Table 1. Air pollutants monitored at Central Queensland sites.

IntroductionAir quality monitoring gathers information on the quality of the air environment. The objectives of the monitoring are to check compliance with ambient air quality guidelines, identify long-term trends in air quality, investigate local air quality concerns and assess the effectiveness of air quality management strategies.

In Central Queensland, air quality monitoring was carried out by the Queensland Government at eight sites in the Gladstone region, and one site in Mackay, Moranbah, Emerald and Blackwater during February 2020.

Air quality bulletin: Central Queensland

Air pollutants monitored included nitrogen oxides, sulfur dioxide, carbon monoxide, ozone, benzene, toluene, total xylenes, formaldehyde, PM10 and PM2.5 (particles with diameters less than 10 µm and 2.5 µm respectively) and visibility-reducing particles. The air pollutants monitored at Central Queenland sites are shown in Table 1. Site locations are shown in Figure 23 at the end of this bulletin.

The monitoring site in central Gladstone (Memorial Park) uses an open-path monitoring method. Pollutant measurements at this site are the average concentration over the light path running from the Gladstone Entertainment Centre to Memorial Park (see Figure 23).

The monitoring site at Fisherman’s Landing was established in March 2016 to measure the impact of any emissions from LNG facilities situated on Curtis Island. The site is located on industrial land and, as such, measured pollutant levels do not reflect typical population exposure in the Gladstone region.

The monitoring site at Blackwater was established in February 2019 to assess the impact of coal mining operations on the community. The Emerald site was established in February 2020 to obtain information on particle levels in an inland community not impacted by mining activities.

Reporting protocolData presented in this bulletin are based on clock hours. Hourly or other averages are constrained to start and finish on a clock hour.

Air quality summary graphsFigures 1 to 22 summarise available air quality data for each day of February. Only the maximum recorded level for each day is used to show the day-to-day variation in air quality.

Air quality summary tablesTables 4 to 17 present monthly summaries of air quality data for the preceding 12 months. These tables show the month-to-month variation in air quality. A monthly entry is given when at least three-fifths of the maximum possible number of observations during the month are available. When data is not available for the entire month, due to equipment malfunction or other reason, this is indicated by the abbreviation ‘n.d.’ (no data). A dash is inserted when less than three-fifths of the data are available. Where no data is recorded, the reason for the low data availability is summarised in Table 18 at the end of this bulletin.

GuidelinesAir quality measurements are compared against air quality standards contained in the Queensland Government Environmental Protection (Air) Policy 2019 (EPP (Air)) to assess whether pollutant levels could harm health and well being. The EPP (Air) visibility objective is used to assess the impact of visibility-reducing particles on visual air quality. The relevant guidelines are shown in the air quality summary table for each pollutant.

In October 2019 the Moranbah and West Mackay monitoring sites were upgraded to measure PM2.5 in addition to PM10. Dustfall monitoring commenced at

Moranbah in February 2020.

Compliance with air quality guidelines - GladstoneDuring February, measured pollutant levels, with the exception of PM10, PM2.5 and visibility-reducing particles, did not exceed the relevant EPP (Air) air quality objective at the Queensland Government air monitoring sites in the Gladstone region.

Table 2. Number of occasions during February 2020 when measured levels exceeded EPP (Air) objectives for nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, benzene, toluene, xylenes, formaldehyde, visibility-reducing particles, PM10 and PM2.5 at the Queensland Government air monitoring sites in Gladstone.

Smoke from hazard reduction burns carried out in the Curtis Island National Park caused visibility to fall below the EPP (Air) 1-hour objective of 20km at the Targinie (8 hours in total), Fisherman's Landing (8 hours in total) and Boat Creek (7 hours in total) monitoring sites between 20 February and 21 February, and a one hour period at the Clinton monitoring site on 21 February. The smoke also led to an exceedance of the EPP (Air) 24-hour PM2.5 objective at the Targinie monitoring site on 20 February, and contributed to an exceedance of the EPP (Air) 24-hour PM10 objective at the Fisherman's Landing monitoring site on the same day.

Over the 12-month period ending February 2020, the EPP (Air) annual average PM10 standard was exceeded at the Fisherman's Landing site. This was predominantly due to activities taking place within the industrial area where the Fisherman's Landing monitoring site is located, in particular dust generated by vehicle movements on unsealed roads. Significantly lower 12-month PM10 concentrations at the nearby Boat Creek and Targinie monitoring sites indicate that the elevated dust levels were restricted to the industrial area.

The EPP (Air) annual average PM2.5 standard was exceeded at the Clinton, Boat Creek and Fisherman's Landing monitoring sites over the 12-month period ending February 2020. This was a result of PM2.5 emissions from local sources such as industry, motor vehicles and aircraft, coupled with added emissions from occasional but significant regional PM2.5 events such as dust storms and bushfire smoke.

During February, measured pollutant levels did not exceed the relevant EPP (Air) air quality objective at the Queensland Government air monitoring sites in Mackay, Emerald and Blackwater.

The EPP (Air) annual average PM10 objective was exceeded at the Moranbah monitoring site over the 12-month period ending February 2020 due to a range of emission sources including dust storms, windblown surface dust, local activities generating dust and bushfires, with the very dry conditions exacerbating these emissions.

The Department of Environment and Heritage Protection Air Impacts Guideline recommends a dust deposition limit of 120 mg/m2/day, averaged over one month, be used to assess dust nuisance.

There is a minimum dust deposition rate that can be determined with the sampling equipment and laboratory method used. Dust deposition rates below this minimum reporting value are preceded by a "<" sign in this table.
