2.              PROJECT INFORMATION

Background

 

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 district’s 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.

 

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 is:

Ÿ   Contract No. NE/2015/01 and Contract No. NE/2015/02: 7 November 2016.

Ÿ   Contract No. NE/2015/03: 29 May 2017.

Ÿ   Contract No. NE/2017/02: 15 March 2018.

Ÿ   Contract No. NE/2017/01: 23 April 2018.

Ÿ   Contract No. NE/2017/06: 09 November 2018.

Summary of EM&A Requirements

2.10          The EM&A programme requires construction noise monitoring, air quality monitoring, water quality monitoring, environmental site audit, etc.  The EM&A requirements for each parameter are described in the following sections, including:

 

·          All monitoring parameters;

·          Action and Limit levels for all environmental parameters;

·          Event Action Plans;

·          Environmental mitigation measures, as recommended in the Project EIA Report.

 

2.11          The advice on the implementation status of environmental protection and pollution control/mitigation measures is summarized in Section 10 of this report.

 

2.12          This report presents the monitoring results, observations, locations, equipment, period, methodology and QA/QC procedures of the monitoring parameters of the required environmental monitoring works and audit works for the Project in December 2018.
