110. Introduction. The rules given under R645-302-200 through R645-302-300 establish the minimum requirements for approval to conduct coal mining and reclamation operations under designated special categories and areas of mining. All provisions of R645-301 apply to the designated special categories and areas of mining, unless otherwise specifically provided under R645-302.
120. Objective. The objective of R645-302 is to ensure that special categories and areas of mining are approved only after the Division receives information that shows the coal mining and reclamation operations will be conducted according to the applicable requirements of the Act, R645-301 and any other applicable portions of the State Program.
130. Applicability. Special categories and areas of mining that occur within an approved permit area will be evaluated and approved by the Division within the context of the attendant permit or permit application. Special categories and areas of mining that occur external to an approved permit area will require a discrete permit application for review by the Division. Special categories and areas of mining include all those types and areas of mining described in R645-302-200 through R645-302-320.
The rules in R645-302-200 present the requirements for information to be included in the permit application to conduct coal mining and reclamation operations for designated special categories of mining and present procedures to process said permit applications.
210. Experimental Practices Mining.
211. Experimental practices provide a variance from environmental protection performance standards of the Act, of R645-301, and the State Program for experimental or research purposes, or to allow an alternative postmining land use, and may be undertaken if they are approved by the Division and the Office and if they are incorporated in a permit or permit change issued in accordance with the requirements of R645-200, R645-300, R645-301, R645-302-100 through R645-302-280, R645-302-310, R645-302-320, or R645-303.
212. An application for an experimental practice will contain descriptions, maps, plans, and data which show:
212.100. The nature of the experimental practice, including a description of the performance standards for which variances are requested, the duration of the experimental practice, and any special monitoring which will be conducted;
212.200. How use of the experimental practice encourages advances in mining and reclamation technology or allows a postmining land use for industrial, commercial, residential, or public use (including recreation facilities) on an experimental basis;
212.300. That the experimental practice:
212.310. Is potentially more, or at least as, environmentally protective, during and after coal mining and reclamation operations, as would otherwise be required by standards promulgated under R645-301 and R645-302; and
212.320. Will not reduce the protection afforded public health and safety below that provided by the requirements of R645-301 and R645-302; and
212.400. That the applicant will conduct monitoring of the effects of the experimental practice. The monitoring program will ensure the collection, analysis, and reporting of reliable data that are sufficient to enable the Division and the Office to:
212.410. Evaluate the effectiveness of the experimental practice; and
212.420. Identify, at the earliest possible time, potential risk to the environment and public health and safety which may be caused by the experimental practice during and after coal mining and reclamation operations.
213. Applications for experimental practices will comply with the public notice requirements of R645-300-120.
214. No application for an experimental practice under R645-302-210 will be approved until the Division first finds in writing and the Office then concurs that:
214.100. The experimental practice encourages advances in coal mining and reclamation technology or allows a postmining land use for industrial, commercial, residential, or public use (including recreational facilities) on an experimental basis;
214.200. The experimental practice is potentially more, or at least as, environmentally protective, during and after coal mining and reclamation operations, as would otherwise be required by standards promulgated under R645-301 and R645-302;
214.300. The coal mining and reclamation operations approved for a particular land use or other purpose are not larger or more numerous than necessary to determine the effectiveness and economic feasibility of the experimental practice; and
214.400. The experimental practice does not reduce the protection afforded public health and safety below that provided by standards promulgated under R645-301 and R645-302.
215. Experimental practices granting variances from the special environmental protection performance standards of Sections 515 and 516 of the Federal Act applicable to prime farmlands will be approved only after consultation with the NRCS.
216. Each person undertaking an experimental practice will conduct the periodic monitoring, recording and reporting program set forth in the application, and will satisfy such additional requirements as the Division or the Office may impose to ensure protection of the public health and safety and the environment.
217. Each experimental practice will be reviewed by the Division at a frequency set forth in the approved permit, but no less frequently than every two and one-half years. After review, the Division may require such reasonable modifications of the experimental practice as are necessary to ensure that the activities fully protect the environment and the public health and safety. Copies of the decision of the Division will be sent to the permittee and will be subject to the provisions for administrative and judicial review of R645-300-200.
218. Revisions or amendments to an experimental practice will be processed in accordance with the requirements of R645-303-220 and approved by the Division. Any revisions which propose significant alterations in the experimental practice will, at a minimum, be subject to notice, hearing, and public participation requirements of R645-300-120 and concurrence by the Office. Revisions that do not propose significant alterations in the experimental practice will not require concurrence by the Office.
220. Mountaintop Removal Mining.
221. R645-302-220 applies to any person who conducts or intends to conduct SURFACE COAL MINING AND RECLAMATION ACTIVITIES by mountaintop removal mining.
