Three Action Level
exceedance were recorded for water quality in the reporting month. The
exceedance were recorded at M1 on 22 May 2021 and recorded at M3 on 27 and 29
May 2021. Six Limit Level exceedance were recorded for water quality in
the reporting month. The exceedance were recorded at M1 and M3 on 25 and 27 May
2021. It was found that these exceedances were not project-related.
vi.
Two exceedances in
Action Level were recorded for the ecological monitoring of birds on 17 May
2021, in which significant declines were found in species diversity of all
avifauna species in the community; and species diversity of species of
conservation importance only. However, the exceedances were not
project-related.
