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 7th Quarterly EM&A Summary
Report for the Contract which summaries findings of the EM&A programme
during the reporting period from 1 October 2022 to 31 December 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 four (4)
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”, “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
