No license was ever issued.
3. Contamination, Demography and Size of Problem -
In an attempt to decontaminate the Latty Avenue property in Hazelwood, Missouri, Cotter Corporation mixed 8,700 tons'of leached barium sulphate residues with 39,DDO tons of dirt and disposed of this material at the Hestlake Landfill.' There are two rather large areas of contamination. No information is currently available relative to the concentrations of the radionuclides. NRC is performing a radiological survey to determine the.nature and extent of the contamination. The landfill is located in .'; an old limestone quarry in the heavily populated St. Louis suburb.
4. Remarks -
,#hen the radiological survey is complete,,late this year EY 91). the staff will.evaluate, what if any, remedial action is necessary.

1: - Name Location
McGean Dump I Newburg Heights, Ohio.
2. ,License, Status -
No NRC/AEC l icense was .involved.
3. Contamination; Demography and Size of Problem -
The contamination resulted from the decontamination of the property which was formerly owned by Chemetron, a source material l icensee; by the purchaser Hctean Chemical Company. The'contamjnation is depleted uranium oxide (U3OG) on building'rubble and the estimated volume is less thank 29 yards. The quantity of source material is unknown. The McGean dump is located in an industrial area inter m ixed with residences in a suburb of Cleveland.
4. Remarks -
It is anticipated that this problem will be resolved by the staff position paper .dn disposal of uranium residues either by burial ,at the dump or by removal to the themetronproperty and burial.

2. License Status -
No license was ever issued.
3. Contamination, Demography and,Size of Problem -
The contamination is tailings from thorium processing at ttaywood Chemical Company (now Stepan Chemical Co.). The tailings were moved there by the owner of the'iproperty prior to the Atomic Energy Act. The DDE is currently surveying the property to determine the extent of contamination. The State of Now Jersey is investingating whether or not they have funds available to decontaminate the property and also whether or not Stepan will accept the material for storage under their license if there is no"' other place to move the material.
The area,is residential but only two residence are involved.
4 . ,,Renarks -
No action is needed by NRC; however, we have offered to help the State by providing radiological coverage during removal of the material.

1. lz Location
Stepan Chemical Company Maywood, New Jersey
2. License Status -
The area.of concern was an authorized place of use under'stepan Chemical Company's Source Material License STC-130. The site was formerly owned by Naywood Chemical Company who produced thorium mantles for gas lights as well as 'other chemical products. NayWOOd Chemical produced lithium hydroxide under contract to the AEC but it is unknown whether or not they produced thorium products for the AEC.
:: 3. Contamination, Demography and Size of Problem-
The main contamination is located'in tWD specific areas where two former tailings dams were located. It is roughly estimated that if 4,000 yards." .. of material was removed from the site the entire site could meet our criteria for release for unrestricted use. The main contaminant is thorium and the bulk of the area averages less tham 5 pCi/gram. The highest concentration is in a small area, < l/2 acre Where tailings still exist With concentrations as hig,h as 1600 pCi/gram. The site is zoned industrial .but some private residences abut the southern boundary.
4: Remarks - '.
The property o&ersare talking to Stepan Chemical to convince them to accept the material and include it as part of their existing source material 1Scens.e. Stepan is currently authorized to store wastes in under- ground pits by Source Material License No. STC-1333.

Company was engaged in the extraction of rare-earths from monasite ores. The,source material was a byproduct of this .activity. Prior to 1fcensi.n in 1966, Michigan Chemical Company (KC) manufactured purified rare-eart s il. from concentrates for the AEC in AEC owned facilities which MCC purchased from the AEC in the early 1960's. ; ,:.
Contamination, Demography and Size of Problem -
Dne building and a small portion of the grounds are contaminated with thorium; however, Velsicol has been using.the site for the manufacture."' of hazardous organic chemicals such as PBB, DDT, Tris and HBB and the entire 50 acre site is contaminated with these compounds., EPA is currently working with Velsicol to require them to isolate_ the property
.t.o prevent migration of the organic offsite. It is the staff's opinion that the EPA requirements adequately protect.the .public from the thorium residues.
Since the.licensed activity was only a small portion of the overall chemical operations, the radioactive contamination is minor compared to the chemical contamination. Most of site is at background-levels although some hot-spots have:a. grass alpha'activfty as high as 13,000 pci;,/gram;
Remarks -
The next action is to reach an .agreement with EPA on the best method to include radioactivity in their enforcement action., This is currently under review by, ELD.

