Monitoring Equipment and Methodology Air Quality

24-Hr TSP

4.10 The 24-Hr TSP monitoring was undertaken in accordance with the Code of Federal Regulations Chapter 1 (Part 50) Appendix B. For all monitoring events, 24-Hr TSP was determined by drawing air through a pre-conditioned, pre-weighed glass fiber filter inside a high volume air sampler (HVAS) at a controlled flow rate for 24 hours ± 5 minutes.

4.11 The HVAS was calibrated once every six months in accordance with the manufacturers instruction using the NIST-certified standard calibrator (Graseby G-2535 Calibration Kit).

4.12 The 24-Hr TSP monitoring was carried out at six stations AM2, AM4, AM5, AM7, AM8 and AM9.

1-Hr TSP

4.13 1-Hr TSP levels were determined by using the 1-Hr TSP portable meter (TSI DustTrak Laser Dust Monitor), which is capable of measuring and recording 1-Hr weighted average dust concentration between 0.01 and 100 µg/m3. This portable dust meter was calibrated by the manufacturer before the instrument was shipped to the site. The zero response of the instrument was checked before and after each monitoring event.

4.14 All relevant meteorological data including temperature, rainfall, relatively humidity, wind speed, identification and weight of the filter paper, and on-site/off-site potential dust sources were recorded in details.

4.15 The calibration certificates of the 1-Hr TSP and 24-Hr TSP of air monitoring equipment were available for inspection upon request.

Noise

Noise Level: Leq (30 min.) by 6 consecutive Leq (5 min.) for Regular Noise Monitoring and Ad-Hoc Noise Monitoring Leq (15 min.) by 3 consecutive Leq (5 min.) for Restricted Hour Noise Monitoring

4.16 All noise monitoring works were undertaken using a Rion NL–31 IEC Type I sound level meter

and associated acoustic calibrator.

4.17 The sound level meter was mounted on a tripod at a height of 1.2 m and placed at the assessment point. The meter was oriented such that the microphone was pointing to the site with the microphone facing perpendicular to the line of sight. A windshield was fitted throughout all measurements.

4.18 All noise measurements were made with the meter set to FAST response and on the A-weighted scale. Consecutive six measurements of 5-minute equivalent continuous sound pressure level (LAeq5) readings were recorded over the monitoring period of 30 minutes at each station between 0700-1900 at normal weekdays. For other time period, consecutive three measurements of 5-minute equivalent continuous sound pressure level (LAeq5) readings were recorded, only when construction works of this project is carried out. In addition, L10 and L90 readings were also recorded.


12

4.19 The sound level meter was calibrated using an acoustic calibrator, prior to and after each set of measurements, measurements may be accepted as valid only if the calibration level from before and after the noise measurement agree to within 0.1 dB(A).

4.20 The calibration certificate of the sound level meter used for the noise monitoring works was available for inspection upon request.

Laboratory Analysis

4.21 All laboratory analyses in relation to the air quality monitoring were undertaken by a local HOKLAS-accredited laboratory.

QA/QC Procedures

4.22 AUES has implemented in house QA/QC procedures for all monitoring practices to ensure the validity of monitoring data. Blank filters samples were collected and delivered to the HOKLAS-accredited laboratory for QA/QC check.
