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B&P on January 17, 1957, and was superseded by License STB-0362 on 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).

    Dated at Rockville, Maryland this 28th day of July, 2011.
