Stations) were adopted for impact water quality monitoring effective since 8
September 2017. For details and status of the proposed changes, please refer to
section 6.4.9.
4.2.5 Due
topographical condition of the original location of SR3, alternative water
quality monitoring station, naming as SR3(N) which is situated in vicinity of
the original water quality monitoring stations (SR3) was justified and verified
by the ET Leader of Contract No. HY/2013/01 on 8 November 2017 and IEC/ENPO on
13 November 2017 respectively. Alternative water quality monitoring stations
SR3(N) was approved by the authority and adopted on 22 December 2017.
4.2.6 Same

6.4.1 In
response to the site audit findings, the Contractors carried out corrective
actions.
6.4.2 A
summary of the Implementation Schedule of Environmental Mitigation Measures
(EMIS) is presented in Appendix B. Most of the necessary mitigation measures
were implemented properly.
6.4.3
There were minimal vessel movement after major works has been
substantially completed under this Contract and training of marine travel route
for marine vessels operator was given to relevant staff and relevant records
were kept properly, as necessary. Nevertheless, the Contractor is reminded
strictly follows the approved Regular Marine Travel Routes plan.
6.4.4
Regarding the implementation of dolphin monitoring and protection
measures (i.e. implementation of Dolphin Watching Plan, Dolphin Exclusion Zone
and Silt Curtain integrity Check), regular checking were conducted by the
experienced MMOs within the works area to ensure no dolphin was trapped by the
enclosed silt curtain systems. Any dolphin spotted within the enclosed silt
curtain systems was reported and recorded. Relevant procedures were followed
and measures were well implemented. Silt curtain systems were also inspected
timely in accordance to the submitted plan. All inspection records were kept
properly.
6.4.5 Acoustic
decoupling measures on noisy plants on construction vessels were checked
regularly and the Contractor was reminded to ensure provision of ongoing
maintenance to noisy plants and to carry out improvement work once insufficient
acoustic decoupling measures were found.
6.4.6 Frequency
of watering per day on exposed soil was checked; with reference to the record
provided by the Contract, watering was conducted at least 8 times per day on
reclaimed land. The frequency of watering is the mainly refer to water truck.
Sprinklers are only served to strengthen dust control measure for busy traffic
at the entrance of Portion D. As informed by the Contractor, during the
mal-function period of sprinkler, water truck will enhance watering at such
area. The Contractor was reminded to ensure provision of watering of at least 8
times per day on all exposed soil within the Contract site and associated works
areas throughout the construction phase.
6.4.7 After
review, no floating grout production was in operation at any time in April
2018 for Contract No.HY/2010/02. Condition 3.26A of EP-353/2009/K for Contract
No.HY/2010/02 is complied with during the reporting month.
6.4.8
Due to the commencement of marine work of the Expansion of Hong Kong
International Airport into a Three-Runway System (3RS Project), a large
portion of works site boundary will be established at the northern part
of the existing airport Island. The recent arrangement of works boundary of 3RS
Project which delineates the boundary of the designated 3RS Project (for the
indicative 3RS boundary, please refer to Figure 5). The works area of 3RS
project will affect several water quality monitoring stations and the dolphin
monitoring transect lines which are being used for conducting
monitoring under Contract No. HY/2010/02. The EM&A Programme for the HZMB
HKBCF Project will therefore be affected. As a result, a proposal was prepared
by ET in accordance with condition 5.1 of EP-353/2009/K and condition 4.1 of
EP-354/2009/D, to relocate water quality monitoring stations from SR5, IS10,
CS(Mf)3 and alternate the transect lines of dolphin monitoring 2, 3, 4, 5, 6
and 7. A revised proposal has been updated and sent to IEC/ENPO for their
further review on 24 March 2017 and IEC/ENPO verified the revised proposal on
the same date. The revised proposal has been sent to authority by project team for
review and approval on 3 April 2017. The authority subsequently approved the
proposal on 12 May 2017.
6.4.9
Due to substantial completion of marine works by the end of June 2017, it
is anticipated that the remaining construction works under Contract No.
HY/2010/02, which include ground investigation (GI) works, construction of
temporary timber platform, removal of jetty and reinstatement of seawall at the
western section, construction of outfall at the eastern seawall, would cause
limited disturbance to water column and not to the seabed. In view of this, a
proposal for change of EM&A programme/requirements was prepared by ET in
accordance with Condition 5.1 of EP-353/2009/K and Condition 4.1 of EP-354/2009/D,
to terminate water quality monitoring works at stations IS5, IS(Mf)6, IS8,
SR4(N), SR5(N), SR6, SR10A, SR10B(N), CS4, CSA and CS6, and dolphin monitoring
(line-transect vessel survey method) covering NEL and NWL when perimeter silt
curtain under the Contract is completely removed and vessel traffic numbers
average 10 per month for Contract No. HY/2010/02. A revised proposal has been
updated and sent to IEC/ENPO for their further review on 15 August 2017 and
IEC/ENPO verified the revised proposal on 16 August 2017. The revised proposal
has been sent to authority by project team for review and approval on 21 August
2017. The authority subsequently approved the proposal on 7 September 2017.
6.4.10 The
monthly EM&A programme was undertaken in accordance with the Updated
EM&A Manual for HKBCF (Version 1.0). It should be noted that the air
quality, noise, water quality and dolphin monitoring works for the Contract are
covered by Contract No. HY/2013/01 Hong Kong-Zhuhai-Macao Bridge HKBCF –
Passenger Clearance Building effective since 1 September 2017. The ET of the
Contract is required to conduct EM&A monitoring as part of EM&A
programme if these monitoring stations are no longer covered under Contract No.
