This project proposes to serve 2 Three Bedroom Residential units. The requested flow will be for 72o GPD (36o gpd/lot * 2 lots). This flow will be routed to an Existing Manhole located within the Foxwood Ln. public Right of Way, by means of 8" gravity mains with residential services proposed for this site. The Existing MH is located near the southwestern property corner on the north side of Foxwood Ln. within the Public Right of Way. We are proposing to tie to this existing manhole where the receiving downstream sewer size is an 8" line. The flow will ultimately reach the M'Kean Maffitt (SSWWTP) treatment plant WWTF Permit No. NCo023973• Stormwater runoff from this site is discharged to to Mott Creek (Todds Creek), classification C;SW 18-82.

Downstream Facility Name (Sewer): Cape Fear Public Utility Authority Downstream Permit Number: Page 1 of 6 FTSF. 10-1 R Ill. Certification Statement: I Jeff Theberge, CFPUA Eng. Mgr 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. Title of Signing Page 2 of 6 FTSF 1 !1_1 R PLANNING ASSESSMENT ADDENDUM (PAA) Submit a planning assessment addendum for each pump station listed in Section 11 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 46.77 % and 0.791 MGD of the Available Capacity (E) in Pump Station 69 ; and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately TBD MGD per year; and that c. A funded Capital Project that will provide the required planned capacity, namely PS 69 Motts Creek Upgrade is in design or under construction with planned completion in 2023 ; and/or d. The following applies: The PS 69 Motts Creek Upgrade is currently completing design and construction via a Design -Build Contract. This project has been entirely funded as a Capital Improvements Project and once complete will provide adequate capacity for this project. 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.
