Executive Summary
The Central Reclamation Phase III (CRIII) Works,
Contract No. HK 12/02, was awarded to Leighton China State Van Oord Joint
Venture (LCSVO-JV) by the Civil Engineering and Development Department (CEDD). (Previously
called the Territory Development Department before merger with the Civil
Engineering Department on

of Summons and Prosecutions
There were no
notifications of summons or prosecutions received during this reporting quarter.
EPD
communicated with the ET that a report of muddy water near the works area
of FRAE was received on
Subsequent to investigation by the Contractor, they confirmed that no
marine works near the eastern seawall was conducted on
Site Inspection and Audit
Weekly environmental site inspections were carried out during this
quarter. Minor deficiencies noted during
the site inspections were rectified by the Contractor upon receipt of
notification. The observations and findings are outlined below:
The silt curtain at Culvert F was observed damaged (due to recent typhoon on 4th August 09). The Contractor has arranged for the silt curtain at Culver F to be replaced.
A skip at the works area near Pier 10 contained construction waste and general refuse. The surrounding area was untidy. The Contractor was reminded to segregate different types of waste to enhance proper disposal and recycling and to tidy up the surrounding area.
Dark smoke emission was observed from the excavator near the RE office. The contractor was reminded to undergo maintenance of site equipment to prevent dark smoke emission.
EPD communicated with
the ET that a report of muddy water near the works area of FRAE was
received on
Subsequent to investigation by the Contractor, they confirmed that no
marine works near the eastern seawall was conducted on
N.A.
Noisy Activities was observed in the works area of former Queen’s Pier. Two sheet piling activities were concurrent operated during site inspection. Contractor was reminded to schedule the construction activities at the former Queen’s Pier carefully. Concurrent operation of sheet piling activities should be avoided. Short breaks between noisy activities should also be taken as far as practicable.
A part of the access roads in FRAE were observed dry during inspection. The Contractor was reminded to ensure that access roads are watered appropriately especially in dry weather.
N.A.
N.A.
Rubbish was trapped by the silt curtain at the south-east corner at FRAE workarea. The Contractor was reminded to collect the rubbish which trapped by silt curtain regularly.
N.A.
The silt curtain at the mouth of Culvert F was seen to have detached from the side during site inspection. The Contractor was reminded to ensure the silt curtains are installed properly.
Small amount of debris was seen to have accumulated at the inner layer silt curtain further upstream of Culvert F. The Contractor was reminded to remove debris caught at silt curtains regularly.
Dark smoke emission was found from air compressor in the FRAW workarea. The Contractor was reminded to maintain and inspect equipment appropriately to prevent smoke emission.
Muddy water discharge was observed from an outfall at the CR-6 works area. Discharge from this outfall is from external sources and as such, is not related to the Project construction works.
A container of unidentifiable chemicals was placed
on the ground without a drip tray at the FRAE works area. The contractor was reminded
to label and store chemicals appropriately.
The Chemical Waste Storage Area at FRAE workarea
was found that have not enough spacing between the top of enclosure wall and
the ceiling for ventilation. The contractor was arranged the workman to make the ventilation spacing
for Chemical Waste Storage Area.
The leakage of muddy water from the soil bund was
found in the works area of FRAW near the mouth of culvert F during site
inspection. The contractor was rebuilt the soil bund immediately to stop the
leakage of muddy water. The contractor was arranged to excavate temporary
trench between works area and culvert F for the future precaution.

A statistical
analysis (presented in Annex I) of the suspended solids
monitoring results found that the quarterly mean is significantly less than 1.3
times of the ambient mean recorded during the baseline period. This indicates that the Project construction
works did not cause adverse impacts during the reporting period with respect to
the baseline condition.
No non-compliance with regard to site environmental audit was recorded
during the reporting period.
The
Contractor has implemented the following measures to prevent air and water
quality impacts:
·
Contractor has implemented their Drainage Management
Plan to Control Site Run-off for the wet season – actions completed and
underway include: repair and improvement of existing bunds/sandbags on the edge
of the reclamation; installation of additional bunds; compaction of soil
surface and paths where possible to prevent erosion, creation of drainage
channels and soak pits;
·
Provision of additional settlement tanks to remove
suspended solids from discharge waters;
·
Provision of catch pits to collect spill over from wheel
washing facilities and increased frequency of cleaning of catch-pits; and
·
Water browsing of haul roads and other areas of the
site and covering of stockpiles.
No environmental enquiries were received during this reporting quarter.
No environmental complaints were received
during this reporting quarter.
EPD communicated with the ET that a report of muddy water near
the works area of FRAE was received on
Subsequent to
investigation by the Contractor, they confirmed that no marine works near the
eastern seawall was conducted on
There was no record of environmental complaints during this reporting
quarter.
There
were no notifications of summons and prosecutions during this reporting
quarter.
During the environmental site inspections conducted within this
reporting quarter, no non-compliances were noted and no prosecutions were
received during this reporting quarter.
No exceedance in TSP level was recorded at the two monitoring stations during this reporting quarter.
