PROJECT NARRATIVE- MODIFICATION
Raleigh -Wilmington Investors, LLC previously permitted the sanitary sewer for a single-family
neighborhood at 1319 Lt. Congleton Road (WQ0039770, 02/13/18). At final build -out the
neighborhood will consist of 170 single family lots and amenities that is served with sanitary sewer
outfalls between two (2) existing Cape Fear Public Utility Authority manholes [Sentry Oaks Pump
Station (SSA-131) to the north and Intracoastal Watch PS (SSA-115) to the south].
The new owner, Clayton Properties Group, Inc., has since revised a minor portion of the
development that has resulted in the need to modify the sanitary sewer network and associated
permitting. The revised total flow numbers for each pump station are as follows. Sentry Oaks PS —
113 lots and amenity (41,634 gpd) and Intracoastal PS — 57 lots (20,520 gpd). The previous
approved permit included 53 lots (19,080 gpd) to the Intracoastal PS. As a result, this modification
only requires permitting an additional 4 lots to satisfy the site changes (1,440 gpd). Also, please note
that the previous approved permit included the flow of 56 lots (20,160 gpd) to Sentry Oaks PS
which will remain and not be affected by this modification. The total flow for the site, all of which
is going to Mckean-Maffit Wastewater Treatment Plant, has not changed.
The previously permitted gravity sewer line length was 8,060 If. The site changes have resulted in
needing 8,450 if of total gravity sewer; therefore, please find that this modification includes 3901f to
make up the difference.

III. Certification Statement:
I Jeff Theberge, CFPUA Eng. Mgr 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
47.7 % and 0.822 MGD of the Available Capacity (E) in Pump Station
69 ; 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
Mons Creek is in design or under construction with
planned completion in TBD 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.
