IN"fRODUCTION 1.
National Environmental Goals Prior to the issuance of a license authorizing uranium milling activities, the Nuclear Regulatory Commission (NRC) is required to assess the potential environmental effects of the proposed activities in order to ensure that issuance of the licen3e will be consistent with the national environmental goals.
In order to obtain information essential for this assessment, the Commission requires each applicant for a license to submit a report on the potential environmental impact of the proposed uranium mill and related activities.
The national environmental goals are expressed by the National Environmental Policy Act (NEPA) of 1969 (Public Law 91-190, 83 Stat. 852),
as follows:
a
..it is the continuing' responsibility of the Federal ravernment to use all practicable means, consistent with other essential considerations o f national policy, to improve and coordinate Federal plans, functions, programs, and resources to the end that the Nation may--
"(1) fulfill the responsibilities of each generation as trustee of the environment for succeeding generations;
"(2) assure f or all Americans safe, healthf ul, productive, and esthetically and culturally pleasing surroundings; 4,c 1, 0, 0 tv
"(3) attain the widest range of' beneficial uses of the environment without degradation, risk to health or safety, or other undesirable and unintended consequences;
"(4) preserve important historic, cultural, and natural aspects of our national heritage, and maintain, wherever possible, an environment which supports diversity and variety of individual choice;
"(5) achieve a balance between population and resource use which will permit high standards of living and a wide sharing of life's amenities; and
"(6) enhance the quality of renewable resources and approach the maximum attainable recycling of depletable resources."
In addition to NEPA, the Atomic Energy Act of 1954, and the Energy Reorganization Act of 1974, numerous other pieces of legislation and implementing regulations, both Federal and State, may affect the siting and operation of uranium mills.
Some of these, such as the Endangered Species Act of 1973, require that the NRC make primary determination of acceptability, while compliance with others, such as the Federal Water Pollution Control Act, must be reported to the NRC.
No attempt will be made in this guide to discuss any of these in det. ail.
The applicant should make an independent determination of those statutes and regulations that may affect the proposed mill. Early consul-tation with the staff is encouraged to determine relevancy in specific instances.

Applicant's Environmental Reports 10 CFR Part 51, " Licensing and Regulatory Policy and Procedures for Environmental Protection," 651.40, " Environmental Reports," requires that each applicant for a license authorizing uranium milling submit 15 copies of a separate document entitled "The Applicant's Environmental Report" with the license application.
The applicant must retain an additional 85 copies of the environmental report for distribution to Federal, State, and local officials in accordance with written instruc-tions issued by the NRC's Director of the Office of Nuclear Material Sa fety and Saf eguards. The applicant's environmental reports are important documents of public record. Therefore, the applicant is urged to give full atte ntion to their completeness.
The environmental report must discuss the following environmental cons ide ra t i ons :
The environmental impact of the proposed action, a.
b.
Any adverse environmental effects that cannot be avoided should the proposal be implemented, c.
Alternatives to the proposed action, d.
The relationship between local short-term uses of man'n erviron-ment and the maintenance and enhancement of long-term productivity, and e.
Any irreversible and itretrievable commitments of resources that would be involved in the proposed action should it be implemented.
O vi 142 19?
The discussion of alternatives to the proposed action in the environ-mental report must be sufficiently complete to aid the Commission in developing and exploring, pursuant to Section 102(2)(D) of the National Environmental Policy Act, appropriate alternatives.
.in any proposal which involves unresolved conflicts concerning alternative uses of avail-able resources."
The environmental report must also include a benefit-cost analysis that considers and balances the environmental effects of the facility end the alternatives available for reducing or avoiding adverse environmentai effects, as well as the environmental, economic, technical, and other benefits of the facility. The benefit-cost analysis must, to the fullest extent practicable, quantify the various factor; considered.
To the extent that such factors cannot be quantified, they must be discussed in qealitative terms.
The environmental report should contain sufficient data to aid the Commission in its development of ar. independent benefit-cost analysis covering the f actors specified.
The environmental report must further include a discussion of the stat us of compliance of the f acility with applicable environmental quality standards and requirements that have been imposed by Federal, State, and regional agencies having responsibility for environmental protection.
In addition, the environmental impact of the facility should be fully dis-cussed with respect to matters covered by such standards and requirements irrespective of whether a certification from the appropriate authority has been obtained (including, but not limited to, any certification obtained pursuant to Section 401 and any discharge permit obtained pursu-ant to Sect ion 402 of the Federal Water Pollut ion Control Act, as amended).
