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 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. 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 Seventh Annual EM&A Report presenting the EM&A works carried out during the period from 1 November 2019 to 16 March 2020 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, there were no major works undertaken in the reporting period.

Introduction
1.1
Background
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.
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 TM-CLKL (“the Contract”) 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 Hong Kong Ltd. was employed by 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. The impact monitoring phase of the EM&A programme, including air quality, noise, water quality and marine ecological monitoring as well environmental site inspections, commenced on 31 October 2013.
The general layout plan of the Contract components is presented in Figures 1.1 & 1.2a to l.

2.3.3
Results and Observations
In this reporting period, a total of 12 monitoring events were undertaken. Post-construction water quality monitoring was conducted at all designated monitoring stations in the reporting period.

Dolphin Monitoring
2.4.1
Monitoring Requirements
Impact dolphin monitoring is required to be conducted by a qualified dolphin specialist team to evaluate whether there have been any effects on the Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) from the Contract. In order to fulfil the EM&A requirements and make good use of available resources, the impact line transect dolphin monitoring data collected by HyD’s Contract No. HY/2012/08 TMCLKL Northern Connection Sub-Sea Tunnel Section on monthly basis is adopted to avoid duplicates of survey effort between November 2019 and February 2020.
Responsibility for the implementation of dolphin monitoring was changed from Contract No. HY/2011/03 HZMB HKLR Section between Scenic Hill and HKBCF to Contract No. HY/2012/08 TMCLKL Northern Connection Sub-Sea Tunnel Section since October 2019. The on-going impact line transect dolphin monitoring data collected by HyD’s Contract No. HY/2012/08 TMCLKL Northern Connection Sub-Sea Tunnel Section on the monthly basis is adopted since October 2019.
Termination proposal for construction EM&A programme was approved by EPD on 16 March 2020. The construction phase EM&A programme of the Contract has been terminated since 16 March 2020.

2.4.3
Monitoring Parameter, Frequencies & Duration
The dolphin monitoring covered all transect lines in Northeast Lantau (NEL) and the Northwest Lantau (NWL) survey areas twice per month throughout the entire construction period. The monitoring data were compatible with, and should be made available for, long-term studies of small cetacean ecology in Hong Kong. In order to provide a suitable long-term dataset for comparison, identical methodology and line transects employed in baseline dolphin monitoring was followed in the impact dolphin monitoring.
2.4.4
Monitoring Location
The impact dolphin monitoring was carried out in the NEL and NWL along the line transect as depicted in Figure 2.2. The co-ordinates of all transect lines are shown in Table 2.4 ([2]) below.
