ENVIRONMENTAL
mONITORING AND AUDIT
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 Negligible dust impact is expected from DP6 as dredging is a marine-based
activity. As there is only one
dredger to be operated for DP6, insignificant additional marine traffic
emission would be anticipated.
Adverse odour impact from dredging
activities is not expected as the dredging area is not seem to have highly
contaminated sediment.
12.2.2 Negligible dust impact, marine emission and odour
impact from the DP6 would be expected, air quality
monitoring and audit is therefore not required.
Operational Phase
12.2.3
There will be no exceedance of AQOs at the sensitive
receivers. No mitigation measures or environmental
monitoring are considered necessary during the operation phase of the Project
Construction Phase
12.3.1 The proposed cross harbour water
mains will extend from Wan Chai near the HKCEC Extension to connect to the
existing system near the
Operational Phase
12.3.1
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.
12.6.1 As no
adverse land contamination impacts were identified for the Project, EM&A works
for land contamination were considered not necessary.
12.7.1 No
monitoring programme specific for marine ecology would be required.
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
During operation, there will be
no impacts as the cross-harbour water mains will be underneath the
harbour. No monitoring programme specific for
operational phase would be required.
12.9.1
There
is no monitoring and audit requirement for the marine archaeology.
