C. RECOMMENDATION April 18, 1978 2. It is the opinion of the Planning Commission that before Wyoming Mineral Corporation is issued a Special Use Permit for full production uranium solution mining in Weld County, restoration of the groundwater affected by the ISL-1 method should be accomplished to the satisfaction of the Board of County Commissioners . Further, it is the opinion of the Planning Commission that an application for full production solution mining can be made concurrently with the testing of the ISL-2 method. However, before full production solution mining can begin restoration of the groundwater effected by the ISL-2 method should be accomplished to the satisfaction of the Board of County Commissioners. The Planning Commission recommendation for approval is subject to : A. Development Standard #1 being approved as submitted by the applicant. B. Development Standard #21 being amended to read: Restoration of the groundwater affected by the originally designed tests which utilized an ammonium bicarbonate lixiviant now termed ISL-1, as authorized under SUP-303 : 76 : 8, shall be accomplished to the satisfaction of the Board of County Commissioners prior to the issuance of further Special Use Permits to conduct uranium solution mining in Weld County. Restoration of the groundwater affected by the herein approved test, which utilizes a calcium bicarbonate lixiviant now termed ISL-2, shall be accomplished to the satisfaction of the Board of County Commissioners as a condition of and prior to injection of any foreign substances or lixiviant in any approved uranium solution mine in Weld County. Surface reclamation shall be accomplished to the satisfaction of the Board of County Commissioners after completion of all tests including those authorized under this amendment . Restoration of groundwater shall be complete but flexibilities shall be considered with regard to completeness of surface reclamation in view of seasonal considerations and future operations. s GEA-78-1151 Wyoming Mineral 3900 Sc Wadsworth Blvd Corporation Lakewood, Colo 80235 A Subsidiary of Westnghouse Electric Corporaton September 7, 1978 Mr. William S.

Restoration Testing 1.0 GROVER SLUG TEST RESTORATION DEMONSTRATION A slug test was performed at WMC's Grover, Colorado, Site in early 1977 in which a slug of 4,000 gallons of ammonium bicar- bonate lixiviant was injected into a single hole, allowed to remain in the formation for a period of 24 hours, and then withdrawn. Additionally, as part of a demonstration of ground- water restoration, an additional four slug volumes were with- drawn and treated to observe the efficiency of groundwater sweeping methods for restoration of this slug test. The results of this test, as summarized in the table below, indicate that restoration of all ions, with the exception of U308, was achieved using this technique.

WADSWORTH BLVD. LAKEWOOD, COLORADO 80235 I. GROVER RESTORATION DEMONSTRATION PROGRAM A. Introduction Wyoming Mineral Corporation has completed an initial evaluation of in-situ uranium mining at the Grover, Colorado test site in Weld County. This evaluation consisted of three test programs outlined below. 1. Grover Slug Test - Purpose of this test was to scope the leaching and restoration characteristics of the Grover sand. 2. Well-Field 1 Leach Test - Purpose of this test was to provide the economic and process information required to design a full scale uranium solution mining facility. 3. Well-Field 2 Leach Test - This test was mobilized to incorporate changes in well field installation methods. After an initial test period using an ammonium bicarbonate leaching agent, a mining/restoration test using a calcium bicarbonate leach chemistry was made. As part of the evaluation, groundwater, affected by the leach solution used in the mining process, is being restored to acceptable water standards prior to site reclamation. WMC has completed the slug test restoration and is currently involved in a restoration project that will restore the affected test areas, Well Field 1 (WF-1) and Well Field 2 (WF-2) (see Figure 1) . The current status of these tests is outlined below. The restoration program consists of three techniques considered most desirable for use at the Grover site. These are: (1) Clean Water Recycle (2) Chemical Treatment combined with Clean Water Recycle (3) Residual TDS Reduction The clean water recycle test started on May 13, 1978 and concluded on July 5, 1978. Clean water recycle consisted of removal of the contaminated water from the aquifer, purification using a technique such as reverse osmosis and reinjection of the purified water. When this technique was used on the Grover site, the NH4+ level equilibrated at approximately 100 mg/1 and the decision was made to proceed with chemical treatment combined with clean water recycle in order to reach a lower NH4+ equilibrium value. At present chemical treatment combined with clean water recycle is being conducted and will be followed by Residual Total Dissolved Solids (TDS) Reduction. B. Baseline Water Quality Baseline water quality data for the Grover field is shown in Tables 1 and 2. The data shown represents the average of 12 analyses (4 samples each from WF-1 recovery wells G-1, G-2 and G-3) . These samples were collected over a one month period (June 1977) prior to the initiation of mining.

Due to problems in well field hydrology, and well field completion, difficulty was encountered in solution mining of WF-1. A second well field (WF-2) located southeast of WF-1 was completed, and the solution mining test was continued.

A small-scale restoration test utilizing a six-spot pattern in WF-1 was run between November 1977 and February 1978. The 6 gpm clean water sweep restoration plant recovered -", 77,000 gallons of clean water. The clean water sweep test consisted of recovering contaminated water purification by a reverse osmosis unit, followed by injection of the treated water back into the well field. Results of that test were submitted in the February 7, 1978, Grover Restoration Status Report. Start of the full-scale restoration program was initiated in March 1978, but significant progress was not achieved until May 31, 1978, because of some aboveground process problems. The process that was used utilizes a Clean Water Recycle Technique in which water is removed, treated for contaminant removal, and reinjected into the formation. This method is highly desirable in that a high degree of water conservation can be realized. Only a small-volume bleed stream containing the removed impurities is wasted, and the remaining clean water is restored to the mined acquifer. Two Reverse Osmosis units were used to conduct this test. Computer hydrology modeling of the restoration well fields was performed in order to optimize the expected acquifer clean-up. It was determined that three pumping phases would be required toachieve the most desirable rate. Plots of the streamlines and swept areas for each phase are included in Figures 2 to 5. Restoration Process Operation: The Clean Water Recycle technique, shown in Figure 6, for restoring the Grover wellfield consisted of: 1. Recovering water from the leached wellfield from the designated wells. 2. Acidification of the recovery water either by HC1 or H2SO4 and decarbonation of the acidified water (pH 4.0 to 5.0) to remove CO2 gas. This is accomplished by recirculating the water in the feed tank through spray nozzles. 3. Cleaning the decarbonated recovery well water by two reverse osmosis units. The primary R. 0. unit with a capacity of producing 40,000 gallons of permeate operates in conjunction with a 10,000 gallon per day Ni rigure L 4r -G fik ay.c \ .fir \ G�R- / i/ \ ii-Fv / \i \ e/ i G-5 , ,'\ \ / \ 0_1c,•Ic \ / \ . ` /\ L \ \ - '6-3\ ,jrc, z k LP.

Because of the re- stricted brine storage capacity, the secondary R.O. unit treats the brine from the primary unit to recover additional clean water. The permeate (clean water) from the secondary R.0 unit is recirculated to the injection surge tank for injection. 4. The clean water from the R.O. units is treated to raise the pH to 7.0 - 7.5 and injected to the desig- nated injection wells. the pH adjustment of the injection solution is made by addition of Ca(OH)2. The major ion analysis of the WF-1 recovery well water collected on Phase I termination date com- paring with post-mining and baseline values are shown in Table 6.

At that time, the concentration of NH4+ had reached a steady drop to about 100 ppm. In order to enhance the rate of ammonia removal, a chemical restoration method was used. The technique being used for chemical restoration consisted of increasing the Ca concentration in the recirculating restoration solutions, thus causing a shift in the cam/NH4+ equilibrium which tends to elute NH4+ from the clays. Since approximately July, the Ca++ concentration of the injection solution has been increased to 1,000 mg/1 in approximately 250 mg/1 stages. The Ca++ has been added as CaC12 and the pH has been held constant at 9. 1 + 0. 1. The Ca concentration in the recovery solution did not increase significantly until August 16, 1978, when it increased from 60 mg/1 in the recovery solution to approximately 90 mg/1. An expected increase in NH4+ was also noted from approximately 120 to 160 mg/1. Table 7 shows the current relationship of the Ca++/NH4+ in the restoration recovery solution. TABLE 7 Ca++/NH4+ Concentrations in Chemical Restoration Test Date NHL, Ca++ mg/1 mg/1 August 21, 1978 163 158 August 20, 1978 158 132 August 19, 1978 160 No Analysis August 17, 1978 148 94 m The data shows the Ca is continuing to increase while the NH4+ appears to have reached an equilibrium value. Based on this data, the decision has been made to return to Phase I of the pumping pattern in order to assure complete contact of the entire field with the high Ca++ solution. This will enable elution of NH4+ from areas not completely contacted with the Phase II pumping pattern. After switching to Phase I, con- tinued elution of NH4+ will be performed until a decrease in the equilibrium value is observed. At that time, the Ca++ addition will be terminated and conventional clean water recycle will again be initiated. 4.0 PROGRAM CONTINUATION It is anticipated that the Phase I chemical elution will continue for approximately two weeks or until the NH4+ concentration in the recovery solution decreases. After the NH4+ elution has been completed, residual TDS will be reduced using the clean water recycle technique. It is anticipated that the completion of the Grover restoration project will be terminated within 60 days, at which time stability monitoring of the well field will be started. r RESTORATION STANDARDS DEVELOPMENT August 22, 1978 WYOMING MINERAL CORPORATION 3900 S. WADSWORTH BLVD. LAKEWOOD, COLORADO 80235 WMC GROUNDWATER RESTORATION CRITERIA SUMMARY Restoration Criteria 1. Return groundwater to acceptable drinking water standards or average baseline consistent with initial projected water use. 2. Return ammonia to levels consistent with public health and safety. A level in the range of 20-50 ppm is consistent with this criteria. Groundwater Impact Mitigation 1. Return all constituents to acceptable standards for public health and safety. 2. Natural clean-up of ammonia due to clay absorption. Natural reduction of ammonia levels with time. 3. Effect of residual ammonia on potential future water use. • Beneficial impact on irrigation use ▪ No impact on livestock water use ▪ No health effects for domestic or water supply use (i) Municipal water use - no impact (ii) Local rancher use - no impact (iii) Mine zone water use - due to the natural presence of the uranium ore body the water is unfit for domestic or livestock use; residual ammonia at levels consistent with public health and safety. There have been no groundwater standards established by any authority pertinent to the Grover Test Site in Weld County, Colorado. As the mining test has been completed and restoration of groundwater quality has been initiated, pertinent evaluations, authoritative papers and analogous regulations have been issued by such Federal Agencies as the Environmental Protection Agency, Food and Drug Administration and Nuclear Regulatory Commission. These now establish a credible basis from which to establish a reasonable standard for restoration of groundwater quality. A. Federal Evaluation of Groundwater Impact and Restoration Standards. Groundwater standards are, for the most part, not available for various groundwater sources. Certain criteria or general guidelines have evolved in the past year which can be the basis upon which to develop site or project specific solution mining groundwater restoration criteria. The most definitive environmental assessment of a solution mining operation is that which has been prepared by Oak Ridge National Laboratory (ORNL) for the Nuclear Regulatory Commission (NRC) on WMC's Irigaray Project in Wyoming. The Environmental Impact Statement for that project (NUREG-0399) has been carefully reviewed by the NRC, EPA, Department of the Interior, the State of Wyoming and various other state and federal agencies. A summary of these agencies review of the solution mining process is given on the attached summary page as it applies to groundwater restoration. ATTACHMENT 1 NRC DRAFT ENVIRONMENTAL IMPACT STATEMENT (DEIS) A summary of the NRC position, taken from the Irigaray Solution Mining DEIS, is given below. Overall NRC Position "After weighing the environmental, economic, technical and • other benefits of the Irigaray project against environmental and other costs and considering available alternatives, the action called for under NEPA and lOCFR51 is the issuance of a source material license to the applicant." NRC Position on Solution Mining It is an environmentally attractive alternative to conventional mining, when applicable. ▪ It provides economical secondary grade resource recovery. NRC Position on Groundwater Impact • Mining zone water is unfit for domestic or livestock use. Consumptive use of water is low. Restoration will return water to acceptable levels consistent with health and safety. NRC Position on Residual Ammonia "No significant risk to mammals from the ingestion of water containing this (i.e. , 20-50 ppm) concentration of ammonia". Ammonia will be immobile and remain in the mining zone. Ammonia conversation to nitrates appears unlikely under the conditions found in the aquifer. Risk of a small residual ammonia is acceptable: (i) The small area of impact (ii) Unfitness of mining zone water for domestic and livestock use. (iii)Monitoring program will insure understanding and control of any future impact. B. EPA Position on Solution Mining A summary of the EPA position on solution mining is summarized in the attached letter on their review comments on the NRC DEIS (see attached letter from EPA to NRC) . In summary, the EPA has determined that, "According to the procedures EPA has adopted to rate environmental statements, NUREG-0399 will be listed in the Federal Register as LO-2. This means that based on the information presented, we have no environmental objection to the limited five year project, but request some additional information be presented." A recent final ruling by the EPA on Effluent Limitation Guidelines for Existing Sources (Federal Register, Vol. 43, No. 133, July 11, 1978, page 29771) has taken the position of BPT (Best Practical Technology) for uranium mines and mills persuant to Sections 301 and 304 of the Federal Pollution Control Act (33 U.S.C. 1311, 1314) . The guidelines for the Uranium, Radium and Vanadium Ore sub-category is as follows. "The concentrations of pollutants discharged from mills using the acid leach, alkaline leach or combined acid and alkaline leach process for the extraction of uranium, radium and vanadium including mill-mine facilities and mines using in-situ leach methods shall not exceed:" Effluent limitations Effluent Average of daily Characteristic Maximum for values for 30 any 1 day consecutive days shall not exceed- Milligrams per liter TSS 30 20 COD 500 As 1.0 .5 Zn 1.0 .5 Ra-226*(dissolved) 10 3 Ra-226*(total) 30 10 NH3 100 pH Within the range 6.0 to 9.0 *Values in picocuries per liter (pCi/1) .

