1.                       INTRODUCTION

1.1                   Project Background

1.1.1             The Transport Department (TD) has reviewed the traffic conditions of Tsuen Wan Road (TWR) near Kwai Tsing Interchange (KT I/C) and considered that a section of the southbound carriageway of TWR between KT I/C and Kwai Chung Road (KCR) would deteriorate in the future years due to congestion that would occur during peak hours.  TD considers that there is a need to implement the Project to improve the road section to cope with the future traffic growth, and the scope comprises the following principal works elements:

(a)           Provision of an additional traffic lane for the southbound traffic between KT I/C upramp and KCR (Bridge H);
(b)          Modification of existing slip roads (Bridge G); and
(c)           Associated environmental mitigation measures, utility diversion, street lighting, traffic aids, traffic and control surveillance, drainage works, landscaping works and other related works.

1.1.2             AECOM Consulting Services Limited (formerly URS Hong Kong Ltd or Scott Wilson Ltd) was commissioned by the Civil Engineering and Development Department (CEDD) of the Government of the Hong Kong Special Administrative Region to undertake the investigation stage of Flyover from Kwai Tsing Interchange up-ramp to Kwai Chung Road (‘the Project’ refers hereinafter) under Agreement No. CE 8/2012 (HY).

1.1.3             The Project is a Designated Project under the Environmental Impact Assessment Ordinance (EIAO).  An application (No. ESB-242/2012) for an Environmental Impact Assessment (EIA) Study Brief under section 5(1)(a) of the EIAO was submitted by the CEDD on 29 February 2012 with a Project Profile (No. PP-459/2012) for the Project.  An EIA Study for the Project has been undertaken as part of the Assignment, in accordance with the EIA Study Brief (No. ESB-242/2012) which was issued in April 2012 and the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM).

1.2                   Designated Projects under EIAO

1.2.1             The new additional traffic lane (Bridge H) is a designated project under Item A.8 of Part I, Schedule 2 of the EIAO: “A road or railway bridge more than 100m in length between abutments”. 

1.2.2             Regarding the modification of existing slip road (Bridge G), it would not cause any environmental impact likely to affect existing or planned community, or environmental sensitivity uses in the vicinity.  It is because the modification of Bridge G would not increase any traffic lane and it would divert some traffic flow from Bridge G to Bridge H, and that traffic noise impact and vehicular emission during operation phase would be slightly improved in considering of Bridge G itself in view of the reduced traffic.  Hence, it would not have any increase in pollution emissions or discharges or waste generation likely to violate guidelines or criteria stipulated in EIAO-TM without mitigation in place.  Therefore, referring to section 6 of EIAO-TM, Bridge would not constitute any “material change” under the EIAO.  As Bridge G would not induce adverse noise impact during operation phase in view of the reduced traffic, mitigation measures for Bridge G is anticipated not necessary.

1.3                   Purpose of the EIA Study

1.3.1             The purpose of the EIA Study is to provide information on the nature and extend of the environmental impacts from the construction and operation of the Project and associated mitigation, and related activities that take place concurrently.  This information will contribute to decisions on:

·      The acceptability of 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; and

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

1.4                   Objectives of this EIA Study

1.4.1             The EIA Study has been conducted and completed in accordance with the requirements of the EIA Study Brief under the EIAO and the guidelines on assessment methodologies provided in the EIAO-TM.  The EIA Report has been prepared:

(a)           to describe the Project and associated works together with the requirements and environmental benefits for carrying out the Project;

(b)          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;

(c)           to identify and quantify emission sources and determine the significance of impacts on sensitive receivers and potential affected uses;

(d)          to identify any systematically evaluate any potential landscape and visual impacts and to propose measures to mitigate these impacts;

(e)           to identify any negative impacts on sites of cultural heritage and to propose measures to mitigate these impacts;

(f)           to propose the provision of infrastructure or mitigation measures to minimize pollution, environmental disturbance and nuisance during construction and operation of the Project;

(g)          to investigate the feasibility, effectiveness and implications of the proposed mitigation measures;

(h)          to identify, predict and evaluate the residual (i.e. after practicable mitigation) environmental impacts 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;

(i)            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 residual environmental impacts and cumulative effects and reduce them to acceptable levels;

(j)            to design and specify the environmental monitoring and audit requirements; and

(k)          to identify any additional studies necessary to implement the mitigation measures or monitoring and proposals recommended in the EIA report.

