This letter outlines the actions that we have taken, and that we are now committing to take, in response to this request. We c,rrently have permitting information for only one facility - Envirocare of Utah - on our web site. We have no plans to remove that information, based on previous conversations with NRC, but will do so upon your request. lnformation in our files is subject to Utah's public records law, the Utah Government Access and Munug.-"nt Act, Utah Code Ann. Title 63, Chapter 2. Under that Act, we do have the ability to withhold docurients that would present a securiry risk. Utah Code Ann. S 63-2-304(10) allows us to withhold records ,,the disclosure of which would jeopardize the life or safety of an individual." ln response to your request, we are committing to review any GRAMA request (and any other request for information) for infbrmation about a specific radioactive material licensee. If that information falls into the following .ut"gori"r, we will foiward the request to NRC for review and a recommendation about whether release of the i-nformation would pose a potential security risk and should therefore be withheld: r lnformation about facilities that use radioactive materials to sterilize products; r lnformation about facilities that manufacture or distribute radioactive sources; r Information about facilities that use sealed sources for medical Purposes;. lnformation about indusrial radiographers; . lnformation about well loggers; and . lnformation about portable moisture density gauges. t68 North t950 Wesr . pO Box 1,14850.

The DRC questions are repeated below in italics with International Uranium (USA) Corporation's ("lUSA's") responses following each question. 1. The FMRI waste pro.files indicated that the waste stream included several contaminants that have not been adequately assessed as to the cumulative ffict they may pose to the inlegrity of the pond liner, especially where the liner sections are joined. These contaminants include : 4 methyl 2-pentanone [a.k.a. methyl isobutyl ketone ("MIBK"), Bis (2- ethyl hexyl), D i - n-butyl phthal at e, c erium, hffiium, lanthanum, niob ium, ne o dymium, P r a s e o dymium, Sc andium, Sulfi de, Tantalum, Tungs ten, Yttrium, and Jluoride. Please evaluate the chemical compatibilitt o.f contaminants with the pond liner. seam int e gr it.y and qr oundw a t e r qual i t.v. Letter to Dane r. ein.Jr. |une22,2005 Page 2 iUSA has retained Jo Ann Tischler, an independent chemical engineer, to evaluate the chemical compatibility of these constituents with the Mill's tailings cell liners and liner seam integrity. A copy of Ms. Tischler's memorandum is attached to this letter. Ms. Tischler concludes generally that all of these constituents are compatible with the Mill's tailings liners and liner joints in much higher concentrations than found in the FMRI material. Accordingly, the impact of these constituents on the Mill's tailings system will be insignificant. With respect to the specific categories of constituents, Ms. Tischler reaches the following conclusions: Phthalates (e.g., bis 2-ethylhexyl and Di-n-butyl phthalate) can have a positive effect (as a plasticizer) if in high enough concentrations (approximately 30 percent). At low concentrations (part per million levels), they are de minimus and will have no impact on the liner system. The concentration of di-n-butyl phthalate, in the FMzu Material (approximately 1 ppm) is therefore de minimus and will have no impact, positive or negative on the Mill's tailings system. Bis 2- ethylhexyl phthalate is not present in the FMzu Material. There are no sulfides in the FMzu Material. Reference to sulfides in the Radioactive Material Profile Record submitted with the license amendment application was a mistake, and should have been a reference to sulfates. Sulfates at all concentrations are compatible with the aqueous sulfates already in the tailings system. As a result, the impact on the Mill's tailings system of any sulfates in the FMRI Material will be insignificant. Although there will be an increase in the overall concentration of fluoride salts in the tailings cells after tailings from processing the FMRI Material are added to existing tailings, the resulting concentration of approximately 7,200 ppm (0.7 percent) will be well below the manufacturer's ratings for compatibility with PVC of 48 percent for inorganic hydrofluoric acid and an unlimited concentration for metal fluoride salts. Accordingly, the impact of the fluorides in the FMRI Material on the Mill's tailings system will be insignificant. As the Mill's tailings cell liners are compatible with high level metallic salts, and in fact, the majority of the Mill's tailings volume is comprised of such metallic salts, no compatibility or integrity issues are expected regardless of incremental changes in the various metallic salt levels (e.g., cerium, hafnium, lanthanum, niobium, neodymium, praseodymium, scandium, tantalum, tungsten and yttrium) anticipated from processing the FMRI Material. a) b) c) d) Letter to Dane f-. P'i,r.Of. |une22,2005 Page 3 e) Under even worst-case assumptions, i.e., assumingzero values at half their detection limit and assuming no reduction in the concentration of ketones due to volatilization, the concentration of all ketones in the tailings system after processing the FMRI Material is not expected to exceed 13 ppm. This level is more than 7,000 times lower then the U.S. EPA test level for compatibility of ketones with PVC seams and is de minimus. With respect to compatibility of the referenced constituents with groundwater