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). WM4, WM4-CA and WM4-CB were ceased after last monitoring carried out on 3 May 2021 according to Partial Termination Proposal for Contract 3 approved by EPD on 4 May 2021.

                          (#) Number of air monitoring location changed to 6 since the partial termination proposal approved by EPD on 9 Jul 2020 and 4 May 2021.

                          (~) Number of noise monitoring location changed to 5 since the partial termination proposal approved by EPD on 9 Jul 2020 and 4 May 2021.

 

ES04            Revised termination proposal for Contract 3 was submitted to EPD on 9 April 2021 for approval. The termination proposal covers air quality monitoring station AM9b, noise monitoring stations NM8, NM9 and NM10, Water Quality monitoring stations WM4, WM4-CA and WM4-CB and ET’s site inspection and audit for relevant works area for Contract 3. The proposal was approved by EPD on 4 May 2021 (EPD’s ref.: () in Ax (3) to EP 2/N7/A52 Pt.18). The revised termination proposal for Contract 6 was still under revised by ETL.

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

Reporting Change

ES08            No reporting change was recorded in the Reporting period.

Site Inspection

ES09            The Partial termination proposal for Contract 3 was approved by EPD on 4 May 2021. The site inspection and audit carried out by the RE, ET and IEC and the Contractor for Contract 3 was ceased after last site inspection undertaken on 5 May 2021. No non-compliance was noted during the site inspection. 

ES10            In the Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 6 has been carried out by the RE, ET, IEC and the Contractor on 5, 12, 20 and 27 May 2021.  No non-compliance was noted during the site inspection. 

Future Key Issues

ES11            As wet season is approaching, 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.

ES12            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.

ES13            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.