1.5                   Approach to EIA Study

1.5.1             The following general principles and approaches for evaluating the potential environmental impacts were adopted in this EIA study:-

Description of the Environment

1.5.2             The characteristics of the existing environment were described for the identification and prediction of potential impacts which are likely to arise from implementing the Project.  Baseline environmental surveys were conducted where necessary and relevant reports / documents were reviewed to determine the existing environmental conditions on the Project site and in all surrounding areas likely to be affected by the Project.

Impact Prediction

1.5.3             Individual aspect assessments were undertaken in accordance with the relevant guidelines on assessment methodologies given in the EIAO-TM. 

Impact Evaluation

1.5.4             The predicted changes and effects resulting from the Project were evaluated with respect to the criteria given in the EIAO-TM and were in quantitative assessments as far as practicable.

Impact Mitigation

1.5.5             Mitigation measures have been identified and evaluated to avoid, reduce and remedy the impacts.  Priority was given to avoidance of impacts as a primary means of mitigation.  The effectiveness of the proposed mitigation was assessed and the residual environmental impacts were identified and considered for their acceptability.

1.5.6             An implementation schedule for the mitigation measures was prepared to identify when and where each mitigation measure is required, and to identify which parties are responsible for its implementation and where necessary, for its maintenance.

1.6                   EIA Study Scope

1.6.1             The environmental issues covered in this EIA study, as addressed in the EIA Study Brief (No. ESB-242/2012), are as follows:

·          Potential noise and air quality impacts from the construction and operation of the Project to sensitive receivers along or near the Project, taking into account the cumulative impact from the operation of existing roads in the vicinity of the Project;

·          potential water quality impact from the construction and operation of the Project on the relevant water system(s);

·          potential waste management issues and impacts arising from the construction and operation of the Project;

·          potential land contamination arising from land to be resumed for the Project;

·          potential landfill gas hazard on site during the construction and operation of the Project due to the former Gin Drinker’s Bay Landfill;

·          potential landscape and visual impacts during the construction and operation of the Project;

·          potential impacts on sites of cultural heritage from construction and operation of the Project; and

·          potential cumulative environmental impacts of the Project and associated works, through interaction or in combination with other existing, committed and planned projects in their vicinity, and that those impacts may have a bearing on the environmental acceptability of the Project.


1.7                   Public Engagement /Consultation

1.7.1             The Project was presented to the Transport & Traffic Committee (T&TC) and Community Affairs Committee (CAC) under Kwai Tsing District Council (KTDC) in December 2014 after consultation with Kwai Tsing District Office and on completion of TIA, DIA and draft EIA studies. The presentation was to introduce the proposed road alignment option, associated works, implementation programme, results of the TIA and EIA together with the mitigation measures, land resumption, and road crossing facilities to be affected during construction and operation stages. The Project was supported without opposition in the T&TC meeting, and no adverse comment was received from the CAC on the consultation paper circulated to CAC.

1.7.2             Early consultation with the neighbouring facilities that may be affected by the Project was conducted prior to the aforementioned presentation to T&TC in order to provide an opportunity for direct dialogue with the public having concerns on matters relating to the traffic, environment, and community services. Informal meetings were held with the representatives of Sin Ching Kindergarten, Lai King Catholic Secondary School, Lingnan Dr. Chung Wing Kwong Memorial Secondary School and Estate Management Advisory Committee of Lai King Estate, and the district councillors of Lai King/Hing Fong constituencies during November and December 2014.
