RECOMMENDATIONS AND CONCLUSIONS
5.1
Comments
5.1.1
Site inspections were carried out on a weekly basis
to monitor the implementation of proper environmental pollution control and mitigation
measures for the Contract. During the reporting period, 165 site inspections
(includes Contract No. HY/2013/06 within Contract No. HY/2013/03 works area)
were carried out from September 2015 to October 2018 (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, no site inspection was conducted
from November 2018).
5.1.2
Particular observations during the site inspections
are described in the monthly EM&A Reports for Contract No. HY/2013/03 (from
September 2015 to January 2019). The Contractor has rectified most of the
observations as identified during environmental site inspections during the
reporting period.
5.1.3
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.
5.2
Recommendations
5.2.1
With implementation of the recommended
environmental mitigation measures, the contract’s environmental impacts were
considered environmentally acceptable. The weekly environmental site
inspections ensured that all the environmental mitigation measures recommended
were effectively implemented.
5.2.2
The recommended environmental mitigation measures,
as included in the EM&A programme, effectively minimize the potential
environmental impacts from the Contract. Also, the EM&A programme
effectively monitored the environmental impacts from the construction
activities and ensure the proper implementation of mitigation measures. No
particular recommendation was advised for the improvement of the programme.
5.3
Conclusions
5.3.1
Commencement of Contract No. HY/2013/03 took place
on 10 April 2015 and the construction works of Contract No. HY/2013/03
commenced on 29 August 2015 (commencement of Contract No. HY/2013/06 took place
on 14 August 2015 and the construction works of Contract No. HY/2013/06
commenced on 13 September 2016 within Contract No. HY/2013/03 works area). This
is the Final EM&A Review Report summarising the findings of EM&A
activities conducted under Contract No. HY/2013/03 from 29 August 2015 to 31
January 2019 (includes the findings of EM&A activities conducted under
Contract No. HY/2013/06 within Contract No. HY/2013/03 works area from 13
September 2016 to 31 January 2019).
5.3.2
Summary of Action and Limit Level exceedance of
1-hr TSP level and 24-hr TSP level at AMS6 shall be referred to the monthly
EM&A Reports (from September 2015 to January 2019) prepared by Contract No.
HY/2011/03.
5.3.3
There
was one Action Level exceedance of 24-hr TSP level recorded at station AMS3B by
the Environmental Team of Contract No. HY/2013/01 on 28 November 2017, one Action
Level exceedance of 24-hr TSP level recorded at station AMS3B by the
Environmental Team of Contract No. HY/2013/01 on 23 December 2017, and two
Action Level exceedances of 24-hr TSP level recorded at station AMS2 and AMS3B
by the Environmental Team of Contract No. HY/2013/01 on 17 January 2018 during
the reporting period. After investigation, it was concluded that all
exceedances were not relevant to Contract No. HY/2013/03.
5.3.4
There was no Action and Limit Level exceedance of
1-hr TSP level and 24-hr TSP level recorded on other monitoring dates at
station AMS2, AMS3B/AMS3C and AMS7/AMS7A/AMS7B by the Environmental Team of
Contract No. HY/2010/02 (from September 2015 to August 2017), Contract No.
HY/2013/01 (from September 2017 to September 2018), and Contract No. HY/2013/04
(from October 2018 to January 2019).
5.3.5
There was no Action and Limit Level exceedance for
noise recorded at station NMS2 and station NMS3B/NMS3C by the Environmental
Team of Contract No. HY/2010/02 (from September 2015 to August 2017), Contract
No. HY/2013/01 (from September 2017 to September 2018), and Contract No.
HY/2013/04 (from October 2018 to January 2019) during the reporting period.
5.3.6
There were Action and Limit Level exceedances
recorded at different WQM stations recorded on 90 days (marine works were conducted as silt
curtain was installed on 11 May 2017 for Contract No. HY/2013/03 and therefore,
water quality impact monitoring result is reported from May 2017) by the
Environmental Team of Contract No. HY/2010/02 (from May 2017 to August 2017),
Contract No. HY/2013/01 (from September 2017 to September 2018), and Contract
No. HY/2013/04 (from October 2018 to January 2019) during the reporting period.

5.3.7 After
investigation, it was concluded that all exceedances were not relevant to
Contract No. HY/2013/03. There was no Action and Limit Level exceedance recorded
on other monitoring dates at the monitoring stations as shown at Table 2.2 by the Environmental Team of
Contract No. HY/2010/02 (from May 2017 to August 2017), Contract No. HY/2013/01
(from September 2017 to September 2018), and Contract No. HY/2013/04 (from
October 2018 to January 2019) during the reporting period.
5.3.8 Ecological
monitoring results at all transects are reported in the EM&A Reports (marine works were conducted as silt curtain
was installed on 11 May 2017 for Contract No. HY/2013/03 and therefore,
ecological monitoring result is reported from May 2017) prepared by
Contract No. HY/2010/02 (from May 2017 to August 2017), Contract No. HY/2013/01
(from September 2017 to September 2018), and Contract No. HY/2013/04 (from
October 2018 to January 2019).
5.3.9 Eight Limit Level exceedances
were recorded for ecological monitoring at all transects by the Environmental
Team of Contract No. HY/2010/02 (from May 2017 to August 2017), Contract No.
HY/2013/01 (from September 2017 to September 2018) and Contract No. HY/2013/04
(from October 2018 to January 2019) during the reporting period. The following

5.3.10 There was no Action Level exceedance
recorded on other monitoring dates for ecological monitoring at all transects
by the Environmental Team of Contract No. HY/2010/02 (from May 2017 to August
2017), Contract No. HY/2013/01 (from September 2017 to September 2018) and
Contract No. HY/2013/04 (from October 2018 to January 2019) during the reporting period.
5.3.11 Environmental
site inspection was carried out during the reporting period (includes Contract
No. HY/2013/06 within Contract No. HY/2013/03 works area). Recommendations on
remedial actions were given to the Contractors for the deficiencies identified
during the site inspections.
5.3.12 There
were fifteen complaints received in relation to the environmental impact during
the reporting period. After investigation, all the complaints were not related
to Contract No. HY/2013/03.
5.3.13 There
were no notifications of summons or prosecutions received during the reporting
period.
5.3.14 As
informed by the Contractor, all major construction activities for Contract No.
HY/2013/03 have been substantially completed and only minor maintenance works
will be carried out on site upon request. All land areas have been handed over
to relevant responsible parties. The EM&A requirement of landscape soft
works for establishment phase was appropriately arranged. After reviewing the
existing environmental conditions of the site, it is considered that the
potential environmental impacts associated with the remaining works are
insignificant and therefore propose to terminate the Construction Phase
EM&A Programme under Contract No. HY/2013/03. Independent Environmental
Checker (IEC) verified the proposal for termination of EM&A programme under
Contract No. HY/2013/03 on 30 November 2018. Environmental Protection Department’s
(EPD’s) memo reference ( ) in E771/E1/100 dated 01 February 2019 informing no
comment on the proposal for termination of EM&A programme for Contract No.
HY/2013/03.
