1.1                                      Introduction

This Environmental Impact Assessment (EIA) Report addresses the potential environmental impacts associated with the construction and operation of aa  project entitled “Renewable Energy by a Wind Turbine System on Lamma Island (hereinafter referred to as the Project). 

The Project is classified as a Designated Project by virtue of Item D.1 of Part I of Schedule 2 (ie public utility electricity power plant) under the Environmental Impact Assessment Ordinance (Cap. 499) (EIAO). 

This report has beenis prepared by ERM-Hong Kong, Limited (ERM) in association with, and on behalf of, The Hongkong Electric Co Ltd (HEC), in accordance with the EIA Study Brief (No. ESB-112/2004) and the Technical Memorandum of the Environmental Impact Assessment Process (EIAO-TM).  The Study Area for the Project is presented in Figure 1.1.

1.2                                      Background

The Hongkong Electric Co Ltd (HEC) is committed to providing a high quality power supply to its customers with due care for the environment.  Recognizing the importance of sustainable development, HEC is proposing to install a wind turbine of capacity ranging from 600 to 850kW as a demonstration project to utilize wind energy for renewable power generation on Lamma Island, Hong Kong.

Following the completion of a 12-month wind power monitoring exercise onat Lamma Island in November 2002, a wind atlas was developed to assess the wind potential of Lammathe  iIsland.  A number of areas were identified as having wind power density over 150W/m2, equivalent to thean  average wind speed of about 5.5m/s, and generally considered suitable for wind energy utilization.  The existing power supply to Lamma Island residents and businesses is by means of through 11kV power lines, transformer pillars and low voltage distribution cables from the existing Lamma Power Station.

The wind turbine is proposed to be located at Tai Ling Tsuen (Figure 1.1) and the output will be connected to the existing power grid for supplying renewable energy to Lamma Island residentsHEC customers.  The operation of the wind turbine will be monitored and controlled through a central monitoring system located in a control room of the Lamma Power Station.  The wind turbine site will be unmanned and will only require attendance of operational personnel during emergency or routine maintenance (or in emergency).

1.3                                      Purpose and Objectives of this EIA Report

The purpose of the EIA is to provide information on the nature and extent of environmental impacts arising from the construction and operation of the Project and related activities that take place concurrently, to contribute to decisions on:

·           The overall acceptability of any adverse environmental consequences that are likely to arise as a result of the Project;

·           The conditions and requirements for the detailed design, construction and operation of the Project to mitigate against adverse environmental consequences wherever practicable; and

·           The acceptability of residual impacts after the proposed mitigation measures are implemented.

The detailed requirements of the EIA Study are set out in the EIA Study Brief.  The objectives of the EIA Study are:

i.          To describe the Project and associated works and phases of development together with the requirements and environmental benefits for carrying out the Project;

ii.        To provide information on the consideration of alternative sites to avoid and minimize the potential adverse environmental impacts, and to provide justifications and constraints for selecting the proposed option and to describe the part environmental factors played in the selection process;

iii.      To identify and describe the elements of the community and environment likely to be affected by the Project and/or likely to cause adverse impacts to the Project, including both the 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 losses or damage to flora, fauna and natural habitats;

vi.      To identify and quantify any potential landscape and visual impacts and to propose measures to mitigate these impacts;

vii.    To identify the negative impacts and propose the provision of mitigation measures so as to minimize pollution, environmental disturbance and nuisance during construction and operation of the Project;

viii.  To investigate the feasibility, practicability, effectiveness and implications of the proposed mitigation measures;

ix.      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 phases of the Project in relation to the sensitive receivers and potential affected uses;

x.        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;

xi.      To identify constraints associated with the mitigation measures recommended in the EIA study, as well as the provision of any necessary modification; and

xii.    To design and specify the environmental monitoring and audit requirements to ensure the effective implementation of the recommended environmental protection and pollution control measures.

As specified by the EIA Study Brief, the EIA has addressed the following key environmental issues associated with the construction and operation of the Project.

·           The potential noise pollution impacts on nearby sensitive receivers during construction and operation of the Project;

·           The potential ecological impact arising from the construction and operation of the Project, including loss of habitats and disturbance to wildlife, and the potential risk to any animal(s), especiallyincluding  birds(s,) during the operation of the wind turbine system;

·           The potential landscape and visual impacts on existing and planned sensitive receivers during the construction and operation of the Project; and

·           The potential air and water quality impacts during the construction stage of the Project.
