Remark:

                          (*) Water sampling was unable to carry out at WM2B and WM2B-C in the Reporting Period due to shallow water. Besides, WM3-C was also unable to carry out in the Reporting Period due to shallow water.  (Water depth under 150mm).

                          (#) Number of air monitoring location changed to 7 since the partial termination proposal approved by EPD on 9 Jul 2020.

                          (~) Number of noise monitoring location changed to 8 since the partial termination proposal approved by EPD on 9 Jul 2020.

 

ES04            As the major construction work under Contract 3 and Contract 6 were substantially completed. In view of insignificant environmental impacts of the remaining outstanding construction works of Contracts 3 and 6, ¡§proposal for termination of the Construction Phase Environmental Monitoring & Audit (EM&A) Programme for the remaining Contract 3 and Contract 6 of the Project¡¨ which certified by ETL and verified by IEC, was submitted to Environmental Protection Department (EPD) on 18 November 2020. EPD issued comments on 6 January 2021 and the revised proposal has been subsequently prepared and certified by ETL and verified by IEC. The revised proposal was re-submitted by AECOM to EPD with written agreement/confirmation obtained from CEDD on 5 February 2021.
