12.1.1
This section further elaborates the requirements of EM&A for the
construction and operation of the Project based on the assessment results of
various environmental issues.
12.1.2
The objectives of carrying out EM&A for the Project including the
following:
·
to provide a database against which any
short or long term environmental impacts of the Project can be determined;
·
to provide an early indication should any
of the environmental control measures or practices fail to achieve the
acceptable standards;
·
to monitor the performance of the Project
and the effectiveness of the mitigation measures;
·
to verify the environmental impacts
predicted in this EIA study;
·
to determine project compliance with
regulatory, standards and government policies;
·
to take remedial action if unexpected
problems or unacceptable impacts arise; and
·
to provide data to enable an
environmental audit.
12.1.3
The following sections summarise the recommended EM&A requirements.
Details of EM&A are provided in a stand-alone EM&A Manual.
12.2.1
Recommended noise mitigation measures and their detailed implementation
schedules, environmental monitoring and audit measures are recommended during
the construction phase of the Project. Schedule and extent of the monitoring
programme is presented in the stand-alone EM&A Manual. A proactive EM&A
programme is necessary to be provided by the contractor, in order to ensure
that construction noise impact to the NSRs should be minimized as far as
practicable. An appropriate path for noise complaints handling procedures is a
key element of the EM&A programme.
Detailed implementation schedules of all mitigation measures are also
provided in the EM&A Manual.
12.2.2
Road traffic noise monitoring is recommended at representative NSRs
during the first year of the road opening.
12.2.3
Recommended noise mitigation measures and their detailed implementation
schedules, as well as monitoring procedures and locations are presented in the
EM&A Manual. Traffic noise impacts and effectiveness of the noise
mitigation measures could be evaluated through the monitoring exercise.
12.3.1
With the implementation of the proposed dust suppression measures, good
site practices and dust monitoring and audit programme, no adverse dust impact
would be expected at the ASRs. Details
of the monitoring requirements such as monitoring locations, frequency of
baseline and impact monitoring are presented in the EM&A manual separate
for this report.
12.4.1
For protection of the water quality during construction of the road
widening works, the following environmental monitoring and management measures
should be incorporated into the Environmental Protection and Pollution Control
Requirements in the Contractor’s specification, as a minimum:
a)
discharges should be monitored to ensure
that they comply with the TM on Effluent Standards and any applicable discharge
licenses; and
b)
effluent containing cement-generated
material should be checked periodically with respect to pH.
12.5.1
To ensure the safety of the Contractor’s personnel,
landfill gas monitoring for methane, carbon dioxide and oxygen shall be carried
out to identify any migration between the landfill and the site.
12.5.2
Monitoring shall be carried out and reported in a
similar manner to that for the Restoration Contract to provide comparable
data. The presentation format
for landfill gas monitoring shall be based on this format provided in Appendix
C3 in of the EM&A Manual and agreed with EPD.
12.6.1
It is the Contractor’s responsibility to ensure that all wastes
produced during the construction of the Project are handled, stored, and
disposed of in accordance with good waste management practices and relevant
regulations and requirements. The mitigation measures recommended in Section
6.6 should form a basis of the Waste Management Plan (WMP) to be developed
by the Contractor in the construction phase of the Project.
12.7.1
The risk to the road and workforce population of
Tsuen Wan Road is dominated by an earthquake event affecting the YKTWTW and the Tsuen Wan Road and subsequent chlorine
release at YKTWTW. The risk is relatively low due to its
significant distance to YKTWTW where no mitigation measure that could
significantly reduce such risk is considered cost-effective or
practicable. Nevertheless, several
measures are recommended in ClausesSections 9.8.29 to
9.8.30 and Section 9.2 in
theis EIA Report and
the EM&A Manual, respectively.
12.8.1 It is recommended that an EM&A Manual and Implementation Schedule be prepared for the Project. This would include, inter alia, recommendations on tree protection measures during construction, a short term plant establishment plan and a long term Landscape Management Plan. A programme of site inspections, both during construction and operation will be identified.
12.9.1
No specific environmental monitoring or audit provisions are required
with respect to ecological impacts.
12.10.1
No specific environmental monitoring or audit provisions are required
with respect to cultural heritage impacts.
