Subject:Issuance of NPDES Permit NCO061638
Amherst WWTP
Wake County
Class WW-2
Dear Mr. Lashua:
Division personnel have reviewed and approved your application for
renewal of the subject permit. Accordingly, we are forwarding the attached
NPDES discharge permit. This permit 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 (or as subsequently amended).
This final permit includes no major changes from the draft permit sent
to you on June 5, 2013.
Please note that Middle Creek is listed as an impaired waterbody on
the North Carolina 303(d) Impaired Waters List. Addressing impaired waters
is a high priority with the Division; instream data will continue to be
evaluated. If there is noncompliance with this permit's effluent limits and
stream impairment can be attributed to your facility, then mitigative
measures may be required.
If any parts, measurement frequencies or sampling requirements
contained in this permit are unacceptable to you, you have the right to an
adjudicatory hearing upon written request within thirty (30) days following
receipt of this letter. This request must be in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes,
and filed with the Office of Administrative Hearings (6714 Mail Service
Center, Raleigh, North Carolina 27699-6714). Unless such demand is made,
this decision shall be final and binding.

Permit NC0061638
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 Total Nitrogen concentration (mg/L) of the
composite samples collected during the month
TMF = Total Monthly Flow of wastewater discharged during the
month (MG/mo.)
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) 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

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 permits) 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:

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
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 02D .0234) and the status
of,each as of permit issuance. For compliance purposes, this table does
