Hi,  
Thank you for your comments on the proposed rule.  I have a few  
questions:  
 
1) Do your member agencies have any stack test data from their engines  
that they would be willing to share with EPA?  In order to change the  
emission limit from what was proposed, we really need additional  
emissions data that supports the comments that the limit is not  
achievable.  
2) Are the engines that are operated by your members located at a major  
source of HAP emissions or an area source of HAP emissions?  A major  
source is a plant site that emits >10 tons/year of a single HAP or >25  
tons/year of combined HAPs.  Anything that is not a major source is an  
area source.  
3) We are exploring the possibility of requiring work practice standards  
rather than an emission limitation for these engines.  Can you provide  
any information on work/operational practices that are used for these  
engines in order to minimize emissions?

Dear Melanie -  
 
Please find attached a letter on behalf of the Air Issues and  
Regulations Committee of the Bay Area Clean Water Agencies regarding the  
proposed national emission standards for hazardous air pollutants for  
stationary reciprocating internal combustion engines. If you have any  
questions on the content of the letter, please feel free to contact me.