222. Mountaintop removal mining means SURFACE COAL MINING AND RECLAMATION ACTIVITIES, where the mining operation removes an entire coal seam or seams running through the upper fraction of a mountain, ridge, or hill, except as provided for in R645-302-227.500, by removing substantially all of the overburden off the bench and creating a level plateau or a gently rolling contour, with no highwalls remaining, and capable of supporting postmining land uses in accordance with the requirements of R645-302-220.
223. The Division may issue approval to conduct mountaintop removal mining, without regard to the requirements of R645-301-537.200, R645-301-552 through R645-301-553.230, R645-301-553.260 through R645-301-553.900, and R645-302-234 to restore the lands disturbed by such mining to their approximate original contour, if it first finds, in writing, on the basis of a complete application, that the following requirements are met:
223.100. The proposed postmining land use of the lands to be affected will be an industrial, commercial, agricultural, residential, or public facility (including recreational facilities) use and, if:
223.110. After consultation with the appropriate land-use planning agencies, if any, the proposed land use is deemed by the Division to constitute an equal or better economic or public use of the affected land compared with the premining use;
223.120. The applicant demonstrates compliance with the requirements for acceptable alternative postmining land uses of R645-301-413.100 through R645-301-413.300;

223.133. Assured of investment in necessary public facilities;
223.134. Supported by commitments from public agencies where appropriate;
223.135. Practicable with respect to private financial capability for completion of the proposed use;
223.136. Planned pursuant to a schedule attached to the reclamation plan so as to integrate the mining operation and reclamation with the postmining land use; and
223.137. Designed by a registered engineer in conformance with professional standards established to assure the stability, drainage, and configuration necessary for the intended use of the site.
223.140. The proposed use would be consistent with adjacent land uses and existing Utah and local land use plans and programs; and
223.150. The Division has provided, in writing, an opportunity of not more than 60 days to review and comment on such proposed use to the governing body of general purpose government in whose jurisdiction the land is located and to any Utah or federal agency which the Division, in its discretion, determines to have an interest in the proposed use;
223.200. The applicant demonstrates that in place of restoration of the land to be affected to the approximate original contour under R645-301-537.200, R645-301-552 through R645-301-553.230, R645-301-553.260 through R645-301-553.900, and R645-302-234, the SURFACE COAL MINING AND RECLAMATION ACTIVITY will be conducted in compliance with the requirements of R645-302-227.
223.300. The requirements of R645-302-227 are made a specific condition of the permit;
223.400. All other requirements of the State Program are met by the proposed operations; and
223.500. The application to conduct SURFACE COAL MINING AND RECLAMATION ACTIVITIES clearly identifies mountaintop removal mining.
224. Any permits incorporating a variance issued under R645-302-220 will be reviewed by the Division to evaluate the progress and development of the SURFACE COAL MINING AND RECLAMATION ACTIVITIES to establish that the operator is proceeding in accordance with the terms of the variance:
224.100. Within the sixth month preceding the third year from the date of its issuance;
224.200. Before each permit renewal; and
224.300. Not later than the middle of each permit term.

227.400. The alternative land use requirements of R645-301-413.100 through R645-301-413.300 and all applicable requirements of R645-301 and R645-302 and the State Program, other than the requirement to restore affected areas to their approximate original contour, are met;
227.500. An outcrop barrier of sufficient width, consisting of the toe of the lowest coal seam, and its associated overburden, are retained to prevent slides and erosion, except that the Division may allow an exemption to the retention of the coal barrier requirement if the following conditions are satisfied:
227.510. The proposed mine site was mined prior to May 3, 1978, and the toe of the lowest seam has been removed; or
227.520. A coal barrier adjacent to a head-of-hollow fill may be removed after the elevation of a head-of-hollow fill attains the elevation of the coal barrier if the head-of-hollow fill provides the stability otherwise ensured by the retention of a coal barrier;
227.600. The final graded slopes on the mined area are less than 1v:5h, so as to create a level plateau or gently rolling configuration, and the outslopes of the plateau do not exceed 1v:2h except where engineering data substantiates, and the Division finds, in writing, and includes in the permit to conduct SURFACE COAL MINING AND RECLAMATION ACTIVITIES under R645-302-220 that a minimum static safety factor of 1.5 will be attained;
227.700. The resulting level or gently rolling contour is graded to drain inward from the outslope, except at specified points where it drains over the outslope in stable and protected channels. The drainage will not be through or over a valley or head-of-hollow fill and natural watercourses below the lowest coal seam mined will not be damaged;
227.800. All waste and acid-forming or toxic-forming materials, including the strata immediately below the coal seam, are covered with nontoxic spoil to prevent pollution and achieve the approved postmining land use; and
227.900. Spoil is placed on the mountaintop bench as necessary to achieve the postmining land use approved under R645-302-227.300 and R645-302-227.400.

