This report documents the findings of EM&A works conducted during
the period between November 2018 and October 2019.
The impact stage EM&A programme for the Project includes air quality
and, noise quality monitoring.
The EM&A programme was carried out by the
ET in accordance with the EM&A Manual requirements. It is concluded from the environmental monitoring
and audit works that adequate environmental mitigation measures have been
implemented by the civil works contractors where appropriate in the reporting period.
In the reporting period, no exceedance event was
recorded. No necessary remedial actions
have been taken.
No environmental non-compliance was noted. One environmental complaint was
received,.
which was
concluded that it was
unlikely due to the construction works of this Project after
investigations, was received. No environmental related prosecution or
notification of summons was received in the reporting period.
1.1.1
The
Project is a Designated Project under the Environmental Impact Assessment
Ordinance (EIAO) (Cap. 499). An
Environmental Impact Assessment (EIA) Report together with an Environmental
Monitoring and Audit (EM&A) Manual were approved on 14 July 2000 (Register
Number: EIA-043/2000). The Project
is governed by an Environmental Permit (EP) (EP-324/2008) which was granted on
23 December 2008. A variation of EP
(VEP) was applied and the VEP (EP-324/2008/A) was subsequently granted on 31
January 2012. An additional VEP has
been applied on 24 February 2014 and the VEP (EP-324/2008/B) was subsequently
granted on 17 March 2014. Furthermore, an additional VEP has been applied on 9 March 2015 and the VEP
(EP-324/2008/C) was subsequently granted on 27 March 2015. The previous VEP
(EP-324/2008/D) was granted on 27 August 2015. The current VEP (EP-324/2008/E)
was granted on 26 January 2017.

This
is the Annual EM&A Review Report which summaries
the impact monitoring results and audit findings for the Project during the
reporting period between November 2018 and October 2019.
2.1.1
The
EIA Report concluded that with proper mitigation measures implemented, fugitive
dust emission during construction phase would be controlled and will not exceed
the acceptable criteria.
2.1.2
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 construction phase within the scope of this EM&A Programme.
2.1.3
The
above criteria have been tested under this EM&A Programme during the
reporting period.
2.2.1
In
accordance with the Updated EM&A Manual, environmental parameters including
air quality, noise have been monitored.
The specific parameters, monitoring frequency and the respective Action
and Limit Levels are given in Table 2.1 and the location of the monitoring
station is shown in the Figure 2.

of dusty material shall be covered by impervious sheeting entirely.
·
Vehicle
washing facility shall be provided at all site exits to wash away any dusty
materials from vehicle before they leave the site.
·
Mud
and debris shall be removed to prevent potential muddy water flow to public
road.
·
Secondary
containment shall be provided for chemical to prevent potential leakage.
