50360132 (DN 50359698).pdf Hello Greg, Attached is a summary of the status of the notifications lis ted below. I also attached the notifications.

Some of them were changed from a DN to a DA so I attached both.

Please let me know if you have any questions.

Thanks Brandy Sizemore

Notifications and other general questions Good morning, I have listed the Notifications that are discussed in the inspection report and would like updated copies of the Notifications and any corrective actions taken, completed or planned.

50313350 50333175 50335453 50336850 50341482 50341635 50341717 50341749 50341752 50341848 50341874 50341877 50341879 2 50341911 50359698 As a ballpark figure - how many components are listed in the LR Database created in preparation for the application? I figure 10s of thousands but do not really know.

How many of your license renewal programs had no proposed or draft procedures developed?

Did you create a Master Tracking Notification or matrix for your programs? If so could I get a copy?

Do you have a notification tracking the long term plan?

Do you know the number of individual requests for information that you have received, including followup requests? I know that you have ~200 Requests for Information without counting followup questions?

Have a great day!!