While compliance with NRC standards and criteria pertaining to radiological effects will be necessary to meet the licensing requirements of the Atomic Energy Act, the benefit-cost analysis for the purposes of the National Environmental Policy Act must consider the radiological effects together with a broad range of ot her environn. ental ef fects of the f acility.

Preparation o f Envi rotunen_t al Reports Purpose of T_his Guide a.
The Commission's regulatiov in 10 ad Part 51 orovide only general information concerning the content of an applicant's environmental report.
This guide has been prepared to provide specific and detailed guidance for the preparation of environmental reports for uranium mills.
The guide identifies information needed by the NRC staff in its assessment of the potential environmental effects of the proposed uranium mill and di rectly associated mir.ing activities and establishes a format acceptible to the staff for its presentation.
Conformance with this s t.a nd a rd format, however, is not required.
Use of the format of this the completeness of the information provided, will guide will help ensure assist the NRC staff and others in locating the information, and will aid in shorteping the time needed for the review process.
b.
Scope of This Guide In order to cover a wide variety of anticipated situations, the
., cope of this guide is comprehensive In some instances, requests for specific information may not be applicable to a particular mill or site.
If any topics are not relevant to the particular mill under consideration, the applicant should identify them.
If any topics in this guide relate to information not asailable at the time the report is prepared, the applicant should indicate when the information will be available.
c.
Presentation of Information The applicant should strive for clear, concise presentation of the information provided in the environmental report.
Each subject viii I42 194
should be treated in sufficient depth and with sufficient documentationn to permit the Commi n i on to evaluate the extent of the environmental impact independently.
Tables, line drawings, and pho'.ographs should be used wherever they contribute to the clarity and brevity of the report.
The number o f signi ficant figures stated in numerical data should reflect the accuracy of the data.
Descriptive and narrative passages should be brief and concise.
In cases where test results are needed to support conclusions, test data procedures, techniques, and equipment. used to perform tests should be included.
Pertinent published information relating to the site, the mill, and its surroundings should be referenced.
Where published information or assumptions are essential to evaluate specific environmental effects of the proposed activities, they should be included in sumury or verbatim f orm in the environmental report or as an appendix to the report.
Some of the information t.
ae included in the environmental report may have already been prepared by the applicant during preparation of the license application for the proposed mill.
In such cases, this i n f o rma tion (whether in the form of text, tablea. or figures) should be incorporated in the environmental report where appropriate in order to provide a complete document.
The site for the mill mr.y also be the site of the mine The applicant, in preparing the environmental report relating to cuch a mill, should consider the cumulative or synergistic effects of directly asso-ciated mining activities.
- Documentation as used in this guide means presentation of information, supportic:g data, and statements and includes (1) references to published information, (2) citations f rom the applicant's experience, and (3) reference to unpublished information developed by the applicant or the applicant's consultants. Statements not supported by documentation are acceptable provided the applicant identifies them either as inf ormation f or which documentation is not available or as expressions of belief or judgment.

ENVIRONMENTAL EFFECTS OF SITE PREPARATION, MILL CONSTRUCTION, AND MINE OPEN _ING The construction of a uranium mill and the openings of related mines will inevitably affect the environment; some of the effects will be adverse and some may be beneficial.
Effects are considered adverse if environmental change or stress causes a valuable or otherwise important biotic population or natural resource to be less safe, less healthy, less abundant, less productive, less esthetically or culturally pleasing; if the change or stress reduces the diversity and variety of individual choice, the standard of living, or the extent of sharing of life's amenities; or if the change or stress tends to lower the quality of renewable resources or to impair the recycling of depletable resources.
In the applicant's discussion of adverse environmental effects, it should be made clear which of these are considered unavoidable and subject to later amelioration and which are regarded as unavoidable and irreversible.
Those effects that represent an irretrievable commitment of resources should receive detailed consideration in Section 4.2.
(In the context of this discussion, " irretrievable commitment of resources" alludes to natural resources and means a permanent impairment of these, e.g.,
loss of wildlife habitat; destruction of nesting, breeding, or nursing areas; interference with migratory routes; loss of valuable or esthetically treasured natural areas; and expenditure of directly utilized resources.)
