Stack Emissions Monitoring Test House

ESG - East Kilbride Laboratory2-4 Langlands PlaceKelvin South Business ParkEast KilbrideG75 0YFUKAS and MCERTS Accreditation Number: 1015

Opinions and interpretations expressed herein are outside the scope of UKAS accreditation.MCERTS accredited results will only be claimed where both the sampling and analytical stages are UKAS accredited.This test report shall not be reproduced, except in full, without written approval of ESG.

MONITORING OBJECTIVES

ESG were commissioned by Medite Europe Ltd. to carry out stack emissions monitoring to determine the release of prescribed pollutants from thefollowing Plant under normal operating conditions.

Medite Europe Ltd. operates an extraction fan (press line) process at Clonmel which is subject to IPPC Licence P0027-02, under the EPA Act 1992.

EXECUTIVE SUMMARY

The results of these tests shall be used to demonstrate compliance with a set of emission limit values for prescribed pollutants as specified in thePlant's IPPC Licence, P0027-02.

The selection of standard reference / alternative methods employed by ESG is determined, wherever possible by the hierarchy of method selectionoutlined in Environment Agency Technical Guidance Note (Monitoring) AG2. i.e. CEN, ISO, BS, US EPA etc.

SRM - EN ISO 16911-1

BS EN 14790 has been validated over a range of 4 - 40%. It is however the prefered method of the Environment Agency for concentrations below 4%

PITOT LEAK CHECK

To complete a compliant pitot leak check a pressure of over 80 mmH₂O (or 800 Pa) is applied and the pressure drop monitored over 5 mins. A drop of less than 5% must be observed.
