Environmental Monitoring
and Audit Requirements
12.1.1.1
This section provides a summary
of the requirements of environmental monitoring and audit (EM&A) for the
construction and operation phases of the Project and associated works based on
the assessment results of the various environmental issues. Details of the EM&A
requirements are provided in a stand-alone EM&A Manual.
12.1.1.2
The purpose of the EM&A
programme is to ascertain and verify the assumptions implicit to, and accuracy
of, EIA study predictions. The EM&A programme includes the scope of the
EM&A requirements for the Project to ensure compliance with the EIA study recommendations,
to assess the effectiveness of the recommended mitigation measures. The
following sections summarise the recommended EM&A requirements with the Implementation
Schedule of Recommended Mitigation Measures presented in Appendix 12.1.
12.2.1.1
EM&A for potential dust
impacts should be conducted during construction phase so as
to check compliance with the legislative requirements. Details of the monitoring and audit programme
are contained in a stand-alone EM&A Manual.
12.2.1.2
Regular site audits for
potential dust impact are recommended to be conducted during the entire
construction phase of the Project so as to ensure the
dust mitigation measures and the dust suppression measures stipulated in Air
Pollution Control (Construction Dust) Regulation are implemented in order.
12.2.2
Operation
Phase
12.2.2.1
No unacceptable adverse impact
arising from the Project is anticipated during the operation phase of the
Project. Therefore, the EM&A works
for the operation phase are considered unnecessary.
12.3.1.1
An EM&A programme is
recommended to be established according to the expected occurrence of noisy
activities. All the recommended mitigation measures for daytime normal working
activities should be incorporated into the EM&A programme for
implementation during construction. Details of the EM&A requirements are
provided in the EM&A Manual.
12.3.2.1
Road
traffic noise levels should be monitored at representative NSRs which are in
the vicinity of the recommended direct mitigation measures, during the first
year after road opening. The purpose of the monitoring is to ascertain that the
recommended mitigation measures are effective in reducing the noise levels.
12.4
Water Quality Impact
12.4.1.1
Regular site inspection during
the construction phase is proposed to inspect the construction activities and
works area to ensure the recommended mitigation measures are properly
implemented.
12.4.2
Operation
Phase
12.4.2.1
No adverse water quality
impacts would be expected from the operation road works if the recommended
mitigation measures are implemented properly.
No water quality monitoring is therefore considered necessary.
12.5
Waste Management Implications
12.5.1
Construction
Phase
12.5.1.1
It will be the Contractor’s
responsibility to ensure that any wastes produced during the construction works
are handled, stored and disposed of in accordance with
recommended good waste management practices and relevant regulations and other
legislative requirements. The recommended mitigation measures detailed in Section 6.7 should form the basis of the site Waste Management Plan (WMP) to be
developed by the Contractor in the construction stage.
12.5.1.2
It is recommended that the
waste arisings generated during the construction activities should be audited
regularly by the Environmental Team (ET) to determine if wastes are being
managed in accordance with approved procedures. The audits should look at all
aspects of on-site waste management practices including waste generation,
storage, recycling, transport and disposal. Apart from
site inspections documents including licenses, permits disposal and recycling
records should be reviewed and audited for compliance with the legislation of
the recommended good site practice and other waste management mitigation
measures.
12.5.2
Operation
Phase
12.5.2.1
Adverse environmental impacts associated with handling, storage and
disposal of waste are not expected from the operation of the Project with the
implementation of good waste management practices. Therefore, waste monitoring
and audit programme for the operation phase of the Project would not be
required.
12.6.1.1
Since no land contamination
impacts are anticipated for the Project, no EM&A programme is required
during the construction or operation phase.
12.7.1
Construction
Phase
12.7.1.1
Safety requirements stated in Chapter 8 of the Landfill Gas Hazard
Assessment Guidance Note should be implemented properly during construction
phase within the 250m consultation zone.
12.7.2
Operation Phase
12.7.2.1
For maintenance of Tsuen Wan
Road, resurfacing or other maintenance works will be carried out at open space
and any risk from LFG are unlikely. However, if entry into manholes or chambers
are undertaken, works in confined spaces under the Factories and Industrial
Undertakings (Confined Spaces) Regulation of the Factories and Industrial
Undertakings Ordinance should be observed and the Code
of Practice for Safety and Health at Work in Confined Space should be followed
to ensure compliance with the Regulation. Monitoring requirement and precaution
measures will be formulated in risk assessment report by competent person under
the Factories and Industrial Undertakings (Confined Spaces) Regulation.
12.7.2.2
In addition, if any construction is required for the maintenance work
during operational stage, the responsible party should follow the monitoring
works as recommended above for construction phase.
12.8.1
Construction Phase
12.8.1.1
No impacts would be anticipated to any built heritage
identified. Thus, no mitigation measure
would be required.
12.8.1.2
No Site of Archaeological
Interest (SAI) is identified within assessment area. No archaeological impact
would be anticipated. Thus, no mitigation measure would be required. As a precautionary measure, AMO should be
informed immediately in case of discovery of antiquities or supposed
antiquities in the course of works, so that appropriate mitigation measures, if
needed, can be timely formulated and implemented in agreement with AMO.
12.8.2
Operation Phase
12.8.2.1
No impact to cultural heritage would
be anticipated from the operation of the Project. Hence, no mitigation measure would be required
for the operation phase.
12.9.1
Construction
Phase
12.9.1.1
The mitigation measures listed
in Table 11.9 shall be adopted during the construction phase. It is recommended
that regular site inspections during the construction phase should be
undertaken to inspect the construction activities and works areas in order to ensure the recommended mitigation measures are
properly implemented.
12.9.2
Operation
Phase
12.9.2.1
The operation phase mitigation measures listed in Table 11.10 shall be adopted during the detailed design and be built as part of
the construction works at the last stage of the construction period so that
they are in place at the date of commissioning of the Project. However, it
should be noted that the full effect of the soft landscape mitigation measures
would not be appreciated for several years.
