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 21st Monthly EM&A Report for the Contract which summaries findings of the EM&A programme during the reporting period from 1 December 2022 to 31 December 2022. 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.    Two exceedances in Action Level were recorded for the ecological monitoring of birds on 14 and 15 December 2022. These include significant declines in point count method result for species diversity of species with conservation importance; and transect walk method result for species diversity of all avifauna species in the community. However, the exceedances were not project-related.

vii.     No corrective actions were required according to the Event and Action Plans for the Monitoring Parameters.

Land Contamination

 

viii.    Regular site inspection was carried out to ensure the recommended mitigation measures are properly implemented. The signed final Contamination Assessment Report (CAR) for “Main Storeroom & Workshops”, “Mechanical Workshop”, “Waste Storage Area” and “SAS Thickener House-1” were submitted to EPD respectively on 1st November 2021, 23rd November 2021, 29th April 2022 and 6th July 2022. No contaminated soil and ground water was found within the Main Storeroom & Workshop, Mechanical Workshop, Waste Storage Area and SAS Thickener House-1, and no remedial action is required for both locations.

Complaint Log

ix.    No complaints were received in the reporting period.

Notifications of Summons and Successful Prosecutions

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

Reporting Change

 

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

Future Key Issues

 

xii.    The main works will be anticipated in the next three months are as follow:
