Abstract

On November 30, 2022, the Department of the Interior, through the Bureau of Land Management (BLM), published in the Federal Register a proposed rule entitled "Waste Prevention, Production Subject to Royalties, and Resource Conservation." This final rule aims to reduce the waste of natural gas from venting, flaring, and leaks during oil and gas production activities on Federal and Indian leases. The final rule also ensures that, when Federal or Indian gas is wasted, the public and Indian mineral owners are compensated for that wasted gas through royalty payments. This final rule will be codified in the Code of Federal Regulations and will replace the BLM's current requirements governing venting and flaring, which are more than four decades old.

II. Executive Summary

    On November 30, 2022, the Department of the Interior (DOI or 
``Department''), through the Bureau of Land Management (BLM), published 
in the Federal Register a proposed rule entitled, Waste Prevention, 
Production Subject to Royalties, and Resource Conservation. 87 FR 73588 
(Nov. 30, 2022). The BLM has considered the public comments received on 
the proposed rule to develop this final rule.
    This final rule aims to reduce the waste of natural gas from oil 
and gas leases administered by the BLM. This gas is lost during oil and 
gas exploration and production activities through venting, flaring, and 
leaks. Venting is the intentional release of gas into the atmosphere 
during operations, such as liquids unloading. Gas that is combusted in 
a controlled manner is flared gas. Leaks are the unintentional release 
of gas into the atmosphere from production equipment. Although some 
losses of gas may be unavoidable, Federal law requires that operators 
take reasonable steps to prevent the waste of gas through venting, 
flaring and leaks. The final rule describes the reasonable steps that 
operators of Federal and Indian oil and gas leases must take to avoid 
the waste of natural gas. The final rule also ensures that, when 
Federal or Indian gas is avoidably wasted, the public and Indian 
mineral owners are compensated for the wasted gas through royalty 
payments.
    The BLM administers a Federal onshore oil and gas leasing program 
pursuant to the requirements of various statutes, including the Mineral 
Leasing Act (MLA), the Federal Oil and Gas Royalty Management Act 
(FOGRMA), the Inflation Reduction Act of 2022 (IRA) Public Law 117-169, 
and the Federal Land Policy and Management Act (FLPMA). The MLA 
requires lessees to ``use all reasonable precautions to prevent waste 
of oil or gas developed in the land,'' \1\ and further requires oil and 
gas lessees to observe ``such rules . . . for the prevention of undue 
waste as may be prescribed by [the] Secretary . . . .'' \2\ Under 
FOGRMA, oil and gas lessees are liable for royalty payments on gas 
wasted from the lease site.\3\ In addition, as discussed further below, 
the IRA provides that, for leases issued after August 16, 2022, 
royalties are owed on all gas produced from Federal land, subject to 
certain exceptions for gas that is lost during emergency situations, 
used for the benefit of lease operations, or ``unavoidably lost.'' 
FLPMA authorizes the BLM to ``regulate'' the ``use, occupancy, and 
development'' of the public lands via ``published rules,'' while 
mandating that the Secretary, ``[i]n managing the public lands . . . 
shall, by regulation or otherwise, take any action necessary to prevent 
unnecessary or undue degradation of the lands.'' \4\ The BLM also 
regulates oil and gas operations on trust and restricted fee lands 
pursuant to the Indian Mineral Leasing Act, 25 U.S.C. 396a et seq.; the 
Act of March 3, 1909, 25 U.S.C. 396; and the Indian Mineral Development 
Act (IMDA), 25 U.S.C. 2101 et seq.

    In addition to managing the leasing and production of oil and gas 
from Federal lands, the BLM also oversees operations on many Indian and 
Tribal oil and gas leases pursuant to a delegation of authority from 
the Secretary of the Interior.\5\ The Secretary's management and 
regulation of Indian mineral interests carries with

it the duty to act as a trustee for the benefit of the Indian mineral 
owners.

    This final rule replaces the BLM's current requirements governing 
natural gas venting and flaring, which are contained in Notice to 
Lessees and Operators of Onshore Federal and Indian Oil and Gas Leases: 
Royalty or Compensation for Oil and Gas Lost (NTL-4A).\6\ NTL-4A was 
issued more than 40 years ago, and its policies and requirements are 
outdated. To begin, NTL-4A is ill-suited to address the large volume of 
flaring associated with the rapid development of unconventional 
``tight'' oil and gas resources that has occurred in recent years. In 
addition, NTL-4A does not account for technological and operational 
advancements that can reduce losses of gas from oil storage tanks and 
equipment leaks.
---------------------------------------------------------------------------

    \6\ 44 FR 76600 (Dec. 27, 1979).
---------------------------------------------------------------------------

    In 2016, the BLM issued a final rule replacing NTL-4A with new 
regulations intended to reduce the waste of gas from venting, flaring, 
and leaks.\7\ That rule was challenged in Federal court, and the BLM 
never fully implemented the rule due to the resulting litigation.\8\ In 
September 2018, the BLM issued a final rule effectively rescinding the 
2016 Rule, and that rule was itself challenged in court.\9\ Eventually, 
the United States District Court for the Northern District of 
California vacated the 2018 rescission of the 2016 Rule on various 
grounds, including what the Court determined was the rule's failure to 
meet the BLM's statutory mandate to prevent waste.\10\ The U.S. 
District Court for the District of Wyoming then vacated the 2016 Rule 
on the grounds that, among other things: (1) the MLA's ``delegation of 
authority does not allow and was not intended to authorize the 
enactment of rules justified primarily upon the ancillary benefit of a 
reduction in air pollution''; and (2) ``BLM acted arbitrarily and 
capriciously in failing to fully assess the impacts of the [2016 Rule] 
on marginal wells, failing to adequately explain and support the [2016 
Rule's] capture requirements, and failing to separately consider the 
domestic costs and benefits of the [2016 Rule].'' \11\ The result of 
these rulemakings and court decisions is that NTL-4A continues to 
govern venting and flaring from BLM-managed oil and gas leases.

---------------------------------------------------------------------------

    Based on the lessons of prior rulemakings and court decisions, the 
BLM concludes that this final rule will reduce the waste of natural gas 
through improved regulatory requirements pertaining to venting, 
flaring, and leaks, as well as improve upon NTL-4A in a variety of 
significant ways while eschewing elements of the 2016 Rule criticized 
by the District Court.
    In brief, the primary components of this final rule are as follows:
    <bullet> The final rule better implements the statutory requirement 
that the ``lessee will . . . use all reasonable precautions to prevent 
the waste of oil or gas developed in the land,'' \12\ consistent with 
the BLM's authority to issue rules implementing that statutory 
requirement.\13\ The final rule requires operators to take reasonable 
measures to prevent waste as conditions of approval of an Application 
for Permit to Drill (APD). Then, after an APD is approved, the BLM may 
order an operator to implement, within a reasonable amount of time, 
additional reasonable measures to prevent waste at ongoing exploration 
and production operations. Reasonable measures to prevent waste may 
reflect factors including, but not limited to, advances in technology 
and changes in industry practice.
---------------------------------------------------------------------------

    \12\ 30 U.S.C. 225.
    \13\ See 30 U.S.C. 187.
---------------------------------------------------------------------------

    <bullet> The final rule requires operators to submit either a Waste 
Minimization Plan (WMP) or a self-certification statement as one of 
five required attachments to their oil well applications for permit to 
drill.\14\ The WMP will provide the BLM with the following information: 
anticipated oil and associated-gas production and anticipated 3-year 
decline curves; certification that the operator has an executed, valid 
gas sales contract; and any other steps the operator commits to take to 
reduce or eliminate gas losses.
---------------------------------------------------------------------------

    \14\ See Sec.  3162.3-1(d).
---------------------------------------------------------------------------

    In lieu of a waste-minimization plan, the operator may choose to 
provide a self-certification statement. That statement would commit the 
operator to capturing 100 percent of the associated gas produced from 
an oil well and would obligate the operator to pay royalties on all 
lost gas except for gas lost through emergencies. With the addition of 
this new requirement to file a WMP or the described self-certification 
statement for oil-well APDs, operators must now provide five 
attachments with their completed Form 3160-3, including existing 
requirements for a drilling plan, a surface use plan of operations, and 
evidence of bond coverage. All five attachments must be 
administratively and technically complete before the BLM approves the 
APD. If the application is not complete, the BLM will defer action on 
the APD, and the operator will have an opportunity to address BLM-
identified deficiencies. In the case of a WMP or self-certification 
statement, the operator must address the identified deficiencies within 
2 years of receiving notification from the BLM of the deficiencies or 
the BLM may disapprove the application.
    <bullet> The final rule recognizes the IRA's provision that 
royalties are not owed on gas that is ``unavoidably lost''. The final 
rule clarifies which lost oil or gas will qualify as ``unavoidably 
lost'': lost oil or gas will qualify as ``unavoidably lost'' if, as 
stated in the final rule at Sec.  3179.41, the operator has taken 
reasonable steps to avoid waste; the operator has complied fully with 
applicable laws, lease terms, regulations, provisions of a previously 
approved operating plan, and other written orders of the BLM; and the 
loss is within the applicable time or volume limits. The final rule 
provides for several circumstances in which lost oil or gas will be 
considered ``unavoidably lost,'' including during well completions, 
production testing, and emergencies. The final rule also establishes a 
volumetric threshold based on oil production on royalty-free flaring 
due to pipeline capacity constraints, midstream processing failures, or 
other similar events that may prevent produced gas from being 
transported to market. The volumetric threshold is based on the total 
volume of gas flared in a month divided by the total net volume of oil 
produced in a month for each lease, unit PA, or CA. If an operator were 
to exceed the avoidable loss threshold, then royalties are due on the 
amount flared beyond the threshold.
    <bullet> The final rule includes specific affirmative obligations 
that operators must take to avoid wasting oil or gas. In particular:
    The final rule requires operators on Federal or Indian leases to 
maintain a leak detection and repair (LDAR) program designed to prevent 
the waste of Federal or Indian gas. An operator's LDAR program must 
provide for regular inspections of all oil and gas production, 
processing, treatment, storage, and measurement equipment on the lease 
site.
    The requirements of this final rule are explained in detail in 
sections III and IV that follow.
    As detailed in the Regulatory Impact Analysis (RIA) prepared for 
this final rule, the BLM estimates that this rule will have the 
following economic impacts:

[[Page 25380]]

    <bullet> Costs to industry of around $19.3 million per year 
(annualized at 7 percent);
    <bullet> Benefits to industry in recovered gas of $1.8 million per 
year (annualized at 7 percent);
    <bullet> Increases in royalty revenues from recovered and flared 
gas of $51 million per year; and
    <bullet> Ancillary effects society of $17.9 million per year from 
reduced greenhouse gas emissions (using a 3 percent discount rate).

III. Background

A. Waste of Natural Gas During the Development of Federal and Indian 
Oil and Gas Resources

    The BLM is responsible for managing more than 245 million surface 
acres of land and 700 million acres of subsurface mineral estate. The 
BLM maintains a program for leasing these lands for oil and gas 
development and regulates oil and gas production operations on Federal 
leases. While the BLM does not manage the leasing of Indian and Tribal 
lands for oil and gas production, the BLM does regulate oil and gas 
operations on many Indian and Tribal leases as part of its Tribal trust 
responsibilities.
    The BLM's onshore oil and gas management program is a significant 
contributor to the Nation's oil and gas production. Domestic production 
from 88,887 Federal onshore oil and gas wells \15\ accounts for 
approximately 8 percent of the Nation's natural gas supply and 9 
percent of its oil.\16\ In Fiscal Year (FY) 2021, operators produced 
473 million barrels of oil and 3.65 trillion cubic feet of natural gas 
from onshore Federal and Indian oil and gas leases. The production of 
this oil and gas generated more than $4.2 billion in royalties. 
Approximately $3.2 billion of these royalties were shared between the 
United States and the States in which the production occurred. 
Approximately $1 billion of these royalties went directly to Tribes and 
Indian allottees for production from Indian lands.\17\

---------------------------------------------------------------------------

    In recent years, the United States has experienced a significant 
increase in oil and natural gas production due to technological 
advances, such as hydraulic fracturing combined with directional 
drilling. This increase in production has been accompanied by a 
significant waste of natural gas through venting and flaring. During 
oil and gas operations it is sometimes necessary to vent gas (the 
intentional release of natural gas into the atmosphere) or to flare gas 
(the combustion of unsold gas). As the following graph illustrates, the 
amount of venting and flaring from Federal and Indian leases has 
increased dramatically from the 1990s to the 2010s, and the upward 
trend in flaring suggests that it will continue to be a problem. 
Between 1990 and 2000, the total venting and flaring reported by 
Federal and Indian onshore lessees averaged approximately 11 billion 
cubic feet (Bcf) per year. Between 2010 and 2020, in contrast, the 
total venting and flaring reported by Federal and Indian onshore 
lessees averaged approximately 44.2 Bcf per year.\18\
---------------------------------------------------------------------------

    \18\ The BLM analysis of ONRR Oil and Gas Operations Report part 
B (OGOR-B) data provided for 1990-2000 and 2010-2020. All venting 
and flaring data is nationwide and does not separate Federal and 
Indian data. For certain data points, separating Federal and Indian 
data would require a manual review of thousands of venting and 
flaring sundry notices since the BLM does not have a database that 
tracks this distinction.
[GRAPHIC] [TIFF OMITTED] TR10AP24.000

    Assuming a $3 per thousand cubic feet (Mcf) price of gas,\19\ the 
Federal and Indian gas that was vented and flared from 2010 to 2020 
would be valued at $1.46 billion. The BLM notes that vented and flared 
volumes have not

[[Page 25381]]

increased linearly with production: according to data maintained by the 
Office of Natural Resources Revenue (ONRR), the average volume of 
vented and flared gas as a percentage of total gas production was 0.42 
percent from 1990 to 2000; from 2010 to 2020, however, vented and 
flared gas averaged 1.07 percent of total gas production. This metric 
reflects a 157 percent increase in the waste of gas during oil and gas 
production from Federal and Indian lands. Furthermore, the average 
amount of vented and flared gas (in Mcf) per barrel (bbl) of oil 
production was 0.0815 Mcf/bbl from 1990 to 2000, while it rose to 
0.1642 Mcf/bbl from 2010 to 2020 \20\--a 102 percent increase in the 
waste of gas per barrel of oil produced. Together, these trends 
demonstrate that the requirements established by NTL-4A are ineffective 
at limiting the amount of gas that is vented or flared from Federal and 
Indian lands.
---------------------------------------------------------------------------

    \19\ The average annual Henry Hub spot price for natural gas 
from 2010 through 2020 was $3.19. U.S. Energy Information 
Administration (EIA), Henry Hub Natural Gas Spot Price, available at 
<a href="https://www.eia.gov/dnav/ng/hist/rngwhhda.htm">https://www.eia.gov/dnav/ng/hist/rngwhhda.htm</a>.
    \20\ In the proposed rule, the BLM erroneously stated that the 
average amount of vented and flared gas in thousands of cubic feet 
(Mcf) per barrel (bbl) of oil production was 0.8148 Mcf/bbl from 
1990 to 2000, which rose to 1.6418 Mcf/bbl from 2010 to 2020. The 
correct average amounts are 0.08148 Mcf/bbl of vented and flared gas 
from 1990 to 2000, which rose to 0.16418 Mcf/bbl from 2010 to 2020. 
The accompanying graph, which appeared in the proposed and final 
rules, is accurate and remains unchanged. Accordingly, the BLM is 
revising the cited average amounts to reflect the information 
provided in the accompanying graph.

