Disney has won official backing for its fireworks after deeming its own tests met enviromental standards, despite gaps in the information it provided to an environmental watchdog.
It said some data on air quality and noise levels were lost during the trials.
The Advisory Council on the Environment said yesterday a fireworks trial on May 6 and 7 met noise and air quality requirements in general but it wanted Disney to provide more information.
A report submitted by Disney said the noise level recorded in Discovery Bay and Peng Chau was slightly lower than the legal limit of 55 decibels, while air pollutants also met standards.
Despite the missing data, environmental officials said Disney could carry out firework displays because the company's environmental impact assessment report submitted in 2000 had already been approved.
But council member Mei Ng Fong Siu-mei said the latest report was non-conclusive on the real impact, given the data loss and short duration of the fireworks' trial. She urged Disney to abandon fireworks, warning that fireworks, on top of cheering crowds, could push noise levels beyond legal limits.
