October 10, 2023 Fayettevi I le Regional Office — Water Quality Section 225 Green Street Suite 714 Fayetteville, North Carolina 28301-5094 RE: Serenity Phases — 7A & 713 Fast -Track Sewer System Extension Application Wit Project No. 02190647.0 To whom it may concern: DEQIDWR DEC Q 1 'xa'5 WQROS AYF°Trr-►rn i += 4rrinNAl OFFICE On behalf of Harnett Regional Water and Greenfield Communities, please find attached documentation in support of a Fast -Track Application (FTA 10-23) for the above referenced project. As noted in the application, this project will consist of 2,781 LF of gravity sewer that will tie to the previously permitted Serenity Phases 1/2/6 gravity sewer system (WQ0043690) at two existing manholes and eventually end at the Serenity Pump Station. All wastewater generated in the above referenced phases will be treated at the North Harnett Regional Wastewater Treatment Plant (WWTF Permit No. NC-0021636). The proposed project meets all NCDENR-DWR minimum design criteria for sanitary sewer extensions. The design flow rate for these phases is calculated at 25,920 (360 gallons per day per dwelling for a 3-bedroom residence x 72 residences) in accordance with NCAC 2T Rules for wastewater flow rates. The proposed sanitary sewer lines are more than adequate to convey the design flow rates for these Serenity Phases and future expansion. Included with this submittal are one original and one copy of the items listed below: • Application Form (FTA 10-23) • Application Fee — Check in the Amount of $600.00 • Flow Tracking/Acceptance Form (FTSE 10-23) • Site Map (USGS Quad) • Street Level Map (Aerial) Please advise if you require additional information or have any questions concerning our submittal.

Certification Statement: I Steve Ward, Utilities Director certify 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 under 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. off— 'L— �'Z/ Signing Official Signature l Date )-e Title of Signing Official Page 2 of 8 FTSE 10-23 PLANNING ASSESSMENT ADDENDUM (PAA) Submit a planning assessment addendum for each pump station listed in Section H where Available Capacity is < 0. Pump Station (Name or Number): Given that: a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for 42.29 % and 2.436 MGD of the Available Capacity (E) in Pump Station I! C. d SLS-120 : and that The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.3 MGD per year; and that A funded Capital Project that will provide the required planned capacity, namely TBD is in design or under construction with planned completion in TBD ; and/or The following applies: The Town of Anjoer is currently starting process to modify permits to use 75- d per bedroom to reduce its NYT flows, which will correspondingly reduce NYT flow at SLS-120. Additionally, HRW has received earmarked funding for a regional nroiect to divert some flow form SLS-120 to a direct manifold to the SLS-120 forcemain. The project is planned for the 2025-2026 fiscal year. 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.
