Environmental Impact Assessment Ordinance (Cap. 499)
Section 5 (7)
Environmental Impact Assessment Study Brief No. ESB-085/2001
Project Title : Sheung Shui to Lok Ma Chau Spur Line
Name of Applicant : Kowloon Canton Railway Corporation (KCRC)
1.1 The proposed Sheung Shui to Lok Ma Chau Spurline (the project) is to extend the Kowloon Canton Railway East Rail network from Shueng Shui to a new railway station and associated cross-boundary facilities at Lok Ma Chau. The trains to be operated on the project are electrically powered. The project is a Designated Project under Schedule 2 of the Environmental Impact Assessment Ordinance (EIAO), and requires an environmental permit under the EIAO for its construction and operation.
1.2 On 10 February 1999, the Director of Environmental Protection (the Director) issued to the Applicant an EIA study brief (ESB-026/1999) under the EIAO to carry out an EIA study on the project.
1.3 On 27 April 2000, the Applicant submitted an EIA report on the project to the Director for approval of the report and granting of an environmental permit for the construction and operation of the project. A revised EIA report was exhibited for public inspection in June 2000. On 16 October 2000, the Director decided not to approve the EIA report and not to issue an Environment Permit for the project. The reasons for rejection have been deposited in the EIAO Register.
1.4 On 10 November 2000, the Applicant lodged an appeal to the Appeal Board against the Director's decision (1) not to approve the EIA report; and (2) not to issue an Environment Permit for the project. The Appeal Board handed down its judgement on 30 July 2001 and dismissed the two appeals by KCRC.
1.5 Subsequent to the Appeal Board's determination, an application (No. ESB-085/2001) for an EIA study brief under section 5(1) of the EIAO was submitted by the Applicant on 19 September 2001 with a project profile (No. PP-144/2001) containing a revised scheme and construction method on the project. The key change to the project is the railway alignment which will now travel through Long Valley, Kwu Tung and Chau Tau in an underground tunnel instead of on viaducts before it climbs to viaducts alongside and terminates at Lok Ma Chau.
1.6 Pursuant to section 5(7)(a) of the EIAO, the Director issues this EIA study brief to the Applicant to carry out an EIA study on the revised scheme of the project.
1.7 In setting out the scope of the issues to be addressed in this EIA study, the Director has given due regard to his decisions on rejecting the previous EIA report of the project, the Appeal Board's determination, relevant materials presented in evidence to the Appeal Board, the comments from the Advisory Council on the Environment and the comments received from the public during the public exhibition of the current project profile. The purpose of this study brief is to scope the key issues of this EIA study and to specify the environmental issues that are required to be reviewed, updated and assessed in the EIA report.
1.8 The purpose of this EIA report is to provide information on the nature and extent of environmental impacts arising from the construction and operation of the project and related activities taking place concurrently. This information will contribute to decisions by the Director on:
(i) the overall acceptability of any adverse environmental consequences that are likely to arise as a result of the proposed project;
(ii) the conditions and requirements for the detailed design, construction and operation of the proposed project to mitigate against adverse environmental consequences wherever practicable; and
(iii) the acceptability of residual impacts after the proposed mitigation measures are implemented.
