1 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 Environ 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.

2.4.6 Monitoring Schedule for the Reporting Month

Dolphin monitoring was carried out on 1, 8, 17 and 24 November 2017 (Appendix F).

2.4.7 Results and Observations

A total of 261.46 km of survey effort was collected, with 100% 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 November 2017. Among the two areas, 94.40 km and 167.06 km of survey effort were collected from NEL and NWL survey areas, respectively. The total survey effort conducted on primary and secondary lines were 190.80 km and 70.66 km, respectively. The survey efforts are summarized in Appendix K.

Six (6) groups of 31 Chinese White Dolphins were sighted during the two sets of monitoring surveys in November 2017. All dolphin sightings were made in NWL, while none was sighted in NEL. During the surveys in November 2017, all sightings were made during on-effort search, while five of the six on-effort sightings were made on primary lines. None of the dolphin groups was associated with operating fishing vessel and was not 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 November 2017 are shown in Tables 2.12 & 2.13.
