1.                  INTRODUCTION

 

Background

 

1.1               Based upon on-going developments along the Castle Peak Road in Yau Kom Tau, Sham Tseng and Tsing Lung Tau, it is anticipated that the road network in the area will become increasingly overloaded by the year 2011. Castle Peak Road is at present a two-lane single carriageway, with narrow footways at discrete locations and is generally characterised by sub-standard geometry and frequent entry / egress points offering insufficient visibility. The exception to this is through the centre of Sham Tseng, where the road is already built to a dual two-lane carriageway standard.

 

1.2               As a result of this, the Government has decided that, in order to enhance the level of service for the increasing number of users, the road needs to be improved to cope with traffic growth predicted by the year 2011. Meinhardt Halcrow Joint Venture (MHJV) has been commissioned by Highways Department (HyD) under Agreement CE 1/96 to, in broad terms, review the findings, conclusions and recommendations of the Feasibility Study, complete the detailed design of the project taking into account any modifications noted during the review, prepare the pre-qualification and tender documents and implement the project.

 

1.3               China State Construction Engineering (Hong Kong) Ltd. (CSHK) was appointed as the Contractor under Contract No. HY/99/19 – Middle Section to carry out the construction for “Castle Peak Road Improvement between Ting Kau and Sham Tseng, Tsuen Wan” (hereafter called the “Project”).

 

1.4               Maunsell Environmental Management Consultants Limited (MEMCL) was employed by CSHK as the Environmental Team (ET) to undertake EM&A works for the Project. In accordance with the EM&A Manual, environmental monitoring of air quality, noise, water quality, landscape and visual, and environmental site inspections would be required for this Project.

 

1.5               Under the Environmental Impact Assessment (EIA) on the Feasibility Study for the Castle Peak Road Improvements completed in 1996, reclamation at Sham Tseng East was defined as designated works. An Environmental Permit (EP No.: EP-095/2001) was issued under the EIAO on 29 March 2001.

 

1.6               A few minor comments were received from EPD on the Marine Water Quality Baseline Monitoring Report (Rev.2) on 27 August 2003. The upstream control stations of MW5 & MW6 had been revised to MR5 & MR6 while there would not be any upstream control station for WFCZF1 during mid-flood tide. The revised pages were submitted after the verification of the IC(E) to all the relevant parties on 1 September 2003.

 

Scope of Report

 

1.7               This is the fifty-third monthly Environmental Monitoring and Audit (EM&A) Report under Contract HY/99/19 – Castle Peak Road Improvement between Ting Kau and Sham Tseng. This report presented a summary of the environmental monitoring and inspection works, list of activities, and mitigation measures carried out by the ET for the Project for November 2006.
