Mgr certify to the best of my knowledge that the addition of the volume ofwastewater 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. Official Page 2 of 6 FTSE 10-18 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 29.34 % and 1.734 MGD of the Available Capacity (E) in Pump Station PS 89 ; and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately N/A MGD per year; and that c. A funded Capital Project that will provide the required planned capacity, namely Sidbury Road FM is in design or under construction with planned completion in 2022 ; and/or d. The following applies: The Sidbury Road force main is under construction and is permitted such that flow can either flow through Pump Station 89 or down the Blue Clay Road force main CFPUA has a funder Developer Capital project to complete the tie in and send Sidbury Road FM flow through the Blue Clay Road FM as planned This will reduce the permitted flow through PS 89 by 92,880 GPD leaving 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.
