§ 226

((a)) ** Leasing authorized** ((1)) ** In general** Any parcel of land subject to disposition under this chapter that is known or believed to contain oil or gas deposits shall be made available for leasing, subject to paragraph (2), by the Secretary of the Interior, not later than 18 months after the date of receipt by the Secretary of an expression of interest in leasing the applicable parcel of land available for disposition under this section, if the Secretary determines that the parcel of land is open to oil or gas leasing under the approved resource management plan applicable to the planning area in which the parcel of land is located that is in effect on the date on which the expression of interest was submitted to the Secretary (referred to in this subsection as the “approved resource management plan”). ((2)) ** Resource management plans** ((A)) ** Lease terms and conditions** A lease issued by the Secretary under this section with respect to an applicable parcel of land made available for leasing under paragraph (1)— ((i)) shall be subject to the terms and conditions of the approved resource management plan; and ((ii)) may not require any stipulations or mitigation requirements not included in the approved resource management plan. ((B)) ** Effect of amendment** The initiation of an amendment to an approved resource management plan shall not prevent or delay the Secretary from making the applicable parcel of land available for leasing in accordance with that approved resource management plan if the other requirements of this section have been met, as determined by the Secretary. ((b)) ** Lands within known geologic structure of a producing oil or gas field; lands within special tar sand areas; competitive bidding; royalties** ((1)) ((A)) All lands to be leased which are not subject to leasing under paragraphs (2) and (3) of this subsection shall be leased as provided in this paragraph to the highest responsible qualified bidder by competitive bidding under general regulations in units of not more than 2,560 acres, except in Alaska, where units shall be not more than 5,760 acres. Such units shall be as nearly compact as possible. Lease sales shall be conducted by oral bidding, except as provided in subparagraph (C). Lease sales shall be held for each State where eligible lands are available at least quarterly and more frequently if the Secretary of the Interior determines such sales are necessary. For purposes of the previous sentence, the term “eligible lands” means all lands that are subject to leasing under this chapter and are not excluded from leasing by a statutory prohibition, and the term “available”, with respect to eligible lands, means those lands that have been designated as open for leasing under a land use plan developed under and that have been nominated for leasing through the submission of an expression of interest, are subject to drainage in the absence of leasing, or are otherwise designated as available pursuant to regulations adopted by the Secretary. A lease shall be conditioned upon the payment of a royalty at a rate of not less than 12½ per centum in amount or value of the production removed or sold from the lease. The Secretary shall accept the highest bid from a responsible qualified bidder which is equal to or greater than the national minimum acceptable bid, without evaluation of the value of the lands proposed for lease. Leases shall be issued within 60 days following payment by the successful bidder of the remainder of the bonus bid, if any, and the annual rental for the first lease year. All bids for less than the national minimum acceptable bid shall be rejected. Lands for which no bids are received or for which the highest bid is less than the national minimum acceptable bid shall be offered promptly within 30 days for leasing under subsection (c) of this section and shall remain available for leasing for a period of 2 years after the competitive lease sale. ((B)) The national minimum acceptable bid shall be $10 per acre during the 10-year period beginning on . Thereafter, the Secretary, subject to paragraph (2)(B), may establish by regulation a higher national minimum acceptable bid for all leases based upon a finding that such action is necessary: (i) to enhance financial returns to the United States; and (ii) to promote more efficient management of oil and gas resources on Federal lands. Ninety days before the Secretary makes any change in the national minimum acceptable bid, the Secretary shall notify the Committee on Natural Resources of the United States House of Representatives and the Committee on Energy and Natural Resources of the United States Senate. The proposal or promulgation of any regulation to establish a national minimum acceptable bid shall not be considered a major Federal action subject to the requirements of . ((C)) In order to diversify and expand the Nation’s onshore leasing program to ensure the best return to the Federal taxpayer, reduce fraud, and secure the leasing process, the Secretary may conduct onshore lease sales through Internet-based bidding methods. Each individual Internet-based lease sale shall conclude within 7 days. ((2)) ((A)) ((i)) If the lands to be leased are within a special tar sand area, they shall be leased to the highest responsible qualified bidder by competitive bidding under general regulations in units of not more than 5,760 acres, which shall be as nearly compact as possible, upon the payment by the lessee of such bonus as may be accepted by the Secretary. ((ii)) Royalty shall be 12½ per centum in amount or value of production removed or sold from the lease, subject to subsection (k)(1)(c). ((iii)) The Secretary may lease such additional lands in special tar sand areas as may be required