13.1.1.1
This section further elaborates the requirements of
environmental monitoring and audit (EM&A) for the construction and
operation of the KTE project, based on the
assessment results of various issues. Details
of the EM&A programme are presented as part of this EIA Report in a separate
stand-alone EM&A Manual. The
Environmental Mitigation Implementation Schedule (EMIS) for the recommended
mitigation measures is included in Section
16 of this EIA report.
All EM&A data, assessment and recommendations will be reported in a
series of regular EM&A reports. In
addition, a
dedicated internet web-site will be set up for reporting the EM&A data for
public inspection in real-time.
Real-time reporting in this context refers to the posting of monitoring
data after it has been through the appropriate processing, QA/QC checking by
the ET and validation by the IEC.
13.2.1.1
There are no Declared Monuments within
the project area and there would be no requirements for EM&A under the
EIAO.
13.3.1
Construction Phase
13.3.1.1
The landscape and visual
mitigation measures should be incorporated in the detailed design, so as to
ensure the effectiveness of the mitigation measures. Any changes to the mitigation measures that
may be recommended to match the baseline review result or to match the ongoing
EM&A should also be incorporated in the detailed design.
13.3.1.2
The design, implementation
and maintenance of mitigation measures should be checked regularly to ensure
that they are fully realised and are in compliance with the intended aims of
the measures. Any potential conflicts
among the proposed mitigation measures, the project works, and operational
requirements should also be identified and resolved at an early stage.
13.3.1.3
Landscape proposals and
details of architectural design, chromatic treatment and visual and landscape
mitigation measures for all above ground structures, including station
entrances and ventilation buildings, to demonstrate that they would be sensibly
designed in a manner that responds to the existing urban context.
13.3.1.4
The extent of the agreed
works areas should be regularly checked during the construction phase. Any trespass by the Contractor outside the
limit of the works leading to any damages to existing trees should be reported
to the Independent Environmental Checker, Environmental Team and Engineer’s
Representative.
13.3.1.5
The project construction
team and Environmental Team should also audit the operational measures
recommended in the EIA Study to ensure that they are fully implemented by the
Contractor in accordance with the Project design during the construction phase.
13.3.2
Operational Phase
13.3.2.1
No specific EM&A requirement would be required during the operational phase.
13.4.1.1
With the implementation of the dust suppression
measures stipulated in the Air Pollution Control (Construction Dust)
Regulation, good site practices and proposed mitigation measures, no adverse
dust impact would be expected at the ASRs in the vicinity of the construction
sites. However, dust monitoring requirements are recommended in the
EM&A Manual to ensure the efficiency of the control measures. Details of the EM&A programme are
provided in a stand-alone EM&A Manual.
13.5.1
Construction Phase
13.5.1.1
Construction air-borne noise impacts from the KTE project would be expected at the NSRs identified in
this EIA
Study.
Appropriate mitigation measures would be required in order to alleviate
the impacts to meet the EIAO-TM criteria.
Noise monitoring during construction phase needs to be carried out to
ensure that such mitigation measures would be implemented properly. Noise monitoring should be carried out at the
designated monitoring stations, and measurement should be undertaken at a
minimum logging interval of 30 minutes. Prior
to the commencement of the construction
works of the KTE project, baseline monitoring
should be measured for a continuous period of at least 14 consecutive days at a
minimum logging interval of 30 minutes for daytime. During the impact monitoring, noise
measurement should be conducted at the designated monitoring locations once a
week. Ad hoc noise monitoring should also be carried out if necessary. Details of the EM&A programme are
provided in a stand-alone EM&A Manual.
13.5.2
Operational Phase
13.5.2.1
Prior to the operation of the KTE
project, a noise commissioning
test should be conducted by the Contractor to check for the compliance of the noise
levels from the operation of the fixed plant with the stipulated noise criteria. The testing results should be checked and
signed by the Contractor, the Engineer’s Representative and the Environmental Team
and verified by Independent Environmental Checker respectively.
13.6.1
Construction Phase
13.6.1.1
The predicted ground-borne noise levels would comply
with the stipulated daytime noise criteria and monitoring is, therefore, not required.
13.6.2
Operational Phase
13.6.2.1
Prior to the operational phase of the KTE project, a noise
commissioning test should be conducted to check for the compliance of the
operational ground-borne noise levels with the EIAO-TM noise criteria.
Details of the test requirements, including the selection equipment, commissioning
time and NSRs are provided in a stand-alone EM&A Manual.
13.7.1
Construction Phase
13.7.1.1
The key water quality issues relate to the potential for the release of the silt-laden water from surface works sites, open cut
excavation and tunnelling works. The
water quality assessment concluded that minimisation of water quality
deterioration from land-based construction activities could be achieved through
implementing adequate mitigation measures.
It is recommended that regular site inspections should be undertaken by
the Contractor and audited by the Engineer’s Representative and the
environmental team on the construction activities and works areas in order to
ensure the recommended mitigation measures are properly implemented.
13.7.2
Operational Phase
13.7.2.1
With the
proper implementation of the
recommended mitigation measures,
no adverse water quality impact would
be anticipated during the operational phase of the KTE project. Operational water quality monitoring is, therefore, not required.
13.8.1.1
Waste management will be the Contractor’s
responsibility to ensure that all wastes produced during the construction of
the KTE project are handled, stored and disposed of in
accordance with the recommended good waste management practices and EPD’s
regulations and requirements. The
mitigation measures recommended should form the basis of the site Waste
Management Plan to be developed by the Contractor at the construction stage.
13.8.1.2
It is recommended that the waste arisings, handling
and disposal during construction should be audited regularly by the Engineer’s
Representative Environmental
Team to determine if the wastes are
being managed in accordance with approved procedures and the site Waste
Management Plan. The audit should look
at all aspects of on-site waste management practices including waste
generation, storage, recycling, transport and disposal. Apart from the site inspection, documents
including licences, permits, disposal and recycling records should be reviewed
and audited for compliance with the legislation and contract requirements. In addition, routine site inspections should
check the implementation of the recommended good site practices and waste
management mitigation measures.
13.9.1.1
According to the findings
of the site investigation undertaken for this EIA Study, there would be no land contamination issues in the investigated sites. As such, no remediation
works and specific EM&A requirements for these investigated sites would be
required. However, according to the
endorsed CAP, there is still an area at the existing kerosene store located at
13.10.1.1 Blasting
activities regarding storage and transport of explosives should be supervised
and audited by competent site staff to ensure strict compliance with the
blasting permit conditions.
