Statistical analysis of the data should be consistent with (2) above. Monitoring is to be conducted for a minimum of 12 months to cover seasonal changes across the warmer and cooler months or longer if variability in climatic conditions or industrial emissions is of concern. Site selection, instrumentation and sample analysis are to be conducted using methods outlined in the Department of Environment and Heritage Protection or relevant updated Australian Standards. (3) In the absence of suitable publicly available monitoring data, site-specific ambient monitoring data can be used. The use of numerical meteorological model data as input to CALMET is discussed further in of this planning scheme policy.ĥ.3.1 Existing background air quality. The CALMET data files are to be representative of the location, following the data selection and analysis methodologies outlined in of this planning scheme policy. CALPUFF is not to be used where single-point meteorological data, such as an AUSPLUME-compatible data file, is used. (3) The most recent official version of is to be used to generate three-dimensional meteorological data files for CALPUFF. The measurement sample size, operating conditions (including feedstock type, rate and volume and production rate) and range of measurement results are to be stated. All sampling of source emissions and analysis of air pollutants is to be in accordance with the DEHP or current versions of Australian Standard methods. (c) site-specific historical and current emissions measurement data for existing sources may be used to determine emission rates, emission concentrations and source release parameters.