in support of any operations necessary for the recovery of tar sands. ((iv)) No lease issued under this paragraph shall be included in any chargeability limitation associated with oil and gas leases. ((B)) For any area that contains any combination of tar sand and oil or gas (or both), the Secretary may issue under this chapter, separately— ((i)) a lease for exploration for and extraction of tar sand; and ((ii)) a lease for exploration for and development of oil and gas. ((C)) A lease issued for tar sand shall be issued using the same bidding process, annual rental, and posting period as a lease issued for oil and gas, except that the minimum acceptable bid required for a lease issued for tar sand shall be $10 per acre. ((D)) The Secretary may waive, suspend, or alter any requirement under that a permittee under a permit authorizing prospecting for tar sand must exercise due diligence, to promote any resource covered by a combined hydrocarbon lease. ((3)) ((A)) If the United States held a vested future interest in a mineral estate that, immediately prior to becoming a vested present interest, was subject to a lease under which oil or gas was being produced, or had a well capable of producing, in paying quantities at an annual average production volume per well per day of either not more than 15 barrels per day of oil or condensate, or not more than 60,000 cubic feet of gas, the holder of the lease may elect to continue the lease as a noncompetitive lease under subsection (c)(1). ((B)) An election under this paragraph is effective— ((i)) in the case of an interest which vested after , and on or before , if the election is made before the date that is 1 year after ; ((ii)) in the case of an interest which vests within 1 year after , if the election is made before the date that is 2 years after ; and ((iii)) in any case other than those described in clause (i) or (ii), if the election is made prior to the interest becoming a vested present interest. ((C)) Notwithstanding the consent requirement referenced in , the Secretary shall issue a noncompetitive lease under subsection (c)(1) to a holder who makes an election under subparagraph (A) and who is qualified to hold a lease under this chapter. Such lease shall be subject to all terms and conditions under this chapter that are applicable to leases issued under subsection (c)(1). ((D)) A lease issued pursuant to this paragraph shall continue so long as oil or gas continues to be produced in paying quantities. ((E)) This paragraph shall apply only to those lands under the administration of the Secretary of Agriculture where the United States acquired an interest in such lands pursuant to the Act of ( and following). ((c)) ** Lands subject to leasing under subsection (b); first qualified applicant** ((1)) If the lands to be leased are not leased under subsection (b)(1) of this section or are not subject to competitive leasing under subsection (b)(2) of this section, the person first making application for the lease who is qualified to hold a lease under this chapter shall be entitled to a lease of such lands without competitive bidding, upon payment of a non-refundable application fee of at least $75. A lease under this subsection shall be conditioned upon the payment of a royalty at a rate of 12.5 percent in amount or value of the production removed or sold from the lease. Leases shall be issued within 60 days of the date on which the Secretary identifies the first responsible qualified applicant. ((2)) ((A)) Lands (i) which were posted for sale under subsection (b)(1) of this section but for which no bids were received or for which the highest bid was less than the national minimum acceptable bid and (ii) for which, at the end of the period referred to in subsection (b)(1) of this section no lease has been issued and no lease application is pending under paragraph (1) of this subsection, shall again be available for leasing only in accordance with subsection (b)(1) of this section. ((B)) The land in any lease which is issued under paragraph (1) of this subsection or under subsection (b)(1) of this section which lease terminates, expires, is cancelled or is relinquished shall again be available for leasing only in accordance with subsection (b)(1) of this section. ((d)) ** Annual rentals** All leases issued under this section, as amended by the Federal Onshore Oil and Gas Leasing Reform Act of 1987, shall be conditioned upon payment by the lessee of a rental of not less than $3 per acre per year during the 2-year period beginning on the date the lease begins for new leases, and after the end of that 2-year period, $5 per acre per year for the following 6-year period, and not less than $15 per acre per year thereafter, or, in the case of a lease issued during the 10-year period beginning on , $3 per acre per year during the 2-year period beginning on the date the lease begins, and after the end of that 2-year period, $5 per acre per year for the following 6-year period, and $15 per acre per year thereafter. A minimum royalty in lieu of rental of not less than the rental which otherwise would be required for that lease year shall be payable at the expiration of each lease year beginning on or after a discovery of oil or gas in paying quantities on the lands leased.August 16, 20222022-08-16 ((e)) ** Primary terms** Competitive and noncompetitive leases issued under this section shall be for a primary term of 10 years: , That competitive leases issued in special tar sand areas shall also be for a primary term of ten years. Each such lease shall continue so long after its primary term as oil or gas is produced in paying quantities. Any lease issued under this section for land on which, or for which under an approved cooperative or unit plan of