quality, the constituents will not have an adverse impact on the Mill's tailings system, as discussed above. Therefore, there is no reason to expect that any of the constituents will ever come into contact with groundwater. Nevertheless, in the hypothetical situation where the tailings cells are assumed to be leaking, all of the referenced constituents have either been measured to be or can reasonably be assumed to be in the existing tailings contained in the tailings cells. The concentrations of these constituents in the FMRI Material are relatively low, and, taking into consideration that the total quantity of FMRI Materials is estimated to be approxirnately 32,000 tons, compared to total existing tailings in Cell 3 of approximately one million tons, the impact of these constituents on the makeup of the tailings will be insignificant. There would therefore be no significant incremental impact on groundwater quality in the event of a hypothetical leak in the Mill's tailings cells over and above any impacts from the existing Mill tailings. 2. The waste is described as arriving in 'fabric bags". The request also describes the "dewatered sludge" as having an average moisture content of 30%. The previously submitted report titled, "Evaluation of Potential for Seepage of Constituents Present in Alternate Feed Materials into the Ore Storage Pad", dated June 28, 2002, does not evaluate material with a moisture content as high as 30o% being stored on the ore pad" Please evaluate the.fabric bags.for possible leaknge. FMRI is designing the drying process to achieve an optimal moisture content of approximately 20o/o. The 30%o moisture content was used in the license amendment application to be conservative. Based on the physical nature of the FMRI Material, it is not expected that there would be any free liquid at the higher moisture content. Even if there were some fiee liquid generated during transport or storage of the material it would be very small and totally contained by the "fabric bags". The bags are constructed of polypropylene fabric treated for ultraviolet resistance. Each bag will also have a 3 mil polyethylene internal liner for additional containment of lrigher moisture content materials. A copy of the bag specification is attached. 3. Page l2 of the license amendment request states that you may consider recovering tantalum or other metals in addition to the uranium product in the alternate feed. In the NRC memorandum "Redistribution of NRC Regulatory Issue Summary 2000-23 Recent Changes to Uranium Recovery Policy: dated April 19, 2001 ", the NRC Letter to Dane r. Pin.lt June22,2005 Page 4 includes criteriafor determining whether or not a non-natural ore can be processed as an alternatefeed. Criteria 3 states: ". . . the ore must be processedprimarilyfor its source mtaterial content. If the only product produced in the processing of the alternate feed is uranium product, this determination is satisfied. If in addition to uranium product, another material is also produced in the processing of the ore, the licensee must provide documentation showing that the uranium product is the primary product produced." Should the Licensee choose to recover uranium only, no documentation is required. Should the Licensee choose to recover any material in addition to uranium, the Licensee must notify the DRC and provide documentation that the uranium product will be the primary product pro duce d. At this time IUSA is planning on processing the FMRI Material for the recovery of uranium only. Should IUSA choose to recover any other material in addition to uranium, IUSA will notify the DRC and provide further submissions at that time. 4. The financial surety for IUSA requires that the current cost estimate be evaluated in regards to disposal process with each alternate feed and associated costs being itemized. The MarchT, 2005 report didnot address any surety costs associatedwith FMRI material, in the unlikely event that IUSA close prior to processing the material. Please provide a suret.v increase estimate. In the past, the Mill has not increased or decreased its surety amount during the year as a result of receiving or processing alternate feed materials or ores throughout the year. IUSA proposes that, consistent with past practice, the additional surety dollars to account for the disposal of the FMRI Material will be included in the revised cost estimate that will be presented to the DRC in March 2006. This makes sense for a number of reasons. Had the projected 32,000 tons of FMRI Material been at the White Mesa Mill at the time of the February 2005 surety update, the reclamation expense for the material would have added approximately $43,000 to the current estimate. However, since the material will not begin ariving at the Mill until later this year, and it is expected to take 12 to 24 months to complete delivery of the material, it would be more timely to evaluate the added reclamation liability resulting from receipt of this material in the February 2006 surety update. In the interim, IUSA is processing the Cameco alternate feed materials, which is expected to be complete by early 2006. The processing of this material will result in a reduction of the reclamation liability by approximately $73,000. IUSA does not propose that the reclamation surety be reduced in the interim to reflect this reduction in reclamation liability. Rather, it would be more appropriate to evaluate both of these activities, receipt of the FMRI Material and processing of the Cameco material, in the February 2006 surety update. Letter to Dane L.

