Dear Mr. Johnsen:
In the manufacturing process licensed for Hematite, Missouri, we geneaste sub-stantial quantities of assacmium fluoride solutians from the precipitatien of ammaanium diuranate, Our current prosedure for h=414ag this material is to tawat it with line to precipitate the flueride values, bring the alarry to the boiling point to release the ammonia, filter out the calcium flucride residnes and send the essentially pure water to'the stream. Se caloitus fluoride resi-does are being stored in d 9sas under cover at the plaat site.
A proosse is in oposution in ear sain' plant in St. Louis, Missouri which can utilise all of the --a=4-f1moeide solution that is generated at the Besatite, j
Missouri p3 ant. These filtantes have been repeatedly analysed as a routine proossa senteel measure and have been found to centain an assesgo =mw4=== at 50 pga solels imunian, with the avenuse = lass in the amass of 5 to 20 ppa of solub3e graninus, this uranima is not recovered by the liso treatment.
We are n'a==i=e to eesse the line treatsmat of the samenium fluoride residass and transport these solutione by ocupaneconed tank wagon to our smin works at St. Louis for utilisatian of this valmble by-prodnet. We are proposing to puedess a $000 gallan taak Because of weight limitaties an axla lead-lag a Missowi hidummys, we land this tank to a meriums of about )$0 gallene.
In the ooerse of our operaties we have made routine abooks en the assaism oco-testi et emets filtestes aus to fine that even if the tank were ocup3sta3r tilled with car metaldens' that un usu3d Aall moder the.ensuptian far iden.1

It is not completely cloar to us whether our propocod action need be covered by a modification to our Special Nuclear P.atorials License. If you feel that it chou 3d be so covered, however, we request that SNM-33 be so amended.
