Dear Mr. Drew:
John E, Skvarla, III
Secretary
Issuance of NPDES Permit NCO047384
Renewal and Expansion
T.Z. Osborne WWTP
Guilford County
Facility Class IV
Division personnel have reviewed and approved your application for expansion and 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 October 15, 2007 (or as subsequently amended).
Please note that the receiving stream is listed as an impaired waterbody on the North
Carolina 2012 303(d) Impaired Waters List for copper and zinc. Addressing impaired waters
is a high priority with the Division, and instream data will continue to be evaluated. If there
is noncompliance with permitted effluent limits and stream impairment can be attributed to
your facility, then mitigative measures may be required.
The following items are in response to the comment letter )received from the City of
Greensboro on March 21, 2014.
• The Cyanide limitation and footnote were removed from this pen -nit since the
effluent from the T.Z. Osborne WWTP did not show reasonable potential to violate
state Water Quality Standards (WQS). However, the Division recognizes that the
City of Greensboro's effluent quantitation limit for cyanide shall be 20 µg/L and
levels reported below 20 µg/L shall be considered zero for Pretreatment Long Term
Monitoring Program purposes.
• The Fact Sheet was revised to include the nutrient calculations used for the modified
allocations.
• Condition A.(3) in the permit has been modified to clarify that the TN and TP combined
delivered load limits will apply to the T.Z. Osborne WWTP at a permitted flow of 40 MGD
once the North Buffalo Creek WWTP permit is rescinded and until the expansion is

completed. Additionally, paragraph (a.) under Section A. (I.) has been revised to reference
condition A.(3.) where the combined delivered limitations for TN and TP are described.
Per the City's request footnote #4 was added under Section A.(2.) to state that the ammonia -
nitrogen limitations do not become effective until the average plant flow for the calendar
year is greater than or equal to 36 MGD. The footnote was modified to include a statement
that when the City of Greensboro reports that the annual average flow is greater than or
equal to 36 MOD with their December DMR, the City shall include a cover letter with the
report stating that the ammonia -nitrogen limits in Section A.(2.) are now effective.
The following item was added to the permit in response to comments from DWR
Public Water Supply Regional and Central Office stafff.
A special condition was added_ under Section A. (13.) stating that this permit may be
reopened and modified in the future to include 1,4-dioxane monitoring and/or
reduction measures, if the wastewater discharge is identified as contributing to
violations of surface water quality standards.
As identified previously, the renewal permit contains the ffollo�ving significant changes ffronn
your current permit:
• The permit expiration date has been changed to June 30, 2019 to allow five years before
permit renewal. The Division may change the expiration renewal to coincide with Basin
renewals when staffing workloads allow for shorter renewal periods.
• The City of Greensboro's request for Monitoring Frequency Reductions for fecal coliform,
total suspended solids, CBOD5, and ammonia -nitrogen was reviewed. Reduced monitoring
frequencies for fecal coliform, total suspended solids, and CBOD5 were permitted and a
reduction from daily monitoring to twice per week was made for all three parameters in
Section A:(1.). Upon expansion, the City of Greensboro will sample these parameters daily
and may revert back to twice per week sampling for the parameters for which no permit
limit violation occurs. See Section A.(2.) and footnote #13. Ammonia -nitrogen effluent
sampling results did not meet the Guidance requirements to allow for a sampling reduction.
® The requirement to begin reporting discharge monitoring data electronically, no later than
March 30, 2015 (within 270 days of the NPDES Permit effective date), using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been
added to your final NPDES permit. [See Special Condition A.(12.)] For information on
eDMR, registering for eDMR and obtaining an eDMR user account, please visit the
following web page:

stream reclassification for South Buffalo Creek from C; NSW to WS-V; NSW. See the
Supplement to Permit Cover Sheet.

