Investigation
Reports for water quality exceedances have been conducted by ET
accordingly. Investigation results
revealed that the Contractor had properly implemented water quality mitigation
measures such as well-maintained the wastewater treatment facility and covered
the expose area with impervious sheet.
It was concluded that all exceedances recorded at WM3x and the
exceedances recorded at WM1 on 10 August 2018 were not caused by the works
under the Project. However, there
were 5 AL/ LL exceedances recorded at WM4 concluded as partially related to the
work under Contract 2 while the Contractor has promptly rectified the
deficiency. Furthermore, the
investigation for exceedances recorded at WM2A(a) during 22 to 31 August 2018
and recorded at WM1 on 30 August 2018 are still underway by ET and the investigation
result will be presented in next Monthly EM&A Report.

Future Key Issues
ES15
During rainy season, preventive measures for muddy
water or other water pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma
Wat Channel, Ping Yuen River, Kwan Tei River or public area should
be properly maintained. The
Contractors should paid special attention
on water quality mitigation measures and fully implement according ISEMM of the
EM&A Manual, in particular for working areas near Ma Wat Channel and Ping
Yuen River.
ES16
In addition, all effluent
discharge shall be ensure to fulfill Technical Memorandum of Effluent
Discharged into Drainage and Sewerage Systems, inland and Coastal Waters
criteria or discharge permits stipulation.
ES17
Construction noise would
be a key environmental issue during construction work of the Project. Noise mitigation measures such as using quiet plants should be implemented in
accordance with the EM&A requirement.
