Some info on Penetrations Donnie, Attached is a table that has elevation and azimuth information on the larger penetrations. Please pass on to Jason and let's set up a call for sometime later this week if possible. Ahmed is out at TMI for a plant walk down tomorrow, but we can perhaps discuss schedule for obtaining other information with Don W.

Thanks.

- John.
