Also I had one more question, do any of these engines have emission controls 
like SCR, oxidation catalyst, etc?

Hi,
Thanks so much for sending the data, I really appreciate it.  A couple of 
questions - what is the difference between the two spreadsheets?  For example, 
are the Red Dog Mine engines in the "Rural Alaska NSPS engine"

file the same engines as the Red Dog Mine engines in the "IC_Engine Source 
Tests" file?  If so, why are the emissions so different?  In the "Rural Alaska 
NSPS engine" sheet, why are the PM test results the same for multiple engines 
at the same facility?  Were they tested and all the engines had the same 
emissions?  Finally, can you tell me what test method was used for the PM 
tests?
