5.2.2
Establishment period for the pitcher plants was completed
at the end of September 2016, the join site completion of Establishment period
visit with AFCD was undertaken on 23 September 2016 and the final pitcher plants
report was submitted to AFCD on early December 2016. Therefore
after 23 September 2016, only the integrity of the protection fence was checked
to fulfil the EIA requirement. During each inspection, the protection mitigation measures were
checking at the final receptor area to make sure no site activities was
undertaken inside the protection zone. Besides, no construction activities were observed to be carried
out at the surrounding of the final receptor area. The condition of chain link fence is good
and no repair or maintenance is required.
5.2.3
No matters the completion of Establishment period, the
Contractor should properly maintain the fencing along the receptor area to
avoid disturbance to the pitcher plants under the EIA requirement.
6.1.1
According to the EM&A Manual
requirements, regular inspection for heritage resource, Grave G1, shall be
audited by the ET at least once every week to ensure recommended mitigation
measures implemented during construction period. The aim of the survey is to
prevent any possible damage to the grave and to ensure the proposed mitigation
measures are implemented. The broad
scope of the audit will involve supervision of the following:
Ÿ
Non-contact effects of
the engineering works, such as vibration from pneumatic drills which could cause
damage, such as foundation or wall cracks and loosening of tiles or fixtures;
and
Ÿ
Contact between the historic
structures and equipment and materials associated with the engineering works.
6.1.2
Specifically, the
monitoring programme will entail the following tasks:
Ÿ
The extent of the agreed
works areas should be regularly checked during the construction phase to ensure
the buffer is being maintained; and
Ÿ
Ensure no stockpiling or
equipment storage is affecting the structure.
6.1.3
In the event of non-compliance
the responsibilities of the relevant parties is detailed in the Event/ Action Plan
in Appendix F.
6.2.1
In the Reporting Period,
Grave G1 of inspection was undertaken on 2nd, 9th, 16th, 23rdand 30th January 2018. During these inspections,
buffer zone was maintained between the working area and the Grave. The nearby areas were clean, and no
construction materials or mechanical equipment were stored within or close to
the buffer zone.
6.2.2
Since construction works
very close to buffer zone of the Grave G1, cultural heritage mitigation measures and protection measures as provided by the Contractor, therefore has fully
implemented in accordance with EM&A Manual requirements.
7.1.1
According to EM&A
Manual requirements, monitoring of Contractor’s operations during construction
period to report on Contractor’s compliance should be carried out on weekly
basis. Measure to mitigate landscape and
visual impact during construction should be checked and monitored by a
Registered Landscape Architect to ensure compliance with the intended aims of
the mitigation measures. Moreover, the progress
of the engineering works shall be regularly reviewed on site to identify the
earliest practical opportunities for the landscape works to be undertaken.
7.2.1
In the Reporting Period, site inspection for landscape
and visual mitigation measures was undertaken on 5th, 12th, 19th and 26th January 2018 by the Registered Landscape Architect.
7.2.2
Most of the landscape
works such as planting was not yet commenced, but some transplanting works was commenced on 22 May 2017. The detailed inspection checklists were
provided in Appendix K.
8.1.1
During EIA study,
landfill gas hazards are likely to be generated
from the Pillar Point Valley (PPV) Landfill. Hence, regular landfill
gas monitoring is recommended during construction of the proposed toll plaza.
8.1.2
During construction, a
Safety Officer should be appointed to carry out the monitoring works. The
monitoring frequency and areas to be monitored should be set down prior to
commencement of ground-works either by the Safety Officer or an approved and appropriated
qualified person. The routine
monitoring should be carried out in all excavations, manholes, chambers,
relocation of monitoring wells and any other confined spaces that may have been
created. All measurements in
excavations should be made with the extended monitoring tube located not more
than 10 mm from the exposed ground surface. Monitoring should be performed
properly to make sure that the area is free of landfill gas before any man
enters in the area.
8.1.3
For excavations deeper
than 1m, measurements should be carried out:
Ÿ
at the ground surface
before excavation commences;
Ÿ
immediately before any
worker enters the excavation;
Ÿ
at the beginning of each
working day for the entire period the excavation remains open; and
Ÿ
periodically through the working day
whilst workers are in the excavation.
8.1.4
For excavations between
300mm and 1m deep, measurements should be carried out:
Ÿ
directly after the
excavation has been completed; and
Ÿ
periodically whilst the
excavation remains open
8.1.5
For excavations less
than 300mm deep, monitoring may be omitted, at the discretion of the Safety
Officer (SO) or other appropriately qualified person.
8.1.6
To ensure the accuracy
of the monitoring data, zeroing of the gas analyser
shall be undertaken at the start of each day’s monitoring. As advised by the SO, the gas analyser would be optimally calibrated by the self-test
function to provide the most accurate result. The gas analyser
is calibrated and certified by a laboratory accredited under HOKLAS or any other
international accreditation scheme at yearly basis.
8.1.7
The landfill
consultation zone was divided into 6 monitoring zones. The landfill gas
monitoring zones are summarized in Table 8-1 and the layout plan for the monitoring zone is illustrated in
