OF NRC BASELINE INSPECTION AND REQUEST FOR INFORMATION;
INSPECTION REPORT 05000315/2019004; 05000316/2019004
Dear Mr. Gebbie:
On October 7, 2019, the U. S. Nuclear Regulatory Commission (NRC) will begin the Baseline
Inservice Inspection (Procedure 71111.08). This onsite inspection is scheduled to be performed
October 7, 2019, thru October 24, 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 to ensure that the inspector is adequately prepared. The second group identifies
the information the inspector will need upon arrival at the site. It is important that all of these
documents are up-to-date, and complete, in order to minimize the number of additional
documents requested during the preparation and/or the on-site 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 Mr. M. Ellet of your organization. If there are
any questions about this inspection or the material requested, please contact the lead inspector
Mr. M. Holmberg at 630-829-9748 or via e-mail at msh@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.
