Existing Air quality Monitoring Data near the Proposed Stacks

Before construction on the New M5 started, there was an air quality monitoring program to get some air quality baseline figures for the proposed stacks. Most of the monitoring stations have been decommissioned.

In all the tables with pollution figures, I highlighted everything of concern. I am using the national air quality standard as a yardstick of whether we should be concerned or not. This standard is also reflected in the approval conditions. I am using the following conventions for highlighting reasons for concern:

Monthly average is higher than yearly target average For any one month, such an occurrence is NOT a breach of the national air quality standard (unless the level is so extreme that the monthly average also breaches the 24 hour target). But a pattern of such occurrences can lead us to conclude that the yearly target has also been breached.
Exceedance

For yearly targets, this is based on the available monthly data. We don't always have a full 12 months. And in any case, looking at the reports, there are often quite a few days missing within months. But the pattern of high monthly figures is often such that it is obvious that the yearly target was also exceeded.

For daily exceedances, I have gone through the reports to see what reason was given. In some cases, the reports speculate on regional events without saying what the event was, based on higher readings at multiple sites. I am still counting those exceedances as genuine, because the regional event could have been adverse weather in which road-based pollutants do not disperse as readily as on other days. That would still amount to road-based pollution causing the exceedance. I am counting road construction (only applicable to St Peters) as road-based pollution.

Probable Exceedance For yearly targets, where the monthly data don't cover a whole year, the average of those months is over the yearly target average but not by enough to say that the exceedance of the yearly target is obvious.
Excused Exceedance This covers exceedances that are explained by non-road sources. In all cases, this was hazard reduction burning or bush fire.
No reason given for exceedance nor required to be given The approval conditions exempt the project from meeting national air quality targets during construction and do not require explanations for exceedances. And no explanation appeared in the reports. This category covers such exceedances.

St Peters

Monitoring at St Peters Public School

The air quality monitoring station at St Peters has been continuously operating since 2015, is still operating and will be operating for at least two years after the New M5 opens. It is a monitoring station in addition to the ones for which we are discussing locations at the AQCCC.

Month PM2.5 monthly average, μg/m3 (yearly allowed average is 8) PM2.5 highest 24 hours period, μg/m3 (allowed is 25) PM10 monthly average, μg/m3 (yearly allowed average is 25) PM10 highest 24 hours period, μg/m3 (allowed is 50) Highest CO rolling 8 hour average, ppm (allowed is 9) Highest NO2 hourly average, ppb (allowed is 120)
July, 2015 The report states: "There is no reporting data for the St Peters Public School monitoring site since the site was only commissioned on 14 July 2015, part way into this reporting period."

About the 28/6/2017 exceedance which is possibly due to wood fired heaters: Other sites only reported moderately elevated levels (according to the report) while at St Peters we had nearly double. I actually had a look at the other sites in the same report. They were well within limits. In the case of Rozelle, less than half the limit. So I am counting the St Peter PS exceedance as genuine.

The explanation of the March 2018 exceedances in the report were a little incoherent. I made sense of what was there as best as I could.

According to the February, 2016, New M5 Air Quality Report, The minimum 24 hours reading for PM2.5 was -1.1 μg/m3. Obviously, air can't contain a negative amount of particles. So, clearly the West Botany Street monitoring station was defective. I assume that some of the other, if not all, PM2.5 readings are also below actual pollution. Unfortunately, I could not find an explanation in the report. The January, 2016, report states a 0.0 minimum reading but the graph actually drops below zero as well.
