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.

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.
