In response to comments received July 21 from Joe Pearce, Utility Division Manager, please find
enclosed the following corrected pages for the County's NPDES permit, issued July 9, 2010:
• Supplement to Permit Cover Sheet. The facility description is revised to reflect a single 'Sludge
lagoon' rather than multiple 'Sludge lagoons,' and the three references to projected service dates
now specify '2011' instead of '2010.'
• Standard Conditions, Part IV, Section C, Municipal Control of Pollutants from Industrial Users.
Two grammatical/ typographical errors have been corrected:
• Subparagraph 2.b.5. - 'Heat in amount which will may inhibit' becomes 'Heat in amount
which will inhibit'

Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from industries
using the municipal system may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water
quality standards.
2. Prohibited Discharges
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional
Office. Any information shall be provided orally within 24 hours from the time the Permittee became
aware of the circumstances. A written submission shall also be provided within 5 days of the time the
Permittee becomes aware of the circumstances. The written submission shall contain a description of the
discharge, the investigation into possible sources; tire period of the discharge, including exact dates and
times; and if the discharge has not ceased, the anticipated time it is expected to continue; and steps taken
or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance.
With regard to the effluent requirements listed in Part I of this permit, it may be necessary for the Permittee to
supplement the requirements of the Federal Pretreatment Standards (40 CFR, Part 403) to ensure compliance
a. Under no circumstances shall the Permittee allow introduction of pollutants or discharges into the waste
treatment system or waste collection system which cause or contribute to Pass Through or Interference as
defined in 15A NCAC 2H.0900 and 40 CFR 403. [40 CFR 403.5 (a) (1)]
Under no circumstances shall the Permittee allow introduction of the following wastes in the waste
treatment or waste collection system [40 CFR 403.5 (b)]:
Pollutants which create a fire or explosion hazard in the POFW, including, but not limited to,
wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees
Centigrade using the test methods specified in 40 CFR 261.21;
Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH
lower than 5.0, unless the works is specifically designed to accommodate such discharges;
Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
4. Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow
rate and/or pollutant concentration which will cause Interference with the POTW;
Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will
cause Interference or Pass Through;
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity
that may cause acute worker health and safety problems;
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of
effluent introduced into the POTW, and (2) any anticipated impact that may result from the change of the
quantity or quality of effluent to be discharged from the POTW.
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other

Subject: NPDES Permit Modification
Permit NC0026051
Durham County Triangle WWTP
Durham County
Consistent with the Director's October 1, 2009, letter of intent to modify NPDES permits affected by the
Jordan Reservoir Nutrient Management Strategy rules and in consideration of public comments on the
subsequent draft permit modifications, the Division is forwarding herewith the revised NPDES permit
for the Durham County Triangle WWTP. This permit modification 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.
The Division received the County's comments on the draft permit during the initial public comment
period. We also received comments from several permittees, including the County, regarding the
standard permit conditions (Parts II, III, and IV) in the draft permits. The final permit includes the
following changes in addition to those proposed in the draft:
• Nitrogen Optimization. The Nitrogen Optimization condition has been deleted. The County
correctly noted that this requirement applies only to pre-BNR facilities.
• Standard Conditions. Jeff Poupart of the Point Source Branch has worked with other programs
within the Division and with EPA Region 4 staff to evaluate and address the comments received.
The final permit includes a newly revised version of the standard permit conditions. We
appreciate your patience in this matter and regret any inconvenience this delay may have caused.
Implementation of Total Phosphorus (TP) Limits. The Jordan Reservoir Wastewater Discharge
Requirements (T15A NCAC 02B .0270) established annual mass phosphorus limits for fourteen
treatment facilities, to become effective with calendar year 2010. Thus, even though the effective date of
this permit modification is August 1, 2010, the new limits became effective January 1,2010, by rule and
apply to calendar year 2010 in its entirety.

A.(3.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortahty 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
February, May, August, and November. 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:
NCDENR/ 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 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 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.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to tire 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.

the burden of proof in any enforcement proceeding.
(2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take
enforcement action against a Permittee for a bypass as provided in any current or future system-wide
collection system permit associated with the treatment facility.
(3) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse effects,
if the Permit Issuing Authority determines that it will meet the three conditions listed above in
Paragraph c. (1) of this section.
(1) An upset occurred and that tire Permittee can identify the cause(s) of the upset;
(2) The Permittee facility was at the time being properly operated; and
(3) The Permittee submitted notice of the upset as required in Part II. E. 6. (b) of this permit.
(4) The Permittee complied with any remedial measures required under Part II. B. 2. of this permit.
(1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take
enforcement action against a Permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime.
This condition is not satisfied if adequate backup equipment should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which occurred during normal
periods of equipment downtime or preventive maintenance; and
(C) The Permittee submitted notices as required under Paragraph b. of this section.
Power Failures
The Permittee is responsible for maintaining adequate safeguards (as required by ISA NCAC 2H.0124) to
prevent the discharge of untreated or inadequately treated wastes during electrical power failures either by
means of alternate power sources, standby generators or retention of inadequately treated effluent.
Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to
prevent any pollutant from such materials from entering waters of the State or navigable waters of the United
States. The Permittee shall comply with all existing Federal regulations governing the disposal of sewage
sludge. Upon promulgation of 40 CFR Part 503, any permit issued by the Permit Issuing Authority for the
utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to incorporate
applicable requirements at 40 CFR 503. The Permittee shall comply with applicable 40 CFR 503 Standards for
the Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the regulation, even
if the permit is not modified to incorporate the requirement. The Permittee shall notify the Permit Issuing
Authority of any significant change in its sludge use or disposal practices.
5. Upsets
a. Effect of an upset [40 CFR 122.41 (n) (2)]: An upset constitutes an affirmative defense to an action brought
for noncompliance with such technology based permit effluent limitations if the requirements of
paragraph b. of this condition are met. No determination made during administrative review of claims
