Please see enclosed two (2) sets of Fast -Track Applications (FTA 04-16) and an accompanying review
fee check of $480.00 for the subject project for your review and approval.
The proposed Gregory Village Subdivision is located at the intersection of NC 210 and Tripp Road in
the Town of Lillington, Harnett County, NC. We are seeking a permit to install a public sanitary
sewer extension to serve 112 proposed single-family and townhome residences.
The proposed sanitary sewer extension consists of 3,728 LF of 8" PVC and 813 LF of 8" DIP
extending off of an existing sanitary sewer main located along NC 210 South of the site. The
proposed sanitary sewer main will be public. The construction of this sanitary sewer extension is
projected to begin in Spring of 2021.
If you have any questions or need any additional information, please contact me at [phone].
Sincerely,
Thomas Spaulding, PE

III. Certification Statement:
I Ashley Wimberly certify to the best of my knowledge that the addition of
the volume of wastewater to be permitted in this project has been evaluated along the route to the
receiving wastewater treatment facility and that the flow from this project is not anticipated to
cause any capacity related sanitary sewer overflows or overburden any downstream pump station
en route to the receiving treatment plant under normal circumstances, given the implementation of
the planned improvements identified in the planning assessment where applicable. This analysis
has been performed in accordance with local established policies and procedures using the best
available data. This certification applies to those items listed above in Sections I and II plus all
attached planning assessment addendums for which I am the responsible party. Signature of this
form indicates acceptance of this wastewater flow.

PLANNING ASSESSMENT ADDENDUM (PAA)
Submit a planning assessment addendum for each pump station listed in Section II where Available
Capacity is < 0.
Pump Station (Name or Number):
Given that:
a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for
% and MGD of the Available Capacity (E) in Pump Station
; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately
MGD per year; and that
c. A funded Capital Project that will provide the required planned capacity, namely
is in design or under construction with
planned completion in ; and/or
d. The following applies:
Therefore;
Given reasonably expected conditions and planning information, there is sufficient justification to
allow this flow to be permitted, without a significant likelihood of over -allocating capacity in the
system infrastructure.
I understand that this does not relieve the collection system owner from complying with G.S. 143-

Instructions for Flow Tracking/Acceptance form (FTSE) and Planning Assessment Addendum (PAA)
Section I
a. WWTP Facility Name: Enter the name of the WWTP that will receive the wastewater flow.
b. WWTP Facility Permit #: Enter the NPDES or Non -Discharge number for the WWTP receiving the
wastewater flow.
c. WWTP facility's permitted flow, MGD: From WWTP owner's NPDES or Non -Discharge permit.
d. Estimated obligated flow not yet tributary to the WWTP, MGD: This includes flows allocated to other
construction projects not yet contributing flow to the collection system. Flows allocated through
interlocal agreements or other contracts not yet contributing flow to the collection system are also
included. For POTWs that implement a pretreatment program, include flows allocated to industrial
users who may not be using all of their flow allocation. Please contact your Pretreatment Coordinator
for information on industrial flow tributary to your WWTP.
As of January 15, 2008 the POTW should have reviewed flow allocations made over the last two years
and reconciled their flow records, to the best of their ability, so it is known how much flow has been
obligated and is not yet been made tributary to the WWTP, in accordance with local policies and
procedures employed by the reporting entity.
e. WWTP facility's actual avg. flow, MGD: Previous 12 month average.
f. Total flow for this specific request, MGD: Enter the requested flow volume.
g. Total actual and obligated flows to the facility, MGD Equals [d + e + f]
h. Percent of permitted flow used: Equals [(g / c)*100]
For example:
On January 15 a POTW with a permitted flow of 6.0 MGD, reported to the Regional Office that there
is 0.5 MGD of flow that is obligated but not yet tributary. The annual average flow for 2007 is 2.7
MGD. There is a proposed flow expansion of 0.015 MGD.
The first Form FTSE submitted after January 15, 2008 may have numbers like this:
c. = 6.0 MGD
d. = 0.5 MGD
e. = 2.7 MGD
f. = 0.015 MGD
g. = 3.215 MGD
h.=53.6%
The next Form FTSE may be updated like this with a proposed flow expansion of 0.102 MGD:
c. = 6.0 MGD
d. = 0.515 MGD
e. = 2.73 MGD
f. = 0.102 MGD
g. = 3.349 MGD
h. = 55.8 %
Each subsequent FTSE form will be updated in the same manner.

Section II
List the pump station name or number and approximate pump station firm capacity, approximate design
average daily flow (A) approximate current average daily flow (B), and the obligated, not yet tributary flow
through the pump station (C) for each pump station that will be impacted by the proposed sewer extension
project. Calculate the total current flow plus obligated flow (D=B+C) and the available capacity (E=A-D).
Include the proposed flow for this project with other obligated flows that have been approved for the pump
station but are not yet tributary (C).
Firm capacity is the maximum pumped flow that can be achieved with the largest pump out of service as
per the Minimum Design Criteria.
Design Average Daily Flow is the firm capacity of the pump station divided by a peaking factor (pf) of not
less than 2.5.
If the available capacity (E) for any pump station is < 0, then prepare a planning assessment for that pump
station if the system has future specific plans related to capacity that should be considered in the permitting
process.

Planning Assessment Addendum Instructions
Submit a planning assessment addendum for each pump station listed in Section II where available capacity
is < O.
A planning assessment for Kaw Creek PS (see example data above) may be performed to evaluate whether
there is significant likelihood that needed improvements or reductions in obligated flows will be in place
prior to activating the flows from the proposed sewer extension project.
If the system decides to accept the flow based on a planning assessment addendum, it is responsible to
manage the flow without capacity related sanitary overflows and must take all steps necessary to complete
the project or control the rate of flow to prevent sanitary sewer overflows.
The planning assessment may identify a funded project currently in design or construction, or a planned
project in the future not yet funded but in a formal plan adopted by the system. The system should carefully
weigh the certainty of successful timely project completion for any expansion, flow management diversion
or infiltration and inflow elimination projects that are the foundation of a planned solution to capacity
tracking and acceptance compliance.
For example:
Given that:
a. The proportion and amount of obligated, not yet tributary flow accounts for 24 % and 0.080
MGD of the committed flow in Pump Station Kaw Creek; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.01
MGD per year; and that
c. A funded capital project that will provide the required planned capacity, namely
is in design or under construction with
planned completion in ; and/or
d. The following applies:
The master plan and ten year capital plan contain recommended scope and funding for a capital project
entitled Kaw Creek Pump Station upgrade with funding planned in July 2014. This project is planned to
add 0.100 MGD to the firm capacity of the pump station by October 2015. Inclusion of this proposed
capital project as a condition of this Flow Tracking/Acceptance for Sewer Extension Permit Application
elevates this project's priority for funding and construction to be implemented ahead of the activation of
obligated, not yet tributary flows in amounts that exceed the firm pump station capacities identified in
Section II above.
Therefore:
Given reasonably expected conditions and planning information, there is sufficient justification to allow
this flow to be permitted, without a significant likelihood of over -allocating capacity in the system
infrastructure.
