Subject: 
SBAR Panel for Mobile Source Air Toxics –Control of 
Hazardous Air Pollutants from Mobile Sources 

Dear Mr. Cristofaro: 

I received your letter regarding the Small Business Advocacy Review Panel 
(Panel) for the proposed Clean Air Act rule entitled Mobile Source Air Toxics (MSAT) – 
Control of Hazardous Air Pollutants from Mobile Sources. The formal notification of the 
Panel was received by the Office of Advocacy on June 3, 2005. 

Advocacy concurs with the preliminary list of Small Entity Representatives 
(SERs) that EPA has proposed for Panel process. We understand that EPA would like to 
have a pre-Panel meeting with the SERs in the next few weeks and convene the Panel in 
September. This timeframe should be workable. We look forward to working with you 
through this process. 

Sincerely, 

 /s/ _____________________
