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 include 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 mitigation measures
·
to verify the environmental impacts predicted in this
EIA
·
to determine project compliance with regulatory
requirements, standards and government policies
·
to take remedial action if unexpected problems or
unacceptable impacts arise
·
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.
Construction Phase
12.2.1 The
construction work will inevitably lead to dust (TSP) emissions, mainly from
excavation, filling activities, truck haulage and material handling. No exceedance of hourly and daily TSP criteria are
predicted at air sensitive receivers (ASRs) in the vicinity of work sites with
four times daily watering on active work areas.
12.2.2 With
implementation of the proposed mitigation measures, dust suppression measures
stipulated in the Air Pollution Control (Construction Dust) Regulation, good
site practices and comprehensive dust monitoring and audit, the dust impact
would be further diminished.
12.2.3 Dust
monitoring is recommended in the EM&A Manual to ensure the efficacy of the
control measures.
Operational Phase
12.2.4
In
view of the project nature, no adverse air quality impact during the operation
phase would be anticipated and therefore monitoring and audit programme is not
required. t
Construction Phase
12.3.1 Construction
noise impacts from this Project, in addition to the concurrent construction
tasks of other Schedule 2 designated projects, CRIII and HKCEC ALE projects,
could be expected at the NSRs identified in this EIA. Appropriate mitigation measures are
required in order to alleviate the impacts to meet the EIAO-TM criteria. Noise
monitoring during construction phase will need to be carried out to ensure that
such mitigation measures are implemented properly.
Operational Phase
12.3.2
In
view of the project nature, no adverse noise quality impact during the
operation phase would be anticipated and therefore monitoring and audit
programme is not required.
Construction
Phase
12.4.1 There
would be potential water quality impacts upon the water sensitive receivers due to
the marine works. Appropriate
mitigation measures are recommended in order
to minimize the potential impacts.
Water quality monitoring and audit during construction phase will need to be carried out
to ensure that such mitigation measures are implemented properly.
Operational Phase
12.4.2 No unacceptable water quality
impacts would be expected from the Project. No monitoring programme specific for
operational water quality would be required.
12.5.1 Waste
management will be 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 EPD’s regulations and requirements.
The mitigation measures recommended in Section 6 should form the basis
of the site Waste Management Plan to be developed by the Contractor at the
construction stage.
12.5.2 It is
recommended that the waste arisings generated during the construction
activities should be audited periodically to determine if wastes are being
managed in accordance with approved procedures and the site Waste Management
Plan. The audits should look at all
aspects of waste management including waste generation, storage, transport and
disposal. An appropriate audit
programme would be to undertake a first audit near the commencement of the
construction works, and then to audit on a quarterly basis thereafter. In addition, the routine site
inspections should check the implementation of the recommended good site
practices and other waste management mitigation measures.
12.7.1
As
all the 19 coral colonies found in recent surveys were identified as feasible
for transplantation, it is recommended to translocate
all these coral colonies at
coastlines within ex-PCWA Basin and along seawall at North Point to the nearby suitable habitats such as Junk Bay where healthy
coral communities of the same species were recorded. A detailed translocation
methodology (including baseline survey and monitoring of transplanted corals)
should be drafted during the detailed design stage of the Project. The detailed
methodology, monitoring proposal and ecologist involved in coral translocation
should be approved by AFCD prior to commencement of this translocation
exercises.
12.7.2 It is recommended to implement monitoring of the transplanted corals
after translocation. The health status of each transplanted coral
colony should be carefully recorded.
For hard corals, this should include information on surface area with
partial mortality and blanched / bleached area. For gorgonian coral, the
percentage of branches affected by partial mortality and secretion of mucus
should be recorded. Details of monitoring requirements are presented in the
EM&A manual.
Introduction
12.8.1 The EIA has recommended landscape
and visual mitigation measures to be undertaken during construction and
operation phases of the Project. This Section defines the EM&A requirements
to ensure the proposed landscape and visual impact mitigation measures are
effectively implemented.
12.8.2
The construction phase EM&A of the landscape and visual environment
and mitigation works shall be carried out as part of the site audit programme.
Specific EM&A during operation phase of the Project is not required as long
as the proposed mitigation measures in the EIA and as depicted in the Landscape
Mitigation Plan are fully implemented.
Baseline Monitoring
12.8.3
Baseline changes with respect to the landscape and visual environments
should be carried out in reference to the recorded baseline conditions of the
site as described in Section 10 of the EIA. The monitoring should in particular
record changes of each landscape resource, landscape character area and the
view conditions of each visually sensitive receiver. Parameters used to
describe changes in each of the above should be the same as in Section 10 of the
EIA.
12.8.4
The baseline monitoring should be conducted as a one-off site survey
prior to commencement of any construction works.
Construction Phase
12.8.5
The proposed landscape and visual mitigation measures for the
construction phase are described in Sections 10 and 13. The measures are on-site management
measures to be undertaken by the Contractor. All mitigation measures proposed in the
EIA and implemented by the Contractor should be audited by a landscape auditor,
as a member of the Environmental Team, on a regular basis to ensure compliance
with the intended aims of the measures. Site inspection should be undertaken at
least once every two weeks throughout the construction period.
12.8.6
In particular, 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, including any damage to the existing trees, woodland and
vegetation should be noted.
12.8.7
The landscape auditor should also audit the proposed operation phase mitigation
measures in the EIA and as depicted in the Landscape Mitigation Plan to ensure
that they are fully implemented within the Project design and construction.
Operation
Phase
12.8.8
The proposed landscape and visual mitigation measures for the operation
phase are described in Sections 10 and 13.
The measures are design measures to be incorporated in the detailed
planning and design of the reclamation, infrastructure and open spaces works. Landscape mitigation measures would be
subsequently managed and maintained according to ETWB TCW 2/2004, subject to
the possible amendment if CEDD has identified another implementation,
management and maintenance agent for the waterfront open spaces.
12.8.9
Monitoring of design works against the recommendations of the landscape
and visual impact assessment should be undertaken during the detailed design to
ensure that the mitigation measures are satisfactorily incorporated into the
design. Any changes to the design,
include design changes on site should also be checked.
12.9
Cultural Heritage
12.9.1 There is no monitoring and audit
requirement for the marine archaeology.
