Dear Mr. Fauver:
Please find attached a license amendment request as required by Condition (D) of license SNM-1999 for the purpose of delineating boundaries of radioactive materials areas, restricted areas, and areas outside of restricted areas where licensed materials exist.
The date for submittal of this material was extended'to not later than June 8, 1993 in = telephone conversation between you and E.T.
Still of Kerr-McGee va June 1, 1993.

DOCKET NO.' 70-3073 CUSHI.NG, OKLAHOMA REFINING SITE KERR-MCGEE CORPORATION i
JUNE 2.1992 E
Condition 11.D. of License SNM-1999 directs Kerr-McGee Corporation (Kerr-McGee);
to submit, by license amendment request, "- the proposed boundaries of all radioactive materials.
areas designated in accordance with 10 CFR 20.203(e) (2), restricted areas as defined in 10 CFR 20.3, and areas outside of restricted areas, where licensed materials exist which must be secured ~
from unauthorized removal per 10 CFR 20.207." At the request of Kerr-McGee, NRC staff agreed to a one-week extension of the June 1,1993 submittal date. The proposed boundaries-l]
are described below and are shown on the accompanying map of the Cushing site.
i General Site Control Kerr-McGee limits access to the portion of the former refinery site currently owned and
?
to some portions of the site not currently owned by means of a fence with locked entry points.
This_ area to which access is limited is comparable to a " controlled area" as defined in 10 CFR
- 20.1003, i.e. " Controlled area means an area, outside of a restricted area but inside the site j
boundary, access to which can be limited by the licensee for any reason." The extent of the area controlled overall is outlined on the attached site map.

- 1 Restricted Areas - 10 CFR 20.3 Under 10 CFR 20.3, a " restricted area means any area access to which is controlled by the licensee for purposes of protection of individuals from exposure to radiation and radioactive materials." On the basis of radiation surveys and anticipated future activities required in the remediation, six areas within the site are designated as a restricted area. These areas, located on the attached map by block number, are: No. I the trash dump - blk #4, Nos. 2,3,4, tank dikes in blocks 29, 41,43, No. 5, Pit 4 in block 23, and No. 6, the processing buildings in block 101.
The perimeters of these areas have been, or will be, delineated by fencing, or other physical barriers and posted with the conventional radiatin symbol.
Radioactive Materials Areas - 10 CFR 20.203(3) (2) 10 CFR 20.203(e) (2) provides for conspicuously posting of areas in which retural uranium or thorium is used or stored in any amount exceeding a specified quantity. Outside of the areas designated as restricted areas, which are or will be conspicuously posted, available data do not indicate the quantity specified in 10 CFR 20.203(e) (2) has been, or is likely to be, exceeded in any defined area or room.
Amendment Request #1 6/2/93 PAGE 2
Nevertheless, Kerr-McGee has designated as radioactive materials areas those locations at which the characterization survey indicates an external gamma exposure rate greater than 15 microR per hour. These areas are identified on the attached map. The perimeter of these areas have been, or will be, marked using steel T-posts and plastic caution tape. A sign with the radiation caution symbol and the words " caution" and " Radioactive materials" will be placed in the center of small areas; similar signs will be posted at appropriate intervals along the perimeter of larger areas.
Additional areas may be designated as radioactive materials areas on the basis of scoping surveys being performed at drainage ways, at areas identified in the characterization survey with elevated exposure rates and at locations for which anecdotal information indicates licensed materials might be present. The surveys consist of area scans with a sodium iodide detector to identify areas with gamma exposure rates in excess of two times background. Gamma spectrum analysis of soil samples will determine the requirement for conspicuous posting.
Unrestricted Area Storace and Control-10 CFR 20,207 Some licensed material has been identified as contamination in soil in an unrestricted area that is not within the sit perimeter fence. This area is within the North tank farm that is owned and operated by a wholly-owned subsidiary of Kerr-McGee Corporation. Tank farm areas determined with a sodium iodide detector to contain activity exceeding two times background Amendment Request #1 6/2/93 PAGE 3

- have been delineated and flagged and are posted as a radioactive materials area, as identified on the attached map. The only work routinely performed in the area ~of contamination is grass -
mowing for fire prevention purposes. The mowing is' performed under a special work permit.
Some licensed material is stored in the form of soil samples in the radiological crew trailer and in the site of6ce building. The crew trailer, sample storage room and soil counting room are locked when no one is present. The trailer location and office building are shown on the attached map.
