This Quarterly Environmental Monitoring and Audit (EM&A) Report is prepared for Contract HY/2013/02
Hong Kong-Zhuhai-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
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 Fifth Quarterly 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 December 2015 to 29 February 2016.
Environmental Monitoring and Audit Progress
The EM&A programme was
undertaken in accordance with the Updated EM&A Manual for HKBCF (Version
1.0). It should be noted that the air quality and noise monitoring works for
the Contract are covered by Contract No. HY/2010/02 ¡§Hong Kong-Zhuhai-
The dates of environmental site

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 AMS
There was no
Action and Limit Level exceedance of 1-hr
TSP level and 24-hr TSP level recorded at station AMS
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.
Since the marine construction works of
temporary loading and unloading point was carried out from 02 Dec 2015 to 30
Dec 2015, water quality monitoring and impact dolphin monitoring are required
from this reporting month.
For water quality monitoring, there
were three exceedances recorded during the reporting period. One Action Level exceedance of SS at IS(Mf)11 during mid-flood tide was recorded
on 28 Dec 2015 and one Action Level exceedance of SS and
one Limit Level exceedance of Turbidity on impact water quality
monitoring at station SR4(N)
during mid-flood tide recorded on 05 Feb 2016. After investigation, there was
concluded that the exceedances were not relevant to this Contract. There was no
Action and Limit Level exceedance recorded on other monitoring date
at the monitoring stations showed in Table 2.2 by the
Environmental Team of Contract No. HY/2010/02 during the reporting period. The Investigation Report No. 002
(including the causes of exceedance, action taken and recommendation for
mitigation) on Action or Limit Level Non-compliance is provided in Appendix J.
Impact dolphin monitoring results at all transects are reported in the
EM&A Report prepared for Contract No. HY/2010/02. One limit level
exceedance was recorded in the Monitoring Period (Dec 2015 ¡V Feb 2016). The
investigation is undergoing and investigation results is referred in quarterly
report (Dec 2015 ¡V Feb 2016) of Contract No. HY/2010/02.

Measures
Site
inspections were carried out on a weekly basis to monitor the implementation of
proper environmental pollution control and mitigation measures for the Project.
Potential environmental impacts due to the construction activities were
monitored and reviewed.

One Action Level exceedance of SS at
IS(Mf)11 during mid-flood tide was recorded on 28 Dec 2015. After
investigation, there is no adequate information to conclude the recorded
exceedance is related to this Contract. The Investigation Report No. 002 (including
the causes of exceedance, action taken and recommendation for mitigation) on
Action or Limit Level Non-compliance is provided in Appendix J.
3.3.4 05 Feb 2016
There were
one Action
Level exceedance of SS and one Limit Level exceedance of Turbidity on impact
water quality monitoring at station SR4 (N) during mid-flood tide recorded on
05 February 2016. Exceedance was not due to operation of the works under
Contract No. HY/2013/02 because 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 SR4(N) from 02 to 05
February 2016 which was unlikely to generate suspended solids in the marine
water. Secondly, the SS and Turbidity exceedances were recorded during flood
tide in which the monitoring station SR4(N) is located at upstream of the works
area of this Contract. Therefore, it is unlikely that the SS and Turbidity
exceedances recorded at SR4(N) during mid-flood tide on 05 February 2016 was
contributed by the works under Contract No. HY/2013/02. 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 etc. After investigation, there was concluded that the
exceedances were not relevant to this Contract due to the above mentioned
reasons. The Investigation Report (including the causes of exceedance, action
taken and recommendation for mitigation) for Action or Limit Level
Non-compliance was prepared by the ET of Contract No. HY/2010/02 and detailed
in the monthly EM&A Report prepared for Contract No. HY/2010/02. There was
no Action and Limit Level exceedance on other monitoring date was recorded by

Regarding to the marine
construction work, the steel piles installation works was carried out at the
temporary loading and unloading point in Portion A1 during the December
2015. All the installation was within the silt curtains and there was no any
Chinese White Dolphin (CWD) was found within the Dolphin Exclusion Zone during
the reporting period.
