Subject: Issuance of NPDES Permit NC0047384
T.Z. Osborne WW IP
Guilford County
Division staff have reviewed and approved your application for an NPDES discharge permit. Accordingly. the
Division is forwarding the subject NPDES 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).
The following items address comments and changes made pursuant to the DRAFT permit:
▪ Mercury. A compliance schedule was requested for the proposed effluent limit for mercury, to allow time for
the facility to evaluate effluent results using clean sampling techniques and to investigate any potential
significant sources of mercury. The basis for the new mercury limit was the detection of mercury in 1 of 14
effluent samples collected during 1999/2000, at a concentration of 0.24 µg/L. Additional data collected
during 2001/2002 showed 2 mercury detections (0.24 µg/L and 0.28 µg/L) in 61 samples, which still exhibits
reasonable potential to exceed the water quality standard. Influent data collected during 2001/2002 showed
influent concentrations ranging up to 2.8 µg/L. Based on this data, the mercury limit remains in the FINAL
permit but includes a one-year compliance schedule, to provide the facility time for clean sampling
evaluations as well as source identification. In addition, please note that this facility will be required to begin
using EPA Method 1631 low-level mercury analysis beginning September 1, 2003 for all effluent mercury
monitoring, due to the limited dilution at this facility. This new analytical requirement was addressed in a
letter to the permittee dated August 30, 2002. Please note that effluent limits may be deleted in the future, if
the permittee provides updated effluent data (recommended one-year period) that shows no reasonable
potential to exceed applicable water quality standards. A subsequent request that the mercury compliance
schedule be extended until September 1, 2004 (to provide additional time for the facility to implement clean
sampling techniques) cannot be granted; the Division has already notified all 155 facilities (subject to the
requirement) to begin using Method 1631 for compliance purposes by September 1, 2003. Similarly, the
request for the mercury monitoring frequency to be reduced to 2/month when using Method 1631 analysis
also cannot be granted. A weekly monitoring frequency is consistent with all other Grade 4 facilities that have
mercury limits.
• Beryllium. The Division has removed the proposed effluent limit for beryllium. The facility reported that the
beryllium data used in the reasonable potential analysis was ultimately rejected due to QA/QC problems
discovered at the contract laboratory. The reported maximum detection (0.45 µg/L) was below accepted
practical quantitation limits (2 µg/L), and run without corresponding low-level standards. The laboratory has
acknowledged the QA/QC deficiencies and has corrected the problems beginning with effluent, .tatnpies
collected in April 2002. The Division concurs that the historical beryllium data set is unreliable. Therefore,
the beryllium limit was removed from the FINAL permit; however. the facility must continue quarterly effluent
monitoring for beryllium under the pretreatment LTMP program. This data will be reviewed again for
reasonable potential analysis at the next permit renewal.
• Ammonia/Summer Season. The FINAL permit includes both summer and winter limits for ammonia. similar
to the previous permit. Summer limits are more stringent than winter limits. The facility requested that the
month of April be designated as a "winter month" rather than "summer month" for ammonia, based on the
contention that wastewater temperatures are still low in April. The Division cannot concur with this request
at this time. The definition of "Summer Period" is defined in state regulations [15A NCAC 2B.0404 (c)) as April
1- October 31. Therefore, such a request would require a variance to a state rule. Requirements that must
be met in order to be eligible for a variance are located in General Statute 143-215(e), which include proving

