UPPER HUNTER DUST MONITORING 1-NOV-2012 21:00
Muswellbrook - Air Quality Alert At Thu 01/11/12 19:00 PM10 exceeded national health standards.
Health Alert. Singleton South air pollution exceeded national health standards for PM10 at Thu 01/11/12 19:00.
[System Message: A false hourly PM10 reading of 1545 ug/m3 at Camberwell at 8pm on 1st November has been invalidated. This false reading was caused by a malfunction in the PM10 TEOM instrument following the resumption of power after a power outage at the site. Only data for this hour at this site was affected. OEH apologises for the technical problem /b]

[MOUNT THORLEY MONITOR: UNEXPLAINED NIGHTLY DUST LOAD PEAKS

We have known for some time that the Hunter dust loads often increase during the night when there is little or no wind. The following three examples of the archived data patterns extracted from the Upper Hunter Air Quality Monitoring system illustrate the situation. You can study these events in further details by going to
http://forum.huntervalleyprotectionalliance.com/viewforum.php?f=12&start=25
and displaying data for the day indicated. More similar data patterns can be found in the archives.


DateTime PM10 Wind km/h Wind Dir
03/09/2012 23:00 290.8 3.0 163.88
03/09/2012 24:00 182.5 0.8 193.82
04/09/2012 01:00 165.6 0.7 172.11
04/09/2012 02:00 151.5 2.8 180.15
04/09/2012 03:00 146.5 3.4 8.02

Date Time PM10 Wind km/h Wind Dir
11/09/2012 01:00 107.5 2.7 166.82
11/09/2012 02:00 143.7 1.0 167.25
11/09/2012 03:00 224.9 0.8 39.85
11/09/2012 04:00 244.4 2.2 169.52
11/09/2012 05:00 183.2 0.9 345.02
11/09/2012 06:00 203.0 0.7 238.77
11/09/2012 07:00 108.3 7.4 165.71

Date Time PM10 Wind km/h Wind Dir
03/10/2012 22:00 78.7 0.8 97.26
03/10/2012 23:00 109.4 2.4 197.19
03/10/2012 24:00 218.5 3.3 203.77
04/10/2012 01:00 173.4 1.6 198.65
04/10/2012 02:00 132.8 0.7 260.13
04/10/2012 03:00 75.1 1.6 194.35
04/10/2012 04:00 126.4 1.3 193.68
04/10/2012 05:00 94.8 0.5 250.81
04/10/2012 06:00 63.8 5.3 339.30
04/10/2012 07:00 51.8 9.0 351.75


Dust load peaks in the above events cannot be explained by the effect of wind because the recorded wind speeds were extremely low - well below 5 km/hour. Since there are no other major sources of the air dust pollution in the Valley, this must have been due to mining activities in the surrounding open cuts. It would be interesting to compare these date with the work logs of the three mines.

All Hunter Valley coal mines claim that they run a thorough internal dust monitoring systems. Unfortunately, they do not share real time dust data with the local community .
Rio Tinto Warkworth/Mt.Thorley Mine provides little of the relevant environmental information on their website:
http://www.riotintocoalaustralia.com.au/ouroperations/3453_mount_thorley_warkworth_3588.asp
Xstrata Bulga Mine http://www.bulgacoal.com.au/EN/Publications/Pages/EnvironmentalMonitoringReports.aspx provides some comprehensive environmental reports based on averages of averages that essentially hide any dust load peak events . However, Xstrata does a far better job here. It would be very useful if all mines were forced to provide dust monitoring data online. Existence of such a system would prevent mines blaming each other for the air dust pollution.
