THE loss of a main shipping channel due to a waste dump and proposed reclamation near Green Island will create a blind corner at the harbour's western approaches likely to increase collisions, mariners have warned. They said the waste dump, the first stage of a massive proposed reclamation which will fill in the Sulphur Channel, would form an accident black spot north of Green Island. Buildings on the new site between Green Island and Western would block the view of fairways for ships leaving and entering the harbour. Instead of the shallow curve through the channel at the moment there would be a blind corner as ships had to slow down to make more than a 90-degree turn to mooring buoys. Vessels approaching and leaving would have little time to spot each other, increasing the risk of collisions. Mariners, through the Hong Kong Pilots' Association and the Seamen's Union, have demanded an urgent meeting with Secretary for Planning, Environment and Lands Bowen Leung Po-wing. Mr Leung claimed the public dump was not part of future reclamation plans although it was gazetted under the title 'Green Island Reclamation (Part) - Public Dump'. Mariners accused him of blinding the public with pro-reclamation 'propaganda' in the form of glossy brochures and exhibitions at the expense of safety. 'The channel is vital for shipping and for the Government to suggest otherwise is an attempt to pull the wool over the public's eyes,' said chairman of the pilot's union Yeung Man-chor. The influential Hong Kong Liner Shipping Association will decide next week whether to formally object to the infill project. 'One of the things we want to do is get a perspective from ship masters on what we should do,' said the association's treasurer, Roberto Giannetta. The seamen's concerns coincide with the formal launch this week of a harbour preservation campaign by senior Town Planning Board member Winston Chu Ka-sun and independent legislator Christine Loh Kung-wai. Ms Loh has sent a copy of a private member's bill banning further reclamation without legislators' sanction to the law draftsman for approval. 'I will touch base in two weeks' time to find out how long it might take the law draftsman to approve the bill,' she said. It can then be tabled in Legco. Ms Loh also plans to challenge the Green Island construction waste dump with a Legco question asking who could object to the proposals after the scheme was gazetted two weeks ago. Only people or organisations who have an interest, right or easement over the foreshore and seabed can object to the project. Mr Chu said this made a mockery of the public consultation process because only those directly affected by the plan could complain.
