)epnrim:
I Stevie Cox testify 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 tinder 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.

a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for
45.6 % and-0.0039 MGD of the Available Capacity (E) in Pump Station
Steeplegate PS ; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately
.013-22, .050- MGD per year; and that
23,.045-23 for
next 3 years
c. A funded Capital Project that will provide the required planned capacity, namely
Steeplegate PS capacity expansion is in design or under construction with
planned completion in December 2024 ; and/or
d. The following applies:
The overall project based obligations not built result in-0.0039 mgd below the caculated
_available flow for the Steeplegate PS includes flows from homes that will be built out over
the next 3 years that will range from 0.013 mgd in 2022 050 mgd in 2023 and 0.45 mgd in
2024.
During the same period homes will be constricted reducing the obligated flow since only
5000 gal per month adf (or only 170 gpd ) vs the oblicated calculation base on 360 gal per
day per bedroom
The exisitng ADF for each PS is based on 12 months of historical SCADA records
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.

OP
Overview:
The proposed Covington Ridge development is located on a 38.2 acre parcel in the City of Trinity in
Randolph County. The property is located along Unity Street approximately 0.3 miles north of NC 62.
The proposed development will include townhouse units and a commercial outparcel. This submittal is
only for Phase 113. Other permit applications will be submitted in the future for later phases.
Existine Site Description:
The site was primarily grassed with a pocket of wooded area on the eastern side. A ridge runs north to
south roughly through the middle of the parcel. The western portion is flatter and slopes toward Unity
Street at ±2%. The eastern portion is steeper and flows toward a stream near the middle of the eastern
parcel line. Slopes in this portion are more variable and are generally between 4-8%. The project
encompasses the entire 38.2 acre site. The parcel property pin number is 6797239972. The soil on site
consists of Mecklenburg clay loam (MeB2) and Mecklenburg loam (MaC). The site does not lie within a
100-year floodplain or the 500-year floodplain (DFIRM Panel 3710679700J). Currently, the runoff from
the site runs in four main directions; to the west through an NCDOT cross pipe and into a drainage
system that sends flows to a regional storm water pond, to the east into tan existing stream, to the
south into NCDOT line drainage, and to the northeast. The property lies within the Uwharrie River (13-2-
(0.5)) watershed in the Yadkin Pee -Dee River Basin.
Proposed Project Description:
The proposed project consists of a new townhome subdivision, including roads, sidewalks, and
associated utilities. Access to the site will be provided via two (2) entrances on Unity Street and an
additional entrance through a shared access through the parcel in the southeast. A total of 235
townhouse units will be constructed, with 76 units constructed as part of Phase 1B.
Sewer Construction:
The project will use gravity piping and manholes with separate gravity services and cleanouts for each
unit. Proposed sewer improvements for Covington Ridge Phase 1B will tie into proposed sewer
improvements for Covington Ridge Phase 1A, which was previously permitted under Permit Number
WQ0043283. Phase 1B will include approximately 2,195 LF of 8" SDR 26 PVC and 125 LF of 8" DIP. The
proposed sewer system for the Covington Ridge Subdivision will tie into the City of Trinity's existing
sewer system that eventually carries flows to the Hamby Creek WWTP, Permit Number NC0024112.
Stability... Value... Experience... let our experience makeyours better!
