Executive Summary

ES.01.   This is the 18th Quarterly EM&A Summary Report for the “Liantang/Heung Yuen Wai Boundary Control Point and Associated Works” under Environmental Permit No. EP-404/2011/D (hereinafter ‘‘the EP’’), covering the period from 1 November 2017 to 31 January 2018 (hereinafter “Reporting Period”).


Environmental Monitoring and Audit Activities

ES.02.   In the Reporting Period, the construction works under Liantang/Heung Yuen Wai Boundary Control Point and Associated Works of the Project included Contract 2, Contract 3, Contract 6, Contract 7 and Contract SS C505.  Environmental monitoring activities under the EM&A programme in the Reporting Period are summarized in the following table.

Note: Extra monitoring day was due to measurement results exceedance

(#) 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)


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 were 6 Action Level exceedances of 24-hour TSP monitoring results recorded. For water quality monitoring, a total of 26 Action/ Limit Level exceedance were recorded.  The summary of exceedance for the Reporting Period is shown below.

Water Quality











      6 numbers of  LL exceedances which recorded on 6, 11, 15 Dec 17 were related to the insufficient mitigation measures for Contract 3.

      Other 20 numbers of exceedances were not project related.

The Contractor was reminded to implement water quality mitigation measures in accordance with ISEMM of the EM&A Manual requirements






ES.04.   Investigation Reports for all 24-hour TSP exceedances were completed by ET which concluded that the exceedances were not project related.  According to the observation during site audit, the Contractor had properly implemented the dust mitigation measures such as provided water spraying on construction area and site haul road regularly.  Moreover, water tanker and road sweeper were deployed the main road on regular basis to suppress fugitive dust and remover dirt and debris on road.  It was considered that the exceedances were likely related to the dust impact from traffic.


ES.05.   Investigation Reports for all water quality exceedances were completed by ET.  The investigation result revealed that the LL exceedances on 6, 11, 15 December 2017 were related to the insufficient water quality mitigation measures for Contract 3 while the other exceedances was not project-related.  As remedial action, the relevant Contractor had enhanced the water quality mitigation measures such as covering the exposed area by tarpaulin sheet to minimize muddy runoff and no project-related exceedance was recorded after the enhancement measures.


Environmental Complaint

ES.06.   In this Reporting Period, four (4) documented environmental complaint was received regarding the air quality and noise issues under the EM&A Programme.  Subsequent joint site inspection was carried out for complaint investigation and investigation reports were submitted by ET after reviewed by IEC.  The IRs revealed that the Contractors have properly implemented the mitigation measures and no breaches of EM&A programme was seen.  Further enhancement measures were included and implemented in response to the complaint.  


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 dry season, special attention should be paid on the potential construction dust impact since most of the construction sites are adjacent to villages. The Contractor should fully implement the construction dust mitigation measures as appropriately.


ES.10.   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.11.   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.12.   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.
