Permit NCO064378
A. (3) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
L Monthly. TN Load (pounds/month) = TN x TMF x 8.34
Where:
TN = average TN concentration (mg/L) of the composite samples collected during the month
TMF = Total Monthly Flow of wastewater discharged during the month (MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the
calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in
the discharge monitoring report for that month and shall report each year's annual
results (pounds/year) in the December report for that year.
A. (4) ANNUAL LIMITS FOR TOTAL NITROGEN
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse
River basin are annual limits and are applied for the calendar year.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN
Load limit in this Permit if:
i. the Permittee's annual TN Load is less than or equal to said limit, or
ii. the Permittee is a Co-Permittee Member of a compliance association.
c. The TN Load limit in this Permit (if any) may be modified as the result of allowable
changes in the Permittee's TN allocation.
i. Allowable changes include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; regionalization; and other transactions approved by
the Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application,
the Division will modify the permit as appropriate and in accordance with state and
federal program requirements.
iii. Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for
changes proposed for the following calendar year.
iv. Application shall be sent to:
NCDWQ / NPDES Programs
Attn: Neuse River Basin Coordinator
1617 Mail Service Center
Raleigh, NC 27699-1617
d. If the Permittee is a member and co-permittee of an approved compliance association, its
TN discharge during that year is governed by that association's group NPDES permit and
the TN limits therein.
i. The Permittee shall be considered a Co-Permittee Member for any given calendar year
in which it is identified as such in Appendix A of the association's group NPDES
permit.
ii. Association roster(s) and members' TN allocations will be updated annually and in
accordance with state and federal program requirements.

Permit NCO064378
iii. If the Permittee intends to join or leave a compliance association, the Division must be

as appropriate and in accordance with state and federal program requirements.
(2) Membership changes in a compliance association become effective on January 1
of the year following modification of the association's permit.
e. The TN monitoring and reporting requirements in this Permit remain in effect until
expiratidn of this Permit and are not affected by the Permittee's membership in a
compliance association.
A. (5) TOTAL NITROGEN ALLOCATIONS
a. The following table lists the Total Nitrogen f m allocation(s) assigned to, acquired by, or
transferred to the Permittee in accordance with the Neuse River nutrient management rule
(T15A NCAC 02B .0234) and the status of each as of permit issuance. For compliance
purposes, this table does not supercede any TN limit(s) established elsewhere in this
permit or in the NPDES permit of a compliance association of which the Permittee is a Co-
Permittee Member.

Permit NCO064378
A. (6) 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 90.0%.
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 & 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: 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, iriclude 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 (Al)
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 the receiving stream, this permit may be re -opened and modified to include alternate
monitoring requirements or limits.
If the Permittee .monitors any pollutant more frequently then required by this permit, the results of
such monitoring shall be included in the calculation & reporting of the data submitted on the DMR &
all AT Forms submitted.
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.

YES— This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
/ name/ownership changes).
YES v This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan),
Conventional WTP, 303(d) listed, toxicity testing, instream monitoring,
compliance concerns, phased limits). Basin Coordinator to make case -by -
case decision.
YES_ This permit CANNOT. BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS, etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
