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
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) ANNUAL LIMITS FOR TOTAL NITROGEN
(a) TN limits for NPDES dischargers in the Neuse River basin are as prescribed in the
basin's Nutrient Management Strategy rule for wastewater treatment facilities, T15A
NCAC 2B .0234.
(b) The Permittee's TN discharge is governed by this Permit unless the Permittee is a
member and co-permittee of an approved compliance association, in which case its TN
discharge is governed by the association's group NPDES permit and the limits therein.
(c) TN limits for NPDES dischargers in the Neuse River basin are annual, calendar -year
limits. All such limits in effect on January 1 of a given year remain in effect for the
entire calendar year. Changes in TN limits become effective on January 1 of the year
following permit modification and remain in effect for the full year. Similarly, changes in
membership in a compliance association become effective on January 1 of the year
following the change and remain in effect for the full year.
(d) For any given calendar year, the Permittee shall be in compliance with the annual TN
Load limit in this Permit if:
(1) the Permittee's annual TN Load is less than or equal to said limit, or
(2) the Permittee is a Member of a compliance association and a Co-Permittee to the
association's group NPDES permit.
(e) The Permittee's effective TN limit (if any) may change due to changes in its TN allocation
or membership changes in a compliance association.
(1) The Permittee may notify the Division and request a modification of this Permit to
incorporate allowable changes in its TN Load limit. 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.
(2) If the Permittee intends to join or leave a compliance association, the Division must
be notified of the proposed change.
(3) Upon receipt of timely and proper notification, the Division will modify the affected
permit(s) as necessary to incorporate the allowable changes in TN limits or to reflect
the change in membership.
a. The Division must receive notification no later than August 31 for changes
proposed for the following calendar year.
b. Notification shall be sent to:
NC DENR / DWQ / NPDES Unit
Attn: Neuse River Basin Coordinator
1617 Mail Service Center
Raleigh, NC 27699-1617
(0 For the purpose of permit compliance, an association's Co-Permittee Members in a
calendar year (and the Permittee's membership status) shall be as defined in its group

Permit NCO064378
NPDES permit. The roster and the members' TN allocations will be updated annually
and in accordance with state and federal program requirements.
(g) The TN monitoring and reporting requirements in this Permit remain in effect until
expiration of this Permit and are not affected by the Permittee's membership in a
compliance association.
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 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, 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. -
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.

Re: NC006437, Willowbrook WWTP Permit modification to accept radiological waste from
softener and quantity of waste.
Dear Toya: Carolina Water Service Inc. of North Carolina currently wishes to install one
radiological removal well systems in our Willowbrook subdivision. The total waste discharged
to the Willowbrook WWTP collection system by this well systems will be 6672 gallons per
month.
Should the Willowbrook Waste Treatment Facility exceed our radiological limits several options
would be implemented.
The frequency of the regeneration cycle would be increased. This would reduce the
concentration of the waste entering the collection system.
A storage tank would be installed at the well site to collect the waste. A flow reduction valve
would be installed and continuously add a small quantity of waste to the collection system.
Both these changes to our method of disposal would reduce waste concentrations to the
treatment system.
Sincerely
Kerry Walton
Area Manager
