Re: Ucense SUA-1473Docket No. 40-8905

Dear Mr. Lusher,

Please find enclosed information associated with re-qualification of the erosionprotection rock Rio Algom will use for reclamation activities at the Ambrosia Lake facility.This information was requested by NRC in letters dated February 25,2002, and November27, 2002. Laboratory results along with an engineering overdesign of 4% indicates thatthe Tinaja Pit rock is of sufficient grade to assure protection for the 1000 year designrequirement specified in Criterion 6 of 10 CFR Part 40, Appendix A.

Please contact Terry Fletcher at(505) 287-8851, extension 200. if you have anyquestions.

Rio Algom Mining LLC - Ambrosia Lake MillErosion Protection Durability Test Results

In response to US Nuclear Regulatory Commission requests dated February25, 2002 and November 27, 2002, Rio Algom submits the following informationthat demonstrates the erosion protection obtained from the Tinaja Pit is ofsufficient grade and quality for use on some components of the site reclamationproject. Regulatory requirements establish a 1000 year design criteria for erosionprotection.

Rio Algom, along with other uranium mill sites in the area, previously acquired allerosion protection materials from a quarry that produced basalt rock.Subsequent closure of this basalt pit precluded its use and alternative rocksources were investigated.

Rio Algom previously conducted qualification tests for the Tinaja Pit rocksource in 2001, which indicated acceptable rock (Table 1). Laboratory reportsfrom Western Technologies. Inc., are contained in Appendix 1. Petrographicanalysis of the linaja Pit rock was performed by American Petrographic Services,Inc., in 2001 with the results Indicating that the rock is a massive calcitic dolomite(Appendix 2).

Based on these preliminary results for the Tinaja Pit rock, all engineeringdesign work incorporated a 4% overdesign factor to meet the NRC scoringdesign criteria in NUREG-1623.

With the development of additional erosion protection design elements atRio's Ambrosia lake facility, NRC requested Rio to requalify the Tinaja Pit rocksource to determine whether the rock quality has changed since the preliminarytesting that was conducted in 2001.

Updated rock qualification tests were conducted during the 1'1 half of2003, which confirmed that the Tinaja Pit rock continues to be acceptable foruse. Table 2 provides the summary of the 2003 test results. Appendix 3 containsthe laboratory reports. The petrographic analysis of the rock performed in June2003 resulted in similar observations/findings as the 2001 petrographic tests(Appendix 4).

Based on the two series of tests, the Tinaja Pit rock quality has improvedover time. This, combined with the 4% overdesign within the engineering, willensure that the erosion protection planned for use on the Rio Algom reclamationproject meets the 1000 year design criteria for erosion protection.

Re: Western Technologies Job No. 3241JT014APSJobNo. 10-01883

Mr. Roybal:

This report presents the results of our review of a core of carbonate rock. The sample weresubmitted to our laboratory by yourself on November 21, 2001. The scope of our work was limitedto performing petrographic testing on the sample to determine its composition.

ConclusionsBased on the work performed and previous experience, our observations and opinions are as follows:

1. The 74mm diameter by 118mm long core is of a massive, pink, fossiliferous, calciticdolomite. The pink coloration is produced by corrosion of pyrite grains, finely disseminatedin the rock

2. The carbonate is well indurated. However, dolomnitization has produced some fine porosity.Also, a single planar, pressure solution structure (stylolites) follows the length of the core.A few other discontinuous stylolites were present.

ProceduresOur work was performed on December 12,2001 and subsequent dates. The analysis was completedthrough the use of hand sample and thin section work. Observations were made in thin sectionunder an Olympus polarizing-light microscope with magnification up to 1000x and in hand sampleunder an Olympus stereozoom microscope with magnification up to 130x. The analysis includedreviewing the thin sections of the material under plane and cross polarized light conditions.Testing was performed in accordance with APS Standard Operating Procedure 00 LAB 004,"Petrographic Examination of Aggregates for Concrete, ASTM:C295'.

RemarksThe test sample will be retained for at least 30 days from the date of our report. If no furtherinstructions are received by that time, the samples may be discarded. The petrographic services forthis project have been conducted in a manner consistent with that level of care and skill exercisedby members of the profession currently practicing in this area under similar budget and timeconstraints. No warranty, express or implied, is made.

It has been a pleasure to serve you on this project. Should you have any questions on this report,please do not hesitate to call.

