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. No Action/Limit Level exceedance was recorded.

Water Quality

7. All additional water quality monitoring was conducted as scheduled in the reporting month. No Action/Limit Level Exceedance was 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. Built heritage monitoring was carried out in the reporting month by the Contractor under ND/2019/05 for surveyed cultural heritage. No Limit Level exceedance was recorded.

Ecological Monitoring

11. All ecological monitoring was conducted as scheduled in the reporting month.

12. One (1) limit level exceedance for fish monitoring was recorded at MS_04, MS_06 & MS_07. The exceedances were considered non-project related. No project-related construction site activity was observed directly nearby. No exceedance of water quality was recorded in reporting month. Besides the environmental condition, no exceedance in number of native species of aquatic macroinvertebrates was recorded at the same location, whilst 4 non-native species of fishes were recorded in the same locations, thus it seems that the exceedance was unlikely due to project-related construction works.

13. Six (6) action level exceedance and four (4) limit level exceedance for non-aquatic fauna were recorded at T3, T4 & T5. 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. 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.

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

Complaint Log

15. No environmental complaint was received in the reporting month.

Notification of Summons and Successful Prosecutions

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

Reporting Changes

17. This report has been prepared in compliance with the reporting requirements for the subsequent monthly EM&A Report as required by the ¡§Updated Environmental Monitoring and Audit Manual for Advance and First Stage Works of Kwu Tung North and Fanling North New Development Areas¡¨ (Updated EM&A Manual).
