Pump Station (Name or Number): Given that: a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for 54.5 % and -0.071 MGD of the Available Capacity„(E) in Pump Station Steeplegate PS ; and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.04 to 0,05 MGD per year; and that c. A funded Capital Project that will provide the required planned capacity, namely Steeplegate PS capacity expansion is in design or under construction with planned completion in by June 2024 ; and/or d. The following applies: The overall project based obligations not built result in -0.071 mgd belowthe caculated available flow for the Steeplegate PS, includes flows from homes thgt will,be built out over the next 4 to 5 years that will average only 0.04to 0.05 mgd per year over the period During the same period homes will be constructed reducing the obligated flow since only 5000 gal per month adf (or only 168 gpd ) vs the oblicated calculation base on 360 gal per day per bedroom See attched schedule for the expansion of Steepegate PS to a firm design capacity of 1181 gpm or up to 1.7 mgd rate This FTSE prepared by Randy McNeill, PE of DMP 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.