270. Variances from Approximate Original Contour Restoration Requirements.
271. The Division may issue approval or, if applicable, a permit for nonmountaintop removal mining in steep slope areas which includes a variance from the requirements of R645-301-537.200, R645-301-552 through R645-301-553.230, R645-301-553.260 through R645-301-553.420, R645-301-553.600 through R645-301-553.900, and R645-302-234 to restore the disturbed areas to their approximate original contour. The permit may contain such a variance only if the Division finds, in writing, that the applicant has demonstrated, on the basis of a complete application, that the following requirements are satisfied:
271.100. The alternative postmining land use requirements of R645-301-413.300 are met;
271.200. All applicable requirements of the State Program, other than the requirements to restore disturbed areas to their appropriate original contour are met;
271.300. After consultation with the appropriate land use agencies, if any, the potential use is shown to constitute an equal or better economic or public use;
271.400. Federal, Utah and local government agencies with an interest in the proposed land use have had an adequate period of time in which to review and comment on the proposed use;
271.500. After reclamation, the lands to be affected by the variance within the permit area will be suitable for an industrial, commercial, residential or public postmining land use (including recreational facilities);
271.600. The surface landowner of the lands within the permit area has knowingly requested, in writing, as part of the permit application, that a variance be granted so as to render the land, after reclamation, suitable for an industrial, commercial, residential or public use (including recreational facilities). The request will be made separately from any surface owner consent given for the operations under R645-301-114 and will show an understanding that the variance could not be granted without the owner's request;
271.700. The watershed of lands within the proposed permit and adjacent areas will be improved by the coal mining and reclamation operations when compared with the condition of the watershed before mining or with its condition if the approximate original contour were to be restored. The watershed will be deemed improved only if:
271.710. The amount of total suspended solids or other pollutants discharged to ground or surface water from the permit area will be reduced, so as to improve the public or private uses or the ecology of such water, or flood hazards within the watershed containing the permit area will be reduced by reduction of the peak flow discharge from precipitation events or thaws; and
271.720. The total volume of flow from the proposed permit area, during every season of the year, will not vary in a way that adversely affects the ecology of any surface water or any existing or planned use of surface or ground water;
271.800. Engineering. The proposed design plan for the variance will be prepared and certified as described under R645-301-512.260. The proposed design plan will also meet the following requirements:
271.810. Unless the highwall is determined to be retained under R645-301-553.650, the highwall will be completely backfilled with spoil material, in a manner which results in a static factor of safety at least 1.3, using standard geotechnical analysis; and
271.820. Only the amount of spoil as is necessary to achieve the postmining land use, ensure the stability of spoil retained on the bench, and meet all other requirements of the Act and R645 Rules will be placed on the mine bench. All spoil not retained on the bench will be placed in accordance with R645-301-211, R645-301-212, R645-301-412.300, R645-301-512.210, R645-301-512.220, R645-301-514.100, R645-301-528.310, R645-301-535.100 through R645-301-535.130, R645-301-535.300 through R645-301-535.500, R645-301-536.300, R645-301-542.720, R645-301-553.240, R645-301-745.100, R645-301-745.300, and R645-301-745.400; and
271.900. After Division approval, the watershed of the permit and adjacent areas is shown to be improved.
272. If a variance is granted under R645-302-270:
272.100. The requirements of R645-302-270 will be included as a specific condition of the permit; and
272.200. The permit will be specifically marked as containing a variance from approximate original contour.
273. A permit incorporating a variance under R645-302-270 will be reviewed by the Division at least every 30 months following the issuance of the permit to evaluate the progress and development of the coal mining and reclamation operations to establish that the operator is proceeding in accordance with the terms of the variance.
274. If the permittee demonstrates to the Division that the coal mining and reclamation operation has been, and continues to be, conducted in compliance with the terms and conditions of the permit, the requirements of the Act, the R645 Rules, and the State Program, the review specified in R645-302-273 need not be held.
275. The terms and conditions of a permit incorporating a variance under R645-302-270 may be modified at any time by the Division, if it determines that more stringent measures are necessary to ensure that the operations involved are conducted in compliance with the requirements of the State Program.

299.200. The program administrator will determine the data needed for each applicant or group of applicants. Data collected and the results provided to the program administrator will be sufficient to satisfy the requirements for:
299.210. The determination of the probable hydrologic consequences of the coal mining and reclamation operations in the proposed permit area and adjacent areas in accordance with R645-301-728 and any other applicable provisions of the R645 Rules; and
299.220. The statement of the results of test borings or core samplings for the proposed permit area in accordance with R645-301-624 and any other applicable provisions of the R645 Rules.
