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

areas are shown in Figure 1.1 and Figure 1.2 respectively.
1.3.4
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
