Breaches of Action and Limit
Levels
There was no action / limit level exceedance recorded for 1-hour and
24-hour TSP monitoring.
In the reporting quarter, all noise level recorded complied with the
limit level.
Complaint, Notification of
Summons and Successful Prosecution
EPD
referred two complaints from residents nearby Po Shan
Mansions, regarding construction dust emission from the slope work at Po Shan Road in May
2009. Through on-site investigation, construction dust could potentially be
generated from soil nail drilling works of the Project. Although
all the 1-hr and 24-hr TSP monitoring results in May 2009 did not exceed the
Action levels, the Contractor was recommended to
improve mitigation measures to prevent dust emission as far as possible. EPD
had inspected the site on 22 May 2009 and had no adverse comment on the dust
control measures carried out on site. During follow-up site inspections by ET,
enhanced mitigation measures were taken by the Contractor and no significant
construction or fugitive dust was observed.
There was no notification of summons and successful prosecution received
in the reporting quarter.

Major noise sources during the noise monitoring included the
construction activities from the Project and another project under the same
contract (concurrent project) carried out in the vicinity and nearby traffic
noise.
Ecology
3.9
Ecological monitoring was
carried out twice a month by a suitably qualified local ecologist to check on
the health and condition of the plant species of conservation interest. Six
ecological monitoring were conducted in the reporting quarter.
3.10
A total of 13 plant species of
conservation interest (i.e. V001 to V013) were identified within the area
during an earlier Detailed Vegetation Survey conducted under this Project.
3.11
Three individuals of vegetation
of conservation interest in Group V015, V016 and V017 had been identified and tags
tied back during the 28 April 2009 visit.
The Contractor agreed to fence off two of the individuals which were
located outside the existing fence-off area.
The Contractor was also advise to erect a clear sign notable to all the
construction workers and restrict any unauthorized entry to the area.
3.12
Another two vegetation of
conservation V018 and V035 could not be located during the monitoring visits, The
Contractor advised the concerned vegetation were probably covered up under the
temporary storage platform and scaffolding, the Contractor agreed to identify
the missing individual once the platform has been removed from the site.
3.13
Some vegetation and plant
species of conservation interest located near soil nailing work areas were
densely covered with soil and dust.
3.14
Hardened grout was found in the
natural habitat near the Project area.
To prevent the plant from being affected by grout leakage and muddy site
run-off, the Contractor was reminded to remove any grout from the natural
habitat as soon as possible and add sand bags around the hardened grout.
3.15
Sign of oil / lubricant
spillage was observed from soil nailing machine on the nearby vegetation. The Contractor was recommended to remove any
soil nailing machine from the vegetation.
3.16
Part of the plant species of
conservation interest were not properly fenced off or tagged, particularly in
works area above Row AD. The Contractor
was advised to fence off and label the vegetation properly with a clear sign
notable to all the construction workers and restrict any unauthorized access to
the area.
3.17
During monitoring visit on 2 June 2009, a number of vegetation of
conservation interest were missing from site, including V057, V058, V063, V056,
V054, V055, V052, and V042. And some
others were not fenced off, including V065, V051, V053, V048, V049, V050, V043,
V044, V045, V046, and V047. The missing
vegetation were subsequently found and tagged in 23 June 2009 visit apart from
V054. The eleven unprotected were also
fenced off.
3.18
A vegetation of conservation
V018 was found to be in very poor condition.
3.19
Soil of natural terrain along
an access road (near Row AH) was not well covered.
Landscape
and Visual
3.20
Bi-weekly landscape and visual
audit was conducted by a Registered Landscape Architect (RLA) to monitor the
implementation of landscape and visual mitigation measures. Seven landscape and
visual audits were conducted in the reporting quarter.
3.21
The Contractor had rectified
the tree ID numbers on site, with approximately 60% completed. The Contractor was reminded to finish the
rectification of missing tree ID numbers works for the remaining existing trees
as soon as possible.
3.22
It was noted that compensatory
planting proposal for the replacement of dead tree T611 was outstanding. The Contractor was recommended to seek
Engineer’s agreement on the replacement planting as soon as possible.
