of Contract No. HY/2013/06 within Contract No. HY/2013/03 works area).
3.5.2 A
summary of the Implementation Schedule of Environmental Mitigation Measures
(EMIS) is presented in Appendix E.
All necessary mitigation measures were implemented properly during the
reporting period.
3.5.3 Implementation
status of Regular Marine Travel Route Plan (RMTRP) was checked by ET. Training
of marine travel route for marine vessels operator was given to relevant staff
and relevant records were kept properly. Marine traffic records which indicated
the number of trips data for pelican barge, hopper barge, tug boat, floating
concrete batching plant and derrick lighter on the implementation of RMTRP were
checked by ET. Marine traffic records and geographical plots of all the vessels
tracks to demonstrate the conformance of the vessel to the proposed route were
provided by Contractor to ER, ETL, IEC/ENPO for checking
during the reporting period. The implementation of marine traffic follows the
Regular Marine Travel Route Plan with respect to ET¡¦s checking on the marine
traffic records for the reporting period. As confirmed by RSS, all surplus
filling materials transported from Contract No. HY/2013/03 to other projects by
marine vessels have been completed with the last batch delivered on 07 May 2018.
3.5.4 With
respect to condition 3.26A of EP-353/2009/K approved by EPD on 11 April 2016,
the numbers and operating periods of floating grout production facilities and
floating concrete batching plants on-site to review on the compliance to this
EP condition were checked during the reporting period.
3.5.5 Dolphin
Watching Plan (DWP) was implemented as silt curtain was installed on 11 May
2017. Implementation status of DWP was checked by ET. Before the installation
of silt curtain, ET conducted visual inspection of the presence of dolphins in
the surrounding water. Besides, dolphin watching training was provided to the
representatives of the Contractor during April 2017. The records of dolphin
watching training, regular inspection of the silt curtains and visual
inspection of waters surrounded by the silt curtain were provided to ER, ETL, IEC/ENPO for checking during the reporting period. The
status of silt curtain was reviewed by ET and there was no change on the status
of silt curtain during the reporting period. As all the works in Box Culvert B
had been completed, the silt curtain was uninstalled. The Dolphin Watching Plan
(DWP) is no longer applicable.
3.5.6 The
landscape work of green roof for Contract No. HY/2013/03 was commenced on 07 November
2017. The landscape work of all areas at ground level for Contract No.
HY/2013/03 was commenced at early February 2018. Detail commencement date of
each building were shown in Table 3.2.
The implementation of mitigation measures for landscape and visual resources
recommended in the EIA Report were monitoring during the reporting period
(until 24 October 2018). Landscape and visual mitigation measures in accordance
with the EP, EIA and EM&A Manual were implemented by the Contractor. As all
the sections under Contract No. HY/2013/03 (includes Contract No. HY/2013/06 within
Contract No. HY/2013/03 works area) were handed over to the relevant
authorities on 24 October 2018 and the site had been changed to a closed area,
the implementation of mitigation measures for landscape and visual resources
recommended in the EIA Report could not be monitored from 24 October 2018.

3.6 Advice on
the Solid and Liquid Waste Management Status
3.6.1 The
Contractor of Contract No. HY/2013/03 registered as a chemical waste producer
for the Contract. Sufficient numbers of receptacles were available for general
refuse collection and sorting.
3.6.2
No extracted marine sediment was treated using cement solidification/stabilisation
(Cement S/S) techniques under Contract No. HY/2013/03 during this reporting
period. Marine sediment extracted from this Contract was disposed to the Marine
Fill Committee (MFC) allocated disposal sites directly without treatment during
the reporting period. As a practical mean, 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 all three Contracts (Contract Nos. HY/2013/02, HY/2013/03 and HY/2013/04).
3.6.3 The
barge for disposal of marine sediment was morn at the temporary loading and
unloading at the east shore of the HKBCF Island, which has been being used by
reclamation 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 was allocated to one Contract. The quantity of
marine sediment disposed on each date was from one Contract.
3.6.4 During
dumping, Contractor of Contract No. HY/2013/03 is responsible for transporting
the marine sediment from the site area of Contract No. HY/2013/03 to the barge.
The estimated quantity of marine sediment in each truck is confirmed by Resident
Site Staff of Contract Nos. HY/2013/02, HY/2013/03 and HY/2013/04. 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. The disposal site allocated to this Project are the Mud Pit CMP
Va and the Mud Pit CMP2 of the Confined Marine
Sediment Disposal Facility to the South of The Brothers, and Mud Pit CMP Vd of the Confined Marine Sediment Disposal Facility to the
East of Sha Chau (ESC) during the reporting period.
3.6.5 Marine
sediment extracted from bored piling from this Contract was disposed to
allocated dumping site during the reporting period. As confirmed by RSS, all
marine sediments extracted from HY/2013/02, HY/2013/03 and HY/2013/04 have been
completed with the last batch disposal on 30 August 2017. The summary of marine
sediment disposed during this reporting period is shown in the following table:
