i. This Quarterly
Environmental Monitoring and Audit (EM&A) Summary 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 5th Quarterly EM&A Summary
Report for the Contract which summaries findings of the EM&A programme
during the reporting period from 1 April 2022 to 30 June 2022. As informed by
the Contractor, major activities in the reporting period were shown in
section 1.4.1.
iii. The EM&A
methodology has been effective in monitoring the environmental impacts of the
Project and the effectiveness of the mitigation measures. The data collected
were useful in determining whether the Project had caused unacceptable impacts
on the sensitive receivers. Analysis of all EM&A data collected throughout
the baseline and the impact periods demonstrated the environmental
acceptability of the Project.
Breaches of Environmental Quality Performance Limits (AL levels)
iv. No Action and
Limit Level exceedance was recorded for air quality monitoring and construction
noise monitoring in the reporting period.
v. No Action and
Limit Level exceedance was recorded for water quality in the reporting period.
vi. No Action / Limit
Level exceedance was recorded for noise levels at stations (NMS1 and NMS2) in close proximity to the active ardeid night roosts during the reporting period.
vii. A total of two (2)
Action Level exceedances were recorded for the ecological monitoring of birds
during the reporting period. However, these exceedances were not project-related.
viii. No corrective
actions were required according to the Event and Action Plans for the
Monitoring Parameters.
Land Contamination
ix. 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” and “Waste Storage
Area” were submitted to EPD respectively on 1st November 2021, 23rd
November 2021 and 29th April 2022. No contaminated soil and ground water was
found within the Main Storeroom & Workshop, Mechanical Workshop and the
Waste Storage Area, and no remedial action is required for both locations. Part
of the Site investigation (SI) work within the SAS Thickener House-1 (i.e.
ENV-BH16, ENV-BH17, ENV-BH22 and ENV-BH23) was completed by 16th May
2022. While the laboratory results of sampling works show that there is no contaminated soil or groundwater within
the SAS Thickener House-1, the findings are summarized in the draft CAR for the
area which is under review and will be submitted to EPD.
Complaint Log
x. No complaints were
received in the reporting period.
Notifications of Summons and Successful
Prosecutions
xi. No notifications
of summons and successful prosecutions were received in the reporting period.
Reporting Change
xii. There were no
reporting changes during the reporting period.
