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 2 of the Project and ¡°Provision of Bus-Bus Interchange on Fanling Highway Kowloon Bound¡± under Works Order Nos.
CB128520-5 and CB128519-0 in Contract No. 02/HY/2015 ¡°Highway Department Term
Contract (Management and Maintenance of Roads in Tai Po and North District
excluding High Speed Roads 2016-2022)¡±. The construction works of Works Order Nos. CB128520-5 and CB128519-0
under Contract No. 02/HY/2015 have been completed on 23 May 2018.
Pursuant to
the EP (EP-324/2008/E) Condition 2.7, the Capture Survey Trip Report
for Ma Wat River Northern Meander (Version 2) for the Project was submitted on
24 December 2013 by the Environmental Team (ET) and verified by the Independent
Environmental Checker (IEC) on 6 January 2014.

Breaches of Action
and Limit Levels for Air Quality
No
exceedance of Action and Limit Level was recorded for 1-hour and 24-hour TSP
monitoring in the reporting period.
Breaches of Action
and Limit Levels for Noise
No Action Level exceedance of construction noise
was recorded in the reporting period. No noise complaints related to 0700 ¨C

exceedance at M3 is considered to be contributed from
background noise, possibly traffic noise from Pak Wo Road and Fanling Highway. The exceedance was considered
non-project-related.
One (1) Limit Level exceedance was recorded on 20
June 2019 for noise monitoring at M3 in the previous reporting month. The
exceedance at M3 is considered to be contributed from
background noise, possibly traffic noise from Pak Wo Road and Fanling Highway. The exceedance was considered
non-project-related.
Complaint,
Notification of Summons and Successful Prosecution
No notification of summons and successful
prosecution was received in the reporting period.
One (1) noise-related complaint was
received on 28 October 2019. The complainant was regarded to the use of powered mechanical equipment
not in accordance with the conditions stipulated in the Construction Noise
Permit (CNP) - GW-RN0602-19 in Pak Wo Road near Fanling
Highway on 24 September 2019. The complaint was

The general layout plan of the
Project site of Contract No. HY/2012/06 and Works Order Nos. CB128520-5 and
CB128519-0 under 02/HY/2015 showing the contract
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.
2.5.1
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 and cloudy, occasionally fine
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
air quality monitoring results are presented in Appendix E.

1.
9.1.1
The impact air quality and noise monitoring programme ensured that any environmental impacts to the
receivers would be readily detected and timely actions could be taken to
rectify any non-compliance. The
environmental monitoring results indicated that the construction activities in
general were in compliance with the relevant
environmental requirements and were environmentally acceptable. The weekly site inspections ensured that
all the environmental mitigation measures recommended in the EIA/ERR were
effectively implemented. Despite the minor deficiencies found during site
audits, the Contractor has taken appropriate actions to rectify deficiencies
within a reasonable timeframe. Therefore, the effectiveness and efficiency of
the mitigation measures were considered high in most of the time.
9.1.2
For all the parameters under monitoring as mentioned in
Section 8, the measured levels were in line with the EIA and ERR predictions
generally. This indicates that the mitigation measures were effectively and
efficiently implemented.
2.
10.1.1
The environmental monitoring methodology was considered
well established as the monitoring results were found in line with the EIA
predictions.
10.1.2
As effective follow-up actions were promptly taken once
exceedances were recorded, no further exceedance occurred. The EM&A programme was considered successfully and adequately
conducted during the course of the reporting period.