that I) the discharge will not endanger human health or safety; and 2) compliance with the rule from which
the variance is sought cannot be achieved by application of best available technology found to be economically
reasonable, and would produce serious hardship without equal or greater benefits to the public.
• Ammonia/Weekly Limit. The DRAFT permit included ammonia limits based on monthly average limits only.
Subsequent to the DRAFT permit, a DWQ Ammonia Permitting Policy (dated October 15, 2002, and available
on the NPDES website) was approved by EPA Region 4, and is now being implemented in NPDES permits.
The ammonia policy addresses EPA concerns about the need for both monthly average as well as weekly
average permit limits for ammonia (N -b as N). For municipal facilities with monthly average ammonia limits,
a multiplier of 3 will be used to establish weekly average limits. The multiplier was derived from performance
data for eight municipal facilities. This FINAL permit implements the ammonia policy with the addition of
weekly average ammonia limits of 6.0 mg/L (summer) and 12.0 mg/L (winter).
• Cyanide PQL. The facility requested that the NPDES permit quantitation level for cyanide be designated as 20
µg/L, based on a cyanide study conducted by the City of Winston-Salem. The Division cannot concur with
this request. The Winston-Salem study was a site -specific determination, and results may not be applicable
to wastewater from the Greensboro facility. However, the Division will consider results of any site -specific
PQL study that the facility may perform in the future. Based on recent discussions with US EPA, a practical
quantitation level (PQL) of 10 µg/L was agreed upon, and is considered achievable by many contract
laboratories. For compliance purposes, all values below 10 µg/L (both detects and non -detects) will be
considered "zero."
• Adverse Weather. The facility requested that the adverse weather/dangerous stream sampling provisions
provided in state regulations (15A NCAC 2B.0505 (c)(4)1 be included in the FINAL permit. In response. this
language has been added to the bottom of the effluent sheet.
• Daily Definition. The facility requested that the definition for "Daily" sampling be included in the FINAL
permit. The state definition provided in 15A NCAC 2B.0503 (5) states that "Daily" means every day on which
a wastewater discharge occurs except Saturdays, Sundays, and legal holidays unless otherwise specified by
the Director. This definition has been added to the bottom of the effluent sheet.
• Total Metals. EPA commented on the DRAFT permit that metals should be specified as 'Total" in the effluent
sheet. This change has been incorporated into this FINAL permit.
• Treatment Components. The facility provided updated information on the wastewater treatment upgrades,
which has been incorporated in the Supplement to Permit Cover Sheet.
• Renewal Requirements. Please note that the U.S. EPA changed the NPDES permit application requirements
(per 40 CFR 122) for municipal facilities, effective August 1, 2001. EPA Forms 1 and 2A must be used for
your next permit renewal application, and additional analyses will be required. Any data submitted cannot be
over 4 1 years old. The new application requirements include:
Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application.
Samples must be representative of the seasonal variation in the discharge. The new PPA
requirements are included in Part D of EPA Form 2A.
A Conduct four chronic toxicity tests for an organism other than Ceriodaphnia and submit results with
your renewal application. The tests should be conducted quarterly. with samples collected on the
same day as your current toxicity test. Contact the Aquatic Toxicology Unit at [phone] for
guidance on conducting the additional tests.
• Pretreatment Data. Please include all future Pretreatment LTMP effluent data in the applicable monthly
Discharge Monitoring Reports.
The following items that appeared in the DRAFT permit remain in this FINAL permit:
• ! Phased Effluent Sheets. Effluent sheets for the current permitted flow of 30 MGD, and the phased 40 MGD
effluent sheet which will become effective after construction to 40 MGD is completed, currently projected for
2003.
• Nutrient Limits. Please note that this facility discharges to nutrient sensitive water (NSW) and already has TP
Units of 2 mg/L as a result of the NSW strategy. In 1997 the Clean Water Responsibility Act (House Bill 515)
was enacted. with the intent to strengthen the control of nutrients from all discharges to NSW waters.
Facilities permitted to discharge > 500,000 gallons per day, and any new or expanding facilities, are subject to
nutrient limitations for total nitrogen and total phosphorus according to House Bill 515 requirements. The
nutrient limitations are effective January 1, 2003, unless a compliance extension was received and approved
by the Division. Since an extension was approved, the HB 515 nutrient limits will be deferred until results of
a nutrient response modeling effort are completed. Please note that modeling results may result in limits
lower than those mandated by House Bill 515.
• Nutrient Monitoring. Increase in effluent nutrient monitoring frequency from monthly to weekly.
• Nutrient Reopener. Delete Special Condition H, Nutrient Reopener, since permit reopener language is already
present in the boilerplate (Part II, Section B. 13)
• Chronic Toxicity. Update the chronic toxicity test language, which was revised in 1999 to include different
follow-up procedures upon a test failure.

