Our Responsibilities

We aim to prevent, minimise and resolve environmental noise problems through intervention in the planning process, implementation of noise abatement measures and enforcement of the Noise Control Ordinance.

Noise Exposure

Noise has an enormous social impact in Hong Kong. More than one million people are affected by excessive traffic noise alone. Thousands of others are affected by construction, rail, commercial and other noise sources. The EPD is working hard to minimise the impacts on these receivers.

Traffic Noise

Traffic noise is addressed in two ways: by preventing noise from new roads through input in the planning process, and by reducing noise from existing roads.

New roads

Since 1986, 45 kilometres of noise barriers and enclosures have been installed on new roads, protecting
173 000 people. Yearly cumulative length of screening structure and number of people benefited are shown in Figure 1.

Since 1995, 7 400 flats have been insulated from noise through acoustic insulation and air-conditioning as seen in Figure 2.
Low-noise surfaces are the standard for new roads with speeds of 70 kilometres per hour or higher.

Figure 2 - Accumulated Number of Dwellings Insulated in 2004 (See Data)

Existing roads
Construction of about three kilometres of barriers along Fanling Highway was commenced in 2004, to ease traffic noise for about 2 000 dwellings in Fanling and Sheung Shui. This is part of a retrofitting programme to erect barriers and enclosures on over 30 roads (see programme details at Table 1). The Fanling project will cost $139 million, be completed by the end of 2005 and reduce traffic noise by up to 17 dB(A).
Seventy-two road sections are to be re-surfaced with a low-noise surface. Work on the first batch of 24 road sections began in 2002. In 2004, work began on the second batch of 22 road sections.

Construction Noise

An amendment to the Noise Control Ordinance came into effect on 8 October 2004, making corporate directors liable for repeated noise offences by their companies. This followed publication of two Codes of Practice describing good management practices for avoiding noise violations. Directors receive a warning letter after a first offence. If another offence occurs within two years, they can be prosecuted. Defendants can use a due diligence defence if they have put an environmental management system in place and are operating it effectively. Information seminars on the matter were held in October and attended by more than 500 people.

Raising Awareness

3-D tool: The EPD aims to enhance people's understanding of noise and the impacts of proposed new projects and mitigation measures. A significant achievement in 2004 was the introduction of a three-dimensional visualisation tool. This easy-to-understand visual guide lets people see the noise impacts of proposed projects from different angles, and enables more informed public input during consultation. Two hypothetical examples were posted on the EPD website to demonstrate how the tool works.

Education package: Greater understanding of environmental noise is also being promoted through an interactive education package. A website, with sections targeted at the general public and at young people, was launched in December 2003. The second part of the package, a CD-ROM, was distributed to schools, libraries and other users in 2004.

Noise study: A study on noise in Hong Kong, initiated in late 2003, proceeded in 2004 and will provide detailed information on the many sources of noise and the effects on receivers. It will be completed in 2005 and the results will be used to help formulate new policies and measures to control noise.

Staff exchange: A six-month staff exchange with the Highways Department was completed in 2004, enabling a better understanding of the priorities and constraints each department faces.

Active Participation in the Planning Process

Since 1986, over 140 000 flats have been protected from excess noise through EPD intervention in the planning process.

The EPD provides professional advice to minimise noise through land use and planning activities. In 2004 we provided input on 1 418 advice/cases. See breakdown at Figure 3.

Input is also provided on strategic-level noise improvement measures, as identified in the Third Comprehensive Transport Study published in 1999, and progress can be viewed at Table 2.

Table 2 - Report and Progress on Various Improvement Measures Identified in CTS-3

Type of Measures Recommended Strategic Level Noise Improvement Measures Current Progress
Policy More extensive use of rail service About 13 km of railways were put into operation in 2004. 11 km of railways are being constructed and others are being planned.
Putting new roads underground as far as practicable The Environmental Impact Assessment Ordinance requires exhausting direct mitigation measures which would include underground road alignment.
Pedestrianisation Several schemes implemented and additional schemes are being studied.
Engineering More stringent vehicle noise emission standards Regulation was amended in 2002 to follow latest European Union and Japanese requirements.
Trolley buses In light of the feasibility study findings, the merits of implementing a pilot trolley bus scheme in a southeast Kowloon development vis-a-vis other environmentally friendly transport modes will be examined.
Measures at Source More extensive use of low noise road surfacing 72 local road sections will be resurfaced under the new policy endorsed in November 2000.
Retrofitting existing roads with barriers or enclosures Construction of Fanling Highway retrofitting projects commenced in August 2004. Design work for other retrofitted barriers in the first batch of projects is in progress.
Management Possibilities Traffic management on noise ground Trial of traffic management scheme at Texaco Road Flyover was carried out in mid-2004.
