Dear Mr. Rogers:

The Division of Waste Management and Radiation Control (Division) hereby provides follow up Requests

With this round of follow up RFIs, the Division recommends that appropriate staff from the Licensee, the
Division, and consultants meet to discuss each matter for clarity.

Please contact Larry Kellum at 385-622-1876 to schedule a meeting.

Sincerely,
