several water quality monitoring (WQM) stations including IS10, SR5 and CS(Mf)3 will be occupied by the marine works
of a designated project - Expansion of Hong Kong International Airport into a
Three-Runway System (3RS Project), alternative WQM stations
named as IS10(N),
SR5(N)
and CS(Mf)3(N)
were proposed to replace the occupied stations. The proposal for changes of the EM&A Programme was justified and verified by the ET
Leader for Contract No. HY/2010/02 and the IEC respectively on 24 March
2017, and it was approved by EPD on 12 May 2017. Besides, due to topographical conditions of SR3, SR10A and SR10B(N),
the water quality monitoring (WQM) stations was proposed to be monitored at
alternative WQM stations named as SR3(N), SR10A(N)
and SR10B(N2). The proposal for alternation of water
quality monitoring stations for HZMB HKBCF was justified by the ET
Leader for Contract No. HY/2013/01 on 08 November 2017 and verified by the
IEC on 13 November 2017; and submitted to EPD on 29 November 2017, and it was
approved by EPD on 22 December 2017. Table 2.2 and Figure 2 shows the locations of water quality monitoring stations.

Disposal of Marine Sediment
3.7.1 For the marine sediment
disposal, after the acceptance of the review of the approved Sediment Quality
Report (SQR) for this Project under EPD letter dated 19 August 2015, an
approval to dispose the marine sediment extracted from bored piling for this
Project was then approved under memo from Secretary, Marine Fill Committee of
CEDD dated 20 August 2015 for the disposal of marine sediment extracted from
bored piling works. The disposal sites allocated to this Project are the Mud
Pit CMP2 of the Confined Marine Sediment Disposal Facility to the South of The
Brothers (or at the East of Sha Chau).
As advised by CEDD in the memo dated 19 February 2016, from 00:00 on 22 March
2016 onward, the disposal space at CMP2 of the South of The Brothers is closed
and all disposal of contaminated sediment is to be carried out at CMP Vd to the East of Sha Chau (ESC). As a practical means, the disposal operation is
managed by one contractor who is also responsible for applying dumping permit
and its subsequent extension applications from EPD. Contract No. HY/2013/03 has
been assigned to coordinate and arrange for disposal of extracted marine
sediment from Contract No. HY/2013/02, HY/2013/03 and HY/2013/04.
3.7.2 For the dumping
arrangement, the barge for disposal of marine sediment will moor at the
temporary loading and unloading at the east shore of the HKBCF Island, which
has been being used by contractor Contract No. HY/2010/02 for reclamation
activities. In terms of safety consideration and to avoid mixing of sediment
between contracts, each dumping date will be allocated to one Contract. The
quantity of marine sediment disposed on each date is from one Contract.
3.7.3 During dumping, HY/2013/02
is responsible for transporting the marine sediment from his site area to the
barge by Land transportation. The estimated quantity of marine sediment in each
truck is confirmed by Resident Site Staff of each
Contract. The trip tickets for transportation and disposal of marine sediment
are collected and checked. Contract No. HY/2013/03 as the dumping permit holder
is responsible for reporting to EPD the quantity disposed of as the
condition stipulated in the dumping permit.
3.7.4 The Summary of Marine sediment
disposed to dumping site was provided in Appendix F and Table 3.6.

Site Inspection
3.8.1 According to the
Environmental Monitoring and Audit Manual, regular environmental site
inspections was carried out by ET joined with RE and the Contractor to
confirm the environmental performance.
3.8.2 During the construction period, 208 events of joint site inspections
were undertaken by the RE,
EO and ET to evaluate the site environmental performance. No adverse
environmental impacts were registered, indicating that mitigation measures
implemented were effective and sufficient for the construction activities
undertaken. Minor deficiencies found during site inspections and audits
were rectified
by specified deadlines. The observations of each site inspection can be found in their
relevant EM&A monthly reports.
3.8.3 As confirmed by RSS on 16 January 2018, the
landscape construction works including planting (Shrubs &
Grass), installation of irrigation pipe and soiling (Sub & Top soil) for Contract No. HY/2013/02 were commended on 04 November 2017. The landscape inspections were
conducted on a bi-weekly
basis during the weekly environmental site inspection.
3.8.4 During the site inspections, there was no conflict occurred regarding to the Landscape & Visual mitigation measures stated in Contract Specific EM&A Manual.
The work site was found to be confined within site boundaries and grass-hydroseed was provided for bare soil surface and stock pile
areas. Landscape & Visual mitigate measures during construction would be checked to ensure compliance with the
intended aims of the measures.
