at excavation location Portion 6b. No Limit Level exceedance was recorded.
Built Heritage Monitoring
10. No Built
heritage monitoring was carried out in the reporting month due to no works
causing vibration for surveyed cultural heritage at all. No Limit Level
exceedance was recorded.
Ecological Monitoring
11. All
ecological monitoring was conducted as scheduled in the reporting month. Four (4)
action level exceedance and four (4) limit level
exceedance for non-aquatic fauna were recorded at T3 and T6. The exceedance were
considered non-project related, as large proportion of vegetative habitat along
T3 were observed either removed and tarmacked as haul road by construction
works outside of project, first reported in the Monthly Monitoring Report in
December 2021, as well as adverse weather condition during the monitoring
session saw the non-aquatic fauna result lowered.
The ecological monitoring result in the Reporting Month is shown in Appendix L.
Egretry
Monitoring
12. All
Egretry monitoring was conducted as scheduled in the
reporting month. The monitoring results can refer to the Monthly Egretry Monitoring Report for August 2023.
Complaint Log
13. Two
environmental complaints were received in the reporting month. The complaint
regarding polluting effluent discharged is for ND/2019/05, which was referred
by EPD on 9 August 2023 for the complaint case received by EPD on 4 August 2023.
