REPORT 05000266/2019001
Dear Mr. Craven:
The U.S. Nuclear Regulatory Commission (NRC) will soon begin the Baseline Inservice
Inspection Procedure 71111.08. This onsite inspection is scheduled to be performed
March 25, 2019, through April 12, 2019.
Experience has shown that this inspection is resource intensive both for the NRC inspector and
your staff. In order to minimize the impact to your onsite resources, and to ensure a productive
inspection for both sides, we have enclosed a request for documents needed for this inspection.
These documents have been divided into two groups.
The first group identifies information necessary for inspection preparation. The second group
identifies information the inspector will need upon arrival at the site. It is important that all of
these documents are up-to-date and complete to minimize requests during the preparation
and/or the onsite portions of the inspection.
We have discussed the schedule for inspection activities with your staff and understand that our
regulatory contact for this inspection will be Ms. Kim Locke, of your organization. If there are
any questions about this inspection or the material requested, please contact the lead inspector
Mr. Matthew Domke at 630-829-9562, or via e-mail at MJD4@nrc.gov.
This letter does not contain new or amended information collection requirements subject
to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information
collection requirements were approved by the Office of Management and Budget, Control
Number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to
respond to, a request for information or an information collection requirement unless the
requesting document displays a currently valid Office of Management and Budget Control
Number.