4.1 Site Preparation and Construction The applicant should organize the discussion in terms of the ef fects of site prepacation (including mine opening) and mill construction on 142 214 4-1
both land use and water use. The applicant should consider causequences to both human and wildlife populations and indicate which are ur. avoidable, irreversible, etc., according to the categorization set forth earlier in this chapter.
In the land-use discussion, describe how construction activities may disturb the existing terrain and wildlife habitats.
Consider the effects of such activities as creating building material supply areas; build.ag temporary or permanent roads, bridges, or service lines; disposing of trash; excavating; and land filling. Provide information bearing on such questions as how much land will be torn up, for how long, will there be dust or smoke problems, what explosives will be used, where and how of ten.
Indicate proximity of human populations and identify undesirable impacts on their environment arising from noise, disruption of stock grazing patterns, inconvenience due to the movement of men, material, machines, including activities associated with any provision of housing, transportation, and educational facilities for workers and their f amilies.
Describe any expected change:, in accessibility of historical ar.d archeo-logical sites in the region.
Discuss measures designed to mitigate or reverse undesirable ef fects, such as erosion control, dust stabilization, landscape restoration, control of truck traffic, and re s to ra t i o n of a f fected habitats.
The discussion should also include any etfects of site preparation and onstruction activities whose consequences may be beneticial to the re t;i o n.
The discussion of water use should describe the impact of site preparation and construction activities on area water sources.
Such activities would include mine dewatering, diversion of streams, placement of fill material in water, etc.
The applicant should describe the ef fects of these act ivities on t ish and wildlif e resources, water quality, 4-2 A ')

water supply, esthetics, etc., as applicable. Describe measures to miti-gate undesirable ef fects such as pollution control and other procedures for habitat improvement.
4.2 Resources Committed Discuss any irreversible and irretrievable commitments of resources (loss of land, destruction of biota, etc.) that are expected should site preparation and mine opening and mill construction proceed. Such losses should be evaluated in terms of their relative and long-term net impacts, as well as their absolute impacts.

ENVIRONMENTAL EFFECTS OF MILL AND MINE OPERATION This chapter describes the interaction of the mill and mine (discussed in Chapter 3) and the environment (discussed in Chapter 2).
To the extent possible, material presented in Chapters 2 and 3 does not need to be repeated. Measures planned to reduce any undesirable effects of the tot al project on the environment should be described in detail.
In the discussion of environmental ef f ects, as in Chapter 4, ef f ects that are considered unavoidable but either inherently temporary or subject to later amelioration should be clearly distinguished from those regarded as unavoidable and irreversible. Those effects that represent an irret rievable commitment of resources should receive detailed considera-tion in Section 5.6.
The ispacts of operation of the proposed activity should be, to the fullent extent practicable, quantified and systematically presented.
In the discussion of each impact, the applicant should make clear whether the supporting evidence is based on theoretical, laboratory, onsite, or field st udies undertaken on this or on previous occasions. The source of eacb impact (the plant subsystem, waste effluent) and the population or res urce affected should be made clear in each case.
The impacts should be distinguished in terms of their effects on surface water bodies, ground water, air, land, land use, acolegical systems, and important plants and ani.nals.
Finally, the applicant should discuss the relationship hetween local s ho r t -t e rm us<s of man's environment and the maintenance and enhancement of long-term productivity.
As used in this guide, "short term" reters to the operating 1ife of the proposed faciIity and "long 142 217 s-i
term" refers to time periods extending beyond this life. The applicant should assess the action for cumulative and projected long-term ef fects from the point of view that each generation is trustee of the environment for each succeeding generation.
5.1 Radiological Impact on Biota Other Than 'ian In this section the applicant should consider the impact on biota other than man attributable to the release of radioactive materials from the facility. The biota to be considered are those species of local flora and local and migratory f auna defined as "impc-tant" in Section ~ 9 Since the region may contain many important species, the applicar.
should concentrate any efforts on those important species whose terrestrial t ad aquatic habitat ; provide the highest potential for radiation exposure.
5.1.1 Exposure Pathways The various possible pathways for radiation exposure of the important local flora and local and migratory fauna should be identified and described in textual and flow-chart format. The pathways should include the important routes of radionuclide translocation (including food chains leadirg to important species) to organisms or sites.
5.1.2 dadioactivity in the Environment In Sections 3.4 and 3.7, the radionuclide and chemical concentrati ens in the liquid and gaseous effluents discharged from the site are listed.
