Monitoring Equipment and Methods3.2 Ambient AirContinuous monitoring of ambient air quality is carried out at sites P1, P2, P3 and P4 forTotal Suspended Particulates (TSP) using the TEOM 1405 TSP Ambient ParticulateMonitor. The TEOM passes a known volume of air through a filter, and records the mass ofparticulate matter collected by the filter. The concentration of TSP is then calculated bydividing the mass of particulate matter by the volume of air sampled.3.3 Dust DepositionDust deposition gauges are installed at all sites listed in Table 3-1 to examine the amountof dust deposition (fallout) that is occurring around the Port. Sample bottles are collectedon a monthly basis and analysed by an ALS NATA accredited laboratory for soluble solids,insoluble solids, combustible matter and approximate percentage of fine dark particles.3.4 NoiseFour Class 1 Bruel & Kjaer 2250 Sound Level Meters fitted with outdoor microphone kitsmonitor sound levels continuously at sites P1, P2, P3 and P4. Sound levels are monitoredover integration periods of 15 min, 1 hour and 24-hours for statistical values of LA90 , LA1,LA5, LA10, LA50, LA95, LA99. In addition, the LAeq , minLpA, maxLpA and Z-weighted one-thirdoctave band sound levels from 12.5 Hz to 20,000 Hz are also recorded.Data collected by this equipment is sent for technical review and analysis by PrincipalConsultant W Les Huson of L Huson & Associates Pty Ltd.3.5 Meteorological ConditionsMeteorological conditions are monitored on a continuous basis at sites P1, P2, P3 and P4using a Vaisala WXT520 Multisensor Weather Monitor. Conditions monitored include windspeed and direction, ambient temperature and relative humidity.The Equipment Maintenance Register in Appendix B indicates the maintenance that wascarried out on monitoring equipment by ALS staff in January 2012.4 Results4.1 Meteorological Monitoring4.1.1 Wind Speed and DirectionWind speed and direction from sites P1, P2, and P4 are outlined in Figures 1, 2 and 3below. The wind sensors at P3 were removed on 12 th March 2010 and moved to P4 due torust on the probes at P4. New probes have now been installed at P3 and Ergon Energy hasbeen approached to restore power to the site.EE2012-015Hay Point Coal Terminal & Dalrymple Bay Coal TerminalFinal January 201210
Figures 1, 2 and 3 show winds in the Port of Hay Point and Dalrymple Bay originating froma predominantly East to South Easterly direction during the month of January 2012. P1saw an average wind speed of 2.48m/s with a maximum velocity of 7.44m/s beingrecorded during the month.Figure 1: Wind Speed and Direction at P1 for January 2012An average wind speed of 1.60m/s and a maximum of 6.33m/s were recorded at P2 thismonth.Figure 2: Wind Speed and Direction at P2 for January 2012EE2012-015Hay Point Coal Terminal & Dalrymple Bay Coal TerminalFinal January 201211