Issuance of NPDES Permit NC0047384

• Instream Monitoring. Instream monitoring requirements have been waived as long as the permittee maintains
membership in the Upper Cape Fear River Basin Association, which conducts instream monitoring in the
upper basin.
Reasonable Potential Analysis/Limits. Maintain effluent limits and weekly monitoring for cyanide, and add
effluent limits and weekly monitoring for mercury. Both of these compounds showed reasonable potential to
exceed applicable water quality standards/criteria. Conversely, delete the effluent limits for selenium and
fluoride based on lack of reasonable potential. Effluent monitoring for selenium is also deleted, and reduced
to 2/Month for fluoride. Delete the effluent limits for cadmium, and reduce effluent cadmium monitoring
from weekly to 2/Month. Instream monitoring for cadmium has also been deleted, based on lack of instream
detections (all upstream and downstream values reported as < 2 µg/L from 1/99-5/00). Finally, maintain
same effluent monitoring as last permit for copper and zinc. Both compounds showed reasonable potential to
exceed state action levels, but per Action Level Policy no limits are necessary since the facility has been
compliant with its chronic toxicity test limit.
• Permit Expiration. Extend the permit expiration date to June 30, 2006.
Please note that the receiving stream (South Buffalo Creek) is listed as an impaired water under Part 5 in North
Carolina's 303(d) list. The entire stream is listed as biologically impaired due to unknown causes. The receiving
stream is also listed in Part 4 for ammonia, with the facility upgrade expected to result in achievement of the
instream ammonia criteria. Instream data will continue to be evaluated. If there is noncompliance with permitted
effluent limits and degradation of South Buffalo Creek can be attributed to the facility, then additional mitigative
measures may be necessary.
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 a demand is made, this permit shall be final and binding.
This permit is not transferable except after notice to the Division. The Division may require modification or
revocation and reissuance of the permit. 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, please contact Tom Belnick at telephone number (919) 733-

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A (3). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly 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: Environmental Sciences Branch
North Carolina Division of Water Quality
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.

NC0047384: (T.Z.Osborne/South Buffalo)
EPA Comment:- on pg. 2 of your cover letter, Renewal Requirements,
bullet 2, line 1,- would you add "chronic" after "four", to ensure that
acute tests
aren't conducted? (same comment4pplies to NC0024325)
NC Response: Will do.
EPA Comment:- re the 303(d) language on pg. 3 of your cover letter, I'm
a little confused. The creek is listed for ammonia, but the facility is
expanding to 40 MGD and the ammonia limits are the same as at 30 MGD.
How does going to 40 MGD from 30 MGD at the same ammonia limits clear up
the existing impairment, as indicated in Part 4 of NC's 303(d) list?
Seems to me the limits would need to be more stringent, since ammonia
toxicity is a conc-based effect.
NC Response: In the 1995 permit issuance, the facility had phased
limits of 20/30/40 MGD, with NH3-N limits of 3.0/6.0 mg/1
(summer/winter) at 20 MGD, and 2.0/4.0 mg/1 (summer/winter) for the
phased 30/40 MGD upgrades. The facility was re -rated to 24 MGD on
5/5/2000, with NH3-N limits of 2.5/5.0 mg/1 (summer/winter). The 2000
303(d) list stated that the NH3-N limits would be revised lower at the
next upgrade (to 30 MGD). The facility completed this upgrade on
6/1/2001, at which time the more stringent 2.0/4.0 mg/1 (summer/winter)
limits kicked in. These limits were considered BAT for large
municipals. The ammonia limits are the same for both the 30/40 MGD
flows, since the change in the dilution factor for this
effluent -dominated stream is minimal (1.05 versus 1.03). As indicated,
we will continue to evaluate instream ammonia data to evaluate whether
additional measures are needed.
EPA Comment:- why are the TRC limits 18 ug/1, instead of 17 ug/1?
NC Response: The TRC limit is a chronic WQ-based limit using s7Q10
dilution, which amounts to the minimal dilution factor (1.05 and 1.03)
times the chronic action level of 17 ug/1, which rounds up to 18 ug/1
for both flows. If no limit was warranted, we would place the acute
criteria of 28 ug/1 as the limit.
NC0024325: (North Buffalo)
EPA Comment: - on pg.3 of your cover letter, Re•- al Requirements,
bullet 2, line 1- would you add "chronic" of -r "four", to ensure that
acute tests
aren't conducted?
NC Response: Will do.
EPA Comment:- on the permit lim s pg, "PH" should be "pH".
NC Response: Will do.
EPA Comment:- shouldn't t.- cyanide daily max limit be 22 ug/1, not 23
ug/1?
NC Response: •od catch. Will do.

Re: Greensboro TZ Osborne (South Buffalo), NC0047384
Hi Marshall- we talked a little about this but it was still on my
backburner. Subsequently, Dave met here last week (4/17/02) with some of
the EPA staff (Beverly, Scott, Roosevelt) and there was some discussion of
this permit. Dave said EPA agreed that the CN TMDL should not be an issue,
since the stream is not listed as impaired for cyanide. My question- based
on this recent EPA input, can I dismiss the CN TMDL as no longer relevant
for this receiving stream, since it is not listed as impaired for cyanide?
Thanks.

