3.                      Monitoring Results

3.1                   Impact Monitoring Schedule

3.1.1              Regular site inspections were carried out on 3, 8, 17, 24 and 31 Jan 2008 in this reporting month to assess the compliance with environmental requirements. The EM&A schedule is given in Appendix D.

3.1.2              However, no air quality monitoring was conducted because of insignificant site works undertaken during this reporting month.

3.2                   Monitoring Methodology

24-hour TSP Monitoring

Installation

3.2.1              The HVS has been installed close to representative air sensitive receivers.  The following criteria have been considered in the installation of the HVS.

·          A horizontal platform with appropriate support to secure the sampler against gusty wind was provided.

·          The distance between the HVS and any obstacles, such as buildings, was at least twice the height that the obstacle protrudes above the HVS.

·          A minimum of 2m separation from walls, parapets and penthouse was required for rooftop sampler.

·          No furnace or incinerator flues were nearby.

·          Airflow around the sampler was unrestricted.

·          Permission was obtained to set up the samplers and to obtain access to the monitoring stations.

·          A secured supply of electricity is needed to operate the samplers.

Preparation of Filter Papers

·         Glass fibre filters, G810 are to be labelled with sufficient filters that are clean and without pinholes.

·         All filters are to be equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment temperature is to be around 25 °C and not variable by more than ±3°C, the relative humidity (RH) is to be < 50% and not variable by more than ±5 %.  A convenient working RH is 40%.

Field Monitoring

·         The power supply is to be secured to ensure the HVS works properly.

·         The filter holder and the area surrounding the filter are to be cleaned.

·         The filter holder is to be removed by loosening the 4 bolts and a new filter, with stamped number upward, on a supporting screen to be aligned carefully.

·         The filter is to be properly aligned on the screen so that the gasket forms an airtight seal on the outer edges of the filter.

·         The swing bolts are to be fastened to hold the filter holder down to the frame.  The pressure applied is to sufficient to avoid air leakage at the edges.

·         The shelter lid is then closed and is secured with the aluminium strip.

·         The HVS shall be warmed-up for about 5 minutes to establish run-temperature conditions.

·         A new flow rate record sheet is to be set into the flow recorder.

·         The flow rate of the HVS is to be checked and adjusted at around 1.1 m3/min.  The range specified in the updated EM&A Manual is between 0.6-1.7 m3/min.

·         The programmable timer is set for a sampling period of 24 hrs + 1 hr, and the starting time, weather condition and the filter number are to be recorded.

·         The initial elapsed time is to be recorded.

·         At the end of sampling, the sampled filter is to be removed carefully and folded in half length so that only surfaces with collected particulate matter are in contact.

·         It was then placed in a clean plastic envelope and sealed.

·         All monitoring information is to be recorded on a standard data sheet.

·         Filters are to be sent to a HOKLAS accredited laboratory for analysis.

Maintenance and Calibration

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

·         HVSs are to be calibrated at a bi-monthly intervals using GMW-25 Calibration Kit throughout all stages of the air quality monitoring.

1-hour TSP Monitoring

Field Monitoring

3.2.2              The measuring procedures of the 1-hour dust meter are to be in accordance with the Manufacturer’s Instruction Manual as follows:

·         Set POWER to “ON”, push BATTERY button, make sure that the meter’s indicator is in the range with a red line and allow the instrument to stand for about 3 minutes (Then, the air sampling inlet has been capped).

·         Push the knob at MEASURE position.

·         Push “O-ADJ” button. (Then meter’s indication is 0).

·         Push the knob at SENSI ADJ position and set the meter’s indication to S value described on the Test Report using the trimmer for SENSI ADJ.

·         Pull out the knob and return it to MEASURE position.

·         Push “START” button.

Maintenance and Calibration

·         The 1-hour TSP meter would be checked at 3-month intervals and calibrated at 1-year intervals throughout all stages of the air quality baseline monitoring.

3.2.3              However, no dust monitoring was carried out because of absence of dusty activities. As per the approved EM&A Manual, dust monitoring stations are located as shown in Figure 2.1.
