EXECUTIVE SUMMARY

This report documents the findings of EM&A works conducted during the period between November 2019 and October 2020.

 

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 requirement.  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                 INTRODUCTION AND PROJECT INFORMATION

1.1              Background

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.

1.1.2         Chun Wo Construction & Engineering Co Ltd (Chun Wo) was commissioned by the Civil Engineering and Development Department (CEDD) as the Civil Contractor for the Entrusted Portion of Widening of Tolo Highway/Fanling Highway between Island House Interchange and Fanling Stage 2.  Meinhardt Infrastructure & Environment Ltd (MIEL) has been appointed by Chun Wo as the Environmental Team (ET) to fulfill the corresponding EM&A requirements pursuant to Environmental Permit No. EP-324/2008/D in accordance with the Updated EM&A Manual (dated October 2013) for Widening of Tolo Highway/Fanling Highway between Island House Interchange and Fanling Stage 2.  The EM&A programme commenced in 5 November 2013.

1.4              Purpose of the Report

1.4.1         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 2019 and October 2020.

2                 SUMMARY OF EM&A REQUIREMENTS

2.1              Environmental Impact Hypothesis under Monitoring

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              Monitoring Requirements

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.
