-,70 oft REG&,tV-UNITED STATES NUCLEAR REGULATORY COMMISSION o
WASHINGTON, D.C. 20555-0001 November 4, 1994 Dr. John C. Stauter Kerr-McGee Corporation Kerr-McGee Center Oklahoma City, OK 73125
Dear Dr. Stauter:
On September 4, 1987, Kerr-McGee Corporation submitted a request to amend License SNM-928 to allow disposal of soil contaminated with low concentrations of enriched uranium (EU) at Kerr-McGee's Cimarron, Oklahoma, site.
The request was made purz';ant to 10 CFR 20.2002 (formerly 10 CFR 20.302).
The soil to be disposed of was contaminated during the licensed opel.tions conducted at the Cimarron facility and is located on the Cimarron site.
The proposed disposal method is onsite burial.
Based on the Nuclear Regulatory Commission staff's review of the Kerr-McGee submittals related to the onsite disposal, the staff's analyses presented in the Safety Evaluation Report (SER) and the Environmental Assessment (EA),
and subject to new conditions in the license, the staff approves the amendment request (Amendment No.
- 10) to license SNM-928 (Enclosure 1).
Note that this approval relates only to disposal at the location described in Kerr-McGee's October 9, 1989, submittal.
Any other proposal to dispose of contaminated material on the Cimarron site will be evaluated on its own merit.
The staff prepared an SER for the proposed onsite disposal (Enclosure 2).
The purpose of the SER was to estimate the potential radiological impact on worker health and safety from the movement of contaminated soil to the disposal cell, and the placement and compaction of the soil in the disposal cell.
The SER concluded that a conservative estimate of worker dose is 408 mrem, predominantly from the inhalation of contaminated dust.
This dose is less than 10 percent of the occupational dose limit in 10 CFR Part 20.
However, in a letter dated November 3, 1994, Kerr-McGee committed to maintain a program to keep worker doses as low as reasonably achievable (ALARA).
Kerr-McGee's ALARA goal is to limit worker doses to approximately 250 mrem for the project.
Kerr-McGee projects that the actual doses for the project will be less than about 125 mrem.
The staff also prepared an EA for the proposed onsite disposal (Enclosure 3).
Based on the results of the EA, the staff concluded that the impact on the public and the environment would be minimal, and made a Finding of No Significant Impact (FONSI).
The FONSI, and an opportunity for a hearing on the amendment request, was published in the Federal Register on March 22,
- 1994, (59 FR 13513).

0 In the EA, the staff recommended several license conditions.
In addition, the Commission, in a staff requirements memorandum dated October 30, 1992, made a number of recommendations related to the onsite disposal at the Cimarron site.
The staff and Commission recommendations have been incorporated into a new license condition (Ccndition No.
23).
Amendment No.
10 to License SNM-928 also modifies five existing license conditions.
Condition 10 was updated to include the Kerr-McGee submittals related to the onsite disposal request.
Conditions 11 and 12 were modified to reflect changes in the new 10 CFR Part 20.
Condition 15 was revised to include the current reference for surface contaminationlimits for the release of equipment and materials from controlled areas.
Condition 18 was modified to clarify the existing condition that any contaminated solid waste generated during decommissioning, other than that designated for onsite disposal, shall be disposed of at a licensed low-level waste facility.Finally, Condition 20 was modified to reflect a commitment made by Kerr-McGee in a letter dated February 25, 1993, to submit a decommissioning plan for the remaining contaminated soil and structures on the Cimarron site.
Condition 20 sets a date of May 1, 1995, for Kerr-McGee to submit the decommissioning plan to NRC.
Please be advised that Kerr-McGee must conduct activities at the Cimarron site involving radioactive material in accordance with the conditions in License SNM-928, representations made in the license and amendment applications, as supplemented, and NRC regulations.
If you have any questions, please contact David N. Fauver of my staff on 301-415-6625.
Sincerely John Austin, Chief Low-Level Waste and Decommissioning Projects Branch Division of Waste Management Office of Nuclear Material Safety and Safeguards Docket No. 70-0925 License No.
