Dear Sir:
p The purpose of this letter is to request an amendment to authorize additional use of special nuclear material.
The letter of March 3, 1977, described in detail, experimental work to be performed in Building 15, Denver Federal Center.
It now has been determined that the following four isotopes are necessary to be used as both counting standards and chemical tracers in radiochemical analysis:

Any Now this same project has also extended plans for sampling and transport of ground and trench waters from radioactive waste disposal sites.
Present plans call for initial sampling to be at Maxey Flats, Kentucky, but future work may also be done at one or more of the following waste disposal sites: West Valley, New York; Oak Ridge, Tennessee; Barnwell, South Carolina; Sheffield, Illinois; Nuclear Test Site, Nevada.
Survey employees will do the sampling.
Such parameters as pH, dissolved oxygen, temperature, E, and alkalinity will be measured on-site at the time of sampling.
Inadditkon, there will be some on-site, processing of the samples to include, but not necessarily limited to, sequential filtration through membrane filters, and acidification of some samples.
.j All of these operations will be done either "in the open" or in a Survey-owned f

Mr. J. Brown Gentlemen:
Pursuant to our application dated March 3, 1977, and the telephone discussion with Mr. J. Brown, it is respectfully requested that Condition D of this license be amended to reflect calculations for possession limits as follows:
D 15 milligrams special nuclear material in any form Sincerely,

mobile laboratory with careful monitoring with a portable alpha counter.
Total volume of samples collected could be as much as 200 liters. These samples will be returned to the Federal Center either by air freight or in the mobile laboratory; in either case applicable DOT shipping regu-lations will be followed.
/ The second project involves the increased use of isotopes Uranium-236 9 and Uranium-232 in the determination of accurate concentrations of Uranium by alpha spectrometry in Builing 15.
Current program evaluations indicate that 0.1 microcuries (0.005 ugms) Uranium-232 and 0.13 microcuries (2 milligrams) of Uranium-236 will fulfill project needs.
The third project requirement relates to the Survey letter of August 25, v
1976, describing program requirements in Building 21.
In order for this project to attain long range program requirements, it will be necessary to increase the possession limits to 5 milligrams of Uranium-233 and 5 milligrams of Uranium-236.
/ The fourth project requirement relates to a new tracer program in Building 15 involving 6 microcureis (100 micrograms) of Plutonium-239 and 1 millicurie (0.3 micrograms) of Americium-241.
All of the essential elements of these programs have been reviewed, discussed, and approved by the Survey Radiological Advisory Committee.
Accordingly, it is respectively requested that this license be amended to reflect these program requirements.
Sincerely,
(.
