EXECUTIVE SUMMARY

The Project “Landslide Preventive Works at Po Shan, Mid-levels – Design and Construction (Natural Terrain Risk Mitigation Works)” (hereafter called “the Project”) includes the installation of about 700 numbers of soil nails and about 60 numbers of raking drains on the natural terrain within the concerned area.

China State – China Railway Joint Venture (CCJV) was commissioned as the Contractor of the Project. ENSR Asia (HK) Ltd. was employed by CCJV as the Environmental Team to carry out the EM&A programme.

The impact environmental monitoring and audit for the Project includes the air quality, noise, ecology, landscape and visual monitoring. The construction of the Project and the EM&A programme commenced on 1 April 2008.

This report documented the findings of EM&A works conducted in the period between 1 and 30 April 2008. As informed by the Contractor, construction activities in the reporting period were:

1.1 Future Key Issues

The weather in the forthcoming month is expected to be wet and windy. The Contractor should provide preventive measures to prevent any muddy runoff, such as proper collection and treatment of the runoff and provide a functional temporary drainage system in site.

It is also recommended to implement all necessary preventive measures to avoid oil leakage on ground / soil, such as provision of drip trays for all oil drums / chemical containers. In the event of oil leakage, the Contractor should properly remove the contaminated soil and dispose of as chemical waste. Construction waste and general refuse should be properly collected and disposed of.
