Subject: Issuance of NPDES Permit NCO020354
Town of Pittsboro WWTP
Chatham County
Dear Mr. Misenheimer:
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 141-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Prote Aion Agency dated May 9, 1994 (or as
subsequently amended).
This final permit includes no changes from the draft permit sent to you on October 25, 2006. You are
reminded of the following terms within this permit that are different from the one currently effective:
• A weekly average limit for ammonia has been added to the permit. Since December 2002, the
Division has been adding daily maximum limits for ammonia to permits with monthly average limits
in order to conform to federal NPDES regulations.
• Monitoring requirements have been added pursuant to the Division's Cape Fear River Basin
permitting strategy, which is primarily concerned with the discharge of nutrients in the Jordan Lake
watershed. These new requirements include monitoring/reporting for:
Total Kjeldhal Nitrogen (TKN)
Nitrates + Nitrites (NO2 + NO3)
Total Monthly Flow
Total Nitrogen Load (Monthly and Annual Loading)
Total Phosphorous Load (Monthly and Annual Loading)
The Town is currently monitoring for all of these parameters per the requirements of the existing
permit. The new requirements will call for different manipulations and/or displays of the data on
monthly reports.
• New narrative conditions [Sections A. (3) — A. (6)] have been added to address various aspects of
nutrient issues relevant to this discharge.

• A Total Residual Chlorine (TRC) daily maximum limit has been added. Since the issuance of the
existing permit, the North Carolina Environmental Management Commission has adopted rules
that establish a water quality standard for TRC. However, the condition within the permit remains
that TRC will only have to be monitored if chlorine is added as a disinfectant or used elsewhere in
the process.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, the Coastal Area Management Act or any other Federal or
Local governmental permit that may be required.

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 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed during the months of, March, June, September, and December. 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 H 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 TEP3B for the Chronic Value. Additionally, DWQ Form AT -3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 chemicallphysical 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/or 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 initial monitoring.

A. (3.) PERMIT RE -OPENER: SUPPLEMENTARY NUTRIENT MONITORING
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in Title 15A of
the North Carolina Administrative Code, Subchapter 0211, specifically, 15A NCAC 02H.0 I 12(b)(1) and
02H.01 14(a), and Part 11, 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:
Monthly TN (or TP) Load (lb/mo) = TN (or TP) x TMF x 8.34
where:
TN (or TP) _ the average Total Nitrogen or (Total Phosphorus) concentration
(mg/L) 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.
A. (5.) TOTAL PHOSPHOROUS LIMITS IMPLEMENTING THE TOTAL MAXIMUM
DAILY LOAD (TMDL) FOR ROBERSON CREEK
A Total Phosphorous summer effluent limit consistent with the requirements of the TMDL for Roberson
Creek will be included in the permit issued to this facility for the next permit cycle and subsequent
permit cycles if and as long as the facility continues to discharge into Roberson Creek. As of the issue
date of this permit, the prospective summer limit at 0.75 MGD for Total Phosphorous will be 1.5 lbs/day
(an approximate 0.25 mg/L concentration equivalent). The Town will be expected take necessary
actions to ensure it will be compliant with such a limit by the expiration date of this current permit if the
discharge remains in Roberson Creek.
Please refer to the final Total Maximum Daily Load (TMDL) publication for Roberson Creek.

wastewater treatment system for the Town of Pittsboro, it appears that no adverse effect on water quality will
occur to the existing public water supply intakes.
We concur with the issuance of this permit provided this facility is operated and maintained properly;
the stated effluent limits are met, prior to discharge; and the discharge does not contravene the designated water
quality standards.
If we can be of further assistance, please contact Michael L. Douglas, P.E., at 919-791-4200.

Dear Mr. Misenheimer:
Alan W. Klimek, P E. Director
Division of Water Quality
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following changes from the terms contained in your current permit:
• A weekly average limit for ammonia has been added to the permit. Since December 2002, the
Division has been adding daily maximum limits for ammonia to permits with monthly average
limits in order to -conform to federal NPDES regulations.
• Monitoring requirements have been added pursuant to the Division's Cape Fear River Basin
permitting strategy, which is primarily concerned with the discharge of nutrients in the Jordan Lake
watershed. These new requirements include monitoring/reporting for:
Total Kjeldhal Nitrogen (TKN)
Nitrates + Nitrites (NO2 + NO3)
Total Monthly Flow
Total Nitrogen Load (Monthly and Annual Loading)
Total Phosphorous Load (Monthly and Annual Loading)
The Town is currently monitoring for all of these parameters per the requirements of the existing
permit. The new requirements will call for different manipulations and/or displays of the data on
monthly reports.
• New narrative conditions [Sections A. (3) — A. (6)] have been added to address various aspects of
nutrient issues relevant to this discharge.

Town of Pittsboro WWTP Draft Permit
p.2
A Total Residual Chlorine (TRC) daily maximum limit has been added. Since the issuance of the
existing permit, the North Carolina Environmental Management Commission has adopted rules
that establish a water quality standard for TRC. However, the condition within the permit remains
that TRC will only have to be monitored if chlorine is added as a disinfectant or used elsewhere in
the process.
Please submit any comments to me no later than 30 days following your receipt of the draft permit.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in December 2006, with an
effective date of February 1, 2007.

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, March, June, September, and December. 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 TBP3B for the Chronic Value. Additionally, DWQ Form AT -3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Section

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/or 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 initial monitoring.

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 (lb/mo) = TN (or TP) x TMF x 8.34
where:
TN (or TP) _ the average Total Nitrogen or (Total Phosphorus) concentration
(mg/L) 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.
A. (5.) TOTAL PHOSPHOROUS LIMITS IMPLEMENTING THE TOTAL MAXIMUM
DAILY LOAD (TMDL) FOR ROBERSON CREEK
A Total Phosphorous summer effluent limit consistent with the requirements of the TMDL for Roberson
Creek will be included in the permit issued to this facility for the next permit cycle and subsequent
permit cycles if and as long as the facility continues to discharge into Roberson Creek. As of the issue
date of this permit, the prospective summer limit at 0.75 MGD for Total Phosphorous will be 1.5 lbs/day
(an approximate 0.25 mg/L concentration equivalent). The Town will be expected take necessary
actions to ensure it will be compliant with such a limit by the expiration date of this current permit if the
discharge remains in Roberson Creek.
Please refer to the final Total Maximum Daily Load (TMDL) publication for Roberson Creek.

A. (6.) TOTAL PHOSPHOROUS COMPLIANCE PLANS
By January 1, 2009, the Town of Pittsboro will submit a plan prepared by a professional engineer
documenting how it intends to satisfy the Total Maximum Daily Load (TMDL) that has been established
for Roberson Creek and/or Total Phosphorous permit limits imposed upon the Town of Pittsboro
WWTP based upon the TMDL or other nutrient management strategies for the Cape Fear River Basin.
The plan should include an analysis of projected growth for the Town and projected future wastewater
needs along with detailed discussion of how the Town plans to meet any needs for additional capacity
and remain iri compliance with Water quality regulations.. -The report -should -discuss any plans for
expansion of the WWTP, potential relocation(s) of the outfall and the effects these decisions may have
on both permitting issues and the actual water quality of the receiving stream. This report shall be
submitted to:

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12 -month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
