Abstract
A storm drain filter system apparatus includes a skimmer tray having a sediment collection closed bottom and having an inlet side and an outlet side and a hydrocarbon absorbing boom. A plurality of boom support brackets each has a boom holding portion for holding the boom therein and a spacing arm extending from the boom holding portion and attached to one side of the skimmer tray to space the boom in the boom holding portion between the inlet side and the outlet side of the skimmer tray. The skimmer tray extends all or partly around the storm drain opening forming an open center area to allow overflow liquid to flow over the outlet side through the middle area. Sediment is collected in the bottom of the skimmer tray and the boom is supported spaced between the inlet and outlet side of the skimmer tray to capture hydrocarbons and liquid entering the skimmer tray. The liquid enters the skimmer tray on one side of the boom and out the other side of the boom. The boom is supported at the liquid level of the skimmer tray so that the liquid is forced therearound allowing the boom to collect the hydrocarbons and the sediment to settle in the bottom.