In this section, the applicant should consider how these effluents are quantitatively distributed in the environment. Specifically, estimates should be provided for the radionuclide concentration (a) in any water sources, (b) on land areas, and (c) on vegetation (on a per unit area basis) in the environs.
5-2 142 218
If there are other components of the physical environment that may becoca contaminated and thus result in the exposure of living organisms to radiation, they should be identified and their radioactivity burden estimated.
In addition, information concerning any cumulative buildup of radionuclides in the environment should be presented and discussed.
A summary of data, assumptions, and models used in determining radioactivity concentrations and burdens should be provided.
From considerations of the exposure pathways and the distribution of radioactivity released into the environs, the applicant should estimate the maximum radionuclide concentrations that may be present in important local flora and local and migratory fauna. Values of bioaccumulation factors used in preparing the estimates should be based on site-specific data if available; o the rwi s e, values from the literature may be used.
The applicant should tabulate and reference the values of bioaccumulation factors used in the calculations.
5.2 Radiological Impact on Man in this section the applicant should consider the radiological effects of oparationa and transportation of radioactive materials on man.
Estimates of the radiological impact on man via various exposure pathways should be provided.
5.2.1 Exposure Fathways The various possible pathways for radiation exposure of man should be identified and described in textual and flow chart format.

5.2.2 I.iquid Effluents E..timate the expected annual average concentrations of radioactive nuclides (listed in Sections 3.4 and 3.7) in receiving water at locations where water is consumed or otherwise used by human beings or where it is inhabited by biota of significance to human food chains.
Specify the dilution factors used in preparing the estimates and the locations where the dilution factors are applicable Consideration should be given to the absence of mixing and dilution because of f act ors such as channeling.
Determine the expected radionuclide concentrations in aquatic and terrestrial organisms significant to human food chains. Use the bioaccumu-lation f actors given in Section 5.1.2 or supply others as necessary.
Using the above information and any other necessary supporting data, calculate the total annual body and significant organ doses (millirems) to individuals in the population (discussed in Section 2.3) from all receiving-water-related exposure pathways, i.e.,
all sources of internal and external exposure.
Provide, as an appendix, details of the models and assumptions used in these calculations.
5.2.3 Airborne Effluents From release rates of airborne radioactivity and meteorological data (Sections 3.4, 3.7, and 2.8), estimate total annual body and signif-icant organ doses (mi l l i rems ) to individuals exposed at the point of maximum ground-level contentrations off site, individuals exposed at the site boundary in the direction of the prevailing wind, individuals exposed at the site boundary nearest to the sources of emission, and individuals exposed at the nearest residence in the direction of prevailing wind. Assume annual average meteorological conditions. Identif y locations of points of release (e.g., stack, roof vent) used in calculations.

5.2.5 Summary of Annual Radiation Doses The applicant should provide estimates of the maximum annual doses (millirems) to an individual at the site boundary and the nearest residence
. hat could be received via all pathways.
The applicant should also present a table that summarizes the estimated radiation dose to the regional population (within 80-km) from mill-and mine-relited sources using values calculated in previous sections.
The tabula; ion should include (a) the total annual doses (man-rems) to the population (discussed in Section 2.3) f rem all receiving-water-related pathways and (b) the total annual doses (man-rems) to the population attributable to airborne ef fluents.
5.3 Effects of Chemical Discharges In this section, the specific concentrations of nonradioactive wastes in effluents at the points of discharge should be compared with natural ambient concentrations without the discharge and also compared with applicable standards.
The projected effects of the effluents for 5-5 142 221
both acute and chronic exposure of the biota (including any long-term buildup in soils and sediments and in the tnota) shoulit be iilent i fied and discussed.
Dilution and mixing of disch<irges into the receiving environs should be discussed in de t a i 1, a nd es t in.a t e:, of concentrations at various d i s t. int es from the point of discharge should be provided.
The effects on terreatrial and aquatic environments from chemical wastes that contaminate ground water should be included.

5.5 Other Effects The applicant should discuss any effects of operation that do not clearly fall under any single topic of Sections 5.1 through 5.4.
