4h. Explain the purpose of the proposed project: *
The purpose of this project is to construct the Stowe RWRRF & Associated Infrastructure Projects to meet the increasing population growth demands for the treatment of wastewater for
Mt. Holly, Belmont, and the Long Creek Basin in Mecklenburg County.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
This Project proposes a regional VVWTP (Stowe RWRRF) in Mecklenburg County, located approximately adjacent to the existing Long Creek Pumping Station (PS). This regional facility
would initially have a treatment capacity of 15 million gallons per day (mgd) and have the ability to take wastewater flows from two existing facilities: the Mt. Holly Wastewater Reclamation
Facility (WRF) and Clariant, an adjacent industrial facility; and wastewater flows from the Long Creek basin. Through a future expansion, the Stowe RWRRF would treat 25 mgd and be
able to handle wastewater flows from the Belmont W WTP via the Paw Creek PS.
Once connected to the Stowe RWRRF through the proposed project, the effluent outfalls at the Mt. Holly WRF and the Belmont WWTP would be eliminated. Prior to the Stowe RWRRF
construction, the Charlotte Water wastewater treatment system would treat flows from the Mt. Holly WRF and the Belmont W WTP. It would also eliminate the need for expansions and
rehabilitations of the outdated Mt. Holly and Belmont facilities while still serving existing and anticipated treatment capacity needs for the region.
The US Army Corps of Engineers (USACE) requested that the Applicant submit a project -wide Clean Water Act (CWA) Section 404 application to include future construction projects
(elements) that would propose impacts to Waters of the U.S. (WoUS). This permit will take a phased approach, providing design and details on the most imminent elements of the Project,
while providing only high-level planning details for future elements yet to be designed
5. Jurisdictional Determinations

6. Future Project Plans
6a. Is this a phased project?*
O Yes O No
6b. If yes, explain.
In Phases 1 a through 1 c, the existing Long Creek PS would be replaced with a new pump station and headworks facility on the same site in order handle wastewater flows from the Mt.
Holly WRF. These flows would be pumped beneath the Catawba River to the replaced Long Creek PS by horizontal directional drilling (HDD) methods, would continue from the current
Long Creek PS site to the Paw Creek PS, and then on to larger Charlotte Water treatment facilities via the existing system. A new pumping station would be constructed at the Mt. Holly
WRF site so that the WRF could be decommissioned. Additionally, access roads and power transmission would be constructed to the regional facility location.
This permit application seeks authorization for Phase 1. Phases 2-3 are still in the planning stages and proposed impacts to WoUS for these future phases will be considered cumulatively.
Are any other NWP(s), regional general permit(s), or individual permits(s) used, or intended to be used, to authorize any part of the proposed project or related activity?

Forcemains will be horizontally drilled beneath the Catawba river. This would not constitute any impact to surface waters. Forcemain crossings of Long
Creek will also be horizontally drilled and will not cause impacts to surface waters. Effluent outfall will occur underneath the ordinary highwater mark and
will be reinforced with riprap. This will constitute approximately 27 feet of impact located only on the bank of the river.

With proposed impacts 10 and 11, approximately 1,288 square feet of Zone 1 and 927 square feet of Zone 2 of the Catawba River Buffer will be cleared.
half this amount will be used to maintain a new easement for the utility lines associated with the outfall from the wastewater treatment plant. Under use
'kk' Zone 2 impacts are deemed allowable, and Zone 1 impacts less than 2,500 square feet are allowable with written authorization. The second half
would be under the use 'rr' as this will provide access to the surface water and to a dock that will be for upkeep of the outfall, the width of which will be
less than 15 feet.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
To avoid and minimize impacts to waters of the U.S., the project area was delineated for jurisdictional streams and wetlands. Because the Catawba
River is a Traditionally Navigable Waterway (TNW), Section 10 authorization is required for any impacts beneath, through, on, or over the river. For
those impacts to the Catawba River that propose forcemain installation by HDD, no changes or structures are proposed for the water surface, water
column, or riverbed so no hazards to navigation are anticipated. For those impacts to the Catawba River proposed on the surface of the river, design has
not yet commenced. Any element of this project that would require future impacts in Phase 2-3, refined designed and calculated impacts would be
submitted to the USAGE prior to construction.
The EIS and approved ROD already considered alternatives for the overall Stowe RWRRF project, location, and HDD methods verses other wastewater
treatment options. Impacts associated with the Stowe HW&IPS (Impact 1) cannot be avoided due to the existing location of the Long Creek PS. Impacts
associated with the Stowe RWRRF are isolated and not regulated by the USACE (Impact 7) or are in a future phase (dock and effluent outfall) (Impact
8). As such, the alternatives considered here are associated with the road access alignments (Impacts 3, 4 and 6). Impacts 2 and 9, and are Section 10
impacts to the Catawba River, but do not propose surface water impacts. The No -Build Alternative would not involve the construction of a new regional
treatment facility; however, it would include upgrading the existing Mt. Holly WRF and Belmont WWTP. It would also require substantial wastewater
collection system upgrades to the Charlotte Water system. In the absence of the project, capacity for wastewater treatment would be inadequate in
providing these services for the existing and anticipated population. The No -Build Alternative would not meet the purpose and need of the project.

lb. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Erosion and sedimentation control measures will be properly installed and inspected in accordance with a NPDES Erosion and Sedimentation Control
(ESC) permit. Erosion and sedimentation BMPs will be installed prior to construction. Impacts will be minimized by strict enforcement of Best
Management Practices for the protection of surface waters, including restrictions against the staging of equipment in or adjacent to waters of the US.
Piling drive techniques will be utilized for bridge construction to minimize the impact footprint of the bridge bents. This project will follow all conditions of
NWP 12 and NWP 14, including their respective Water Quality General Certifications (WGC) 4133 and 4135. Equipment to be used includes excavators,
dump trucks, earthmovers, cranes, and HDD equipment.

(acres) (acres)
4h. Comments
Approximately 33.68 acres of wetlands with 14,856 linear feet of stream were identified on site. According to site design, 0.229 acres of jurisdictional
wetlands will be impacted. These impacts are proposed to be mitigated as a 2:1 ratio which amounts to mitigating the equivalent of 0.458 acres. 0.4
acres have already been purchased for this project under the original permitting process. An additional 0.058 acres have been confirmed to be available
from the City of Charlotte Umbrella Stream and Wetland Mitigation Bank. No mitigation is required for impacts to the non -Section 404, isolated wetland
impacts (0.22 acre).

OYes 0No
Comments:
The project is subject to the City of Charlotte's Post Construction Stormwater Ordinance (PCSO) and Zoning Ordinance Section 12.601. Phase 1 of the project is below 12% BUA. The
project qualifies as a low density development under the PSCO and therefore must treat runoff through vegetated conveyances to the maximum extent practicable and not required to
perform peak discharge control. The project is subject to 100-foot water supply watershed buffers and 100 foot +50% flood fringe post construction buffers. As subsequent phases are
designed, Stormwater Management Plans will be supplied to the City of Charlotte for review.
