I haven't been following the discussion, but as of now I have two interagency briefings scheduled on the SOx NAAQS:
10am for standards and rationale (if we finish a few minutes early, great!) 2pm to cover implementation

Let me know if I have misunderstood.
Also, Chet, do you have a conference line we can use for the afternoon call?

Thanks all,

heidi

I can live with that, but history is we always take longer on the standard than we predict and I just don;t want to have folks sitting around when they can be working other issues. We can try it and see...

Either way is fine with me, as I plan to attend both meetings. It seems to me that it would make sense to have everyone on the first call, and begin discussion of the monitoring, etc. issues once we complete the standard discussion, which I don't believe will take too long, and then have the second hour to discuss whatever we don't get to in the first meeting. I think because the standard discussion should be relatively short in this meeting, it makes sense to have the whole team on the phone and get through as much of the package as we can in the first meeting, and have the second to complete the discussion if need be. Then, in subsequent meetings, where we anticipate a fuller discussion of NAAQS issues, we can have separate meetings on monitoring and modeling, as need be. Does that make sense to you?From: Richard Waylan d / R TP / U SEPA / U S

I had assumed the first was on the standard and the second on the implementation, which covers the monitoring/modeling. Whatever works best, but when we try and do all together, we never get time for the implementation side, so that's why we proposed 2 separate meetings. Plus, we would not have to have all the implementation folks on the first call if we're focusing just on the standard. Hoping to maximize folks time as well.

I need some clarification of what we're doing on Thursday. Is the first meeting in the morning just to discuss the standard and nothing about monitoring, modeling and implementation? If so, we don't need a full hour for that meeting, as it will not take us long to explain the standard and the basis for the decision. We had thought we could use the first meeting to go over the specifics of the entire package, including an overview of the monitoring and implementation provisions, and the general role to be played by modeling, and then have a further discussion on SO2 modeling in the afternoon. Please let me know if this makes sense to the two of you or if you want to have just a NAAQS discussion in the morning, in which case we'll shorten the morning meeting. Thanks.

Heidi,
Looks like most of the monitoring/implementation folks can be available after 2pm Thursday 5/6. Do you have a preferred time between say 2pm and 6pm?

Chet

Chet, that sounds like a good idea. Thank you for suggesting it.
Let me know if there is a time Thu 5/6 that works for your folks -- that looks like a good day on our calendars.

Best regards,

Heidi,
Thanks for the call today. With regards to next weeks follow-up call, it might be beneficial to have a first call on the science and standard aspects and then a second call on any monitoring/implementation questions. As you can imagine, the monitoring and implementation parts are complex. If that approach works for you, let me know and we can coordinate with you on the second call while Lydia's folks handle the first call. We'll obviously have everyone on both calls, but since my folks are more critical on the second call, we'd like to make sure we schedule around their schedules as much as we can. Let me know if you think this approach works for you.Thanks, Chet
