2.1.1
Tolo Highway and Fanling Highway are expressways
in the North East New Territories connecting Sha Tin,
Tai Po and Fanling. These highways form a vital part of the
strategic Route 1, which links Hong Kong Island to Shenzhen. At present, this section of Route 1 is a
dual 3-lane carriageway. However,
at several major interchanges along this section of Route 1, the highway is
only dual-2 lane. Severe congestion
is a frequent occurrence during peak periods, particularly in the Kowloon bound
direction.
2.1.2
The
objective of the Widening of Tolo Highway / Fanling Highway between Island House Interchange and Fanling is to widen Tolo Highway
and Fanling Highway to dual 4-lane carriageway in
order to alleviate the current traffic congestion problems and to cope with the
increasing transport demands to and from the urban areas and also cross
boundary traffic.
2.1.3
The
construction works for the Widening of Tolo Highway /
Fanling Highway between Island House Interchange and Fanling are to be delivered in 2 stages:
Stage 1 ¡V Construction works between Island House Interchange and Tai Hang; and
Stage 2 ¡V Construction works between Tai Hang and Wo Hop Shek Interchange.
2.1.4
The
construction works of Stage 1 under the EP commenced in November 2009 and was planned
to be completed in December 2013 tentatively. The works of Stage 2 was planned to
commence in November 2013 and complete by end of 2016. Hyder-Arup-Black
and Veatch Joint Venture (HABVJV) was appointed by the Highways Department (HyD) as the consultants for the design and construction
assignment for the Project. Mott
MacDonald Hong Kong Ltd is the Independent Environmental Checker (IEC) of both
Stage 1 and Stage 2 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
4.1Table 4.1.

4.2.2
The
HVS and its accessories were maintained in good working condition, such as
replacing motor brushes routinely and checking electrical wiring to ensure a
continuous power supply.
4.2.3
Calibration
of the HVS (five point calibration) using Calibration Kit was carried out every
two months. The HVS calibration
orifice will be calibrated annually.
Calibration certificate of the TE-5025A Calibration Kit and the HVS are
provided in Appendix C.
4.3.1
Air
quality monitoring was conducted at the location specified in the Updated
EM&A Manual. Table

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
is provided in Appendix E.
4.7.1
The
monitoring results for 1-hr and 24-hr TSP are summarised in Table

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
¡V 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.

6.6.1 The parameters of in-situ measurements included water depth, dissolved oxygen (DO), dissolved oxygen saturation (DOS), turbidity level, pH value and water temperature.
6.6.2 Since water depths for all monitoring stations were less than 1m throughout the whole baseline measurement period, only mid-depth level was monitored.
6.6.3
At each monitoring station, at
least duplicate readings of dissolved oxygen content and turbidity were taken. The
probes were retrieved out of the water after the first measurement and then
re-deployed for the second measurement.
6.6.4 Water samples were collected by the water sampler and filled into polyethylene bottles for laboratory determination of suspended solids. Sampling bottles were pre-rinsed with the same water samples, and filled up to the rim, capped tightly and labeled immediately. The sample bottles were then packed into a cool-box kept at 4¢XC, and delivered to a HOKLAS accredited laboratory, Enviro Labs Ltd. (HOKLAS no.: 128) for analysis. The results for laboratory analysis of suspended solids are presented in Appendix I.
