proposal for Contract 3 was approved by EPD on 4 May 2021 (EPD¡¦s ref.: () in Ax
(3) to EP 2/N7/A52 Pt.18). Therefore, air quality monitoring stations AM1c, AM8
& AM9b, noise monitoring stations NM1, NM7, NM8, NM9 & NM10 and water
quality monitoring stations WM4, WM4-CA & WM4-CB and ET¡¦s site inspection
and audit for relevant works area for Contracts 2, 3, 4, 7 and SS C505 was
