2.3.1. Compliance with Standards Unless stated below, parameters are monitored at the Transurban QLD Network according to the methods detailed in Table 4.
2.3.2. 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, except for beta attenuation monitor dust parameters which are logged in 1 hour intervals.
2.4. Data Validation and Reporting
2.4.1. 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.
2.4.2. Reporting Data is reported separately in two Microsoft Excel format files named “Transurban QLD Legacy Way Monthly Data Report_February 2020.xls” and “Transurban QLD Legacy Way Monthly Met Data Report_February 2020.xls”.
The Transurban QLD Legacy Way Monthly Data Report_February 2020 Excel file consists of ten worksheets:
1. Cover 2. Contents
Page 16 of 72
Legacy Way Air Monitoring Network Report No: DAT15541 Transurban QLD
3. 5 Minute Data 4. 1 Hour Data 5. 1 Day Data 6. CO 8hr Rolling 7. Span 8. Zero 9. Precision 10. Valid Data Exception Report
The Transurban QLD Legacy Way Monthly Met Data Report_February 2020 Excel file consists of six worksheets: 1. Cover 2. Contents 3. 5 Minute Data 4. 1 Hour Data 5. 1 Day Data 6. 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 PM10 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.
Ecotech typically reports decimals places for concentration values according to relevant Australian Standards and the resolution of each instrument, refer to Table 8 for more details. Additional decimal places are included in this report as requested by the customer.

5.0 Results
5.1. Data Capture
Data capture refers to the amount of valid data collected during the report period excluding overnight calibrations, routine maintenance3, power interruptions and shadows on solar radiation sensor. It is based on 5 minute data, for all continuously monitored parameters. Except for BAM1020 dust parameters which are based on hourly values.
The percentage of valid data captured is calculated using the following equation:
Data capture = number of valid data points obtained Total number of data points for the period – Reasonable exclusions data points Where:
• Number of valid data points obtained = Number of samples (instrument readings) which have been validated through a quality assured process and excludes all data errors, zero data collection due to calibration, equipment failures, power interruptions, data transmission errors, planned and unplanned maintenance.
• Total number of data points for the period = Total number of samples (instrument readings) expected for the sampling period. Total data is calculated based on the same averaging period as “reported air quality data” and the duration of the corresponding report period. e.g. for 5 minute data collected over a month of 31 days, the total data would be equal to 12 (5 minute samples in an hour) x 24 (hours in a day) x 31 (days in a month) = 8928 samples.
• Reasonable exclusions data points = Number of samples which have been invalidated due to overnight calibrations, routine maintenances3 and shadows on solar radiation sensor.
Tables 15-20 below display data capture statistics for February 2020. 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 files.
3 Routine maintenance is estimated time for 1 monthly, 3 monthly, 6 monthly, 1 yearly and 2 yearly tasks performed by Ecotech. For zero and background tests, data is excluded from the whole period that the test was performed.

Appendix 2 - Explanation of Exception Table Automatic filter tape advance refers to the movement of the filter paper by the analyser to an un- used 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 71 of 72
Legacy Way Air Monitoring Network Report No: DAT15541 Transurban QLD
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.
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.
Shadow on sensor refers to the same period of time everyday when a shadow is cast over the solar radiation sensor causing unnatural low readings.
Stabilisation after power interruption refers to the start up period of an instrument after power has been restored.
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.
