Imperial Oil's Hay River Distribution Terminal is required to conduct hydrostatic testing on one of its above ground tanks in order to maintain compliance with above ground tank standards (API 653) which have been adopted by the National Fire Code. This will require up to 3000m3 of water to be drawn from Hay River. Water will be withdrawn in quantities of 300 m3 daily until there is a sufficient volume in the tank to properly conduct the hydro-test. The discharge pipe will be suspended to a depth of 2 feet from the dock in order to prevent erosion of the river bank or river bed and a suitably sized fish screen for this flow rate will be used at the intake of the hose to minimize impact to aquatic life.  The tank to be hydrostatically tested is clean of hydrocarbons and has been gas freed. Intake from the river will be filtered and then sampled for pH level, metals, BTEX, phenols, total hydrocarbons , and oil & grease per CCME Release Requirements before entering the tank. Once the tank has the required volume of water, it will be held for 48 hours. After this hold period, the water will be sampled for the same parameters from several locations within the tank. The water, when it is deemed to be at comparable testing levels to the intake water, will be discharged back into Hay River at a rate not to exceed 300m3/day.
