  |docket number for Thunder Creek test

Cortney,
During our call today you asked for the docket number for the Thunder Creek 
Compressor Station test.  It is EPA-HQ-OAR-2002-0059-0590.  Turns out I was 
mistaken and it wasn't one of the ones that we received post-proposal.  It is 
a report that we already had in the docket from the 2004 NESHAP, which we did 
incorporate into the record for this rule.
I don't know why it wasn't used when we calculated the MACT floor at proposal.  
I joined the project when work was already ongoing on the proposal, and as far 
back as my records go, it wasn't used in the analysis for the proposal.
