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 UK LTD.
MONITORING OBJECTIVES
SOCOTEC UK LTD were commissioned by Masonite Ireland to carry out stack emissions monitoring to determine the release of prescribed pollutantsfrom the following Plant under normal operating conditions.
Masonite Ireland operates a first stage fibre drier process at Carrick-on-Shannon which is subject to IPPC Licence PO021-02, 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, PO021-02.
Stack Gas Temperature oC 56.0 - -Stack Gas Velocity m/s 10.24 0.24 -Gas Volumetric Flow Rate (Actual) m³/hr 154491 7886 -Gas Volumetric Flow Rate (STP, Wet) m³/hr 129096 6589 -Gas Volumetric Flow Rate (STP, Dry) m³/hr 108472 5537 -Gas Volumetric Flow Rate at Reference Conditions m³/hr 215185 10984 -

EMISSIONS SUMMARY
P
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.

Pre Traverse Leak Rate
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.