1. In the RPA that was provided, a number of metals were reported as
zeros - Se, Fe, As, Pb, Ag. Were the detection limits for these
sufficiently sensitive?
2. The RPA shows that there is RP for Cu and Zn and the fact sheet
states that there were 4 WET test failures in the 1997-2001 period.
Did some WET test failures occur in 2001 such that NC's new strategy re
the need for Cu and Zn limits was triggered?
3. "PH" should be "pH".
4. In both parts A.1 and A.2, the table says "TSR", but footnote below
says "TSS". These need to be consistent.
5. Are you planning to specify all metals as "total"?
6. There is no weekly average limit for NH3. We are discussing this
issue with Dave.
7. There is a TMDL for South Buffalo Creek that EPA approved on
9/16/97. The WLA of that TMDL states:
"cyanide 6.9 #/day. (allowable concentration of 20.8 ug/l. 40 MGD
design flow. 7Q10 flow of stream is 2.1 cfs)".
How are the draft permit's cyanide daily maximum limits of 22 ug/1
consistent with the assumptions of this WLA?

PROJECT NOTES
Summary
• This is a permit renewal for a major POTW serving a population of 205,000. The old permit contained
phased limits of 20/30/40 MGD. During the last permit round, the facility upgraded and rerated to 24
MGD, and recently completed an upgrade and expansion to the 30 MGD phased flow with new limits
effective 6/ 1 /01. Expansion to the final 40 MGD phase is anticipated by 2003, and an Authorization to
Construct for the final phase was issued 2/5/01.
• For the period June 2000-May 2001, the facility's monthly average flow ranged from 17 to 22 MGD. The
facility is currently averaging 4.8 MGD industrial and 15.2 MGD domestic wastewater. The facility operates
Page 3
Version: June 16, 2003

• NPDES PERMIT FACT SHEET City of Greensboro- T.Z.Osborne
Page 4 NPDES No. NC0047384
a full pretreatment program with quarterly effluent monitoring. There are currently 28 SIUs, including
facilities subject to federal categorical pretreatment limits for OCPSF, textile, metal finishing, electroplating,
electrical and electronic components, and copper forming. The facility recently lost up to 2.6 MGD of textile
wastewater in the first-half of 2001, but subsequently gained a 1.0 MGD wastewater discharge from Cone
Mills in June 2001, which previously discharged directly to North Buffalo Creek. The facility also receives
peak flows from the Greensboro North Buffalo Creek facility for treatment. Sludge is treated at the facility
by incineration.
• The facility discharges to South Buffalo Creek, which then discharges to Buffalo Creek>Reedy Fork>Haw
River>Jordan Lake. South Buffalo Creek is an effluent -dominated stream, with the Greensboro discharge
representing 96% of the instream waste concentration. South Buffalo Creek is listed in the Draft 303(d) list
in Part 5 for biological impairment. The stream use rating for South Buffalo Creek is PS (partially
supporting) to NS (not supporting). South Buffalo Creek had Poor water quality based on both fish and
benthos samples, while further downstream on Reedy Fork there is slight improvement to a Fair benthos
rating. The receiving stream is also classified as Nutrient Sensitive Water (NSW), and direct dischargers are
subject to nutrient limitations imposed by House Bill 515.
• The City of Greensboro has developed a Phase I NPDES stormwater program that will start to address
problems associated with urban runoff, which also has a severe impact on the water quality of portions of
South Buffalo Creek. The City and Clean Water Management Trust Fund (CWMTF) are building a 20-acre
regional stormwater wetland on South Buffalo Creek to enhance sediment removal, reduce pollutant loads,
and improve aquatic habitat in the 12-square mile urbanized watershed. Finally, the city is slip -lining old
sewer lines to minimize the impacts of infiltration and inflow.
Permit Limits Development
• Application. The permit renewal application was received on 7/30/2000, approximately 11 months prior to
the permit expiration date of 6/30/01.
• Permit Modifications. On 8/18/00 the permit was modified to extend the permit expiration date to 6/30/01
in order to align the subbasin renewal schedule. On 5/30/00 a Phase III Upgrade and rerating of facility to
24 MGD was completed. On 2/25/98 a permit mod increased permitted flow to 22 MGD, and provided for a
new total cyanide quantition level of 10 ug/1.
• Coalition Monitoring. Facility became a member of the Upper Cape Fear River Basin Association (UCFRBA)
in 2000. Instream monitoring requirements have been waived since 4/6/00 as long as facility maintains
membership in the UCFRBA. The UCFRBA collects one upstream sample (at Old US Hwy 70) and one
downstrean sample (at SR2821) near the discharge.
• Flow. The facility recently completed construction to the 30 MGD phased design flow, with limits becoming
effective 6/ 1 /01. The 30 MGD phased effluent sheet included new limits for TRC, as well as a change from
BOD to CBOD effluent limitations. Expansion to the final 40 MGD phased flow is projected at 2003.
• Conventional Parameters. There are no proposed changes in effluent limits for CBOD, NH3, TSS, Fecal,
TRC, or DO for the 30/40 MGD phased effluent sheets.
• Nutrients. The NSW Strategy has already mandated effluent TP limits of 2 mg/1. In 1997, HB 515 set
additional requirements on NSW waters, specifically TN load limits based on 5.5 mg/1, with an
implementation date of 1 / 1 /03. The City of Greensboro was one of nine facilities to request and receive a
compliance extension, under the condition that a calibrated nutrient response model be prepared for the
Jordan Lake watershed. Nutrient limits will ultimately be based on the model results, which are due in
April 2002.
• Metals. Based on results of the reasonable potential analysis (RPA), limits have been added for beryllium
and mercury, and maintained for cyanide. Limits were deleted for cadmium and fluoride. The previous
permit included effluent limits for cadmium as well as instream monitoring. However, review of instream
data shows no instream violations of the cadmium WQS for the past 18 months. Therefore, effluent
monitoring for cadmium was reduced to 2/month and instream monitoring for cadmium was deleted. The
facility plans to incorporate clean sampling techniques over this permit cycle, which should help to reduce
data variability and the potential for false positives.
• Water Quality Limited Parameters: CBOD, NH3, TRC, TP, cyanide, mercury, beryllium.
DMR Data.
• Effluent Chemistry Data. For the period 6/00-5/01, average monthly values ranged from 17-22 MGD (flow);
2-10 mg/1 (BOD); <0.1-3 mg/1 (NH3); 3-9 mg/1 (TSS); 5-60 org/100m1 (fecals); 3-12 mg/1 (TN); and 0.5-4.6
mg/1 (TP). The max TRC concentrations ranged up to 920 ug/1; however, these will now be limited to 18
ug/1 under the phased 30 MGD effluent sheet.
• Effluent Toxicity Data. The facility has generally been compliant with its chronic toxicity test limit, passing
17 of 21 tests at 90% effluent concentration between 1997-2001.

