Environmental Monitoring and Audit REQUIREMENTS
11.1.1
This Section summarises the requirements for
environmental monitoring and audit (EM&A) during the construction and
operation phase of the Project and associated works based on the various
assessment results presented in this EIA Report. Details of the EM&A
requirements are given in a stand-alone EM&A Manual.
11.1.2
To ascertain that the recommendations in the EIA study
are followed and that the mitigation measures implemented are effective, it is
considered necessary to develop EM&A procedures and mechanisms such that
the implementation of the mitigation measures can be tracked and their
effectiveness assessed. The following sections outline the recommended
EM&A requirements with the Implementation Schedule presented in Appendix 11.1.
Construction
Phase
11.2.1
The EIA study concluded that no adverse fugitive dust
impact is anticipated during the construction of the Project. Continuous
dust monitoring should be carried out so as to ensure that relevant legal
requirements and standards are complied with during the construction phase of
the Project.
11.2.2
It is recommended to conduct regular site inspections,
i.e. on weekly basis, throughout the construction phase of the Project so as to
confirm proper implementation of the dust control measures and good site
practices as recommended in Section 3.9.
11.2.3
EM&A requirements related to air quality during the
construction phase are summarised in the Implementation Schedule provided in Appendix 11.1.
Operation Phase
11.2.4
The EIA study concluded that no adverse air quality
impact is anticipated during the operation of the Project. EM&A
related to air quality during the operation phase is considered not
necessary.
Construction
Phase
11.3.1
The EIA study concluded that no adverse noise impact is
anticipated during the construction of the Project. It is recommended to
prepare a construction noise management plan during the design / tendering and
implementation stage of the construction works, with an aim to verify the
inventory of noise sources, update the construction noise impact assessment if
necessary, assess the effectiveness and practicality of all identified measures
and update the proposed noise mitigation measures as necessary.
11.3.2
Regular noise monitoring should be carried out so as to
ensure that relevant legal requirements and standards are complied with during
the construction phase of the Project.
11.3.3
It is recommended to conduct regular site inspections,
i.e. on weekly basis, throughout the construction phase of the Project so as to
confirm all recommended noise mitigation measures and good site practices as
recommended in Section 4.8 are in place.
11.3.4
EM&A requirements related to noise during the
construction phase are summarised in the Implementation Schedule provided in Appendix 11.1.
Operation Phase
11.3.5
The EIA study concluded that no adverse noise impact is
anticipated during the operation of the Project with the implementation of the
proposed mitigation measures. To verify the effectiveness of the proposed
noise mitigation measures, road traffic noise levels should be monitored at
representative NSRs during the first year after the completion of road works.
11.4
Water Quality Impact
Construction
Phase
11.4.1
Adverse water quality impact arising from the
construction works of the Project is not anticipated with the recommended
mitigation measures in place. Regular site inspections, i.e. on weekly
basis, should be conducted during the construction phase to ensure the proper
implementation of the recommended mitigation measures in Section 5.7.
11.4.2
EM&A requirements related to water quality during
the construction phase are summarised in the Implementation Schedule provided
in Appendix
11.1.
Operation Phase
11.4.3
The EIA study concluded that there would be no adverse
water quality impact arising from the operation of the Project. EM&A
related to water quality during the operation phase is considered not
necessary.
11.5
Waste Management Implications
Construction
Phase
11.5.1
The EIA study concluded that no adverse environmental
impact or other hazards arising from waste management is anticipated during the
construction of the Project with the implementation of good site
practices. It is recommended that regular site inspections, i.e. on a
weekly basis, are conducted during the construction phase to audit the waste
management practices and to determine if wastes are being managed in accordance
with the recommended good site practices and WMP. The site inspections
will investigate all aspects of waste management including waste generation,
storage, handling, recycling, transportation and disposal.
11.5.2
EM&A requirements related to waste management
during the construction phase are summarised in the Implementation Schedule
provided in Appendix
11.1.
Operation Phase
11.5.3
There is no waste management issue as no waste is
expected to be generated during the operation phase of the Project.
EM&A related to waste management during the operation phase is considered
not necessary.
11.6.1
The EIA concluded that no land contamination impacts
are anticipated for the Project. EM&A related to land contamination is
considered not necessary during the construction and operation phases of the
Project.
Construction
Phase
11.7.1
Regular monitoring will be conducted within 100m of the North District Park Egretry and Day Roost (NDPEDR) at a frequency of at least monthly or more frequent
during construction phase. Regular monitoring aims to monitor the ardeid
day roosting and breeding activities, criteria to be monitored include the
status, location and extent of NDPEDR, the condition of trees used as breeding
and roosting activities, the species, abundance and the returning time of the
breeding and roosting ardeids, as well as their flight height and flight line.
11.7.2
Good site practices are also required during the construction
phase to minimise the potential indirect impact. Regular audits and site
inspections should be carried out to ensure that the mitigation measures
recommended in this EIA Report and EM&A Manual (e.g. strictly using non-percussive piling method
within the 100m area of NDPEDR for all year round, using Quality Powered
Mechanical Equipment (QPME), low-noise surfacing materials and movable noise
barriers and mitigation for reducing night-time light glare from reaching the
NDPEDR) are properly implemented by the Contractor such
that there would be no unacceptable ecological impact on the conservation
important species / sites
(e.g. NDPEDR) due to noise, dust, site run-off, and
other pollutions from the construction sites.
11.7.3
Specific details on the monitoring of the NDPEDR and
the EM&A programme are provided in the stand-alone EM&A Manual.
Operation Phase
11.7.4
The regular monitoring mentioned in Section
11.7.1 shall also be carried out at the first breeding season (March to
August) after operation. If the commencement of operation is in the
middle of a breeding season, the operational phase monitoring will cover that
breeding season and the next breeding season. Specific
details on the monitoring and the EM&A programme are provided in the
stand-alone EM&A Manual.
11.8
Landscape and Visual Impact
Construction
Phase
11.8.1
The EIA Report has recommended landscape and visual
mitigation measures for the construction and operation phases of the Project.
11.8.2
The mitigation measures listed in Table 9.11
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.
Operation Phase
11.8.3
The operation phase mitigation measures listed in Table
9.12 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.
Construction
Phase
Archaeology
11.9.1
As a precautionary measure, the project proponent and
his/her contractor are required to inform AMO immediately when any antiquities
or supposed antiquities under the Antiquities and Monuments Ordinance (CAP.53)
are discovered during the course of works.
Built Heritage
11.9.2
No direct and indirect impacts from construction
vibration to the mentioned graded historic buildings listed in Table 10.1
and no grading built heritage items BH-02, BH-03 and BH-04 listed in Table
10.2 are anticipated due to considerable separation distance (over 110m)
from the works boundary of the Project. However, It is
recommended to monitor any vibration and building movement induced by the
proposed works on the graded historic buildings (No.5 Ng Uk Tsuen, GB-03),
which is closest to the boundary of the Works Area, as well as on the Grade 1
historic building (Pang Ancestral Hall, GB-01). This will ensure that there are
no negative impacts from vibration on the graded historic buildings. For BH-01, although it is located relatively closer (about 20m) to
the boundary of the Works Area, potential direct and vibration impacts are not
anticipated as the closest major underground construction works like piling and
piling cap construction are located around 300m away. No EM&A is
required.
Operation Phase
11.9.3 Adverse
archaeological or built heritage impacts are not anticipated during the
operation of the Project. EM&A related to cultural heritage
during the operation phase is considered not necessary.
