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 20th Monthly
EM&A Report for the Contract which summaries findings of the EM&A
programme during the reporting period from 1 November 2022 to 30 November 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 10 November 2022. These include significant declines in
point count method results for the species diversity of all avifauna species in
the community; and species diversity of species of conservation importance only.
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:
9. NON-COMPLIANCE,
COMPLAINTS, NOTIFICATIONS OF SUMMONS AND SUCCESSFUL PROSECUTIONS
10. IMPLEMENTATION
STATUS OF ENVIRONMENTAL MITIGATION MEASURE
