NC Department of Environmental Quality Received SEP 2 8 2021 Winston-Salem Regional Office 7A Wendy Court - Greensboro, NC 27409 - (336) 294-9394 Green Mountain Engineering, PLLC Civil Engineering Consultants Project Narrative For Rogers Spring — Phase 2 Located in Graham, NC September 27, 2020 To Whom It May Concern: Rogers Spring is a proposed 166 unit +/- single family subdivision. The Project is being phased into multiple parts. The sewer outfall serving Phase 2 of this subdivision will tie into an existing 8" sewer main constructed during Phase 1B. Approximately 3,122 linear feet of new 8 inch sewer mains with 59 new services will connect to the existing 8" main for Phase 1B. For Phase 2, a total of 59 new residences are planned for this subdivision. The design and plan review was done in accordance with NCDEQ's Gravity Sewer Minimum Design Criteria and the City of Graham's standards and specifications. Work on the sewer installation is planned to begin once the permit has been obtained. Please contact me if you require additional information. You can reach me via email vine@greenmountainengineers.com or by telephone (336)-294-9394 at your convenience. Respectfully submitted, Vincent C. Townsend, P.E.