development or operation, actual drilling operations were commenced prior to the end of its primary term and are being diligently prosecuted at that time shall be extended for two years and so long thereafter as oil or gas is produced in paying quantities.Provided, however ((f)) ** Notice of proposed action; posting of notice; terms and maps** At least 45 days before offering lands for lease under this section, and at least 30 days before approving applications for permits to drill under the provisions of a lease or substantially modifying the terms of any lease issued under this section, the Secretary shall provide notice of the proposed action. Such notice shall be posted in the appropriate local office of the leasing and land management agencies. Such notice shall include the terms or modified lease terms and maps or a narrative description of the affected lands. Where the inclusion of maps in such notice is not practicable, maps of the affected lands shall be made available to the public for review. Such maps shall show the location of all tracts to be leased, and of all leases already issued in the general area. The requirements of this subsection are in addition to any public notice required by other law. ((g)) ** Regulation of surface-disturbing activities; approval of plan of operations; bond or surety; failure to comply with reclamation requirements as barring lease; opportunity to comply with requirements** The Secretary of the Interior, or for National Forest lands, the Secretary of Agriculture, shall regulate all surface-disturbing activities conducted pursuant to any lease issued under this chapter, and shall determine reclamation and other actions as required in the interest of conservation of surface resources. No permit to drill on an oil and gas lease issued under this chapter may be granted without the analysis and approval by the Secretary concerned of a plan of operations covering proposed surface-disturbing activities within the lease area. The Secretary concerned shall, by rule or regulation, establish such standards as may be necessary to ensure that an adequate bond, surety, or other financial arrangement will be established prior to the commencement of surface-disturbing activities on any lease, to ensure the complete and timely reclamation of the lease tract, and the restoration of any lands or surface waters adversely affected by lease operations after the abandonment or cessation of oil and gas operations on the lease. The Secretary shall not issue a lease or leases or approve the assignment of any lease or leases under the terms of this section to any person, association, corporation, or any subsidiary, affiliate, or person controlled by or under common control with such person, association, or corporation, during any period in which, as determined by the Secretary of the Interior or Secretary of Agriculture, such entity has failed or refused to comply in any material respect with the reclamation requirements and other standards established under this section for any prior lease to which such requirements and standards applied. Prior to making such determination with respect to any such entity the concerned Secretary shall provide such entity with adequate notification and an opportunity to comply with such reclamation requirements and other standards and shall consider whether any administrative or judicial appeal is pending. Once the entity has complied with the reclamation requirement or other standard concerned an oil or gas lease may be issued to such entity under this chapter. ((h)) ** National Forest System Lands** The Secretary of the Interior may not issue any lease on National Forest System Lands reserved from the public domain over the objection of the Secretary of Agriculture. ((i)) ** Termination** No lease issued under this section which is subject to termination because of cessation of production shall be terminated for this cause so long as reworking or drilling operations which were commenced on the land prior to or within sixty days after cessation of production are conducted thereon with reasonable diligence, or so long as oil or gas is produced in paying quantities as a result of such operations. No lease issued under this section shall expire because operations or production is suspended under any order, or with the consent, of the Secretary. No lease issued under this section covering lands on which there is a well capable of producing oil or gas in paying quantities shall expire because the lessee fails to produce the same unless the lessee is allowed a reasonable time, which shall be not less than sixty days after notice by registered or certified mail, within which to place such well in producing status or unless, after such status is established, production is discontinued on the leased premises without permission granted by the Secretary under the provisions of this chapter. ((j)) ** Drainage agreements; primary term of lease, extension** Whenever it appears to the Secretary that lands owned by the United States are being drained of oil or gas by wells drilled on adjacent lands, he may negotiate agreements whereby the United States, or the United States and its lessees, shall be compensated for such drainage. Such agreements shall be made with the consent of the lessees, if any, affected thereby. If such agreement is entered into, the primary term of any lease for which compensatory royalty is being paid, or any extension of such primary term, shall be extended for the period during which such compensatory royalty is paid and for a period of one year from discontinuance of such payment and so long thereafter as oil or gas is produced in paying quantities. ((k)) ** Mining claims; suspension of running time of lease** If, during the