Hi Cortney,
Attached is the information on the population breakdown for existing SI RICE 
and the cost of controls that you asked about during our briefing yesterday.  
Note that our information from engine manufacturers and landfill gas engine 
operators is that there are no landfill gas engines smaller than 500 HP so our 
estimates reflect that.  I'm also attaching a memo that breaks down the HAP 
emissions into the different pollutants, see the sheet for "Natural Gas" on 
the next to last page of the pdf file.  Please let me know if you need 
anything further.  Have a nice weekend.
(See attached file: Existing SI RICE population and cost info for OMB 7-2-
10.xls)(See attached file: EPA-HQ-OAR-2005-0030-0009 HAP EF for small 
engines.pdf)