John Hultquist, DRC Jon Jackson, FMRI Ron F. Hochstein, IUSA Harold R. Roberts, IUSA T. Kenneth Miyoshi, IUSA MEMORANDUM International Uranium (USA) Corporation Attn: David C. Frydenlund Jo Ann S. Tischler June22,2005 TO: FROM: DATE: SUBJECT: Response to UDEQ Comment Letter of 05/16/05 on FMRI Amendment Request I am supplying the following information in response to the Utah Department of Environmental Quality ("UDEQ") comment letter of May 16, 2005 regarding International Uranium (USA) Corporation's ("IUSA's") March 17,2005 application for license amendment for Uranium Material (the "FMRI Uranium Material") from Fansteel Metals Recovery, Inc. ("FMR["). This addresses the chemical compatibility of various contaminants in the FMRI Uranium Material with the Mill's tailings system, in response to UDEQ Comment #1. Comment #1 The FMRI waste profiles indicated that the waste stream included several contaminants that have not been adequately assessed as to the cumulative effect they may pose to the integrity of the pond liner, especially where the liner sections are joined. These contaminates [sicJ include:- 4 methyl 2-pentanone [a.k.a. methyl isobutyl ketone ("MIBK")J, Bis (2-ethylhexyl), Di-n-butyl phthal ate, cerium, hafnium, I anthanum, niobium, ne o dymium, P r as e o dymiu m, S c andium, Suffi de, Tant alum, Tungs ten, Yttrium, and /luoride. Please evaluate the chemical compatibili\) qf contaminants with the pond liner, seam integrit.y and gr o undw at er int e gr i fii. 1. RESPONSE 1.1.Summary The contaminants identified by UDEQ for further assessment can be categorized by chemical type as follows: (i) Phthalates - Bis 2 ethylhexyl phthalate and Di-n-butyl phthalate;(ii) Non-metal inorganic anions - sulfide and fluoride; Memo re: Response to UQ Comments Jtne22,2005 Page2 of7 (iii) (iv) As will be discussed in detail below, all of these constituents are compatible with the Mill's tailings liners and liner joints in much higher concentrations than found in the FMRI material. Accordingly, the impact of these constituents on the Mill's tailings system will be insignificant. 1.2. Tailings Liner Construction Currently, only tailings cells i and 3 are in active service. Tailings cell 4,A. is out of service and the Mill does not intend to place any additional materials in this cell unless or until it undergoes repairs and modification of its liner system. a)Cell Liners The cells were constructed with technology current for the late 1970's and 1980's. Both cells were constructed of flexible 30 mil polyvinyl chloride ("PVC"). Due to its tight polymeric structure and the intrinsic electro-negativity and chemical resistance of chlorinated super- polymers, PVC is generally selected for applications requiring impermeability to a wide range of free liquids and aqueous solutes including mineral acids, animal fats, petroleum hydrocarbons, and natural microorganisms (fungi, etc.). It was selected for use at the Mill, in part, because of its resistance both to strong sulfuric acid, and to kerosene, which are recycled through the tailings system as part of the Mill's leaching and extraction processes, respectively. b) Liner Joint Technoloey Historic information regarding the construction of cells 1 and 3 indicates that two different liner- sealing systems were used in their construction. The liner sections of one cell were j oined by the "solvent-weld" method, and those of the other by a liner-seam adhesive-bond method. The differences between the two methods are explained below. Polymer welding is used extensively to ensure joint or seam impermeability in both rigid and flexible thermoplastics, including chloro-polymers (vinyls). In polymer welding, the polymer chains at the edge or surf'ace of one segment or component are brought into contact with those at the edge of a second component and are made soft or mobile enough to entangle with chain ends from the second component. In polymer heat welding, mobility is accomplished by heating the material just above its melting temperature (for crystalline polymers) or its glass transition temperature (for amorphous polymers). When the material cools, the entangled solid mass of chains constitutes a weld. Solvent welding exposes the polyrner chains to polar organic solvents, Tlansition and rare earth metals - cerium, hafnium, lanthanum, niobium, neodymium, praseodymium, scandium, tantalum, tungsten, yttrium; and Ketones - MIBK Memo re: Responr",o ut Comments Jtne22,2005 Page 3 of7 instead of heat, to soften and entangle the strands. When the solvent evaporates, the remaining entangled solid mass of chains constitutes a weld. The liner sections of the other cell were joined by a liner seam adhesive system. This method involves applying a mixture containing strands of one or more polymers dissolved in a volatile solvent to a pair of PVC (straight, rolled or folded