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 ® 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.

 4 Route 8 Phase 2a – Nam Wan Tunnel and West Tsing Yi Viaduct Highways Department Monthly EM&A Report – January 2005

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 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.

3.2.5 Monitoring Procedures and Calibration Details Field Monitoring i The microphone of the Sound Level Meter (with weatherproof kit) was mounted on a tripod at a height of 2m above ground level. ii For free field measurement, the meter was positioned away from any nearby reflective surfaces. iii AC power supply was checked to ensure good functioning of the meter. iv Parameters such as frequency weighting, the time weighting and the measurement time were set as follows: a frequency weighting : A b time weighting : Fast 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.

8.2 Summary of Complaints 8.2.1 Two environmental complaints were received during the reporting period and there were of a similar nature but received through different channels. One was received by the Contractor from the Food and Environmental Hygiene Department (FEHD) and the other received by the Highways Department through their complaint hotline on 28th January 2005 and both were

 12 Route 8 Phase 2a – Nam Wan Tunnel and West Tsing Yi Viaduct Highways Department Monthly EM&A Report – January 2005

subsequently passed to the ET in early February 2005. Both complaints were related to the wheel washing facilities at the Exit A of the West Portal Site and conditions of the public road directly outside the Exit. After investigation and separate inspections by FEHD, RSS and the Contractor, it was found that the wheel washing facilities provided at Exit A was adequate. However, significant amount of loose aggregates were found on the public road directly outside Exit A. GSIJV had cleaned up the loose aggregates and increase the frequency of inspection and cleaning up and therefore the complaints are considered closed. A total of 8 no. environmental related complaints have been received for the Project since the commencement of the construction. The summary for all the complaints received since the commencement of the Project is presented in Table 8.2. The details of previous complaints and statistics are attached in Appendices O1 and O2 respectively.

8.3 Summary of Notification of Summon and Prosecution 8.3.1 No notification of summons or prosecutions was received regarding the non-compliance of the environmental performance of the construction site since the commencement of works. 9 FUTURE KEY ISSUES

9.1 Key Issues for the Coming Month 9.1.1 Works to be taken for the coming monitoring period will be similar to the previous month as follows: i Retaining wall construction ii Drainage installation iii Segment mobilization iv Soil nail v Tunnel Works including blasting, concrete lining and rock tipping vi Rock Crushing Plant Operation including rock tipping

9.1.2 Potential environmental impacts arising from the above construction activities are mainly associated with dust, noise, site runoff and waste. However, with the implementation of the following mitigation measures, potential impacts to the surrounding sensitive receivers could be minimized: 9.1.3 Construction Dust i frequently watering of haul road and unpaved areas; ii prohibition of any open burning on site; iii investigation of other dust sources near air sensitive receivers; iv regularly watering or covering of open areas and stockpiles with tarpaulin; v hydroseeding or covering the inactive sand fill area with impervious sheeting if necessary; vi switching off vehicles and equipments while not in use; and vii regular maintenance of onsite machinery and vehicles.

9.1.4 Construction Noise

 13 Route 8 Phase 2a – Nam Wan Tunnel and West Tsing Yi Viaduct Highways Department Monthly EM&A Report – January 2005

i Identification of noise sources arising within and outside worksite; and ii Provision of noise barriers as when necessary.

9.1.5 Construction Runoff i identification of sources of run-off from site; ii provision of sandbags/bunds/channels to direct run-off to silt/sand removal facilities; iii avoidance of direct discharge of wastewater into storm water drainage; and iv provision of treatment of wastewater and run-off prior to discharge.

9.1.6 Construction Waste Management i avoidance of accumulation of construction waste materials and/or general refuse on site; ii segregation of C&D waste; iii collection of chemical waste or oil and disposal of as chemical waste in accordance with the relevant regulations; and iv regularly removing of waste materials on site.

Trip-ticket To monitor the disposal of waste at landfills and control fly-tipping, a ———— system “trip-ticket” system for all solid waste transfer/disposal operations should be implemented. The system should be included as a contractual requirement, and monitored by the Environmental Team and audited by the Independent Environmental Checker.
