The
dolphin survey results for all transects were reported in the monthly EM&A
Reports (for December 2017, January 2018 and February 2018) prepared by Contract No. HY/2013/01. There was no Action and Limit Level exceedance recorded by
the Environmental Team of Contract No. HY/2013/01 during the reporting period (December 2017 to
February 2018).
3.5
Implementation
of Environmental Measures
3.5.1
In response to the site audit findings, the Contractor
carried out corrective actions. Details of site audit findings and the
corrective actions during the reporting period are presented in Appendix F.
3.5.2
A summary of the Implementation Schedule of
Environmental Mitigation Measures (EMIS) is presented in Appendix E. All necessary mitigation measures at this stage of
works were implemented properly.
3.5.3
Implementation
status of Regular Marine Travel Route Plan (RMTRP) was checked by ET. In
general, the Contractor has complied with the plan. 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 from December
2017 to February 2018 were checked by ET. The marine traffic records and
geographical plots of all the vessels tracks to demonstrate the conformance of
the vessel to the proposed route in December 2017, January 2018 and February
2018 were provided by Contractor to ER, IEC/ENPO for checking within the month
of January 2018, February 2018 and March 2018 respectively. 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.
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. Under Contract No.
HY/2013/03, no floating
concrete batching plant was operated on-site during the reporting period.
3.5.5
As silt
curtain was installed since May 2017, Dolphin Watching Plan (DWP) should be
implemented. The status of silt curtain was reviewed by ET and there was no
change on the status of silt curtain during the reporting period.
Implementation status of DWP was checked by ET. The records of dolphin watching
training, regular inspection of the silt curtains and visual inspection of
waters surrounded by the silt curtain in December 2017, January 2018 and February
2018 would be provided to ER, ETL, IEC/ENPO for checking within the month of
January 2018, February 2018 and March 2018 respectively.
3.5.6
The landscape work of green roof for Contract No.
HY/2013/03 was commenced on 07 November 2017. 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.
Landscape and visual mitigation measures in accordance with the EP, EIA and
EM&A Manual were implemented by the Contractor.

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. No marine sediment extracted from this Contract was disposed to the Marine
Fill Committee (MFC) allocated disposal sites directly without treatment during
this 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 Vd of the Confined Marine
Sediment Disposal Facility to the East of Sha Chau (ESC).
3.6.5
No marine sediment extracted from bored piling from
this Contract was disposed to allocated dumping site during this 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:

(TM-CLKL) project of HZMB, the Airport Authority Hong Kong’s Three Runway (3RS)
Project, Wan Chai Development Phase II Project, Contract No. HY/2013/02 of
HKBCF and Hong Kong Link Road (HKLR) project of HZMB. The estimated quantity of
surplus filling materials is confirmed by Resident Site Staff of Contract No.
HY/2013/03. The summary of surplus filling materials delivered to other projects
up to the end of February 2018 is shown in Table

ž There may be discrepancies in the total quantities with the quantities of
inert C&D materials stated in Appendix G, due to rounding errors
ž No density was given from October 2017 to February 2018 due to the direct