HY/2013/01.
6.4.11 Due
topographical condition of the original location of SR3, alternative water
quality monitoring station, naming as SR3(N) which is situated in vicinity of
the original water quality monitoring stations (SR3) was justified and verified
by the ET Leader of Contract No. HY/2013/01 on 8 November 2017 and IEC/ENPO on
13 November 2017 respectively. Alternative water quality monitoring stations
SR3(N) was approved by the authority and adopted on 22 December 2017.
6.4.12 Due
to permission to carry out AQM at Hong Kong SkyCity Marriott Hotel could not be
granted after the end of January 2018, alternative air quality monitoring
station naming as AMS7B was justified and verified by the ET Leader of Contract
No. HY/2013/01 on 22 January 2018 and IEC/ENPO on 24 January 2018. Alternative
air quality monitoring station AMS7B was submitted to the authority on 30
January 2018 and effective from 6 February 2018 with the authority’s consent.
6.4.13 As
informed by the Contractor, major construction activities for Contract no.
HY/2010/02 has been substantially completed and it is anticipated that
potential environmental impact for remaining works which only include ad hoc
minor maintenance/touch up works on seawall under the Contract would be
insignificant. In view of this, a proposal for Termination of EM&A
Programme was prepared and certified by ET in accordance with Condition 5.1 of EP-353/2009/K
and Condition 4.1 of EP-354/2009/D to terminate the EM&A Programme for
Contract no. HY/2010/02. The proposal has been sent to IEC/ENPO for their
further review on 17 April 2018 and IEC/ENPO verified the proposal on 18 April
2018. The proposal has been sent to authority by project team on 19 April 2018.
6.5 Summary of

8.2.1 According
to the environmental site inspections performed in the reporting month, the
following recommendations were provided:
Air Quality Impact
l All working plants
and vessels on site should be regularly inspected and properly maintained to
avoid dark smoke emission.
l
All vehicles should be washed to remove any dusty materials
before leaving the site.
l
Haul roads should be sufficiently dampened to minimize fugitive
dust generation.
l
Wheel washing facilities should be properly maintained and
reviewed to ensure properly functioning.
l
Temporary exposed slopes and open stockpiles should be properly
covered.
l
Enclosure should be erected for cement debagging, batching and
mixing operations.
l
Water spraying should be provided to suppress fugitive dust for
any dusty construction activity.
l
Regular review and provide maintenance to dust control measures
such as sprinkler system.
Construction Noise
Impact
l
Quieter powered mechanical equipment should be used as far as
possible.
l
Noisy operations should be oriented to a direction away from
sensitive receivers as far as possible.
l
Proper and effective noise control measures for operating
equipment and machinery on-site should be provided, such as erection of movable
noise barriers, enclosure for noisy plants or enhancement works to provide
sufficient acoustic decoupling measure(s). Closely check and replace the sound
insulation materials regularly
l
Vessels and equipment operating should be checked regularly and
properly maintained.
l
Noise Emission Label (NEL) shall be affixed to the air compressor
and hand-held breaker operating within works area.
l
Acoustic decoupling measures should be properly implemented for
all existing and incoming construction vessels with continuous and regularly
checking to ensure effective implementation of acoustic decoupling measures.
Water Quality
Impact
l
Regular review and maintenance of silt curtain systems, drainage
systems and desilting facilities in order to make sure they are functioning
effectively.
l
Construction of seawall should be completed as early as possible.
l
Regular inspect and review the loading process from barges to
avoid splashing of material.
l
Silt, debris and leaves accumulated at public drains, wheel
washing bays and perimeter u-channels and desilting facilities should be
cleaned up regularly.
l
Silty effluent should be treated/ desilted before discharged.
Untreated effluent should be prevented from entering public drain channel.
l
Proper drainage channels/bunds should be provided at the site
boundaries to collect/intercept the surface run-off from works areas.
l
Exposed slopes and stockpiles should be covered up properly
during rainstorm.
Chemical and Waste
Management
l
All types of wastes, both on land and floating in the sea, should
be collected and sorted properly and disposed of timely and properly. They
should be properly stored in designated areas within works areas temporarily.
l
All chemical containers, batteries and oil drums should be
properly stored and labelled.
l
All plants and vehicles on site should be properly maintained to
prevent oil leakage. Proper measures, like drip trays and/or bundings, should
be provided for retaining leaked oil/chemical from plants.
l
All kinds of maintenance works should be carried out within
roofed, paved and confined areas.
l
All drain holes of the drip trays utilized within works areas
should be properly plugged to avoid any oil and chemical waste leakage.
l
Oil stains on soil surface, accumulated oil mixture and empty chemical
containers should be cleared and disposed of as chemical waste.
l
Regular review should be conducted for working barges and patrol
boats to ensure sufficient measures and spill control kits were provided on
working barges and patrol boats to avoid any spreading of leaked oil/chemicals.
Landscape and
Visual Impact
l
All existing, retained/transplanted trees at the works areas
should be properly fenced off and regularly inspected.
l
Control night-time lighting and glare by hooding all lights.