BILLING CODE 4331-29-C
    Recent studies have identified three other major sources of gas 
losses during the oil and gas production process: emissions from 
natural-gas-activated pneumatic equipment, venting from oil storage 
tanks, and equipment leaks.\21\ The EPA estimates that, nationwide, 
36.2 Bcf of methane was emitted from pneumatic controllers and 4.9 Bcf 
of methane was emitted from equipment leaks at upstream oil and gas 
production sites in the United States in 2019.\22\ The BLM estimates 
that 13 Bcf of natural gas was lost from pneumatic devices on Federal 
and Indian lands in 2019. The BLM estimates that an additional 0.86 Bcf 
of gas was lost due to equipment leaks from Federal natural gas 
production operations not subject at the time to State or EPA (LDAR) 
requirements. Notably, leakage appears to be exacerbated in areas where 
there is insufficient infrastructure for natural gas gathering, 
processing, and transportation \23\--a known issue in basins such as 
the Permian and Bakken, where substantial BLM-managed oil and gas 
production occurs. Finally, the BLM estimates that 17.9 Bcf of natural 
gas was emitted from storage tanks on Federal and Indian lands in 2019. 
Losses from pneumatic equipment, leaks, and storage tanks would be 
valued at $53.7 million dollars (at $3/Mcf) in 2019.

---------------------------------------------------------------------------

    Apart from undue waste, excessive venting, flaring, and leaks by 
Federal oil and gas lessees also impose three additional harms. First, 
vented or leaked gas wastes valuable publicly or Indian owned resources 
that could be put to productive use, and deprives American taxpayers, 
Tribes, and States of substantial royalty revenues. Second, the wasted 
gas may harm local communities and surrounding areas through visual and 
noise impacts from flaring. And third, vented or leaked gas also 
contributes to climate change, because the primary constituent of 
natural gas is methane, an especially powerful greenhouse gas, with 
climate impacts roughly 28 to 36 times those of carbon dioxide 
(CO<INF>2</INF>), if measured over a 100-year period, or 84 times those 
of CO<INF>2</INF> if measured over a 20-year period.\24\ Thus, 
regulatory measures that encourage operators to conserve gas and avoid 
waste could, as a purely incidental matter, have ancillary effects on 
public health and the environment.\25\
---------------------------------------------------------------------------

    \24\ See Intergovernmental Panel on Climate Change, Climate 
Change 2013: The Physical Science Basis, Chapter 8, Anthropogenic 
and Natural Radiative Forcing, at 714 (Table 8.7), available at 
<a href="https://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter08_FINAL.pdf">https://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter08_FINAL.pdf</a>.
    \25\ The BLM notes that the BLM did not rely on such ancillary 
effects in developing this final rule. Rather, with the exception of 
the safety provisions in Sec.  3179.50 (which also promotes worker 
health), the requirements of this final rule are independently 
justified as reasonable measures to prevent waste that would be 
expected, regardless of ancillary effects on public health or the 
environment.
---------------------------------------------------------------------------

    Both the MLA and IRA distinguish an avoidable loss from an 
unavoidable loss. Indeed, some amount of venting and flaring is 
unavoidable and expected to occur during oil and gas exploration and 
production operations. For example, an operator may need to flare gas 
on a short-term basis as part of drilling operations, well completion, 
or production testing, among other situations. Longer-term flaring may 
occur in exceptional circumstances, which might include the drilling of 
and production from an exploratory well in a new field, where gas 
pipelines have not yet been built due to a lack of information 
regarding expected gas production.\26\ In some fields, the overall 
quantity of gas produced may be so small that the development of gas-
pipeline infrastructure may not be economically justified.
---------------------------------------------------------------------------

    \26\ The BLM notes that, even in such exceptional circumstances, 
operators should be expected to take measures to avoid excessive 
flaring and this proposed rule would place limitations on royalty-
free flaring from exploratory wells.
---------------------------------------------------------------------------

    Although some venting or flaring may be unavoidable (and thus not 
waste) under some circumstances, operators have an affirmative 
obligation under Federal law to use reasonable precautions to prevent 
the waste of oil or gas developed from a lease. As other technologies 
and practices on oil and gas operations have evolved (as evidenced by 
changes in State and Federal regulations, and in industry best 
practices), so too measures that are considered reasonable to prevent 
waste should progress over time with advances in technology and changes 
in industry practice.
    Further, operators' immediate economic interests may not always be 
served by minimizing the loss of natural gas, and BLM regulation is 
necessary to discourage operators from venting or flaring more gas than 
is operationally necessary. A prime example is the flaring of oil-well 
gas due to pipeline capacity constraints. Oil wells in certain fields 
are known to produce relatively large volumes of associated natural 
gas. Accordingly, natural-gas-capture infrastructure--including 
pipelines--has been built out in those fields, and the BLM expects 
operators to sell the associated gas they produce. However, it is not 
uncommon for the rate of oil-well development to outpace the capacity 
of the related gas-capture infrastructure. When the existing gas-
capture infrastructure is overwhelmed, an operator is faced with a 
choice: flare the associated gas in order to continue oil production 
unabated or curtail oil production in order to conserve the associated 
gas. Absent clear requirements in NTL-4A as to whether a specific 
operational circumstance is an avoidable or unavoidable loss, an 
operator might conclude that the BLM would not make any avoidable loss 
determination if the operator were to flare, and thus waste associated 
gas to continue oil production--maximizing the operators' short-term 
profits by providing immediate revenue from oil production, even 
accounting for the loss of gas revenue. But the latter course of action 
may often best serve the public's interest by maximizing overall energy 
production (considering both production streams rather than producing 
oil and flaring gas) and royalty revenues.
    Likewise, maximizing the recovery of gas by regularly inspecting 
for leaks may not always maximize the operator's profits. It is in 
these circumstances--where an operator's interest in maximizing short-
term profits diverges from the public's interest in maximizing resource 
recovery--that BLM regulation is necessary and appropriate to ensure 
that operators take reasonable measures to prevent waste, as required 
by statute.

B. Legal Authority

    Pursuant to a delegation of Secretarial authority, the BLM is 
authorized to regulate oil and gas exploration and production 
activities on Federal and Indian lands under a variety of statutes, 
including the MLA, the Mineral Leasing Act for Acquired Lands, the IRA, 
FOGRMA, the FLPMA, the Indian Mineral Leasing Act of 1938, the IMDA, 
and the Act of March 3, 1909.\27\ These statutes authorize the 
Secretary of the Interior to promulgate such rules and regulations as 
may be necessary to carry out the statutes' various purposes.\28\

7. Authority Regarding the Waste of Natural Gas
    The MLA rests on the fundamental principle that the public should 
benefit from mineral production on public lands.\29\ An important means 
of ensuring that the public benefits from mineral production on public 
lands is minimizing and deterring the waste of oil and gas produced 
from the Federal mineral estate. To this end, the MLA requires that all 
oil and gas lessees be subject to the condition that lessees ``use all 
reasonable precautions to prevent waste of oil or gas developed in the 
land . . . .'' \30\ The MLA requires oil and gas lessees to exercise 
``reasonable diligence, skill, and care'' in their operations and to 
observe ``such rules . . . for the prevention of undue waste as may be 
prescribed by [the] Secretary.'' \31\ Lessees are not only responsible 
for taking measures to prevent waste, but also for making royalty 
payments on wasted oil and gas when waste occurs, in accordance with 
the MLA's assessment of royalties on all ``production removed or sold 
from the lease.'' \32\ Furthermore, FOGRMA expressly makes lessees 
``liable for royalty payments on oil or gas lost or wasted from a lease 
site when such loss or waste is due to negligence on the part of the 
operator of the lease, or due to the failure to comply with any rule or 
regulation, order or citation issued under [FOGRMA] or any mineral 
leasing law.'' \33\
---------------------------------------------------------------------------

    \29\ See, e.g., California Co. v. Udall, 296 F.2d 384, 388 (D.C. 
Cir. 1961) (noting that the MLA was ``intended to promote wise 
development of . . . natural resources and to obtain for the public 
a reasonable financial return on assets that `belong' to the 
public'').

---------------------------------------------------------------------------

    In addition, on August 16, 2022, President Biden signed the IRA 
into law. Section 50263 of the IRA, which is entitled ``Royalties on 
All Extracted Methane,'' provides that, for leases issued after August 
16, 2022, royalties are owed on all gas produced from Federal land, 
including gas that is consumed or lost by venting, flaring, or 
negligent releases through any equipment during upstream operations. 
This section further provides three exceptions to the general 
obligation to pay royalties on produced gas, namely on: ``(1) gas 
vented or flared for not longer than 48 hours in an emergency situation 
that poses a danger to human health, safety, or the environment; (2) 
gas used or consumed within the area of the lease, unit, or 
communitized area for the benefit of the lease, unit, or communitized 
area; or, (3) gas that is unavoidably lost.'' \34\
---------------------------------------------------------------------------

    \34\ 30 U.S.C. 1727.
---------------------------------------------------------------------------

    The BLM's authority to regulate the waste of Federal oil and gas is 
not limited to operations that occur on Federal lands, but also extends 
to operations on non-Federal lands where Federal oil and gas is 
produced under a unit or communitization agreement (CA). ``For the 
purpose of more properly conserving the natural resources of any oil or 
gas pool, field, or like area,'' the MLA authorizes lessees to operate 
their leases under a cooperative or unit plan of development and 
operation if the Secretary of the Interior determines such an 
arrangement to be necessary or advisable in the public interest.\35\ 
The Secretary is authorized, with the consent of the lessees involved, 
to establish or alter drilling, producing, and royalty requirements and 
to make such regulations with respect to the leases under a cooperative 
or unit plan.\36\ The MLA states that a cooperative or unit plan of 
development may contain a provision authorizing the Secretary to 
regulate the rate of development and the rate of production.\37\ 
Accordingly, the BLM's standard form unit agreement provides that the 
BLM may regulate the quantity and rate of production in the interest of 
conservation.\38\ The BLM's standard form CA provides that the BLM 
``shall have the right of supervision over all fee and state mineral 
operations within the communitized area to the extent necessary to 
monitor production and measurement, and to assure that no avoidable 
loss of hydrocarbons occurs . . . .'' \39\ As noted earlier, FOGRMA 
authorizes the BLM to assess royalties on gas lost or wasted from a 
``lease site.'' The term ``lease site'' is broadly defined in FOGRMA as 
any lands or submerged lands, including the surface of a severed 
mineral estate, on which exploration for, or extraction or removal of, 
oil or gas is authorized pursuant to a lease.\40\ The BLM maintains the 
authority to regulate the waste of Federal minerals from operations on 
those lands by requiring royalty payments and setting appropriate rates 
of development and production.\41\

definition of `lease site' necessarily includes any lands, including 
privately-owned lands, on which [production] of oil or gas is 
occurring pursuant to a communitization agreement''). Additionally, 
FOGRMA defines ``oil and gas'' broadly to mean ``any oil or gas 
originating from, or allocated to, the Outer Continental Shelf, 
Federal, or Indian lands.'' 30 U.S.C. 1702(9) (emphasis added).
    \41\ This conclusion is consistent with the assessment of the 
BLM's authority expressed by the court that vacated the 2016 Waste 
Prevention Rule. See Wyoming 493 F. Supp. 3d at 1081-85.
---------------------------------------------------------------------------

2. Authority Regarding Environmental Impacts to the Public Lands
    In addition to ensuring that the public receives a pecuniary 
benefit from oil and gas production from public lands, the BLM is also 
tasked with regulating the physical impacts of oil and gas development 
on public lands. The MLA directs the Secretary to ``regulate all 
surface-disturbing activities conducted pursuant to any lease'' and to 
``determine reclamation and other actions as required in the interest 
of conservation of surface resources.'' \42\
---------------------------------------------------------------------------

