1.1.1
The
Drainage Master Plan Studies for the Yuen Long, Kam Tin, Ngau
Tam Mei and Tin Shui Wai Drainage Basin (YLDMP) were completed in 1998. The
majority of the improvement works in Yuen Long and Kam Tin recommended under
the YLDMP Study have been completed. Since completion of the DMP Studies, there
have been changes in developments within the areas and new development
proposals and town planning studies were commissioned. In addition, some new
flooding complaints were received at the upstream areas of the drainage basins,
indicating that further improvement to the drainage systems was required.
1.1.2
DSD
commissioned the “Review of Drainage Master Plans in Yuen Long and North
Districts – Feasibility Study” (the Review Study) in 2008 so that the new
development scenarios could be incorporated and the
effectiveness of the previously recommended works could also be assessed. The
Review Study completed in end 2011 identified that some areas in Yuen Long
District could not meet the required flood protection level according to the
latest land use changes and future developments taking into account various
factors, including sedimentation at the downstream main channels, mangrove
growth at river estuaries, updated extreme sea level statistics at Tsim Bei Tsui and projected Climate Change impacts, in the
hydraulic analysis. To account for the severity and extent of possible flooding
and the works implementation time, the Review Study proposed drainage
improvement works in Yuen Long District.
1.1.3
Atkins
China Ltd (ACL) was commissioned by DSD in November 2013 to undertake an
Investigation, Design and Construction Consultancy entitled “Agreement No. CE
22/2013 (DS) Drainage Improvement Works in Yuen Long, Stage 1 – Investigation,
Design and Construction” (hereinafter called the Assignment). The Project
comprises construction of drainage improvement works to four villages (namely
Sung Shan New Village, Tai Wo, Lin Fa Tei and Ha Che)
including landscaping, waterscaping, utilities
diversion, temporary traffic arrangements, re-provisioning / improvements to
existing dry weather flow intercepting system and any other works incidental to
the completion of the Project.
1.1.4
An
Environmental Impact Assessment (EIA) Study Brief (ESB-279/2014) for four
villages namely Ha Che, Tai Wo, Lin Fa Tei and Sung
Shan New Village which is a designated project was issued by the Environmental
Protection Department (EPD) on 14 October 2014. According to the Study Brief,
an Environmental Monitoring & Auditing (EM&A) Manual is required for
these four villages.
1.1.5
The
site location plan is shown in Figure 1.1 and the locations of the
proposed drainage improvement works at these four village are detailed in Figures
1.2, 1.3, 1.4A,
1.4B, 1.5A and 1.5B.
1.2.1 The
proposed drainage improvement works are planned to commence in 2022 and
completion in 2025.
1.3.1
The
purpose of this EM&A Manual (hereafter refer to as the “Manual”) is to
guide the set up of an EM&A programme to ensure
compliance with the recommendations in the EIA study covering the drainage
improvement works near four villages in Yuen Long, to assess the effectiveness of the
recommended mitigation measures and to identify any further need for additional
mitigation measures or remedial action.
This Manual outlines the monitoring and audit programme for both the
construction and operational phase of the Project. It aims to provide systematic procedures for
monitoring, auditing and minimising environmental impacts associated with the
construction and operational phases.
1.3.2
This
Manual provides specific information, guidance and instruction to personnel in
charged with environmental responsibilities and undertaking environmental
monitoring and auditing works for drainage improvement works near four
villages in Yuen Long. It also
provides systematic procedures for monitoring, auditing, and minimising environmental
impacts associated with the construction activities.