3.23
It was noted that the
Contractor’s clarification of the status of existing trees T516, T517, T666,
and T698 located immediately outside of the works boundary was
outstanding. The Contractor was reminded
to provide necessary information as soon as possible.
3.24
It was observed that
construction materials were stock piled against the trunks of 2 existing
trees. The Contractor was requested to
clear the material away from the tree as soon as possible.
3.25
The Contractor had removed the
termite infected dead tree T511 at the corner of footpath stair. The Contractor had also removed the tree with
rotten trunk base located near existing tree T534. However, removal of dead tree T534 itself was
outstanding, which was also infected by termites. The Contractor was also
reminded to remove the dead tree T534 which had leaned against existing tree
T538.
3.26
It was still observed that the
termite infected dead tree T534 along the footpath stair was not removed. The Contractor was reminded to urgently
remove the infected dead tree for consideration of safety of the workers and
the public in future.
3.27
It was observed that electrical
cables were strung overhead and hanged from tree branches. The Contractor was requested to remove the
electrical cables away from the trees as soon as possible.
3.28
It was observed that the
Contractor had tied safety ropes around the base of several existing
trees. The Contractor was reminded that
the practice was not acceptable and was requested to remove the ropes as soon
as possible.
3.29
It was observed that soil was
compacted against the base of a small existing tree on the upper slope side and
used as passage area. The Contractor was
reminded the practice was unacceptable and the compacted soil is to be removed
and constructed with proper passage without affecting the existing tree if
required.
3.30
It was observed that the
Contractor had tied ropes to the base of existing tree T668 for support of the
large air hose. The Contractor was
requested to remove the rope from the base of the tree.
3.31
It was observed that an
existing tree on the slope which had partially grown above an existing boulder was undermined by the recent removal of the boulder due to
engineering safety considerations. The
tree root system is now partially undermined and exposed, which would lead to
dry-out and possible collapse during strong winds and typhoons. The Contractor was recommended to back-filled
the pit and compact the slope surface area to stabilize the tree.
3.32
It was observed that the
make-shift materials conveyor system had its edge board encircled an existing
tree, with the tree trunk being easily damaged by the conveyor ‘boat’. The Contractor was requested to rectify the
edge board to ensure that conveying of materials would not damage the tree
trunk.
Environmental Site
Inspection
3.33
There were 13 site inspections
conducted in the reporting quarter to monitor the implementation of proper
environmental pollution control and mitigation measures for the Project. The
major concerns for the Project are air quality, noise, water quality, waste
management, ecology and landscape and visual. Observations recorded are

Advice on Solid and liquid
Waste Mangement Status
4.1
The Contractor has registered
as a chemical waste producer for this Project. The Chemical Waste Storage Area
located at the Contractor’s site office area was properly maintained in the
reporting quarter.
4.2
As advised by the Contractor, 61.51 ton of inert
C&D waste was disposed offsite to Chai Wan and 74.42 ton of non-inert
C&D waste was disposed offsite to SENT landfill in the reporting period. Also
20kg of chemical waste was collected by licenced waste collector in the
reporting quarter. C&D waste generated was reused on site as much as possible.
Summary
of Exceedances and Review of the Reasons for non-compliance
5.1
There was no 1-hr TSP, 24-hr
TSP and noise exceedance recorded in the reporting quarter.
6.1
EPD referred two complaints,
one on 15 May 2009 and one on 19 May 2009, from residents nearby Po Shan Mansions, regarding construction dust emission from
the slope work at Po Shan Road.
Through on-site investigation on 19 May 2008, construction dust could
potentially be generated from soil nail drilling works of the Project. Although
all the 1-hr and 24-hr TSP monitoring results in May 2009 did not exceed the
Action levels, the Contractor was recommended to improve mitigation measures to
prevent dust emission as far as possible, such as enhancement of tarpaulin
enclosures and watering facilities, during soil nail drilling works. EPD had
inspected the site on 22 May 2009 and had no adverse comment on the dust
control measures carried out on site. During follow-up site inspections by ET
on 26 May 2009, enhanced mitigation measures were taken by the Contractor and
no significant construction or fugitive dust was observed.
6.2
No notification of summons and
prosecution was received in the reporting quarter. Table 6.1 summarized the
complaint, summons and successful prosecution received in the reporting period.
