Dear Mr. Robinson:
Nov 14 2023
Hazen and Sawyer is pleased to submit two (2) copies of the Big Branch 2 Pump Station
application package to request issuance of a Sewer Permit for the pump station and the
associated gravity sewer and force main.
Project Description
The Big Branch 2 Pump Station (BB2PS) is designed to serve a portion of the Big Branch Basin.
The pump station's service area will receive flow from future developments in southern Apex
and pump these flows to the Western Wake Water Reclamation Facility (WWWRF).
Since the BB2PS will only serve future developments, no flow will be introduced to the system
by this project. Additional flow will be requested as needed for future developments.
Encroachments/Permits
Encroachments and permits in progress include the following:
• Sedimentation and Erosion Control
• Town of Apex Site Plan Permit
• 401/404 Stream Permit
• NCDOT Driveway Permit and Encroachment Agreement
Items Included in Application Package
The following lists all the items included with this application package:
1) Check for $600

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.

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).
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 H 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 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 uvarade with funding planned in Jul.} 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 vet 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.

Hi Brian —
I've performed an initial review on this application. If you could answer/clarify the following:
1. Please indicate the basin name etc. on Part IXA. The project is located in the Cape Fear Basin. Attached is the
update page of the Application with this modification. Please let us know if the signature page needs to be
updated.
1

Please provide the 404/401 number for this project (Part IX.5.). Or confirmation of receipt of project proposal
from the ACOE. 404/401 application was submitted and is currently under review. The USACE Action ID is SAW-
2024-00257.
Can you and/or Apex give a timeline of development and when flow will be needed along this line? (I am aware
of how quickly the area is growing, but we need this information as part of the record for the application). DWR
is hesitant to approve "dry lines" without some consideration of timeframe. Written justification should be
provided as to exactly why they cannot wait to build the sewer until closer to when it's actually needed. Also,
information regarding when the extension/future permitting to incorporate flow is expected to be made, along
with expected design flow. Developments in parts of the basin are currently underway. A second pump station
(BB1PS) is being designed and constructed as part of a separate project which will tie into our proposed force
main on the BB2PS site. This pump station will serve these new developments and is expected to receive flow
upon its completion and will convey flows to Western Wake WRF using the force main as soon as it is available.
Development in the BB2 basin for the pump station in this application (BB2PS) is currently unknown but is
expected to begin shortly after the completion of the pump station, depending on market conditions.
4. We'll likely put some language regarding for "construction only" in the permit. I'll consult with our central office
folks about what may be appropriate. Noted. As stated in our response on question 3, the force main will be
placed into service very soon after completion.
5. Essentially this entire project - gravity sewer, PS, and force main will connect directly at Western Wake WRF?
Yes, the force main will discharge into an existing connection at the WWWRF's Headworks.
Please provide the above information within 30 days. If additional information/corrected application is not received
within 30 days, your application will be returned, and you will need to resubmit along with the fee (ref. 15A NCAC
02T.0107(e)(2)J.
Feel free to contact me if you have any questions. (And likely easiest to reach me via email initially).

Hi Brian —
A few questions before I wrap this up.
1. It looks like the 401 application has been withdrawn? And they are working towards on IP? Here's the link in
our document storage. Let me know if you have information on the resubmittal (this is not a requirement, I
realize this is moving forward — but if you happen to know if it's been submitted yet).
https://edocs.deq.nc.gov/WaterResources/DocView.aspx?id=3223823&dbid=0&repo=WaterResources
1

The original submittal was a Pre -Construction Notification application for Nationwide Permit 58 and associated
general 401 Water Quality Certification. The project proposes to impact an area that was previously designated as
mitigation for impacts in an EIS and therefore requires a Standard Permit through the US Army Corps of
Engineers. We are currently working on developing the Standard Permit application package for submittal to
USACE and DWR for authorization under Sections 404 and 401, respectively, of the Clean Water Act. It will be
submitted this week.
2. We received the above maps for Big Branch 1. 1 can't attach this to your application submittal as it is
another firm's work. Would you provide something similar?
Please see the attached maps.
didn't realize these were dual force mains. Could you document how the pump station will work to ensure
redundancy? I'd like to see some description ensuring the capacity of 3 pumps (and that with a dual path —
these aren't isolated duplex systems; I'm unable to determine that based on the documentation. I assume
they are not, but I'd like you to provide a statement to that effect).
The pumps for BB2PS are being designed to convey the full built out flow of the pump station with 3 pumps (3
duty/1 standby) in the dual force mains with BB1 PS flow manifolding into the dual force mains and using both
mains as well. The pumps are being sized to initially convey the 4.3 mgd firm capacity with the Phase 1 capacity
(6.5 mgd) of BB1 PS. When BB1 PS is upgraded in the future for buildout flows, the pumps in BB2PS are selected
such that they will only need an impeller change to continue to convey a form capacity of 4.3 mgd with Buildout
flows from BB1 PS. Both force mains will be needed to convey the buildout flows for the basin, but they will be a
number of interconnections that will allow the Town to repair/replace portions of the mains if needed while
maintaining close to the firm capacities of each pump station.
If you have any questions and/or you'd like to set up a teams call, just let me know. Thanks much.

Hi Brian —
was trying to wrap up this draft permit and get it to Mike for signature this week.
On review of the application (I'm sorry I just realized this — I should have caught it upon first review). You indicated
(via Part IX.3) that the project will not comply with the separation requirements for wetlands. I did not see in the
application package that you indicated the areas of non-conformance? For fast track purposes, I will be fine with
an outline or highlight on the map you recently provided, of the approximate areas of nonconformance. And a
narrative stating that you folks will meet the alternative design criteria specified by 15A NCAC 02T .0305(g)(5) and
the attachment (draft policy):
