October 5, 2022 North Carolina Department of Environmental Quality Division of Water Resources Mooresville Regional Office Water Quality Section 610 E. Center Avenue Mooresville, North Carolina 28115 Re: Fast Track Sewer System Extension Application River District Lift Station #1 - Westrow To whom it may concern, OCT 6 2O22 WQROS MOORESVILLE REGIONAL OFFICE We respectfully submit the attached Fast Track Sewer System Extension Application for River District Lift Station #1 - Westrow. The narrative below has been prepared to provide a summary of the proposed project which supplements the attached application and supporting documentation. Included in this submission: ® NCDEQ Fast Track Sewer Application Form 06-21 (original wet seal / signature) • Cover Letter / Narrative Description (below) • Application Fee of $480 ® 8.5" x 11" USGS Topographic Map • 8.5" x 11" Aerial Location Map River District Overview: The River District consists of over 1400 acres of land located in western Mecklenburg County, between the Charlotte -Douglass Airport and the Catawba River. The rezoning, completed in 2016, approved the entitlements for future phases of development throughout the area. Several infrastructure and roadway projects have already been constructed or are under construction to provide vehicular and pedestrian access as well as water and sewer to a previously unserviced area. The River District will additionally annex developed parcels to the City of Charlotte, coordinating roadway maintenance between NCDOT and CDOT where appropriate. Westrow Lift Station: This application is for the first pump station associated with the River District, referred to as River District Lift Station #1 — Westrow (or the Westrow Lift Station), which is proposed to be installed in coordination with the LANDDESIGN.COM approved Westrow Phase 1 Infrastructure Land Development Plans and is dependent on several infrastructure projects as described below. The Westrow Lift Station is the first pump station and force main system proposed in the River District and has been designed to serve the full build -out condition of the contributing service area. A detailed Preliminary Engineering Report was approved by Charlotte Water in 2019 which detailed the service area and anticipated service demand based on the entitlements in the rezoning as well as existing and future development in the area. Sheet 17 of the Westrow Pump Station Plans references and expands on the analysis and basis of design. The proposed station will be a duplex pump system, sized for an operating point of 1600 gpm at 177 ft in TDH. Sheet 16 provides the pump curves for the selected pumps as well as other design information. These plans have been reviewed and approved by Charlotte Water. The discharge from the pump station is routed via a 12" forcemain to tie into the proposed gravity receiving sewer as shown in the Water and Sewer Plans for Westrow, also reviewed and approved by Charlotte Water. Water service is provided to the Westrow Development by the 24" Dixie River Watermain and the downstream trunk sewer is the 24" Beaverdam Trunk Sewer, which ultimately routes the discharge to McAlpine Wastewater Treatment Plan. This application reflects zero flow to the pump station as a part of the Westrow Phase 1 Infrastructure Project under which the station will be installed. The first phases on contributory development will being in 2023 and will be submitted under separate applications Please do not hesitate to reach out with any questions or concerns on the contents of the application. I can be reached at MSchultz@landdesign.com or 704-333-0325 x1011 anytime.

We find the plan to be acceptable and hereby issue this Letter of Approval. This plan approval shall expire three (3) years following the date of approval, if no preconstruction meeting and land -disturbing activity has been undertaken, as is required by Title 15A NCAC 4B .0129 and Section 17-35(b) of the City of Charlotte Code of Ordinances. Acceptance and approval of this plan is also conditioned upon your compliance with Federal, State, and local water quality laws, regulations, and rules. As of April 1, 2019, all new construction activities are required to complete and submit an electronic Notice of Intent (NOI) form requesting a Certificate of Coverage (COC) under NCG01000 Construction Stormwater General Permit. This form MUST be submitted prior to the commencement of any land disturbing activity on the above -named project. The NOI form may be accessed at deq.nc.gov/NCG01. Please direct questions about the NOI form to Annette Lucas at annette.lucas(cncdenr.gov or Paul Clark at uaul.clarkncdenr. ov. After you submit a complete and correct NOI Form, a COC will be emailed to you within three business days. Initially, DEMLR will not charge a fee for coverage under the NCGO 1permit. However, on or after May 1, 2019, a $100 fee will be charged annually. This fee is to be sent to the DEMLR Stormwater Central Office staff in Raleigh. Westrow Phase 1 Infrastructure December 1, 2021 Page 2 of 2 Upon receiving this approval, it is the responsibility of the Financially Responsible Party, their agent, or the owner to request a pre -construction meeting by completing the Pre -Construction Meeting Request Form found at https://charlottenc.seamlessdocs.com/f/cORAt. Please provide at least 48 hours advance notice for the pre -construction meeting so that City Staff may coordinate and schedule the appropriate personnel. No land disturbance of any kind, including any demolition, is allowed prior to the pre -construction meeting Title 15A NCAC 4B .0118(a) and the NCGO1 permit require that the following documentation be kept on file at the job site: 1. The approved E&SC plan as well as any approved deviation 2. The NCGO1 permit and the COC, once it is received 3. Records of inspections made during the previous 30 days. Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of periodic inspection to insure compliance with the approved plan. The City of Charlotte's Sedimentation Pollution Control Program is performance -oriented, requiring protection of existing natural resources and adjoining properties. If, following the commencement of this project, it is determined that the erosion and sedimentation control plan is inadequate to meet the requirements of the City of Charlotte Code of Ordinances and the Sedimentation Pollution Control Act of 1973 (G.S. 113A-51 through 66), this office may require revisions to the plan and implementation of the revisions to insure compliance with the Act and Local Code. Acceptance and approval of this plan is conditioned upon your compliance with Federal, State, and County water quality laws, regulations, and rules. This approval does not supersede any other permit or approval. Approval of this plan is based in part on the accuracy of the information provided in the Financial Responsibility Foiui, which you provided. You are requested to file an amended form if there is any change in the information included on the form. Your cooperation is appreciated.
