Environmental Monitoring and Audit
11.1.2 The
following sections summarize the recommended EM&A requirements with the
Project Implementation Schedule presented in Appendix 11.1. Details of the EM&A programme and
the specific monitoring requirements are presented in a stand-alone EM&A
Manual.
Construction Phase
11.2.1
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 work fronts. Regular hourly dust monitoring
requirements are recommended in the EM&A Manual to ensure the efficacy of
the control measures. Details of
the EM&A programme are provided in a stand-alone EM&A Manual.
Operation Phase
11.2.2 No
adverse air quality impacts associated with the operation of the Project are
expected, and thus no monitoring and audit programme would be required.
Construction Phase
11.3.1 Construction
noise impacts at the representative NSRs from the Project have been assessed in
this EIA Report. Appropriate
mitigation measures are recommended to alleviate the impacts to meet the
EIAO-TM criteria. Noise monitoring
during construction phase would be implemented to check the noise compliance
with TM-EIAO criteria and the effectiveness of mitigation measures. Details of the EM&A programme are
provided in a stand-alone EM&A Manual.
Operation Phase
11.3.2 Prior
to the operation of the respective staging of SHD Replanning Works and
population intake of SHD Topside Development, noise commissioning tests should
be conducted to check the compliance of the planned fixed plant noise source
and railway noise. Details of the commissioning
tests and monitoring programme are provided in a stand-alone EM&A Manual.
Construction
Phase
11.4.1
With the implementation of the recommended water
quality mitigation measures, no adverse water quality impact would be expected
at the WSRs located in the vicinity of the work fronts. Regular site inspections should be
undertaken to inspect the construction activities and works areas in order to
ensure the recommended mitigation measures are properly implemented.
Operation
Phase
11.4.2
No adverse water quality impacts associated with
the operation of the Project are expected, and thus no monitoring and audit
programme would be required.
11.5.1 With
the implementation of the recommended precautionary measures to cater
for the emergency situations, emergency discharge from the planned SPS is
not expected and thus no adverse impact on water quality due to the emergency
discharge is anticipated.
11.5.2 With
the mitigation measures recommended in the EIA implemented, specific auditing
during the operation phase of the Project is not required.
Construction Phase
11.6.1 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 the recommended good waste management practices and relevant
legislation and waste management guidelines. Routine site inspections and auditing
would be conducted to check the implementation of the recommended good site
practices and other waste management mitigation measures.
11.6.2 A
Waste Management Plan (WMP) should be prepared in accordance with ADV-19 and
submitted to the Engineer for approval.
The recommended mitigation measures in this EIA Report should form the
basis of the WMP.
Operation Phase
11.6.3 It
is expected that there would be limited quantities of waste to be generated
from the operation of the Project and no adverse environmental impacts is
anticipated with the implementation of good waste management practices. Monitoring and audit programme for the
operation phase of the Project would not be required.
11.7.1 Based
on the site appraisal results, 9 facilities / areas (i.e. AB2, AB3, AB6, AB8, AB9,
Transformers located outside AB11, AB16, AB22 and MDB) within existing SHD have
been identified as potentially contaminated and require further site
investigation. However, the
concerned areas are still in operation and undertaking the site investigation
(SI) works at this stage is not feasible due to significant impact to the
existing SHD operations, SI works are therefore recommended to carry out after
decommissioning of the concerned area(s). If necessary, any soil / groundwater
contamination would be identified and properly treated according to the
approved Remediation Action Plan(s) (RAP).
Remediation Report(s) (RRs) demonstrating the completion of remediation
works at the area(s) (if any) confirmed with contamination will be prepared and
submitted to EPD for approval prior to the commencement of construction works
at the contaminated areas.
11.7.2 With
the implementation of the recommended follow-up works for the concerned areas,
any soil / groundwater contamination would be identified and properly treated
prior to construction works at the concerned areas. Specific EM&A requirement is
therefore not required.
11.8
Landscape and Visual
Construction Phase
Operation Phase
11.8.2 As the operation landscape and
visual mitigation measures would be provided during the construction phase,
therefore no specific EM&A requirement is required during operation phase.
11.9.1 No
adverse hazard to life impact is expected during the construction and operation
of the Project, and thus no monitoring programme would be required.
