This is a notice of capacity for the flow acceptance request received by the Water and Sewer Authority of
Cabarrus County (WSACC) from the Town of Harrisburg on August 12, 2020, WSACC has or will have
capacity at the Rocky River Regional Wastewater Treatment Plant and appropriate sewer interceptors to transport
and treat the domestic wastewater from the proposed project entitled Commons at Farmington, located off
Farmington Ridge Parkway. The referenced project will serve a residential development with 36 five -bedroom
homes and 112 three -bedroom homes, with a projected wastewater flow of 61,920 gallons per day (gpd). The
wastewater generated by this project will be conveyed through a proposed gravity system and then enter
WSACC's system at the existing 18-inch Fuda Creek Interceptor. WSACC acknowledges it has or will have
capacity for wastewater from the proposed development based on information provided by The John R,
McAdams Company, Inc. using North Carolina Department of Environrnental Quality (NCDEQ) wastewater flow
guidelines.
if construction of this project does not commence within two (2) years of the date of this notice, the notice is
rescinded and a second request and notice will be required before flow capacity is accepted. Please notify
WSACC, in writing, when construction of this project is initiated, This sewer capacity allocation may also be
cancelled pursuant to the conditions set forth in the WSACC Sewer Allocation and. Commitment Policy.
Please note that the final commitment to service to provide wastewater treatment services shall occur upon
application for a building permit for the protect and when system development fees are paid pursuant to
tV C,G.S. §lb2A, Article 8.

PLANNING AST ADDENDUM (PAA)
Submit a planning assessment addendum for each pump statirn listed in Section II where Available Capacity is < 0.
Pump Station (Name or Number): Lower Rocky River Pump Station
Given that:
a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for 23.3% and 3,751 MOD of
the committed flow in the Lower Rocky River Pump Station; and that
b. The rate of activation of this obligated, not yet tributary capacity is currentlyapproxiinately
1,806 MGD per year (please see second paragraph below); and that
c. A funded Capital Project that will provide the required planned capacity, namely Lower Rocky River Pump Station
Expansion is in design or under construction with planned completion in December 2021; and/or
d. The following applies:
Per guidance from Town of Harrisburg and the developer, it is expected that the Commons at Farmington project
will be constructed and certified by October 2025, and a phased build -out is proposed for this project.
I
WSACC has been ►working with Brown and Caldwell since February 2020 to study an expansion of the Rocky River
Regional W'WTP, which includes study of expanslo9 for the Lower Rocky River Pump Station. The Lower Rocky
River Pump Station currently includes four pumps, with space available for two additional pumps and associated
piping. WSACC plans to initiate formal design in S ptember 2020 for implementation of additional pumping
capacity at the Lower Rocky River Pump Station. iven that space is already available for two additional pumps,
and that some associated piping is already in place, SACC currently anticipates that design and construction for
implementing additional capacity at the Lower Rocky River Pump Station can be completed by the end of 2021.
Based on recent analyses by Brown and Caldwell, WSACC expect that the firm capacity of the upgraded Lower
Rocky River Pump Station will be around 53.3 MGD, meaning that WSACC expects the "design average daily flow"
of the upgraded Lower Rocky River Pump Station wail be around 21.3 MGD.
Based on flow trends so far in 2020, WSACC expects the overall 2020 annual average rate of activatiou for obligated,
not yet tributary capacity to be lower than the tsoq MGD per year indicated above (from calendar year 2019). The
increase in flow at the Lower Rocky River Pump Station in calendar year 2019 was heavily influenced by significant
and persistent rainfall events. The year-to-date average flow for 2020 is approximately 11.2 MGD, much lower than
the 12.346 MGD annual average from 2019, which was heavily influenced by the referenced rainfall events. With the
combination of lower actual flows so far In 2020 and an expected lower rate of activation for obligated, not yet
tributary flows relative to the values experienced in 019, WSACC does not currently anticipate issues with design
capacity at the Lower Rocky River Pump Station p for to completion of the planned capacity upgrades at the Lower
Rocky River Pump Station.
Finally, WSACC is also working with a consulting engineer on design and related work for the Back Creek
Interceptor Improvements protect. Completion of construction for the Back Creek Interceptor Improvements
protect is expected in early 2022 (after the expansion of the Lower Rocky River Pump Station is complete), and will
result in an additional 1.1 MGD of wastewater flow from Charlotte Water conveyed to the WSACC system, which
will lead to additional flow at the Lower Rocky River Pump Station. NC DEQ has issued a permit for the Back
Creek Interceptor Improvements Project, and tutu ed on that permit a stipulation that, prior to any flow being
tributary from the Back Creek Interceptor Improv4ments Project, the planned capacity upgrades at the Lower
Rocky River Pump Station must be completed and ertified.
Therefore:
Given reasonably expected conditions and planning inflarrnation, there is sufficient justification to allow this flow
to be permitted, without a significant likelihood of over-allocatrng capacity in the system infrastructure..
I understand that this does not relieve the collection sysern owner from complying with G.S. 143- 215.67(a) which
