3 Executive Summary (Page 1 of 8) MONITORING OBJECTIVES, 27th November 2013 Overall Aim of the Monitoring Campaign Catalyst Environmental Ltd were commissioned by to carry out stack emissions testing on the A1 Gas Engine at. The aim of the monitoring campaign was to perform testing, as requested by the customer, for a number of prescribed pollutants. There are no emission limits set for any of the pollutants at this time. Special Requirements There were no special requirements. Target s Total Particulate Matter, Hydrogen Fluoride, Cadmium & Thallium, Heavy Metals, Mercury, Zinc, Dioxins & Furans, PAHs, Sulphur Dioxide, Hydrogen Chloride, Total VOCs (as Carbon), Oxides of Nitrogen (as NO₂), Carbon Monoxide Page 3 of 98