These may include changes in land and water use at the pr3 ject site, interac-tion of the f acility with other existing or projected neighboring f acilities, effect of ground-water withdrawal on ground-water resources in the vicinity of the mine and mill, effects of construction and operation of roads, transmission corridors, railroads, ete, effects of changes in surface water availah lity on biotic populations, and disposal of solid and liquid wastes ot n r than t ruc e al ready discussed.
5.6 I<esources committed Any ir:eversible and irretrievabic commitments of resources due to mine and mill operation should be discussed. This discussion should include both direct commitments such as depletion of aranium resources and irreversible environmentel losses such as destruction of wildlife habitat.
\\L 9_g
In this discussion, the applicant should consider lost resources f rom the viewpoints of both relative impacts and long-term net effects.
As an example of relative impact assessment, the loss of a few animals of a given species could represent quite dif ferent degrees of significance, depending on the total population in the immediate region. Such a loss in the case of a small local population, however, could be less serious if the same species were abundant in neighboring regions.
Similarly, the loss of a given area of highly desirable land should be evaluated in terms of the total amount of such land in the environs. These relative assessments should accordingly include statements expressed in percentage terns in which the amount of expected resource loss is related to the total resource in the immediate region and in which the total in the immediate region is related to that in surrounding regions. The latter should be specified in terms of areas and distances f rom the site 9

EFFLUENT AND ENVIRONMENTAL MEASUREMENTS AND M0hlTORING PROGRAMS The purpose of this chapter is to describe in detail the means by wnich the applicant collected the baseline data presented in other chapters and to describe the applicant's plans and programs for monitor-ing the impacts of the proposed activities on the environment.
Section 6.1 is addressed to the measurement of preexisting character-istics of the site and the surrounding region. This program will estab-lish a reference framework for assessing subsequent environmental effects attributable to the proposed activity and for use as baseline reference data at the time of site decommissioning.
The applicant's attention is directed to two considerations pertinent to Secticn 6.1.
First, the term " preexisting" refers to the characteristics of the site prior to any mining-related activities. A gisen characteristic 9
or parameter may or may not require assessment prior to site disturbance and mill construction, depending on whether that particular characteristic may be altered at these stages.
Second, in most instances this guide indicates the specific environmental ef fects to be evaluated; consequently, the parameters to be measured will be apparent.
In some cases, it may be necessary to establish a monitoring program based on the applicant's own identification of potential or possible
!ects and to provide the underlying rationale for such a program.
At t
y, the applicant
~
shoeld caref ully review the plans for measurement o. preexisting conditions to ensure that these ple include all factors that must be subsequently monitored as discussed in Section 6.2.

7. ENVIROF 7TAL EFFECTS OF ACCIDENTS The applicant should discuss the environmental effects of possible accidents that may occur at the mill and during transportation of mate-rials to and f rom the mill, whether or not those acciderts may produce an impact on the site or its environs. Analyses should be based on relevant experience and statistics f rom operation of similar milling and transportation aperations. The statistical validity of the data should be discussed as well as the rationale for applying the data to the applicant's proposed operation. Accidents due to both man-caused and natural phenomena should be addressed. 7.1 Mill Accidents Involving Radioactivity The applicant should provide accident analyses for a spectrum of accidents that might occur ranging in severity from trivial (essentially no release of radicactivity to the environment) to very large releases. Each class within the spect rum should be characterized by an occurrence rate or probability and its potential consequences, if any. Examples of accidents resulting in large releases would be a tornado striking the mill er the failure of a waste retention system resulting from an act of nature or misoperation. Examples of accidents resulting in small releases would be a fire or explosion in a solvent extraction circuit or failure of the air cleaning system serving the yellowcake area during operation. An example of a trivial accident would be the malfunction of mill F.cocess equipment or the rupture of a vessel containing mill solutions. 7.2 Transportation Accidents The potential environmental effects from transportation accidents involving radioactive and other hazardous materials should be evaluated. 7-1 A3 '.) ^{ ^'

Adequate docun entat ion should be present ed to pros ide assurance that all sa f ety requi rt ment s will he met prior t o transportation of hazardous materials (e.g., sp illage of ha za rdo u., chemicals, ores, fuels, yellow cake, sulf uric acid). 7.3 Other Accidents In addition to accidents that can release radioactivity to the environs, there may be accidents that, although radioactive materials are not invo!ved, do have consequences that affect the environment. Such accidents as (hemical explosions or tires, steam boiler failures, and leakage or rupture of vessels containing toxic mater als can have .significant environmental impacts 'Inese possible accidents ind asso-ciated et f ect s should be ident i fied and evaluated.

