Environmental Impact Assessment Ordinance (Cap. 499)
Environmental Impact Assessment Study Brief No. ESB-083/2001
Project Title : Fill Bank at Tseung Kwan O Area 137
Name of Applicant : Civil Engineering Department
1.1 An application (No. ESB-083/2001) for an Environmental Impact Assessment (EIA) study brief under section 5(1) of the Environmental Impact Assessment Ordinance (EIAO) was submitted by the captioned Applicant on 17 August 2001 with a project profile (No. PP-140/2001) (the Project Profile).
1.2 The purpose of the Project is to establish and operate a fill bank at Tseung Kwan O Area 137 (Figure 1) for temporary stockpiling of public fill to supplement the projected shortfall in the overall territory-wide public fill capacity, particularly between 2002 and 2005. When surplus public fill capacity is available in the territory, the stockpile in TKO Area 137 will be removed and delivered, mainly by barges, to the public fill areas with surplus capacities.
1.3 A Construction and Demolition Material Sorting Facility (C&DMSF) will be established within the fill bank for sorting mixed construction and demolition (C&D) materials and reducing the over-sized materials contained in C&D materials.
1.4 Construction and demolition (C&D) materials are a mixture of inert materials (e.g. soil, rocks and broken concrete) and wastes arising from construction activities. Local construction industry annually produces about 14 million tonnes of C&D materials. At the moment, most of the inert materials (also known as public fill) are reused at reclamation projects, which hitherto have been the major outlet for these materials. It is anticipated that by mid-2002 most of the approved reclamation projects will no longer be able to absorb further public fill.
1.5 The Project site is located in Tseung Kwan O Area 137 covering an area of approximately 104 hectares. To the east of the Project site is Clear Water Bay Country Park and to its north are the SENT Landfill and the Tseung Kwan O Industrial Estate (Figure 2). The TVB Broadcast and Production Centre in the Tseung Kwan O Industrial Estate adjoining the northern boundary of the Project site is anticipated to commence operation in early 2003.
1.6 Further north in Tseung Kwan O Area 85 and Area 86 are planned residential developments and schools; in Area 50 two planned schools and Area 51 Oscar By The Sea. To the south across the harbour falling in sight are Island Resort and Fullview Garden in Siu Sai Wan (Figure 2).
1.7 The scope of the Project comprises:
(i) site clearance;
(ii) construction of a temporary storm water system;
(iii) stockpiling of 6 million cubic metres (Mm3) or 10.8 million tonnes of public fill to be delivered by trucks or barges;
(iv) setting up a barging point for transporting the stockpiled public fill by barges; and
(v) constructing and operating a Construction and Demolition Material Sorting Facility (C&DMSF).
1.8 The Project is a designated project by virtue of C.11 of Schedule 2, Part I of the EIAO, which specifies that a public dumping area of not less than 2 ha in size is a designated project.
1.9 Pursuant to section 5(7)(a) of the EIAO, the Director of Environmental Protection (the Director) issues this EIA study brief to the Applicant to carry out an EIA study for the Project.
1.10 The purpose of the EIA study is to provide information on the nature and extent of environmental impacts arising from the establishment, operation and decommissioning of the Project and related activities taking place concurrently. This information will contribute to decisions by the Director on :
(i) the overall acceptability of any adverse environmental consequences that are likely to arise as a result of the Project;
(ii) the conditions and requirements for the detailed design, establishment, operation and decommissioning of the Project to mitigate against adverse environmental consequences wherever practicable; and
(iii) the acceptability of residual impacts after implementation of the proposed mitigation measures.
