Downstream Facility Name(Sewer): North Harnett Regional WWTP Downstream Permit Number: NC0021636 III. Certification Statement: ' 5-Fe ye_ a.rcLf 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 Clow 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 indicates acceptance of this w ewater flow. Signing Official Signature Date Page 2 of 3 FTSE 06-13 0 PLANNING ASSESSMENT ADDENDUM(PAA) Submit a planning assessment addendum for each pump station listed in Section II where Available Capacity is<0. Pump Station(Name or Number): SLS-120 Given that: • The proportion and amount of Obligated,Not Yet Tributary Daily Flow(C)accounts for 57.55 %and 3.315 MGD of the Available Capacity (E)in Pump Station SLS-120 _... _ ;and that • The rate of activation of this obligated,not.et tributary capacity is currently approximately 0.3 MGD per)ear;and that • A funded Capital Project that will provide the required planned capacity,namely TBD is in design or under construction with Manned completion in _1 TBD _ I;and/or • The following applies: HRW is currently reconciling actual and not-yet-tributary flows to accurately assess available capacity. The reconciliation is expected to be completed in June 2023. Given the size of the pump station,the percentage of not-yet-tributary,and the rate of activation,this will be the first step to determine if potential CIP project is needed and timeline for any capacity increase. 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. i) /./ 1,1— �4 Signing Official Signer ure Date Page 3 of 3 FTSE 06-13 • State of North Carolina • DWR Department of Environmental Quality Division of Water Resources 15A NCAC 02T.0300—SEWER SYSTEM EXTENSION APPLICATION Division of Water Resources SSEA 04-16&SUPPORTING DOCUMENTATION Application Number: (to be completed by DWR) I.
