The proposed
widening of Tolo Highway and Fanling Highway between Island House Interchange
and Fanling (the Project) is a Designated Project under the Environmental
Impact Assessment Ordinance (Cap. 499) (EIAO). An Environmental Impact
Assessment (EIA) Report (the approved EIA Report) together with an
Environmental Monitoring and Audit (EM&A) Manual (the approved EM&A
Manual) were completed and approved under the EIAO on 14 July 2000 (Register
Number: EIA-043/2000).
The objective of the Project
¡°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.
The Project is a
designated project and governed by an Environmental Permit (EP-324/2008) issued
by the EPD on 23 December 2008.
Subsequently, the EPD issued Variation of Environmental Permits of EP-324/2008/A,
EP-324/2008/B, EP-324/2008/C
and EP-324/2008/D on 31 January 2012, 17 March 2014, 27
March 2015 and 27 August 2015 respectively. The
current valid VEP was applied on 29 December 2016 and the VEP (EP-324/2008/E)
was subsequently granted on 26 January 2017.
The
construction works for this Project are delivered in 2 stages i.e. Stage 1
(between Island House Interchange and Tai Hang) and Stage 2 (between Tai Hang
and Wo Hop Shek Interchange). Stage
2 would be implemented under three works contracts. Contract No. HY/2012/06 ¡°Widening of
Fanling Highway ¨C Tai Hang to Wo Hop Shek Interchange¡± and the entrusted
portion to CEDD under Contract No. CV/2012/09 ¡°Liantang/Heung Yuen Wai Boundary
Control Point Site Formation and Infrastructure Works ¨C Contract 3¡±. In addition, Contract No. ¡°Provision of
Bus-Bus Interchange on Fanling Highway Kowloon Bound¡± was carried out within
the site boundary of Contract No. 02/HY/2015. This report focuses on Contract No. HY/2012/06 ¡°Widening of Fanling Highway ¨C Tai Hang to
Wo Hop Shek Interchange¡± in Stage

areas are shown in Figure 1.1 and Figure 1.2 respectively.
1.3.3
The environmental mitigation measures implementation schedule are
presented in Appendix C.
2.1.1
The updated EM&A Manual has designated 1 air quality
monitoring station and 2 noise monitoring stations to monitor environmental
impacts on air quality and noise due to Stage 2 of the Project.
2.1.2
The updated EM&A Manual also requires environmental
site inspections for air quality, noise, water quality, chemical, waste
management, ecology and landscape and visual impacts.
2.2.1
For air quality monitoring, the monitoring station was set
up at Fanling Government Secondary School, in accordance with updated EM&A
Manual. The location is shown in Figure 1.3a.
2.2.2
For noise monitoring, the monitoring stations
M2 and M3 were set up at West Tai Wo and Fanling Government Secondary School
respectively in accordance with updated EM&A Manual. Figure 1.3a-b shows
the locations of the monitoring stations.
2.3.1
The environmental quality performance limits (i.e.
Action/Limit Levels) of air quality monitoring were derived from the baseline
air quality monitoring results at the monitoring station (AM2); while the
environmental quality performance limits of noise monitoring were defined in
the EM&A Manual.
2.3.2
The environmental quality performance limits are given in
Appendix D.
2.4.1
Relevant environmental mitigation measures were stipulated
in the Particular Specification and EP for the Contractor to adopt. A list of
environmental mitigation measures and their implementation statuses are given
in Appendix C.
2.5
Environmental
Impact Hypotheses Tested
2.5.1
The EIA Report concluded that with proper mitigation
measures implemented, fugitive dust emission during the construction phase
would be controlled and will not exceed the acceptable criteria.
2.5.2
For construction noise, exceedances were
predicted only at 2 schools (SR41 Wong Shiu Chi Middle School and
SR45 HK Teacher¡¯s Association Secondary School) but they are out of
the scope of this EM&A Programme. Hence, the EIA did not
anticipate any noise exceedances during the construction phase within
the scope of this EM&A Programme.
2.5.3
The above criteria have been tested under this EM&A
Programme during the reporting period.
3.1.1
In accordance with the updated EM&A Manual, baseline
1-hour and 24-hour TSP levels at one air quality
monitoring station was established. Impact
1-hour TSP monitoring was conducted for at least three times every 6 days, while
impact 24-hour TSP monitoring was carried out for at least once every 6 days.
3.1.2
The weather was mostly sunny, occasionally fine, cloudy and
rainy days in the reporting period. Weather information including the wind
speed and wind direction is annexed in Appendix F. The information was obtained
from the Hong Kong Observatory.
3.1.3
The monitoring results for 1-hour TSP and 24-hour TSP
monitoring are summarized in Tables 3.1 and 3.2 respectively. Detailed impact
