111. Certification Statement:
I Todd Taylor, P.E. 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 11 plus all attached planning assessment addendums for which I
am the responsible party. Signature of this fonn certifies that the receiving collection system or treatment
works has adequate capacity to transport and treat the proposed new wastewater.

PLANNING ASSESSMENT ADDENDUM (PAA)
Submit a planning assessment addendum for each pump station listed in Section 11 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-
215.67(a) which prohibits the introduction of any waste in excess of the capacity of the waste disposal
system.

Instructions for Flow Tracking 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 facilfty'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 aviz. 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 facili , MGD Equals [d + e +
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 11
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).
Finn 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.

Plannin2 Assessment Addendum Instructions
Submit a planning assessment addendum for each pump station listed in Section 11 where available capacity is < 0.
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 Q. 0 1 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 cqpacity of the pgmp station by October 2015. Inclusion of this proposed cgpital project as a condition
of this Flow Tracking/Acceptance for Sewer Extension Permit Application elevates this project's priority fo
funding and construction to be implemented ahead of the activation of obligated, not yet tributau flows in amounts
that exceed the firm pump station cgpacities identified in Section 11 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.

Response to NCDEQ Submittal #1 Review Comments
BA Project #122012.00
Dear Ms. Wilson,
This letter is written to provide a point -by -point response to NCDEQ Submittal #1 Review
Comments, which we received following the staff's first review for the above referenced
project. Below are the comments we received on April 3rd, 2024, each followed by our
response in bold type.
1. DWR needs Todd Taylor's email address on the application as he has signed the
permit ([e-mail] can be in addition to Todd's email, but not in place of).
Ref Part 1.3. of the application. DWR has to make sure the person who signs the
application is copied on any correspondence.
Response: Email address updated.
2. Regarding Part VI.2.- although you indicate that this is older infrastructure - is the
size of the gravity sewer that this project will connect to not known?
Response: Size of the gravity sewer added to application.
1 1 don't think for this public piece that Part VI.2. should be checked regarding
the Developer's Oper Agreement (as this is necessary and covered in the
private entity and this will be a public gravity line). At least this is my
understanding from what you have submitted.
Response: Agree and this has been corrected.
4. Part VI.6 should be checked yes or no.
Response: Application corrected.
5. Part VI.7 - flow can be updated to use 75 GPD/bedroom for new build (based
on recently passed legislation 10/23). Related to this - you have included flow
in both the public and private portions. Either the private permit or the public

permit must indicate the receiving flow - not both (as that would double
count what the actual flow going to the treatment facility is).
Response: Flow updated.
6. Part V1.8. this needs to reflect the project flow (0 GPD if this will be counted
in the private portion; or the full flow if this will be counted in this public
portion). Just make sure this is explained in the narrative.
Response: Full flow has been added to the application.
7. There appears to be a stream through the site - please reconfirm that this
project (and the private portion) will comply with the Jordan Lake buffer rules
(and reconfirm that a 401/404 is not needed.
Response: The proposed work is outside buffers and will comply with
Jordan Lake Buffer rules. No 401/404 permits required.
8. I'm not sure if the narrative matches what is described in Part V1.7.
Response: The total units (107) and linear footage (1,393 LF) match on
narrative and application.
9. Please provide a basic sewer flow diagram (similar to that attached). It should
indicate the public portion, the private portion and where this ties into the
existing downstream sewer.
Response: We highlighted our Utility Overview showing the public portions
of the project shown in green.
Please don't hesitate to call me should you have any questions or if you require additional
information.
Yours very truly,
