3.1.5 Monitoring Procedures and Calibration Details i. Calibration Procedures - Calibration procedures of HVS are as follows (calibration certificates are presented in Appendix G3) : a. A certified orifice transfer standard with a calibration curve was used for the calibration. b. The transfer standard was connected to the inlet of the sampler. The orifice manometer was then connected to the orifice pressure port. The manometer’s connecting tubing was inspected to make sure that there are no leaks between the orifice unit and the sampler. c. The motor was then disconnected from the flow controller and plugged directly to an AC power source. d. A weather station has been setup at the Site Office to measure and record the ambient temperature, Ta (K) and the barometer pressure Pa (mmHg) during calculation. e. The sampler was allowed to run for at least 2 minutes to re-establish the run temperature conditions. The pressure drop across the orifice and the well-type manometer reading was recorded during calibration. The variable resistance was adjusted to repeat recording for four different flow rates. f. The best fit straight line was determined by linear regression and the slope (m1), intercept (b1) and correlation coefficient (r) are then determined.
ii. Operating/Analytical Procedure a. The flow rate of the high volume sampler was set to about 1.1 m3/min - 1.7 m3/min prior to commencement of the dust sampling in accordance with the manufacturer's instruction to within the range recommended in USEPA Standard Title 40, CFR Part 50. b. The samplers was located such that: b.1 the filter was about 1.3 meters above ground. b.2 it was greater than 20 meters away from trees. b.3 it was separated from any obstacle by at least twice the height of the obstacle protruding above the sampler. b.4 it has unrestricted airflow 270° around the sampler. c. Fiberglass filters were used for TSP sampling (G810) [Note: these filters have a collection efficiency of > 99% for particles of 0.3 mm diameter. d. All filters were equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment has a temperature setting between 25°C and
4 Route 8 Phase 2a – Nam Wan Tunnel and West Tsing Yi Viaduct Highways Department Monthly EM&A Report – June 2004
30°C and should not vary by more than ±3°C; the relative humidity was < 50% and should not vary by more than ±5%. e. A new filter was placed with stamped number upward on a supporting screen. f. The filter was properly aligned on the screen so that the gasket formed an air-tight seal on the outer edges of the filter. g. Shelter lid closed and catch secured with the aluminum strip. h. The sampler was then allowed to run for at least 5 minutes to establish run- temperature conditions. i. The flow indicator reading was recorded and the sampler flow rate was determined. j. The programmable timer was set and the starting sampling time, weather condition and the filter number was recorded. k. At the end of sampling, the filter was transferred from the filter holder of the HVS to a sealable plastic bag and sent to the laboratory for weighing. The elapsed time was also recorded. l. Before weighing, all filters were equilibrated in a desiccator for 24 hours with temperature of 25°C±3°C and the relative humidity (RH) 50%±5%, preferably 40%.
iii. Maintenance a. The high volume sampler and their accessories were maintained in good working condition, include replacing motor brushes routinely and checking electrical wiring to ensure continuous power supply. b. The high volume samplers were calibrated at bi-monthly intervals using TE-5028A Tisch Environmental Inc. Calibration Kit throughout all stages of the air quality monitoring.

c. time measurement : 30 minutes / 5 minutes
v. Prior to and after each noise measurement, the meter was calibrated using the Calibrator for 94 dB at 1000 Hz. If the difference in the calibration level before and after measurement was more than 1 dB, the measurement would be considered invalid and repeat of noise measurement would be required after re-calibration or repair of the equipment. vi. The wind speed was frequently checked with the portable wind meter. vii. At the end of the monitoring period, the Leq, L90 and L10 were recorded. In addition, site conditions and noise sources were recorded on a standard record sheet. viii. Noise measurement was paused during periods of high intrusive noise if possible and observation was recorded when intrusive noise was not avoided. ix. Noise monitoring was cancelled in the presence of fog, rain, and wind with steady speed exceeding 5 m/s, or wind with gusts exceeding 10m/s.
3.2.6 Maintenance and Calibration i. The microphone head of the sound level meter and calibrator were cleaned with a soft cloth at quarterly intervals. ii. The meter was sent to the supplier to check and calibrate yearly. iii. Calibration certificates are presented in Appendix G4.

7 AUDIT RESULTS
7.1 Air Quality 7.1.1 For 1-hour TSP monitoring, a total of 72 sets of measurements were carried out during the reporting period and all were below the Action/ Limit (AL) Levels. 7.1.2 For 24-hour TSP monitoring, a total of 20 sets of measurements were carried out during the reporting period and all were below the Action/ Limit (AL) Levels.
7.2 Noise
7.2.1 A total of 16 sets of Leq(30min) measurement during daytime (i.e. 0700 to 1900 hours on normal weekdays) were carried out during the reporting period and one exceedance of the Limit Level was recorded at NSR3 on 23rd June 2004. Notification of Exceedance has
10 Route 8 Phase 2a – Nam Wan Tunnel and West Tsing Yi Viaduct Highways Department Monthly EM&A Report – June 2004
subsequently been issued in accordance with Section 9.6 of the EM&A Manual. Investigation was carried out and was concluded that exceedance was not contributed by the Route 8 construction activities and did not have a direct line of sight to the NSRs. Possible exceedance was caused by CT9 activity and local traffic. It should be noted that the newly developed Rambler Crest creates a reflector / barrier effect which enhances the increase in general noise levels at the NSRs and therefore corrective action was not considered necessary.
7.2.2 A total of 16 sets of 6 x Leq(5min) measurement during evening-time (i.e. 1900 to 2300 hours) were carried out during the reporting period and exceedances of the Limit Level were recorded at NSR2 on 23rd June 2004, NSR3 on 4th,11st, 18th, 23rd June 2004. Notifications of Exceedance have subsequently been issued in accordance with Section 9.6 of the EM&A Manual. Investigations indicates that the number of power plants in operation during the monitoring period fully complied with the respective CNP requirements (2 no. rock drills (hand-held), 2 no. air compressors and 1 no. generator) and did not have a direct line of sight to the NSRs. It is therefore unlikely that exceedances were not contributed by the Route 8 construction activities. Possible exceedances were caused by CT9 activity and local traffic. It should be noted that the newly developed Rambler Crest creates a reflector / barrier effect which enhances the increase in general noise levels at the NSRs and therefore corrective action was not considered necessary.
7.2.3 A total of 16 sets of 6 x Leq(5min) measurement during night-time (i.e. 2300 to 0700 hours next day) were carried out during the reporting period and exceedances of the Limit Level were recorded at all locations on 4th,11st June 2004, NSR1-3 on 18th,23rd June 2004. Notifications of Exceedance have subsequently been issued in accordance with Section 9.6 of the EM&A Manual. Investigations indicates that the number of power plants in operation during the monitoring period fully complied with the respective CNP requirements (2 no. rock drills (hand-held), 2 no. air compressors and 1 no. generator) and did not have a direct line of sight to the NSRs. It is therefore unlikely that exceedances were not contributed by the Route 8 construction activities. Possible exceedances were caused by CT9 activity and local traffic. It should be noted that the newly developed Rambler Crest creates a reflector / barrier effect which enhances the increase in general noise levels at the NSRs and therefore corrective action was not considered necessary.
7.2.4 A total of 20 sets of 6 x Leq(5min) measurement during public holiday (i.e. 0700 to 1900 hours) were carried out during the reporting period and exceedances of the Limit Level were recorded at NSR2 on 27th June 2004, NSR3 on 6th, 20th, 27th June 2004.