    \42\ 30 U.S.C. 226(g).
---------------------------------------------------------------------------

    The MLA requires oil and gas leases to include provisions ``for the 
protection of the interests of the United States . . . and for the 
safeguarding of the public welfare,'' including lease terms for 
purposes other than safeguarding the public resource of oil and 
gas.\43\ The Secretary may suspend lease operations ``in the interest 
of conservation of natural resources,'' a phrase that encompasses not 
just conservation of mineral deposits, but also preventing 
environmental harm.\44\ The MLA additionally requires oil and gas 
leases to contain ``a provision that such rules for the safety and 
welfare of the miners

[[Page 25384]]

. . . as may be prescribed by the Secretary shall be observed.'' \45\ 
Accordingly, the Department's regulations governing oil and gas 
operations on the public lands have long required operators to conduct 
operations in a manner that is protective of natural resources, 
environmental quality, and the health and safety of workers.\46\
---------------------------------------------------------------------------

    \43\ See Natural Resources Defense Council, Inc. v. Berklund, 
458 F. Supp. 925, 936 n.17 (D.D.C. 1978). The BLM acknowledges that 
the court that vacated the 2016 Waste Prevention Rule stated that 
``it is not a reasonable interpretation of BLM's general authority 
under the MLA to `safeguard[ ] the public welfare' as empowering the 
agency to regulate air emissions, particularly when Congress 
expressly delegated such authority to the EPA under the [Clean Air 
Act].'' Wyoming 493 F. Supp. 3d at 1067. The BLM further notes that 
the court that vacated the BLM's rescission of the 2016 Waste 
Prevention Rule found that the rescission failed to satisfy the 
BLM's ``statutory obligation'' to ``safeguard[ ] the public 
welfare,'' and stated that the MLA's ``public welfare'' provision 
supports the BLM's consideration of air emissions in promulgating 
its waste prevention regulations. See California v. Bernhardt, 472 
F. Supp. 3d 573, 616 (N.D. Cal. 2020). The BLM need not elaborate on 
the meaning of the MLA's ``public welfare'' provision in this 
rulemaking, as the BLM is proposing requirements that are 
independently justified as waste prevention measures and are not for 
environmental purposes. The one exception is Sec.  3179.50, which 
does serve an environmental purpose, but is an exercise of the 
Secretary's authority to prescribe ``rules for the safety and 
welfare of the miners'' under 30 U.S.C. 187.

    FLPMA authorizes the BLM to ``regulate'' the ``use, occupancy, and 
development'' of the public lands via ``published rules.'' \47\ FLPMA 
also mandates that the Secretary, ``[i]n managing the public lands . . 
. shall, by regulation or otherwise, take any action necessary to 
prevent unnecessary or undue degradation of the lands.'' \48\ In 
addition, section 102 of FLPMA declares a policy that the BLM should 
both protect the environment, as stated in paragraph 102(a)(8), and 
manage the land in such a manner as to provide for ``domestic sources 
of minerals'' and other resources, as stated in paragraph 
102(a)(12).\49\ With respect to protecting the environment, paragraph 
102(a)(8) states the policy of the United States that lands be managed 
to ``protect the quality of scientific, scenic, historical, ecological, 
environmental, air and atmospheric, water resources, and archeological 
values . . . .'' \50\

``Multiple use'' also requires resources to be managed in a 
``harmonious and coordinated'' manner ``without permanent impairment to 
the productivity of the land and the quality of the environment . . . 
.'' \53\ Significantly, FLPMA directs the Secretary to consider ``the 
relative values of the resources and not necessarily . . . the 
combination of uses that will give the greatest economic return or the 
greatest unit output.'' \54\

    The Secretary's management and regulation of Indian mineral 
interests carries with it the duty to act as a trustee for the benefit 
of the Indian mineral owners.\55\ Congress has directed the Secretary 
to ``aggressively carry out [her] trust responsibility in the 
administration of Indian oil and gas.'' \56\ In furtherance of her 
trust obligations, the Secretary has delegated regulatory authority for 
administering operations on Indian oil and gas leases to the BLM,\57\ 
which has developed specialized expertise through regulating the 
production of oil and gas from public lands administered by the 
Department. In choosing from among reasonable regulatory alternatives 
for Indian mineral development, the BLM is obligated to adopt the 
alternative that is in the best interest of the Tribe and individual 
Indian mineral owners.\58\ What is in the best interest of the Tribe 
and individual Indian mineral owners is determined by a consideration 
of all relevant factors, including economic considerations as well as 
potential environmental and social effects.\59\

C. Regulatory History

    The BLM has a long history of regulating venting and flaring from 
onshore oil and gas operations. This section summarizes the BLM's 
historic practices, as well as the BLM's experience in two recent 
rulemakings related to venting and flaring.
8. Early Regulation of Surface Waste of Gas
    The Department of the Interior has maintained regulations 
addressing the waste of gas through venting and flaring from onshore 
oil and gas leases since 1938. At that time, the Department's 
regulations required the United States to be compensated ``at full 
value'' for ``all gas wasted by blowing, release, escape into the air, 
or otherwise,'' except where such disposal was authorized under the 
laws of the United States and the State in which it occurred.\60\ The 
regulations further provided that the production of oil or gas from the 
lease was to be restricted to such amounts as could be put to 
beneficial use and that, in order to avoid the excessive production of 
oil or gas, the Secretary could limit the rate of production based on 
the market demand for oil or the market demand for gas.\61\
---------------------------------------------------------------------------

    \60\ 30 CFR 221.5(h) (1938).
    \61\ Id. 221.27.
---------------------------------------------------------------------------

    By 1942, the Department's regulations contained a definition of 
``waste of oil or gas.'' This definition included the ``physical waste 
of oil or gas,'' which was defined as ``the loss or destruction of oil 
or gas after recovery thereof such as to prevent proper utilization and 
beneficial use thereof, and the loss of oil or gas prior to recovery 
thereof by isolation or entrapment, by migration, by premature release 
of natural gas from solution in oil, or in any other manner such as to 
render impracticable the recovery of such oil or gas.'' \62\ The 
regulations stated that a lessee was ``obligated to prevent the waste 
of oil or gas'' and, in order to avoid the physical waste of gas, the 
lessee was required to ``consume it beneficially or market it or return 
it to the productive formation.'' \63\ The regulations stated that 
``unavoidably lost'' gas was not subject to royalty, though the 
regulations did not define ``unavoidably lost.'' \64\

    \63\ Id. 221.35.
    \64\ Id. 221.44.
---------------------------------------------------------------------------

    In 1974, the Secretary issued NTL-4, which established the 
following policy for royalties on gas production: Gas production 
subject to royalty shall include: (1) that gas (both dry and casing-
head) which is produced and sold either on a lease basis or that which 
is allocated to a lease under the terms of an approved communitization 
or unitization agreement; (2) that gas which is vented or flared in 
well tests (drill-stem, completion, or production) on a lease, 
communitized tract, or unitized area; and, (3) that gas which is 
otherwise vented or flared on a lease, communitized tract, or unitized 
area with the prior written authorization of the Area Oil and Gas 
Supervisor (Supervisor).\65\
---------------------------------------------------------------------------

    \65\ See 44 FR 76600 (Dec. 27, 1979).
---------------------------------------------------------------------------

    NTL-4 thus effectively required onshore oil and gas lessees to pay 
royalties on all gas produced, including gas that was unavoidably lost 
or used for production purposes. Various oil and gas companies sought 
judicial review of NTL-4. In 1978, the U.S. District Court for the 
District of Wyoming overturned NTL-4, holding that the MLA does not 
authorize the collection of royalties on gas production

[[Page 25385]]

that is unavoidably lost or used in lease operations.\66\

2. NTL-4A
    From January 1980 to January 2017, the Department of the Interior's 
instructions governing the venting and flaring of gas from onshore oil 
and gas leases were contained in ``Notice to Lessees and Operators of 
Onshore Federal and Indian Oil and Gas Leases: Royalty or Compensation 
for Oil and Gas Lost'' (``NTL-4A'').\67\ NTL-4A was issued by the U.S. 
Geological Survey (USGS), which was the Interior bureau tasked with 
oversight of Federal onshore oil and gas production at the time.
---------------------------------------------------------------------------

    \67\ 44 FR 76600 (Dec. 27, 1979).
---------------------------------------------------------------------------

    Under NTL-4A, operators were required to pay royalties on 
``avoidably lost'' gas--i.e., gas lost due to the operator's 
negligence, failure to take reasonable precautions to prevent or 
control the loss, or failure to comply with lease terms, regulations, 
or BLM orders. NTL-4A expressly authorized royalty-free venting and 
flaring ``on a short-term basis'' during emergencies, well purging and 
evaluation tests, initial production tests, and routine and special 
well tests. NTL-4A prohibited the flaring of gas from gas wells under 
any other circumstances. For gas produced from oil wells, however, NTL-
4A authorized (but did not mandate) the BLM to approve flaring where 
conservation of the gas was not ``economically justified'' because it 
would ``lead to the premature abandonment of recoverable oil reserves 
and ultimately to a greater loss of equivalent energy than would be 
recovered if the venting or flaring were permitted to continue . . . 
.'' \68\ NTL-4A stated that, ``when evaluating the feasibility of 
requiring conservation of the gas, the total leasehold production, 
including oil and gas, as well as the economics of a field-wide plan,'' 
must be considered. Finally, under NTL-4A, the loss of gas vapors from 
storage tanks was considered ``unavoidably lost,'' unless the BLM 
``determine[d] that the recovery of such vapors would be warranted . . 
. .'' \69\

---------------------------------------------------------------------------

    Soon after issuing NTL-4A, the USGS issued guidelines and 
procedures for implementing NTL-4A, which were published in the 
Conservation Division Manual (CDM) Part 644, Chapter 5.\70\ Among other 
things, the CDM provided guidance regarding applications to flare oil-
well gas. Specifically, the CDM provided guidance for responding to a 
lessee's contention ``that reserves of casinghead gas are inadequate to 
support the installation of facilities for gas collection and sale . . 
. .'' \71\ The CDM explained that, ``[f]rom an economic basis, all 
leasehold production must be considered; the major concern is 
profitable operation of the lease, not just profitable disposition of 
the gas.'' \72\ The CDM further explained that the ``economics of 
conserving gas must be on a field-wide basis, and the Supervisor must 
consider the feasibility of a joint operation between all other 
lessees/operators in the field or area.'' \73\ Thus, the economic 
standard for obtaining approval to flare oil-well gas under NTL-4A was 
on its face a demanding one. The fact that the capture and sale of oil-
well gas from an individual lease would not pay for itself was not 
sufficient to justify royalty-free flaring of the gas.

---------------------------------------------------------------------------

    The CDM also provided guidance for venting and flaring situations 
involving both Federal and non-Federal lands. In such cases, the BLM 
was directed to contact the appropriate State agency to work jointly 
for optimum gas conservation. However, where such a cooperative effort 
was not possible, the BLM was directed to ``proceed unilaterally to 
take action to prevent unnecessary venting or flaring from Federal 
lands.''
    Under the plain terms of NTL-4A, flaring without prior approval 
(outside of the short-term circumstances specified in Sections II and 
III of NTL-4A) constituted a royalty-bearing loss of gas, regardless of 
the economic circumstances. The BLM originally applied NTL-4A to that 
effect, and this practice was upheld by the Interior Board of Land 
Appeals. See Lomax Exploration Co., 105 IBLA 1 (1988). However, the BLM 
changed this policy in Instruction Memorandum No. 87-652 (Aug. 17, 
1987), which required the BLM to provide an operator with 
an207pportuneity to demonstrate, after the fact, that capturing the gas 
was not economically justified. See Ladd Petroleum Corp., 107 IBLA 5 
(1989).
    Even so, the number of applications for royalty-free flaring 
received by the BLM increased dramatically between 2005 and 2016: in 
2005, the BLM received just 75 applications to vent or flare gas, while 
in 2015 it received 2,901 applications.\74\ The following table shows 
the number of applications to vent or flare gas received by the BLM 
through 2021, but it does not reflect when the venting or flaring 
occurred.\75\
---------------------------------------------------------------------------

    \74\ Following publication of the proposed rule, the BLM re-
queried the Automated Fluid Minerals Support System (AFMSS) to 
obtain the number of venting and flaring sundry notices in the 
database. The number of sundry notices has been updated in the final 
rule to reflect the updated query.
    \75\ The BLM applies the venting and flaring rule that was in 
effect at the time the flaring occurred, not when the application 
was received, which may be later in time than the flaring, even 
years later. See, e.g., Ladd Petroleum Corp., 107 IBLA 5 (1989). The 
application, therefore, does not provide for straightforward 
comparison of the effects of regulatory changes, particularly given 
recent court orders setting aside the BLM's rules in this sphere.

