Project Title : A COMMERCIAL SCALE WIND TURBINE
PILOT DEMONSTRATION AT HEI LING CHAU
(hereinafter known as the "Project")
Name of Applicant : CASTLE PEAK POWER CO., LTD.
(hereinafter known as the "Applicant")
1. BACKGROUND
1.1 An application (No. ESB-145/2006) for an Environmental Impact Assessment (EIA) Study Brief under section 5(1)(a) of the Environmental Impact Assessment Ordinance (EIAO) was submitted by the Applicant on 24 March 2006 with a project profile (No. PP-283/2006) (the Project Profile).
1.2 The proposed Project is to construct and operate a 800kW to 1.3MW wind turbine and its associated equipments at Hei Ling Chau. The site location is shown in Figure 2.6e of the Project Profile and is reproduced in Appendix A in this study brief. The development and operation of the proposed Project will comprise the following major activities :
(i) Site Formation;
(ii) Upgrading of existing roads and/or formation of temporary accesses for delivery of construction materials and equipments;
(iii) Pre-bored H-piling and construction of reinforced concrete foundation for the wind turbine;
(iv) Erection of wind turbine tower and installation of nacelle and rotor blades;
(v) Installation of step up transformer and substation;
(vi) Installation of transmission cables between the substation and the 11kV supply grid; and
(vii) Testing, commissioning and operation of the wind turbine system.
1.3 The Project is a designated project under Item D.1 Part I Schedule 2 of the EIAO, i.e. public utility electricity power plant.
1.4 Pursuant to section 5(7)(a) of the EIAO, the Director of Environmental Protection (the Director) issues this EIA study brief to the Applicant to carry out an EIA study.
1.5 The purpose of this EIA study 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 Project and the associated activities of the Project;
(ii) the conditions and requirements for the detailed design, construction and operation of the Project to mitigate against adverse environmental consequences; and
(iii) the acceptability of residual impacts after the proposed mitigation measures are implemented.
1.6 It should be noted that this EIA study brief is for a wind turbine demonstration project to utilize wind energy for power generation on Hei Ling Chau Island, rather than a permanent large scale wind farm, and the types and scope of issues for a permanent large scale wind farm are unlikely to be the same as for the demonstration project. The scope of issues and the study approach set out in this study brief are for the demonstration project only.
2. OBJECTIVES OF THE EIA STUDY
2.1 The objectives of the EIA study are as follows:
(i) to describe the Project and associated works together with the requirements and environmental benefits for carrying out the Project;
(ii) to provide information on the consideration of alternatives to avoid or minimize the potential environmental impacts to the ecological sensitive areas and other sensitive uses; to compare the environmental benefits and dis-benefits of each of the different options; to provide reasons for selecting the preferred option(s) and to describe the part of environmental factors played in the selection;
(iii) to identify and describe elements of community and environment likely to be affected by the Project and/or likely to cause adverse impacts to the Project, including natural and man-made environment and the associated environmental constraints;
(iv) to identify and quantify emission sources and determine the significance of impacts on sensitive receivers and potential affected uses;
(v) to identify and quantify any potential landscape and visual impacts and to propose measures to mitigate these impacts;
(vi) to identify and quantify any potential losses or damage and other potential impacts to flora, fauna and natural habitats and to propose measures to mitigate these impacts;
(vii) to identify any negative impacts on sites of cultural heritage and to propose measures to mitigate these impacts;
(viii) to propose the provision of mitigation measures to minimize pollution, environmental disturbance and nuisance during construction and operation of the Project;
(ix) to investigate the feasibility, practicability, effectiveness and implications of the proposed mitigation measures;
(x) to identify, predict and evaluate the residual environmental impacts (i.e. after practicable mitigation) and the cumulative effects expected to arise during the construction and operation of the Project in relation to the sensitive receivers and potential affected uses;
(xi) to identify, assess and specify methods, measures and standards, to be included in the detailed design, construction and operation of the Project which are necessary to mitigate these environmental impacts and cumulative effects and reduce them to acceptable levels;
(xii) to investigate the extent of the secondary environmental impacts that may arise from the proposed mitigation measures and to identify constraints associated with the mitigation measures recommended in the EIA study, as well as the provision of any necessary modification; and
(xiii) to design and specify environmental monitoring and audit requirements to ensure the effective implementation of the recommended environmental protection and pollution control measures.

(v) Construction Noise Assessment
(a) The Applicant shall carry out assessment of noise impact from construction (excluding percussive piling) of the project during day time, i.e. 7 a.m. to 7 p.m., on weekdays other than general holidays in accordance with the methodology stipulated in paragraphs 5.3. and 5.4 of Annex 13 of the TM. The criteria in Table 1B of Annex 5 of the TM shall be adopted in the assessment.
(b) If the unmitigated construction noise levels are found to exceed the relevant criteria, the Applicant shall propose practicable direct mitigation measures (including movable barriers, enclosures, quieter alternative methods, re-scheduling and restricting hours of operation of noisy task(s)) to minimize the impact. If the mitigated noise levels still exceed the relevant criteria, the duration of the noise exceedance shall be given.

Regardless of the results of construction noise impact assessment for restricted hours, the Noise Control Authority will consider a well-justified Construction Noise Permit (CNP) application, once filed, based on the NCO, the relevant technical memoranda issued under the NCO, and the contemporary condition/situations of adjoining land uses and any previous complaints against construction activities at the site before making his decision in granting a CNP. This aspect should be explicitly stated in the noise chapter and the conclusions and recommendations chapter in the EIA report.

Specific reasons for not adopting certain direct technical remedies in the design to reduce the noise to a level meeting the criteria in the TM or to maximize the protection for the NSRs should be clearly quantified and laid down. The total number of dwellings and other noise sensitive element that will be benefited by the provision of direct technical remedies should be provided.
The total number of dwellings and other noise sensitive elements that will still be exposed to noise above the criteria with the implementation of recommended direct technical remedies shall be quantified.
In case where a number of the NSRs cannot be protected by the recommended direct technical remedies, the Applicant shall consider alternatives to reduce the impacts.