In general , the EPA reviewing staff found the DES to be a thorough and well prepared document. We strongly support the NRC's phased-develop- • - . ment approach during th first five years which limits the size of the - - operation o 50 acres un it restoration is demonstrated on a production- scale minin n-ice.--The' RC's licensing approach to the Irigary Project seems a reasonable action that will set a positive precedence for future - in-situ solution mining projects. Regarding the restoration question, we are concerned with the residual ammonia in groundwater or absorbed to clay particles in the - aquifer after mining. The applicant's ability to remove this con- taminant to an acceptable level is still open to some doubt as is the fate of the ammonia which can be converted to nitrate (NO3) under given conditions. Since there are strict EPA limitations on nitrate in drinking water due to its public health implications , we urge the NRC - to exert the utmost vigilance in evaluating the applicant's restoration program and its results. Before any additional solution mining is authorized in adjoining sections, the NRC staff should get a consensus agreement from involved Wyoming State Agencies and EPA that any further degradation of groundwater is within acceptable limits:' In this DES, as in other recently issued statements, the NRC staff has stated that the source material license will be contingent upon the acceptance of the applicant's emergency action plan for yellow- - cake transportation accidents. Since the EPA Region VIII office has a dedicated interest in this area, as evidenced by the staff's involvement in the NRC supported publication "Guide and Example Plan for Development of State Emergency Response Plans and Systems for Transportation-Related - ATTACHMENT 2 (continued) 2 Radiation Incidents", we request that the Region VIII office be given the opportunity to review the applicant's plans and the NRC staff's acceptability criteria. According to the procedures EPA has adopted to rate environmental statements, NUREG-0399 will be listed in the Federal Register as LO-2. This means that based on the information presented, we have no environ- mental objection to the limited five year project, but request some additional information be presented. We will be glad to discuss the attached comments if you need further clarification or desire additional guidance on how these can be dealt with in the final environmental statement. Sincerely yours, 93-D- Alan Merson • Regional Administrator • Enclosure • C. Wyoming Department of Environmental Quality (DEQ) The Wyoming Department of Environmental Quality has established that groundwater restoration would be to "Average Baseline or EPA Drinking Water Standards, whichever is higher." In addition, for NH4+, for which there is no accepted drinking water standard, the level has been set in the range of 20-50 ppm. Table C.1 shows the criteria selection for the Irigaray Project. D. Colorado Groundwater Standards Committee A Groundwater Standards Committee has been at work in Colorado to formulate standards on various groundwaters and potential pollution sources. A summary of their current position is given in Attachment 4. Of importance is comment 11, which supports the concept of limited degradation not beyond accepted water quality standards. "Degradation of groundwater up to given limits of concentration of selected constituents may be allowed; of concentration already above the standard limit, no further degradation should be allowed." E. Food and Drug Administration (FDA) Ruling on Acceptable Levels of NH4+ Compounds as Food Additives A recent ruling by the FDA on generally accepted as safe (GRAS) levels for food additives (Federal Register, Volume 43, April 4, 1978) indicates that NH4+ compounds are commonly used as food additives. A summary of the allowable levels of ammonium compounds that can be safely added to commonly consumed foods is shown in Attachment 5. The toxicological study in support of this ruling ("Evaluation of the Health Aspects of Certain Ammonium Salts as Food Ingredients", NTISI, PB-254-532, October, 1974) clearly shows that: a. Ammonia compounds such as ammonium bicarbonate has been safely used as food ingredients since 1902. b. The projected range of consumption of ammonium compounds for adults ranges from several hundred mg to several thousand mg. c. The joint FAO/WHO Expert Committee on Food Additives has concluded that "there appear to be no toxicological grounds to limit" the use of ammonium bicarbonate, ammonium carbonate, and ammonium hydroxide when used in accordance with good manufacturing practice (13) . In general, it has been found that the ammonium ion is safely consumed by man and mammals at levels much in excess of the proposed level of 20-50 ppm.

Basic Principles of Regulation 1 . Regulations should strive for equity to all . 2. In harmony with maximum beneficial use of the total water resource. 3. Recognize physical differences in occurrence, natural recharge , movement, natural quality, treatment capacity, uses between separate aquifers and also within a single aquifer (confined, unconfined; perched). The geologic and hydrologic characteristics of the aquifers and the movement of water are so different in each that special attention is required for each , 4. Regulation should allow administrative discretion in setting conditions on discharges to groundwater because of the durability in hydrogeology and in changing conditions of withdrawals. 5. Regulation should not interfere with exercise of legal water rights , nor place an additional financial burden on water right owner (burden should be on effluent discharger) . 6. Recognize surface-groundwater interaction where aquifer is hydraulically connected to surface stream. ' 7. Recognize special problems in cases where aquifer is being depleted. 8. Well construction standards for pollution control should be included in regulation if existing regulations are not enforceable or enforced. (Drinking water act; well permits of state engineer, etc. ). 9. Non-active sources of groundwater pollution should be controlled by regulation (mineral exploration holes, abandoned wells) . 10. Relative authority and responsibility of State Engineer, Oil and Gas Commission, Groundwater Commission and Division of Water Quality Control should be defined. 11 . Degradation of groundwater up to given limits of concentration of _ �� selected constituents may be allowed; of concentration already above the standard limit, no further degradation should be allowed. 12. Should deal only with man-induced sources. 13. Best management practice (BMP) may be best approach to discharges not capable of regulation (certain pond seepage) . 14.

