EXECUTIVE SUMMARY

This report documents the findings of EM&A works conducted during the period between November 20156 and October 20167.

The impact stage EM&A programme for the Project includes air quality, noise and water 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, 75 exceedance events were recorded and the exceedances were concluded not related to the Project. No necessary remedial actions have been taken.

No environmental non-compliance was noted. No environmental complaint was received. No environmental related prosecution or notification of summons was received in the reporting period.

The box culvert works have been partially completed by the end of March 2014 except the last construction activity, i.e. installation of a base slab at Box Culvert ID4. The box culvert works had been completed in March 2017. The 4-week post-construction water quality monitoring at I5 was completed in 28 April 2017The box culvert works have been partially completed by the end of March 2014 except the last construction activity, i.e. installation of a base slab at Box Culvert ID4. Due to the loading requirement of a fresh water main under the box culvert, installation of the base slab at Box Culvert ID4 has been scheduled to be commenced in December 2016. The 4-week post construction water quality monitoring will be conducted after the installation of the base slab finishes, hence the completion of the box culvert works. As such, impact monitoring for water quality is anticipated to be resumed in December 2016 during the course of remaining box culvert works.

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 20165 and October 20167.

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 For water quality, it is also anticipated that with proper protection measures being implemented, the water quality during construction phase would be locally confined and controllable.

2.1.4 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 and water quality have been monitored. The specific parameters, monitoring frequency and the respective Action and Limit Levels are given in Table 2.1Table 2.1 and the location of the monitoring station is shown in the Figure 2.

2.2.2 The Event and Action Plan for the occurrence of non-compliance of the criteria of the monitoring parameters is annexed in Appendix C.

Temporary Suspension of Box Culvert Works and Water Quality Monitoring

1.1.1 The box culvert works have been partially completed by the end of March 2014 except the last construction activity, i.e. installation of a base slab at Box Culvert ID4. Due to the loading requirement of a fresh water main under the box culvert, installation of the base slab at Box Culvert ID4 has been scheduled to be commenced in December 2016. The 4-week post construction water quality monitoring will be conducted after the installation of the base slab finishes, hence the completion of the box culvert works. As such, impact monitoring for water quality is anticipated to be resumed in December 2016 during the course of remaining box culvert works.

3.2.3 The Contractor has been reminded to strengthen the mitigation measures including:

Air Quality

· All vehicles should be washed to remove any dusty materials before leaving the construction site.

· Ensure all vehicles are properly washed to remove mud and debris before leaving the site.

· Stockpiling shall be covered to avoid dust generation

Chemical and Waste Management

· Good housekeeping should be maintained and stagnant water should be removed from secondary containment regularly.

· Provide proper chemical and chemical waste management.

· A spill response procedure shall be in place and absorption material available for minor spillages.

· Ensure all chemical drums on site to be placed on drip tray

· Refuse shall be cleared frequently to provide sufficient waste skip for workers and keep site work area clean

· Housekeeping shall be enhanced and refuse shall be collected regularly

Water Quality

· Surface run-off, rainwater and waste water from construction site discharged into appropriate drains via adequately designed sand/ silk removal facilities (e.g. sand traps, sile traps and sedimentation basins) and pH adjusted before discharge.

· Ensure the de-silting facilities are cleared frequently to prevent direct discharge of construction site runoff

· Implement sufficient mitigation measures to avoid runoff leakage from road works areas and divert site effluent to wastewater treatment facilities

· Silt removal facilities, channels and manholes should be well inspected and maintained regularly;

· All plant and equipment should be well maintained and in good operating condition to avoid black smoke emission;

· Water treatment facilities should be properly maintained and avoid untreated water entering storm drain;

· Proper drainage channels/bunds should be provided at the site boundaries to collect/intercept the surface run-off from works areas;

· Water spraying or covering of tarpaulin should be properly implemented whenever necessary for the unpaved roads, access roads and construction areas;

· All vehicles should be washed to remove any dusty materials before leaving the construction site;

· Vessels and equipment operating should be checked regularly and properly maintained;

· Secondary containment, like drip trays and/or bundings, should be provided for all chemical containers to retain any oil/chemical waste leakage within the construction site;

· Chemical waste should be stored, handled and disposed of properly; and

· On site segregation should be implemented as far as practicable for reuse and recycle.

5 REVIEW OF THE VALIDITY OF EIA PREDICTIONS

5.1.1 The EIA report predicted that with proper implementation of the mitigation measures for air, noise and water quality, environmental impact would be locally confined and controllable. During the reporting period, 75 exceedances were recorded and the exceedances were concluded not related to the Project. Hence, it is considered that the EIA predictions is valid for the reporting period.

6.1.2 The box culvert works have been partially completed by the end of March 2014 except the last construction activity, i.e. installation of a base slab at Box Culvert ID4. The box culvert works had been completed in March 2017. The 4-week post-construction water quality monitoring at I5 was completed in 28 April 2017.Due to the loading requirement of a fresh water main under the box culvert, installation of the base slab at Box Culvert ID4 has been scheduled to be commenced in December 2016. The 4-week post construction water quality monitoring will be conducted after the installation of the base slab finishes, hence the completion of the box culvert works. As such, impact monitoring for water quality is anticipated to be resumed in December 2016 during the course of remaining box culvert works.
