ES05            There were two (2) Limit Level exceedances recorded in water quality monitoring. Investigation has been undertaken by ET and investigation result revealed that the Contractor had implemented the water quality mitigation measures, in view of inflow of muddy water was observed from upstream of control station, it was concluded that the exceedances were not related to the works under the Project.

Environmental Complaint

ES06            In this Reporting Period, no environmental complaint was received.

Notification of Summons and Successful Prosecutions

ES07            No environmental summons and prosecutions were recorded in the Reporting Period.

Future Key Issues

ES15            During wet 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.

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.
