Reference: Silty Sand (Overburden) Radon Barrier Cover Material- Source Materials License SUA-551 - LicenseCondition 49.B.

Dear Mr. Holonich:

As discussed with your staff during our meeting on February 22,1996, a soil investigation program to further evaluate silty sandsources has been completed. The test holes from which materialis most suitable for use are plotted on the enclosed map titled" Silty Sand Borrow". Although the approved reclamation planstates that the silty sand cover material will be obtained fromexcavation of drainage channels and the area south and west ofthe southwest drainage channel (Reference the June 30, 1988submittal, page C-4), License Condition 49.B. refers only to thesouthwest channel area.

We request that License . Condition 49.B. be revised to allowexcavation of the silty sand (overburden) material from the areasouth and west of the southwest drainage channel, as well as fromthe channel itself. It is requested that this area include the16.3 . acre expansion of the NRC surety (restricted) areapreviously submitted for approval on April 26, 1996.

Also enclosed are-moisture-density analyses for the recent soilsinvestigation program, and two radon attenuation analyses. Themap shows the Proctor maximum dry densities at the holes in theareas considered most likely to be utilized. These densitieswere used to establish an average value for the parameter. Thisvalue is 121.3 pounds / cubic foot, on the basis of reportedmaterial thickness weighting. The average value withoutweighting is 121.1 pounds / cubic foot. Ninety five percent of

these maximum dry densities are 115.2 pounds / cubic foot and 115.0-pounds / cubic foot.

| Test holes for which no Proctor values were determined are: B-4,L B-6, B-9, B-11, B-13, B-16, B-17, and B-38. . Test holes not! considered likely to be used because of little available

material, too high fines content, or location at the extremitiesof the borrow area are: B-1, B-2, B-3, B-4, B-5, B-9, and B-11.i

!

It is Petrotomics intent to proceed with the construction of the!

silty sand and topsoil layers of tailings radon barrier coverthis year. Specifications for the silty sand cover require 95%of the Standard Proctor maximum dry density. Test frequencieswill be as per reclamation plan requirements: 1 Proctor per20,000 cubic - yards placed; 1 Gradation Atterberg Limits per-

5,000 cubic yards placed; and 1 field density per 1,000 cubicyards placed. In addition, because minor variation in specific

| gravity values has been noted, a specific gravity test will be! performed for each 40,000 cubic yards placed (with every otherj. Proctor test).

Two radon attenuation analyses are enclosed, labeled A. and B.Both analyses utilize the actual average density of the claycover, the anticipated density of the silty sand cover at 95%maximum dry density based on the recent soils investigationprogram, and the anticipated topsoil density originally used.

2Analysis A. shows that the radon exit flux is 16.2 pCi/m /sec,substantially less than the Criterion 6 standard of 20 in 10 CFR40 Appendix A. Analysis B. shows that with estimated backgroundlevels of Ra226 inc uded for the cover materials, the radon exitflux is 17.2 pCi/m /sec. The background Ra226 levels for theclay and silty sand are average values from recent tests. Theestimated value for the topsoil is the nominal surface soilsaverage in the area based on previous testing (e.g. referencePetrotomics letter dated October 14, 1985, which reports eighttests of surface soils background radium content resulting in

| values from 1.5 to 4.85 pCi/ga, with an average of 3.02).

It should be noted that the cover layer thicknesses used in the| radon attenuation analyses are the reclamation plan design

thicknesses. Consideration of additional thickness of covermaterials as discussed in our letter dated April 10, 1996,resulting from tailings shaping and settlement, would result inreduced exit flux.

|! Your expeditious approval of this request to amend License

,

| Condition 49.B. is needed in order to commence placement of the !

| final layers of radon barrier cover material. ji i
