13.1.1.1
This section elaborates the requirements of
environmental monitoring and audit (EM&A) for the construction and
operational phases of the Project, based on the assessment results of the
various environmental issues.
13.1.1.2
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 and to identify any further need for
additional mitigation measures or remedial action.
13.1.1.3
The following sections summarise the recommended
EM&A requirements for this Project.
Details of the requirements are provided in a stand-alone EM&A
Manual.
13.4.1.1
With proper implementation of the recommended
pollution control measures, water pollution from the Project would be avoided
and minimised and no adverse water quality impacts would be expected during
construction and operational phases.
Water quality monitoring is therefore not considered necessary. Nonetheless, weekly site audit should be
undertaken during the construction phase to ensure the recommended pollution
control measures are properly implemented.
13.4.1.2
While the Project is expected to improve the
overall water quality of TWN and EM&A for water quality is not considered
necessary for the operational phase under this EIA study, a post-revitalisation
water quality monitoring programme to review compliance with the Water Quality
Goals as stipulated in DSD PN No. 3/2021 will be established and implemented by
the DSD.
13.5.1.1
Waste management would 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 relevant legislation and waste
management guidelines. The recommended
mitigation measures should form the basis of the site Waste Management Plan
(WMP) to be developed by the Contractors as part of the Environmental
Management Plan in accordance with ETWB TC(W) No. 19/2005 Environmental
Management on Construction Sites and submitted to the Architect/Engineer
for approval in the construction phase.
The monitoring and auditing requirement stated in ETWB TCW No.19/2005
should be followed with regard to the management of C&D materials.
13.5.1.2
Monthly site audit should be conducted by the
Environmental Team (ET) during the construction phase to check if wastes are being managed in accordance with
approved procedures. The audit should
cover site inspection on all aspects of on-site waste management practices
including waste generation, storage, recycling, transport and disposal. Apart from site inspections, waste management
related 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
under the site audit.
13.5.1.3
It is expected that limited quantities of waste
would be generated from the operation of the Project and adverse environmental
impacts would not be anticipated with the implementation of good waste management practices following the existing
practices of regular maintenance works.
Hence, no EM&A requirement is considered necessary during the
operational phase.
13.6.1.1
Since no land contamination impact is
anticipated, no EM&A programme is required during the construction or
operational phase.
13.7.1.1
Since no adverse impact on sewerage and sewage
treatment is anticipated, no EM&A programme is required during the
construction or operational phase.
13.8.1.1
A pre-construction ardeid survey should be
conducted no earlier than 3 months before the commencement of construction works
for each section of TWN, for areas within 100m from the Project site
to confirm the location and status of the night roost. Ecological monitoring of ardeid is
recommended to monitor the ardeid usage of the active pre-roosting and roosting
sites (as confirmed by the pre-construction ardeid survey), and of the proposed
temporary floating pontoons. A
plan detailing the monitoring methodology should be submitted to and approved
by AFCD prior to the monitoring. Monthly
counts of species composition and abundance should be undertaken to monitor the
effectiveness of proposed mitigation measures and detect any unpredicted
indirect ecological impacts arising from the proposed Project. The ecological monitoring / surveys should be
undertaken by experience ecologist(s) with relevant working experience. The detail monitoring data should be reported
in the monthly EM&A report. In case of any unforeseen ecological
impacts identified, remedial actions should then be
recommended, where appropriate, in consultation with relevant authorities.
13.8.1.2
Monthly site audit should also be carried out throughout
the construction phase to ensure recommended avoidance / pollution control
measures are properly implemented. In
case of non-compliance, contractor should be informed to strengthen the
proposed measures accordingly. Details
of EM&A requirements are discussed in the separate EM&A Manual. No EM&A programme is required during the
operational phase.
13.9.1.1
Since no unacceptable adverse fisheries impacts
are anticipated during both construction and operational phases, no specific
EM&A programme for fisheries impact is required.
13.10.1.2
A buffer zone of 5 m from Gatehouse of Pok Ngar
Villa (new item pending for grading assessment) should be set up, in which no
construction machineries and construction storage should trespass the buffer
zone. Fencing should also be set up to
clearly demarcate the buffer zone to avoid potential damage due to site
negligence.
13.10.1.3 Monitoring
of vibration, settlement and tilting incorporated with a set of AAA system
shall be employed for Gatehouse of Pok Ngar Villa (new item pending for grading
assessment), Li Cottage (Grade 1), Nos. 1-3 First Street, Tai Wai (Grade 3) and
Entrance Gate, Chik Chuen Wai (Grade 2) during the construction phase. Details of the EM&A requirements for
construction phase are discussed in the standalone EM&A Manual. The actual limiting criteria should be
further agreed with the AMO. A
monitoring proposal, including type of monitoring, distribution of monitoring
points and proposed actions to be taken when reaching respective monitoring
limits, should be submitted to AMO for comments before commencement of the
works. Record of monitoring should be
submitted regularly to AMO during the construction. AMO should be alerted in case any
irregularities are observed.
13.10.1.4 No
EM&A would be required for archaeology during the construction phase.
13.11.1.1
The detailed landscape and engineering design of
the Project would be undertaken so as to ensure compliance with the landscape
and visual mitigation measures described in Section
12.8.
13.11.1.2
A baseline review should be undertaken by the
Contractor at the commencement of the construction contracts to update the
status of landscape resources, character areas and VSRs and submitted to EPD
and PlanD for record. Implementation of
the recommended mitigation measures should be regularly audited during the
construction phase. Details of the
EM&A requirements for construction phase water are discussed in the
standalone EM&A Manual. As the
landscape and visual mitigation measures for operational impacts would be
provided and established during the construction phase, no EM&A programme
is required during the operational phase.
