(#) IEC only joined inspection for Contract SS C505 once per month.

(*) During the whole reporting period, water sampling was unable to carry out at WM2B, WM2B-C and WM3-C due to shallow water (water depth under 150mm)

(^)In response to the Government’s appeal on special work arrangement and minimize the spread of the novel coronavirus, all the Resident Site Staff (RSS) of the project would work at home from 29 January 2020 to 2 February 2020. Moreover, the Contractors were instructed to restrict site works and there would not have major construction activities/continue site closure during the concerned period. Due to the abovementioned arrangement, the environmental site inspection by Environmental Team in this week was affected and has to be cancelled.

 

Breaches of Action/Limit levels

ES.03.   In the Reporting Period, no noise exceedance and valid noise complaint was registered for construction noise.  For air quality, no exceedance recorded for 1-hour and 24-hour TSP monitoring. For water quality monitoring, no exceedance recorded under the Project.  The summary of exceedance for the Reporting Period is shown below.

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

 

Reporting Changes

ES.06.   As advised by the Contractor, construction of WCA was commenced on 11 November 2019.  According to the approved HCMP and further clarified by the RE and Contractor, site inspection is required during construction of wetland.

 

Future key issues

ES.07.   During the dry season, the Contractors should fully implement the air quality mitigation measures to reduce construction dust emission, particularly in the construction area which located adjacent to villages.

 

ES.08.   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.