    Both the 2016 Waste Prevention Rule and the 2018 Revision Rule 
would have dispensed with case-by-case flaring approvals, but because 
those rules were both struck down, post-2016 flaring application data 
does not provide a useful comparison between the 2016 Waste Prevention 
Rule and NTL-4A. In addition, there is no useful comparison because the 
2016 Waste Prevention Rule was never in effect and the 2018 revision 
rule was in effect for less than 2 years. Most of the applications to 
flare royalty-free were submitted to the field offices in New Mexico, 
Montana, and the Dakotas, which oversee Federal and Indian mineral 
interests in unconventional plays where oil production is accompanied 
by large volumes of associated gas. Notably, the vast majority of these 
applications involved wells that were connected to a gas pipeline but 
flared due to pipeline capacity constraints.
3. 2016 Waste Prevention Rule
    On November 18, 2016, the BLM issued a final rule intended to 
reduce the waste of Federal and Indian gas through venting, flaring, 
and leaks (``2016 Waste Prevention Rule'').\76\ The 2016 Waste 
Prevention Rule replaced NTL-4A and became effective on January 17, 
2017. The BLM's development of the 2016 Waste Prevention Rule was 
prompted by a

[[Page 25386]]

combination of factors, including the substantial increase in flaring 
over the previous decade, the growing number of applications to vent or 
flare royalty-free, new information regarding the quantities of gas 
lost through venting and leaks, and concerns expressed by oversight 
entities such as the U.S. Government Accountability Office (GAO).\77\

Increase Royalty Payments and Reduce Greenhouse Gases'' (Oct. 2010); 
GAO, ``OIL AND GAS--Interior Could Do More to Account for and Manage 
Natural Gas Emissions'' (July 2016).
---------------------------------------------------------------------------

    The 2016 Waste Prevention Rule applied to all onshore Federal and 
Indian oil and gas leases, units, and communitized areas. The key 
components of the 2016 Waste Prevention Rule were:
    <bullet> A requirement that APDs be accompanied by a WMP that would 
detail anticipated gas production and opportunities to conserve the 
gas;
    <bullet> A provision specifying the various circumstances under 
which a loss of oil or gas would be ``avoidably lost'' and therefore 
royalty-bearing;
    <bullet> A requirement that operators capture (rather than flare) a 
certain percentage of the gas they produce;
    <bullet> Equipment requirements for pneumatic controllers, 
pneumatic diaphragm pumps, and storage vessels (tanks); and
    <bullet> LDAR provisions requiring semiannual lease site 
inspections, the use of specified instruments and methods, and 
recordkeeping and reporting.
    The rule's ``capture percentage'' requirements were intended to 
address the routine flaring of gas from oil wells. The rule required an 
operator to capture, rather than flare, a certain percentage of the gas 
produced from the operator's ``development oil wells.'' The required 
capture percentage would increase over a 10-year period, starting at 85 
percent in 2018 and ultimately reaching 98 percent in 2026. Gas flared 
in excess of the capture requirements would be royalty bearing.
    In the 2016 Waste Prevention Rule, the BLM recognized that the EPA 
had promulgated emissions limitations for pneumatic equipment and 
storage tanks as well as LDAR requirements for new and modified sources 
in the oil and gas production sector pursuant to its authority under 
the Clean Air Act (CAA). The BLM further recognized that those EPA 
requirements would have the effect of reducing the waste of gas from 
leases subject to those requirements. In order to avoid unnecessary 
duplication or conflict between the BLM and EPA regulations, the 2016 
Waste Prevention Rule allowed for operators to comply with the 
analogous EPA regulations as an alternative means of compliance with 
BLM's requirements.\78\

    \78\ See 81 FR 83008, 83018-19, 83085-89 (Nov. 18, 2016).
---------------------------------------------------------------------------

    The capture percentage, pneumatic equipment, storage tanks, and 
LDAR requirements of the 2016 Rule were each subject to phase-in 
periods, and the rule allowed operators to obtain exemptions or reduced 
requirements where compliance would ``cause the operator to cease 
production and abandon significant recoverable oil reserves under the 
lease.'' \79\ The BLM's RIA for the 2016 Waste Prevention rule 
estimated that the rule would impose costs of between $110 million and 
$275 million per year, while generating benefits of between $20 million 
and $157 million per year worth of additional gas captured and between 
$189 million and $247 million per year in quantified social benefits 
(in the form of forgone methane emissions).\80\

    Certain States and operators filed petitions for judicial review of 
the Waste Prevention Rule in the U.S. District Court for the District 
of Wyoming.\81\ Following the change in Administration in January 2017, 
the litigation was effectively paused in response to the BLM's 
administrative actions to suspend the rule. After those actions were 
invalidated by a different court,\82\ the Wyoming court stayed 
implementation of the capture percentage, pneumatic equipment, storage 
tank, and LDAR requirements, and stayed the litigation pending 
finalization of the BLM's voluntary revision of the 2016 Waste 
Prevention Rule.

Sierra Club v. Zinke, No. 3:17-CV-03885-EDL (N.D. Cal.). On June 15, 
2017, the BLM announced that it would postpone the January 17, 2018, 
compliance dates to phase-in certain parts of the 2016 Waste 
Prevention Rule. Wyoming at 1053. Several Intervenors-Respondents 
from the Wyoming litigation, as well as the Attorney Generals from 
the States of California and New Mexico challenged the BLM's 2017 
postponement decision in the aforementioned cases in the Northern 
District of California. Id. at 1053-54. This California district 
court held that the BLM's 2017 postponement notice was invalid, 
thereby resulting in the reinstatement of the phase-in dates for 
certain parts of the 2016 Waste Prevention Rule. Id. at 1054.
---------------------------------------------------------------------------

    4. 2018 Revision of Waste Prevention Rule
    On September 28, 2018, the BLM issued a final rule substantially 
revising the 2016 Waste Prevention Rule (``2018 Revision Rule'').\83\ 
In the 2018 Revision Rule, the BLM rescinded the WMP, gas capture 
percentage, pneumatic equipment, storage tank, and LDAR requirements of 
the 2016 Waste Prevention Rule. The BLM also revised the remaining 
provisions of the rule to largely reflect the language of NTL-4A. 
Finally, the BLM established a new policy of deferring to State 
regulations for determining when the routine flaring of oil-well gas is 
royalty-free.
---------------------------------------------------------------------------

    \83\ 83 FR 49184 (Sept. 28, 2018).
---------------------------------------------------------------------------

    In the 2018 Revision Rule, the BLM concluded that the 2016 Waste 
Prevention Rule exceeded the BLM's statutory authority by imposing 
requirements with compliance costs that exceed the value of the gas 
that would be conserved, thus violating the non-statutory ``prudent 
operator'' standard that some believed to have been implicitly 
incorporated into the MLA when it was adopted in 1920. The BLM also 
stated that the 2016 Waste Prevention Rule created a risk of premature 
shut-ins of marginal wells, reasoning that the compliance costs 
associated with the 2016 Waste Prevention Rule would represent a 
significant proportion of a marginal well's revenue. Contrary to what 
the BLM had found in 2016, the BLM stated in the 2018 Revision Rule 
that existing State flaring regulations provided sufficient assurance 
against excessive flaring.
    The RIA for the 2018 Revision Rule found that the economic benefits 
of the 2018 Revision Rule (i.e., reduced compliance costs) would 
significantly outweigh its economic costs (i.e., forgone gas production 
and additional methane emissions).\84\ This result was based in large 
part on the use of a narrowly defined ``domestic'' social cost of 
methane metric. That metric purported to capture domestic methane 
costs. However, because it focused on impacts within U.S. borders, it 
underestimated the full benefits of GHG mitigation accruing to U.S. 
citizens and residents and thus drastically reduced the monetized 
climate benefits of the 2016 Waste Prevention Rule relative to

[[Page 25387]]

what had been estimated in the RIA for the 2016 Waste Prevention 
Rule.\85\

5. Judicial Review of the Revision Rule
    In September 2018, a coalition of organizations and the States of 
California and New Mexico filed lawsuits challenging the 2018 Revision 
Rule in the U.S. District Court for the Northern District of 
California. On July 15, 2020, the district court ruled in favor of the 
plaintiffs. California v. Bernhardt, 472 F. Supp. 3d 573 (N.D. Cal. 
2020). The court found that:
    <bullet> The BLM's interpretation of its statutory authority in the 
2018 Revision Rule was unjustifiably limited, failed to require lessees 
to use all reasonable precautions to prevent waste, and failed to meet 
the BLM's statutory mandate to protect the public welfare;
    <bullet> The BLM's decision to defer to State flaring regulations 
was not supported by sufficient analysis or record evidence;
    <bullet> The record did not support the BLM's claims that the 2016 
Waste Prevention Rule posed excessive regulatory burdens and that its 
costs outweighed its benefits; and
    <bullet> The BLM's cost-benefit analysis underlying the rule was 
flawed for a variety of reasons, including that the use of a 
``domestic'' social cost of methane was unreasonable and not based on 
the best available science.
    The court ordered that the 2018 Revision Rule be vacated in its 
entirety.\86\
---------------------------------------------------------------------------

    \86\ However, the court stayed vacatur until October 13, 2020.
---------------------------------------------------------------------------

6. Judicial Review of the 2016 Waste Prevention Rule
    Following the decision in California v. Bernhardt, the Wyoming 
court lifted the stay on the litigation over the 2016 Waste Prevention 
Rule. In the briefing, the Department of the Interior confessed error 
on the grounds that the BLM exceeded its statutory authority and was 
``arbitrary and capricious'' in promulgating the rule. In October 2020, 
the district court ruled in favor of the plaintiffs, finding that the 
BLM had exceeded its statutory authority and had been arbitrary and 
capricious in promulgating the 2016 Waste Prevention Rule. Wyoming v. 
U.S. Dep't of the Interior, 493 F. Supp. 3d 1046 (D. Wyo. 2020). 
Specifically, the court found that the 2016 Waste Prevention Rule was 
essentially an air quality regulation and that the BLM had usurped the 
authority to regulate air emissions that Congress had granted to EPA 
and the States in the CAA. The court found that the rule was not 
independently justified as a waste-prevention measure under the MLA. 
Rather, in the court's view, the record reflected that the BLM's 
primary concern was regulating methane emissions from existing oil and 
gas sources. The court faulted the BLM's rulemaking for imposing 
requirements beyond what could be expected of a ``prudent operator'' 
that develops the lease for the mutual profit of lessee and lessor. 
Finally, the court faulted the BLM for applying air quality 
regulations--as opposed to waste-prevention regulations--to unit and CA 
operations on non-Federal lands. The court ordered that the 2016 Waste 
Prevention Rule be vacated, thereby reinstating NTL-4A as the BLM's 
standard for managing venting and flaring from Federal oil and gas 
leases.
7. The Inflation Reduction Act
    On August 16, 2022, President Biden signed the IRA into law.\87\ 
The IRA contains a suite of provisions addressing onshore and offshore 
oil and gas development under Federal leases. For example, section 
50265, inter alia, requires the Department to maintain a certain level 
of onshore oil and gas leasing activity as a prerequisite to approving 
renewable energy rights-of-way on Federal lands. Importantly, that 
provision of the IRA is accompanied by other provisions that serve to 
ensure that lessees pay fair and appropriate compensation to the 
Federal Government in exchange for the opportunity to conduct their 
industrial activities under Federal leases.
---------------------------------------------------------------------------

    \87\ Public Law 117-169.
---------------------------------------------------------------------------

    One such provision of the Act is section 50263, which is entitled, 
``Royalties on All Extracted Methane.'' \88\ Consistent with the MLA's 
assessment of royalties on all gas ``removed or sold from the lease'' 
\89\ and FOGRMA's requirement that lessees pay royalties on lost or 
wasted gas,\90\ section 50263 of the IRA provides that, for leases 
issued after the date of enactment of the Act, royalties are owed on 
all gas produced from Federal land, including gas that is consumed or 
lost by venting, flaring, or negligent releases through any equipment 
during upstream operations. Section 50263 further provides three 
exceptions to the general obligation to pay royalties on produced gas, 
namely: (1) gas that is vented or flared for not longer than 48 hours 
in an emergency situation that poses a danger to human health, safety, 
or the environment; (2) gas used or consumed within a lease, unit, or 
communitized area for the benefit of the lease, unit, or communitized 
area; and, (3) gas that is unavoidably lost.\91\
---------------------------------------------------------------------------

    \88\ 30 U.S.C. 1727.
    \89\ 30 U.S.C. 226(b).
    \90\ 30 U.S.C. 1756.
    \91\ 30 U.S.C. 1727.
---------------------------------------------------------------------------

    The BLM has for decades assessed royalties on upstream production 
and has exempted from royalties gas lost in emergency situations, 
``beneficial use'' gas, and ``unavoidably lost'' gas. IRA section 50263 
is consistent with the BLM's prior agency practice regarding emergency 
situations, beneficial use, and the unavoidable loss of gas, and it 
provides additional support for the approach set forth in this proposed 
rule. Importantly, IRA section 50263 confirms that the concepts of 
``avoidable'' and ``unavoidable'' loss are appropriate for assessing 
royalties. Section 50263 also confirms that the United States' 
pecuniary interest in regulating losses extends to those from upstream 
equipment. But the IRA leaves certain questions open, such as what 
losses qualify as ``unavoidably lost'' and what qualifies as an 
``emergency situation.'' Congress thus has left it to the BLM, as an 
exercise of the agency's expertise and judgment, to determine answers 
to the specific questions the IRA leaves open. As set forth below, this 
final rule addresses these questions in a manner that is consistent 
with the IRA's focus on (and the MLA's and FOGRMA's pre-existing 
emphasis on) ensuring that Federal lessees pay fair and appropriate 
compensation to the Federal Government in exchange for the opportunity 
to conduct their industrial activities under Federal leases.

