Level exceedances were 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. 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. Two
(2) action level exceedance and two (2) limit level
exceedance for non-aquatic fauna were recorded at T3 & 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. Dry weather throughout the month might also have influenced
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. No
environmental complaint was received in the reporting month.
Notification of Summons and Successful
Prosecutions
15. No
notification of summons or successful prosecutions was received in the
reporting month.
16. 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).
