Subject Issuance of NPDES Permit
NC0047384
T.Z. Osborne WWTP
Guilford County
Dear Mr. Williams -
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as
subsequently amended).
This final permit includes the following major changes from the draft permit sent to you on
July 5, 2006:
1) The fluoride limit value was changed to 1.9 mg/L to correct an error.
2) Monitoring frequencies for Total Nitrogen, Nitrogen Species and Total Phosphorus were
reduced to weekly in accordance with the revised Permitting Strategy for the Cape Fear
River Basin.
3) An annual pollutant scan was limited to 3 times per permitting cycle to'be consistent with
the EPA requirements. However, the Division continues to recommend that a yearly analysis
be conducted so that the Division may have more data to evaluate for the next permit
renewal.
4) The Nutrient Controls Re -Opener language was changed to meet the Division's legal
requirements.
5) The'weekly average limit for nickel has been added to the permit. This limit is based on a
statistical analysis of the effluent data, monitoring for nickel has been increased to weekly.
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.

Permit NC0047384
A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
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 Section
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.

Permit NQ00473B4
A. (3) PERMIT RE -OPENER: NUTRIENT CONTROLS
Pursuant to N.C. Gen. Stat. Section 143-215.1 and the implementing rules found in Title 15A of the North Carolina
Administrative Code, Subchapter 2H, specifically, 15A NCAC 2H.0112(b)(1) and 2H.0114(a), and Part II sections B-12 and
B-13 of this Permit, the Director of DWQ may reopen this permit to require supplemental nutrient monitoring of the
discharge. The additional monitoring will be to support water quality modeling efforts within the Cape Fear River Basin,
and shall be consistent with a monitoring plan developed jointly by the Division and affected stakeholders.
A. (4) CALCULATION.OF MASS LOADS
a. The Permittee shall calculate monthly and annual TN (or TP) Loads as follows:
i. Monthly TN (or TP) Load (ib/mo) = TN (or TP) x TMF x 8.34
where:
TN (or = the average Total Nitrogen or (Total Phosphorus) concentration (mg/L)
TP) of the composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN (or TP) Load (lb/yr) = Sum of 12 Monthly TN (or TP) Loads for calendar year
b. The Permittee shall report monthly Total Nitrogen and Total Phosphorus results (mg/L and lb/mo) in the appropriate
discharge monitoring report for each month and shall report each year's results (lb/yr) with the December report for
that year.

Permit NC0047384
A. (5) EFFLUENT POLLUTANT SCAN
The Permittee shall perform an annual Effluent Pollutant Scan for all parameters listed in the attached table (using a
sufficiently sensitive detection level in accordance with 40 CFR Part 136). The Permittee shall perform 3 Effluent
Pollutant Scans prior to submitting the permit renewal application. Samples shall represent seasonal variations.

SUMMARY
This facility is a major municipal treatment plant operating in Guilford County that
serves 146,250. City has a separate sewer collection system. Facility has a permitted
flow of 40 MGD discharging into South Buffalo Creek. For the past 2 years annual
average flow varied within the range of 19.01-23.08 MGD. The facility has recently
completed expansion to 40 MGD. The City of Greensboro has 30 significant industrial
users and a full-scale pretreatment program. The permit will require the City to
continue to implement its existing pretreatment program.
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 95% of the instrearn
waste concentration. South Buffalo Creek is listed in the Draft 303(d) list in Part 5 for
biological impairment. 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.

07 / 02 / 03 - CN, NH3. The facility claims that they experience matrix interference and
most of their CN limit violations are false positives. Currently they are conducting
study to determine if matrix interference exists and their practical quantitation limit
should be increased to 20 lig/L.
A compliance evaluation inspection conducted on April 27, 2006 found that facility is
well maintained and properly operated.
INSTREAM MONITORING:
Instream monitoring is required for temperature, dissolved oxygen, fecal coliform, and
conductivity. The facility is a member of the Upper Cape Fear Monitoring Coalition,
and all their instream monitoring is conditionally waived for the duration of their
membership in the Coalition.
PROPOSED CHANGES:
•- Monitoring Frequencies: Monitoring frequencies for fluoride and cadmium have
been increased to weekly due to the implementation of the new permit limit.
In accordance with the Division's new Permitting Strategy for Cape Fear River Basin
the following changes have been made:
1. Monitoring frequencies for TN and TP were increased to 3/Week.
2. Monitoring for TKN and NO3-N + NO2-N was added to the permit.
3. Load monitoring for TN and TP was added to the permit.
4. Nutrient Controls Re -Opener condition was added to the permit.
5. Total monthly flow reporting was added to the permit.
• Limits: Based on Reasonable Potential Analysis, limits are being introduced for
fluoride and cadmium.
• Priority pollutant monitoring on an annual basis has been added to fulfill the
permit application requirement in the future.

