PLANS to extend the KCR to Tsim Sha Tsui will not be approved unless noise is reduced to an acceptable level, a member of the Advisory Council on the Environment insisted yesterday. Plato Yip Kwong-to, who is a member of the council's Environmental Impact Assessment (EIA) subcommittee, said the council would not endorse any project producing noise more than 10 decibels above the limit. 'And we will not agree to any project producing excessive noise for a long period,' he said. The 1.5km extension would cause a maximum construction noise of 97 decibels in the day and 92 at night for up to 20 months, even if mitigation measures were adopted. The noise level would be 22 decibels above the limit - similar to a plane passing over Kowloon City. The new line would run from the present terminus at Kowloon Station, Hunghom, to a new station under Signal Hill in Tsim Sha Tsui. It would be linked to Tsim Sha Tsui MTR station by subways. Most noise would be produced in building a pedestrian subway in Mody Road. A report submitted in September was rejected because it did not meet either the environmental requirements or the technical memorandum of the EIA Ordinance. The Kowloon-Canton Railway Corporation (KCRC) passed new proposals to the Government two weeks ago. A source said the KCRC had kept to the original 'cut and cover' method for building the subway, with the noise level remaining the same. It only reduced the noisy period to 11 months. The corporation offered air conditioners to affected residents, but it is understood residents are unhappy with the proposal as they would have to foot expensive electricity fees. 'The KCRC should explore other less disruptive methods for the subway,' said Mr Yip, otherwise all four green-group representatives in the nine-strong subcommittee would oppose the project.
