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 – 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). Ramboll 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 southern landfall of TM-CLK Link lies alongside
the Hong Kong - Zhuhai - Macao Bridge Hong Kong Boundary Crossing Facilities
(HKBCF) where a reclamation area is constructed by Contract No. HY/2010/02
under Environmental Permit No. EP-353/2009/K and EP-354/2009/D. Upon the agreement and confirmation between
the Supervising Officer Representatives and Contractors of HY/2010/02 and HY/2012/07
in September 2015, part of the reclamation area for southern landfall under EP-353/2009/K and EP-354/2009/D was handed-over to Contract No. HY/2012/07. Another part of the southern landfall area
under EP-354/2009/D was handed-over
to Contract No. HY/2012/07 after
completion of reclamation works by Contract
No. HY/2010/02 in June 2016.
The construction phase of the Contract commenced on 31
October 2013 and will be tentatively 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 Thirty-fourth Monthly EM&A report
presenting the EM&A works carried out during the period from 1 to 31 August
2016 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:
Marine Works
· Uninstallation
of marine piling platform;
· Pier
construction;
· Launching
gantry operation; and
· Installation
of deck segment and pier head segment.
Land-based Works
· Pier
construction;
· Re-alignment
of Cheung Tung Road;
· Construction
of land section of berth at Southern Landfall;
· Installation
of pier head and deck segments; and
· Slope
work of Viaducts A, B & C.
A summary of monitoring and audit activities conducted
in the reporting period is listed below:
24-hour TSP Monitoring 6 sessions
1-hour TSP Monitoring 6 sessions
Noise Monitoring 6
sessions
Impact Water Quality Monitoring 12 sessions
Impact Dolphin Monitoring 2 sessions
Joint Environmental Site Inspection 4 sessions
Breaches of
Action and Limit Levels for Air Quality
No exceedance of Action and Limit Levels was recorded
for construction air quality 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 water quality impact monitoring in the reporting period.
Impact Dolphin
Monitoring
One (1) Limit Level exceedance was
observed for the quarterly dolphin monitoring data between June and August
2016, whilst 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 sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in August 2016 during the exclusion
zone monitoring.
Environmental
Complaints, Non-compliance & Summons
There was no environmental complaint, notification of
summons or successful prosecution recorded in the reporting period.
Reporting
Change
There was no reporting change in the reporting period.

upcoming construction activities in the next reporting month of September 2016
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 – Zhuhai – Macao Bridge (HZMB). In order to cope with the anticipated traffic
demand, two new road sections between NWNT and North Lantau – Tuen Mun – 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.

The Action and Limit levels of dolphin impact
monitoring are shown in Appendix D. The Event and Action plan is presented in Appendix L.
A total of 298.06 km of survey effort was collected,
with 98.9% of the total survey effort being conducted under favourable weather
conditions (i.e. Beaufort Sea State 3 or below with good visibility) during the
surveys in August 2016. Among the two
areas, 113.80 km and 184.26 km of survey effort were collected from NEL and NWL
survey areas respectively. The total
survey effort conducted on primary and secondary lines were 213.49 km and 84.57
km respectively. The survey efforts are
summarized in Appendix K.
Five (5) groups of 26 Chinese White Dolphins
were sighted during the two sets of monitoring surveys in
August 2016. All five (5) dolphin sightings were made in
NWL, while none was sighted in NEL.
During the surveys in August 2016, four (4) sightings were made on
primary lines during on-effort search.
None of the dolphin groups was associated with operating fishing vessel
or sighted in the proximity of the Project’s alignment. The distribution of dolphin sighting during
the reporting month is shown in Figure 2.5.
Encounter
rates of Chinese White Dolphins are deduced from the survey effort and
on-effort sighting data made under favourable conditions
(Beaufort 3 or below) in August 2016 are shown in Tables 2.12 & 2.13.

One (1) Limit Level exceedance was observed for the
quarterly dolphin monitoring data between June and August 2016, whilst 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 250 m marine mammal exclusion zone
monitoring was undertaken during the period of daytime marine works activities. No sighting of Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) were recorded in August 2016 during the exclusion
zone monitoring.
Passive Acoustic Monitoring (PAM) had
been decommissioned as no marine piling works was carried out outside the
daylight hours since September 2015.
Site
inspections were carried out on a weekly basis to monitor the implementation of
proper environmental pollution control and mitigation measures under the
Contract. In the reporting month, four
(4) site inspections were carried out on 4, 10, 17 and 25 August 2016.
Key
observations during the site inspections are summarized in Table 2.14.
