Subject: Fast Track Sewer System Extension Permit Modification Application
Existing Permit No. WQ0041633 - Private
Atrium Union West
1459 Stallings Rd
Stallings, NC 28104
To Whom it May Concern,
Submitted is the fast track sewer system extension application for the modification of Existing Permit
No. WQ0041633 dated May 1, 2020 for the Atrium Union West hospital and associated development
located in Stallings, NC for your review and approval. The modification to the existing permit includes
changes to the permit description, flow allocation, and sanitary sewer lengths.
The existing permit included a total of approximately 1,118 LF of 6" PVC, 481 LF of 8" PVC, 655 LF of
8" DI, and 13 LF of 12" DI private sanitary sewer pipe designed to serve a 200-bed hospital and
central energy plant. The modification requested for this permit includes the addition of 45 LF of 6"
PVC, 182 LF of 6" DI, 7 LF of 8" PVC, and 563 LF of 8" DIP private sanitary sewer pipe.
The included application is for a net total of approximately 1,163 LF of 6" PVC, 182 LF of 6" DIP, 488
LF of 8" PVC, 1,218 LF of 8" DIP, and 13 LF of 12" DIP private sanitary sewer pipe designed to serve
a 200-bed hospital, a 40 practitioner -shift medical office building, and a central energy plant. As in the
existing permit, these buildings will be serviced by a proposed 8" public sanitary sewer which
discharges to an existing 8" public sanitary sewer. Although the nature of all wastewater flows is
classified as domestic/commercial, Union County is requiring a private grinder station as pre-
treatment. These charges area summarized in the chart below. -

III. Certification Statement:
I Crystal O. Panico, PE 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
