Under Contract No. HY/2012/07,
Gammon Construction Limited (GCL) is commissioned by the Highways Department (HyD) to undertake the design and construction of the Southern
Connection Viaduct Section of the Tuen Mun ¡V Chek Lap Kok Link Project (TM-CLK Link Project) while AECOM
Asia Company Limited was appointed by HyD as the
Supervising Officer. For
implementation of the environmental monitoring and audit (EM&A) programme under the Contract, ERM-Hong Kong, Limited (ERM)
has been appointed as the Environmental Team (ET). ENVIRON Hong Kong Ltd. was employed by
the HyD as the Independent Environmental Checker
(IEC) and Environmental Project Office (ENPO) in accordance with Environmental Permit No. EP-354/2009/A. Further applications for variation of
environmental permit (VEP), EP-354/2009/B, EP-354/2009/C and EP-354/2009/D, were granted on 28 January 2014, 10 December 2014
and 13 March 2015, respectively.
The
construction phase of the Contract commenced on 31 October 2013 and will tentatively
be completed by 2018. The impact
monitoring of the EM&A programme, including air
quality, noise, water quality and marine ecological monitoring as well as
environmental site inspections, commenced on 31 October 2013.
This
is the Seventeenth Monthly EM&A report presenting the EM&A works
carried out during the period from 1 to 31 March 2015 for the Southern
Connection Viaduct Section in accordance with the Updated EM&A Manual of the
TM-CLK Link Project. As informed by the Contractor, major
activities in the reporting period included:

Breaches of Action and Limit Levels for Air Quality
No exceedance
of Action and Limit Levels was recorded for construction air monitoring in the
reporting month.
Breaches of Action and Limit Levels for Noise
No exceedance
of Action and Limit Levels was recorded for construction noise monitoring in
the reporting month.
Breaches of Action and Limit Levels for Water Quality
No exceedance
of Action and Limit Levels was recorded for impact water quality monitoring in
the reporting month.
Impact Dolphin Monitoring
During
this month of dolphin monitoring, no unacceptable impact from the construction
activities of the TM-CLKL Southern Connection Viaduct Section on Chinese White
Dolphins was noticeable from general observations. Due to monthly variation in dolphin
occurrence within the study area, it would be more appropriate to draw
conclusion on whether any impacts on dolphins have been detected related to the
construction activities of the TM-CLKL Southern Connection Viaduct Section in
the quarterly EM&A reports, where comparison on distribution, group size
and encounter rates of dolphins between the quarterly impact monitoring period
and baseline monitoring period will be made.
Daily
marine mammal exclusion zone monitoring was undertaken during the period of
marine works under this Contract. No Passive Acoustic Monitoring (PAM) was implemented
as the marine works were not carried out outside the daylight hours in this
reporting month. No sighting of the Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in March 2015 during the exclusion
zone monitoring.
Environmental Complaints, Non-compliance & Summons
No environmental
complaint, notification of summons and successful prosecution was received in
the reporting month.
Reporting Change
The
weekly monitoring for landscape and visual impact mitigation measures will be
reported in a separated checklist instead of reported in the weekly checklist with
other mitigation measures, and the status of landscape and visual impact
mitigation measures will be summarized in the EMIS of the EM&A Monthly Report.
The aforementioned procedure will be undertaken in April 2015.

Future Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of April 2015 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
According to
the findings of the Northwest New Territories (NWNT) Traffic and Infrastructure
Review conducted by the Transport Department, Tuen Mun Road, Ting Kau Bridge, Lantau
Link and North Lantau Highway would be operating beyond capacity after
2016. This forecast has been based
on the estimated increase in cross boundary traffic, developments in the
Northwest New Territories (NWNT), and possible developments in North Lantau,
including the Airport developments, the Lantau Logistics Park (LLP) and the
Hong Kong ¡V Zhuhai ¡V Macao Bridge (HZMB).
In order to cope with the anticipated traffic demand, two new road
sections between NWNT and North Lantau ¡V Tuen Mun ¡V Chek Lap Kok Link (TM-CLKL) and Tuen Mun Western Bypass (TMWB) are proposed.
An
Environmental Impact Assessment (EIA) of TM-CLKL (the Project) was prepared in
accordance with the EIA Study Brief (No. ESB-175/2007) and
the Technical Memorandum of the
Environmental Impact Assessment Process (EIAO-TM). The
EIA Report was submitted under the Environmental Impact Assessment Ordinance
(EIAO) in August 2009. Subsequent
to the approval of the EIA Report (EIAO Register Number AEIAR-146/2009), an
Environmental Permit (EP-354/2009)
for TM-CLKL was granted by the Director of Environmental Protection (DEP) on 4
November 2009, and EP variation (EP-354/2009/A)
was issued on 8 December 2010.

Although
some results of depth-averaged SS were recorded higher than the values of
Action Level or Limit Level in the monitoring period, the results were not
higher than 120% of the upstream control at the same tide of the same day. Thus the results were considered as
natural variation. No Action and
Limit levels exceedances was recorded at all monitoring stations for impact
water quality monitoring in the reporting month. No action is thus required to be
undertaken in accordance with the Event Action Plan presented in Appendix L.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of April 2015 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This Seventeenth
Monthly EM&A Report presents the findings of the EM&A activities
undertaken during the period from 1 to 31 March 2015, in accordance with the
Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/D).
Four (4) groups
of twelve (12) Chinese White Dolphins were sighted during the two sets of
monitoring surveys in March 2015. All
sightings were made in NWL, with no dolphin being sighted at all in NEL. No sighting was made in the proximity of
the Project¡¦s alignment. During this month of dolphin monitoring, no
unacceptable impact from the construction activities of the TM-CLKL Southern
Connection Viaduct Section on Chinese White Dolphins was noticeable from
general observations.
The ET will
keep track on the construction works to confirm compliance of environmental
requirements and the proper implementation of all necessary mitigation
measures.