8. ECONOMIC AND SOCIAL EFFECTS OF MILL CONSTRUCTION AND OPERATION The purpose of this chapter is to provide guidance on the information needed to assess the economic and social ef fects of the proposed facility. There are, of course, limitations on the extent to which all the social and economic benefits and costs of a uranium milling project can be evaluated. The wide variety of benefits and costs are not only diffi-cult to assess, but many are not amenable to quantification or even to estimation in commensurable units. Some primary benefits such as the quantity of uranium recovered are, to a degree, measurable as are the capital costs and operating and maintenance costs of the proposed facility. On the other hand, numerous environmental costs ani their economic and social consequences are not readi'y quantified. 8.1 Benefits The primary benefits of the proposed nuclear facility are those inherent in the value of the uranium to be recovered and the kilowatt-hours of electricity it represents. "he re are other social and economic benefits that affect various political jurisdictions or interests to a greater or lesser degree. Some of these reflect transfer payments or other values that may partially, if not fully, compensate for certain services as well as external or environmental costs, and this fact should be reflected in the designation of the benefit. The following lists some examples: Tax revenues to be received by local, State, and Federal governments. Temporary and permanent new jobs created and payroll (value-added concept). 8-1 142 234
Incremental increase in regional product. Enhancement of recreational values. Environmental enhancement in support of the propagation or protection of wildlife and the improvement of wildlife habitats. Creation and improvement of local roads, waterways, or other t ransporta-tion facilities. Increased knowledge of the environment as a consequence of ecological research and environmental monitoring activities associated with plant operation and technological improvements from the applicant's research program. The applicant should discuss significant benefits that may be realized from the construction and operation of the proposed mii. Where the benefits can be expressed in monetary terms, they slm .d be discounted to present worth. In each instance where a particular benefit is discussed, the applicant should indicate, to the extent practical, who is likely to be affected and for how long. In the case of esthetic impacts that are difficult to quantify, the applicant should provide pictorial drawings of structures or environmental modifications vi.ble to the public (refer to Section 3.2). 8.2 Costs The economic and social costs re. s ul t in g from the proposed nuclear f acility and its milling project are likewise complex and need to be appraised. are (1) the capital costs tI land acqui-The primary internal costs sition and improvement, (2) the capital costs of facility construction, 8-2 142 235
(3) other operating and maintenance costs, including license fees and taxes, (4) plant decommissioning, tailings stabilization, and site reclamation costs, and (5) research and development costs associated with potential future improvements of the mill and its operation and maintenance. As in the case of benefits, the applicant should discount these costs to present worth. There are also external costs. Their effects on the interests of people need to be examined. The applicant should supply, as applicable, an evaluation plus supporting data and rationale regarding such external social and economic costs. For each cost, the applicant should describe the probable number and location of the population group adversely affected, the estimated economic and social impact, and any special measures to be taken to alleviate the impact. Temporary external costs include shortages of housing; inflationary rentals or priceo; congestion of local streets and highways; noise and temporary esthetic disturbances; overloading of water supply and sewage treatment facilities; crowding of local schools, hospitals, or other public facilities; overtaxing of community services; and disruption of people's 1ives or the local community caused by acquisition of land for the proposed site. Long-term external costs include impairment of recreational values (e.g., reduced availability of desired species of wildlife and sport animals, restrictions on access to land or water areas preferred for recreational use); deterioration of esthetic and scenic values; restric-tions on access to areas of scenic, historic, or cultural interest; degradation of areas having historic, culturat, natural, or archeological value; removal of land from present or contemplated alternative uses; reduction of regional products because of displacement of persons from the land proposed for the site; lost income f rom recreation or tourism that may be impaired by environmental disturbances; lost income attributable 1A7 ') 8-3 (_ ) )
to environmental degradation; decrease in real estate values in areas adjacent to the proposed facility; increased costs to local governments fc r the services required by the permanently employed workers and their families. In discussing the costs, the applicant should indicate to the extent practical who is likely to be af fected and for how long. O 142 237 9 8-4
