Breaches of Environmental
Quality Performance Limits (AL levels)
iii. No Action and
Limit Level exceedance was recorded for air quality monitoring and construction
noise monitoring in the reporting month.
iv. No Action and
Limit Level exceedance was recorded for water quality monitoring in the
reporting month.
v. No Action / Limit exceedance was recorded for noise levels at stations
(NMS1 and NMS2) in close proximity to the two active
ardeid night roosts (ANR1 and ANR2) observed within the Survey Area during the
reporting month.
vi.
No Action / Limit exceedance for the ecological monitoring of birds in
the reporting month.
vii. No corrective
actions were required according to the Event and Action Plans for the
Monitoring Parameters.
Land Contamination
viii. Regular site
inspection was carried out to ensure the recommended mitigation measures are
properly implemented. The signed final Contamination Assessment Report (CAR)
for “Main Storeroom & Workshops”, “Mechanical Workshop”, “Waste Storage
Area” and “SAS
Thickener House-1” were submitted to EPD respectively
on 1st November 2021, 23rd November 2021, 29th
April 2022 and 6th July 2022. No
contaminated soil and ground water was found within the
Main Storeroom & Workshop, Mechanical Workshop, Waste Storage Area and SAS
Thickener House-1, and no remedial action is required for both locations.
