1. This is the 50th Environmental Monitoring and Audit (EM&A) Report prepared by Cinotech Consultants Limited for the Agreement No. CE 59/2015 (EP) Environmental Team for Tseung Kwan O Lam Tin Tunnel Design and Construction (hereinafter called the Project). This report documents the findings of EM&A Works conducted in December 2020.
2. During the reporting month, the following works contracts were undertaken:
· Contract No. NE/2015/01 Tseung Kwan O Lam Tin Tunnel Main Tunnel and Associated Works;
· Contract No. NE/2015/02 Tseung Kwan O Lam Tin Tunnel Road P2 and Associated Works;
· Contract No. NE/2015/03 Tseung Kwan O Lam Tin Tunnel Northern Footbridge;
· Contract No. NE/2017/01 Tseung Kwan O Lam Tin Tunnel Tseung Kwan O Interchange and Associated Works
· Contract No. NE/2017/02 Tseung Kwan O Lam Tin Tunnel Road P2/D4 and Associated Works.

· Contract No. NE/2017/07 Cross Bay Link, Tseung Kwan O Main Bridge and Associated Works.
3.
Environmental
monitoring for the Project was performed in accordance with the EM&A Manual
and the monitoring results were checked and reviewed. Site Inspections/Audits
were conducted once per week. The implementation of the environmental
mitigation measures, Event Action Plans and environmental complaint handling
procedures were also checked.
4. Summary of the non-compliance (exceedance) in the reporting month for the Project is tabulated in Table I.

Water
Quality Monitoring
9.
Groundwater
quality monitoring had been suspended since October 2019 upon the agreement by
EPD. Further details should be
founded at Section 5.1.
10. All marine water quality monitoring was conducted as
scheduled in the reporting month. There were forty-one (41) Action Level and one hundred and
twenty-three (123) Limit Level exceedances in
Monitoring Stations (M) during marine water quality monitoring. During this reporting month, no sand plume was
observed during the water quality monitoring and site audits, therefore there
is no direct evidence that the recent exceedances were due to the construction
works of the Project. Details of this investigation are presented in Section 5. Daily silt curtain
inspection and weekly diving inspection have been carried out by contractor,
the record, as reviewed by the site auditors, indicated that silt curtains were
found in good conditions.
11. Construction phase daily piezometer monitoring by the Contractor commenced in June 2018. It has switched to monthly basis since 3 October 2018 as the construction activity was 120m away from the piezometer gate. No monitoring was conducted in the reporting month.
Ecological
Monitoring
12. Post-translation coral monitoring survey shall be conducted once every 3 months for a period of 12 months after completion of coral translocation. The post-translocation coral monitoring surveys were completed in November 2017.
Monitoring
on Cultural Heritage
13. Monitoring of impacts on Cultural Heritage at Cha Kwo Ling Tin Hau Temple commenced in May 2017. No Alert, Alarm and Action (AAA) Level exceedance was recorded in the reporting month.
Landscape
and Visual Monitoring and Audit
14. The implementation of landscape and visual mitigation measures was checked during the environmental site inspections. Recommended follow-up actions have been discharged by the Contractor. Details of the audit findings and implementation status are presented in Section 10.
Landfill
Gas Monitoring
15. Monitoring of landfill gases commenced in December 2016 and were carried out by the Contractor at excavation location, Portion III. No Limit Level exceedance was recorded.
Environmental Site Inspection
16. Joint weekly site inspections were conducted by representatives of the Contractor, Engineer and Environmental Team. The representative of the IEC joined the site inspection for NE/2015/01, NE/2015/02, NE/2017/01, NE/2017/02 and NE/2017/06 on 24 December 2020 respectively. Details of the audit findings and implementation status are presented in Section 10.
17. The representative of the IEC did not join the joint weekly site inspection of NE/2015/01 due to the pandemic crisis.
Waste
Management
18. Wastes generated from this Project include inert construction and demolition (C&D) materials, non-inert C&D materials and marine sediment. Details of waste management data is presented in Section 11 and Appendix P.

Section 14: Conclusions and Recommendation
2.1 In 2002, Civil Engineering and Development Department (CEDD) commissioned an integrated planning and engineering study under Agreement No. CE 87/2001 (CE) Further Development of Tseung Kwan O Feasibility Study (the TKO Study) to formulate a comprehensive plan for further development of TKO New Town. It recommended to further develop TKO to house a total population of 450,000 besides the districts continuous commercial and industrial developments.
2.2 At present, the Tseung Kwan O Tunnel is the main connection between Tseung Kwan O (TKO) and other areas in the territory. To cope with the anticipated transport need, the TKO Study recommended the provision of Tseung Kwan O Lam Tin Tunnel (TKO-LTT) (hereinafter referred to as the Project) and Cross Bay Link (CBL) to meet the long-term traffic demand between TKO and the external areas. The site layout plan for the Project is shown in Figure 1. CBL was also entrusted with part of the marine viaducts near Tseung Kwan O Interchange since the commencement of the CBL project the December 2018.
2.3 The Environmental Impact Assessment (EIA) Report for the TKO-LTT project was approved under the Environmental Impact Assessment Ordinance (EIAO) in July 2013. The corresponding Environmental Permit (EP) was issued in August 2013 (EP no.: EP-458/2013). Variations to the EP was applied and the latest EP (EP no.: EP-458/2013/C) was issued by the Director of Environmental Protection (DEP) in January 2017.
2.4 The commencement dates of construction of this Project are:
Contract No. NE/2015/01 and Contract No. NE/2015/02: 7 November 2016.
Contract No. NE/2015/03: 29 May 2017.
Contract No. NE/2017/02: 15 March 2018.
Contract No. NE/2017/01: 23 May 2018.
Contract No. NE/2017/06: 09 November 2018.