• Instream Data. Evaluation of summer instream data shows some DO values below the WQS of 5 mg/1 at
both the upstream and downstream stations during summer 1999, but instream DO values were >5 mg/1
during summer 2000 measurements. The discharge has resulted in measured decreases in downstream
DO of >1 mg/1 on some occasions, so summer instream data will continue to be evaluated for potential DO
impacts. There is no dominant trend for instream fecal data, while conductivity values are usually greater
at the downstream stations. The facility joined the UCFRB Monitoring Coalition in April 2000.
• Compliance Data. In calendar year 2000, the facility reported 1 monthly average violation for ammonia, 3
weekly average violations for cyanide, and 1 weekly average violation for cadmium. Between 1 / 1 /95-
10/31/00, the facility was assessed $1,072 for limits violations. There are currently no active SOCs.
WLA Data.
• The last WLA was prepared in 1995. The facility has an instream waste concentration of 96% (at 30 MGD)
and 97% (at 40 MGD).
Winston Salem Region Data.
• The WSRO conducted a Compliance Evaluation Inspection on 10/25/00. The plant was well maintained
and all components were operating satisfactorily.

Hi Marshall- I'm sending you the revised NPDES permits (without maps) for the subject facilities, since
you reviewed the drafts. The Fact Sheet Addendums detail the changes made since the draft permits
were noticed. These permits were on a back -burner as we resolved several issues (ammonia, mercury),
and the permittee was also investigating problems with their commercial lab which affected limits
development. I'm also including two rounds of comments received from the permittee, which were the
only comments received aside from EPA. Let me know if you have any comments/questions on the
proposed changes. Thanks.

