Introduction

Air quality readings above the goal were recorded on 21 October 2013 at all of the monitoring stations. These readings related to PM10 greater than the ambient 24-hr average

goal of 50 µg/m3.

Assessment of the incident has shown that the incident was the result of the recent Sydney wide bush fire event.

Incident 21 October 2010 – PM10

Readings above the 24-hour average PM10 air quality goal were recorded at the M5 East Freeway air quality monitoring stations on 21 October 2013. Details of the validated and unvalidated results for the period are shown in Table 1 below. (Daily unvalidated data on the RMS Website is in Appendix 1).

Appendix 1 shows the daily unvalidated data for four monitoring stations on 21 October 2013 and Appendix 2 shows the alarm email sent through as notification of the exceedance. In accordance with the requirements of the M5 East Tunnel DUAP Condition 73/4 Protocol, the air quality reading above the goal at the M5 East monitoring station was found to have been caused by the recent bush fire smoke.

Assessment vs 73/4 protocol

The following actions have been carried out in accordance with the M5 East Freeway DUAP Condition 73/4 Protocol:

1. Planning NSW and EPA were notified by e-mail within one day of the monitoring indicating that a readings above the goal of the 24 hour PM10 air quality goal had occurred; (refer to Appendix 2)

2. Quality validation of the data was undertaken confirming that the TEOM 24 hour average readings were above the 50 µg/m3 ambient air quality goal for fine particulates (PM10) at ground level; (See Appendix 1)

3. Information was obtained from The Office of Environment and Heritage (OEH) air quality monitoring sites in the Sydney Basin via the OEH website to determine whether the readings above the goal were caused by a Sydney wide event. The OEH monitored results and published data confirmed that a regional event on the day (bush fires) had an adverse impact on air quality (See Appendix 4). Media warnings also confirmed the conditions (see Appendix 5).

4. On obtaining confirmation that an extraordinary event had occurred, an assessment report was prepared and submitted to Planning NSW and EPA.

Clearance reports for the stations F1, X1, T1, M1,CBMS and U1 have been received for

the stations today 22/10/2013.

Containment:

High levels of smoke were out of the control of the project and have been logged as an

extraordinary event

Clean-up information:

N/A

Other details (if any):

In regards to the exceedences this is not an exceedence that has been caused by the

project. The extraordinary events of the bushfires surrounding Sydney are believed to have

caused this event due to the smoke and particulate matter that has blown over the city.

The Office of Environment and Heritage's air quality monitoring stations also recorded to

have exceeded the PM10 24 hour average of 50migrograms/m3, the nearest station to the

the M5 East at Earlwood read at 63.1 micrograms/m3 (please see link below) and health

alerts for air pollution have also been issued by the Ministry of Health for the Sydney

region

http://www.environment.nsw.gov.au/AQMS/dailydata.htm

Forecast for the next couple of days also suggest that levels may exceed once again.
