4                 AIR QUALITY MONITORING

4.1              Monitoring Requirement

4.1.1          In accordance with the Updated EM&A Manual, 1-hr and 24-hr total suspended particulate (TSP) levels at the designated air quality monitoring station are required.  Impact 24-hour TSP monitoring should be carried out for at least once every 6 days.  For the 1-hr TSP impact monitoring, the sampling frequency of at least three times in every 6 days should be undertaken when the highest dust impact occurs.

4.2              Monitoring Equipment

4.2.1          The 1hr- TSP and 24-hr TSP air quality monitoring were performed using a High Volume Sampler (HVS), of which its location and operation satisfy, as far as practicable, all the requirements as specified in the Updated EM&A Manual.  The brand and model of the equipment are given in Table 4.1.

4.2.2          The HVS and its accessories were maintained in good working condition, such as replacing motor brushes routinely and checking electrical wiring to ensure a continuous power supply.

4.2.3          Calibration of the HVS (five point calibration) using Calibration Kit was carried out every two months.  The HVS calibration orifice will be calibrated annually.  Calibration certificate of the TE-5025A Calibration Kit and the HVS are provided in Appendix C.

4.2.4          The electricity supply of HVS at AM1(SR77) was suspended from 16 May 2019 and was no longer available. In order to have a more secure electricity supply, an alternative Handheld TSP meter was proposed to use for the temporary monitoring  of 24-hr & 1hr air quality from 22 May 2019. In this regard, IEC and ER have no adverse comment on it. And Calibration certificates of the Handheld TSP meter are provided in Appendix C.

4.3              Monitoring Location

4.3.1          Air quality monitoring was conducted at the location specified in the Updated EM&A Manual.  Table 4.2 describes the details of the air quality monitoring station with its location as shown in Figure 2.

4.5              Monitoring Methodology

1-hr and 24-hr TSP Monitoring

4.5.1          With the consideration of criteria stated in the Updated EM&A Manual, the HVS was installed in the vicinity of the air sensitive receivers.

4.5.2          The relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, and any special phenomena observed were recorded.  The weather information was referenced from Hong Kong Observatory (http://www.weather.gov.hk/wxinfo/pastwx/extractc.htm).

4.5.3          A HOKLAS accredited laboratory with constant temperature and humidity control, and equipped with necessary measuring and conditioning instruments, to handle the 24-hr TSP samples, was employed for sample analysis.

4.5.4          Filter papers of size 8"x10" were labelled before sampling.  They were inspected to be clean with no pin holes and conditioned in a humidity controlled chamber for over 24-hr and were pre-weighed before use for the sampling.

4.5.5          The 24-hr TSP levels were measured by following the standard high volume sampling method for TSP as set out in the Title 40 of the United States Code of Federal Regulations, Chapter 1 (Part 50), Appendix B.  TSP was sampled by drawing air through a conditioned, pre-weighted filter paper inside the HVS at a controlled air flow rate.  After 24-hr sampling, the filter papers loaded with dust were kept in a clean and tightly sealed plastic bag, and then returned to the laboratory for reconditioning in the humidity controlled chamber followed by accurate weighing by an electronic balance with a readout down to 0.1 mg.

4.5.6          All the collected samples were kept in a good condition for 6 months before disposal.

4.5.7          For 1-hr TSP monitoring, monitoring methodology is the same as 24-hr TSP monitoring which has been presented in Section 4.5.1 to Section 4.5.6, but with sampling period changed to 1 hour.

4.6              Monitoring Schedule for the Reporting month

4.6.1          As informed by the contractor, all major construction activities of the Entrusted Portion Project of Section 1A and 1B were substantially completed on 28 September 2018 and 3 October 2018 respectively. In such regard, the EM&A Programme of the captioned project, including monthly EM&A reporting and the corresponding environmental monitoring and audit works, is no longer required and we proposed to cease it by the end of December 2018 and we have submitted the termination proposal to EPD on 24 December 2018. And EPD are replied the EM&A monitoring shall only be terminated when insignificant environmental impacts of the remaining outstanding construction works are expected and agreement of EPD. After that we have submitted the termination proposal to EPD on 4 April 2019 again. EPD replied we need to provide the Final EM&A Report to facilitate their consideration for the termination on 14 May 2019. Therefore, the EM&A monitoring and audit works will be ceased upon EPD¡¦s approval for the termination proposal is approved.  The tentative schedule for environmental monitoring for the reporting month is provided in Appendix D. 

4.6.2          Meteorological data extracted from Hong Kong Observatory for the reporting month is provided in Appendix E.

At least once per week

 

5.5              Monitoring Methodology

5.5.1          The monitoring procedures are summarised as follows:

¡P            The sound level meter was set on a tripod at a height of 1.2 m above the ground for free-field measurements at monitoring station SR77;

¡P            The battery condition was checked to ensure good functioning of the meter;

¡P            Parameters such as frequency weighting, the time weighting and the measurement time were set as follows:

¡P            Frequency weighting: A

¡P            Time weighting: Fast

¡P            Parameters: Leq, L10 and L90

¡P            Time measurement: Leq(30-minutes) during non-restricted hours i.e. 07:00 ¡V 19:00 hrs on normal weekdays

¡P            Prior to and after each noise measurement, the meter was calibrated using the acoustic calibrator for 94dB(A) at 1000 Hz.  If the difference in the calibration level before and after measurement was more than 1dB(A), the measurement would be considered invalid and repeat of noise measurement would be required after re-calibration or repair of the equipment.

¡P            At the end of the monitoring period, the Leq, L10 and L90 were recorded.  In addition, site conditions and noise sources were recorded on a standard record sheet.

¡P            A façade correction of +3dB (A) shall be made to the noise parameter obtained by free field measurement.
