Future Key Issues
Potential environmental impacts arising from the upcoming construction activities are mainly associated with dust, waste management and landfill gas monitoring 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 (VEP) (EP-354/2009/A) was issued on 8 December 2010. Subsequent applications for variation of environmental permits (VEPs), 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.

In response to the site audit findings, the Contractors carried out all corrective actions.
A summary of the Implementation Schedule of Environmental Mitigation Measures (EMIS) is presented in Appendix B. The necessary mitigation measures relevant to this Contract were implemented properly.
Twenty-five (25) Action Level and two (2) Limit Level exceedances of 1-hour TSP and two (2) Action Level exceedance of 24-hour TSP were recorded by the Environmental Team of Contract No. HY/2012/08 during the reporting period. The exceedances were considered not related to this Contract upon further investigation and the investigation reports were presented in Appendix G of the Third to Seventh and Ninth Monthly EM&A Reports and Appendix J of the Eighth, Tenth and Twelfth Monthly EM&A Reports. No action is required to be undertaken in accordance with the Event Action Plan as presented in Appendix D.
No exceedance of Action and Limit Levels for methane, oxygen and carbon dioxide was recorded landfill gas hazard monitoring in the reporting period.
Cumulative statistics are provided in Appendix G.
The Environmental Complaint Handling Procedure is provided in Figure 2.2.
There were one (1) complaint received from EPD. Upon investigation, there were no adequate evidences to conclude that the complaint cases were related to this Contract and the investigation report was presented in Appendix J of the Twelfth EM&A Report.
No notification of summons or successful prosecution was received in the reporting period.
The EM&A results in the reporting period are compared to the predictions from EIA Report and baseline monitoring result for the sake of reviewing the validity of EIA predictions.
Land based construction activities were conducted during the reporting period. At the same time, monitoring on air quality, landfill gas hazard monitoring and waste were undertaken per plan.
Based on the findings presented in TM-CLKL EIA study, the major sources of dust nuisance arising from the Northern Connection are related to excavation, wind erosion from reclaimed areas, open sites and stockpiling areas. Therefore, during these construction activities, the TSP monitoring frequency will be increased at all air quality monitoring stations such that any deteriorating air quality can be readily detected and timely action taken to rectify the situation. Comparison of EIA prediction, average baseline monitoring and average impact monitoring results of TSP is presented in Table 3.1.
Results of air quality monitoring were adopted from the published EM&A data of Contract No. HY/2012/08 Tuen Mun-Chek Lap Kok Link – Northern Connection Sub-sea Tunnel Section ([5]).
