 12 mgd at that time. An EA was pushed
through without thorough review and Clements was working towards holding up the process until the requested modeling input
was received.
1990: a scathing memo from Tedder to Construction Grants indicating that the EA did not address a possible expansion of the
discharge and that the facility has gone ahead with expansion plans and received funding to do so. Letter from Tedder to facility
followed this memo informing them that the WLA process and permit would not be issued without receiving the requested
modeling information. Facility replied that an upstream dam project underway and not slated for completion for a couple years
would make this information invalid. A WLA was finally processed w/out this additional information, (the model rates and inputs
were printed out but not the predicted instream DO's). The limits were based on keeping the loading the same, but attached to
the Fact Sheet was a memo indicating that Advanced Tertiary treatment should be required, but that it was unknown what
assimilative capacity the Haw River has for these levels of treatment. Final limits for 12 mgd were 9 (18) mgA BOD5 ,
3 (6) mg/l NH3-N, 5 mgA dissolved oxygen, 30 mgA TSS, 200/100 mL fecal coliform, 2.0 mg/I total phosphorus, and 6 - 9 SU pH,
as well as various other metals limits, toxicity testing, and more extensive instream monitoring requirements. The facility
questioned a number of the requirements. An SOC was.requested later that year for the expansion process.
1993: reissued with same limits and addition ofjtoluene and fluoride limits, (after twelve months of monitoring) due to APAM review.
Lead was also limited and silver monitoring required per Pretreatment information

Instream Monitoring
The first downstream site is on Big Alamance Creek below the discharge. This site is consistently 1 - 2 °C higher than the upstream
site. It should be noted that the discharge is only 0.4 miles from the mouth of Big Alamance Creek into the Haw River where even
higher temperatures are prevalent. Although the regs. allow up to a 2.8 °C change in water temperature, [ T15A: 02B .0211 (b) (3) (J)
I will note this consistent effect on the Fact Sheet.
The first downstream site is also revealing increased instream concentrations of PO4 (ranging from approximately 0.2 - 0.5 mgA ; the
upstream site is consistently < 0.05 mg/1).
The second and third downstream sites are on the Haw River mainstem and do not reflect the influence of this discharge only. This
information may be useful if a more calibrated modeling analysis of the three main discharges is.undertaken.

t Toxich Testing
The tests were very up and down for awhile, plus the facility was taking them every month, (they are limited quarterly) I e-mailed Matt
Matthews about this and his reply was: "[They] came out from under a special order on 3/31/95. They're not completely convinced that
their toxicity problems are gone and are still employing BRI to do research. Thus the monthly testing."
will not recommend any changes.
APAM
reveals virtually same concentrations as previous review; these levels are below the State or Federal standards which would apply. I
will note the re -occurrence of toluene at 2.0 µgA, but will not recommend monitoring.

The current permit requirements for Burlington East, Graham, and Burlington - South collectively contain seven instream
monitoring sites, (some which are monitored by two different facilities) : SR 1712 (Hopedale Road), Highway 54, SR 2116
(bridge over Haw River), Highway 87 (bridge over Big Alamance Creek), SR 2116 (bridge over Big Alamance Creek),
Saxapahaw lake (above dam), and SR 1005.
Recommendations for permit renewals will not change these sites, but the Technical Support Branch requests these
facilities coordinate instream monitoring under the guidance of the Winston - Salem Regional Office. Recommendations
from the Technical Support Branch would be a collective effort to monitor instream on the same day and if possible at the
same time of day.
Recommendations for parameters to be monitored instream will change for some of these permits. For example, those
permits which previously contained BOD5 and NH3-N monitoring will no longer be required to take these samples. Instead,
all three of these permits will need to take instream TP and orthophosphate samples as well as temperature, dissolved
oxygen, fecal coliform, and conductivity.
Recommended instream monitoring locations and sampling protocol if coordination between facilities is not chosen:
City of Graham Waste Water Treatment Plant
NC0021211
Upstream Location: NC Highway 54
Downstream Location: SR 2158 (above the dam) `
Parameters: Temperature, dissolved oxygen, fecal coliform, conductivity, TP **, and PO4 "
Special instream monitoring locations or monitoring frequencies:
Stream samples shall be collected three times per week during the months of June, July, August,
and September and once per week during the remaining months of the year.
` NOTE cover page for option of coordinated stream sampling between facilities.
*` Orthophosphate need only be taken during months of June, July, August, and September.

Subject: Instream and Effluent Monitoring of Orthophosphate
Graham WWTP, NC0021211
Burlington - East WWTP, NCO023868
Burlington - South WWTP, NCO023876
Alamance County
Wasteload allocations for these three facilities were completed in November,
1995. Since that time, the Rapid Assessment Group has been reviewing our instream
monitoring requirements and data needs. We have come to the conclusion that, for
this cluster of facilities, the need and usefulness of orthophosphate (PO4) is not
outweighed by the difficulties associated with sampling for this parameter. Therefore,
we are recommending that the requirements for orthophosphate sampling at the
effluent and instream be removed from the permit. All other requirements should
remain as outlined in the memorandum dated February 9, 1996.

.0004 DEFINITIONS
The following definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physicaVchemical method for reducing soluble organic material from wastewater effluent; The column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square fool and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant she;
(2) Aerated Lagoons. A basin In which all solids are maintained in suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, agitation or diffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agriculturally managed she. Any she on which a crop is produced, managed, and harvested (Crop includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium Ion Is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed impurities;
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve .'secondarym effluent limits;
(8) Centrifuge. A mechanical device in which centrifugal force is used to separate solids from liquids or to separate liquids of different dense. as;
(9) Chemical Addition Systems- The addhlon of chemical(s) to wastewater at an application point for purposes of improving solids removal, pH adjustment,
alkalinity control, etc.; the capability to experiment with different chemicals and different application points to achieve a specific result will be considered one
system; the capability to add chemicals) to dual units will be rated as one system; capability to add a chemical at a different application points for different
purposes will result in the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
Its application to a dewatedng device;
(11) Closed Cycle Systems Use of holding ponds or holding tanks for containment of wastewater containing inorganic, non -toxic materials from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nitrification- A single stage system required to achieve pennh effluent limits on BOD
and ammonia nitrogen within the same biological reactor,
(13) Dechtorination. The partial or complete reduction of residual chlorine in a liquid by any cherrdcal or physical process:
(14) Denitrificatlon Process. 'the conversion of nitrate -nitrogen to nitrogen gas;