D. The Final Rule

    The BLM has authority under the MLA to promulgate such rules and 
regulations as may be necessary ``for the prevention of undue waste'' 
\92\ and to ensure that lessees ``use all reasonable precautions to 
prevent waste of oil or gas.'' \93\ For many years, the BLM has 
implemented this authority through restrictions on the venting and 
flaring of gas from onshore Federal oil and gas leases. However, as 
illustrated by the judicial decisions noted previously, before the 
IRA's enactment, courts disagreed about the full scope of the BLM's 
authority to regulate venting and flaring. Requirements that one court 
might consider necessary for the BLM to meet its statutory mandates 
might have been seen as regulatory overreach by another court. 
Consistent with the approach outlined in the proposed rule, and in 
light of all the statutory

[[Page 25388]]

authorities including the IRA, the BLM has chosen to focus on improving 
upon NTL-4A in a variety of ways without advancing elements of the 2016 
Waste Prevention Rule that were the subject of certain judicial 
criticism.
---------------------------------------------------------------------------

    \92\ 30 U.S.C. 187.
    \93\ 30 U.S.C. 225.
---------------------------------------------------------------------------

    As explained in more detail below and in Section IV, the Section-
by-Section Discussion, this final rule makes substantial improvements 
in addressing the waste of Federal and Indian gas, while also 
addressing the Wyoming court's criticisms of the 2016 Waste Prevention 
Rule. First, the requirements unambiguously constitute reasonable waste 
prevention measures that should be expected of an operator. The 
requirements impose fewer overall costs than those of the 2016 Waste 
Prevention Rule and ensure either actual conservation of gas that would 
otherwise be wasted or compensation to the public and Indian mineral 
owners through royalty payments when gas is wasted. This contrasts with 
certain provisions in the 2016 Rule that would have reduced pollution--
but not necessarily reduced waste--by allowing operators to comply with 
analogous EPA standards in place of the BLM requirements.
    Second, to address the Wyoming court's ruling that the BLM's 
authority regarding unit and CA operations on non-Federal and non-
Indian surface is limited, certain requirements in this final rule are 
narrower in scope than similar requirements in the 2016 Waste 
Prevention Rule. Specifically, the final rule's requirements pertaining 
to safety, storage tanks, and LDAR apply only to operations on Federal 
or Indian surface estates.
    Third, the requirements are consistent with the ``prudent 
operator'' standard as that term has been applied in the oil and gas 
jurisprudence.
    Fourth, the final rule has been developed with an eye towards 
avoiding excessive compliance burdens on marginal wells.
    Finally, the BLM is expressly excluding the social cost of 
greenhouse gases from its decisions on any of the proposed waste 
prevention requirements, thereby addressing the Wyoming court's concern 
that the 2016 Rule was inappropriately supported by ``climate change 
benefits.''
    The provisions of this final rule serve straightforward waste 
prevention objectives by promoting gas conservation. To avoid 
situations where oil-well development outpaces the capacity of the 
available gas capture infrastructure, the BLM is requiring operators to 
submit either a WMP, including certification of a valid, executed 
contract to sell the associated gas, or a self-certification of 100 
percent capture of associated gas with oil-well APDs. The BLM 
recognizes that not all venting and flaring can be prevented. In the 
circumstances in which some venting or flaring cannot be prevented 
(e.g., initial production tests or emergencies), the BLM is 
establishing appropriate time or volume limits on royalty-free venting 
or flaring. The BLM is addressing the problem of intermittent flaring 
due to pipeline capacity constraints by establishing a volume limit 
based on oil production for royalty-free flaring caused by inadequate 
capture infrastructure. Requiring royalty payments on venting and 
flaring that exceeds the established limits will both discourage waste 
and ensure that Federal and Indian royalty revenues are not reduced by 
an operator's wasteful practices. The BLM estimates that the royalty-
free flaring limits of the final rule would generate $51 million per 
year in additional royalties. See section 7.6 of the RIA for more 
information.
    This final rule also contains LDAR provisions intended to reduce 
losses of natural gas. Unlike the 2016 Waste Prevention Rule--which 
extended these requirements to State and private surface estates in 
certain situations--the requirements in this final rule apply only to 
operations on the Federal or Indian surface estate, where the BLM has 
express authority and responsibility to regulate for safety, the 
prevention of waste, and the payment of Federal or Indian royalties. 
These requirements would not apply to operations that occur on State or 
private surface tracts committed to a Federal unit or CA. The BLM 
estimates that the requirements of this final rule regarding LDAR would 
result in the conservation of up to 0.5 Bcf of gas each year.
    The BLM acknowledges that the contents of this final rule differ in 
some regards from the 2018 Revision Rule's narrower interpretation of 
the BLM's statutory authority.\94\ Consistent with the BLM's 
understanding of its authority for decades prior to 2018, the BLM has 
reconsidered the relevant conclusions of the 2018 Revision Rule and now 
rejects those conclusions for the following reasons. To begin, nothing 
in the MLA's plain text--which requires lessees to take ``all 
reasonable precautions to prevent waste'' and to abide by rules and 
regulations issued ``for the prevention of undue waste''--suggests that 
the BLM's authority is limited to the promulgation of rules that 
effectively pay for themselves (as measured by balancing compliance 
costs against the value of the recovered gas).\95\ Consistent with this 
text, the BLM's longstanding policy governing venting and flaring has 
assessed the economic feasibility of gas conservation in the context of 
``the total leasehold production, including oil and gas, as well as the 
economics of a field-wide plan.'' See supra, Part III.C.2. As the CDM 
made clear, the BLM's concern under the MLA for nearly four decades 
prior to the 2018 Revision Rule was ``profitable operation of the 
lease, not just profitable disposition of the gas.''
---------------------------------------------------------------------------

    \94\ See 83 FR 49184, 49185-86 (Sept. 28, 2018).
    \95\ 30 U.S.C. 187, 225. Indeed, such a requirement would 
imperil nearly all operational regulations.
---------------------------------------------------------------------------

    Despite suggestions to the contrary in the 2018 Revision Rule, the 
focus of the final rule on overall ultimate resource recovery, not 
lessee profits vis-[agrave]-vis wasted gas, is consistent with the non-
statutory ``prudent operator'' standard. While the prudent operator 
standard rests on an expectation of ``mutually profitable development 
of the lease's mineral resources,'' \96\ it does not follow that 
lessees can maximize their profit by wasting recoverable hydrocarbon 
resources without regard for the lessor's lost royalty revenues or the 
lessor's interest in conserving the gas for future disposition. To the 
contrary, lessees have an obligation of reasonable diligence in the 
development of the leased resources, rooted in due regard for the 
interests of both the lessee and the lessor.\97\ And in the MLA, 
FOGRMA, and the IRA, Congress enshrined the United States' interest, as 
a mineral lessor, in avoiding waste and maximizing royalty 
revenues.\98\ The BLM, in managing oil and gas resources on behalf of 
the United States, may value more production--considering both oil and 
gas production--over a

[[Page 25389]]

longer time period more highly than does an operator, who might be more 
focused on generating near-term profits. None of the authorities 
previously relied upon by the BLM to interpret the ``prudent operator'' 
standard forecloses any Secretarial action that might marginally affect 
lessee profits.\99\

depression of the market.'').

Cal. 2020) (``The statutory language demonstrates on its face that 
any consideration of waste management limited to the economics of 
individual well-operators would ignore express statutory mandates 
concerning BLM's public welfare obligations.'').
---------------------------------------------------------------------------

    In contrast to NTL-4A, this final rule does not allow operators to 
request that flared oil-well gas be deemed royalty-free based on case-
by-case economic assessments. There are a number of reasons for this 
approach. In the first instance, Federal law does not require the 
American taxpayers to forgo royalties on wasted gas due to an 
individual operator's economic circumstances. Although it was the BLM's 
practice to engage in case-by-case economic assessments under NTL-4A, 
that approach is no longer appropriate, as the practical realities of 
oilfield development have changed dramatically since 1980. As the U.S. 
Department of Energy explained in a recent report, ``flaring has become 
more of an issue with the rapid development of unconventional tight oil 
and gas resources over the past two decades'' that has ``brought online 
hydrocarbon resources that vary in their characteristics and 
proportions of natural gas, natural gas liquids and crude oil.'' \100\ 
Consistent with these developments, and as discussed in Section III.A, 
the BLM has witnessed a massive increase in the amount of venting and 
flaring from the 1990's to the 2010's. The average amount of annual 
venting and flaring from Federal and Indian leases between 1990 and 
2000 was 11 Bcf. Between 2010 and 2020, it quadrupled to an average of 
44.2 Bcf per year, with a 157 percent increase in the amount of vented 
and flared gas as a percentage of gas production, and a 102 percent 
increase in the amount of vented and flared gas per barrel of oil 
produced. The upward trend in venting and flaring suggests is likely to 
continue.

    Based on EIA data from 1990 through 2022, U.S. vented and flared 
volumes continue an upward trend that tends to mirror U.S. oil 
production,\101\ which raises a concern that new exploration and 
development is outpacing infrastructure construction. Oil production in 
2019 reached a record high level of 4.5 billion barrels of oil despite 
a relatively low average annual spot price of $57 per barrel. Operators 
may have increased oil production in 2019 to maintain revenues given 
the lower pricing. An increase in oil production to maintain revenues 
may have led to the very high flare volume in that year. While the 
vented and flared volume has decreased since 2019--likely due to 
unrepresentative production during the COVID 19 pandemic that resulted 
in reduced drilling and completions during this time--the data 
demonstrates that, generally, venting and flaring has continued to 
increase since 1990, particularly as compared to the production of oil. 
This rule will work toward reducing the waste from Federal and Indian 
mineral estates.\102\

BILLING CODE 4331-29-C
    The related increase in the number of flaring applications--from 75 
in 2005, to 922 in 2021 has created a significant administrative burden 
for the BLM.\103\ It has also created an estimated information 
collection burden of approximately 23,228 total annual burden hours 
potentially incurred by operators and has led to significant 
uncertainty for operators as hundreds of applications wait to be 
processed.
---------------------------------------------------------------------------

    \103\ See table in the Executive Summary.
---------------------------------------------------------------------------

    Finally, the BLM notes that the bulk of the recent royalty-free 
flaring applications has concerned flaring from wells that are 
connected to pipeline infrastructure. The purpose of the economic 
inquiry under NTL-4A, by contrast, was to determine whether the volumes 
of associated gas production would make the installation of gas-capture 
infrastructure economically viable. CDM 644.5.3E and F. Where the gas-
capture infrastructure has already been built out, there is no need to 
consider the cost and value of its installation against the volume of 
associated gas production. The BLM understands that, as posited by a 
commenter, there may be instances where a gas pipeline connected to an 
oil well is not able to accept that well's gas for a time. In those 
circumstances, an operator may temporarily curtail production or shut 
in the well instead of wasting the gas. Oil and gas production should 
resume when the pipeline can accept the gas.
    One of the primary concerns underlying the BLM's promulgation of 
the 2018 Revision Rule was the compliance burden on ``marginal wells,'' 
i.e., wells that produce approximately 10 barrels of oil or 60 Mcf of 
natural gas per day or less.\104\ The court that vacated the 2016 Waste 
Prevention Rule faulted the BLM for failing to adequately assess the 
impact of that rule on marginal wells.\105\ The court that vacated the 
2018 Revision Rule, however, rejected that concern as unfounded.\106\ 
The BLM does not wish to impose requirements that

[[Page 25391]]

inadvertently cause recoverable oil or gas resources to be stranded due 
to premature lease abandonment, but, as the MLA makes clear, any such 
considerations go to whether particular conservation measures are 
reasonable under the MLA, not whether marginal operations must take 
reasonable measures in the first instance. 30 U.S.C. 225. For example, 
there is no real risk of premature abandonment by requiring the 
operator of a marginal gas well to minimize the loss of gas during 
liquids unloading operations, as required in this rule. Under the final 
rule, an operator of a marginal gas well may vent gas during liquids 
unloading operations royalty-free for 24 hours. If the gas well is not 
put into production within 24 hours and maintenance operations must 
continue, the volume of gas vented is likely very small and the flowing 
pressure very low--otherwise, the operator would be returning the well 
to production. Thus, the marginal time that it takes an operator to 
continue liquids unloading beyond the initial 24 hours will not result 
in significant vented gas and corresponding royalty obligation. 
Furthermore, the BLM has provisions for royalty rate reductions in 43 
CFR 3103.4-1 to encourage the greatest ultimate recovery of oil or gas. 
Therefore, in the unlikely event that compliance with the final rule 
would lead to an operator's premature abandonment of a well, an 
operator may seek royalty relief to continue operations.

