Air Quality

5.      All construction air quality monitoring was conducted as scheduled in the reporting month. No Action/Limit Level exceedance was recorded.

Construction Noise

6.      All construction noise monitoring was conducted as scheduled in the reporting month.  One (1) Action Level exceedance was recorded. No Limit Level exceedance was recorded.


 

Water Quality

7.      All additional water quality monitoring was conducted as scheduled in the reporting month. Four (4) Limit Level for Suspended Solid, and Four (4) Limit Level for turbidity of impact water quality monitoring were recorded. No construction of channel for alternation of natural streams was carried out in the reporting month. Therefore, no water quality monitoring was conducted according to the Updated EM&A Manual and Baseline Water Quality Monitoring Report (KTN & FLN NDA). Relevant details are given in Section 5.

Land Contamination

8.      All ambient arsenic monitoring was conducted as scheduled in the reporting month. No Action/Limit Level exceedance was recorded.

Landfill Gas Monitoring

9.      Monitoring of landfill gas in the reporting month was carried out by the Contractor under ND/2019/01 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 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.

12.  Five (5) action level exceedance and four (4) limit level exceedance for non-aquatic fauna were recorded at T1, T3, T4 & T6. The exceedance were considered non-project related. Poor weather condition of during monitoring period for T6 on 11th March with 11.7 mm total rainfall might have affected butterfly and odonate occurrence at T6. Whilst limited rainfall throughout the reporting month might also have influenced availability of microhabitat for odonates and herpetofauna, and thus number of species of odonates recorded. In addition, necessary Ecological mitigation measure were provided by all nearby project-related sites. No evidence to suggest that the exceedance was related to project activities.

13.  The ecological monitoring result in the Reporting Month is shown in Appendix L.

Complaint Log

14.  Two (2) environmental complaints were received in the reporting month. The complaint regarding construction noise is for ND/2019/04, which was referred by EPD on 4 Mar 2024 for the complaint case received by EPD on 3 Mar 2024. The other complaint case associated with construction dust is also for ND/2019/04, which was referred by EPD on 19 Mar 2024 for the complaint case received by EPD on 17 Mar 2024.

Notification of Summons and Successful Prosecutions

15.  No notification of summons or successful prosecutions was received in the reporting month.
