However, a separate Schedule 2 EIA study for this railway system is conducted to address the associated environmental impacts, taking into account of the latest design.

1.1.3 The EIA Report for Tung Chung Line Extension (the Project) was approved on 12 July 2022 (Register No. AEIAR-235/2022). The Environmental Permet (EP) No. EP-614/2022 was then issued on 9 August 2022.
