3 SECTION 1B Executive Summary (Page 1 of 2), 18th 25th November 2016 Overall Aim of the Monitoring Campaign Exova Catalyst were commissioned by to carry out stack emissions testing on the Stack at. The aim of the monitoring campaign was to perform a QAL2 Calibration Exercise on the Continuous Emissions Monitor (CEM), which is installed on the Plant, following the requirements of EN Special Requirements There were no special requirements.

4 SECTION 1C Executive Summary (Page 2 of 2), 18th 25th November 2016 CONCLUSIONS, DISCUSSIONS & ACTIONS FROM THE SAMPLING EXERCISE Nitrogen Monoxide, Sulphur Dioxide, Carbon Monoxide and Oxygen A valid calibration function has been derived from the parallel tests which passes the variability test. This calibration function should be used and entered into the Data Acquisition Handling Software (DAHS). Linearity Checks The CEM was found to give a linear response to the test gases supplied to the analyser, passing the EN test of residuals requirement. Total Particulate Matter As the Total Particulate Matter emissions are of a low order (less than the 95% Confidence Interval [CI] of the Daily ELV, which is 30%) TGN M20 suggests calibrating the CEM using a calibration factor calculated by dividing the average of the SRM data pairs by the average of the CEM data pairs. This is as opposed to using linear regression. A valid calibration function has been derived in this manner. As the emissions are of a low order it is acceptable to leave the calibration function in the Data Acquisition Handling Software (DAHS) as (i.e. y = x). The CEM is effectively being used as a qualitative indicator of rising emissions rather than a quantitative monitor. The Environment Agency should be informed if this approach has been taken. Volume Flow Rate A valid calibration function has been derived from the parallel tests which passes the variability test. This calibration function should be used and entered into the Data Acquisition Handling Software (DAHS). In order to take in to account the wall effects described in EN the default WAF correction for brick and mortar stacks (0.9900) has been applied to the SRM Values. 4 of 53

6 Section 2: Information about the Regulated Installation OPERATIONAL INFORMATION AND SITE MONITORING PROVISIONS, 18th 25th November 2016 Process Type and Variations in Emissions Parameter Continuous or batch process Were there any variations in emissions during the EN test (e.g. Load changes) Will these variations affect the representative nature of the collected data? Are there any factors that may affect the collected data (e.g. autocalibrations, plant start up and shut down) Reviewing historical Plant data, were low emissions expected for any determinands? Was the CEM reading zero for any determinands, if so, was this investigated to ensure it was working? What product was being processed during the tests? Value Continuous No periods of calibration removed from paired data. Carbon Monoxide All linearity checks proved CEMs was performing correctly. Type of Fuel Parameter Fuel type used during the EN test (include proportions for coincineration) Are multiple calibration functions required if the emissions vary due to different fuel types being used?
