SOCOTEC - 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 SOCOTEC LTD.

MONITORING OBJECTIVES

SOCOTEC LTD were commissioned by Medite Europe Ltd to carry out stack emissions monitoring to determine the release of prescribed pollutantsfrom the following Plant under normal operating conditions.

Medite Europe Ltd operates a wood fibre board manufacturing process at Clonmel which is subject to IE Licence P0027-04, 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 IE Licence, P0027-04.

EMISSIONS SUMMARY

ND = None Detected,Results at or below the limit of detection are highlighted by bold italic text.The above volumetric flow rate is calculated using data from the preliminary survey. Mass emissions for non isokinetic tests are calculated using these values. For all isokinetic testing the mass emission is calculated using test specific flow data and not the above values.
