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 November 2008, during the normal working are summarised in Table 3.1.

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 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
4^th November 2008	65	73	56
24^th November 2008	65	73	54

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 4^th, 12^th, 18^th and 24^th

· Rubbish was accumulated on the slope and in the U-channel near San Tin Tsuen Road works area. The contractor was reminded to collect and dispose of the rubbish properly and regularly.
