3.5.2
Should non-compliance of the environmental
quality criteria occurs, remedial actions will be triggered according to the
Event and Action Plan which presented in Appendix F.
Noise
3.6.1
The TM-CLKL EIA study
concluded that no existing noise sensitive receiver (NSR) was identified within
the Study Area at Tuen Mun.
Therefore, no planned NSR designated at the Project sites of Tuen Mun. Based upon this, no noise monitoring is
necessary for construction phase under the Contract.
3.6.2
Regular site inspections
and audits will be carried out during the construction phase in order to
confirm compliance with the regulatory requirements and conformity of the
Contractor with regard to noise control and contract conditions.
Water Quality
3.6.3
No marine works will be
undertaken under the Contract.
Based upon this, no water quality monitoring is necessary for
construction phase.
Ecology
3.6.4
Since the Works of the Contract
would not generate marine ecological impact, no dolphin monitoring under
the Contract was conducted.
3.6.5
During construction phase, the ET will
perform Pitcher Plants inspection at least once every week to report the growth
condition (only undertaken at Establish
period) and protection measures.
Landscape and Visual
3.6.6
According to EIA recommendation,
site inspection and audit
shall be required to be undertaken in the operation stage. Measures
to mitigate landscape
and visual impacts during construction should be checked and monitored by a
Registered Landscape Architect to ensure compliance with the intended aims of
the mitigation measures in accordance with the EM&A
Manual.
Cultural Heritage
3.6.7
Grave G1 of heritage resources is situated near the proposed
toll plaza in Tuen Mun. Site inspections should be
undertaken at least once per week throughout the construction period to ensure
compliance with the intended aims of recommended mitigation measures.
Monitoring and
Measurement of Landfill Gas
3.6.8
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. Safety Officer or an approved and
appropriated qualified person should be carried out the monitoring works to
make sure the area free of landfill gas before any man enters in the area.
3.6.9
Depending on the results of the measurements, actions
required will vary and should be set down by the Safety Officer or other appropriately
qualified person. As a minimum these should encompass those actions specified
as follow:

4.4.1
Investigation for the 1-hour and 24-hour TSP exceedance was undertaken upon received the monitoring results by the ET.
4.4.2
For the exceednances in the reporting period,
the investigation reports were submitted to all relevant parties and concluded
that those exceedances are unlikely related to the Contract work and no
corrective action was required accordingly. The detailed investigation reports and findings can
be referred to the Monthly EM&A
Reports of the contract.
5.1.1
According to the EM&A Manual
requirements, regularly inspection for Pitcher Plants at least once every week to report it growth and protection
measure situation shall be conducted
during construction period.
5.1.2
Total 181 pitcher plants
were transplanted to final receptor site and the rest of the Pitcher Plant
individuals (certified dead by the specialist) were not transplanted and were
treated as general refuse. All the transplantation of pitcher plant from the
nursery site to final receptor site was completed on 10th September
2015.
5.2.1
A total 53 occasions of inspection were carried out by the Contractor and ET during
the Reporting Period.
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 establish 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 prevention of any possible damage to the grave and to ensure
that proposed mitigation measures are implemented. The broad scope of the audit
will involve supervision of the following:
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
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:
The extent of the agreed
works areas should be regularly checked during the construction phase to ensure
the buffer is being maintained; and
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 this Reporting Period, there are total 53 occasions to carry out the Grave G1 inspection. During site inspection, buffer zone was observed
between the working area and the Grave and no construction
material or equipment was stored nearby the Grave.
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 this Reporting Period, Registered Landscape
Architect with the Contractor had undertaken a total of 52 occasions of inspection.
7.2.2
During the Reporting
Period, most of the landscape works such as planting was not yet commenced, but some transplanting works was commenced on 22 May 2017. Existing trees
on boundary of the project area were properly protected and no damage of the
existing trees were record in this Reporting Period.
Felled trees during construction were collected by a licensed collector for
recycling. The detailed inspection checklists can
be referred to
relevant Monthly EM&A Reports of the Contract.
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:
at the ground surface
before excavation commences;
immediately before any
worker enters the excavation;
at the beginning of each
working day for the entire period the excavation remains open; and
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:
directly after the
excavation has been completed; and
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 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 part of the QA/QC, calibration of the
gas analyser shall be conducted at least once every
two weeks according to the specification of the manufacturer¡¦s operation
manual.
8.1.7
