EXECUTIVE SUMMARY

 i.    This Monthly Environmental Monitoring and Audit (EM&A) Report is prepared for Contract No. SPW 07/2020 “Environmental Team for Construction of Yuen Long Effluent Polishing Plant Stage 1”. Drainage Services Department (DSD) has appointed Fugro Technical Services Limited (FTS) to undertake the Environmental Team services for the project and implement the EM&A works.

ii.    This is the 9th Monthly EM&A Report for the Contract which summaries findings of the EM&A programme during the reporting period from 1 December 2021 to 31 December 2021. As informed by the Contractor, major activities in the reporting month were:

 

Breaches of Environmental Quality Performance Limits (AL levels)

 

iii.     No Action and Limit Level exceedance was recorded for air quality monitoring and construction noise monitoring in the reporting month.

iv.    No Action and Limit Level exceedance was recorded for water quality monitoring in the reporting month.  

v.    No Action / Limit exceedance was recorded for noise levels at stations (NMS1 and NMS2) in close proximity to the two active ardeid night roosts (ANR1 and ANR2) observed within the Survey Area during the reporting month.

vi.    No Action / Limit exceedance for the ecological monitoring of birds in the reporting month.

vii.     No corrective actions were required according to the Event-Action Plans.


 

Land Contamination

 

viii.    Regular site inspection was carried out to ensure the recommended mitigation measures are properly implemented. Site investigation (SI) work was completed by 4th August 2021 and the signed final Contamination Assessment Report (CAR) for Main Storeroom & Workshops was submitted to EPD on 1 November 2021. The signed final Contamination Assessment Report (CAR) for Mechanical Workshop was submitted to EPD on 23rd November 2021. No contaminated soil and ground water was found within the Main Storeroom & Workshop and the Mechanical Workshop, hence no remedial action is required.

Complaint Log

ix.    No complaints were received in the reporting period.

Notifications of any Summons and Successful Prosecutions

x.    No notifications of summons and prosecutions were received in the reporting period.

Reporting Change

xi.    There were no reporting changes during the reporting month.
