3 Monitoring Results

3.1 Noise Monitoring

3.1.1 Noise Monitoring Equipment

Details of the noise monitoring equipment are listed below and the calibration certificates are presented in Annex C:

· Sound level meter ONO-SOKKI LA-5110

· Acoustical calibrator ONO-SOKKI SC-2110

· Hand-held anemometer

3.1.2 Noise Monitoring Methodology

The sound level meter was calibrated with an acoustical calibrator prior to each measurement. It was set on a tripod at 1.2 m above local ground level at the monitoring station. Measurement of the A-weighted L_{eq(30
minutes)} noise level for normal daytime hours was undertaken. Three consecutive A-weighted L_{eq(5
minutes)} noise levels were measured for restricted hours monitoring. Wind speed was checked during the monitoring period using the hand-held anemometer to ensure steady wind speed did not exceed 5 m/s, or gusts did not exceed 10 m/s. After the noise measurement the sound level meter was re-calibrated using the acoustical calibrator.

3.1.3 Noise Monitoring Results

Noise monitoring was undertaken on a biweekly basis when noise generating activities were underway. The noise monitoring results obtained in August 2008, during the normal working is summarised in Table 3.1. There were no construction activities during restricted hours from 1900 to 2300 hours on normal working days and all day on general holidays within this reporting period.

There were no environmental exceedances of the Action and Limit Levels for noise monitoring recorded during the normal daytime hours within the reporting period. Details of the monitoring time period and weather condition during the monitoring period and the graphical presentation of the noise monitoring results are provided in Annex D.

Table 3.1 Summary of Noise Monitoring Results during Normal Working Hours

Date of Monitoring	Measured Noise Level L_{eq(30 minutes)} dB(A)
Date of Monitoring	CM1	CM2	CM3
18^th August 2008	65	73	56
29^th August 2008	65	73	55

Remark:

(1) CM2 is a non-façade measurement location. A positive correction of 3 dB(A) has been applied to the measured noise level at CM2 according to EPD’s guideline.

3.2 Water Quality Monitoring

Visual site surveillances for water quality were undertaken on 8^th, 12^th, 18^th and 27^th August 2008. The key observations from the visual inspection include:

· Deposited sands and silts were accumulated in the sand trap and U-channels near site office due to the landscape work. The Contractor was reminded to ensure the drainage system is free of debris for water flow.

· Stagnant water pool was seen in the works area near Castle Peak Road and sand trap in works area near San Tin Highway. The Contractor was reminded to clear the stagnant water promptly.

· Landscape materials were scattered in the U-channel in the Road Island amongst Roads D200, D100 and G100. The Contractor was reminded to remove the landscape materials to maintain site tidiness.

The details of the water quality visual inspection reports are provided in Annex E.

3.3 Landscape and Visual Resources

One site inspection on the landscape and visual resources was undertaken on 26^th August 2008.

During the inspection, some transplanted trees at M2 in South Division were seen to be in very poor condition. The Contractor was reminded to closely monitor the transplanted tress and to ensure the trees proper growth.

The details of the landscape and visual resources inspection report are provided in Annex F.
