The scope of this phase of the project will include the construction of 64 single-family homes and 49 townhomes on 29.49 acres. The project is anticipated to generate 320 gallons per day (gpd) of wastewater flows per single-family unit and 240 gpd per townhome unit for a total development flow rate of 32,240 gpd. The proposed gravity sanitary sewer system will consist of approximately 3,617 LF of 8" PVC and 755 LF of 8" DIP. The new gravity sanitary sewer system will be owned, operated, and maintained by the City of Graham. !G (�(� U.S. DEPARTMENT OF THE INTERIOR �M, BURLINGTON QUADRANGLE iUSGS U.S. GEOLOGICAL SURVEY ptE NORTH CAROLINA- AL —ICE COUNT t Moo ].5-MINUTE SERIES nobxW eY uH Untie! w n Igktl s,mar ...

Drawer 357 Graham, NC 27253 Subject: Residential Flow Reduction Approval Graham Collection System (WQCS00065) City of Graham Alamance County Dear Mr. Holland: On January 10, 2023, the Division of Water Resources (Division) received a request for an adjusted daily sewage flow rate (flow reduction) that would apply to all permitted but not yet tributary residential connections and all future residential connections within the City of Graham service area. In accordance with 15A NCAC 02T .0114(f)(2), the Division has evaluated the request, and based on the data submitted, the Division hereby approves for use by the City of Graham an adjusted daily sewage design flow rate with the following conditions: • The flow reduction is applicable to residential single-family and multi -family dwellings only. • The minimum flow for 1- and 2- bedroom dwellings shall be 160 gallons per day. • Each additional bedroom above two bedrooms shall increase the volume by 80 gallons per day per bedroom. • This flow reduction shall not apply to sewer extension applications and/or permits for any other public or private organizations whose wastewater flows are or might become tributary to the City of Graham collection system (WQCS00065). Future sewer extension applications should be made using the flow reduction amount stated above. All other aspects of the permitting process remain unchanged, and all applications must be in compliance with the statutes, rules, regulations and )minimum design criteria as certified by the owner and engineer.

In accordance with 15A NCAC 02T .0114(f), the Division periodically requires reassessment of wastewater flow data associated with the collection system or the receiving wastewater treatment plant as applicable to confirm the suitability of the approved flow reduction value. The City of Graham shall submit documented representative data in accordance with 15A NCAC 02T 0114( (1)(A-H) prior to January 31 2031 Failure to submit the required data by this date will result in this flow reduction approval letter becoming null and void. Upon review of the data, the Division shall either reapprove modify or not grant reapproval for the previously approved flow reduction value. The granting of this flow reduction does not prohibit the Division from reopening, revoking, reissuing and/or modifying the flow reduction as allowed by the laws, rules, and regulations contained in 15A NCAC 02T, NCGS 143-215.1, or as needed to address changes in State and/or Federal regulations with respect to wastewater collection systems, protection of surface waters, and/or wastewater treatment.
