conducted during the impact period in March 2006 for Tseung
Kwan O Area 137.
As advised by the Contractor, the project

Installation of surveillance system and public address
system;
l
Construction of Engineer’s site office and car parking area;
l
Operation
of Construction Waste Sorting Facilities (CWSF) by manual sorting; and
l
Installation of steel fence along the access road.
Environmental Monitoring Works
Air Quality
1-hr TSP Monitoring
All the monitoring data complied
with the
24-hr TSP Monitoring
There were three limit level exceedances
recorded on 13, 24 and 30 March 2006 at monitoring station TKO1. Exceedances recorded were considered related to the
Project.
Complaints,
Non-compliance and Prosecutions
No environmental complaints,
non-compliances or prosecutions were received in the reporting month.
Permits and
Licences
No new permit or license was
obtained / applied in the reporting month.
Environmental
Site Inspection
Site inspections were carried out
weekly by the ET to ensure proper implementation of environmental mitigation
measures specified in the EM&A Manual and compliance with relevant
environmental legislation.
There were 5 site inspections
conducted in March 2006. Due to the dry weather condition, fugitive dust was occasionally
observed along the haul road. Dust was also generated during transferring and
dumping of materials. Water spraying should be provided to all dusty operation
and the water spraying frequency should be increased.
The trapezoidal channel was filled
with waste, the Contractor agreed to remove all waste in the channel by April
2006. Water ponding was found outside the site office
after rain events and stagnant water was found inside the trapezoidal channel
at Area A. The Contractor was reminded to clear the stagnant water. Rubbish
scattered in Area A should also be cleared.
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 ensure functional temporary drainage system is in place around
the site and to 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
emission from dump truck traffic 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.