299.300. Data collection and analysis may proceed concurrently with the development of mining and reclamation plans by the operator.
299.400. Data collected under this program will be made publicly available in accordance with R645-300-124.
The rules in R645-302-300 present the minimum requirements for information to be included in the permit application to conduct coal mining and reclamation operations for mining in designated special areas and present procedures to process said permit applications.
310. Prime Farmland. R645-302-300 applies to any person who conducts or intends to conduct coal mining and reclamation operations on prime farmlands historically used for cropland.
311. The rules given under R645-302-300 do not apply to:
311.100. Lands on which coal mining and reclamation operations are conducted pursuant to any permit issued prior to August 3, 1977; or
311.200. Lands on which coal mining and reclamation operations are conducted pursuant to any renewal or revision of a permit issued prior to August 3, 1977; or
311.300. Lands included in any existing coal mining and reclamation operations for which a permit was issued for all or any part thereof prior to August 3, 1977, provided that:
311.310. Such lands are part of a single continuous coal mining and reclamation operation begun under a permit issued before August 3, 1977; and
311.320. The permittee had a legal right to mine the lands prior to August 3, 1977, through ownership, contract, or lease but not including an option to buy, lease, or contract; and
311.330. The lands contain part of a continuous recoverable coal seam that was being mined in a single continuous mining pit (or multiple pits if the lands are proven to be part of a single continuous surface coal mining and reclamation activity) begun under a permit issued prior to August 3, 1977.
312. For purposes of R645-302-300:
312.100. A pit will be deemed to be a single continuous mining pit even if portions of the pit are crossed by a road, pipeline, railroad, or powerline or similar crossing; and
312.200. A single continuous SURFACE COAL MINING AND RECLAMATION ACTIVITY is presumed to consist only of a single continuous mining pit under permit issued prior to August 3, 1977, but may include noncontiguous parcels if the operator can prove by clear and convincing evidence that, prior to August 3, 1977, the noncontiguous parcels were part of a single permitted operation. Clear and convincing evidence includes, but is not limited to, contracts, leases, deeds or other properly executed legal documents (not including options) that specifically treat physically separate parcels as one SURFACE COAL MINING AND RECLAMATION ACTIVITY.
313. Application Contents--Reconnaissance Inspection. All permit applications, whether or not prime farmland is present, will include the results of a reconnaissance inspection of the proposed permit area to indicate whether prime farmland exists. The Division in consultation with the NRCS will determine the nature and extent of the required reconnaissance inspection.
313.100. If the reconnaissance inspection establishes that no land within the proposed permit area is prime farmland historically used for cropland, the applicant will submit a statement that no prime farmland is present. The statement will identify the basis upon which such a conclusion was reached.
313.200. If the reconnaissance inspection indicates that land within the proposed permit area may be prime farmland historically used for cropland, the applicant will determine if a soil survey exists for those lands and whether soil mapping units in the permit area have been designated as prime farmland. If no soil survey exists, the applicant will have a soil survey made of the lands within the permit area which the reconnaissance inspection indicates could be prime farmland. Soil surveys of the detail used by the NRCS for operational conservation planning will be used to identify and locate prime farmland soils.
313.210. If the soil survey indicates that no prime farmland soils are present within the proposed permit area, R645-302-313.100 will apply.
313.220. If the soil survey indicates that prime farmland soils are present within the proposed permit area, R645-302-314 will apply.
314. Application Contents--Prime Farmland. All permit applications for areas in which prime farmland has been identified within the proposed permit area will include the following:
314.100. A soil survey of the permit area according to the standards of the National Cooperative Soil Survey and in accordance with the procedures set forth in U.S. Department of Agriculture Handbooks 436 "Soil Taxonomy" (U.S. Soil Conservation Service, 1975), as amended on March 22, 1982 and October 5, 1982 and 18, "Soil Survey Manual" (U.S. Soil Conservation Service, 1951) as amended on December 18, 1979, May 7, 1980, May 9, 1980, September 11, 1980, June 9, 1981, June 29, 1981, November 16, 1982. The NRCS establishes the standards of the National Cooperative Soil Survey and maintains a National Soils Handbook which gives current acceptable procedures for conducting soil surveys. This National Soils Handbook is available for review at area and Utah NRCS offices.
314.110. U.S. Department of Agriculture Handbooks 436 and 18 are incorporated by reference as they respectively existed on October 5,1982, and November 16,1982.