---------------------------------------------------------------------------

    The BLM has developed this final rule to avoid excessive and 
unreasonable compliance burdens on marginal wells when balanced against 
the need to reduce waste. In the 2018 Revision Rule, the BLM noted that 
the provisions of the 2016 Waste Prevention Rule that placed a 
particular burden on marginal wells were those pertaining to pneumatic 
controllers, pneumatic diaphragm pumps, and LDAR. In this final rule, 
the requirements for LDAR only apply to Federal or Indian minerals 
produced from facilities located on a Federal or Indian surface estate, 
thereby limiting the number of operators to which the LDAR program 
applies. In addition, the BLM has not included in this final rule the 
provisions in the proposed rule regarding pneumatic controllers and 
diaphragm pumps.
    The BLM acknowledges that, in the 2018 Revision Rule, it asserted 
that additional restrictions on flaring were unnecessary because the 
States with the most significant BLM-managed oil and gas production 
impose regulatory restrictions on flaring from oil wells and that these 
State regulations ``provide[d] a reasonable assurance . . . that the 
waste of associated gas will be controlled.'' \107\ This assertion 
directly contradicted the BLM's prior findings during the promulgation 
of the 2016 Waste Prevention Rule, and a district court held that the 
BLM's decision to rely on State flaring regulations was unjustified 
based on the record evidence.\108\

---------------------------------------------------------------------------

    For this rulemaking, the BLM analyzed the State regulations 
governing flaring, venting, and leaks in the 10 States responsible for 
99 percent of Federal oil and gas production: Alaska, California, 
Colorado, Montana, New Mexico, North Dakota, Oklahoma, Texas, Utah, and 
Wyoming. Summaries of these regulations were collected in a table that 
is available in the docket for this rulemaking at <a href="http://www.regulations.gov">www.regulations.gov</a>. 
While there have been notable advancements in some States since the 
promulgation of the 2016 Waste Prevention Rule--for example, new 
comprehensive flaring regulations have since been adopted in New Mexico 
and Colorado, and new requirements for storage tanks, pneumatic 
equipment, and LDAR have been adopted in Colorado and Utah--State 
regulations vary widely in their scope and stringency.\109\ And, 
importantly, many of the State flaring regulations reserve substantial 
discretion to the State agencies to authorize additional flaring.\110\ 
That discretion creates significant uncertainty about the extent to 
which the BLM can rely on those regulations to protect the interests of 
the United States and Indian mineral owners in minimizing waste and 
maximizing royalty revenues.
---------------------------------------------------------------------------

    \109\ Examples of variations among State regulations include the 
following. Unlike other States, (1) the States of New Mexico, North 
Dakota, Montana, Texas, Alaska, and Oklahoma do not have regulations 
to control losses of gas from pneumatic equipment; (2) Texas' 
requirements to inspect for and repair leaks are focused on storage 
tanks; (3) Alaska does not maintain LDAR requirements; and (4) 
Wyoming's requirements for tanks, pneumatic equipment, and LDAR are 
limited to the Upper Green River Basin ozone nonattainment area.
    \110\ These States are Wyoming, Utah, Montana, Texas, and 
Oklahoma.
---------------------------------------------------------------------------

    In its comments on the proposed rule, the Wyoming Oil and Gas 
Conservation Commission asserts that the BLM incorrectly characterizes 
Wyoming's regulations regarding flaring and gas capture plan 
requirements. Specifically, Wyoming challenges language in the proposed 
rule that ``Wyoming's gas capture plan requirements are not triggered 
until after flaring becomes a problem at the well.'' \111\ 
Specifically, the State objects to the proposed rule's description of 
Wyoming regulations as triggering a plan only after a flaring 
``issue,'' explaining that, in the Commission's view, ``[t]he operator 
must submit a gas capture plan, among other information . . . before 
flaring or it would need to limit flaring to 60 mcf/d or be in 
violation of the [applicable] rule.'' But whether or not these 
contingencies are properly characterized as an ``issue,'' the BLM's 
point--that it was deemed a plan to be useful when the APD is 
submitted--stands. State gas capture plan requirements, by themselves, 
do not provide the BLM, in its capacity as regulator and steward of the 
Federal mineral estate, with an opportunity to render its own 
determinations regarding potential waste when processing an APD.
---------------------------------------------------------------------------

    \111\ 87 FR 73588, 73598 (Nov. 30, 2022).
---------------------------------------------------------------------------

    North Dakota in its comments on the proposed rule takes issue with 
the way the BLM characterized the allowance for variances in North 
Dakota's gas capture regulations. Specifically, the State asserted: 
``In its proposed rule publication, the BLM disingenuously criticizes 
North Dakota's gas capture regulations for allowing variances, and then 
inconsistently proposes a rule that considers associated natural gas as 
unavoidably lost under the same circumstances as 9 out of 10 [North 
Dakota Industrial Commission] variance allowances. . . .'' The BLM 
acknowledges North Dakota's disagreement with the BLM's 
characterization of North Dakota's gas capture regulations. 
Nonetheless, as discussed in the proposed rule, the BLM found 
significant variance in the scope and stringency of State regulations. 
Flaring statistics show that State regulations, by themselves, have not 
been adequate to reduce waste from Federal oil wells, underscoring the 
need for uniformity with respect to Federal mineral interests. As 
discussed further in the section-by-section analysis below, according 
to EIA data from 2017 through 2022, North Dakota accounted for 
approximately 33 percent of the volume of gas flared nationwide but 
only 11 percent of the volume of oil produced nationwide. Wyoming 
accounted for approximately 11 percent of the average total flared gas 
onshore nationwide and 2 percent of the oil produced nationwide. State 
efforts to reduce venting and flaring, though important, do not 
displace the Secretary's duty to prevent undue waste from Federal and 
Indian wells nationwide.\112\ Consequently, the BLM's

[[Page 25392]]

application of a uniform national standard ensures improved royalty 
collection and avoidance of waste. In addition, the Secretary, and not 
the States, is responsible for collecting Federal and Indian royalties. 
The Secretary can best do this by not requiring shifting Federal 
standards in response to any changes to State requirements.

---------------------------------------------------------------------------

    The BLM also recognizes that the EPA has recently finalized 
regulations governing certain aspects of oil and gas production 
operations at 40 CFR part 60, subparts OOOOb and OOOOc, and that these 
regulations can have the incidental effect of reducing the waste of gas 
during production activities. Specifically, EPA's regulations \113\ 
require: (1) capture or flaring of gas that reaches the surface during 
well completion operations with hydraulic fracturing; \114\ (2) storage 
tanks with potential methane emissions of 20 tons or more per year to 
control those emissions (including through combustion); \115\ (3) 
process controllers to be zero emissions; \116\ (4) pumps to be zero 
emissions; \117\ and (5) operators of well sites to develop and 
implement a fugitive emissions monitoring plan.\118\
---------------------------------------------------------------------------

    \113\ 40 CFR part 60 subpart OOOOb regulates greenhouse gases 
(in the form of limitations on methane) and VOCs from various new, 
modified, and reconstructed emission sources across the Crude Oil 
and Natural Gas source category for which construction, 
reconstruction, or modification commenced after December 6, 2022. 40 
CFR part 60 subpart OOOOc includes presumptive standards for 
greenhouse gases (in the form of limitations on methane, a 
designated pollutant), for certain existing emission sources prior 
to December 6, 2022, across the Crude Oil and Natural Gas source 
category.

---------------------------------------------------------------------------

    Although operator compliance with those EPA requirements can reduce 
the waste of natural gas from Federal and Indian leases, they do not 
supplant the need for BLM standards that are adopted pursuant to the 
BLM's independent statutory authority and duties. The BLM further notes 
that, under the CAA, States with one or more existing sources must 
develop and submit State plans to the EPA for approval. Under this 
statutory structure, State plans would implement the emissions 
guidelines for existing sources. Also, EPA's requirements are not a 
substitute for BLM standards because EPA's requirements are focused on 
controlling GHG (in the form of methane) and VOC emissions, rather than 
conserving natural gas, and compliance with the EPA's standards will 
not always reduce the waste of natural gas or assure payment of 
royalties to the United States or to Indian mineral owners. For 
example, an operator can comply with EPA's requirements for storage 
tanks by routing the emissions to combustion (i.e., flaring) and 
therefore eliminating venting from the tanks altogether. That process 
results in the same loss of gas as venting the gas from the tank. 
Therefore, while that process reduces air pollution by prioritizing 
flaring over venting, it does not reduce waste or assure payment of 
royalties because in either scenario, the same amount of gas is lost.
    Based on its review and analysis of State and EPA regulations, the 
BLM finds that it is necessary to establish a uniform standard 
governing the wasteful losses of Federal and Indian gas through 
venting, flaring, and leaks.\119\ The BLM cannot rely on a patchwork of 
State and EPA regulations to ensure that operators of Federal oil and 
gas leases consistently meet the waste prevention mandates of the MLA, 
that the American public receive a fair return for the development of 
the Federal mineral estate, and that the Department's trust 
responsibility to Indian mineral owners is satisfied. The BLM 
acknowledges that this is a change in position from what the BLM stated 
in the Revision Rule regarding analogous State and EPA regulations, a 
change shown to be necessary by the vast increase in flaring in recent 
decades, which demonstrates the ineffectiveness of NTL-4A in 
controlling the waste of gas through venting and flaring. In addition, 
establishing a uniform standard in lieu of case-by-case avoidable and 
unavoidable loss determinations reduces the administrative burden on 
the BLM's limited resources; avoids inconsistent application across the 
States; and simplifies Federal and Indian enforcement.
---------------------------------------------------------------------------

    \119\ The BLM acknowledges that the Wyoming court questioned 
what it described as the BLM's authority to ``hijack'' the 
cooperative federalism framework of the CAA ``under the guise of 
waste management.'' Wyoming 493 F. Supp. 3d at 1066. However, as 
noted elsewhere, this final rule is justified not by any ancillary 
effects on air quality or climate change, but solely on the basis of 
waste prevention--an arena where the BLM has independent statutory 
authority to regulate. See Id. at 1063 (``The terms of the MLA and 
FOGRMA make clear that Congress intended the Secretary, through the 
BLM, to exercise rulemaking authority to prevent the waste of 
Federal and Indian mineral resources and to ensure the proper 
payment of royalties to Federal, State, and Tribal governments.''). 
On its own terms, therefore, the Wyoming court's reference to 
cooperative federalism under the Clean Air Act is inapplicable to 
this final rule, which does not seek to improve air quality and does 
not rely on EPA's CAA regulations.
---------------------------------------------------------------------------

    The RIA for this final rule calculates that this rule would cost 
operators $19.3 million per year, using a 7 percent discount rate, for 
the next 10 years ($19.2 million per year using a 3 percent discount 
rate), while generating benefits to operators of approximately $1.8 
million per year, using a 7 percent discount rate, in the form of 0.45 
Bcf of additional captured gas.\120\ The RIA estimates that this final 
rule would generate $51 million per year in additional royalties. The 
BLM acknowledges that the estimated costs of this rule to operators 
will outweigh the benefits in terms of the estimated monetized market 
value of the gas conserved. However, these benefits do not take into 
account the increase in royalties that will be received by the American 
taxpayer or Indian mineral owners, or include any increase in 
production that could possibly be received from changes in behavior due 
to the avoidable loss threshold, which would also lead to an increase 
in benefits. The BLM notes that the statutory provisions authorizing 
the BLM to regulate oil and gas operations for the prevention of waste 
do not impose a net-benefit requirement.
---------------------------------------------------------------------------

    \120\ The cost-benefit analysis contained in the RIA was 
generated to comply with Executive Order 12866 and is not required 
by the statutes authorizing the BLM to regulate for the prevention 
of waste from oil and gas leases.
---------------------------------------------------------------------------

    Separately, the reduced methane emissions associated with the final 
rule provide a monetized benefit to society (in the form of avoided 
climate damages) of $17.9 million per year over the same time frame, 
leading to an overall net monetized benefit from the rule of $360,000 
to $441,000 a year, as well as additional unquantified benefits. (See 
Appendix A of the RIA regarding unquantified benefits.) The basis for 
the BLM's estimates of social benefits from reduced methane emissions--
namely, the social cost of greenhouse gases (SC-GHG)--is explained in 
detail in Appendix A of the RIA. To be clear, although the BLM is 
reporting its estimates of the social benefits of reduced methane 
emissions here and in the RIA, the purpose of that reporting is solely 
to provide the most complete and transparent accounting of the costs 
and benefits of the rule for the public's awareness. The BLM considered 
but did not rely on climate-related costs and

[[Page 25393]]

benefits when reaching the policy decisions in this rule. The 
requirements of this final rule reflect reasonable measures to avoid 
waste, regardless of any impacts with respect to climate change.

IV. Discussion of Public Comments on the Proposed Rule

    This section of the preamble summarizes the major categories of the 
public comments that the BLM received in response to the proposed rule, 
as well as the BLM's responses. Detailed discussion regarding the 
substantive comments on the proposed rule that the BLM received, the 
BLM's responses to those comments, and changes that the BLM made in the 
final rule are provided in Section V (Section-by-Section Discussion) of 
this preamble.
    The public comment period for the proposed rule ended on January 
30, 2023. During the 60-day public comment period, the BLM received 
3,323 total comments submitted from Federal, State, local governments, 
local agencies, Tribal organizations, industry representatives, 
individuals, and other external stakeholders. Of the 3,323 comment 
letter submissions, 2,892 were template form letters from seven 
different organizations, leaving 134 additional unique commenters. From 
these 141 unique commenters, the BLM identified 1,123 unique comments 
on the proposed rule.
    Several commenters requested that the BLM hold meetings to take 
public input on the proposed rule before the comment period ended. The 
BLM held additional meetings with the Santa Rosa Rancheria Tachi-Yokut 
Tribe on December 1, 2022; the Mandan, Hidatsa and Arikara Nation (MHA 
Nation) on December 6, 2022, and February 13, 2023; and the Southern 
Ute Indian Tribe on April 10, 2023, May 25, 2023, and June 8, 2023.
    All relevant comments are posted at the Federal eRulemaking portal:

Comments on Federalism Implications
    Summary of Comments: Several commenters suggested that the BLM 
withdraw the proposed rule on the grounds that it exceeds Federal 
statutory authority or, in the alternative, revise the proposed rule to 
reflect a federalism framework to affirm the States' authority over 
State and local mineral resources within the State's boundaries. To 
that end, the commenters stated that the final rule has sufficient 
federalism implications to warrant the preparation of a federalism 
summary impact statement. In support of this position, the commenters 
claimed that this rule unlawfully focuses on air quality emissions 
rather than waste, and that this focus violates the cooperative 
federalism framework under the CAA. The commenters referenced the BLM's 
purported preference for flaring over venting and claimed that this 
preference for flaring is unsupported because the BLM's regulatory 
authority is limited to waste prevention and does not include safety as 
a guise to regulate air quality.
    Response: The BLM disagrees with the commenters. The BLM developed 
this rule based on its statutory authority to prevent and reduce the 
waste of natural gas produced from Federal and Indian (not State) land 
through improved regulatory requirements pertaining to venting, 
flaring, and leaks, while ensuring a fair return to the American 
public.\121\ It does not override the States' or Tribes' more stringent 
requirements for flaring and gas capture or waste prevention measures 
on State or Indian lands. Operators with leases on Federal lands must 
comply with the Department's regulations and with State requirements to 
the extent that they do not conflict with the Department's regulations. 
As stated in the Federalism section of this rule, below, although the 
final rule will affect the relationship between operators, lessees, and 
the BLM, it will not directly impact States. Accordingly, a federalism 
summary impact statement is not warranted.
---------------------------------------------------------------------------

