Environmental Complaint

ES.04.   In this Reporting Period, nine (9) documented environmental complaints were received and lodged.  Follow up actions have been undertaking by the Contractor to resolve the deficiencies. The investigation reports conducted by the ET were all completed and submitted to all relevant parties.  In brief, all complaints were unlikely due to the project.  However, the Contractor was reminded to fully implement the recommended mitigation measures as per the EM&A Manual.

 

Notification of Summons and Successful Prosecutions

ES.05.   No environmental summons or successful prosecutions were recorded in the Reporting Period.  

 

Reporting Changes

ES.06.   EPD has approved the revised EM&A Programme on 29th March 2016. If the measured water depth of the monitoring station is lower than 150 mm, alternative location based on the criteria will be selected to perform water monitoring in accordance with the updated EM&A Programme (Rev. 05) (Section 4.1.4)

 

Future key issues

ES.07.   In upcoming 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 or public area would be the key issue.  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.  Moreover, 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.08.   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.09.   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.