Wyoming Mineral Corporation held an Open House presentation at the Denver-Hilton for Colorado legislators and government officials on November 3, 1977, and at the Winterset Inn in Greeley on November 4, 1977 for our Weld County neighbors. The presentation consisted of a slide presentation on solution i mining and specifically, our activities at our test facility near Grover, Colorado were discussed. . A Solution Mining Workshop was held in December where the Corporation disseminated basic information on the in-situ mining technology to technical and professional personnel from the Colorado, Wyoming and Montana regulatory and environmental agencies. WMC also participated in the 81st National Western Mining Conference in Denver in early February with an exhibit on solution mining. These provided opportunities to discuss WMC's activities and to achieve better public understanding of 11 the project. Power Resources Corporation has been actively cooperating with the Forest Service's District Ranger of the Pawnee Grasslands in working on the environmental aspects of exploratory and mining operations. WMC also has actively participated in the Forest Service's RARE II Program, advocating a well-rounded wilderness program encompassing the multiple use concept. I . Wyoming Mineral Corporation contributed $500 to the Denver Audubon Society in April to help start their Grover Wildlife Center Project. The old railroad station at Grover is to be converted to a laboratory and study center for visiting scientists doing research on the Pawnee Grasslands; dedication will be August 18. . The Weld County Board of Commissioners, on May 24, 1978, granted an extension to July 1, 1979 of the Special Use Permit for the Grover site to allow additional testing. WYOMING MINERAL CORPORATION-GOVERNMENT AND ENVIRONMENTAL AFFAIRS • 3900 So.Wadsworth Blvd.Lakewood,Colorado 80235 ,.,_IIIEMNIM.N...r I RECENT EVENTS, CONTINUED. . . New Production Facility: Wyoming Mineral Corporation is preparing an application for a Colorado Department of Health Subsurface Disposal Permit for a full production facility to be built in Weld County. Various geohydrological data are being gathered in the Keota area to determine baseline groundwater quality, aquifer characterization, and ore body definition. Biological, archaeological, and socio-economic surveys have been initiated in the area. Numerous meetings have been conducted with the State and County regulatory agencies to discuss data needed by them and to outline WMC's approach in applying for a full production _ license. A An application will be submitted to the Weld County Planning Commission and the Weld County Board of Commissioners for a Special Use Permit. Applications also will be submitted to the State Engineer's Office, the Mined Land Reclamation Board, and several other state agencies in the coming months in compliance with Colorado's laws. Government Interfaces: • In response to concerns expressed by local residents over the exploratory drilling program, Wyoming Mineral Corporation escorted a member of the Colorado Agricultural Council around the Grover Test Site and the field studies near Keota to demonstrate Powerco's sound drilling program. 11 • A Colorado Division of Mines representative visited the Grover site to conduct an inspection and make an annual report on our activities. A member of the Weld County Planning Commission staff also made an inspection visit to Grover. • Wyoming Mineral supplied data and information in support of Governor Lamm's recent special survey on energy activity in the State of Colorado. ▪ Erich W. Tiepel, Manager of Environmental Projects for Wyoming Mineral, accepted an appointment to sit on a special committee organized to draft new regulations for the Colorado Department of Health for protecting the state's groundwater resources. ▪ Members of the Colorado Board of Land Commissioners and representatives of the Denver Water Board, the City of Aurora, the City of Thornton, and Park County toured the Grover Test Facility on June 23rd in preparing for deliberations about making certain state lands available for bidding on leases. RECENT EVENTS, CONTINUED. . . ► Other News: At the Colorado School of Mines Engineers' Days, April 7 & 8, 1978, WMC's exhibit of in-situ solution mining of uranium won second prize for quality of presentation. Wyoming Mineral Corporation and Power Resources Corporation both continue to be concerned about any unplugged exploration wells left by earlier exploration companies. More than two years ago, a reward of $5.00 was offered for each unplugged well reported near the WMC/Powerco operations. Just two wells have been reported, and they were plugged promptly. The offer still stands. If you have one to report, contact the WMC Project Manager, Bill Kauffman (phone - 221-5700 in Fort Collins) . i 1 _ _ THE P,\ NEE PROJECT - IN THE BEGINNING . . . In the mid - 1960's, Robert V. Bailey, - a geologist, who is now President of ' Power Resources Corporation (Powerco) 't1 iwas examining water well sample descriptions at the State Engineer's office in Denver, as part of a search for coal deposits in the Denver Basin. His search encompassed more than 45,000 logs of wells in parts of Larimer and Weld Counties. Mr. Bailey noticed that the descriptions from one particular well in eastern Larimer County, north of Wellington, reported "yellow, pink and white sand" about 300 feet 4below the surface. Being aware that such colors often exist in sandstones which contain Powerco Officials: Robert V. Bailey & Milton Childers luraniu„ deposits, he made a mental Inote of the description. Not until } 1970, after he had formed Aquarius jResources, did :Ir. Bailey visit the lwell in the field for a first-hand I ;r2 i "3 ) examination. In some of the dry washes north of Wellington, he found ! i Icolors and other characteristics in the Fox Hills Sandstone which definitely indicated that uranium • bearing solutions had been active in the area during geological ages past. t i Plugging an Exploration H 1, #4 I , , I I I ' 1 I ----- - The Exploration Drill Rig Dennis Yakobson, Vice President, Land, Powerco { #5 ' Leasing from free mineral owners and from the State of Colorado was initiated, and Power Resources I i Corporation joined ','ith Aquarius as an equal equal partner. Later, ' continuing geological work revealed ! uranium potential scattered over a i I large area from Wellington on the west to New I:aymer on the east, and 1 ) from 3riggsdale on the south to the 1 Wyoming-Colorado border on the north. , ' Powerco and Aquarius proceeded to obtain additional state and fee uranium leases in the area, but, as i small companies, they were well — aware that large dollar expenditures Powerco's Exploration Team in the Field ` were necessary to carry out all the drilling, testing and licensing that must precede production. Such procedures often require several #6 #8 t years to complete, and, in the ; meantime, annual lease rental 1 paments to various mineral owners 1 had to be maintained. Staking a Well Location Examining Well Cuttings #10 I l Powerco and Aquarius then presented their "Pawnee Uranium Project" idea to various companies in the uranium exploration business. Wyoming Mineral Corporation agreed with Powerco and Aquarius that the area appeared 1 to have potential for uranium deposits, and a joint-venture was worked out among the three companies. Wyoming Mineral Corporation was { to earn an interest in the' project by the r expenditure of funds for exploration drilling, leasing, lease rentals , and development testing 1 I I I e The Completed Well -..... _ ,.-_......._a._..= ....- W OMING MINERAL CORPORATION. . . #9 is a wholly-owned subsidiary of Westinghouse Electric Corporation. Wyoming Mineral originally began as a joint-venture with Homestake Mining Company in 1967 near Casper, Wyoming. When 3 athe joint-venture dissolved in 1974, Wyoming Mineral moved it's headquarters operation to j Lakewood, Colorado. Here it continued to carry on exploration activities on properties Iacquired as a result of the joint-venture, 1 in addition to acquiring new responsibilities 1 which included the "Pawnee Uranium Project". The Corporation's activity at this time focuses on the acquisition and development of uranium by solution mining and other 4 nonconventional extractive techniques. The j Corporation has several production and ti testing facilities in current operation. Two full-production facilities are located in Texas, and a full-production facility is under development north of Casper, Wyoming. Facilities for extracting uranium from copper-leaching solutions and phosphate processes are in advanced stages of completion in Utah and Florida. Aerial View of the Grover Test Site TAE GOVERNMENT AND ENVIRONMENTAL AFFAIRS DEPARTMENT I - As operating partner, Wyoming Mineral Corporation is involved with the acquisition of the appropriate permits and licenses for the project. ) This responsibility is in the hands of the Government and Environmental -Affairs Department, originally called the Licensing Department. As their charter expanded to include radiation and industrial safety, 999 public acceptance programs, environmental and restoration engineering studies, regulatory and legislative analyses and permit compliance auditing, it became necessary to create three sub-groups for smooth and efficient handling of these activities. As a result of this expansion, State and Federal Licensing Groups and an Environmental Projects Group were formed under the Government and Environmental Affairs Department. In addition to obtaining the necessary licenses and permits, it is the responsibility of the Department to ensure that the conditions of the permit are carried out and complied with. The Government and Environmental Affairs Department also is responsible for carrying out radiation and field safety activities, specific environmental testing and monitoring projects and scientific research studies in support of license and permit applications. The expertise within the Government and Environmental Affairs Department includes the special fields of geology, hydrology, biology, health Iph'-sics , economics and law.

Colorado Dear Mr. Fortner: The dissolution of the joint-venture partnership of Wyoming Mineral Corporation with Power Resources Corporation and Aquarius Resources Corporation was announced publicly today, effective March 19, 1979. The mutual termination of the agreement brings to an end a business relation- ship which began in 1975 and encompassed the Grover test site and the proposed Keota production site. Under the provisions of the termination agreement, Power Resources and Aquarius assume possession of former jointly-held lands in the Grover, Keota, and Buckingham areas in Weld County, Colorado, including the proposed Keota site. The Power Resources-Aquarius joint venture with Powerco as operator remains intact and assumes responsibility for all present and future licensing activities (including currently filed applications) regarding the Keota project. Wyoming Mineral Corporation assumes possession of former jointly-held properties to the north and west, and will continue present responsibil- ities at the Grover test site until the State of Colorado has accepted the site as restored, at which time the Powerco-Aquarius joint venture may accept the facilities at Grover, thus they would become responsible for future activities or any required decommissioning. If not accepted by Powerco-Aquarius, Wyoming Mineral Corporation will decommission the facility and turn it over to Powerco-Aquarius. A GEA-79-304 Page 2 Thank you for your patience and understanding during the recent months of rumor and uncertainty regarding the dissolution of the joint venture. Ms. Frances M. Ryan, Mr. Carleton Rutledge, and I look forward with pleasure to continuing a sound, cordial relationship with you regarding the close out of the Grover test site and with possible other projects Wyoming Mineral Corporation may develop in the future.

GIZLC LEY, COLORADO 80G31 COLORADO March 14, 1978 Mr. Carleton Rutledge, Jr. Manager Licensing Projects Wyoming Mineral Corporation 3900 S. Wadsworth Blvd. Lakewood , Colorado 80255 Dear Mr. Carleton: The Wyoming Mineral operation at Grover, as it is currently operating and with changes proposed to date, would not require a certificate of designation from the Board of County Commissioners pursuant to Section 30-20-101 et seq. , CRS 1973. The described operation does not involve the disposal of solid waste as described in that Act. I would remind you that a certificate of designation could not, in any event, be issued for the Grover site, as Weld County has an exclusive contract for solid waste disposal in the unincorporated areas of the County with a private entity. Any solid waste generated in the site must be eventually disposed of at an approved solid waste or hazardous waste (if applicable) site. Sincerely, P.

As a result of this meeting, my understanding is that Weld County will accept written confirmation on applicant accepta- bility from other agencies as opposed to issuance of a complete set of permits as sufficient enough guide to allow Weld County to proceed with a Special Use Permit for Wyoming Mineral Corporation's Keota Production Facility.

The ponds are constructed of Vona Sandy Loam (SCS Symbol 76 or 77) soil brought on site from Mr. Bud Lingelbach's farm (approximately 1 mile away in the East z of Section 24, TlON, R62W). The surface layer of the Vona Sandy Loam is typically about 10 inches thick. Therefore, design criteria for the removal of surface materials called for stripping to that depth. Data from the Soil Conservation Service indicates that this topsoil is a deep, well-drained soil on 1-3% (76) , and 3-5% (77) slopes. When irrigated, this soil is suitable for all crops adapted to the northern Weld County area, and is apparently as good or better in quality as the Olney Loam (51 and 53) and Halverson Loam (36) over which the ponds were constructed. The outside dimensions of the two storage ponds are 239 feet by 132 feet, and the berms are 4 feet high (see enclosed amended map GEA-78-205) . The slope of the sides is approximately 3:1. It was estimated that about 1788 cubic yards of surface material was obtained for the construction. The ponds are located along the northwest boundary of the property. The ponds are lined with a 30 mil plastic liner approved for uranium operations. The liner is approximately 110 feet square which covers the top of the berm. Upon completion of operations at the site, the remaining solids and the plastic liner from the ponds will be disposed of off-site in compliance with existing state and federal regulations. It is our reclamation plan to distribute the berm materials over the western and southern portions of the site in a grade and contour which approximates the original topography. However, since topsoils may vary within units, the overall quality of the berm materials as a medium for plant growth will be evaluated by standard agrinomic tests prior to grading. We expect that these analyses will confirm that the berm l ff cc, /l nr�t-./ iY;;/,/ �'A10f1n n1 A' GEA-78-367 Page 2 materials are satisfactory for revegetation. If they are marginal, soil amenities (fertilizer, organic matter), as required, will be applied prior to seeding and planting, as described in our approved reclamation plan. In the unlikely event that the materials appear unsuitable, then consideration will be given to returning the berm soils to the excavated area from which they were obtained. If there is any additional data needed for your office, please feel free to contact me. Your attention to this matter is appreciated. Sincerely, Frances M. Ryan Associate Licensing En 'neer cc: T.

These permits now expire July, 1978. This time extension is being requested to conduct additional engineering tests and demonstrations with a non-ammonia alkaline leach solution in a Colorado environment not previously impacted by a leachate injection in order to achieve a more complete understanding of the mining/ restoration involved. In accordance with the above extention request, Wyoming Mineral Corporation would appreciate your extending its present Mined Land Reclamation Permit No. SM-77-159 to encompass said request. The existing approved Reclamation Plan will be initiated upon completion of project about July, 1979. Your cooperation in this matter would be appreciated.