The soil survey will include a description of soil mapping units and a representative soil profile as determined by the NRCS, including, but not limited to, soil-horizon depths, pH, and the range of soil densities for each prime farmland soil unit within the permit area. Other representative soil-profile descriptions from the locality, prepared according to the standards of the National Cooperative Soil Survey, may be used if their use is approved by the State Conservationist, NRCS. The Division may request the operator to provide information on other physical and chemical soil properties as needed to make a determination that the operator has the technological capability to restore the prime farmland within the permit area to the soil-reconstruction standards of R645-302-317.
314.200. A plan for soil reconstruction, replacement, and stabilization for the purpose of establishing the technological capability of the mine operator to comply with the requirements of R645-302-317.

314.400. The productivity prior to mining, including the average yield of food, fiber, forage, or wood products obtained under a high level of management.
315. Consultation with Secretary of Agriculture. The Secretary of Agriculture has responsibilities with respect to prime farmland soils and has assigned the prime farmland responsibilities arising under the Federal Act to the Chief of the NRCS. The NRCS will carry out consultation and review through the State Conservationist located in Utah.
315.100. The State Conservationist will provide to the Division a list of prime farmland soils, their location, physical and chemical characteristics, crop yields, and associated data necessary to support adequate prime farmland soil descriptions.
315.200. The State Conservationist will assist the Division in describing the nature and extent of the reconnaissance inspection required under R645-302-313.
315.300. Before any permit is issued for areas that include prime farmland, the Division will consult with the State Conservationist. The State Conservationist will provide for the review of, and comment on, the proposed method of soil reconstruction in the plan submitted under R645-302-314. If the State Conservationist considers those methods to be inadequate, then revisions will be suggested to the Division which result in more complete and adequate reconstruction.
316. Issuance of Permit. A permit to conduct coal mining and reclamation operations that include mining and reclamation on designated special areas of prime farmland may be granted by the Division, if it first finds, in writing, upon the basis of a complete application, that:
316.100. The approved proposed postmining land use of these prime farmlands will be cropland;
316.200. The permit incorporates as specific conditions the contents of the plan submitted under R645-302-314, after consideration of any revisions to that plan suggested by the State Conservationist under R645-302-315.300;

316.400. The proposed coal mining and reclamation operations will be conducted in compliance with the requirements of R645-302-317 and other environmental protection performance and reclamation standards for mining and reclamation of prime farmland of the State Program.
316.500. The aggregate total prime farmland acreage shall not be decreased from that which existed prior to mining. Water bodies, if any, to be constructed during mining and reclamation operations must be located within the post-reclamation non-prime farmland portions of the permit area. The creation of any such water bodies must be approved by the Division and the consent of all affected property owners within the permit area must be obtained.
317. Prime Farmland Performance Standards.
317.100. Scope and Purpose. The rules under R645-302-317 set forth special environmental protection performance, reclamation, and design standards for coal mining and reclamation operations on prime farmland.
317.200. Responsibilities of Agencies.
317.210. The NRCS within Utah will establish specifications for prime farmland soil removal, storage, replacement, and reconstruction.
317.220. The Division will use the soil-reconstruction specifications of R645-302-317.210 to carry out its responsibilities under R645-302-310 through R645-302-316 and R645-301-800.
317.300. Applicability. The requirements of the R645-302-317 will not apply to prime farmland that has been excluded in accordance with R645-302-311 and R645-302-312.
317.400. Soil Removal and Stockpiling.
317.410. Prime farmland soils will be removed from the areas to be disturbed before drilling, blasting, or mining.
317.420. The minimum depth of soil and soil materials to be removed and stored for use in the reconstruction of prime farmland will be sufficient to meet the requirements of R645-302-317.520.
317.430. Soil removal and stockpiling operations on prime farmland will be conducted to:
317.431. Separately remove the topsoil, or remove other suitable soil materials where such other soil materials will create a final soil having a greater productive capacity than that which exists prior to mining. If not utilized immediately, this material will be placed in stockpiles separate from the spoil and all other excavated materials; and
317.432. Separately remove the B or C horizon or other suitable soil material to provide the thickness of suitable soil required by R645-302-317.520. If not utilized immediately, each horizon or other material will be stockpiled separately from the spoil and all other excavated materials. Where combinations of such soil materials created by mixing have been shown to be equally or more favorable for plant growth than the B horizon, separate handling is not necessary.
317.440. Stockpiles will be placed within the permit area where they will not be disturbed or be subject to excessive erosion. If left in place for more than 30 days, stockpiles will meet the requirements of R645-301-232, R645-301-233.100, R645-301-234, R645-301-242, and R645-301-243.
