Entity Requesting Allocation: HensonFoley Design
Project Name for which flow is being requested: Watermark Office Building
More than one FTSE may be required for a single project if the owner of the WWTP is not responsible for all pump
stations along the route of the proposed wastewater flow.
I. Complete this section only if you are the owner of the wastewater treatment plant.
a. WWTP Facility Name: McDowell Creek WWTP
b. WWTP Facility Permit #: NC0036277
All flows are in MGD
c. WWTP facility's permitted flow 12.0
d. Estimated obligated flow not yet tributary to the WWTP 0.404
e. WWTP facility's actual avg. flow
f. Total flow for this specific request
g. Total actual and obligated flows to the facility
h. Percent of permitted flow used
5.125
0.00055
5.529
46.1%
II. Complete this section for each pump station you are responsible for along the route of this proposed
wastewater flow.
List pump stations located between the project connection point and the WWTP:
(A) (B) (C) (D)=(B+C) (E)=(A-D)
Design Obligated,
Pump Pump Average Approx. Not Yet Total Current
Station Station Firm Daily Flow** Current Tributary Flow Plus
(Name or Permit Capacity, * (Firm / pf), Avg. Daily Daily Flow, Obligated Available
Number) No. MGD MGD Flow, MGD MGD Flow Capacity***
* The Firm Capacity (design flow) of any pump station is defined as the maximum pumped flow
that can be achieved with the largest pump taken out of service.
** Design Average Daily Flow is the firm capacity of the pump station divided by a peaking factor
(pf) not less than 2.5, per Section 2.02(A)(4)(c) of the Minimum Design Criteria.
*** A Planning Assessment Addendum shall be attached for each pump station located
between the project connection point and the WWTP where the Available Capacity is < O.

III. Certification Statement:
Keri Cantrell 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 certifies that the receiving
collection system or treatment works has adequate capacity to transport and treat the proposed new
wastewater.
