This is the interim report for the work undertaken for the Strategic Regional Environmental and Baseline Assessment (SREBA) Environmental Health Air Quality baseline study. The Air Quality baseline is a 12 month monitoring program to measure key air pollutants and meteorological parameters from five air quality monitoring stations were set up within the study area at Manbulloo, Mataranka, Bullwaddy Conservation Reserve, Daly Waters and Elliott. Pollutants measured were selected based on the expected emissions from onshore gas development, and include particulate matter (PM), both suspended particles and deposited dust, and gases (NO2, SO2, H2S, VOCs and aldehydes). The interim report summarises the initial data (~2 months) collected by the air quality monitoring program and outline monitoring methods for each pollutant including details of quality control procedures undertaken. The sample of data collected is not yet sufficient to draw reliable conclusions regarding the baseline air quality in the region. The baseline monitoring program is scheduled to continue for a further 10 months, with a total of 12 months of data collected at the completion. Some recommendations are provided in the report regarding ongoing monitoring, which are to be reassessed at the completion of the 12 month monitoring program.

Monitoring results The monitoring period began in late September 2022 and this section provides results for the data available to date. 5.1 Dust deposition gauges Dust deposition sampling is being carried out with a sampling interval of approximately one month. It should be noted that due to the remote nature of the sampling locations, and associated access restrictions, that sampling periods are not strictly in compliance with the standard sampling period (302 days) as outlined in AS/NZS 3580.10.1:2003. It is not expected that this deviation from the standard would have any significant implications for the assessment. The assessment of the DDG results is a daily rate on a monthly average basis, rather than against a total mass over a month-long period. The DDG results are presented as the monthly average deposition rate in g/m/month. No criteria are stipulated by the NEPM for deposited dust, however, many state guidance provide a limit of 4 g/m/month. The results of dust deposition sampling for the first month of monitoring are presented in Table 5.1. The results show that the dust deposition rates are within the adopted objective level.
