Introduction
This is the nineteenth
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 May 2007 for Tseung Kwan O Area 137.
As advised by the Contractor, the project
commenced on 12 November 2005. The construction activities in May 2007 were:
l
Operation
of Construction Waste Sorting Facilities (CWSF) by mechanical sorting plant;
l
Enhanced
dust suppression system at Portion A; and
l
Safety
barrier at VGF end-tipping platform.
Environmental Monitoring Works
Air Quality
1-hr
TSP Monitoring
All the monitoring data
complied with the
24-hr
TSP Monitoring
One limit level
exceedance was recorded in May 2007. The exceedance was concluded partially due
to the Project. One additional monitoring was carried out on 16 May 2007 and
the result did not exceed the action / limit level.
Complaints, Non-compliance and Prosecutions
No environmental complaint,
non-compliances or prosecutions were received in the reporting month.
Permits and Licences
No new permit or license
was obtained in the reporting month.
Environmental Site Inspection
There were 5 site
inspections conducted in May 2007. Due to the occasion dry weather conditions,
fugitive dust was occasionally observed during transferring and dumping of
materials in Area A and along the haul road during dry weather.
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 wet and windy in the forthcoming month and as such, the Contractor should provide
preventive measures to prevent surface runoff, such as bunding
around the site boundaries, to ensure that a functional temporary drainage
system is in place around the site. The Contractor should also maintain
sufficient
dust suppression measures for vehicle movement along haul roads and during
sorting activities. 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.
