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 1st Monthly EM&A Report for the Contract
which summaries findings of the EM&A programme during the reporting period
from 8 April 2021 to 30 April 2021. As informed by the Contractor, major
activities in the reporting month were:
¡P
Overhaul
of Detritor;
¡P
Overhaul
of Primary Sedimentation Tank and Final Sedimentation Tank;
¡P
Overhaul
of Sludge Holding Tank and Sludge Digestion Tank;
¡P
Pre-drill
work by 4 drill rig;
¡P
Installation
of instrumentation;
¡P
Site
formation work at IW within piling area;
¡P
Site
formation works at temporary storage area, admin. Building & work shop;
¡P
Erection
of noise barrier;
¡P
Erection
of bird curtain; and
¡P

pit for zone 1 diversion work & pre-drill work.
Breaches of Action and Limit Levels
iii. No Action and Limit Level exceedance was recorded for air
quality monitoring and construction noise monitoring in the reporting month.
iv. An Action Level exceedance was recorded for water quality in
the reporting month. The exceedance was recorded at M3 on 13 April 2021. It was
found that this exceedance is not project related.
v. No Action / Limit exceedance was recorded for noise levels at
stations (NMS1 and NMS2) in close proximity to the active ardeid night roosts.
vi. Action and Limit levels for the ecological bird monitoring
were not computed due to insufficient data for comparison. Due to the safety
concern encountered during the night-time survey, the monitoring activity was
stopped because of the potential attacks by the village dogs. Night-time survey
activity was suspended to avoid further safety incident. Safety issues shall be
addressed, specifically coordinating with and requesting the dog owners to keep
their dogs within their premises during the duration of the night-time survey.
In connection to this, continued coordination with the dog owners and/or
village representative is currently being undertaken to ensure that the dogs be
kept within their owners¡¦ premises during the monthly ecological survey period;
and/or engage dog owners or local villagers (each from Fung Lok Wai and Nam
Sang Wai) to accompany the team during the monitoring activities.
Complaint Log
vii. No complaints were received in the reporting period.
Notifications of any Summons and
Successful Prosecutions
viii. No notifications of summons and prosecutions were received in
the reporting period.
Reporting Change
ix. There were no reporting changes during the reporting month.
