<p class=MsoNormal>Hi Frank,</p>

<p class=MsoNormal> </p>

<p class=MsoNormal>Sorry for the delayed response. To answer your question (as
I understand it), The compliance date is 1/6/2014 for existing sources and they
will have up to 180 days from that compliance date to conduct their performance
test. Hope this answers your question, please let me know if you have any
further questions. I will be out of the office until 8/13, but will respond
asap as soon as I return.</p>