ATTACHMENT 5 Page 2 of 5 Revision 0 THE SOLUTION MINE FACILITY EXTERNAL APPEARANCE The Well Field The well field is an array of wells designed to permit controlled lixiviant contact with the ore body in the host formation beneath the ground (Figure 5-1) . The wells are either injection wells through which the lixiviant is introduced to the ore, or recovery wells from which the uranium-bearing liquor is drawn. The field is installed in a generally regular geometric pattern, although irregularities may occur at the edges of the orebody. The well field is designed and operated to achieve the following: 1. Confine solution flow to the mineralized zone. 2. Extract the maximum amount of uranium from each cell in the well field. 3. Extract the uranium with a minimum flow of solution (i.e. , at the highest recovery solution grade) . Y In defining the economically mineable parts of the ore body such. physical and geochemical characteristics as uranium ore grade, chemical equilibrium, hydrologic permeability, porosity, and leachability are considered. A number of drill holes are cored through the mineralized ATTACHMENT 5 Page 3 of 5 o z Revision 0 O o w 4 w 3 O O & z t W p T--1 W I z J o I I 0 W O O O-- J J O O O O w J O O O O O U E.

The mineable ore body can then be divided into mining units, which are subsequently divided into well fields, which themselves are further divided into production cells. Additional drill holes then may be done to determine the mineable extent of the ore body in greater detail as needed. The mining units having been defined, a well field development plan is designed for a specific mining unit. The initial well fields are positioned on the best and most completely defined portion of the mining unit. The well field is drilled to straddle the ore body along the roll front. Rows of injection wells are drilled across the roll front perpendicular to its strike from the center out until cutoff grade material is reached on either side, thus defining the lateral extent of the mineable ore. The recovery wells can then be drilled and completed. As the well field drilling is completed, the vertical extent of mineable ore is defined and a final estimate of mineable pounds of U308 is made. The vertical underground movement of injected fluids is confined by overlying and underlying clay or shale horizons. Horizontal movement of injected fluids is controlled by well completion techniques, well spacing, *NOTE: Exploration and core drill holes installed by Wyoming Mineral Corporation when no longer needed are plugged with cement and mud to prevent movement of fluids between formations, especially to prevent contamination of other aquifers by leach solution and to ensure containment of the leach solution. ATTACHMENT 5 Page 5 of 5 Revision 0 and the pumping regime. In an injection well, the open-hole or screened interval is positioned relative to the ore; however, in a recovery well, it is positioned relative to the intervals of adjacent injection wells. As the recovered solution from a cell declines to an uneconomic grade, the cell is shut off, and a new cell is brought on line. This process is repeated until the well field is mined-out. The Plant Area The initial Keota process plant facility will consist of a main process building housing modular process units to allow an initial annual output of approximately 150,000 pounds of U308 in a slurry form. This production capacity will be increased to 250,000 pounds per year in the second year and 500,000 pounds per year in the third year. The main process building will cover about 24,000 square feet. It will include a raised section about 40 feet high to accommodate the ion exchange columns. The building will be a standard steel structural framed unit, covered with pre-painted skin of 24-gauge sheet steel. It will have fiberglass insulated walls and ceilings. The floors will be notless than six inches of'reinforced, treated concrete equipped with a central drain and sump system to reclaim all plant liquids used in processing, washing, etc. The structure will be designed for easy expansion to accommodate modifications or process changes during the life of the plant and for easy decommissioning at the end of mining activity.

Implementation of programs in this regard will be through the site radiation protection officer and compliance through mine management. See Figure 6-1 attached herewith which delineates WMC organizational positions of interest. Sources of potential radiation exposure to personnel at the Keota Plant shall be identified and quantified by the implementation of an ongoing radiological monitoring program. This program will be designed to maintain exposures of employees to radiation and to radioactive materials as low as is reasonably achievable. To meet these ends, the radiation protection program will be consistent with the recommendations of NRC Regulatory Guide 8.10, "Operating Philosophy for Maintaining Occupational Radiation Exposures as Low as is Reasonably Achievable" and the Colorado Department of Health Document entitled "Operating Philosophy to Maintain Radiation Exposures as Low as Practicable". The data generated by the plant radiation protection program will be appropriately documented, will be filed at the mine site, and shall be available for inspection to ensure that operations are conducted well within permissible exposure limits. • ATTACHMENT 6 Page 2 of 41 Revision 0 WYOMING MINERAL CORPORATION J.C.

Workers shall either shower or monitor themselves at the end of any shift during which some activity may have caused personnel contamination. An Alpha survey system shall be available at the exit of the change room. Spot surveys shall be performed by the plant radiological officer for alpha contamination on workers leaving the change room. Alpha contamination on skin or clothing in excess of 1000 dpm/100 cpm2 shall require decontamination. Alpha contamination surveys of the lunch room, clean side of the change room and representative office areas shall be performed at least monthly. If surveys reveal that contamination levels exceed the appropriate values of Annex A, U.S. NRC, November 1976, the area shall be decontaminated to appropriate limits. Any such required actions will be appropriately documented. 6.6 INTERNAL AUDIT AND REPORTS The following inspections and audits shall be performed: Quarterly inspections by the plant radiological officer of process and storage areas and a report to the plant manager on ATTACHMENT 6 Page 8 of 41 Revision 0 any items of non-compliance with plant operating procedures, license requirements or safety practices which affect radio- logical safety. • Semi-annual inspections by the corporate RPO and an audit of quarterly inspection reports and all monitoring data shall be conducted. A written report shall be submitted to the plant manager and the manager of Government and Environmental Affairs. This report shall include an evaluation of license compliance programs and provide recommendations to the plant manager regarding any suggested corrective actions required. The report shall also include evaluation of employee exposures, and environmental data to determine (1) if there are any upward trends developing in personnel exposures, (2) , if exposures are being maintained as low as is reasonably achievable and (3) if equipment for exposure control is being properly used and maintained. An annual audit of the plant operations shall be conducted by the Corporate Compliance Review Board in accordance with its Charter. A report of the Board's findings will be submitted to the plant manager. At least annually, all plant operating procedures shall be reviewed by the plant manager and plant radiation protection officer to ensure continued applicability and the adequacy of radiological controls. Actions taken as a result of this audit will be appropriately documented. ATTACHMENT 6 Page 9 of 41 Revision 0 6.7 ADDITIONAL RADIATION PROTECTION PROCEDURES 6.7.1 Bioassay Program At a minimum, quarterly urinalysis for uranium shall be performed for employees permanently assigned to the processing plant. Additional samples will be collected from employees assigned ? 20 hours/week to product packaging operations and maintenance activities as appropriate as determined by the plant Radiation Protection Officer. The routine bioassay program shall be supplemented by additional samples collected from employees for the following: a. If air sampling indicates that an individual's exposure to airborne uranium exceeded 40 MPC hours in any period of seven consecutive days whether the employee was or was not wearing respiratory protection. b. If respiratory protective equipment was found to be defective or contaminated after use. c. Following any unusual clean-up/maintenance activities as appropriate. Bioassay Programs will be consistent with the applicable requirements of NRC Regulatory Guide 8.11 and the final form of NRC Regulatory Guide 8.22. However, it is felt that annual whole body counting will not be necessary unless precipitated by an unusual exposure episode. Section 6.9.7 of this attachment presents example procedures and associate documentation techniques for bioassay programs. ATTACHMENT 6 Page 10 of 41 Revision 0 6.7.2 Respiratory Protection Program It is not anticipated that any plant routine activity will require respiratory use. However, special circumstances, i.e. , unusual maintenance or clean-up activities, may require such protection. Accordingly, a respiratory protection program will be administered consistent with the requirements of NRC regulatory guide 8.15. This program will be admin- istered by the plant Radiation Protection Officer who will be qualified by virtue of successful completion of an approved course on this subject (NSC, NIOSH, etc.) . 6.7.3 Maintenance Activities For unusual maintenance/clean-up activities which may involve the potential for unusual levels of exposure to radioactive materials a Radiation Work Permit Procedure will be used. This procedure may require additional radiological controls for that specific job by the plant Radiation Protection Officer (special personal protective equipment, respirators, breathing zone sampling, bioassay, etc.) . Section 6.9.6 presents an example of this procedure and associated documentation mechanisms. 6.8 ENVIRONMENTAL RADIOLOGICAL MONITORING An environmental radiological monitoring program has been developed in order to provide a periodic check on the potential radiological impact on the environment. This program will consist of the following • procedures. ATTACHMENT 6 • • Page 11 of 41 Revision 0 6.8.1 Quarterly air samples shall be collected at the site boundaries in the prevailing wind direction and analyzed for radon-222 concentrations (minimum two samples/quarter) .

General One of the daughter products in the uranium decay series is Radon 222, an inert gas. Although radon itself is only a minimal health problem (the majority of gas which one inhales is immediately exhaled) ; radon grows into several short half-life particulate daughter products which can pose a health threat to the lung. This procedure presents the details of determining radon daughter concentrations in air. B. Frequency of Sampling As per Texas Department of Health Radioactive Material License 10-2537, this procedure (or radon gas sampling - see Procedure XI-2) must be performed at least monthly at selected process areas including: 1. Calcium removal processes 2. Calcium processing areas - 3. Downwind lips of calcite waste/evaporation ponds 4.

BRUNI PLANT HEALTH PHYSICS MANUAL TITLE Airborne Uranium Grab Sampling NO. XIII APPROVED: EFFECTIVE DATE 8/1/78 PLANT MANAGER PAGE OF 2 RADIATION PROTECTION OFFICER REVISION 0 A. General Grab Air Sampling involves passing a representative sample of air through a filter paper disc via an air pump for purposes of determining the con- centration of uranium in breathing air at that location. Although the procedure is only measuring airborne concentrations at a specific place and at a specific time, the results can often be used to represent average concentration in a general area. A Baird Atomic Sampler, or similar high volume pump will be used for this purpose. Samples will be analyzed as per standard gross alpha analysis procedures using the RD-14 detector. B. Applicability As per TDH Radioactive Material License 10-2537, representative grab air samples shall be collected weekly at work stations in the calcining/ pacakaging area during routine operational periods to determine airborne uranium concentrations. Additionally, special sampling is required during cleanup or maintenance activities in the calcining/packaging area and other process areas as appropriate. Grab sampling may also be required during certain jobs as specified by the radiation work permit procedure or during decontamination activities. C. Assignment of MPC Hours of Exposure to Employees Whenever grab sampling procedures indicate that concentrations in work locations exceed 25% of the applicable value in the TDH Regulations, Appendix 21-A, time weighted exposures of employees who have worked at these locations shall be computed. Whenever calculations reveal that an individual was exposed to 1 MPC hour or more in any one shift, this value shall be assigned to him and logged onto his "Employee Exposure to Airborne Radionuclides" form (attached to Procedure XII) . Whenever special air sampling programs (as required for cleanup, mainten- ance, decontamination incidents, etc.) reveal an employee has been exposed to 1 or more MPC hours, the calculated value shall also be appropriately assigned as above. (See Procedure XII, Breathing Zone Sampling, for calculations of MPC hours of exposure.) • ATTACHMENT 6 • Page 22 of 41 Revision 0 WYOMING MINERAL CORP. BRUNI PLANT HEALTH PHYSICS MANUAL TITLE Airborne Uranium Grab Sampling NO. XIII APPROVED: EFFECTIVE DATE 8/1/78 PLANT MANAGER PAGE 2 OF 2 RADIATION PROTECTION OFFICER REVISION 0 D. Procedure 1. A Baird-Atomic or similar high volume pump shall be used for grab air sampling. 2. The locations selected for sampling should be representative of exposures to employees working in the area. . 3. For special sampling, the sampling period should represent the conditions during the entire period of exposure. This may involve sampling during the entire exposure period. 4. For routine sampling, the sampling period must be sufficient to ensure a minimum of 350 ft3 of air sampled. 5. Filter paper discs shall be analyzed as per standard gross alpha counting procedures using the RD-14 detector. 6. Grab sampling procedures may be supplemented by the use of Breathing Zone Samples for special jobs or non-routine situ- ations. 7.

