Abstract
A system for neutralizing petroleum products leaked into an enclosed portion of a fuel transfer system such as a sump. The system comprises the use of a water insoluble container having a quantity of a petroleum product mitigation agent enclosed therein. A water insoluble barrier for releasing the quantity of mitigation agent upon contact with a petroleum product permits the mitigation agent to neutralize the petroleum product as soon as it is present and in contact with the barrier. The container may be formed from polystyrene and positioned in the sump to permit the release to the petroleum products regardless of the amount of water present in the sump. In one embodiment, the tube is vertically aligned and extends from the bottom to the top of the sump. Alternatively, the container comprises a petroleum product soluble packet and includes flotation aid for maintaining the packet floating on top of any water in the sump. In another embodiment, the container is positioned above the sump and the water insoluble release barrier includes a closure valve for urging release of the petroleum product mitigation agent and a petroleum product soluble rod opposing the closure valve until petroleum product is present in the sump.