edge) surfaces to be joined. The solvents for both the weld method and adhesive method are ketones such as MEK, methyl isobutyl ketone ("MIBK") or blends of these and other polar compounds. Historic information for the Mill's tailings cells indicates that the ketone used both in the solvent welding method and the searn adhesive method was 2 butanone (also called "methyl ethyl ketone" or "MEK"). U.S. EPA's Hazardous Waste Engineering Research Laboratory (Morrison and Parkhill, 1987) tested 30 mil PVC seams of various widths joined by solvent adhesive and weld methods (in this case heat weld). The tests included simulated weathering and exposure to a wide range of reactive chemicals, including 10 percent methyl ethyl ketone. EPA found that both the weld and solvent adhesive joints performed satisfactorily under chemical exposure conditions. 1.3. Analysis of Categories of Constituents Found in FMRI Uranium Material a)Phthalates According to the U.S. Arrny Waterways Experiment Station (see reference 6 below), when PVC liners are exposed to multiple contaminant mixtures, the key factor in liner life and effectiveness is not chemical compatibility, but installation technique and preservation of initial plasticizer content for liner flexibility. According to the Textbook of Polymer Science (Billmeyer, l97l) two of the most common types of plasticizers and stabilizers for chlorinated polymers such as PVC since the 1960's have been di-n-butyl phthalate and multi-substituted phthalates. Polymer producers BF Goodrich, BASF Corporation, and EI du Pont recommend integration of these compounds at levels as high as 30 percent by mass into rigid PVC castings and PVC liner sheeting to improve the lifelong properties of the material. That is, exposure of the cell 1 and cell 3 linings to phthalates will not embrittle, dissolve, or degrade the liners. In fact, if present at high enough concentrations, these types of compounds would actually help maintain liner integrity by improving its plasticity, flexibility and toughness. However, at low concentrations, (part per million levels or lower) they are de minimus and will have no impact on the liner system. Bis 2 ethylhexyl phthalate is not present in the FMRI Uranium Material. FMRI characterization studies identified bis 2 ethylhexyl phthalate only in samples from Pond 5. Material from Pond 5 is not included in the material to be shipped to the Mill. Bis 2 ethylhexyl phthalate was mentioned in both the Jo Ann Tischler RCRA memorandum dated March 7,2005 and the Jo Ann Tischler chemical compatibilty memorandum (the "Tischler Technical Memorandum") also dated March7,2005, both of which accompanied the license amendment application for the FMzu Uranium Materials, as an additional example of the types of phthalates that, like di-n-butyl phthalate, can contarninate samples due to their presence in sampling equipment, containers and Memo re: Response to UII Comments June22,2005 Page 4 of7 personnel protective equipment. FMRI's NRC Site Decommissioning Plan stated that neither bis 2 ethylhexyl phthalate nor di-n-butyl phthalate were actually present in the FMRI ponds, but were reported due to their presence in plastic sampling equipment. In any case, as mentioned above, bis 2 ethylhexyl phthalate was only reported in material from Pond 5, which will not be shipped to the Mill. As the concentration of di-n-butyl phthalate in the FMRI Material, if it is actually present, is very low (approximately I ppm), it rs de minimus and will have no impact, positive or negative, on the Mill's tailings systenl. b) Non-rnetal inorganic anions (,Suffides The Radioactive Material Profile Record ("RMPR") submitted with the March 7,2005 License amendment application included a checked box indicating that sulfide was a constituent of the FMRI Uranium Material. As described in the Tischler Technical Memorandum, despite the checked box on the RMPR, there is no data in any of the laboratory results indicating the presence of any sulfides in the FMRI Uranium Material. The laboratory reports do indicate the presence of sulfates, which are entirely compatible with the aqueous sulfates already in the tailings system, as addressed in the memorandum. IUSA has confirmed via a June 10, 2005 telephone contact with FMRI that the sulfide box in the RMPR was checked off in error. IUSA is in the process of obtaining an updated RMPR, corrected to indicate sulfate, not sulfide, content, and will submit that document to the UDEQ separately from this response. As sulfates in any concentrations are compatible with the aqueous sulfates already in the tailings system, the impact of any sulfates in the FMRI Material will be insignificant. (i, Fluorides Information from FMRI indicated that fluoride was present in the FMRI Uranium Material only in inorganic forms. As described in the Tischler memorandum, the FMRI Uranium