15 Compliance with Standards Unless stated below, parameters are monitored at the Network according to the methods detailed in Table 4. The siting of external ambient monitoring stations does not comply fully with AS/NZS :2007 due to the proximity of nearby trees. Measurement of solar radiation at Centenary Pool (E2) does not comply with AS/NZS and is not covered by Ecotech s NATA scope of accreditation due to overdue calibration. Data for the entire month is for reference only. Airgas cylinder used at Anzac Park (W1) is non compliant with NATA traceability requirements Data Acquisition Data acquisition is performed using a PC based WinAQMS logger (using WinAQMS Version 2.0) situated at each of the monitoring sites. Each logger is equipped with a 3G modem for remote data collection. The recorded data is remotely collected from the AQMS loggers on a daily basis (using AirodisTM version 5.1.0) and stored at Ecotech s Environmental Reporting Services (ERS) department in Melbourne, Australia. Data samples are logged in 5 minute intervals, expect for beta attenuation monitor dust parameters which are logged in 1 hour intervals Data Validation and Reporting Validation The Ecotech ERS department performs daily data checks to ensure maximum data capture rates are maintained. Any equipment failures are communicated to the responsible field engineers for urgent rectification. Ecotech ERS maintains two distinct databases containing non-validated and validated data respectively. The validated database is created by duplicating the non-validated database and then flagging data affected by instrument faults, calibrations and other maintenance activities. The data validation software requires the analyst to supply a valid reason (e.g. backed by maintenance notes, calibration sheets etc) in the database for flagging any data as invalid. Details of all invalid or missing data are recorded in the Valid Data Exception Tables. Validation is performed by the analyst, and the validation is reviewed. Graphs and tables are generated based on the validated five minute and one hour data. Page 15 of 65

16 Reporting Data is reported separately in a Microsoft Excel format file(s) named Legacy Way Monthly Data Report_August 2016.xls and Legacy Way Monthly Met Data Report_August 2016.xls. The Legacy Way Monthly Data Report_August 2016 Excel file consists of nine worksheets: 1. Cover 2. 5 Minute Data 3. 1 Hour Data 4. 1 Day Data 5. CO 8hr Rolling 6. Span 7. Zero 8. Precision 9. Valid Data Exception Report The Legacy Way Monthly Met Data Report_August 2016 Excel file consists of five worksheets: 1. Cover 2. 5 Minute Data 3. 1 Hour Data 4. 1 Day Data 5. Valid Data Exception Report The data contained in this report is based on Australian Eastern Standard Time. All averages are calculated from the five minute data, except dust parameters from BAM1020 instruments which are calculated from one hour data. Averages are based on a minimum of 75% valid readings within the averaging period. As the Fidas 200 instrument records mass concentrations values in µg/m³ referenced to the local ambient temperature and pressure, the PM 10 data is corrected to Australian STP. Averaging periods of eight hours or less are reported for the end of the period, i.e. the hourly average 02:00am is for the data collected from 1:00am to 2:00am. One hour averages are calculated based on a clock hour. One day averages are calculated based on calendar days. Page 16 of 65

25 5.0 Results 5.1. Data Capture Data capture is based on 5 minute data, except for BAM1020 dust parameters which are based on hourly values, and refers to the amount of available data collected during the report period. The percentage of data captured is calculated using the following equation: Data capture = (Reported air quality data / Total data) x 100% Where: Reported air quality data = Number of instrument readings which have been validated through a quality assured process and excludes all data errors, zero data collection due to calibration, failures and planned and unplanned maintenance. Total data = Total number of instrument readings since the start of the term assuming no maintenance, errors, loss of data or calibration. Tables below display data capture statistics for August Bold values in the table indicate data capture below 95%. Details of all invalid or missing data affecting data affecting data capture are included in the Valid Data Exception Tables, see section 6.0 and attached Excel file.

63 Appendix 2 - Explanation of Exception Table Automatic filter tape advance refers to the movement of the filter paper by the analyser to an unused spot. Automatic background check refers to when analyser samples zero air and measures the level of the concentration voltage. This voltage is taken as the zero signal level and this value is subtracted from any subsequent readings as an active zero compensation. This is the analyser s fine zero measurement. Automatic span/zero check. The E-Sampler is programmed to perform a zero calibration check whereby air is passed through filter element, removing particulates, before entering the sensor in the analyser. Data is invalidated when these checks occur. Beta count failure refers to a fault in the functioning of the EBAM. A one minute beta count was less than the maximum acceptable counts during operation. Calibration check outside tolerance refers to when the calibration values are outside the tolerance limits set for the precision check. Calibration correction factor applied to data refers to an offset or multiplier applied to the data. This operation may be performed for a number of reasons including: (a) when a clear trend / drift outside the tolerance limit can be demonstrated by repeated operation precision checks, (b) when a correction is required on previously logged data due to a calibration check being outside the allowable tolerance Commissioning refers to the initial setup and calibration of the instrument when it is first installed. For some instruments there may be a stabilisation period before normal operation commences. Data transmission error refers to a period of time when the instrument could not transmit data. This may be due to interference, or a problem with the phone line or modem. Equipment malfunction/instrument fault refers to a period of time when the instrument was not in the normal operating mode and did not measure a representative value of the existing conditions. Gap in data/data not available refers to a period of time when either data has been lost or could not be collected. Instrument Alarm refers to an alarm produced by the instrument. A range of alarms can be produced depending on how operation of the instrument is being affected. Page 63 of 65

64 Instrument out of service refers to a lack of data due to an instrument being shut down for repair, maintenance, or factory calibration. Linear offset or multiplier refers to when an offset or multiplier has been applied between two points where the values of the offset or multiplier are different and the correction is interpolated between the two points. Logger error refers to when an error occurs and instrument readings are not correctly recorded by the logger. Maintenance refers to a period of time when the logger/instrument was switched off due to maintenance. Overnight span/zero out of tolerance refers to when the span/zero reading measured by the analyser during an automatic precision check falls outside of the expected concentration limits. Overnight zero out of tolerance refers to when the automatic zero reading measured by the analyser falls outside the expected limits. Power Interruption refers to no power to the station therefore no data was collected at this time. Remote Calibration refers to when a technician remotely connects to the station and manually performs a span check. Static offset or multiplier refers to when a single offset or multiplier has been applied to the data between two points either to increase or decrease the measured value. Tape break refers to the breaking of the EBAM/BAM sample tape during operation. Warm up after power interruption refers to the start up period of an instrument after power has been restored.
