Executive Summary
The Hong Kong-Zhuhai-Macao
Bridge (HZMB) Hong Kong Link Road (HKLR) serves to connect the HZMB Main Bridge
at the Hong Kong Special Administrative Region (HKSAR) Boundary and the HZMB
Hong Kong Boundary Crossing Facilities (HKBCF) located at the north eastern
waters of the Hong Kong International Airport (HKIA).
The HKLR project has been
separated into two contracts. They
are Contract No. HY/2011/03 Hong Kong-Zhuhai-Macao Bridge Hong Kong Link
Road-Section between Scenic Hill and Hong Kong Boundary Crossing Facilities
(hereafter referred to as the Contract) and Contract No. HY/2011/09 Hong
Kong-Zhuhai-Macao Bridge Hong Kong Link Road-Section between HKSAR Boundary and
Scenic Hill.
China State Construction
Engineering (Hong Kong) Ltd. was awarded by Highways Department as the
Contractor to undertake the construction works of Contract No. HY/2011/03. The main works of the Contract include land
tunnel at Scenic Hill, tunnel underneath Airport Road and Airport Express Line,
reclamation and tunnel to the east coast of the Airport Island, at-grade road
connecting to the HKBCF and highway works of the HKBCF within the Airport
Island and in the vicinity of the HKLR reclamation. The Contract is part of the HKLR Project
and HKBCF Project, these projects are considered to be ˇ§Designated Projectsˇ¨,
under Schedule 2 of the Environmental Impact Assessment (EIA) Ordinance (Cap
499) and Environmental Impact Assessment (EIA) Reports (Register No.
AEIAR-144/2009 and AEIAR-145/2009) were prepared for the Project. The current Environmental Permit (EP)
EP-352/2009/A for HKLR and EP-353/2009/E for HKBCF were issued on 31 October
2011 and 16 October 2012, respectively. These documents are available through
the EIA Ordinance Register. The construction phase of Contract was
commenced on 17 October 2012.
BMT Asia Pacific 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 HKLR (Version 1.0) and will be providing
environmental team services to the Contract.
This is the first Quarterly
EM&A report for the Contract which summaries the monitoring results and
audit findings of the EM&A programme during the reporting period from 1 October to 30 November 2012.
In order to compare the data analysis for dolphin monitoring results to
the baseline monitoring results and the AFCDˇ¦s quarterly monitoring results, this
first quarterly report will contain two monthsˇ¦ monitoring data instead of
three. The Quarterly EM&A
reports thereafter will contain three monthsˇ¦ monitoring data.
Environmental Monitoring and Audit Progress
The EM&A programme were undertaken in accordance with the Updated
EM&A Manual for HKLR (Version1.0).

The Environmental Team
investigated all exceedances and found that they were not project related.
All investigation reports
for exceedances of the Contract have been submitted to ENPO/IEC for comments
and/or follow up to identify whether the exceedances occurred related to other
HZMB contracts.
Implementation of
Mitigation 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.

of the water quality limit occurs when monitoring result is lower that the
limit.
(3) For SS & turbidity
non-compliance of the water quality limits occur when monitoring result is
higher than the limits.
