05000266/2017004; 05000301/2017004
Dear Mr. Coffey:
On October 10, 2017, 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 10, 2017, through October 27, 2017.
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 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 Mr. T. Schneider of your organization. If there are
any questions about this inspection or the material requested, please contact the lead inspector
Mr. J. Neurauter at 630-829-9828 or via e-mail at James.Neurauter@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.
