Hi Tad, 1 I hope our meeting yesterday was helpful. We will continue to work with you and your staff.

As I mentioned yesterday during the call we are currently in a rulemaking process for designations and need to be putting any written or oral communications in the docket. I was not able to catch all the names from everyone participating on your side, specifically the AE COM people. Could you please ask someone from your staffto send me the names ofthe people that were on the call yesterday? 1

### Thanks, Cristina

This is an extremely important issue for Maryland and is one ofthe few air quality issues that our Governors Office is directly involved in. This is why I'm pushing so hard. I apologize ifl've beentoo pushy, butthere is a lot ofpressure onMDE to get this right. As you know, my boss has asked us to set up a series ofcalls with Shawn Garvin to make sure all ofour efforts are successful. We are trying to use extremely sophisticated modeling to support our Governors recommendation of attainment. 2We need help from EPA to move this quickly and don't have the time to let weeks pass while the Region works to get approvals from the HQ folks. I've cc'd Chet and Tyler Fox on this note-- In the pastMD has benefited from significant help from Chet and his folks - and we appreciate that - so I wanted to keep them inthe loop. As we discussed last week, Ifwe need George Bonour weekly calls, I'm sure OAQPS would try and make that happen. Again, thanks for all ofyourhelp. Look forward to our call laterthis week onthe schedule and how the EPA guidance works for issues like new MATS controls and actual versus allowable emissions for an area with multiple sources contributing and ourcall next Monday orTuesday to hopefully get an agreement on the protocol. .
