(#) 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 and WM2B-C due to shallow water (water depth under 150mm)

(^) 24-hour TSP monitoring at AM1b has been temporary suspended since 27 April 2018 as rented land was demolished and returned to the landlord. Alterative location to replaced AM1b is being seeking by ET for IEC and EPD approval.

 

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, there was 1 Limit Level exceedance recorded for 24-hour TSP monitoring. For water quality monitoring, a total of 11 Limit Level exceedances were recorded under the Project.  The summary of exceedance for the Reporting Period is shown below.

ES.04.   Investigation report for the 24-hour TSP monitoring was completed by ET. Investigation results revealed that the Contractor had properly implemented dust mitigation measures such covering of the stockpile and providing water spraying for dusty haul road and dusty area.  Since Joss paper burning was suspected to be conducted during period of sampling, which affecting the monitoring result, it was conducted that the exceedance was not caused by the works under the Project.

 

ES.05.   Investigation Report for all water quality exceedances was completed by ET.  Investigation results revealed that the Contractor had properly implemented water quality mitigation measures such as well-maintained the wastewater treatment facility and covered the expose area with impervious sheet. It was concluded that the exceedances were related to the unknown source of muddy water contributed from outside the project area and not caused by the works under the Project. Nevertheless, the Contractor was reminded to fully implement the water quality mitigation measure throughout the constriction phase as far as practicable.

 

Environmental Complaint

ES.06.   In this Reporting Period, four (4) documented environmental complaints were received regarding the dust and water quality issues under the EM&A Programme.  The Investigation Reports for the complaints were completed by ET without further comments from IEC. 

 

Notification of Summons and Successful Prosecutions

ES.07.   No environmental summons or successful prosecutions were recorded in the Reporting Period.

 

Reporting Changes

ES.08.   No reporting changes were made in the Reporting Period.

 

Future key issues

ES.09.   During rainy 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, in particular for working areas near Ma Wat Channel and Ping Yuen River.

 

ES.10.   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.11.   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.12.   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.
