Subject:
Dear Permittee:
Draft NPDES Permit NCO056618
Carolina Pines Estates WWTP
Grade WW-2 WPCS
Craven County
The Division has reviewed your request to renew the subject permit. Enclosed with this letter is a copy
of the draft permit for your facility. Please review this draft carefully to ensure your thorough
understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
y A reopener condition for all Neuse River discharge permits has been added at Part I. (A.) 6.
Electronic data submission requirements have been updated.
The segment of the Neuse River to which your facility discharges is listed as an impaired stream on
North Carolina's 303 (d) list. Currently, the stream does not meet all water quality standards. If the
limitations in the current permits for facilities discharging to this segment of the Neuse River do not
result in improved water quality, removal of discharges may be necessary for the health of the stream.
We will continue to monitor compliance at your facility. If noncompliance with your permit's effluent
limits is shown to be a direct cause of stream degradation to this segment of the Neuse River, the
Division will recommend removal of your facility's discharge.
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in
this draft document (cover, map, and Part I). The conditions are the same as in your current permit
except that agency and division names have been updated. The latest version is available at
https://bit.ly/3k5NFaL and can be viewed online or downloaded as a PDF file.
With this notification, the Division will solicit public comment on this draft permit by publishing a
notice in newspapers having circulation in the general Craven County area, per EPA requirements.
Please provide your comments, if any, to me at the e-mail address below no later than 30 days
after receiving this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit.

A. (3.) CALCULATION OF TOTAL NITROGEN LOADS
[G.S. 143-215.1(b)]
a. The permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (pounds/month) = TN x TMF a 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
[G.S. 143-215.1(b)]
(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
Page 5 of 10

Permit NCO056618
(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:

(f) 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 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.) TOTAL NITROGEN ALLOCATIONS
[G.S. 143-215.1(b)]
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 .0713) and the
status of each as of permit issuance. For compliance purposes, this table does not supersede 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.