BRUNI PLANT HEALTH PHYSICS MANUAL TITLE Use of Breathing Zone Samplers ��O XII APPROVED: EFFECTIVE DATE 8/1/78 PLANT MANAGER PAGE 1 OF 2 RADIATION PROTECTION OFFICER REVISION 0 A. General Breathing zone samplers (MSA pumps and accessory kits) are used to determine airborne exposure to uranium while individuals are performing specific jobs. The units consist of a DC powered low volume pump which attaches to the individual's belt, tygon tubing and filter holder which is attached to the individual's lapel or shirt collar. The unit monitors airborne uranium in a man's breathing zone while performing certain tasks involving potential airborne exposure. Pumps must be recharged after 6-8 hrs of use. B. Applicability Breathing zone samplers will be required for all maintenance activities involving possible airborne uranium exposure. Additionally, other specific jobs which require a radiation work permit (see Procedure X) may require breathing zone sampling. C. Procedure 1. Whenever performing calciner equipment maintenance, or as required by the Radiation Work Permit procedure, or as requested by the plant RPO, secure the breathing zone sampler which has been charged and loaded with a filter paper from the plant RPO. 2. Secure pump to belt and filter holder to shirt collar or lapel. Try to consolidate tubing to minimize restriction of motion. 3. Turn pump on (recording the time and flow rate) and continue monitoring until the task is completed and you are no longer in the exposure area. Record the time and flow rate at which the job is completed. 4. Return pump and accessories to the Radiation Protection Officer, who will remove the filter paper for analysis. Be sure to indicate accurately the total time and flow rate. (NOTE: As filters load with dust, the flow rate may drop; therefore an "average" flow rate, initial vs. final must be used.)

Analysis of filter papers will be as per standard gross alpha counting procedures using the RD-14 detector. 6. Record MPC hours of exposure that are being assigned to the employee on the Employee Exposure to Airborne Radionuclides Form which is maintained in personnel files. Be sure to consider protection factors permitted by respirator use if the employee was also wearing respiratory protection during the job. 7. The number of MPC hours assigned is calculated with the formula: MPC hours = Measured air concentration x Total hours of exposure (MPC) (PF) of exposure where, MPC = maximum permissible concentration (for natural uranium; Appendix 21-A, Texas Department of Health Regs) PF = protection factor for respirator use. (If no respiratory protection was used, PF = 1.) The measured air concentration must be in pCi/cc. • 8. Based on the results, bioassay samples (urinalysis) may be required. See Procedure No. XXII. D. Calibration Calibration of breathing zone samples will be performed routinely, but at a minimum of 3-month intervals.

In order to use your air sampler, the unit needs to be calibrated. Enclosed is a graph of flowrate versus flowmeter ball reading for two Eberline samplers No. 0508 and No. 0466 similar to what you will prepare for your pump. The calibration equipment you will make consists of a plexiglass cylinder about 2 feet long and 2 1/2 inches internal diameter. Cap one end of the cylinder with a plexig3.ass disk. From your chemistry laboratory borrow a 1 liter beaker. Fill the calibration cylinder with about 6 inches of water and permanently mark the outside cylinder wall indicating the water level. Using the beaker, add 1 liter of water and again mark the final water level on the cylinder. Empty the water and install a small nozzle through the capped end of the cylinder. Connect the nozzle to the inlet of your MSA pump using tygon tubing or equivalent. Prepare a dish of soapy water using ordinary dishwashing detergent. Turn on your pump and dip the open cylinder end into the soapy water. A soap bubble should begin traveling up the cylinder. By measuring the time required for the soap bubble to traverse the distance between the two 1 liter marks you can estimate the time required by the pump to displace 1 liter of air. The inverse of this time measurement is the flowrate in liters/minute. Repeat this procedure for several flowmeter ball readings and plot the results on linear log paper. Your pump now has a calibration curve to convert ball reading to pump flowrate in liters per minute.

BRUNI PLANT HEALTH PHYSICS MANUAL TITLE Bioassay Sampling rip XXII APPROVED: EFFECTIVEDAlE 8/1/78 PLANT MANAGER PAGE 1 OF 3 RADIATION PROTECTION OFFICER REVISION A. General Definitive measurement of the intake of radioactive materials into the body can only be made via Bioassay techniques. The standard techniques used include whole body counting, i.e. , measurement of gamma rays coming out of the whole body or some specific portion of the body (lung, e.g. ) , fecal analysis, sputum analysis and urinalysis. Urinalysis is usually the first and easiest technique employed to determine possible intake of uranium via inhalation or ingestion. As many employees at the Plant will be requested to donate urine samples for analysis at one time or another, the "Instructions for Bioassay Sample Required" form (attached) must be signed off by all employees before assignment into potentially contaminated areas. B. Requirements for Bioassay - General Bioassay (urine) samples are usually required for one of two technical reasons; investigation or diagnosis. Investigative analysis involves sampling at some defined frequency to insure that air sampling results are representative of actual intake and that procedural controls are effective. Diagnostic sampling is used following a known or suspected intake to evaluate how much radioactive material has actually entered the body. As the procedures for collection of these two types of samples are slightly different, they will be treated separately below. C. Investigative Samples - Routine Requirements 1. Need a. As per TDH Radioactive Materials license 10-2537, all employees assigned to the Calcining/Packaging area shall donate a sample for analysis at least quarterly.

Procedure for routine investigative samples: (a) At the end of a week' s shift, after clean-up and before leaving the site for your days off, pick up a sample bottle from the site RPO. (b) Deposit your sample at home, the evening or morning just before returning to work. (c) Samples should be deposited 48 hours after your last work assignment but within 96 hours and before re-entering a potentially contaminated area. (d) Make sure your sample bottles are properly labelled with your full name, social security number, and date of deposit. (e) It is very important to insure that the bottles have not been contaminated. Never touch your sampling bottle with potentially contaminated hands or bring your sample bottle into a potentially contaminated area. D. Diagnostic Samples - Requirements Urine sampling may be required under special circumstances. Under any of the conditions outlined below, the sample must be deposited at home the evening or morning before returning to work. Samples are required if: 1. An employee has used respiratory protection if the lack of such protection would have involved an exposure to uranium of > 40 MPC hours or the respirator was surveyed and found to be contaminated.

During personnel contamination surveys, the mouth or nose area has been found to be contaminated. 3. Any episode has occurred in which there is reason to believe possible ingestion or inhalation of radioactive material. E. Diagnostic Samples - Procedure 1. If exposure to airborne uranium is suspected, a sample should he deposited at home immediately following the shift during which the incident occurred. Additionally, a sample should be collected 2-4 days following the incident. 2. If injection is suspected, E-1 above also applies. Additionally, fecal sampling should begin immediately. All fecal excretions should be collected and analyzed for at least 48 hours after known significant intakes. F. Baseline and termination samples Prior to assignment in a potentially contaminated area, all new employees will have a sample collected and analyzed to determine baseline uranium concentrations in urine. At termination, employees must donate a final urine sample. Both baseline anal termination samples should he deposited at home applying procedures (b) through (e) of C-2 above (this may be NA for terminating employees) . C. Action Level Criteria and Associated Required Actions - Urinalysis Should the results of urinalysis sampling meet either nC the following criteria, a formal documented evaluation shall he made. The components of this evaluation are discussed below. ATTACH?{EN'T 6 • Page 36 of 41 Revision 0 WYOMING MINERAL CORP. BRUNI PLANT HEALTH PHYSICS I1ANUAL TITLE Bioassay Sampling NO.

The product will be placed in DOT specification drums that will be blocked and braced before leaving the plant by truck. (Alternative means of transport involving possible use of tank-type trucks for wet products are under investigation.) An Emergency Action Plan and an Emergency Response Plan exist that would initiate immediate action and/or response to an on-the-road incident with technical expertise and necessary survey/decontamination equipment. The Wyoming Mineral Corporation agrees fully with the determinations and required actions as indicated in the document "Regulatory and Other Responsibilities as Related to Transportation Accidents" (NUREG-0179) , published by the Office of Standards Development, U.S. NRC, June 1977. Data on the transportation of radioactive materials indicates that the probability of a truck accident occurring in transport is very small: about one for each million vehicle miles*. Should a trans- portation accident occur resulting in a release of product, the Emergency Response/Action Plans should minimize potential impacts. As the product is primarily an alpha emitter, impact to humans as the result of direct radiation exposure will be minimal. *U.S. Department of the Interior, Draft Environmental Statement, Sherwood Uranium Product, Spokane Indian Reservation, Vol. 1, 1976.