3. Con~tamination, Demography and Size of Problem - :'
Originally, four buildings and 11 'l/2 acres were involved but the buildings. and the 3~1/2 .acres surrounding them were decontaminated and released for unrestricted use.
At present, no buildings are involved but approximately 7 acres of land contains an estimated 3D.,ODO cubic yards of dirt that is contaminated with ore residues khich were generated from the processing of ores by Mallinc'krodt Chemical Co. for the Manhattan Project. Aboti 12,000 cubic yards df dirt was accumulated during the decontamination of the 3 l/2 acres and the buildings; this is now stored in a pile onsite. The estimated additional 18,000 yds3 will be generated during completion of
.the decontami_nation effort.
The facility is surrounded by.other industrial plants. The nearest residences are located approximately one mile away; however, it is located in heavily,populated St. Louis County.
The contamination was identified by IE Region III and a formal radiological survey was performed for IE by OR&.
” The main contaminants are natural uranium, radium 226, thorium 230, protitinium 231 and actinium 227. The average level of activity is 9300 pCi/gram of which the main constituent is Th-230 with an activity of 8860 pCi/gram. The highest Th-230 concentration measured in the original survey indicated concentrations.as high as 36,000 pCi/gram on the surface.
4. Remarks -
Cotter Corporation, the last licensee, has contracted to pay for the decon- tamination effort. The only problem has been finding a'suitable disposal site. It has been suggested that the dirt be moved to an old AEC storage site, where the residues originated, adjacent,to the St. Louis Airport; however, the AEC gave this property and the.associated responsibilities to the City of St. Louis and the City now refuses to accept the Latty Avenue material unless DDE agrees to retake possession of~the property.

2. License Status -
Formerly l icensed for possession.and use of zirconium ores cdntaining about 6: thorium oxide. (License STB-440. Docket No. 40-5001)
Amax Inc. has applied for a storage-only l icense to cover the remaining low-level radioactive soil located at the site. '
3. Contamination, Demography and Size of Problem - . .
The contamination consists'of thorium. The estimated volume of soil contaminated with thorium is 1.5 m illion cubic feet. The maximum level of contamination is about 1.6% thorium. There are no contaminated .;, structures.
Land use near the site is industrial to the north and agricultural to the south. ' The population in the area is low.
"!&ax, Inc; has proposed that the contaminated ,soil be stabilized on-site for st,orage under l icense. This could be done by the movement of 8.300 cubic yards of contaminated materialto the area which contains the bulk of the -thorium;contaminated soil.
Zirconium and/or magnesium in pyrophoric form has been buried at the location which contains the bulk of the contaminated soil. Movement of the soil in this area has,, in the past, resulted in fires and explosions.. The Amax, Inc. plan for stabilization would not require moving or exposing the pyrophoric material.
" 4. Remarks -
The Amax. Inc. plan for site stabilization:and storage of waste.is . under review. An Enviromnental Impact Assessment has been drafted by SRI for NRC and is being reviewed. Action to authorize sale storage under . l icense is expected this calendar year (CY 82)..

Following bre Identified current NRC licensees who plan or hdve initiated . decontamination and decozzaissioning actions on plutonium fuel facilities
-'in their possession. Each licensee continues to possess the necessary skills and resourcestoactomplish the:task which involves the decontamination of equipment and related structures to levels established by the NRC or the packaging of such materials along with wastes generited during the decontamina- tion process for ultimate disposal. However, a major problem faced by these licensees is the disposftion of the contaminated wastes. Sfnce early 19B0, no ccm%ercial disposal site is, authorized to receive and dispose bf trcnsuranium (TRU) 'wastes that exceed a concentration of 10 nCLl/orati. Because.of this situation, some lic&sees have ceased or have not'initiated decontamination zctivities. Others are proceeding by pcckaging the wastes as they are generated for.temporary storage onsite. Both the industry and the NRC have urged DOE
I to accept these TRU.wastes, with.apprqpriate changes. for 'Yetrievapre." storage.- - at DOi sites in the manner that DDE defense TRU wa= are bein<-stored 'fbrk eventual disposal in a Federal repository. DDE has responded by conducting a study to determine the volume of was~te involved, estimated the costs 'for storage and djspo>al, and provided. general packaging criter'la, but has indicated it does not believe'it possesses the authority to accept the waste. ti action has been taken to obtain such authority. Full-scale efforts by the Jicensees identified below vouid result in the generation of a few tens 'of 'thousands cubic fe!: of waste over the two to three years required to accomplish the decontamination of the facilities, but this volrnne wouid represent only a small fraction of the . TR'J waste~accumtiat~d from DDE defense-related activities. Subsequent to this . peak period, the volume of TRU waste generated in the commercial sector by exirt:ng licensees would be limited to a few hundred cubic feet per year from source manufacturers and R&D hot cell activities.
