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 July 2008, during the normal working hours and night-time restricted hours (2300 to 0700 hours of next day) are summarised in Table 3.1 and Table 3.2, respectively. 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
2^nd July 2008	65	72	56
15^th July 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.

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.

(2) * Noise measurement at CM1and CM2 was cancelled due to sudden rainstorm.

3.2 Water Quality Monitoring

Visual site surveillances for water quality were undertaken on 2^nd, 9^th, 15^th and 23^rd July 2008. The key observations from the visual inspection include:

· Deposited sands and silts were accumulated in the sand trap and U-channels near San Tin Highway Works Area due to the recent rainstorm. The Contractor was reminded to remove the deposited sand and silts from the drainage system regularly.

· Stagnant water pool was seen in the works area near Castle Peak Road and in broken water-filled barrier near the San Tin Interchange. The Contractor was reminded to backfill the works area and to replace the broken water-filled barrier as soon as possible to avoid the stagnant water from accumulating.

· Uncontrolled site runoff was observed near site office in West Abutment works area. The Contractor was reminded to properly divert the site runoff to sedimentation facility before discharge to the public drains.

· Rubbish and leaves were accumulated in the V-channel in South Abutment Works Area. The Contractor was reminded to collect and dispose of the rubbish and leaves properly to maintain free water free flow.

· Brownish water was seen in the U-channel near the site office. The Contractor was reminded to pump out the brownish water.

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 in July 2008.

During the inspection, two transplanted trees at N1 Division near the site office appeared to be dead. Compensatory planting should be providing. Overgrown weeds were seen inside the planting area behind the site office in N1 Division and N2 Division. The Contractor was reminded to remove the weeds regularly as proper maintenance.

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

3.4 Ad-hoc Air Quality Monitoring