Pull vehicle off the road onto shoulder or, if on rail, onto an isolated section of track. 2. Contact one of the following WMC personnel to assist and advise clean-up/decontamination procedures: Steven Brown Radiation Protection Officer 303/988-8530, Ext. 207 or Bart Conroy Manager of Process Development 303/988-8530, Ext. 210 or Site Radiation Protection Officer (to be designated) 3. Limit spread of contamination by marking off spillage area, re-routing traffic around spill if possible, limiting pedestrian access to/through area, etc. 4. If so advised by individual in Item 2 above, while wearing gloves, right any drums, containers, etc. , and place back on vehicle, if by doing so additional leakage/spillage will not occur. 5. After consulting per Item 2 (above) , if advised, notify police, firemen, etc. that a radioactive material spillage has occurred and they are needed to assist in area control. They should wear protective clothing (gloves, boots, etc.) when entering ATTACHMENT 6 • Page 41 of 41 Revision 0 area. Inform responding local authorities to bring shovels, high pressure water supply, and containment vessels (if necessary) to affect clean-up. Inform them of the extent of the incident and what measures are being taken to protect health and property. Local officials should not become involved in clean-up activities until health physics personnel have arrived. • 6. If a vehicular accident has resulted in fire, causing the potential for airborne radioactivity, protective respiratory equipment must be worn while combatting the fire. 7. When Health Physics assistance has arrived, have as much spillage as possible and affected soil, etc. vacuumed up and placed into original containers (if not badly ruptured and can be reused) or similar containment vessels. (If radioactive material involved is dry, cover with plastic sheets or tarp in such a manner as to reduce further spreading to unaffected areas before recovering.) 8. After as much contamination as possible has been recovered, hose down the affected area with large volumes of water (also a survey of the affected area has been performed) . Recover wash waters in appropriate vessels, if possible. 9. The affected area must be adequately surveyed after all clean- up activities are completed and prior to releasing the area for public access. Emergency Response Plan In the event of a transportation incident, the driver is instructed as per the emergency action plan to contact one of the three WMC individuals. 1. Upon receiving notification and details of the incident, the WMC individual would, based on the degree and requirements of the emergency, organize a response team by contacting additional WMC people for assistance. 2. The appropriate regulatory agency would be notified of the incident, details available at the time, and actions that will be taken. 3. The emergency response vehicle (stationed at the WMC Boulder Lab) would be outfitted with decontamination supplies and survey equipment. 4. If replacement drums are required, they would be obtained from the WMC local supplier in Denver. Drums are available on a 24-hour call basis. 5. The outfitted vehicle, supplies, drums, and personnel would be en route to the scene of the incident within four hours of the initial phone call. mr- NI _ �■ ATTACHMENT 7 Page 1 of 11 Revision 0 ATTACHMENT 7 (This attachment supplies information required by Item 15 of Form•0R-RH-12) CONTROL OF WASTES AND EFFLUENTS The system for control of effluents released from the proposed solution mining facility is designed to minimize any adverse environ- mental consequence to the extent reasonably achievable. Utilization of the "best practical control technology currently available" for incorp- oration into the control system designs was practiced. Relationship of Waste Generation to Waste Control Systems: The relationship of the major process components in the solution mining operation and the associated waste control system is shown schematically in Figure 7-1. Waste generation is related to a variety of factors such as: (1) The characteristics of the ore body, (2) The type of lixiviant used, and (3) The length of time, or rate, of mining. The effluent control system designed for the lixiviant to be utilized in the Keota ore body will be a central facility. All wastes will be impounded or disposed of by removal from the plant site. • ' ATTACHMENT 7 9 Page 2 of 11 y p a Revision 0 wcn 4a CC cn F- I- COD W W rn 0 0 I_ a 03 1 Z . - 0 w Z H CC ix Z 0 3W � CL o U di Z U O Z z a A A .

ATTACHMENT 7 ' Page 3 of 11 Revision 0 Airborne Effluent Control: The solution mining facility will have very low levels of airborne releases both from the processing facility as well as from the mining area (well field) . Fugitive dust from the operations are limited to the disturbed areas for the processing plant, well field, and temporary roads con- structed to support the solution mining operations. Since no overburden or ore removal operations are practiced, significant dusting will be experienced only during the initial construction of the mine facility, thereafter on temporary roads,- and during well field drilling operations. It is not anticipated that dust control, other than good engineering practice during construction, will be necessary. Chemical airborne emissions are associated with low level releases due to evaporation from storage ponds and general plant ventilation. If the primary lixiviant process alternative, ammonium bicarbonate, is used the principal emissions will be ammonia, ammonium chloride, and carbon dioxide. To reduce, wherever possible, the release of volatile chemicals from plant process operations, all process components are covered wherever practical and plant ventilation rates are maintained at levels that assure plant operation safety in compliance with all applicable regulations. All ponds utilized in the process to store solid materials will be covered with a liquid seal to minimize the atmospheric dispersion of these solids. ATTACHMENT 7 Page 4 of 11 Revision 0 Currently, no uranium product drying facility is planned for the Keota project. As such no particulate emissions of uranium are antici- pated. • Liquid Waste Control: The liquid wastes generated in the plant, from the well field, and during groundwater restoration operations will be impounded in lined ponds. Separate ponds for the high total dissolved solids (TDS) process bleeds, the low TDS well field overproduction, the low TDS restoration waters and the slurry calcite by-product will be utilized. Typical pond schematic is shown in Figure 7-2. Construction of typical ponds will be rectangular, earthen-bermed, and lined with a 30 mil nylon-reinforced plastic liner to prevent seepage. All topsoil will be stockpiled, forming part of the earth berm surrounding the ponds. The floor of the ponds will be compacted clayey subsoil. Each pond will be equipped with a leak detection system. In addition to waste storage, the ponds will be designed for natural evaporation to reduce the volume of the contained waste. Ponds will be constructed and operated in such a manner that should a leak occur, the contents of the leaking pond may be safely evacuated into an adjacent pond or ponds while liner repairs are effected. Typical waste compositions for the various waste streams to be evaporated in the pond system are given in Table 7-1. At the end of • ATTACHMENT 7 Page 5 of 11 Revision 0 A a: ,yv 2\ i-i ,,,;,-,,N,Cr.

ATTACHMENT 7 Page 7 of 11 Revision 0 mining operations, all waste water in ponds will be evaporated to dryness and the residual solids stabilized as described under solid waste control. Solid Effluent Control: Two types of solid wastes are produced as a result of the solution mining operation. These are calcite solids generated for calcium control in the process and the solids produced as the result of evaporation in waste water ponds. Both of these solids are contained in lined ponds during the operation. During the mining operation the calcium control circuit could produce up to 250 tons/year of solid calcite by-product. This calcite will be temporarily retained in a lined pond prior to final disposition at a licensed tailings facility. At such time, any residual uranium which may be present in the calcite solids will be recovered if economi- - cal. Such alternatives as on-site burial were evaluated. It was felt that the small volume of calcite solids with the anticipated level of 500 to 1,500 pCi of radium-226 would be most suitably disposed of at an existing licensed tailings Tacility, if available. The residual salts contained in waste water ponds are an additional source of solid wastes. Since it is anticipated that these wastes contain no significant concentration of radionuclides or trace elements, these solids will be stabilized by burial on-site. (Estimated concentrations • ATTACHMENT 7 Page 8 of 11 Revision 0 of trace species that may be residual in these evaporated solids are shown in Table 7-2.) Should the solids contain significant amounts of U308, they may be re-dissolved and recycled through the plant. A cost-benefit analysis was performed on waste disposal alternatives to arrive at the optimum pond stabilization plan. The reduction of any radon emmanation from reclaimed ponds to twice background was used as the basis of this analysis. The results of this study indicated that minimal pond covers were needed in order to completely stabilize the residues and reduce radon emanation nearly to background. Figure 7. 3 shows the model that was used to perform the calculations. As is seen, the residual waste thickness determined what, if any, clayey soil cover is required to reduce radon emanations. For the expected levels of trace elements and radium-226, only a return of the original topsoil to the pond as cover for the wastes will be required to reduce radon to less than twice background. Figure 7-4 shows a worst-case calculation of total thickness required for a level of 80 pCi/gm. Appropriate cover thicknesses will be used depending on residual radium-226 levels and waste thicknesses to reduce radon emanation to below twice background levels.

Although additional Grover testing under the present permit will give feasibility information, this new method must be tested in virgin ground within the permitted area not previously contaminated with ammonia to achieve a more complete understanding of both the mining and restoration process for ISL-2. o The Corporation finds the outlook very promising for a highly effective non-ammonia process that can be designed into the proposed Keota Production Facility from the outset. It is particularly pertinent and advantageous to prove the process for Keota (a Colorado facility) with a test done nearby under similar geological conditions within Colorado.

INTRODUCTION - Wyoming Mineral Corporation is involved in a test of insitu uranium mining at the Grover, Colorado test site. As part of the process, - groundwater, affected by the leach solution used in the mining process, is to be restored to acceptable water standards prior to site reclamation. WMC has been involved in a slug test restoration activity, in a feasibility test of the proposed restoration process in wellfield #1 and is currently involved in plant construction of a facility that will completely restore the Grover test site. B. INITIAL SLUG TEST RESTORATION RESULTS The results of the slug test have been previously submitted to the Colorado Department of Health and are summarized below. 1. Operation • Injected % 4000 gal. NH4 HCO3 lixiviant. • Recovered ti 20,000 gal. of groundwater (5 pore values) . • Processed groundwater using reverse osmosis. 2. Results • TDS (Conductivity) reduced to near baseline. • NH4+ reduced from ti 1000 ppm 4. 20 ppm (average) • Trace Elements--No significant increases except for U308 and vanadium (U308 = 5 ppm V = 1.7 ppm) • Radionuclides: Ra-226 and Th-230 were at baseline. _ 3. Stability Testing = • NH4 levels stable at rtl.. 18 ppm for 9 months. - • Conductivity also stable % 450-500 pmhos. 4. RO Process Information - — Up to 90% water recovery possible. _- • Permeate < 200 pmhos for recycle. Typical results from the initial RO clean-water recycle operations are shown in Table 2. These results, when compared to the initial results indicate some clean-up of the formation. The rate at which this clean-up is occurring is, however, slow due to the small size of the restoration plant. To date, less than one pore volume of water has been treated. A comparison with the results from the slug test restoration indicates that about five pore volumes would be required to reduce the concentrations to acceptable levels.

Slug Restoration Test Conclusions • Groundwater sweeping is effective. • RO recycle can conserve water. • Aquifer appears stable after 9 months. C. WELLFIELD 1 RESTORATION TEST A restoration plan for a portion of the original test field (wellfield - #1) was formulated and implemented in late November, 1977. The test consisted of: 1. Well Field Evaluation 2. Plant Construction 3. Restoration Operations C-1 Wellfield #1 Evaluation In order to determine the extent of the leach solution boundary outside of wellfield #1, an exploratory drilling program was conducted as shown on the attached map (Figure 1) . Two wells, PG-1A and PG-2R were completed and sampled for water quality. These results are shown in Table 1. As can be seen, some amount of lixiviant had impacted this area; however, the ammonia values were quite low. A computer simulation of alternate wellfield configurations was performed and an appropriate wellfield pattern chosen. This pattern is shown in Figure 2. Wells G-6, PG-1, PG-2, and G-10 were used as injection wells and G-8 was used for recovery. C-2 Test Operations A flowsheet utilizing a reverse osmosis process was developed for implementation on a portion of wellfield #1. This flowsheet is shown in Figure 3. The process used in this flowsheet is a clean-water recycle process in which water is drawn from the wellfield, treated for contaminant removal and then re-injected with the formation to conserve water. The test plant consisted of a reverse osmosis water treatment plant that was capable of 6 gpm. The plant was constructed in November, 1977 and operations began in December, 1977. Extreme cold weather prohibited operation for much of the time and only a total of 10 operating dates were logged in mid-December and January. It has been decided to move the restoration test plants inside the Grover plant building and to expand its capacity to enable operation on the entire- wellfield #1. A 30 gpm restoration plant is under construction as described below. D. GROVER RESTORATION: Total Site It has been decided that partial restoration of Grover wellfield #1 as a demonstration of restoration feasibility should be expanded to include the entire Grover test site operations. As such, two restoration activities are currently under construction to enable complete restoration of the Grover site by July 21 , 1978. D-1 Wellfield #1 Restoration Test An outline of the planned activities and anticipated schedules for restoration of wellfield #1 is given below. The process of clean-water recycle, as described above, will be used as the restoration process. 1. Wellfield Evaluation (Anticipate January 15 - February 28) • Exploratory drilling to define the extent of leachate impact around the test area. • Caliper logging of existing test wells. • Computer simulation to determine most desirable flow pattern. 2. Plant Construction (February 15 - March 10) • Expansion of restoration plant capacity to 30 gpm. Location of restoration equipment in main process building. • Construction of two 100,000 gallon temporary storage ponds to hold restoration process water. 3. Plant Operation • Clean water recycle method. • Anticipated completion: June 15, 1978. D-2 Wellfield #2 Restoration/Mining Test A new process, ISL-2, will be used to test mining and restoration in the previously ammonium bicarbonate leached test field #2. The restoration plans for_ this test field are as follows: 1. Concurrent Mining/Restoration (March 1 - May 15, 1978) • Ammonia removal • Further mining characterization of formation 2. Post-Test Restoration (May 15, 1978 - July 31, 1978) • Clean water recycle to remove residual traces of — " ISL-2 lixiviant. . �, 1\ Figure 1: GROVER RESTORATION 0GM-5 - AG-6 PG-- ifs PG�I Well Field #1 5_, gl G-8 • PG-g I, G 7 P®2 - G-10 - PG-3 G-9 p G-12 G-II G-I6 G-18 G-20 Well Field #2 ®G-2 ®G- G-17 t, G-2I 6-19 PM-2 GM-2 GM-2 . • { Y 4 y LU 4 ' IF S " . {.• 4 I (%J 1 2: t • X-- J S t L7 r- ' • It L l- 4 (, • i t • W -- CL -I.