Re: Comments on Draft NPDES Permit NC0047384
T. Z. Osborne WWTP-Guilford County
Dear Mr. Chemikov,
This purpose of this correspondence is to document the City of Greensboro Water Resources
Department comments on the draft NPDES Permit for the T. Z. Osborne Wastewater
Treatment Facility. The City of Greensboro comments are as follows:
Permit Cover Sheet
T. Z. Osbome Street Address
• The street address for the T. Z. Osbome facility is 2350 Huffine Mill Road. I
noted that you used the street address on the cover page of the North Buffalo
NPDES Permit and thought you might need the numerical address for the T. Z.
Osborne plant.
Supplement to Permit Cover Sheet
Item #1-Correction of List of treatment components
■ Please remove "alternate sludge stabilization" from the Sludge treatment units
listed.
Part A. (1) Effluent Limitations and Monitoring Requirements
Total Residual Chlorine Listing Correction
■ Total Residual Chlorine is listed twice under Effluent Characteristics, once
without a limit on line 9 and again with a limit on line 22. Please remove one of
the listings. We prefer you remove the one with the limit! However, we realize
that request may not be granted, as we assume line 9 was merely a clerical error.

T. Z Osborne Draft NPDES Permit [NC00473841 Comments Page 2
August 9, 2006 Correspondence to DWQ
Fluoride Limit and Monitoring Requirements
• Fluoride Reasonable Potential Analysis - Only one value reported since January
2002 [2.0 mg/1 on 5-19-2004] would have exceeded the proposed limit. Fluoride
testing is currently conducted by an outside commercial laboratory. We are
willing to take a fluoride limit and weekly monitoring for one year with the
provision that we may petition DWQ to have the limit removed at the end of that
year if the data indicates no reasonable potential exists for an exceedance of the
limit
• Fluoride Limit Value — The same incorrect value that was placed in the draft
North Buffalo permit has been placed in the draft T. Z. Osborne NPDES permit
As per our telephone conversation of 7-6-2006 concerning the North Buffalo
draft permit, please change/correct the fluoride limit from 1685.0 ug/1 to 1865.0
ug/1 and then convert the limit to milligrams per liter (mg/L). It is not possible to
measure micrograms per liter of fluoride to five significant figures. In addition,
the North Carolina water quality standard for fluoride is expressed as 1.8 mg/L,
not 1800.0 ug/l. Therefore, we request that the NPDES limit be expressed as 1.9
mg/L and reported accordingly. (Please note this is the same limit included in a
previous T. Z. Osborne NPDES permit originally issued by DWQ on November
1, 1991.)
Total Nitrogen and Total Phosphorus Monitoring Frequency
• We request that the total nitrogen and total phosphorus monitoring frequency
remain at once per week. In recent meetings (June 2006) concerning the Jordan
Lake reservoir, DWQ staff stated that lack of resources would prevent them from
conducting any additional modeling studies on nutrient response in Jordan Lake.
Therefore, we feel that increased monitoring of point source loading is not
warranted. If DWQ develops a specific modeling plan schedule and commits in
writing to conduct additional nutrient response modeling on Jordan Lake for the
purpose of determining the appropriate point source nutrient target loadings, we
will gladly conduct three times per week nutrient monitoring for the two year
period required to calibrate and validate a new nutrient response model.
• The NPDES permits of major dischargers to the Nutrient Sensitive Neuse River
and the Tar -Pamlico River basins contain once per week nutrient monitoring for
total phosphorus and total nitrogen. The same criteria should be used in the
Upper Cape Fear Basin.
• We attended the 7-7-2006 meeting in Graham between DWQ staff and Jordan
Lake watershed NPDES permittees to discuss the nutrient monitoring frequency
issue. We look forward to working together to develop a solution agreeable to
both parties.
• As recently requested by DWQ, a NPDES nutrient monitoring frequency
proposal will be submitted to Matt Matthews from all Jordan Lake Watershed
NPDES pern ittees. It is anticipated that this correspondence will be submitted
by the group on or before August 11, 2006.

T. Z. Osborne Draft NPDES Permit INC00473841 Comments -Page 3
August 9, 2006 Correspondence to DWO
Part A. (5) Effluent Pollutant Scan
■ Does DWQ propose that two -species bioassay analyses be conducted in
conjunction with each of the required annual Effluent Pollutant Scans? Form 2A
requires 3 pollutant scans and 4 two -species bioassay tests. Although the permit
cover letter states that the annual pollutant scan can be conducted concurrent with
toxicity testing, there does not appear to be any permit language in the draft
permit that outlines that requirement and there is no mention of two -species
whole effluent toxicity testing. Please provide additional information to clarify
this requirement.
• The DWQ annual pollutant scan permit condition exceeds the EPA requirement
We request that the permit condition be changed to the original EPA requirement
of three priority pollutant scans.
■ The draft permit cover letter from DWQ states that the annual pollutant scans can
be used "for the new renewal application required by the Environmental
Protection Agency". NPDES Form 2A states that only three scans are required
and that the data used can be "no more than four and one half years old".
Previous DWQ correspondence also used the 4.5 year window. However, the
document entitled "Instructions for completing Form 2A" published by EPA in
the Federal Register Wednesday, August 4,1999 contains the following
statement inAppendix A -Guidance for Completing the Effluent Testing
Information; All Treatment Works:
"All data provided in the application must be based on samples taken
within three years prior to the time of this permit application."
Please provide documentation that DWQ has determined, in conjunction with
EPA, that it is legally permissible to submit data that is more than 3 years old
on Form 2A.
A.(41 Calculation of Mass Loads
• Please provide DMR parameter code numbers for the Total Nitrogen and Total
Phosphorus monthly mass load calculations values, the Total Nitrogen and Total
Phosphorus yearly mass loading calculation values and the total monthly flow
values required to be reported on DMRs.
Thank you for the opportunity to comment on the draft T. Z. Osborne NPDES permit If you
