### Particulate Summary 

# :3 Aaron Worstell to: Parker, James M 11/21/2011 10:04 AM
Hi JimThankyou for the PM stacktest data for Corette and Colstrip. The results shown for Colstrip 3 appearto be a little different than that in the ICR test report from September3, 2010 (attached). For example, forfilterable PM, the test report shows a rate of 0.0251 Ib/MMBtu (3 run avg.) while the spreadsheet you sent shows 0.0226 Ib/MMbtu (3 run avg.). There are other differences too. Do you happen to know whythese values differ?
