Mr. Mellor

factors such as tides, currents, depth of water and prevailing winds. The average length of long sea outfalls is around 2 km. However, local conditions may mean that they can be longer or shorter than this. Relevant studies of the hydrographical conditions near the Royal Portbury dock indicated that a 900 m outfall would be the most appropriate length. Accordingly, a discharge consent for such an outfall was granted by Her Majesty's inspectorate of pollution in July 1987.