RE: NPDES Draft Peri#NC0047384
City of Greensboro T. Z. Osborne POTW
Dear Mr. Belnick and Mr. Goodrich,
This purpose of this correspondence is to document the City of Greensboro Water
Resources Department's comments on the draft NPDES Permit for the T. Z. Osborne
Wastewater Treatment Facility. We request a meeting to further discuss these comments
and additional supporting information with DWQ staff. The comments are as follows:
Mercury and Beryllium Limits
The City of Greensboro requests the opportunity to conduct a special study on mercury
and beryllium before NPDES permit limits are imposed for these parameters. Please note
that the City of Greensboro has not previously used "clean metals techniques" for any
metals sampling and analyses. The current analyses are conducted on aliquots of the
daily 24-hour composite samples collected by our automatic samplers. Mercury was
detected in only one of the 14 T. Z. Osborne effluent samples analyzed and the one
detected value [6.24 ug/1] was near the detection limit of 0.2 ug/1. Currently all mercury
and beryllium analyses for the T. Z. Osborne POTW are conducted by a commercial
laboratory and within the past year, the Upper Cape Fear River Basin Association
QA/QC Committee discovered QA/QC problems at this laboratory. We would like the
opportunity to conduct clean metals analysis and split sample analyses to determine if the
mercury and/or beryllium are actually present in the effluent.

P.O. Box 3136 • Greensboro, NC 27402-3136 • www.ci.greensboro.nc.us • [phone] • TTY# 333-6930

November 16, 2001 Letter to Mr. Belnick and Mr.Goodrich — Page 2
We propose to conduct the metals study over a 12-month period to ensure that all weather
[summer/winter limits], seasonal industrial discharge changes and various POTW
operating conditions have been assessed. As you are probably aware, there are currently
no "clean metals" sampling techniques for composite samples and only a handful of
laboratories in the country can conduct true "clean metals" analyses. None of these
laboratories have sought certification by the State of North Carolina. We would like to
discuss these issues with the DWQ NPDES Section as well as the DWQ Laboratory
Section in the initial planning stage of our study.
In addition to the effluent clean metals analyses study, the City of Greensboro
Pretreatment Section would concurrently investigate any potential significant sources of
mercury and beryllium. Our proposed study would include both the North Buffalo and
the T. Z. Osborne POTWs and would include metals other than mercury and beryllium
for clean sampling and analyses.
The City of Greensboro has also conducted additional beryllium and mercury analyses on
the North Buffalo and T. Z. Osborne effluents since receiving the draft NPDES permits.
This data is currently being compiled and will be submitted prior to the requested
meeting with DWQ.
Winter/Summer Limits for Ammonia -Nitrogen
We request that April be designated as a "winter month" for the T. Z. Osborne ammonia -
nitrogen NPDES permit limits. Nitrification [the conversion of ammonia nitrogen to
nitrate and nitrite] is a biological process and, as such, is subject to metabolic rate
changes when the temperature of the incoming wastewater changes. The purpose of the
NPDES summer/winter limits is to reduce the ammonia limit during the months when the
receiving stream temperature is highest, since stream dissolved oxygen levels are
inversely related to temperature. Like the receiving stream, the incoming POTW
wastewater temperature is also dependent in large part on the ambient temperature. April
ambient temperatures are still quite cold. The incoming wastewater temperature does not
increase substantially enough to be considered a summer month and the receiving stream
temperatures are still low enough to allow winter permit limits.
Cyanide Quantitation Level
We request that the NPDES permit quantitation limit for cyanide be designated as 20 ug/1
based on the special cyanide study conducted by the City of Winston-Salem, North
Carolina.
Adverse Weather/Dangerous Sampling Conditions Provision
We request that the adverse weather/dangerous sampling conditions language contained
in the State regulations be included in the T. Z. Osborne NPDES permit conditions.

November 16, 2001 Letter to Mr. Belnick and Mr.Goodrich — Page 3
Definition of "Daily"
We request that the definition of "daily" included in 15A NCAC 2B .0503 [Definitions]
be included in the T. Z. Osborne [and North Buffalo] NPDES permit boiler plate or on
the permit limits page.
The City of Greensboro appreciates the opportunity to comment on this permit. We look
forward to meeting with State staff to expedite timely reissuance of the T. Z. Osborne
NPDES permit.
If you have any questions or need additional information, please do not hesitate to contact
me at 336-375-2229 or by email at [e-mail]

