At the very least, the <br /> separator must be located upstream of the wetpond. <br /> City atandards call for the vault to have an inlet capacity <br /> determined by using the rational formula with a rainfall • <br />', intensity of 0.5 inches per hour. <br /> The vault must be sized to provide a 15 minute detention <br /> time for the design flow. <br /> BypaRs piping is required for the v�ilt per City standards. <br /> The vault inlet capacity should be reached at the point that <br /> the water elevation in the bypass pipe is at its peak for <br /> the 10 year storm. orifice sizing calculations must be <br /> submitted that show that the provided vault inlet meets this <br /> requirement, along with separator design flow and sizing <br /> calculations. <br /> The entire contributing area must be used in calculating the <br /> . size of the oil/water separator vault although only the <br /> paved surface is required to be routed through the <br /> separator. <br />� • <br /> ' The oil/water separator maintenance notes from section <br /> 4.11.1 of the City of Everett Design and Construction <br /> Standards and Specifications must be included on the plans. <br /> Vehicle maintenance <br /> The tenant lease or rental agreement for this project must (" <br /> contain a clause prohibiting vehicle maintenance on the <br /> site.
