* 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

III. Certification Statement:
I Warren Wood 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.

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
49.88 % and 0.862 MGD of the Available Capacity (E) in Pump Station
Sandy Ford ; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately
0.021 MGD per year; and that
c. A funded Capital Project that will provide the required planned capacity, namely
Henry River Pump Station Upgrades is in design or under construction with
planned completion in 2024 ; and/or
d. The following applies:
An upgrade to this pump station is currently in design with construction to follow
immediately. This will increase the firm capacity to 11.52 MGD to allow for economic
development projects. This upgrade will be constructed prior to the existing capacity being
exceeded based on the current rate of activation.
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.