317.500. Soil Replacement.
317.510. Soil reconstruction specifications established by the NRCS will be based upon the standards of the National Cooperative Soil Survey and will include, as a minimum, physical and chemical characteristics of reconstructed soils and soil descriptions containing soil-horizon depths, soil densities, soil pH, and other specifications such that reconstructed soils will have the capability of achieving levels of yield equal to, or higher than, those of nonmined prime farmland in the surrounding area.
317.520. The minimum depth of soil and substitute soil material to be reconstructed will be 48 inches, or a lesser depth equal to the depth to a subsurface horizon in the natural soil that inhibits or prevents root penetration, or a greater depth if determined necessary to restore the original soil productive capacity. Soil horizons will be considered as inhibiting or preventing root penetration if their physical or chemical properties or water-supplying capacities cause them to restrict or prevent penetration by roots of plants common to the vicinity of the permit area and if these properties or capacities have little or no beneficial effect on soil productive capacity.
317.530. The operator will replace and regrade the soil horizons or other root-zone material with proper compaction and uniform depth.
317.540. The operator will replace the B horizon, C horizon, or other suitable material specified in R645-302-317.432 to the thickness needed to meet the requirements of R645-302-317.520.
317.550. The operator will replace the topsoil or other suitable soil materials specified in R645-302-317.431 as the final surface soil layer. This surface soil layer will equal or exceed the thickness of the original surface soil layer, as determined by the soil survey.
317.600. Revegetation and Restoration of Soil Productivity.
317.610. Following prime farmland soil replacement, the soil surface will be stabilized with a vegetative cover or other means that effectively controls soil loss by wind and water erosion.
317.620. Prime farmland soil productivity will be restored in accordance with the following provisions:
317.621. Measurement of soil productivity will be initiated within 10 years after completion of soil replacement;
317.622. Soil productivity will be measured on a representative sample or on all of the mined and reclaimed prime farmland area using the reference crop determined under R645-302-317.626. A statistically valid sampling technique at a 90-percent or greater statistical confidence level will be used as approved by the Division in consultation with the NRCS;
317.623. The measurement period for determining average annual crop production (yield) will be a minimum of three crop years prior to release of the operator's performance bond;
317.624. The level of management applied during the measurement period will be the same as the level of management used on nonmined prime farmland in the surrounding area;
317.625. Restoration of soil productivity will be considered achieved when the average yield during the measurement period equals or exceeds the average yield of the reference crop established for the same period for nonmined soils of the same or similar texture or slope phase of the soil series in the surrounding area under equivalent management practices;
317.626. The reference crop on which restoration of soil productivity is proven will be selected from the crops most commonly produced on the surrounding prime farmland. Where row crops are the dominant crops grown on prime farmland in the area, the row crop requiring the greatest rooting depth will be chosen as one of the reference crops;
317.627. Reference crop yields for a given crop season are to be determined from:
317.627.1. The current yield records of representative local farms in the surrounding area, with concurrence by the NRCS; or
317.627.2. The average county yields recognized by the U.S. Department of Agriculture, which have been adjusted by the NRCS for local yield variation within the county that is associated with differences between nonmined prime farmland soil and all other soils that produce the reference crop; and
317.628. Under either procedure in R645-302-317.627, the average reference crop yield may be adjusted, with the concurrence of the NRCS, for:
317.628.1. Disease, pest, and weather-induced seasonal variations; or
317.628.2. Differences in specific management practices where the overall management practices of the crops being compared are equivalent.
320. Alluvial Valley Floors. R645-302-320 applies to any person who conducts or intends to conduct coal mining and reclamation operations on areas or adjacent to areas designated as alluvial valley floors.
321. Alluvial Valley Floor Determination.
321.100. Before applying for a permit to conduct, or before conducting surface coal mining and reclamation operations within a valley holding a stream or in a location where the adjacent area includes any stream, the applicant shall either affirmatively demonstrate, based on available data, the presence of an alluvial valley floor, or submit to the Division the results of a field investigation of the proposed permit and adjacent area. The field investigations shall include sufficiently detailed geologic, hydrologic, land use, soils, and vegetation studies on areas required to be investigated by the Division, after consultation with the applicant, to enable the Division to make an evaluation regarding the existence of the probable alluvial valley floor in the proposed permit or adjacent area and to determine which areas, if any, require more detailed study in order to allow the Division to make a final determination regarding the existence of an alluvial valley floor.
