Air Quality
3.1.1. The impact monitoring had been carried out in accordance with section 5.8 of the approved EM&A Manual to determine the 1-hour and 24-hour total suspended particulates (TSP) levels at the monitoring locations in the reporting month.
3.1.2. The sampling frequency of at least once in every 6 days, shall be strictly observed at the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring, the sampling frequency of at least 3 times in every 6 days should be undertaken when the highest dust impact occurs.
3.1.3. General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources had also been recorded throughout the impact monitoring period.
Air Quality
3.2.1. 1-hour TSP levels and 24-hour TSP had been measured with direct reading dust meter and High Volume Samplers respectively. It has been demonstrated its capability in achieving comparable results with high volume sampling method as set out in the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50).
3.2.2. The 1-hour TSP meter was calibrated by the manufacturer prior to purchasing. Zero response of the instrument was checked before and after each monitoring event. Operation of the 1-hour TSP meter followed manufacturer’s Operation and Service Manual. The 24-hour TSP meter was calibrated against firmware 80570-8100-V1.0.4, annually. Operation of the 24-hour TSP meter followed manufacturer’s Operation and Service Manual. Valid calibration certificate of dust monitoring equipment is attached in Appendix G.
3.2.3. A summary of the equipment that was deployed for the 24- hour averaged monitoring is shown in Table 3.1. The TSP monitoring was conducted as per the schedule presented in Appendix F.
3.2.4. The equipment used for 1-hour TSP and 24-hour TSP measurement and calibration are summarised in Table 3.1

3.3. Monitoring Methodology and QA/QC results
Air Quality
3.3.1. The 1-hour TSP monitor, portable dust meters (Sibata Digital Dust Indicator Model LD-5R) was used for the impact monitoring. The 1-hour TSP meters provides a real time 1-hour TSP measurement based on 90o light scattering. Three 1-hour TSP level were logged per every six days.
3.3.2. The 24-hour TSP monitor, High Volume Samplers (Tisch TE-5170x High Volume Air Sampler) were used for the impact monitoring. The 24-hour TSP monitoring consists of the following:
u The HVS was set at the monitoring location, with electricity supply connected and secured;
u HVS was calibrated before commencing the 1st measurement;
u The filter paper was weight and provided by HOKLAS lab (Acumen Laboratory and Testing Limited and ALS Technichem (HK) Pty Ltd) before and after the sampling. Certificate of HOKLAS accredited laboratory can be referred to Appendix H;
u The airflow over time during sampling process was recorded by the HVS.
3.3.3. HVSs were free-standing with no obstruction. The following criteria were considered in the installation of the HVS:
u Appropriate support to secure the samples against gusty wind needed to be provided the monitoring station;
u A minimum of 2m separation from walls, parapets and penthouses was required for rooftop samplers;
u No furnace or incinerator flues was nearby;
u Airflow around the sampler was unrestricted; and
u Permission could be obtained to set up the samplers and gain access to the monitoring station.
u Any wire fence and gate, to protect the sampler, should not cause any obstruction during monitoring
u A secured supply of electricity is needed to operate the samplers.
3.3.4. Preparation of Filter Papers
u Glass fiber filters were labelled and sufficient filters that were clean and without pinholes were selected;
u All filters were equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment temperature was around 25℃ and not varied by more than ±3℃; the relative humidity (RH)was 40%; and
u Acumen Laboratory and Testing Limited and ALS Technichem (HK) Pty Limited, as HOKLAS accredited laboratory, implemented comprehensive quality assurance and quality control programmes on the filters.
u The power supply was checked to ensure that the HVS was working properly;
u The filter holder and area surrounding the filter were cleaned;
u The filter holder was removed by loosening the foul bolts and a new filter, with stamped number upward, on a supporting screen was aligned carefully;
u The filter was properly aligned on the screen so that the gasket formed an airtight seal on the outer edges of the filter;
u The swing bolts were fastened to hold the filter holder down to the frame. The pressure applied should be sufficient to avoid air leakage at the edges;
u The shelter lid was closed and secured with an aluminum strip;
u The HVS was warmed- up for about 5 minutes to establish run- temperature conditions;
u A new flow rate record sheet was inserted into the flow recorder;
u The flow rates of the HVS was checked and adjusted to between 1.22-1.37 młminł, which was within the range specified in the EM&A Manual (i.e. 0.6- 1.7 młminł);
u The programmable timer was set for a sampling period of 24 hours ±hour, and the starting time, weather condition and filter number were recorded;
u The initial elapsed time was recorded;
u At the end of sampling, the sampled filter was removed carefully and folded in half so that only surfaces with collected particulate matter were in contact;
u The filter paper was placed in a clean plastic envelope and sealed; all monitoring information was recorded on a standard data sheet and
u The filters were sent to (Acumen Laboratory and Testing Ltd and ALS Technichem (HK) Pty Ltd) for analysis.
3.3.6. Maintenance and Calibration
u The HVS and their accessories were maintained in a good working condition. For example, motor brushes were replaced routinely and electrical wiring was checked to ensure a continuous power supply; and
u The flow rate of each HVS with mass flow controller was calibrated using an orifice calibrator, Initial calibrations of the dust monitoring equipment were conducted upon installation and prior to commissioning. Five- point calibration was carried out for HVS using TE-5028A Calibration Kit. HVS is calibrated in fortnightly Intervals. The calibration records for the HVS is given in Appendix G.
u The wind speed has been recorded from Hong Kong Observatory- King’s Park meteorological station, along with portable wind speed meter stand by as back up if malfunction occurred or data was not recorded from HKO