Start-up is expected for February 15, 1978 due to the rapid construction completion of the facility. It was previously, scheduled for commencement on March 1, 1978. Wyoming Mineral Corporation considers the below information proprietary; it is submitted in confidence and is to be used solely for the purpose for which it _s furnished. It is not to be reproduced, transmitted, disclosed, or used otherwise in whole or in part without the written authorization of Wyoming Mineral Corporation. The ISL-2 method of defining the mineralization of the ore body involves two principal reagents, oxygen (02)- and calcium bicarbonate Ca(HCO3)2 , at a pH of 6.0 to 6.5. The steady state leach chemistry may be found in Table 1. The carbonate and calcium may vary ± 0.3 gpl while the uranium levels may vary ± 0.5 gpl. Essentially, the process involves a two-stage process: (1) uranium precipitation; and (2) CO2, 02 gas saturation. Figure 1 shows a general outline of the process flow streams involved with the two-stage process. Recovered solution is pumped from the well field to a CO2 removal system where the solution is depressurized and CO2 gas evolves off into the atmosphere. The solution is then pumped to the precipitator thickner where hydrated lime is added in order to precipitate the uranium, and as a result of the increased calcium and pH, calcium carbonate and magnesium hydroxide react to produce precipitated solids. The resulting precipitate contains approximately 96% calcite, 2% UO2, and 2% Mg (OH)2. The overflow from- the precipitator is then pumped to the gas saturator where CO2 is added to neutralize the Ca(OH)2 and bring the bicarbonate level back up to original leach conditions. Finally, 02 gas is added to the flow streams to saturation before being injected back to the aquifer. - WYOMING MINERAI; RPOION PROPRIETARY -GEA-78-219 Page 2 Due to the .favorable equilibrium of a high pH, the lixiviant is able to extract NH3 from the previously leached field solution (ISL-1) . The overflow from the precipitator will be pumped to a spray tank where the high pH solution will be sprayed into the tank evolving NH3 gas. _ A fan will then vent the ammonia.

A modification or clarification of Development Standard ##21 is also being requested to allow for concurrent licensing of a Keota Production Facility with this Grover Extension Request. Specifically, the Corporation requests that the Keota full production application (yet to be submitted) be. considered for authorization by January 1979 while, in fact, the ISL-2 test will not be totally restored until July 1979. The Corporation originally understood Standard ##21 to apply to the Grover area and, in fact, had not identified the Keota site at the time of Special Use Permit 303: 76:8 consideration. In accordance with this request, enclosed please find the following amended material to the above-mentioned permit: • Summary of SUP application requirements indicating needed changes. • Amended Special Use Permit Application. • Amended Development Standard #21. Due to encouraging results of on-going tests using the ISL-2 process in other field demonstrations in Wyoming, Wyoming Mineral Corporation finds it necessary to conduct these additional tests in an area within the present permit boundary not impacted by a previous leachate injection in order to achieve a more complete understanding of the minim;/restoration process for ISL-2 or similar non-ammonia alkaline leach solutions in the Colorado environment. The requested time extension would allow Wyoming Mineral to perfect this mining and restoration technique on a Colorado test site prior to employing it on the Colorado Keota full-production site. GEA-78-311 Page 2 Wyoming Mineral Corporation emphasizes that this extension merely allows further testing of the same magnitude as the ISL-1 tests and does not imply a production facility. If there is any additional data that is needed by your office, please contact me. Your attention to this matter is appreciated. Sincerely, R\ �rance's M. Ryan Associate Licensing Engineer Enclosures FMR:kes SUMMARY OF NEEDED CHANGES 1 (a) Enclosed (b) See Exhibit A (c) See Exhibit A (d) Refer to Special Use Permit No. 303:76:8 same (e) The proposed test will not require additional resources or will not impact the environment beyond the impact of ISL-1 systems as described in earlier application submittals. The primary difference is in the ionic balance within the mine zone upon completion of mining and prior to restoration. The ISL-2 process does not use an ammonia-based lixiviant system and, therefore, no ammonia is present during or after the mining is complete. A comparison of major ionic species remaining after mining of the ISL-1 and ISL-2 is shown in Table 1. The test will be designed and run to determine the effectiveness of restoration techniques to stabilize the ground to desired restoration levels. The groundwater impact of mining the ISL-2 method will be lower because no ammonia will be used in the process and because the general TDS of the mining solutions are lower. The number of shifts to be worked and maximum number of employees may be found in the initial Special Use Permit No. 303: 76:8. (f) Refer to Special Use Permit No. 303:76:8 same (g) Refer to Special Use Permit No. 303: 76:8 same (h) Refer to Special Use Permit No. 303: 76:8 same (i) See Exhibit B TABLE 1 COMPARISON OF EXPECTED POST-MINING GROUNDWATER CONCENTRATIONS* ISL-1 ISL-2 NH4 0.2 - 1.0 0 Cam 0.02 - 0.2 0.1 - 0.5 Na+ 0.2 - 0.4 0.3 - 0.5 Mg++ 0.02 - 0.04 0.02 - 0.04 HCO3 1.0 - 3. 0 1.0 - 3.0 CO2 (as H2CO3) 0 0.5 - 2.0 C1 0.5 - 1.5 0.01 - 0.1 SO4 0.2 - 0.5 0.2 - 0.5 U308 0 - 0.05 0 - 0.05 pH 7.0 - 8.5 6.0 - 7.5 * All concentrations given in grams/liter L&S-78-097 ' Wyoming Mineral Exp/or and Mining (900 S Wadsworth Blvd Corporation Divisioi; Lakewood Cob 80235 Phone 303 988-8530 A Subsidiary of Westinghouse Electric Corporation January 16, 1978 Mr. Tom Honn y Weld County Planning Commission , , ,L l'JU 915 10th Street '\ Greeley, Colorado 80631 E , Subject: ISL-2 for the Grover Test Facility Dear Mr. Honn: As per our discussion and understanding on 1/9/78, I have outlined below a brief process description for the ISL-2 method scheduled to commence at the Grover Test Facility on 3/1/78. Also, for your information, Ken Webb and Bill Dunn, CDH-Water Quality, verbally approved this method on 1/12/78. Upon receipt of written approval I will forward it to your office. Thank you for your cooperation and verbal approval on this subject.' During the course of testing operations at the Grover Test Facility, Wyoming Mineral Corporation has developed two methods to mine and restore for uranium. The present tests at Grover have produced sufficient data to indicate the effectiveness of the ISL-1 method (ammonium bicarbonate lixiviant) . Beginning 3/1/78, WMC plans to employ an ISL-2 method which involves a calcium bicarbonate lixiviant. It is a method that will accelerate the rate of removal of ammonia from the groundwater, thus initiating_restoration_of.the aquifer while simultaneously continuing to test the formation for mining characteristics (i.e. porosity, permeability, process chemistry) . The ISL-2 method is scheduled to last 2-3 months at which time WMC will proceed with its second stage of restoration to remove Lire remaining major and trace ions. The environmental impact of such a method would be identical to that of chemical restoration of the aquifer. The bi- carbonate levels are the same, therefore no additional impact. Since calcium is a natural consituent there will be no foreign species that are introduced. The calcium concentration will be expected to vary from 100-800 ppm during the test. This will naturally be reduced during the second stage of restoration. I look forward to our meeting on 1/23/78 and if there are any further ques- tions or comments on this subject, please feel free to call. Sincerely, . .--)Th ('JlkQ ,; 01.--: \ ` -p-r-- Frances M.

Weld County Centennial Center 915 10th Street b1Greeley, Colorado 80631 tillitiMM Dear Mr. Cunliffe: � r _ ' - We have reviewed the special use permit application amendments (SUP-303:76:8) .,; ,� from Wyoming Mineral Corporation (WMC) to consider the desirability of the .=:-.• `-.: requested changes in development standards #2 and #21. In addition to our - prior comments (May 28, 1976) on the original special 'use permit application, we offer the following suggestions. The' substitution of calcium bicarbonate for ammonium bicarbonate (develop- ment standard #2) appears to present no additional detrimental effects from the solution mining of uranium at the Grover test site. In fact, 'N' it offers a method of extraction compatible with chemical restoration of the aquifer. It is not made clear by the information available, however, -» where the new injection wells will be located, nor in what degree any additional surface disruption may occur within the permit boundary. With respect to amended development standard #21, we note that the intent of the original application was to determine the feasibility of full production. Production is implied in WMC's clarification that the amended development standard #21 will allow for concurrent licensing of a Keota facility in January of 1979 (as described in a letter from WMC to .c Mr. Thomas Honn dated March 2, 1978) . Therefore, restoration of ground- k� water flows and surface alterations apparently is not intended until the ' termination of the Keota production facility. This matter should be ' clarified in negotiating permits and licenses for the future production facility. Si cerely you s, 1 . �i T ,` t f^,,/ John L.