321.200. Studies performed during the investigation by the applicant or subsequent studies as required of the applicant by the Division shall include an appropriate combination, adapted to site-specific conditions, of:
321.210. Mapping of unconsolidated stream-laid deposits holding streams including, but not limited to, geologic maps of unconsolidated deposits, and stream-laid deposits, maps of streams, delineation of surface watersheds and directions of shallow groundwater flows through and into the unconsolidated deposits, topography showing local and regional terrace levels, and topography of terraces, flood plains and channels showing surface drainage patterns;
321.220. Mapping of all lands included in the area in accordance with R645-302-321 and subject to agricultural activities, showing the area in which different types of agricultural lands, such as flood irrigated lands, pasture lands and undeveloped rangelands, exist, and accompanied by measurements of vegetation in terms of productivity and type;

321.260. Analysis of a series of aerial photographs, including color infrared imagery flown at a time of year to show any late summer and fall differences between upland and valley floor vegetative growth and of a scale adequate for reconnaissance identification of areas that may be alluvial valley floors.
321.300. Based on the investigations conducted under R645-302-321.200, the Division will make a determination of the extent of any alluvial valley floors within the study area and whether any stream in the study area may be excluded from further consideration as lying within an alluvial valley floor. The Division will determine that an alluvial valley floor exists if it finds that:
321.310. Unconsolidated streamlaid deposits holding streams are present; and,
321.320. There is sufficient water to support agricultural activities as evidenced by:
321.321. The existence of flood irrigation in the area in question or its historical use;
321.322. The capability of an area to be flood irrigated, based on streamflow water yield, soils, water quality, and topography; or,
321.323. Subirrigation of the lands in question, derived from the groundwater system of the valley floor.
322. Application Contents for Operations Affecting Designated Alluvial Valley Floors.
322.100. If land within the permit area or adjacent area is identified as an alluvial valley floor and the proposed coal mining and reclamation operation may affect an alluvial valley floor or waters supplied to an alluvial valley floor, the applicant will submit a complete application for the proposed coal mining and reclamation operation to be used by the Division together with other relevant information, including the information required by R645-302-321, as a basis for approval or denial of the permit.
322.200. The complete application will include detailed surveys and baseline data required by the Division for a determination of:

322.350. Plans showing how the operations will avoid, during mining and reclamation, interruption, discontinuance or preclusion of farming on the alluvial valley floors unless the premining land use has been undeveloped rangeland which is not significant to farming and will not materially damage the quantity or quality of water in surface and groundwater systems that supply alluvial valley floors;
322.360. Maps showing farms that could be affected by the mining and, if any farm includes an alluvial valley floor, statements of the type and quantity of agricultural activity performed on the alluvial valley floor and its relationship to the farm's total agricultural activity including an economic analysis; and

323.100. No permit or permit change application for coal mining and reclamation operations in Utah will be approved by the Division unless the application demonstrates and the Division finds in writing, on the basis of information set forth in the application that:
323.110. The proposed operations would not interrupt, discontinue, or preclude farming on an alluvial valley floor unless the premining land use has been undeveloped rangeland which is not significant to farming on the alluvial valley floor, or unless the area of an affected alluvial valley floor is small and provides, or may provide, negligible support for production of one or more farms; provided however, R645-302-323.100 does not apply to those lands which were identified in a reclamation plan approved by the State Program prior to August 3, 1977, for any coal mining and reclamation operation that, in the year preceding August 3, 1977;
323.111. Produced coal in commercial quantities and was located within or adjacent to alluvial valley floors, or
323.112. Obtained specific permit approval by the Division to conduct coal mining and reclamation operations within an alluvial valley floor;
323.120. The proposed operations would not materially damage the quantity and quality of water in surface and underground water systems that supply those alluvial valley floors or portions of alluvial valley floors which are:
323.121. Included in R645-302-323.110; or
323.122. Outside the permit area of an existing or proposed coal mining and reclamation operation;
323.130. The proposed operations would be conducted in accordance with all applicable requirements of the State Program; and
323.140. Any change in the land use of the lands covered by the proposed permit area from its premining use in or adjacent to alluvial valley floors will not interfere with or preclude the reestablishment of the essential hydrologic functions of the alluvial valley floor.
323.200. The significance of the impact of the proposed operations on farming will be based on the relative importance of the vegetation and water of the developed grazed or hayed alluvial valley floor area to the farm's production, or any more stringent criteria established by the Division as suitable for site-specific protection of agricultural activities in alluvial valley floors. The effect of the proposed operations on farming will be concluded to be significant if they would remove from production, over the life of the mine, a proportion of the farm's production that would decrease the expected annual income from agricultural activities normally conducted at the farm.
