ES.04.   Investigation Report for all water quality exceedances was completed by ET. A total of six (6) Limit Level exceedances were recorded during water quality monitoring. The investigation report for exceedance recorded at WM2A(a) on 29 and 31 May 2019 and 26 June 2019 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. The investigation report for exceedance recorded at WM3x on 31 July 2019 revealed that the exceedances were related to the rainstorm and unlikely caused by the works under Contract 2. Nevertheless, the Contractor was reminded to fully implement the water quality mitigation measure throughout the constriction phase as far as practicable.

 

Environmental Complaint

ES.05.   In this Reporting Period, no environmental complaint was received.

 

Notification of Summons and Successful Prosecutions

ES.06.   No environmental summons or successful prosecutions were recorded in the Reporting Period.

 

Reporting Changes

ES.07.   The project (except for the BCP building complex) was commenced on 26 May 2019.  In view of the partial commencement of operation to be considered as the same as the commencement of operation for the entire project, all relevant requirements as stipulated in the EP and the approved EIA report (including the EM&A Manual) for the commencement of operation of the Project shall be strictly complied with.  The implementation status of mitigation measures for operation phase in the Reporting Period will be presented in the Report.

 

Future key issues

ES.08.   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.

 

ES.09.   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.

 

ES.10.   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.

 

ES.11.   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.