primary term or any extended term of any lease issued under this section, a verified statement is filed by any mining claimant pursuant to subsection (c) of , whether such filing occur prior to or thereafter, asserting the existence of a conflicting unpatented mining claim or claims upon which diligent work is being prosecuted as to any lands covered by the lease, the running of time under such lease shall be suspended as to the lands involved from the first day of the month following the filing of such verified statement until a final decision is rendered in the matter.section 527 of this titleSeptember 2, 19601960-09-02 ((l)) ** Exchange of leases; conditions** The Secretary of the Interior shall, upon timely application therefor, issue a new lease in exchange for any lease issued for a term of twenty years, or any renewal thereof, or any lease issued prior to , in exchange for a twenty-year lease, such new lease to be for a primary term of five years and so long thereafter as oil or gas is produced in paying quantities and at a royalty rate of not less than 12½ per centum in amount or value of the production removed or sold from such leases, except that the royalty rate shall be 12½ per centum in amount or value of the production removed or sold from said leases as to (1) such leases, or such parts of the lands subject thereto and the deposits underlying the same, as are not believed to be within the productive limits of any producing oil or gas deposit, as such productive limits are found by the Secretary to have existed on ; and (2) any production on a lease from an oil or gas deposit which was discovered after , by a well or wells drilled within the boundaries of the lease, and which is determined by the Secretary to be a new deposit; and (3) any production on or allocated to a lease pursuant to an approved cooperative or unit plan of development or operation from an oil or gas deposit which was discovered after , on land committed to such plan, and which is determined by the Secretary to be a new deposit, where such lease, or a lease for which it is exchanged, was included in such plan at the time of discovery or was included in a duly executed and filed application for the approval of such plan at the time of discovery.August 8, 19461946-08-08August 8, 19461946-08-08May 27, 19411941-05-27May 27, 19411941-05-27 ((m)) ** Cooperative or unit plan; authority of Secretary of the Interior to alter or modify; communitization or drilling agreements; term of lease, conditions; Secretary to approve operating, drilling or development contracts, and subsurface storage** For the purpose of more properly conserving the natural resources of any oil or gas pool, field, or like area, or any part thereof (whether or not any part of said oil or gas pool, field, or like area, is then subject to any cooperative or unit plan of development or operation), lessees thereof and their representatives may unite with each other, or jointly or separately with others, in collectively adopting and operating under a cooperative or unit plan of development or operation of such pool, field, or like area, or any part thereof, whenever determined and certified by the Secretary of the Interior to be necessary or advisable in the public interest. The Secretary is thereunto authorized, in his discretion, with the consent of the holders of leases involved, to establish, alter, change, or revoke drilling, producing, rental, minimum royalty, and royalty requirements of such leases and to make such regulations with reference to such leases, with like consent on the part of the lessees, in connection with the institution and operation of any such cooperative or unit plan as he may deem necessary or proper to secure the proper protection of the public interest. The Secretary may provide that oil and gas leases hereafter issued under this chapter shall contain a provision requiring the lessee to operate under such a reasonable cooperative or unit plan, and he may prescribe such a plan under which such lessee shall operate, which shall adequately protect the rights of all parties in interest, including the United States. Any plan authorized by the preceding paragraph which includes lands owned by the United States may, in the discretion of the Secretary, contain a provision whereby authority is vested in the Secretary of the Interior, or any such person, committee, or State or Federal officer or agency as may be designated in the plan, to alter or modify from time to time the rate of prospecting and development and the quantity and rate of production under such plan. All leases operated under any such plan approved or prescribed by the Secretary shall be excepted in determining holdings or control under the provisions of any section of this chapter. When separate tracts cannot be independently developed and operated in conformity with an established well-spacing or development program, any lease, or a portion thereof, may be pooled with other lands, whether or not owned by the United States, under a communitization or drilling agreement providing for an apportionment of production or royalties among the separate tracts of land comprising the drilling or spacing unit when determined by the Secretary of the Interior to be in the public interest, and operations or production pursuant to such an agreement shall be deemed to be operations or production as to each such lease committed thereto. Any lease issued for a term of twenty years, or any renewal thereof, or any portion of such lease that has become the subject of a cooperative or unit plan of development or operation of a pool, field, or like area, which plan has the approval of the Secretary of the Interior, shall continue in force until the termination of such plan. Any other