At the retail end, little change in vapour loss is expected, following the introduction of vapour recovery, over what would have been lost to atmosphere before. At the loading gantry, again no more loss of product is found but due to the change to sealed loads, this loss is not 'made up' by added liquid product. An industry initiative should be set up to reduce and quantify these losses and control loading methods and practices. This is not a place for regulation at present. It must be emphasized that good, open measurement leads to fair, honest and just trade.
Poor measurement leads to mistrust, poor contract conditions and increased management costs.
It is in the interests of the industry to provide the best measurement practices and control commensurate with the operations taking place.
