EXECUTIVE SUMMARY

A) Introduction

 

This is the monthly Environmental Monitoring and Audit (EM&A) Report prepared by Cinotech Consultants Limited for the project “Construction of Yuen Long Bypass Floodway” (the Project).  This report documents the findings of EM&A Works conducted in April 2006 (26th of each month as the cut-off day, i.e. 26th July 2006 to 25th August 2006).

 

The construction activities undertaken in the reporting month were:

 

·          Construction of footpath and railing;

·          Installation of plumbing & irrigation points;

·          Paving and road works; and

·          Landscape works

B) Environmental Monitoring Works

 

Environmental monitoring for the Project was performed regularly as stipulated in the Updated EM&A Manual and the results were checked and reviewed. Site audits were conducted once per week. Implementation of the environmental mitigation measures, Event Action Plans and environmental complaint handling procedures were also checked.

 

B1 Air Quality

 

1-hour TSP Monitoring

 

The 1-hour TSP monitoring was conducted as scheduled except the monitoring at Station B on 1, 4, 7, 9, 14, 15 and 17 August 2006. The Station B was not accessible to the monitoring team during the summer holiday of the school which was closed in these days. No Action/Limit Level exceedance was recorded in the reporting month.

 

24-hour TSP Monitoring

 

The 24-hour TSP monitoring was conducted as scheduled except the monitoring at Station B on 2 and 8 August 06. The Station B was not accessible to the monitoring team during the summer holiday of the school which was closed in these days. No Action/Limit Level exceedance was recorded in the reporting month.

 

B2 Construction Noise

 

Construction noise monitoring was conducted as scheduled except the monitoring at all Stations on 3 August 06 due to hosting of Typhoon Signal No. 3 as well as at Station B on 9 and 17 August 06 when the school was closed for summer holiday. No Action/Limit Level exceedance was recorded in the reporting month.

 

B3 Water Quality

 

Water quality monitoring was conducted as scheduled. The DO concentration (3.8 mg/L) at W1 measured on 15 August 06 did not comply with the Compliance Level but within the baseline level (2.2-9.4mg/L). In addition, no construction activity was undertaken adjacent to the monitoring location. The non-compliance of DO level is therefore considered not due to the project activity. No further action was required.

C) Environmental Licensing and Permitting

 

License/Permits granted to the Project include the Further Environmental Permit (FEP), Variation of Environmental Permit (VEP), Wastewater Discharge License, Chemical Waste Producer Registration and Construction Noise Permit (CNP). The FEP for the Project was attached in the monthly EM&A report for March 2003. The VEP were attached in the monthly EM&A report for May 2003. The Chemical Waste Producer Registration was attached in the monthly EM&A report for January 2004. The Wastewater Discharge License was attached in the monthly EM&A report for June 2004.

D) Complaints and Prosecutions

 

No environmental prosecution and complaint was received in the reporting month.

E) Future Key Issues

 

Major construction site activities for the coming month are listed as below:-

 

·          Construction of footpath and railing;

·          Installation of plumbing & irrigation points;

·          Paving and road works; and

·          Landscape works

 

Construction dust and wastewater discharge during construction work is anticipated to be the future key issue.