lease issued under any section of this chapter which has heretofore or may hereafter be committed to any such plan that contains a general provision for allocation of oil or gas shall continue in force and effect as to the land committed so long as the lease remains subject to the plan: , That production is had in paying quantities under the plan prior to the expiration date of the term of such lease. Any lease heretofore or hereafter committed to any such plan embracing lands that are in part within and in part outside of the area covered by any such plan shall be segregated into separate leases as to the lands committed and the lands not committed as of the effective date of unitization: , That any such lease as to the nonunitized portion shall continue in force and effect for the term thereof but for not less than two years from the date of such segregation and so long thereafter as oil or gas is produced in paying quantities. The minimum royalty or discovery rental under any lease that has become subject to any cooperative or unit plan of development or operation, or other plan that contains a general provision for allocation of oil or gas, shall be payable only with respect to the lands subject to such lease to which oil or gas shall be allocated under such plan. Any lease which shall be eliminated from any such approved or prescribed plan, or from any communitization or drilling agreement authorized by this section, and any lease which shall be in effect at the termination of any such approved or prescribed plan, or at the termination of any such communitization or drilling agreement, unless relinquished, shall continue in effect for the original term thereof, but for not less than two years, and so long thereafter as oil or gas is produced in paying quantities.ProvidedProvided, however The Secretary of the Interior is hereby authorized, on such conditions as he may prescribe, to approve operating, drilling, or development contracts made by one or more lessees of oil or gas leases, with one or more persons, associations, or corporations whenever, in his discretion, the conservation of natural products or the public convenience or necessity may require it or the interests of the United States may be best subserved thereby. All leases operated under such approved operating, drilling, or development contracts, and interests thereunder, shall be excepted in determining holdings or control under the provisions of this chapter. The Secretary of the Interior, to avoid waste or to promote conservation of natural resources, may authorize the subsurface storage of oil or gas, whether or not produced from federally owned lands, in lands leased or subject to lease under this chapter. Such authorization may provide for the payment of a storage fee or rental on such stored oil or gas or, in lieu of such fee or rental, for a royalty other than that prescribed in the lease when such stored oil or gas is produced in conjunction with oil or gas not previously produced. Any lease on which storage is so authorized shall be extended at least for the period of storage and so long thereafter as oil or gas not previously produced is produced in paying quantities. ((n)) ** Conversion of oil and gas leases and claims on hydrocarbon resources to combined hydrocarbon leases for primary term of 10 years; application** ((1)) ((A)) The owner of (1) an oil and gas lease issued prior to , or (2) a valid claim to any hydrocarbon resources leasable under this section based on a mineral location made prior to , and located within a special tar sand area shall be entitled to convert such lease or claim to a combined hydrocarbon lease for a primary term of ten years upon the filing of an application within two years from , containing an acceptable plan of operations which assures reasonable protection of the environment and diligent development of those resources requiring enhanced recovery methods of development or mining. For purposes of conversion, no claim shall be deemed invalid solely because it was located as a placer location rather than a lode location or vice versa, notwithstanding any previous adjudication on that issue. ((B)) The Secretary shall issue final regulations to implement this section within six months of . If any oil and gas lease eligible for conversion under this section would otherwise expire after , and before six months following the issuance of implementing regulations, the lessee may preserve his conversion right under such lease for a period ending six months after the issuance of implementing regulations by filing with the Secretary, before the expiration of the lease, a notice of intent to file an application for conversion. Upon submission of a complete plan of operations in substantial compliance with the regulations promulgated by the Secretary for the filing of such plans, the Secretary shall suspend the running of the term of any oil and gas lease proposed for conversion until the plan is finally approved or disapproved. The Secretary shall act upon a proposed plan of operations within fifteen months of its submittal. ((C)) When an existing oil and gas lease is converted to a combined hydrocarbon lease, the royalty shall be that provided for in the original oil and gas lease and for a converted mining claim, 12½ per centum in amount or value of production removed or sold from the lease. ((2)) Except as provided in this section, nothing in the Combined Hydrocarbon Leasing Act of 1981 shall be construed to diminish or increase the rights of any lessee under any oil and gas lease issued prior to . ((o)) ** Certain outstanding oil and gas deposits** ((1)) Prior to the commencement of surface-disturbing activities relating to the development of oil and gas deposits on lands described