20545 Dear Mr.
Nussbaumer:
Regulatory File Cy.
Subject:
Amendment of License SNM-928, Docket 70-925, Burial of Trash Slightly Contaminated with Low Enriched Uranium With this letter the Kerr-McGee Corporation hereby files ap-plication #21 to the subject license for authorization to
- bury, on site, solid waste matter containing uranium with no greater than 5% uranium 235 enrichment, wifh the follow-ing stipulations (a.
thru d.):
- a.
A "burial" shall not contain more than 10,000 vPCi of combined uranium 234 and uranium 235.
- b.
Successive burials are separated by distances of at least six feet and not more than twelve burials are made in any year.
- t.
Burial is at a minimum of four feet.
- d.
The waste matter will typically consist of paper and cloth wipes, paper cartons, wood, plastic and metal scraps, brick, glass, leath-er, rubber, and assorted solid trash-type ma-terials.

Nussbaumer December 30, 1970 Page Two The methods used to assess the quantity of Uranium 234 and Uranium 235 in the trash-type solid waste follows:
- 1. A visual examination determines that the waste is typical type trash.
- 2.
The trash is packaged in 8 x 4 x 16-1/2" poly bags.
The bags are tagged showing the % U-235 enrichment of the possible uranium contamination.
- 3.
Four bags of trash are gamma scanned simultaneously in a scanning device which-detects one gram of Uranium 235 at twice (2x) background.
- 4.
Using the scanning device, only that-trash which counts very close to or at "background" is considered for burial.
- 5.
A second survey-of each individual bag considered for burial is made.
This is done using a portable gamma survey meter which is sensitive to all gamma.
The outer surface of the bag is surveyed thoroughly.
- 6.
Only that trash which counts less than twice background using the portable survey meter will be permitted to be buried.
Backgr6und must not exceed 0.10 mr/hr.
- 7.
Large pieces of "hardware" type junk are surveyed by a combination of visual examination for con-tamination, alpha counting of smears, and surface alpha readings.
The validity of the assay methods (1-6 above) has been verified by chemical analysis of many cubic feet of typical trash.
Your earliest review and approval of this amendment request will be appreciated.
It will better enable us to maintain a good house-keeping program, as well as minimize the fire hazard associated with an accumulation of combustible trash-type materials.
