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

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.

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.

complaint was received in the reporting month.
Major construction site activities for the coming month are listed as below:-
· Construction of footpath and railing;
· Installation of plumbing & irrigation points;

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