1                          INtroduction

1.1                    Project Background

1.1.1               The former Kai Tak Airport is located in the south-eastern part of Kowloon Peninsula, comprising the north and south aprons and runway areas extending into the Kowloon Bay. The entire airport site covers a total land area of about 260 hectares, of which the land area other than the north apron is about 96 hectares.

1.1.2               Kai Tak Airport was the international airport of Hong Kong, which had come into operation since 1920s.  The operation of the former Kai Tak Airport was ceased and replaced by the new airport at Check Lap Kok in July 1998.  After closure, the disused airport site has been occupied by various temporary uses such as public fill banks, bus depots, car sales exhibitions and recreational grounds.  Nonetheless, most of the original buildings and structures within the airport site have been cleared and the ground contamination identified at the north apron has been decontaminated except the site of the former passenger terminal building and multi-storey carpark building, which remedial works for the ground contamination are near completion.

1.1.3               In 2002, the Chief Executive in Council approved the Kai Tak Outline Zoning Plans (No. S/K19/3 and S/K21/3) to provide the statutory framework to proceed with the South East Kowloon Development at the former Kai Tak Airport.  However, following the judgment of the Court of Final Appeal in January 2004 regarding the Harbour reclamation, the originally proposed development which involved reclamation has to be reviewed.  The Kai Tak Planning Review (KTPR) has resulted a Preliminary Outline Development Plan (PODP) for Kai Tak in October 2006 as shown in Drawing 1.1. 

1.1.4               In order to make available the remaining former Kai Tak Airport site for the Kai Tak Development (KTD), the Decommissioning of the Former Kai Tak Airport Other than the North Apron (hereinafter called ‘the Project’) is proposed to demolish remaining existing structures / buildings and remove abandoned facilities of the former Kai Tak Airport within the Project boundary; identify and clean up contaminated areas associated with the previous airport operation within the Project boundary; and implement appropriate mitigation measures to ensure the site would be safe and free of hazards for the planned future use.  The general layout of the Project site is shown in Drawing 1.2.

1.1.5               The Project is a Designated Project under Item 1 of Part II Schedule 2 of the Environmental Impact Assessment Ordinance (EIAO): “Decommissioning of airports, including fueling and fuel storage, the aircraft maintenance and repair facilities”.  An Environmental Impact Assessment (EIA) Study for the Project has been undertaken in accordance with the EIA Study Brief (No. ESB-160/2006) and the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM).

1.2                    Project Scope and Programme

1.2.1               The scope of existing structures and buildings for decommissioning as well as the related construction activities for this Project is summarized in Table 1.1 below and location of the decommissioning / decontamination is depicted in Drawing 1.3.

Table 1.1                        Summary of Construction Activities 

Decommissioning Works

Decontamination Works

ll    Removal of an existing fuel hydrant system buried in south apron of the former Kai Tak Airport;


ll    Removal of underground fuel tanks near the ex-Government Flying Service (ex-GFS) building and fuel supply system (including refuelling pits and underground pipelines) in the ex-GFS apron area; and


ll    Demolition of the fuel dolphin structure down to 1m below the existing seabed level. The abandoned fuel pipelines would be left in place and, if necessary, grouting it with concrete.

ll    Decontamination works, including excavation and the necessary treatment of the contaminated soil identified at the south apron, the narrow strip of the north apron near the Kai Tak Tunnel and the ex-Government Flying Service (ex-GFS) apron area


1.2.2               The construction activities listed in Table 1.1 above would commence in early 2008 and be completed not earlier than late 2009.  A summary of the tentative project programme is provided in Table 2.2 below.  Given the comparatively minor in scale of the decommissioning and decontamination works in such a large area and the pressing need to proceed with the permanent development, construction in some areas where ground contamination is found, would immediately commence after the site clean up is confirmed.  Elsewhere ground contamination is not found, the construction would proceed upon the approval of the EIA report in concurrent with the decontamination works as long as they are demonstrated to be environmentally compatible and acceptable.  Based on the latest information, the cruise terminal construction and its associated advance works will be carried out while the decommissioning / decontamination works at other parts of the Project area are underway.

1.3                    Purpose of the Manual

1.3.1               The purpose of this Environmental Monitoring and Audit (EM&A) Manual is to guide the set up of an EM&A programme to ensure compliance with the EIA study recommendations, to assess the effectiveness of the recommended mitigation measures and to identify any further need for additional mitigation measures or remedial action.  This Manual outlines the monitoring and audit programme for the proposed Project.  It aims to provide systematic procedures for monitoring, auditing and minimising environmental impacts associated with Project activities.

1.3.2               Hong Kong environmental regulations and the Hong Kong Planning Standards and Guidelines have served as environmental standards and guidelines in the preparation of this Manual.  In addition, the EM&A Manual has been prepared in accordance with the requirements stipulated in Annex 21 of the EIAO-TM.

1.3.3               This Manual contains the following information:

·            Responsibilities of the Contractor, the Engineer or Engineer’s Representative (ER), Environmental Team (ET) and Independent Environmental Checker (IEC) with respect to the environmental monitoring and audit requirements during the course of the Project;

·            Project organisation;

·            The basis for, and description of the broad approach underlying the EM&A programme;

·            Requirements with respect to the construction programme schedule and the necessary environmental monitoring and audit programme to track the varying environmental impact;

·            Details of the methodologies to be adopted, including all field laboratories and analytical procedures, and details on quality assurance and quality control programme;

·            The rationale on which the environmental monitoring data will be evaluated and interpreted;

·            Definition of Action and Limit Levels;

·            Establishment of Event and Action Plans;