• Cyanide, cadmium, nickel, and fluoride effluent sampling results did not show reasonable
potential to violate Water Quality Standards. Limits and monitoring requirements for all
four parameters were removed from the permit.
• Effluent sampling data for selenium showed reasonable potential to violate Water Quality
Standards. Monthly monitoring and limitations for selenium were added to the permit.
• Copper and zinc sampling results showed reasonable potential to violate WQS, however,
they are action level parameters and monitoring is set in conjunction with toxicity test
results. T.Z. Osborne is passing its toxicity tests so limits are not necessary. Both
parameters remain in the permit and sampling was reduced from monthly to quarterly in
accordance with the NPDES Monitoring Frequency memo dated July 15, 2010.
• In accordance with the 2012 Statewide Mercury TMDL, the requirement to perform a
Mercury Minimization Plan (MMP) was added to the permit. See MMP Special Condition
A.(11.). Please note that the MMP shall be developed by December 29, 2014 (within 180
days of the NPDES Permit effective date). A sample MMP was developed through a
stakeholder review process and has been placed on the Division website for guidance at:
http://portal.ncdenr.org/web/M/swp/ps/npdes.
• Five years of mercury data was reviewed and all the annual averages were less than the
WQBEL and the TBEL. The mercury limitation was removed and monitoring shall continue
as part of the City's Effluent Pollutant Scans.
• Section A.(2.) was added to include limitations and monitoring requirements when T.Z.
Osborne WWTP is expanded to 56 MGD.
• Footnote number 2 in Section A.(3) was revised to recognize Session Laws 2011-394
(HB 119) and 2013 -3 95 (SB515) which extends the compliance date to 2021 if an
ATC is acquired before December 31, 2019 for upgrades needed to meet the TN
allocation.
• In accordance with Federal Regulations 40 CFR 122 a Total Nitrogen Reduction
Schedule containing annual milestones outlining the steps the City of Greensboro
will take to comply with the Jordan Lake Wastewater Discharge Rule (15A NCAC
02B .0270), as modified by North Carolina Session Laws 2011-394 (HB119) and
2013-395 (SB515), was added under Special Condition A.(4.).
• Revisions were made to Sections A.(7.) and A.(9.) to recognize nutrient allocation
and loading calculation changes required with the expansion. Please review these
Sections carefully. Note the numbers in the allocation Tables in Section A.(7.) have
been rounded and the Totals were determined using additional significant digits. All
delivered loads were converted to discharge loads using T.Z. Osborne's transport
factors.
• Some of the wording has changed in Section A. (5.), Chronic Toxicity Permit Limit,
please review each paragraph carefully.
• Section A. (6.) on the Effluent Pollutant Scan now designates the three years in which the
scans are to be performed — 2016, 2017, and. 2018. Please review this condition.
• Section A. (10.) Nitrogen Optimization Plan was added to confirm that the City of
Greensboro will continue to evaluate its treatment facilities and operational processes to

make reasonable efforts to reduce nitrogen discharges until process improvements are
completed as stated in its nitrogen optimization plan dated 2/11/2010.
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
Resources 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.

A.(5.) 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, quartedy monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent
versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure (Revised- December
2010) or subsequent versions. The tests will be performed during the months of January, April, July, and
October. These months signify the first month of each three month toxicity testing quarter assigned to the
facility. Effluent sampling for this testing must be obtained during representative effluent discharge and
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 -December 2010) 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, DWR Form AT-3 (original) is to be
sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section 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 Water
Sciences Section 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. Assessment of toxicity compliance is based on the toxicity
testing quarter, which is the three month time interval that begins on the first day of the month in which
toxicity testing is required by this permit and continues until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Resources 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.

A.(10.) NITROGEN OPTIMIZATION PLAN
On February 17, 2010 the City of Greensboro submitted a plan to optimize the reduction of nitrogen in
its wasterwater discharges. It is expected that the City of Greensboro will implement these measures
and continue to evaluate its treatment facilities and operational processes to make reasonable efforts to
reduce nitrogen discharges until process improvements are completed.
A.(11.) MERCURY MINIMIZATION PLAN (MMP)
The permittee shall develop and implement a Mercury Minimization Plan (MMP) during this permit
term. The MMP shall be developed by December 29, 2014, and shall be available for inspection on -site.
A sample MMP was developed through a stakeholder review process and has been placed on the
Division website for guidance (ht!p://portal.ncdenr.org/web/­­wq/­`swp/ps/­npdes, under Model
Mercury Minimization Plan). The MMP should place emphasis on identification of mercury
contributors and goals for reduction. Results shall be summarized and submitted with the next permit
renewal.
A.(12.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)]
Beginning no later than March 30, 2015, the permittee shall begin reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet
application.
Monitoring results obtained during the previous month(s) shall be sununarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR),
permittees will be required to submit all discharge monitoring data to the state electronically using
eDMR and will be required to complete the eDMR submission by printing, signing, and submitting
one signed original and a copy of the computer printed eDMR to the following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
PART I, Page 15 of 18

Permit No. NCO047384
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1,1.1, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address
above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted
in writing to the Division for written approval at least sixty (60) days prior to the date the facility
would be required under this permit to begin using eDMR. Temporary waivers shall be valid for
twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted electronically
to the Division unless the permittee re -applies for and is granted a new temporary waiver by the
Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edrnr
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)]
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section
B. (11)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting
purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North Carolina's
eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following
