1. INTRODUCTION

Background

1.1 The Kai Tak Development (KTD) is located in the south-eastern part of Kowloon Peninsula, comprising the apron and runway areas of the former Kai Tak Airport and existing waterfront areas at To Kwa Wan, Ma Tau Kok, Kowloon Bay, Kwun Tong and Cha Kwo Ling. It covers a land area of about 328 hectares. The Project also covers Kowloon Bay and Kwun Tong Typhoon Shelter and the adjacent water bodies. The general layout of the Project is shown in Figure 1.

1.2 Civil Engineering and Development Department (CEDD) had completed an Environmental Impact Assessment (EIA) study for KTD under Agreement No. CE 35/2006(CE) Kai Tak Development Engineering Study cum Design and Construction of Advance Works ¡V Investigation, Design and Construction (hereafter called ¡§Schedule 3 EIA Report¡¨). The Schedule 3 EIA Report was approved under Environmental Impact Assessment Ordinance (EIAO) in March 2009.

1.3 As recommended in the Schedule 3 EIA Report, EM&A programme shall be required for different phases of the KTD as a whole. In March 2017, Castco Testing Centre Limited (CTCL) was commissioned by CEDD to undertake the Environmental Monitoring and Audit (EM&A) works for KTD. Under the Contract, Environmental Team (ET) shall oversee all the environmental issues within the Kai Tak Development (KTD).

1.4 CTCL was commissioned by CEDD to undertake the Environmental Monitoring and Audit (EM&A) works for KTD Contract No. KLN/2016/09 starting from 3 March 2017. This is the 26^th Monthly EM&A report summarizing the EM&A works for the Project in April 2019.

Construction Activities undertaken during the Reporting Month

1.7 There are several works contracts undertaken within KTD during the reporting month. In order to collect relevant environmental information from the work contracts and incorporate into this monthly monitoring report, a survey form for monthly environmental performance records was sent to all work contracts/tenants within KTD on 31 March 2019. The survey form shall be returned by 5^th of each month to provide the environmental monthly information of respective work contracts within KTD.

1.8 Based on the returned survey form from work contracts and site observation for short term tenancy (STT) / temporary government land allocation (TGLA) during the weekly site inspection, the major site activities undertaken within Kai Tak Development (KTD) in the reporting month are summarized in Table 1.2.
