Breach of Action
and Limit Levels for Air Quality
One (1) Action Level exceedance of 24-hour TSP
monitoring was recorded at the monitoring location AM1(SR77)
on 17 October 2014 in the reporting month. Investigation for the exceedance
was conducted which concluded that the exceedance was
not related to the project works.
The investigation report for the incident is presented in Appendix M.
No exceedance of
Action and Limit Level was recorded for 1-hour TSP monitoring at the monitoring
location AM1(SR77) in the reporting month.
Breach of Action
and Limit Levels for Noise
No noise complaint was received
in the reporting month, so no Action Level exceedance
was recorded. Also, no Limit Level exceedance of noise monitoring was recorded in the
reporting month.
Breach of Action
and Limit Levels for Water Quality
The box culvert works have been partially
completed by the end of March 2014 except the last construction activity,
installation of a base slab at Box Culvert ID4. Due to the loading requirement of a
fresh water main under the box culvert, installation of the base slab at Box
Culvert ID4 has to be scheduled to be carried out in November 2015 after the
utilities diversions complete. The
construction works are temporarily suspended until the utilities diversion
works complete. The 4-week post
construction water quality monitoring will be commenced after the installation
of the base slab finishes, hence the completion of the box culvert works.
Impact monitoring for water quality was not
necessary in the reporting month due to temporary suspension of the construction
works and is anticipated to be resumed in November 2015 during the course of
remaining box culvert works.

4.1.1
In accordance with the Updated
EM&A Manual, 1-hr and 24-hr total suspended particulate (TSP) levels at the
designated air quality monitoring station are required. Impact 24-hour TSP monitoring should be
carried out for at least once every 6 days. For the 1-hr TSP impact monitoring, the
sampling frequency of at least three times in every 6 days should be undertaken
when the highest dust impact occurs.
4.2.1
The 1hr- TSP and 24-hr TSP air
quality monitoring were performed using a High Volume Sampler (HVS), of which
its location and operation satisfy, as far as practicable, all the requirements
as specified in the Updated EM&A Manual. The brand and model of the equipment are
given in Table 4.1.

4.5.1
With the consideration of
criteria stated in the Updated EM&A Manual, the HVS was installed in the
vicinity of the air sensitive receivers.
4.5.2
The relevant data including
temperature, pressure, weather conditions, elapsed-time meter reading for the
start and stop of the sampler, identification and weight of the filter paper,
and any special phenomena observed were recorded. The weather information was referenced
from Hong Kong Observatory (http://www.weather.gov.hk/wxinfo/pastwx/extractc.htm).
4.5.3
A HOKLAS accredited laboratory
with constant temperature and humidity control, and equipped with necessary
measuring and conditioning instruments, to handle the 24-hr TSP samples, was
employed for sample analysis.
4.5.4
Filter papers of size
8"x10" were labelled before sampling. They were inspected to be clean with no
pin holes and conditioned in a humidity controlled chamber for over 24-hr and
were pre-weighed before use for the sampling.
4.5.5
The 24-hr TSP levels were
measured by following the standard high volume sampling method for TSP as set
out in the Title 40 of the United States Code of Federal Regulations, Chapter 1
(Part 50), Appendix B. TSP was
sampled by drawing air through a conditioned, pre-weighted filter paper inside
the HVS at a controlled air flow rate.
After 24-hr sampling, the filter papers loaded with dust were kept in a
clean and tightly sealed plastic bag, and then returned to the laboratory for
reconditioning in the humidity controlled chamber followed by accurate weighing
by an electronic balance with a readout down to 0.1 mg.
4.5.6
All the collected samples were
kept in a good condition for 6 months before disposal.
4.5.7
For 1-hr TSP monitoring,
monitoring methodology is the same as 24-hr TSP monitoring which has been
presented in Section
4.5.1 to Section 4.5.6, but with
sampling period changed to 1 hour.
4.6.1
The schedule for environmental
monitoring for the reporting month is provided in Appendix D. Meteorological
data extracted from Hong Kong Observatory for the reporting month

5.5.1
The monitoring procedures are summarised as
follows:
·
The sound level meter was set on a tripod at a height of 1.2 m above the
ground for free-field measurements at monitoring station SR77;
·
The battery condition was checked to ensure good functioning of the
meter;
·
Parameters such as frequency weighting, the time weighting and the
measurement time were set as follows:
·
Frequency weighting: A
·
Time weighting: Fast
·
Parameters: Leq, L10 and L90
·
Time measurement: Leq(30-minutes) during
non-restricted hours i.e. 07:00 – 19:00 hrs on normal weekdays
·
Prior to and after each noise measurement, the meter was calibrated
using the acoustic calibrator for 94dB(A) at 1000 Hz. If the difference in the calibration
level before and after measurement was more than 1dB(A), the measurement would
be considered invalid and repeat of noise measurement would be required after
re-calibration or repair of the equipment.
·
At the end of the monitoring period, the Leq,
L10 and L90 were recorded. In
addition, site conditions and noise sources were recorded on a standard record
sheet.
·
A façade correction of +3dB (A) shall be made to the noise parameter
obtained by free field measurement.

The Event and Action Plan for the occurrence of non-compliance of the
noise criteria is annexed in Appendix G.
6.1.1
The box culvert works have been
partially completed by the end of March 2014 except the last construction
activity, installation of a base slab at Box Culvert ID4. Due to the loading requirement of a
fresh water main under the box culvert, installation of the base slab at Box
Culvert ID4 has to be scheduled to be carried out in November 2015 after the
utilities diversions complete. The construction
works are temporarily suspended until the utilities diversion works
complete. The 4-week post
construction water quality monitoring will be commenced after the installation
of the base slab finishes, hence the completion of the box culvert works.
6.1.2
Impact monitoring for water quality was not
necessary in the reporting month due to temporary suspension of the
construction works and is anticipated to be resumed in November 2015 during the course
of remaining box culvert works.
7.1.1

·
Water spraying or covering of tarpaulin should be properly implemented whenever necessary for the unpaved
roads, access roads and construction areas.
·
All vehicles should be washed
to remove any dusty materials before leaving the construction site.
·
Wheel washing facilities
should be properly maintained to ensure proper functioning.
