- Permit NCO064378
A. (3.) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. 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
H. 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.) TOTAL NITROGEN ALLOCATIONS
a. The following table lists the Total Nitrogen (TN) 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.

and shall be subject to the public review process afforded such modifications under state and federal rules.

Permit NCO064378
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 90.0%.
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 TGP313 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, 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 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.
