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 Sixth 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 March 2016 to 31 May 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
inspections during the reporting period are listed below:

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.
Although the marine construction
works of temporary loading and unloading point was
completed in December 2015 and no marine works was carried out during this reporting
period, water quality monitoring and impact dolphin monitoring are still
required in this reporting month.
There was one Limit Level
exceedance of SS on impact water quality monitoring at station SR4(N) during
mid-flood tide recorded on 20 May 2016. After investigation, there was
concluded that the exceedances were not relevant to this Contract since there
was no marine works carried out by this Contract during the reporting period. There was no Action and Limit
Level exceedance recorded on other 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. 003 (including the causes of exceedance, action taken and recommendation
for mitigation) for Action or Limit Level Non-compliance was 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.
Implementation of Environmental
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.
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 notification of summon or prosecution received during the reporting period.
Reporting
Change
The Environmental Permit (EP) was
updated from No. EP-353/2009/J to No. EP-353/2009/K for HKBCF which was applied
on 24 March 2016 and was issued on 11 April 2016. These documents are available
through the EIA Ordinance Register.

2.1 Summary of EM&A Requirements
The ET of the Contract or another ET of the HZMB project is required to
conduct dolphin monitoring at 23 transects as part of EM&A programme if
these transects are no longer covered under Contract No. HY/2010/02. The dolphin monitoring should adopt line-transect
vessel survey method. The survey follows pre-set and fixed transect lines in the
two areas defined by AFCD as: Northeast Lantau survey area; and