Material consists mainly of residual metal impurities in the fluoride form, that is, metal fluoride salts. Fluorides have been introduced into the Mill's uranium circuit with natural ores and alternate feeds at levels as high as 460,000 mg/kg. The FMRI Uranium Material was estimated to have an order-of-magnitude average concentration of 309,000 mg/kg fluoride salts. Various manufacturel's literature rate flexible PVC as resistant to inorganic hydrofluoric acid at concentrations as high as 48 percent by weight, and resistant to metal fluoride salts in all proportions. Although there will be an increase in the overall concentration of fluoride salts in the tailings cells after FMRI tailings are added to existing tailings, the resulting concentration of Memo re: Response to U] Comments June 22,2005 Page 5 of7 approximat ely 7,200 ppm (0.7 percent) will be well below the manufacturer's ratings of 48 percent for inorganic hydrofluoric acid and unlimited concentrations for metal fluoride salts. Accordingly, the impact of the fluorides in the FMRI Material on the Mill's tailings system will be insignificant. c) Transition and Rare Earth Metals Various manufacturer's literature rate flexible PVC as resistant to metallic salts, metallic soaps, metallic cyanides and metallic acetates in nearly all proportions. This resistance includes compounds of the alkali metals, the alkaline earths, the rare earth metals, the transition metals, and the metalloids. For this reason, PVC has been used extensively for piping, tubing, bulk containers and flexible system liners for aqueous solutions of these compounds for nearly three quarters ofa century. As the Mill's tailings cell liners are compatible with high level metallic salts, and in fact, the majority of the Mill's tailings volume is comprised of such metallic salts, no compatibility or integrity issues are expected regardless of incremental changes in metallic salt levels anticipated from processing the FMRI Uranium Material. d) Ketones Methyl isobutyl ketone could be expected to be present in the FMRI Uranium Material as a residual from FMRI processing steps. Ketones are already present in the current tailings composition due both to their use in small quantities in the Mill's on-site laboratory and their presence at low levels in some previously processed alternate feeds. Manufacturer's guides indicate that ketones may be incompatible with PVC liner systems under some conditions. These conditions include: . high concentration solutions of ketones, . non-aqueous solutions of ketones (such as mineral oil or plant oil based solutions), and . direct contact of dry liner surfaces with free product ketone. As described earlier, U.S. EPA obtained satisfactory results from liner and joint testing of PVC with ketone solutions at concentrations up to 10 percent. Calculations in Table 2 of the Tischler Technical Memorandum indicate that based on the most conservative assumptions, the overall average MIBK concentration in the FMRI Uranium Material might be estimated to be 4.1 ppm, and the total ketone concentration in the Mill tailings after processing FMRI Uranium Material might be estimated to be 13 ppm. The estimates are overly conservative for two reasons. First, they assigned a quantity of half the detection limit to every reported zero value in the FMRI data for any ketone. Second, they assumed that the concentrations of these highly volatile compounds would not be reduced by evaporation during Memo re: Responr",o uO Comments June 22,2005 Page 6 of7 FMRI handling, shipping to the Mill, storage, Mill processing or at any time from the tailings evaporation cells. In addition, for conservatism, the Mill takes additional measures to minimize the exposure of the cell liners to potentially degradative conditions. Tailings from alternate feeds and Mill laboratory wastes containing trace ketones have only been pumped to cells actively in use and already containing large volumes of aqueous solutions. No oil-based mixfures of ketones have ever been disposed in the cells. Ketones have no opportunity for direct contact with a dry cell liner or liner joint surface. Under even worst-case assumptions, i.e., assumi ngzerovalues at half their detection limit and assuming no reduction in the concentration of ketones due to volatilization, the concentration of all ketones in the tailings system is not expected to exceed 13 ppm. This level is more than 7,000 times lower then the U.S. EPA test level for ketones and is de minimus. 2, SUMMARY OF CONCLUSIONS 2.1. Phthalates can have a positive effect if in high enough concentrations (approximately 30 percent). At low concentrations, (part per million levels) they are de minimus and will have no impact on the liner system. The concentration of di-n-butyl phthalate in the FMRI Material (approximately 1 ppm) is de minimus and will have no impact, positive or negative on the Mill's tailings system. Bis 2-ethylhexyl phthalate is not present in the FMRI Uranium Material. 