PROJECT NOTES
Summary
• This is a permit renewal for a major POTW serving a population of 205,000. The old permit contained
phased limits of 20/30/40 MGD. During the last permit round, the facility upgraded and rerated to
24 MGD, and recently completed an upgrade and expansion to the 30 MGD phased flow with new
limits effective 6/ 1 /01. Expansion to the final 40 MGD phase is anticipated by 2003, and an
Authorization to Construct for the final phase was issued 2/5/01.
• For the period June 2000-May 2001, the facility's monthly average flow ranged from 17 to 22 MGD.
The facility is currently averaging 4.8 MGD industrial and 15.2 MGD domestic wastewater. The
facility operates a full pretreatment program with quarterly effluent monitoring. There are currently
28 SIUs, including facilities subject to federal categorical pretreatment limits for OCPSF, textile, metal
finishing, electroplating, electrical and electronic components, and copper forming. The facility
recently lost up to 2.6 MGD of textile wastewater in the first-half of 2001, but subsequently gained a
1.0 MGD wastewater discharge from Cone Mills in June 2001, which previously discharged directly to
North Buffalo Creek. The facility also receives peak flows from the Greensboro North Buffalo Creek
facility for treatment. Sludge is treated at the facility by incineration.
• The facility discharges to South Buffalo Creek, which then discharges to Buffalo Creek>Reedy
Fork>Haw River> Jordan Lake. South Buffalo Creek is an effluent -dominated stream, with the
Greensboro discharge representing 96% of the instream waste concentration. South Buffalo Creek is
listed in the Draft 303(d) list in Part 5 for biological impairment. The stream use rating for South
Buffalo Creek is PS (partially supporting) to NS (not supporting). South Buffalo Creek had Poor water
quality based on both fish and benthos samples, while further downstream on Reedy Fork there is
slight improvement to a Fair benthos rating. The receiving stream is also classified as Nutrient
Sensitive Water (NSW), and direct dischargers are subject to nutrient limitations imposed by House
Bill 515.
• The City of Greensboro has developed a Phase I NPDES stormwater program that will start to address
problems associated with urban runoff, which also has a severe impact on the water quality of
portions of South Buffalo Creek. The City and Clean Water Management Trust Fund (CWMTF) are
building a 20-acre regional stormwater wetland on South Buffalo Creek to enhance sediment
removal, reduce pollutant loads, and improve aquatic habitat in the 12-square mile urbanized
watershed. Finally, the city is slip -lining old sewer lines to minimize the impacts of infiltration and
inflow.
Permit Limits Development
• Application. The permit renewal application was received on 7/30/2000, approximately 11 months
prior to the permit expiration date of 6/30/01.
• Permit Modifications. On 8/18/00 the permit was modified to extend the permit expiration date to
6/30/01 in order to align the subbasin renewal schedule. On 5/30/00 a Phase III Upgrade and
rerating of facility to 24 MGD was completed. On 2/25/98 a permit mod increased permitted flow to
22 MGD, and provided for a new total cyanide quantition level of 10 ug/l.
• Coalition Monitoring. Facility became a member of the Upper Cape Fear River Basin Association
(UCFRBA) in 2000. Instream monitoring requirements have been waived since 4/6/00 as long as

facility maintains membership in the UCFRBA. The UCFRBA collects one upstream sample (at Old
US Hwy 70) and one downstrean sample (at SR2821) near the discharge.
• Flow. The facility recently completed construction to the 30 MGD phased design flow, with limits
becoming effective 6/ 1 /01. The 30 MGD phased effluent sheet included new limits for TRC, as well
as a change from BOD to CBOD effluent limitations. Expansion to the final 40 MGD phased flow is
projected at 2003.
• Conventional Parameters. There are no proposed changes in effluent limits for CBOD, NH3, TSS,
Fecal, TRC, or DO for the 30/40 MGD phased effluent sheets.
• Nutrients. The NSW Strategy has already mandated effluent TP limits of 2 mg/1. In 1997, HB 515
set additional requirements on NSW waters, specifically TN load limits based on 5.5 mg/1, with an
implementation date of 1 / 1 /03. The City of Greensboro was one of nine facilities to request and
receive a compliance extension, under the condition that a calibrated nutrient response model be
prepared for the Jordan Lake watershed. Nutrient limits will ultimately be based on the model
results, which are due in April 2002.
• Metals. Based on results of the reasonable potential analysis (RPA), limits have been added for
beryllium and mercury, and maintained for cyanide. Limits were deleted for cadmium and fluoride.
The previous permit included effluent limits for cadmium as well as instream monitoring. However,
review of instream data shows no instream violations of the cadmium WQS for the past 18 months.
Therefore, effluent monitoring for cadmium was reduced to 2/month and instream monitoring for
cadmium was deleted. The facility plans to incorporate clean sampling techniques over this permit
cycle, which should help to reduce data variability and the potential for false positives.
• Water Quality Limited Parameters: CBOD, NH3, TRC, TP, cyanide, mercury, beryllium.
DMR Data.
• Effluent Chemistry Data. For the period 6/00-5/01, average monthly values ranged from 17-22 MGD
(flow); 2-10 mg/1 (BOD); <0.1-3 mg/1 (NH3); 3-9 mg/1 (TSS); 5-60 org/10Orn1 (fecals); 3-12 mg/1 (TN);
and 0.5-4.6 mg/1 (TP). The max TRC concentrations ranged up to 920 ug/1; however, these will now
be limited to 18 ug/1 under the phased 30 MGD effluent sheet.
• Effluent Toxicity Data. The facility has generally been compliant with its chronic toxicity test limit,
passing 17 of 21 tests at 90% effluent concentration between 1997-2001.
• Instream Data. Evaluation of summer instream data shows some DO values below the WQS of 5
mg/1 at both the upstream and downstream stations during summer 1999, but instream DO values
were >5 mg/1 during summer 2000 measurements. The discharge has resulted in measured
decreases in downstream DO of >1 mg/1 on some occasions, so summer instream data will continue
to be evaluated for potential DO impacts. There is no dominant trend for instream fecal data, while
conductivity values are usually greater at the downstream stations. The facility joined the UCFRB
Monitoring Coalition in April 2000.
• Compliance Data. In calendar year 2000, the facility reported 1 monthly average violation for
ammonia, 3 weekly average violations for cyanide, and 1 weekly average violation for cadmium.
Between 1 / 1 /95-10/31 /00, the facility was assessed $1,072 for limits violations. There are currently
no active SOCs.
WLA Data.
• The last WLA was prepared in 1995. The facility has an instream waste concentration of 96% (at 30
MGD) and 97% (at 40 MGD).
Winston Salem Region Data.
• The WSRO conducted a Compliance Evaluation Inspection on 10/25/00. The plant was well
maintained and all components were operating satisfactorily.

