1          Introduction

1.1          Background

To connect the Hong Kong-Zhuhai-Macao Bridge (HZMB) Hong Kong Boundary Crossing Facilities (HKBCF) with the Hong Kong International Airport (HKIA), roads including an elevated bridge structure (hereinafter referred to as “the HKBCF Viaduct/Roads”) were proposed as part of the HKBCF project, as described in Section 4.5 of the approved Environmental Impact Assessment (EIA) report of the HKBCF project. The HKBCF Viaduct/Roads are located partly within the boundary of the Airport Island near Terminal 2 (T2) and partly within the boundary of the land corridor between HKBCF and the Airport Island, i.e., partly within the HKBCF boundary.

Under the HKBCF project, the arrangements for the planning of the construction of the HKBCF Viaduct/Roads were formulated based on the scenario with the existing two-runway system (2RS) at the HKIA. The portion of the HKBCF Viaduct/Roads falling within the boundary of the land corridor between HKBCF and HKIA were originally planned to be constructed by Highways Department (HyD) of the Government of the Hong Kong Special Administrative Region (HKSARG) as part of the HKBCF project.

With the planned expansion of HKIA into a three-runway system (3RS), a revised layout of the HKBCF Viaduct/Roads (the revised layout is hereinafter referred to as the proposed “HKIA-HKBCF Road Connection”) was formulated as part of the P282 Terminal 2 Expansion Design Consultancy of Airport Authority Hong Kong (AAHK). The proposed HKIA-HKBCF Road Connection has taken the design of the 3RS road network designed around the expanded T2 building into account. In addition to preparing the detailed design, it was also considered that the proposed HKIA-HKBCF Road Connection within the HKBCF boundary would be constructed by AAHK instead of HyD along with the 3RS road network planned within the Airport Island. Upon completion of the construction works, the new HKIA-HKBCF Road Connection outside the Airport Island would be handed over to HyD for future operation and maintenance.

The EIA for the HKBCF project, which covered the HKBCF Viaduct/Roads as a Designated Project (DP) based on the requirements set out in Item A.8. (i.e., a road bridge more than 100 m in length between abutments) in Part 1 of Schedule 2 to the Environmental Impact Assessment Ordinance (EIAO) (Cap. 499), was completed and approved (EIA Register No.: AEIAR-145/2009) and an Environmental Permit (EP) (EP No.: EP-353/2009) was granted under the EIAO to HyD.

On the other hand, the 3RS EIA had subsequently commenced and completed (EIA Register No.: AEIAR-185/2014) by AAHK, and it has already taken the layout of the proposed HKIA-HKBCF Road Connection into account and has assessed the relevant cumulative environmental impacts. The planned change in implementation agent from HyD to AAHK for the construction of the proposed HKIA-HKBCF Road Connection outside the Airport Island would, involves a transfer of corresponding responsibilities under the HKBCF EP from HyD to AAHK. To this end, an Environmental Review Report (ERR) was prepared and submitted to Environmental Protection Department (EPD) in November 2018 which concluded that the change of implementation agent from HyD to AAHK for the construction of HKIA-HKBCF Road Connection would not result in any exceedance or violation of the environmental performance requirements set out in the approved HKBCF and 3RS EIAs and the mitigation measures identified in these EIAs remained relevant and valid. A Further Environmental Permit (EP No. FEP-01/353/2009/K) for the construction of the HKIA-HKBCF Road Connection (hereinafter referred to as “the Project”) was granted to AAHK in December 2018 in accordance with Section 12 of EIAO. Afterwards, an Environmental Monitoring and Audit Manual for HZMB HKBCF – The Road Connection between HKBCF and the Airport, Chek Lap Kok (the EM&A Manual) has been prepared to include appropriate environmental monitoring and audit (EM&A) requirements in accordance with the information and recommendations described in the EIA Report and by taking into account the specific site conditions of the Project under the FEP. 

The Project consists of the construction of a road bridge more than 100 m in length between abutments connecting between HKBCF and the HKIA which is part of the work for HZMB-HKBCF. Location of the Project is shown in Figure 1.1.

Site clearance and preparation works of the Project started in August 2021, and the construction works commenced on 4 October 2021. The summary of construction works programme can be referred to Section 1.4.

The monthly summary of waste flow table is presented in Appendix D. There was no non-compliance of the WMP, statutory and contractual requirements during the reporting period.

Material excavated from bored piles foundation works was regarded as potential marine sediment and was temporary stored on site and treated as backfilling materials for reuse in other projects. Based on the contractor's additional information which was reviewed and agreed by relevant parties including AAHK, ET and IEC, the material excavated was not classified as marine sediment.  The excavated material would be handled as inert C&D material according to the WMP, reused onsite or offsite for backfilling so that the need for offsite disposal is minimised as far as practicable.
