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. Passive Acoustic Monitoring (PAM) was implemented when the marine works were 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 December 2014 during the exclusion zone monitoring.

Future Key Issues
Potential environmental impacts arising from the above upcoming construction activities in the next reporting month of January 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 – 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.

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 three (3) groups of five (5) Chinese
White Dolphins were sighted during the two sets of monitoring surveys in
December 2014 (Appendix K). All
sightings were made in NWL during the two sets of surveys in December 2014,
while no dolphin was sighted at all in NEL in this reporting month. All three (3)
sightings were made on primary lines during on-effort search, and none of the
dolphin groups was associated with operating fishing vessel. No sighting was
made in the proximity of the Project’s alignment. The distribution of dolphin
sightings 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 December 2014 are shown in Tables 2.12 and 2.13.

The average group size of Chinese White Dolphins in December 2014 was 1.67 individuals per group, which was much lower than the ones in previous months of dolphin monitoring. All three (3) dolphin groups were composed of only one to three (1-3) animals during the monitoring period. Detailed results of dolphin monitoring in this reporting month are presented in Appendix K.
Daily 250 m marine mammal exclusion zone monitoring was undertaken during the period of marine works activities being undertaken. Passive Acoustic Monitoring (PAM) was implemented when the marine works were carried out outside the daylight hours in this reporting month. No sighting of Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) were recorded in December 2014 during the exclusion zone monitoring.

Potential environmental impacts arising from the above upcoming construction activities in the next reporting month of January 2015 are mainly associated with dust, noise, marine water quality, marine ecology and waste management issues.
This Fourteenth Monthly EM&A Report presents the findings of the EM&A activities undertaken during the period from 1 to 31 December 2014, in accordance with the Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/C).
A total three (3) groups of five (5) Chinese White Dolphins were sighted during the two sets of monitoring surveys in December 2014. All sightings were made in NWL during the two sets of surveys in December 2014, while no dolphin was sighted at all in NEL in this month. All three (3) sightings were made on primary lines during on-effort search, and none of the dolphin groups was associated with operating fishing vessel. 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 were 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.