9. DECOT1ISSIONING AND RECLAMATION The applicant should describe in depth its plans for mill decommis-sioning and site reclamation. Detailed discussions should be provided for the following: a. Plans for reclaiming and restoring lands disturbed by mining and milling activities. b. A technical and financial feasibility assessment on methods and costs of mill decommissioning and site (including tailings area) reclamation. c. Financial arrangements to be made (such as bonding arrangements, etc.) to ensure that adequate funds will be available for mill decommissioning, site reclamation, and restoration when opera-tions are concluded. In th' discussion of rcclamation of tail. ags disposal areas, consider-ation shouid be given to the following post-reclamation performance objectives developed by the NRC staf f: a. Reduce d i. ce c t gamma radiation from the impoundment area to essentially background. b. Reduce the radon emanation rate from the impoundment area to about twice the emanation rate in the surrounding environs. c. Eliminate the need for an ongoing monitoring and maintenance program following successful reclamation. d. Provide surety arrangements to ensure that sufficient funds are available to complete the full reclamation plan. 142 238 9-1
9 10. ALTERNATIVES TO THE PROPOSED ACTION In this chapter of the environmental report, the applicant's choice particular site and the location of project of a particular mill at a structures on the site must be supported through a comparative evaluation of available alternatives. To the extent possible, the applicant shoold discuss all alternative parameters. The NRC will consider all available alternatives that may reduce or avoid adverse environment..1, social, and economic effects expected to result from construction and operation of the proposed milling and mining project. The NRC will not specify in advance which a l t.e rna t ive s should be selected by the applicant for consideration; rather, the applicant should make this selection and also make clear the basis and rationale for the choices in regard to number, availability, suitability, and factors limiting the range of alternatives that might avoid some or all of the environmental effects previously identified. Particular attention should be placed on the relationship 9 between tailings management alternatives and mill site and process alternatives. In the discussion of tailings management alternatives, considera-tion should be given to the following siting, design, and operation performance objectives developed by the staff in addition to the post-reclamation performance objectives listed in Chapter 9: a. Locate the tailings isolation area remote from people in order to reduce population exposures to the maximum extent reasonably achievable. b. Locate the tailings isolation area so that disruption and dispersion by natural forces is eliminated or reduced to the maximum extent reasonably achievable. 10-1 142 239
c. Design the isolation area so that seepage of toxic materials into the ground-water system would be eliminated or reduced to the maximum extent reasonably achievable. d. Eliminate the blowing of tailings to unrestricted areas during normal operating conditions and prior to. inal reclamation. O 10-2 kkb
11. BENEFIT-COST ANALYSIS In this chapter the applicant's benefit-cost statement should be presented. The presentation should be made in the form of a narrative with accompanying tables and charts. It should make clear what the applicant considers to be the important benefits and costs of the pro-posed f acility and why, in the judgment of the applicant, the former outweigh the latter. The applicant will have to develop criteria for assessing and com-paring benefits and costs where these are expressed in nonmonetary or qualitative terms. The rationales for the selection among site-mill alternatives, as well as among subsystem alternatives, should be pre-sented. In any case, '.he applicant should carefully describe any aggre-gation of effects and discuss in detail the tradeoffs that were made in order to justify the proposed operation. If any of the benefits or costs are deleted from the applicant's enalysis, the rationale for doing so should be explained. The applicant should key all the terms used in the benefit-cost analysis to the relevant sections of the environmental report. 11-1 l42 24i
12. ENVIRONMENTAL APPROVALS AND CONSULTATIONS List all licenses, permits, and other approvals of construction and operations required by Federal, State, local, and regional authorities for the protection of the environment.' List those Federal and State approvals that have already been received and indicate the status of matters regarding approvals yet to be obtained. For general background, submit similar information regarding approvals, licenses, and contacts with local authorities. Discuss the status of efforts to obtain a water quality certifica-tien under Section 401 and discharge permits under Section 402 of the Federal Water Pollution Control Act, as amended. If not already obtained, indicate when certification is expected. If certification is not required, explain. In view of the effects of the plant on the economic development of the region in which it is located, the applicant should also note the State, local, and regicnal planning authorities contacted or consulted. Office of Management and Budget Circular A-95** identifies the State, metropolitan, and regional clearinghouse that should be contacted, as appropriate. Cite meetings held with environmental and other citizen groups with reference given to specific instances of the applicant's compliance with citizen group recommendations. This list should be updated bimonthly until final action is taken by the NRC. Inquiries concerning this circular may be addressed to the Of fice of Management and Budget, Washington, D.C. 20503. ,) k k d-12-1
