Note:

1.	Noise monitoring commenced on 28 December 2015.
2.	Impact monitoring at station NM2 would only commence after occupation of Tung Chung West Development. In accordance with the Tung Chung New Town Extension EIA Report (Approved on 08 April 2016), the west reclamation area is no longer required, the occupation of Tung Chung West Development will not take place. Thus, impact monitoring at NM2 is not required and will not be commenced.
3.	Noise monitoring at NM3A was suspended since 1 September 2018 due to the commencement of construction works for Tung Chung East Development.
4.	Following the full commissioning of the 3RS, the scope of active construction activities has been significantly reduced. Accordingly, impact monitoring at stations NM3A, NM4, NM5, and NM6 has been discontinued from January 2026 onward.
