Re: Revised HCl and THC sections
	
		
		Keith/Amy,
		
		
		A few edits attached (to Keith's redline version) which edits will show up 
in bold.  Most correct typos or fix fact errors (like cross-references).  
However, I made some substantive edits to the discussion of the 20 
ppmv/98% reduction new source THC std.  The edits are to better tie that 
limit to performance of the source with an RTO (which is the legal test), 
rather than to the performance of RTOs generally.

Revised HCl and THC sections
	

	

Dear Amy:

I am sending the sections on the rationale for THC and HCl and the THC and 
HCl comments.  We have responded to your comments.

Note that there are one or two comment responses where the comment itself 
is moot, but because the issue may apply elsewhere we left the response in.


I have also included a redline version that compares what you previously 
saw for these section with the current version.