under paragraph (5), the Secretary of Agriculture shall require, pursuant to regulations promulgated by the Secretary, that such activities be subject to terms and conditions as provided under paragraph (2). ((2)) The terms and conditions referred to in paragraph (1) shall require that reasonable advance notice be furnished to the Secretary of Agriculture at least 60 days prior to the commencement of surface disturbing activities. ((3)) Advance notice under paragraph (2) shall include each of the following items of information: ((A)) A designated field representative. ((B)) A map showing the location and dimensions of all improvements, including but not limited to, well sites and road and pipeline accesses. ((C)) A plan of operations, of an interim character if necessary, setting forth a schedule for construction and drilling. ((D)) A plan of erosion and sedimentation control. ((E)) Proof of ownership of mineral title. ((4)) The person proposing to develop oil and gas deposits on lands described under paragraph (5) shall either— ((A)) permit the Secretary to market merchantable timber owned by the United States on lands subject to such activities; or ((B)) arrange to purchase merchantable timber on lands subject to such surface disturbing activities from the Secretary of Agriculture, or otherwise arrange for the disposition of such merchantable timber, upon such terms and upon such advance notice of the items referred to in subparagraphs (A) through (E) of paragraph (3) as the Secretary may accept. ((5)) ((A)) The lands referred to in this subsection are those lands referenced in subparagraph (B) which are under the administration of the Secretary of Agriculture where the United States acquired an interest in such lands pursuant to the Act of ( and following), but does not have an interest in oil and gas deposits that may be present under such lands. This subsection does not apply to any such lands where, under the provisions of its acquisition of an interest in the lands, the United States is to acquire any oil and gas deposits that may be present under such lands in the future but such interest has not yet vested with the United States. ((B)) This subsection shall only apply in the Allegheny National Forest. ((p)) ** Deadlines for consideration of applications for permits** ((1)) ** In general** Not later than 10 days after the date on which the Secretary receives an application for any permit to drill, the Secretary shall— ((A)) notify the applicant that the application is complete; or ((B)) notify the applicant that information is missing and specify any information that is required to be submitted for the application to be complete. ((2)) ** Issuance or deferral** Not later than 30 days after the applicant for a permit has submitted a complete application, the Secretary shall— ((A)) issue the permit, if the requirements under the National Environmental Policy Act of 1969 [ et seq.] and other applicable law have been completed within such timeframe; or ((B)) defer the decision on the permit and provide to the applicant a notice— ((i)) that specifies any steps that the applicant could take for the permit to be issued; and ((ii)) a list of actions that need to be taken by the agency to complete compliance with applicable law together with timelines and deadlines for completing such actions. ((3)) ** Requirements for deferred applications** ((A)) ** In general** If the Secretary provides notice under paragraph (2)(B), the applicant shall have a period of 2 years from the date of receipt of the notice in which to complete all requirements specified by the Secretary, including providing information needed for compliance with the National Environmental Policy Act of 1969. ((B)) ** Issuance of decision on permit** If the applicant completes the requirements within the period specified in subparagraph (A), the Secretary shall issue a decision on the permit not later than 10 days after the date of completion of the requirements described in subparagraph (A), unless compliance with the National Environmental Policy Act of 1969 and other applicable law has not been completed within such timeframe. ((C)) ** Denial of permit** If the applicant does not complete the requirements within the period specified in subparagraph (A) or if the applicant does not comply with applicable law, the Secretary shall deny the permit. ((4)) ** Term** A permit to drill approved under this subsection shall be valid for a single, non-renewable 4-year period beginning on the date that the permit to drill is approved. ((q)) ** Commingling of production** The Secretary of the Interior shall approve applications allowing for the commingling of production from 2 or more sources (including the area of an oil and gas lease, the area included in a drilling spacing unit, a unit participating area, a communitized area, or non-Federal property) before production reaches the point of royalty measurement regardless of ownership, the royalty rates, and the number or percentage of acres for each source if the applicant agrees to install measurement devices for each source, utilize an allocation method that achieves volume measurement uncertainty levels within plus or minus 2 percent during the production phase reported on a monthly basis, or utilize an approved periodic well testing methodology. Production from multiple oil and gas leases, drilling spacing units, communitized areas, or participating areas from a single wellbore shall be considered a single source. Nothing in this subsection shall prevent the Secretary of the Interior from continuing the current practice of exercising discretion to authorize higher percentage volume measurement uncertainty levels if appropriate technical and economic justifications have been provided.