    \121\ 30 U.S.C. 187.
---------------------------------------------------------------------------

    Any claim that this rule violates the cooperative federalism 
framework under the CAA is likewise unfounded. As discussed below, the 
waste prevention rule is intended to prevent the waste of gas from 
Federal oil and gas leases and is, therefore, not an air quality 
emissions rule. As noted in the preamble to the proposed rule, the 
Wyoming court questioned the BLM's authority to--in the court's view--
preempt cooperative federalism under the CAA, using a pretext of waste 
prevention. But as consistently explained throughout this preamble, 
this final rule is authorized by the BLM's independent statutory 
authority to prevent waste of natural gas and is not focused on 
achieving any ancillary effects on air quality or climate change. As 
such, cooperative federalism requirements under the CAA do not apply to 
this final rule.\122\ Moreover, the Department's regulations governing 
oil and gas operations on the public lands have long required operators 
to conduct operations in a manner that is protective of natural 
resources, environmental quality, and public health and safety. See 43 
CFR 3162.5-1 and 3162.5-3. As the BLM stated in the proposed rule and 
reiterated in the Sec.  3179.50 Safety discussion in this final 
preamble, combusting gas rather than venting it into the surrounding 
air is safer for operations due to the gas' explosiveness and the risk 
to workers from hypoxia and exposure to various associated pollutants.
---------------------------------------------------------------------------

    \122\ We have found no statutory support for the argument that 
any regulation that has ancillary effects on air quality is per se 
preempted by the CAA.
---------------------------------------------------------------------------

Comments on State or Tribal Variances
    Summary of Comments: At least one commenter said that, as a 
sovereign regulatory authority over the State and private minerals 
located within the State's boundaries, it objected to the requirement 
that the State and private mineral holders must seek variances from the 
waste prevention requirements. This commenter also concluded that the 
variance provision was improper because, according to the commenter, 
the rule is an air quality emissions rule.
    Response: The BLM decided not to include the provisions for State 
or Tribal requests for variances that were found in the proposed rule 
at 43 CFR 3179.401 in part because it concluded that the proposed 
variance provision could lead to regulatory uncertainty. As stated 
above in response to comments regarding federalism implications, the 
final rule does not preempt more stringent requirements for flaring, 
gas capture, or waste prevention under State or Tribal law, as 
appropriate. Operators with oil and gas leases on Federal lands must 
comply with the Department's regulations and with State requirements, 
to the extent that they do not conflict with the Department's 
regulations, and similarly operators of Tribal leases must comply with 
both Tribal and Departmental regulations. Moreover, the waste 
prevention rule is intended to prevent the waste of gas from Federal 
and Indian oil and gas leases and is, therefore, not an air quality 
emissions rule, as further discussed below.
    Comments on Air Quality
    Summary of Comments: Some commenters claimed that this rule seeks 
to address air quality rather than waste prevention and that the BLM 
should defer to the Environmental Protection Agency (EPA) or State 
agencies to regulate air quality under the CAA and other authorities.
    Response: The BLM disagrees. As discussed above, the rule responds 
to the BLM's statutory obligation to prevent waste. The MLA requires 
the BLM to subject all oil and gas leases to the condition that the 
lessee ``use all

[[Page 25394]]

reasonable precautions to prevent the waste of oil or gas developed in 
the land'' and underscores that ``[v]iolations of the provisions of 
this section shall constitute grounds for the forfeiture of the 
lease.'' \123\ The Act also provides the Secretary with authority to 
subject leases to ``such rules . . . for the prevention of undue waste 
as may be prescribed by [the] Secretary.'' \124\ Even the Wyoming 
court--which vacated portions of the 2016 Rule after the court found it 
was primarily justified by air quality benefits--recognized that the 
BLM does in fact have authority to promulgate and impose rules designed 
to reduce waste, provided such rules are ``independently justified as 
waste prevention measures pursuant to [the BLM's] MLA authority.'' 493 
F. Supp. 3d at 1067. As explained below, the waste prevention 
provisions of the final rule are independently justified, and the air 
quality comments from oil-and-gas industry representatives do not 
demonstrate otherwise.

    Notwithstanding this authority, a commenter opposed to much of the 
proposed rule stated that the BLM should avoid conflict or duplication 
with EPA's and the States' exercise of their ``exclusive authority'' 
over air quality. The commenter added that CAA regulation and 
enforcement fall within other Federal and State agencies' ``exclusive 
jurisdiction.'' The commenter also referred to what it described as the 
``exclusive air quality purview'' of EPA and the States, while arguing 
that the BLM should not ``assume'' such authority.
    The BLM is not regulating air quality in this rule. The BLM is 
regulating to prevent waste and to assure payment of royalties pursuant 
to independent and express statutory authority. The ability of EPA and 
the States to regulate air pollution does not bar the BLM from 
fulfilling its statutory obligation to regulate waste. Addressing waste 
may have some effects on air pollution and its connection to human 
health and welfare, which is the primary responsibility of the EPA, 
States, and local governments.\125\ But the possibility that a BLM rule 
might have incidental effects on air quality does not strip the BLM 
from exercising its clear, express statutory authority under the MLA to 
prevent or reduce waste of gas. Cf. Wyoming, 493 F. Supp. 3d at 1063 
(acknowledging that ``a regulation that prevents wasteful losses of 
natural gas from venting and flaring necessarily reduces emissions of 
that gas''). The MLA is designed to encourage diligent development of 
Federal oil and gas resources, avoid waste, and generate revenue, see 
Public Law 66-145, sections 15, 16, 26, 27, while the CAA seeks to 
reduce air pollution to protect the public health and welfare. 42 
U.S.C. 7401(a)(2), (b)(1). The EPA's regulation of methane emissions 
does not excuse the BLM from its obligation to prevent waste of and 
generate revenue from Federal oil and gas resources. In the proposed 
and final rules, the BLM has explained why it is implementing certain 
measures for waste prevention or other matters attendant to BLM 
authority (e.g., safety and royalty measurement).

Cir. 2013) (emphasis added).

    Another comment expressed concern about conflicts between the MLA 
and various air quality regulations and statutes. The commenter 
specified that the rule should not ``create potential conflicts or 
duplication with EPA and State requirements promulgated pursuant to the 
CAA and State authorities.'' Another comment expressed concern about a 
``potentially conflicting and duplicative BLM regulatory overlay'' on 
existing and forthcoming regulations on methane and VOC emissions. As 
noted, the CAA and the MLA pursue different statutory goals, which may, 
as a general matter, reduce the possibility of conflict among specific 
regulations promulgated by the BLM and EPA. The successful prevention 
of the waste of gas may also lead to air quality effects. Nonetheless, 
we have examined the EPA's methane-related regulations and the EPA's 
OOOO series rules \126\ and have avoided conflict by focusing on the 
BLM's waste prevention and royalty measurement mandates, while 
acknowledging ancillary effects to air quality from this final rule. We 
have found no provision of the final rule that prevents compliance with 
EPA's regulations.

---------------------------------------------------------------------------

    Enactment of the CAA did not repeal any section of the MLA or any 
of the BLM's other statutory authorities. Thus, neither the CAA, nor 
the programs of the EPA, States, or Tribes relieve the BLM of its 
statutory obligations to prevent waste and to assure royalty 
accountability. Similarly, nothing in this final rule interferes with 
any air quality regulation of EPA, the States, or Tribes.
    In sum, we conclude that the final rule is a proper exercise of the 
agency's authority under the MLA and other statutes (discussed above) 
to promulgate regulations for the prevention of waste. Its ancillary 
effects on air quality are not disqualifying and, despite commenters' 
suggestions to the contrary, do not defeat the provisions of the MLA 
discussed above, as reinforced by the IRA.
    Commenters also suggested that the BLM's proposed rule implicates a 
``major question'' as that term is used in West Virginia v. EPA, 142 S. 
Ct. 2587 (2022). In that case, the Supreme Court vacated an EPA 
rulemaking because, according to the Court, EPA ``claimed to discover 
in a long-extant statute an unheralded power representing a 
transformative expansion in its regulatory authority,'' ``located that 
newfound power in the vague language of an ancillary provision of the 
Act,'' and ``adopted a regulatory program that Congress had 
conspicuously and repeatedly declined to enact itself.'' Id. At 2610. 
The Supreme Court went on to hold that, in such circumstances, 
colorable congressional authorization was insufficient; the agency must 
instead point to ``clear congressional authorization'' for its actions. 
Id. At 2614.
    The final rule is not the type of ``extraordinary'' Rule that 
implicates a major question. See Id. At 2609. The BLM has not claimed 
to discover any novel authority in the MLA. Rather, a lessor's legal 
capacity to prevent waste extends back at least to the common law 
prudent operator standard. Congress codified the Secretary's authority 
and obligation to prevent waste in 1920, when it drafted the MLA to 
provide that ``[e]ach lease shall contain . . . a provision that such 
rules . . . for the prevention of undue waste as may be prescribed by 
said Secretary shall be observed.'' \127\ Congress affirmed the BLM's 
authority and obligations in 2022, when, in the IRA, it required the 
BLM to charge royalties on gas that was not ``unavoidably lost'' but 
did not otherwise define that term.\128\ By the same token, the MLA 
provisions at issue here are not ``ancillary:'' they have been squarely 
and explicitly relied upon for decades in efforts to reduce waste. In 
short, the Department's authority to regulate waste is--and always has 
been--a component of its authority to lease.
---------------------------------------------------------------------------

    \127\ See 30 U.S.C. 187).
    \128\ As previously stated in the preamble, the IRA provides 
that, for leases issued after August 16, 2022, royalties are owed on 
all gas produced from Federal land, subject to certain exceptions 
for gas that is lost during emergency situations, used for the 
benefit of lease operations, or ``unavoidably lost.''
---------------------------------------------------------------------------

    Beyond this longstanding authority, the BLM's rule is narrower than 
the

[[Page 25395]]

Supreme Court's characterization of the rule in West Virginia. That 
rule, according to the Court, ``balance[ed] the many vital 
considerations of national policy implicated in deciding how Americans 
will get their energy.'' 142 S. Ct. at 2612. Accord Biden v. Nebraska, 
143 S. Ct. 2355, 2372 (2023) (striking down student loan forgiveness 
program on the grounds that ``no regulation premised on [the ostensibly 
authorizing statute] has even begun to approach the size or scope of 
the Secretary's program''). Here, the BLM is changing its regulations 
to marginally adjust waste prevention--merely one component of oil and 
gas production--under the MLA and the Indian minerals statutes. Those 
statutes, in turn, reflect merely one component of the nation's total 
oil and gas production, which itself is merely one component of the 
nation's total energy mix.
    Nor has Congress considered and rejected the measures in this final 
rule. Commenters did not provide evidence showing that the most 
significant portions of this rule--new requirements for APDs, 
clarification of the term ``avoidably lost'', and leak detection--have 
been the subject of congressional debate. Ultimately, ``common sense'' 
indicates that the MLA and the IRA reflect precisely ``the manner in 
which Congress [would have been] likely to delegate'' the technical and 
discrete issue of waste prevention vis-[agrave]-vis public minerals. 
West Virginia at 2609. The BLM therefore did not make changes based on 
these comments.
Comments on Ways To Minimize Waste of Natural Gas During the Leasing 
Stage
    Summary of Comments: The BLM requested public comment on how it can 
improve its processes pertaining to the leasing stage of development to 
minimize the waste of natural gas during later stages of development. 
Some commenters recommended that the BLM require WMPs at the land use 
planning stage or when an operator nominates parcels of land for 
leasing under an Expression of Interest. Although at least one 
commenter recommended that the BLM require a WMP during the leasing 
stage, at least one other commenter objected to that proposal. At least 
one commenter objected to the BLM's proposed requirement that an APD 
include a WMP and specifically protested what it claimed to be vague 
standards for approval or denial of the plan. The commenter further 
stated that this proposed provision potentially duplicates a State's 
gas capture plans and may delay or cause the State permit to expire if 
the rule required the operator to submit information that conflicts 
with the State's requirements. Another commenter requested that the BLM 
remove any requirement for the operator to provide confidential 
business information or otherwise unavailable information in the WMP 
because the operator does not possess this information and it is not 
helpful for the specific purpose it is intended.
    Response: As discussed further in the Section-by-Section 
discussion, the BLM in this final rule has retained the requirement to 
submit a WMP with a Federal or Indian oil and gas APD, or, in the 
alternative, submit a self-certification statement that would commit 
the operator to capturing 100 percent of the associated gas produced 
from an oil well and would obligate the operator to pay royalties on 
all lost gas except for gas lost through emergencies. The BLM has 
reviewed the comments and changed the provisions for a WMP. Under the 
final rule, the operator may submit either: (1) a self-certification 
statement committing the operator to capture 100 percent of the 
associated gas less any on-lease use of associated gas pursuant to 
subpart 3178; or (2) a WMP that includes, among other requirements, a 
certification that the operator has a valid, executed gas sales 
contract for the associated gas. A WMP is subject to the avoidable loss 
flaring limit established in final Sec.  3179.70, while self-
certification is a statement that the operator will be able to capture, 
as defined in final Sec.  3179.10, 100 percent of the associated gas. 
In the case of self-certification, 100 percent of the oil-well flared 
gas has a royalty obligation from the date of first production until 
the well is plugged and abandoned, less any on-lease use of associated 
gas pursuant to subpart 3178.
    The BLM has added the self-certification option to the final rule 
in response to comments that the waste prevention plan requirement is 
overly burdensome for industry and provides little benefit to the BLM. 
The self-certification option serves the dual purposes of providing 
operators with a less burdensome alternative, while simultaneously 
reducing waste through the encouragement of capture, a term defined in 
the proposed rule and unchanged in the final rule. The updated 
requirement provides the operator with the flexibility to secure a 
valid, executed gas sales contract or elect to expedite approval of the 
APD with a self-certification statement. In making this decision, 
operators may consider, e.g., the time to secure a gas sales contract, 
the desired date of the oil well completion, or the flaring royalty 
obligation associated with either a WMP or self-certification.
    The BLM disagrees with a commenter's belief that the WMP 
potentially duplicates a State's gas capture plans or would delay or 
cause a State permit to expire if the rule requires the operator to 
provide confidential or otherwise unavailable information. In any State 
or on any Tribal lands with essentially the same requirements as this 
final rule, this rule has no additional substantive burden on 
operators. As previously stated, the final rule does not preempt any 
State's or Tribe's requirements that are more stringent with respect to 
flaring and gas capture requirements or for waste prevention. There is 
nothing unique about this rule's interaction with State or Tribal law; 
those laws have always applied to operations regulated by the BLM, 
except on the rare occasion in which they prevent compliance with BLM 
regulations. More stringent State or Tribal regulations apply of their 
own force. Operators with leases on Federal lands must comply with both 
the Department's regulations and with State or Tribal requirements, to 
the extent that the non-Federal requirements do not conflict with the 
Department's regulations. None of the commenters have shown that any 
portion of the rule would interfere with the States' or Tribes' ability 
to regulate oil and gas operations on Federal lands or that the 
operator cannot comply with both the final rule and State or Tribal 
regulations.
    After carefully considering the comments received concerning 
confidential information that may be included in the WMP, as well as 
information that is not within the operator's purview, the BLM has 
revised the required information in the WMP to align with the BLM's 
waste prevention objectives more closely. For example, the BLM is not 
finalizing the proposal for operators to identify in the WMP the 
anticipated daily capacity of the pipeline at the anticipated date of 
first gas sales from the proposed well, or the proposal to include any 
plans known to the operator for expansion of pipeline capacity for the 
area that includes the proposed well. Commenters indicated that this 
information could be confidential and proprietary information that 
belongs to midstream companies and that oil and gas operator are 
obligated to keep confidential. We agree.