Subject: Greensboro WWTPs- Pretreatment LTMP Data
Date: Mon, 13 May 2002 16:01:24 -0400
From: Tom Belnick <[e-mail]>
To: [e-mail]
Hi Martie- I double-checked the 1999/2000 LTMP data that I used to do
the reasonable potential analysis for both facilities for the draft
permit. The detections of mercury were back in September 1999, and the
detections of beryllium occurred back in December 2000. Thus, all these
samples will be outside the 6 month holding time and not worth
re -analyzing, even if the samples were still available.
I'd like to take a look at the data collected since then. Can you send
me the LTMP data for Hg/Be for 2001 and 2002 (if already collected).
Also, can you include the 2001/2002 data for selenium. In the 1999-2000
dataset, there were some detections of selenium reported at the lab
quantitation level, so I'd like to see if they were all non -detects
since then. Thanks.

Subject: Renewal of NPDES Permit Number NC0047384
City of Greensboro T. Z. Osborne Facility -Guilford County
Dear Mr. Weaver,
The City of Greensboro hereby requests renewal of NPDES Permit Number
NC0047384 issued to the T. Z. Osborne Water Reclamation Facility. Enclosed
please find 3 copies [1 original and 2 copies] of the required documentation
requested in your recent correspondence.
The T. Z. Osborne Water Reclamation Facility is currently under upgrade to
discharge 30 MGD which is different than the last permitting request in 1995.
[The current permitted capacity is 24 MGD.] At that time, the request was for 20
MGD. Projected completion date for this upgrade is January 2001.
If you require any additional information or have any questions, please feel free to
contact me at 336-373-2055.
Sincerely,
LA/144t/i
Allan Williams
Director of Water Resources

Part VI: Facility Description
Present Operating Status:
Currently the TZO WRF is operating at a permitted capacity of 24 MGD until the upgrade to 30 MGD is
completed. The following is a narrative of the liquid process. Please find attached the current design liquid
train.
Narrative: Consists of screening, grit removal, primary settling, single stage activated sludge
nitrification, final settling, tertiary treatment, chlorination and cascade — type post aeration. Chemical
addition for phosphorus removal is also included.
Potential Facility Changes:
As indicated in the cover letter the current upgrade will be completed in January 2001. Two other upgrades
are currently being performed in conjunction with the 30 MGD. One is an installation of generator backup
and the other is installation of a third centrifuge. Design is currently underway to upgrade the TZO WRF
from 30 MGD to 40 MGD.
Sludge Management Plan:
The sludge treatment process includes gravity sludge thickening, sludge dewatering using belt filter presses
or centrifuges and sludge stabilization using incinerators. Final disposal of incinerator ash is in the city
sanitary landfill. An alternative for sludge stabilization is dewatering and disposal at an approved site.
