1                        INTRODUCTION

1.1                  Background to the Study

1.1.1            The Drainage Services Department completed the “Stormwater Drainage Master Plan Study in Sai Kung, East Kowloon and Southern Lantau” (DMP Study) in September 2000. The DMP Study identified deficiencies and flooding problems in the existing drainage systems in these three areas.  The Preliminary Project Feasibility Study (PPFS) Report for the drainage improvements in Southern Lantau was subsequently completed in March 2002 identifying the constraints, proposing preliminary development options and recommending further investigations and studies.

1.1.2            This Project, “Drainage Improvement in Southern Lantau – Investigation”, is part of the recommendations in the DMP Study for upgrading the existing drainage capacity in Southern Lantau.

1.1.3            Under this Project, part of the proposed drainage improvement works in Southern Lantau is a Designated Project under Schedule 2 Part I of the Environmental Impact Assessment Ordinance (EIAO) and requires an environmental permit under the EIAO for its construction and operation.  The Designated Project includes the drainage improvement works in Pak Ngan Heung River, Tai Tei Tong River, Luk Tei Tong River and Luk Tei Tong (2) River in the Mui Wo area. The locations of the Project are shown in Figure 1.1. 

1.1.4            An EIA Study for the Project has been undertaken in accordance with the EIA Study Brief No. ESB-101/2002 registered under the EIAO and the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM). 

1.1.5            The objective of this Executive Summary is to present the summary of the findings of the EIA Report.


1.2                  Purpose and Scope of the EIA Study

1.2.1            The purpose of the EIA study is to provide information on the nature and extent of potential environmental impacts arising from the construction and operation of the Project, and to contribute to decisions on the overall environmental acceptability of the Project after the implementation of environmental mitigation measures.  Environmental issues covered include noise, air quality, water quality, waste management, ecology and cultural heritage.