323.300. Criteria for determining whether a coal mining and reclamation operation will materially damage the quantity or quality of waters subject to R645-302-323.310 and R645-302-323.320 include, but are not limited to:
323.310. Potential increases in the concentration of total dissolved solids of waters supplied to an alluvial valley floor, as measured by specific conductance in millimhos, to levels above the threshold value at which crop yields decrease, as specified in Maas and Hoffman, "Crop Salt Tolerance - Current Assessment," Table 1, "Salt Tolerance of Agricultural Crops," which is incorporated by reference unless the applicant demonstrates compliance with R645-302-323.320.
323.311. Salt tolerances for agricultural crops have been published by E.V. Maas and G.J. Hoffman, in a paper titled "Crop Salt Tolerance - Current Assessment" contained in The Journal of The Irrigation and Drainage Division, American Society of Civil Engineers, pages 115 through 134, June, 1977. Table 1, giving threshold salinity values is presented on pages 22 through 125.
323.312. The Maas and Hoffman publication is on file and available for inspection and copying at the Division office;
323.320. Potential increases in the concentration of total dissolved solids of waters supplied to an alluvial valley floor in excess of those incorporated by reference in R645-302-323.310 will not be allowed unless the applicant demonstrates, through testing related to the production of crops grown in the locality, that the proposed operations will not cause increases that will result in crop yield decreases;
323.321. For types of vegetation not listed in Maas and Hoffman as specified by the Division, based upon consideration of observed correlation between total dissolved solid concentrations in water and crop yield declines, taking into account the accuracy of the correlations;
323.322. Potential increases in the average depth to water saturated zones (during the growing season) located within the root zone of the alluvial valley floor that would reduce the amount of subirrigation land compared to premining conditions;
323.323. Potential decreases in surface flows that would reduce the amount of irrigable land compared to premining conditions; and
323.324. Potential changes in the surface or groundwater systems that reduce the area available to agriculture as a result of flooding or increased saturation of the root zone.
323.400. For the purposes of R645-302-323, a farm is one or more land units on which agricultural activities are conducted. A farm is generally considered to be the combination of land units with acreage and boundaries in existence prior to August 3, 1977, or, if established after August 3, 1977, with those boundaries based on enhancement of the farm's agricultural productivity and not related to coal mining and reclamation operations.
324. Performance Standards.
324.100. Essential Hydrologic Functions.
324.110. The operator of a coal mining and reclamation operation will minimize disturbances to the hydrologic balance by preserving throughout the mining and reclamation process the essential hydrologic functions of an alluvial valley floor not within the permit area.
324.120. The operator of a coal mining and reclamation operation will minimize disturbances to the hydrologic balance within the permit area by reestablishing throughout the mining and reclamation process the essential hydrologic functions of alluvial valley floors.
324.200. Protection of Agricultural Activities.
324.210. Prohibitions. Coal mining and reclamation operations will not:
324.211. Interrupt, discontinue or preclude farming on alluvial valley floors; or
324.212. Cause material damage to the quantity or quality of water in surface or underground water systems that supply alluvial valley floors.
324.220. Statutory Exclusions. The prohibitions of R645-302-324.210 will not apply:
324.221. Where the premining land use of an alluvial valley floor is undeveloped rangeland which is not significant to farming;
324.222. Where farming on the alluvial valley floor that would be affected by the coal mining and reclamation operation is of such small acreage as to be of negligible impact on the farm's agricultural production;
324.223. To any coal mining and reclamation operation that, in the year preceding August 3, 1977:
324.223.1. Produced coal in commercial quantities and was located within or adjacent to a alluvial valley floor; or
324.223.2. Obtained specific permit approval by the Division to conduct coal mining and reclamation operations within an alluvial valley floor; or
324.224. To any land that is the subject of an application for renewal or revision of a permit issued pursuant to the Act which is an extension of the original permit, insofar as:
324.224.1. The land was previously identified in a reclamation plan submitted under R645-301, and
324.224.2. The original permit area was excluded from the protection of R645-302-324.210 for a reason set forth in R645-302-324.223.
324.310. A monitoring system will be installed, maintained, and operated by the permittee on all alluvial valley floors during coal mining and reclamation operations and continued until all bonds are released in accordance with R645-301-800. The monitoring system will provide sufficient information to allow the Division to determine that:
324.311. The essential hydrologic functions of alluvial valley floors are being preserved outside the permit area or reestablished within the permit area throughout the mining and reclamation process in accordance with R645-302-324.100;
324.312. Farming on lands protected under R645-302-324.200 is not being interrupted, discontinued, or precluded; and
324.313. The operation is not causing material damage to the quantity or quality of water in the surface or underground systems that supply alluvial valley floors protected under R645-302-324.200.
324.320. Monitoring will be conducted at adequate frequencies to indicate long-term trends that could affect compliance with R645-302-324.100 and R645-302-324.200.
324.330. All monitoring data collected and analyses thereof will routinely be made available to the Division.
