NUCLEAR REGULATORY COMMISSION
[NRC-2011-0177; Docket No. 40-00235, License No. STB-0362 (Terminated)]
AAR Manufacturing, Inc.; Completion of Radiological Survey
Activities at CSX Transportation Property Near Inkster Road in Livonia,
MI
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice of acceptability.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is noticing the
acceptability for unrestricted use of the CSXT property near Inkster
Road in Livonia, Michigan.
ADDRESSES: You can access publicly available documents related to this
notice using the following methods:
NRC's Public Document Room (PDR): The public may examine
and have copied for a fee publicly available documents at the NRC's
PDR, Room O1 F21, One White Flint North, 11555 Rockville Pike,
Rockville, Maryland 20852.
NRC's Agencywide Documents Access and Management System
(ADAMS):
Publicly available documents created or received at the NRC are
available electronically at the NRC Library at http://www.nrc.gov/reading-rm/adams.html. From this page, the public can gain entry into
ADAMS, which provides text and image files of the NRC's public
documents. If you do not have access to ADAMS or if there are problems
in accessing the documents located in ADAMS, contact the NRC's PDR
reference staff at 1-800-397-4209, 301-415-4737, or by e-mail to

Background: The CSXT property located near Inkster Road is not
subject to a license issued by the NRC. It consists of operating rail
lines and associated right-of-way and is located to the west of Inkster
Road in Livonia, Michigan. The parcel is adjacent to, and runs parallel
to, the southern boundary of the AAR Manufacturing, Inc. (AAR) site.
The AAR site was formerly owned by Brooks and Perkins, Inc. (B&P), a
licensee of the NRC's predecessor agency, the U.S. Atomic Energy
Commission (AEC). AEC Source Material License No. D-547 was issued to
B&P on January 17, 1957, and was superseded by License STB-0362 on
August 10, 1961. AEC terminated License STB-0362 on May 17, 1971. In
1981, AAR purchased B&P and obtained the property. In March 1994, the
NRC informed AAR that radioactive thorium surface and subsurface
contamination had been detected at several locations on the site and
requested that AAR perform radiological surveys and remediation
activities (ADAMS Accession No. ML110670259). The AAR site was added to
the Site Decommissioning Management Plan list in August 1994.
In May 1997, NRC inspectors performed a limited radiation survey of
the CSXT right-of-way adjacent to the AAR site. NRC staff provided the
inspection report to CSXT in a June 12, 1997, letter; the report
identified three locations with elevated levels of thorium in the soil
(ADAMS Accession No. ML091000360). NRC staff considered the possibility
that some residual radioactive material may have spread from the AAR
site onto the CSXT property. In a September 8, 1997, letter, NRC
requested that CSXT provide an accurate characterization of the
property (ADAMS Accession No. ML101250613). CSXT submitted the report
to NRC on September 13, 2000 (ADAMS Accession No. ML090680748). The
CSXT conclusion in this report was that the dose modeling results
demonstrate that no remedial actions or restrictions on site usage are
required and that the total site dose does not exceed the 25 mrem/year
NRC criteria for unrestricted release. NRC staff reviewed the CSXT
report and concluded that the surveys and measurements were generally
not consistent with NRC guidance. After evaluating the existing data
for the CSXT property, the NRC staff decided to have the NRC
independent survey contractor perform confirmatory surveys of the CSXT
property.
Based on the survey and sampling results, as well as an all-
pathways analysis of the potential doses to the public from the
residual radioactivity at the site, it was determined that
contamination on the CSXT property would result in doses well below
NRC's criteria for unrestricted use. Therefore the NRC staff concludes
that no further action is needed by CSXT. NRC will not require
remediation activities at the site unless new information demonstrates
that the criteria in 10 CFR Part 20, Subpart E, ``Radiological Criteria
for License Termination,'' are not being met and residual radioactivity
at the site could result in a significant threat to public health and
safety. The NRC staff documented its review in a Safety Evaluation
Report (SER) (ADAMS Accession No. ML111370451).