APS JOB NO: 10-01883 DATE: December 26. 2001

SAMPLE NO: I PETROGRAPHER: Gerard Moulzolf

HAND SPECIMEN DESCRIPTION:

A massive, pink, fossiliferous, calcitic dolomite. Euhedral to subhedral dolomite grains, generally <25Aum in size,mostly replace a coarser, anhedral, calcite matrix. The dolomitization has produced small pore spaces. Calcite fossilfragments, made up of mostly brachiopods with some rugose corals, are mostly retained. Very fine sand-sized(<0.125mm), detrital quartz grains are scattered throughout. Bedding was not discernable. Concentrations of0.125mm sized, corroded, isometric, pyrite grains occur near or within coarser calcite mosaics and drusy, sparrycalcite vug fillings. Many others are finely disseminated in the matrix, giving the rock its pink coloration. "Books"of-white clay infill several vugs or pores scattered in the sample. The quartz sand grains, corroded pyrites, and clays,i.e. insoluble residue, concentrate within a few discontinuous, and a single continuous, sutured stylolite occurring inthe core sample.

INTRODUCTION

This report presents the results of laboratory work performed by our firm on one sample of crushedcarbonate submitted to us by Ms. Deborah Hammer of Westem Technologies. Inc. on May 28,2003. The scope of our work was limited to performing petrographic analysis testing on theaggregate sample to provide a geological description of the material as well as identify anypotentially deleterious properties when it is wed foi erosion control.

TEST RSLTS

Our complete petrographic analysis test results appear on the attached data sheets. A summary ofour analysis and opinions are as follows:

I. The angular, crushedparticles ranged from equidimensional to flat and elongate. The materialwas relatively clean of rock flour.

2. The material ranged from a pinkish-brown limestone to ripinkish-tan dolomitic limestone. Thematerial contained equal amounts of both lithologieF. Fossil fragments observed in bothfossiliferous carbonates include echinoderms, brachiopods, and bivalves.

4. In general, the rock was judged to be hard, sound, and appeared durable. However, thedolomitic limestone contains significantlymore fine pore space, produced bythe dolomitizationprocess, hn the limestone.

5. We believe the carbonate material to be a good candidate for erosion control under moderateexposure conditions.

TEST PROCEDURES

Laboratorytesting was performed on Jume 10,2003 and subsequent dates. The petrographic analysiswas performed on representative hand samples and in thin section. A total of six tbin sections wereproduced from selected lithologies. Observations were made using an Olympus polarizing-lightmicroscope with magnification up to 1000x and an Olympus stereozoom microscope withmagnification up to 130x. Testing was performed in accordance with APS Standard OperatingProcedure 00 LAB 004, "Petrographic Examination of Aggregates for Concrete, ASTM:C295."

Photographs are included to illustrate our work mad conclusions.

The test sample will be retained for a periodqf at least thirty days from the date of this report.Unless firher instructions are received by t'it iane, the sample may be discarded. Potentialreactivity testing can be performed in our 1 ab,.ratones. The geologic services for this project havebeen conducted in a mnner consistent with fiat level of cae and skill exercised by members oftheprofession currernlypracticing in this area wider similar budget and time constraints. No warranty,express or implied, is made.

If we can be of further assistance to 'ou, please contact Gerard Moulzolf at (651) 659-1346 or ScottWolter at (651) 659-1345.

SAMPLE NO: Thin Sections 1, 2, and 3 PETROGRAPHER:- C. Tillema/G.Moulzolf

DESCRIPTION: Pinkish-tanbiosparite; afossiliferous, dolomitic limestone. The carbonateconsists of partiallyobscured cchinoderm, brachiopods, and bivalv a fossils with medium to coarse calcite spar inamatrix ofdolomite microspar (4mm-10,/m, #3), pseudospar (10Mum-5O~m,#2) and a mixtureof both (#1). Very finegrained, well disseminated iton oxide grains vwre observed throughoutthe dolomitized matrix. Dolomitization has produced fine porespace throughout the dolomite-rich matrix. A trace of silicificatioD was obsxved in a few microfossil cores.

A small amount of very fine sand to coarse silt-sized, detrital quartz and feldspar grains wereobserved in all thin sections. Thin, crosscutting, clear to orange-red stained calcite veinlerswere observed in the hand samples I and 2. A vein of coarse, white calcite was observed onthe outer surface of hand sample 1. Orange-red iron oxide staining was observed within thecalcite vein and many veinlets.

DESCRIPTION: Pinkish-brown calcite biospaite; a fossilferous limestone. The carbonate consists of partiallyobscured echinodermbrachiopods, and bivalve microfossils with few ooids in aporphyrotopicmatrix of calcite. Fine grained, well disseminated iron oxide grais were observed throughoutthe matrix.

A small amount ofcoarse silt-sized, detrital quartz and feldspar gins were observed in all thinsections. Thin, clear sparry calcite veinlets were observed in the thin section 6. A stylolite, asutured pressure solution structure, was observed in hand sample 6. The pink coloration ofthestylolite is most likely due to the concentration of iron oxide.

Chalcedony (chert) nodules, up to a few mm in size, occur in the cores of several microfossilgains