2.2. There are no sulfides in the FMzu Uranium Material. Reference to sulfides in the RMPR was a mistake, and should have been a reference to sulfates. Sulfates at all concentrations are compatible with the aqueous sulfates already in the tailings system. As a result, the impact on the Mill's tailings system of any sulfates in the FMRI Uranium Material will be insignificant. 2.3. Although there will be an increase in the overall concentration of fluoride salts in the tailings cells after tailings from processing the FMRI Uranium Material are added to existing tailings, the concentrations of approximately 7 ,200 ppm (0.7 percent) will be well below the manufacturer's ratings of 48 percent for inorganic hydrofluoric acid and an unlimited concentration for metal f'luoride salts. Accordingly, the impact of the fluorides in the FMRI Material on the MilI's tailings system will be insignificant. 2.4. As the Mill's tailings cell liners are compatible with high level metallic salts, and in fact, the majority of the Mill's tailings volume is comprised of such metallic salts, no compatibility or integrity issues are expected regardless of incremental changes in metallic salt (e.g., cerium, hafnium, lanthanum, niobium, neodymium, praseodymium, scandium, tantalum, tungsten and yttrium) levels anticipated from processing the FMRI Uranium Material. 2.5. Under even worst-case assumptions, i.e., assumingzero values at half their detection limit and assuming no reduction in the concentration of ketones due to volatilization, the Memo re: Respons" to uO Comments June 22,2005 PageT of7 concentration of all ketones in the tailings system is not expected to exceed l3 ppm. This level is more than 7,000 times lower then the U.S. EPA test level for ketones and is de minimus. 3. REFERENCES 1. Billmeyer, Fred. W. Textbook of Polymer Science, Second Edition. New York.

RML # SUA 1358 Dear Mr. Frydenlund: The purpose of this letter is to notify you of the current fee schedule for source material licensees. Pages 217 and 220 of the State of Utah "Appropriation Act", Senate Bill No. 1, relating to fees to be charged to source material licensees, are provided as a references. This bill was effective July r.2004. The fee schedule takes into account three states of licenses: l) an active facility licensee, 2) a licensee whose facility has been deemed to be in "standby" condition and 3) a licensee undergoing reclamation and decommissioning. As an active license, the "S.B.1" fee schedule authorizes a fee of $6,667.00 per month and a "review fee" of $70.00 per hour. Our approach is to apply the $70.00 per hour assessment only to permitting /licensing activities. All staff compliance activities such as inspections and follow-up, Division managerial, secretarial, rule making, and budget support costs associated with lle(2) licenses will not incur the $70.00 per hour fee. As a matter of business practice, the Division will send a statement to you on the 15th day of each month for the payment due by the l5th day of the next month. According, please accept this letter as notice of your payment due for the month of October and remit payment by October 15,2004- 168 North 1950 West . PO Box 1,14850 .

Walker, have signed an Agreement regarding certain radioactive materials. The Agreement transfers NRC's regulatory authority with respect to the possession, use and disposal of 11e.(2) byproduct material las defined in Section 11e.(2) of the Atomic Energy Act of 1954, as amendedl and the facilities that generate such material, to the State of Utah for licensing, inspection, and rulemaking activities. The Utah Department of Environmental Quality (DEQ), Division of Radiation Control (DRC), is now responsible for implementing the lle.(2) byproduct material disposal and uranium milling program for the State of Utah. ln order to ensure that the program developed by the State of Utah meets the requirements and is compatible with the NRC's program in all other respects of the Atomic Energy Act to protect public health, safety and the environment, the Utah Radiation Control Act and Utah Radiation Control Rules have been modified to incorporate requirements for uranium milling and 11e.(2) byproduct material management. Also, you should be aware that the Radiation Control Board (Board), a Statutory Board, was created to guide the development of State radiation control policy and regulations implementing the Radiation Control Act. Although the Board is responsible for issuance of all radioactive material licenses, they have delegated to the Executive Secretary the authority to issue licenses, issue orders, conduct inspections, and to enforce compliance with regulations, license conditions, and orders. 168 North 1950 West .
