摘要： A testable overfill prevention valve (“TOPV”) for a liquid storage container. The TOPV allows an individual to readily verify the operability of the TOPV. Preferably, a test member of directly contacts a portion of a latch to release a flow control member so that the flow control member can move from an open position to a closed position wherein in the closed position liquid is generally prevented from flowing out the TOPV. The test member preferably directly contacts the flow control member to move the control member to an intermediate position between open and closed positions allowing an individual looking down into the TOPV to see that the flow control member has moved sufficiently to confirm operability of the TOPV. Preferably, the test member is spring biased to a non-testing position and the entire test member is disposed in the housing of the TOPV when in a testing position.

摘要： An apparatus for repairing an existing spill containment manhole operably associated with an underground fuel storage tank. The apparatus includes a containment vessel for containing fuel spilled during filling of the underground fuel storage tank. A major portion of the containment vessel is adapted to be inserted into an existing spill containment manhole. Preferably, the containment vessel includes an upper annular flange that extends over and surrounds a portion of an existing cover rim of an existing spill containment manhole thereby isolating an upper portion of the containment vessel from an upper portion on the existing spill containment manhole when the containment vessel is installed. Optionally, a replacement cover is provided to replace an existing cover of the existing spill containment manhole. The replacement cover may include at least one sealing member that engages the inner surface of the at least one wall of the containment vessel when installed.

摘要： A manhole cover assembly removably supported by a manhole skirt or rim wherein when the manhole cover assembly is removed from the manhole skirt or rim an individual can access one or more components (e.g., underground fuel storage tank) through an opening in the manhole skirt or rim. Preferably, the manhole cover assembly is light weight and very strong so that there is little or no deflection of the cover of the manhole cover assembly when subjected to a predetermined load. Preferably, the manhole cover assembly is adapted for use in refueling stations to withstand the load placed thereon when a refueling tanker or other vehicle runs over the manhole cover assembly with little or no deflection of the cover of the manhole cover assembly. Preferably, the assembly forms a liquid tight seal with the manhole skirt to prevent liquid from passing into the storage area below the skirt.