Temporary Use Permit for Wyoming Mineral Corporation:7 _ Offer by Wyoming Mineral to Post a Bond for Reclamation Purposes CONCLUSION: It is doubtful that Weld County has the authority to issue a Temporary Use Permit for the purpose Wyoming Mineral intends. If the Board of County Commissioners should decide to issue such a permit, it would create an undesirable precedent by granting the company special treat- ment not authorized by the Weld County Zoning Resolution. DISCUSSION: Section 6.1(1) of the Weld County Zoning Resolution provides: In any zoning district where a building, structure or use is enumerated, any other building, structure or use which is similar to those enumerated and is no more obnoxious or detrimental to the area in which it is located, shall be permitted. (Emphasis added) This section is designed to allow flexibility in the application of the Zoning Resolution, so that a use will not be denied simply because the drafters of the Resolution failed to anticipate it. However, the flexibility provided in Section 6.1(1) is not unlimited. Uses which are not listed in the Zoning Resolution must be compatible with and similar to other uses specifically authorized in a zone. Section 3.3Y incorporates Section 6.1(1) in providing that uses similar to the listed uses allowed temporary use permits will be reviewed and, if approved, issued temporary use permits. Therefore, the contemplated use must not only be similar to listed uses, it must also be "no more ' obnoxious or detrimental to the area" than listed uses. Section 3 .3.C of the Weld County Zoning Resolution provides for the issuance of a temporary permit by the Planning Department for certain uses of land. The uses enumerated in Section 3.3.C.2 as temporary uses are: a. Temporary construction yard or building for construction materials and equipment, mobile home for office use, and concrete batch plants, incidental and necessary for construction in agricultural zone districts. . . b. Temporary office incidental and necessary for the sale of new construction by the permittee. . . c. Mobile homes may be used for temporary living quarters incidental and necessary for the construction of a residence on the property. . . Memorandum ^� �' '4 June 76 • page 2 d. Temporary group assemblages. . . With the exception of the last, all of the uses listed in this section are related to construction of some permanent improvement on the land. They are not uses which are part of the use which will finally be made of the land. They do not involve any disturbances of the land's subsurface. Wyoming Mineral Corporation has applied for a Temporary Use Permit under Section 3.3.C for the purpose of moving equipment onto the land prior to conducting production operations. The company wishes to set up their equipment and to drill test holes so that when, and if, a Special Use Permit is granted, they can commence production immediately. When Wyoming Mineral 's application for a Temporary Use Permit was brought before the Planning Commission on June 15, I suggested that the Commission recommend denial for two reasons: 1. It is my opinion that the County does not have the authority to issue a Temporary Use Permit for the purpose contemplated by Wyoming Mineral, because the use is not similar to those enumerated by the Zoning Resolution; nor is it, to my thinking, "no more obnoxious or detrimental to the area" than the listed uses. 2. Even iE the Board of County Commissioners should feel that the activities Wyoming Mineral wishes to conduct do fall within the scope of the Temporary Use Permit, the Board should consider the precedent they are creating by the issuance of such a permit before a Special Use Permit for the mining operation itself is granted. The Special Use Permit is an exception to existing zoning regulations. The granting of a Temporary Use Permit as well, could be construed as granting an additional exception to what is already the exception procedure. The Planning Commission subsequently did recommend denial of the Temporary Use .Permit. After the Planning Commission meeting, I was contacted by Mr. llaradon Beatty, of the Denver law firm of Holland and Hart, who is representing Wyoming Mineral. We discussed the problems I had pointed out to the Planning Commission in the issuance of a Temporary Use Permit. Mr. Beatty offered to draft an agreement which would require Wyoming Mineral to restore any disturbed land in the event the Special Use Permit for production is denied. Copies of a letter from Mr. Beatty and the proposed agreement are attached. As you can see, Wyoming Mineral is offering to post a substantial bond as a guarantee of its performance of obligations under this contract. I find nothing wrong with the proposed agreement per se. That is, it does offer the County considerable security that Wyoming Mineral will not enter onto the land involved, conduct test operations, Memor;tudum • 24 June 76 `� A page 3 i and then either disappear without reclamation or refuse to leave in the event the Special lie Permit is denied. However, it is still my opinion that the Board would be creating an undesirable precedent in accepting such an offer. The Board would be instituting a special exception for which no standards or procedures exist in the current Weld County Zoning Resolution. It would, in effect, be sanctioning a use which has not yet been reviewed under the Special Use Permit process. KM:ep 1 Iqmir doe cotop RICHARD D. LAMM K -r 1• 7 C.J.

Wadsworth Blvd. Lakewood, CO 80235 Re: Monitoring Procedure for Restoration, Grover Site Dear Fran: We request Wyoming Mineral Corporation to initiate the following procedures in monitoring the restoration program at the Grover test site: 1 . Upon completion of the groundwater sweeping program to 50 ppm anunonin or lass (approx. 6 weeks to completion) , we want all wells to be capped and protected. The cap is to be of a temporary nature so the wells will be accessible for further sampling if necessary. We suggest a locking device of some kind be installed on the wells to prevent any contamination during the shut- in period. 2. After completion of the groundwater sweeping program and prior to inactivation of all wells we request the following wells be sampled PG-2, PG-5, PG-6, PG-7, PG-11 , and G-19. The samples should be analyzed for the following parameters : ammonia, conductance, pH, dissolved solids, uranium, vanadium, alpha and beta radiation. 3. After a shut- in or stabilization period of 45 days we request the wells and parameters listed above again be sampled and analyzed. We request we be notified at least one week in advance of this sampling period so that representatives of the Division can be present. The wells are not to be pumped prior t0 sampling except under the supervision of the Division representative. 4. The wells will then be shut- in for another 45 days and the above procedure in (3) be repeated unless changed by the Division. . .r i Frances H. Ryan September 19, 1978 Page 2 5. Additional moni Loring well (s) will be drilled at a location lo be decided upon at the expiration of the 90 day monitoring program outlined above and after review and evaluation of the sample results . 6. A long term monitoring program will be prescribed by the Division in consultation with WMC upon completion and evaluation of the 90 day program outlined above, however, in the event of a failure by the Division to prescribe a long term monitoring program, the procedure outlined in item (3) will be performed by WMC on a quarterly basis until the Division releases WMC from further monitoring obligations or unless the Commission gives WMC premission to plug all holes of the project. ' A--7. In addition to the monitoring program outlined above the Division requests all of WMC sample analysis previously conducted on wells PG-3R, PG-4R, PG-6R, and PG-7R.

This facility is anticipated to produce 500,000 pounds of "yellowcake" per year when at full operating capacity. The plant is expected to start in late hil 1979. 1 I l SIThese status reports are intended to keep land and mineral owners and other interested l parties informed of project progress. This first report contains highlights of major I activities since the Grover test facility near Grover, Colorado was started in 1977 }c and, as a matter of background, provides a brief look at the primary partners involved tic in the overall project. Each issue will also address different organizational units li within WMC. This issue speaks specifically of the WMC Government and Environmental II / Affairs Department. Subsequent issues will address other involved Departments. A REVIEW OF RECENT EVENTS . . . �y I Grover Test Facility: ii . Test operations at the Grover facility started in May of 1977. The Grover ,i test facility is on a seven acre area approximately 3) miles southwest C, of Grover, Colorado. II I il . Wyoming Mineral Corporation held an Open House presentation at the . Denver Hilton for Colorado legislators and government officials on November 3, 1977, and at the Winterset Inn in Greeley on November 4, it 1977 for our Weld County neighbors. The presentation consisted of a slide presentation on solution mining and specifically, our activities I{ at our test facility near Grover were discussed. '� I j A Solution Mining Workshop was held in December where the Corporation l 1 disseminated basic information on the in-situ mining technology to technical and professional personnel from the Colorado, Wyoming,Montana and Federal regulatory and environmental agencies. WMC also i, I participated in the 81st National Western Mining Conference in Denver I. in early February, 1978 with an exhibit on solution mining. These I! provided opportunities to discuss WMC's activities and to achieve 1, I' Ibetter public understanding of the project. !

WMC also has actively participated in the Forest iN 3 Service's RARE II Program, advocating a well-rounded wilderness i; Iprogram encompassing the multiple use concept. �� 1! Wyoming Mineral Corporation contributed $500 to the Denver Audubon i)i Society in April, 1978 to help start their Grover Wildlife Center ly Project. The old railroad station at Grover is to be converted to jy a laboratory and study center for visiting scientists doing research on the Pawnee Grasslands. Dedication ceremonies for this Nature ti± Center will be held August 18 in Grover. ii The Weld County Board of Commissioners, on May 24, 1978, granted an l( extension to July 1, 1979 of the Special Use Permit for the Grover site to allow additional testing. Extensions of State permits ,,s ,11 were also granted by applicable State agencies. 4\ fllllll h New Production Facility �I Wyoming Mineral Corporation is preparing an application for a Colorado Department of Health Subsurface Disposal Permit for the full production facility. Various geohydrological data are being gathered in the Keota j d area to determine baseline groundwater quality, aquifer characterization, I, and ore body definition. Concurrently, an application for a Source ,,, Material License is being prepared, also for submittal to the Department j of Health. An Environmental Report is required as part of the Source Material application. Biological, archaeological, and socio-economic ;y surveys have been initiated in the area in support of the Environmental Report effort. II Numerous meetings have been conducted with the State ti and County regulatory agencies to discuss data needed by them and to 'II outline WMC's approach in applying for a full production license. h i An application will be submitted to the Weld County Planning Commission II jy and the Weld County Board of Commissioners for a Special Use Permit. ii Applications also will be submitted to the State Engineer's Office, the li Mined Land Reclamation Board, and several other state agencies in the fl coming months in compliance with Colorado's laws. 1, c il Government Interfaces: S { if I In response to concerns expressed by local residents over the exploratory r drilling program, Wyoming Mineral Corporation escorted a member of the ii 4ti Colorado Agricultural Council around the Grover test site and the field ;; studies near Keota to demonstrate Powerco's sound drilling program. i i fl `I II �l 'II , ll ii �� r_s=------_,--- RECENT EVENTS, CONTINUED . . . ??

Other News: l At the Colorado School of Mines Engineers' Days, April 7 and 8, 1978, IWMC's exhibit of in-situ solution mining of uranium won second prize for quality of presentation. I Wyoming Mineral Corporation and Power Resources Corporation both continue to be concerned about any unplugged exploration wells left ,1 by earlier exploration companies. Nearly two years ago, a reward ;( of $5.00 was offered for each unplugged well reported near the WMC/Powerco operations. Just two wells have been reported and were plugged promptly. The offer still stands. If you have one to report, contact , the WNC Project Manager, Bill Kauffman (Phone - 221-5700 in Fort Collins) . 1 ti, 1; i ti� the Pawnee Project in the beginning...

Grover Test Site-Aerial View THE GOVERNMENT AND ENVIRONMENTAL AFFAIRS DEPARTMENT As operating partner in the Pawnee Uranium Project, Wyoming Mineral Corporation is involved with the acquisition of the appropriate permits and licenses for the project. This responsibility is in the hands of the Government and Environmental Affairs Department,originally called the Licensing Department.As their charter expanded to include radiation and industrial safety,public acceptance programs,environmental and restoration standard studies,regulatory and legislative analyses and permit compliance auditing, it became necessary to create three sub-groups for smooth and efficient handling of these activities. As a result of this expansion, State and Federal Licensing Groups and an Environmental Projects Group were formed under the Government and Environmental Affairs Department. In addition to obtaining the necessary licenses and permits, it is the responsibility of the Department to ensure that the conditions of the permit are carried out and complied with until such time as a project obtains"commerical status",at which time the operating mine manager assumes this responsibility. The Government and Environmental Affairs Department is also responsible for carrying out radiation and field safety activities, specific environmental testing and monitoring projects and scientific research studies in support of license and permit applications. The expertise within the Government and Environmental Affairs Department includes the special fields of geology, hydrology, biology, health physics, safety, economics and regulatory law. Administrative and graphics functions assist greatly in the permit and license application process.The following picture guide introduces this department.The next status report will highlight another WMC Department.
