restricted hours will be retained, and in addition,

percussive piling will in future also require a permit

during daytime hours. This will make it possible to limit

noisy percussive piling to certain hours of the day in

In connection with the permit system, the Bill

c. introduces the concept of Technical Memoranda which will be

issued by the Secretary for Health and Welfare on the advice

of the Director of Environmental Protection and which will

contain detailed technical principles for the prediction,

assessment and measurement of noise. These principles will

be applied in order to determine whether or not a permit

should be issued in any particular case and what conditions

should be included.

The Bill also introduces controls on noise from

commercial and industrial premises. Clause 11 provides that Noise Abatement Notices may be served if the noise

emitted is causing annoyance to any person, or if it does

not comply with the technical criteria set out in the

le relevant Technical Memorandum. These notices will require

owners or occupiers to ensure that their noise emissions

comply with the requirements of the notice by a specified

and

date; non-compliance will be an offence.
