This Monthly Environmental
Monitoring and Audit (EM&A) Report is
prepared for Contract HY/2013/02 ¡§Hong Kong¡VZhuhai-Macao Bridge Hong Kong
Boundary Crossing Facilities (HKBCF) ¡V Infrastructure Works Stage I (Western
Portion)¡¨ (hereafter referred to as ¡§the Contract¡¨) for the Highways Department
of Hong Kong Special Administrative Region (HKSAR). The Contract was awarded to
China Harbour Engineering Co., Ltd. (hereafter referred to as ¡§the Contractor¡¨)
and ETS-Testconsult Limited was appointed as the Environmental Team (ET) by the
Contractor.
The Contract is part of Hong Kong¡VZhuhai¡VMacao
Bridge HKBCF which is a ¡§Designated Project¡¨, under Schedule 2 of the
Environmental Impact Assessment Ordinance (EIAO) (Cap 499) and Environmental
Impact Assessment (EIA) Report (Register No. AEIAR-145/2009) was prepared for
the Project. The current Environmental Permit (EP) No.
EP-353/2009/K for HKBCF was issued on 11 April 2016. These documents are
available through the EIA Ordinance Register. Site preparation works of the
Contract was started on 25 July 2014 and the construction works of the Contract
commenced on 24 November 2014.
ETS-Testconsult Limited has been appointed by
the Contractor to implement the Environmental Monitoring & Audit (EM&A)
programme for the Contract in accordance with the Updated EM&A Manual for
HKBCF (Version 1.0) and provide environmental team services to the Contract.
This is the Twenty-ninth Monthly Environmental
Monitoring and Audit (EM&A) Report for the Contract which summaries
findings of the EM&A works conducted during the reporting
period from 01 April
to 30 April
2017.

the Contract are covered by Contract No. HY/2010/02 ¡§Hong Kong-Zhuhai-
Environmental Site Inspection:
05, 13, 20
& 27 April 2017
Breaches of
Action and Limit Levels
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 report prepared by Contract No.
HY/2011/03.
There was no Action and Limit Level exceedance
of 1-hr TSP level and 24-hr TSP level
recorded at station AMS7 by the Environmental Team of Contract No. HY/2010/02 during the reporting period.
There was no Action and Limit Level exceedance
for noise recorded at
station NMS2 and station NMS3B by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
There
was one action level exceedance of suspended
solid on impact
water quality monitoring at station IS(Mf)11 during
mid-flood tide recorded
on 28 April 2017. After investigation, there was concluded that the exceedance
was not
relevant to this Contract since there was no marine works or barge of this Contract worked at HKBCF
reclamation site near the sea area or area near the monitoring station IS(Mf)11
from 26 April 2017 to the
water quality monitoring period on 28 April 2017 which was
unlikely to generate suspended solid
to cause the suspended solid exceedance recorded at the monitoring station IS(Mf)11 during mid-flood tide on 28 April 2017. The Investigation Reports No. 016
(including the
causes of exceedance, action taken and recommendation for mitigation) for
Action or Limit Level Non-compliance were provided in Appendix J. There
was no Action
and Limit Level
exceedance recorded on other monitoring date at the monitoring
stations showed at Table 4.1 by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
Impact
dolphin monitoring results at all transects are reported in the EM&A Report
prepared for Contract No. HY/2010/02.
Complaint Log
There was no
complaint received in relation to the environmental impact during the reporting period.
Notifications of Summons and Successful
Prosecutions
There were no
notifications of summons or prosecutions received during the reporting period.
Reporting Change
There were no
reporting changes during the reporting period.

|||
Notes: 1. "depth-averaged" is
calculated by taking the arithmetic means of reading of all three depths. |
|||
2. For DO, non-compliance of the water quality
limits occurs when monitoring result is lower than the limits. |
|||
3. For turbidity, SS, non-compliance of the water quality limits occurs
when monitoring result is higher than the limits. |
|||
4. All the figures given in the table are used for
reference only and the EPD may amend the figures whenever it is considered as
necessary. |

Monitoring Result
4.3.1
The monitoring results for the
monitoring stations showed in Table 4.1 are reported in the monthly
EM&A Report prepared for Contract No. HY/2010/02. There was one action level exceedance of suspended on impact water quality
monitoring at station IS(Mf)11 during mid-flood tide recorded on 28 April 2017.
4.3.2
The
exceedance was not relevant
to this Contract since there was no marine works or barge of this Contract worked at HKBCF reclamation site near the sea
area or area near the monitoring station IS(Mf)11 from 26 April 2017 to the water quality monitoring period on 28 April 2017
which was unlikely to generate suspended solid
to cause the suspended solid exceedance recorded at the monitoring station IS(Mf)11
during mid-flood on 28 April 2017. The water quality mitigation
measures as mentioned in EM&A Manual and EP was fully implemented in this
Contract which including maintenance of the silt curtain on a daily basis by Contract No. HY/2010/02 etc. Hence, the exceedance was considered as non-Project related.
4.3.3
After
investigation, there was concluded that the exceedance was not relevant to this
Contract due to the above mentioned reasons. The Investigation Reports No. 016
(including the causes of exceedance, action taken and recommendation for
mitigation) for Action or Limit Level Non-compliance were provided in Appendix J. There was no Action and
Limit Level exceedance recorded on other date at the monitoring stations showed
in Table 4.1 by the Environmental
Team of Contract No. HY/2010/02 during the reporting period.
4.3.4
Although the exceedance was not relevant to this
Contract, the Contractor was reminded to ensure that the maintenance of
perimeter silt curtains with respect to the work boundary of this Contract
carried out by the Contractor of Contract
No. HY/2010/02 is maintained properly.

8.1 Conclusions
8.1.4
There was no Action and Limit Level exceedance
for noise recorded at
station NMS2 and station NMS3B by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
8.1.5
There was one action level exceedance of suspended
solid on impact water quality monitoring at station IS(Mf)11
during mid-flood tide recorded on 28 April 2017. After investigation, there was concluded that the exceedance was not relevant to this Contract since
there was no marine works or barge of
this Contract worked at HKBCF reclamation site near the sea area or area near
the monitoring station IS(Mf)11 from 26 April 2017
to the water
quality monitoring period on 28 April 2017 which was unlikely to generate suspended solid to cause the suspended solid exceedance recorded
at the monitoring station IS(Mf)11 during mid-flood on 28 April 2017. The
Investigation Reports No. 016 (including the causes of exceedance, action taken and
recommendation for mitigation) for Action or Limit Level Non-compliance were
provided in Appendix J. Although the exceedance was not relevant to this Contract,
the Contractor was reminded to ensure that maintenance of perimeter silt
curtains with respect to the work boundary of this Contract carried out by the
Contractor of Contract No. HY/2010/02 is maintained properly.
