This is the 101st monthly Environmental Monitoring and
Audit (EM&A) report for the Project “Construction of Lamma Power Station
Extension” prepared by the Environmental Team (ET). This report presents the results of impact
monitoring on air quality and noise for the said project in September 2018.
The reclamation and submarine
pipeline works were completed with the first gas-fired combined cycle unit
(viz. Unit L9) commissioned in October 2006, working currently on base load
operation. To cope with the scheduled
retirement of the existing units at Lamma Power Station, the second gas-fired
combined cycle unit (viz. Unit L10) is planned for commercial operation in
early 2020 and the associated construction work commenced in February 2016.
In September 2016, the
Government approved HK Electric to construct the third combined cycle gas-fired
generating unit (L11) to implement the 2020 Fuel Mix Target. L11 is planned for commercial operation in
2022 and the associated construction work commenced in November 2016.
Air and noise
monitoring were performed. The results were checked
against
the established Action/Limit (AL) levels. An on-site audit was conducted once per week.
The implementation status of the environmental
mitigation measures, Event/Action Plan and environmental
complaint handling procedures were also checked.

Monitoring Procedures and Calibration Details
MINIVOL (24- hour TSP Monitoring):
Preparation
of Filter Papers
·
Visual inspection
of filter papers was carried out to ensure that there were no pinholes, tears
and creases;
·
The filter papers
were then labeled before sampling.
·
The filter papers
were equilibrated at room temperature and relative humidity < 50% for at
least 24 hours before weighing.
Field Monitoring
·
During collection
of the sampled filter paper, the information on the elapse timer was
logged. Site observations around the
monitoring stations, which might have affected the monitoring results, were
also recorded. Major pollution sources,
if any, would be identified and reported.
·
The post-sampling
filter papers were removed carefully from the filter holder and folded to avoid
loss of fibres or dust particles from the filter papers;
·
The filter holder
and its surrounding were cleaned;
·
A pre-weighed
blank filter paper for the next sampling was put in place and aligned
carefully. The filter holder was then
tightened firmly to avoid leakage;
·
The programmable
timer was set for the next 24 hrs sampling period;
·
The post-sampling
filter papers were equilibrated at room temperature and relative humidity <
50% for at least 24 hours before weighing.
TEOM continuous
dust monitor (24- hour TSP and 1- hour TSP Monitoring):
·
The following
parameters of the TEOM model dust meters are regularly checked to ensure proper
functionality:
o
Operation Mode;
o
Frequency of the
tapered element;
o
Main flow;
o
Bypass flow.
Maintenance
& Calibration
·
The monitoring
equipment and their accessories are maintained in good working conditions.
·
Monitoring equipment
is calibrated at monthly intervals.
Calibration details are shown in Appendix F.
All dust monitoring works were conducted on schedule. All monitoring data and graphical
presentation of the monitoring results are provided in Appendix
D. Key findings and observations are
provided below:
1-hour

Continuous noise alarm
monitoring at Ash Lagoon/Ching Lam were carried out to calculate the noise contributed by the construction activities
at the two critical NSR’s, viz. Long Tsai Tsuen/Hung Shing Ye and the school
within the village of Tai Wan San Tsuen. The
impact monitoring data for construction noise were checked against the limit levels specified in the EM&A Manual. With the availability of the construction noise
permits, impact monitoring for the construction work during the restricted
hours was also carried out. Section 3
presents the details of the construction noise permits.
The impact noise monitoring data were checked against the limit levels specified in the EM&A Manual. Appendix B shows the established Action/Limit Levels for
noise.
In accordance with the
EM&A manual, the identified noise monitoring locations of Ash Lagoon and
Ching Lam are shown in Figure 3.1.
The sound level meters
used for noise monitoring complied with International Electrotechnical
Commission Publications 651:1979 (Type 1) and 804:1985 (Type 1). The noise monitoring equipment used is shown
in Table 3.1.

Procedures
Continuous Noise
Monitoring for Lamma Extension Construction
The measured noise levels (MNL's)
were collected at the
noise alarm monitoring stations at Ash Lagoon and Ching Lam. The notional
background noise levels (viz. baseline noise data at
Ash Lagoon and Ching Lam) were applied to correct the corresponding MNL's in 30-min/5-min LAeq.
A wind speed sensor was
installed at Station Building Rooftop.
The wind speed signal was used to determine whether the
data from Ash Lagoon and Ching Lam noise alarm monitoring stations were
affected. The instantaneous data was discarded in case the instantaneous wind speed exceeded 10 m/s. The 30-min/5-min LAeq
was considered valid only if the amount of valid data was equal to or above 70%.
Equipment
Calibration
The sound level meters and
calibrators were verified by the manufacturer or accredited laboratory. With the endorsement of the Independent
Environmental Checker, the enhancement of calibration of sound level meter at
the noise monitoring stations was implemented.
The monthly manual on-site calibration using sound level calibrator was
replaced by the daily auto charge injection calibration function of the sound
level meter. For additional quality
assurance, manual on-site calibration would still be conducted for the noise
monitoring stations once every 6 months.
Manual on-site calibration was carried out for Ching Lam noise
monitoring station in September 2018.
The next on-site calibrations for Ash Lagoon and Ching Lam noise
monitoring stations would be carried out in February and March 2019
respectively.
Continuous noise
monitoring was conducted at the two monitoring stations at Ash Lagoon and Ching
Lam.
All monitoring results
and their graphical presentations are provided in Appendix E. No
exceedance of noise Action/Limit Level was recorded in the month.
