Investigation
Reports for water quality exceedances have been conducted by ET accordingly.
Investigation report revealed the Contractor had implemented water quality mitigation
measures such as providing tarpaulin sheet for open slope and surface to minimize muddy runoff. It was concluded that the
exceedance recorded at WM2A(a) on 3, 5, 7 and 18
September 2018 were not caused by the works under the Project. Furthermore, the investigation for
exceedances recorded at WM2A(a) on 24 and 27 September
2018 are still underway by ET and the investigation result will be presented in
next Monthly EM&A Report.

2018 in which IEC joined the site inspection on 27 September
2018. No non-compliance was noted during the site
inspection.
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.
ES18
Since most of construction sites under the Project are
located adjacent to villages, the Contractors should fully
implement air quality mitigation measures to reduce construction dust emission.
