Introduction
This is the twenty-fourth
monthly Environmental Monitoring and Audit (EM&A) report prepared by
Maunsell Environmental Management Consultants Limited (MEMCL), which changed
the name to ENSR Asia (HK) Ltd. (ENSR) on 1 May 2007 for the “Temporary
Construction Waste Sorting Facility at Tseung Kwan O
Area 137” (the Project). This report documents the findings of EM&A Works
conducted during the impact period in October 2007 for Tseung
Kwan O Area 137.
As advised by the
Contractor, the project commenced on 12 November 2005. The construction activities in October 2007
were:
l
Operation
of Construction Waste Sorting Facilities (CWSF) by mechanical sorting plant;
l
Modification
of conveyor belt of mechanical sorting plant;
l
Maintenance
of haul road surface; and
l
Modification
of mist blower at Red Zone.

complaint, non-compliances or prosecutions were received in the reporting
month.
Permits and Licences

Environmental Site Inspection
There
were 4 site inspections conducted in October 2007. Due to the dry weather
conditions, fugitive dust was occasionally observed during dumping and manual
sorting of non-inert waste and during vehicle movement along the haul road in
Area A. Improving the water spraying at the non-inert waste stockpile and to
provide longer water spraying time to the load of the trucks at the
weigh-bridge in Area B1 in order to maintain the load damp prior dumping in
Area A were recommended.
The
Contractor was reminded to prevent any silty
materials or waste from entering the trapezoidal channel by providing bunding along the banks of the channel. The Contractor was
also reminded to properly store the chemicals on site to prevent spillage.
Future Key Issues
The weather is expected
to be dry and windy in the forthcoming month and as such, the Contractor should
provide preventive measures to maintain sufficient dust suppression
measures for vehicle movement along haul roads and during dumping and manual
sorting of non-inert waste. It is recommended to implement
sufficient mitigation measures to eliminate dust generation from dumping and
sorting activities.
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 and placement
of tarpaulin sheets on the ground during maintenance of equipment on site. In
the event of any oil leakage problem, the Contractor should properly remove the
leaked oil and handle the contaminated soil as chemical waste.
