sure is well below the detection limit of available detection devices. How you demonstrate 99.9999% removal is another matter again.<o:p></o:p></p>

<p class="MsoNormal">52 Destruction efficiency<o:p></o:p></p>
<p class="MsoNormal">(1) Group 6 treatment plant (other than flares) must be operated in such a way that the destruction efficiency of the plant, in relation to an air impurity entering the plant, is:<o:p></o:p></p>
<p class="MsoNormal">(a) if the air impurity originates from material containing any principal toxic air pollutant-more than 99.9999%, or<o:p></o:p></p>
<p class="MsoNormal">(b) in any other case-more than 99.99%.<o:p></o:p></p>

<p class="MsoNormal">(3) A reference in this clause to the destruction efficiency of Group 6 treatment plant in relation to an air impurity (including landfill gas) is a reference to the destruction efficiency of the plant, in relation to the air impurity,
calculated by using the following equation:<o:p></o:p></p>
<p class="MsoNormal">DE = (1 - MWout / MWin ) x 100<o:p></o:p></p>

<p class="MsoNormal">"MWout" is the mass emission rate of the air impurity in exhaust emissions prior to its release to the atmosphere using a 1 hour rolling averaging period.