Comments on Definition of ``Unreasonable and Undue Waste of Gas'' in 
the Loss of Oil or Gas, Avoidable or Unavoidable Determination, and the 
Prudent Operator Standard
    ``Unreasonable and undue waste of gas,'' avoidable or unavoidable 
determination, and the prudent operator standard are interrelated and 
warrant a combined discussion. Accordingly, the following summary of 
comments and the BLM's response will cover these three concepts.
    Summary of Comments: In the proposed rule, the BLM requested public 
comment on the definition of ``unreasonable and undue waste of gas,'' 
which the BLM considers when determining whether the loss of oil or gas 
is avoidable or unavoidable. Commenters suggested that the definition 
include an express reference to economic feasibility because, according 
to the commenters, the rule will become unwieldy and difficult for the 
BLM to administer without this economic consideration. Commenters 
expressed concern that the proposed avoidable loss threshold ignores 
whether the lessee is acting reasonably and prudently without any 
evaluation of the operator's actual economic circumstances, and that 
flaring is not automatically ``waste.''
    Response: We disagree with the commenters' suggestion that the rule 
should accommodate economic feasibility for individual flaring cases. 
In the proposed rule, the BLM explained that ``lessees have an 
obligation of reasonable diligence in the development of the leased 
resources, rooted in due regard for the interests of both the lessee 
and the lessor.'' 87 FR 73597. The lessor has an interest in collecting 
royalties on production and in conserving gas for future disposition. 
The proposed rule also explained that the prudent operator standard 
looks to the operation of a lease as a whole and considers the 
interests of both the lessees and the lessors in conserving and 
developing the Federal mineral resource. However, with the final rule, 
the BLM has decided to not carry forward the proposed definition of 
``unreasonable and undue waste of gas'' and removed the term from Sec.  
3179.10 and references to the definition in Sec. Sec.  3179.100 and 
3179.70(b). The BLM has determined that the definition might create 
unnecessary confusion and is not relevant for purpose of carrying out 
Sec. Sec.  3179.100 and 3179.70(b).
    Several commenters objected to the BLM's discussion of the prudent 
operator standard, which focuses on the lease as a whole, and argued 
that the prudent operator standard forecloses the BLM from imposing 
measures for waste prevention that may, in some situations, require an 
operator to spend more than the value of potentially wasted gas. That 
is, the commenters did not contend that the BLM's rule would render 
leases unprofitable on the whole, but merely that the prevention of 
marginal waste might not, from the individual operator's perspective 
(and particularly for low volume producers) pay for itself.
    In support of this reading, the commenters cited the BLM's 
regulatory definition of waste as:

any act or failure to act by the operator that is not sanctioned by 
the authorized officer as necessary for proper development and 
production and which results in: (1) A reduction in the quantity or 
quality of oil and gas ultimately producible from a reservoir under 
prudent and proper operations; or (2) avoidable surface loss of oil 
or gas.

43 CFR 3160.0-5 (emphasis added). The definitions in 43 CFR 3160.0-5 
explicitly apply to part 3160 only, and the BLM notes that most of the 
regulations in this final rule appear in part 3170. In any event, there 
is no conceptual inconsistency between the regulations in that part and 
the definitions in part 3160. The definition of ``waste'' in part 3160 
indicates that gas is wasted where, inter alia, loss is avoidable, and 
the final definitions in part 3170 explain when loss is avoidable and, 
separately, what subset of ``waste'' is ``undue.'' To avoid confusion, 
the final rule has deleted the word ``prudent'' where it had occurred 
in the proposed rule. See Sec.  3179.41(a) and (b).
    It is unclear precisely why commenters believe this provision is 
inconsistent with a fair reading of the non-statutory prudent operator 
standard and why they believe that standard requires a narrower 
reading. It is true, as commenters note (and as discussed elsewhere in 
this rule), that NTL-4A and IBLA caselaw have previously recognized 
``unavoidably lost'' gas--the waste implicitly contemplated by 43 CFR 
3160.0-5(1)--as excluding those cases where, in a case-by-case 
determination, ``the Supervisor determines that said loss resulted from 
. . . the failure of the lessee or operator to take all reasonable 
measures to prevent and/or control the loss.'' NTL-4A. II.A. For the 
reasons explained elsewhere in this preamble, such case-by-case 
determinations are no longer sufficient for the BLM's fulfillment of 
its obligations to prevent waste. Here, we explain why the authorities 
cited by some commentors do not require individualized determinations.
    Thus, for example, commenters' frequent citations to court 
decisions and to the IBLA decisions in Ladd Petroleum Corporation and 
Rife Oil Properties are misplaced. Ladd did not address the meaning of 
the prudent operator standard or avoidably lost gas at all, and instead 
held that, where the BLM had chosen to issue certain guidance detailing 
case-by-case feasibility determinations, the substance of that guidance 
should govern in pending administrative appeals. 107 IBLA 5 (1989). 
Rife Oil, meanwhile, stands for the proposition that NTL-4A provided 
for case-by-case waste determinations, not that the MLA and FOGRMA 
require such determinations. 131 IBLA 357, 373-75 (1994).\129\ The same 
is true for the cases cited by Ladd and Rife Oil. See Lomax Exploration 
Co., 105 IBLA 1 (1988) (concluding that NTL-4A applied to certain 
venting or flaring without passing on the BLM's discretion to modify or 
depart from NTLA-4A); Mallon Oil Co., 107 IBLA 150, 156 (1989) (same); 
Maxus Exploration Co., 122 IBLA 190, 198 n.1 (1992) (``As the word 
`economic' is used in NTL-4A, it relates to a lessee's argument that 
conservation of the gas is not viable from an economic standpoint . . . 
.'') (emphasis added).
---------------------------------------------------------------------------

    \129\ In dicta, the Rife Oil decision considered a possible 
``read[ing] [of] NTL-4A as barring the venting of gas . . . without 
regard to whether it was avoidably lost'' within the meaning if NTL-
4A, 131 IBLA at 374, hypothesizing that such a reading ``would lead 
to potential waste of oil where production of oil was marginally 
economic but production of gas was not economic and the requirement 
to market the gas caused a premature abandonment of the well.'' Id. 
at 374 n.6 (emphasis added). This abstract hypothetical says nothing 
regarding the United States' general authority as lessor to balance 
by regulation the waste from potential loss of gas against the waste 
from potential loss of oil, much less does it evaluate the specific 
balancing the BLM has performed throughout in this rule.
---------------------------------------------------------------------------

    Some commenters also concluded that the IRA essentially codified 
NTL-4A's definitions of ``avoidable'' and ``unavoidable,'' reasoning 
that Congress must have been aware of the BLM's pre-2016 definitions of 
those terms. The IRA, however, did not provide a statutory definition 
of ``avoidable'' or ``unavoidable,'' and did not prohibit the Secretary 
of the Interior from promulgating a rule to define and implement those 
terms under her existing statutory authorities. See, e.g., 30 U.S.C. 
189.\130\ The IRA did not amend the MLA to require the type of case-by-
case evaluations the commenters seek, and commenters have

[[Page 25397]]

not provided ``the sort of overwhelming evidence of [congressional] 
acquiescence'' to NTL-4A's definitions ``necessary to support [their] 
argument in the face of Congress's failure to amend.'' Sackett v. EPA, 
143 S. Ct. 1322, 1343 (2023).\131\
---------------------------------------------------------------------------

    \130\ ``The Secretary of the Interior is authorized to prescribe 
necessary and proper rules and regulations and to do any and all 
things necessary to carry out and accomplish the purposes of [the 
MLA].''
    \131\ In the context of drainage (the original problem addressed 
by the prudent operator standard) the BLM has promulgated 
regulations detailing a lessee's obligations to avoid uncompensated 
drainage or to pay compensatory royalties. 43 CFR 3162.2-2 to 
3162.2-15. Thus, as in this final rule, the BLM by regulation 
specifies the duties of lessees without reliance upon common law 
standards, including the prudent operator standard.
---------------------------------------------------------------------------

    Commenters also cited FOGRMA's provision that lessees are liable 
for royalties when ``waste is due to negligence . . . or . . . failure 
to comply with any rule or regulation . . . under any mineral leasing 
law.'' 30 U.S.C. 1756 (emphasis added). This provision says nothing of 
the prudent operator standard and imposes royalty for failure to comply 
with any applicable regulations, including the regulations at issue in 
this rule. Some commenters attempted to downplay this language by 
characterizing FOGRMA as requiring compliance only with ``specific 
regulatory requirement[s],'' but the relevant statute does not include 
the word ``specific,'' and the commenters provided no explanation as to 
how that concept, even if somehow embodied in FOGRMA, would operate to 
exclude from royalty obligations those regulations--like this final 
rule--designed to conserve the Federal and Indian mineral estates.
    Commenters also cited to the District of Wyoming's decision 
addressing the merits of the 2016 Rule, but that decision likewise does 
not compel the commenters' preferred reading of the prudent operator 
standard or elevate it to a statutory limit on the Secretary's 
rulemaking authority. The relevant portion of the decision began by 
reciting the history of the BLM's case-by-case evaluation of 
feasibility, citing Rife Oil and the IBLA's Ladd Petroleum decision. 
See Wyoming, 493 F. Supp. 3d at 1073-74.\132\ The Wyoming court then 
concluded that although the ``MLA's waste provisions leave room for 
interpretation,'' the BLM's 2016 construction of those provisions was 
unlawful because the BLM had ``primarily'' sought to ``benefit the 
environment and improve air quality,'' as reflected in the BLM's 
reliance on the 2016 Rule's ancillary effects. Id.
---------------------------------------------------------------------------

    \132\ In the Wyoming decision, the court characterized the 
IBLA's Ladd holding as ``remanding BLM decision that flared gas was 
avoidably lost for determination of `whether in fact it was 
economically feasible to market the gas' and explaining that 
interpretation of NTL-4A giving operator opportunity to show gas was 
not marketable `is consistent with the intent of the underlying 
statutory and regulatory authority.' '' This statement is a quote 
from a headnote in IBLA's decision, not the decision itself. Ladd 
Petroleum Corp., 107 IBLA 5 (1989).
---------------------------------------------------------------------------

    In both its proposed and final rules, however, the BLM is 
exclusively focused on addressing waste and royalty payments, along 
with certain safety provisions, and has disavowed in form and substance 
any effort to regulate air quality in a manner entrusted to EPA and 
that agency's State and Tribal partners, including by eschewing any 
reliance on ancillary effects on the atmosphere. Instead, the BLM has 
promulgated this rule purely to curb the excessive, accelerating, and 
nationwide waste of Federal and Indian gas and to curb localized 
hazards to human health and safety from operations. As it did in the 
2016 Rule, the BLM has acknowledged its ``decades-long practice of 
factoring in operator economics on a case-by-case basis when 
determining whether a loss was avoidable,'' explaining in this 
rulemaking why the MLA's waste provisions--which ``leave room for 
interpretation''--now justify a suite of nationwide standards and 
important flexibilities for specific operators and leases. Id. 
Therefore, the final rule does not conflict with the Wyoming court's 
decision.
    In dicta, the Wyoming court also discussed the prudent operator 
standard without reference to considerations like the social cost of 
methane. Id. The District Court cited caselaw and the MLA for the 
general proposition that ``[o]il and gas leases--including those 
between the Federal Government and its lessees--are intended to ensure 
mutually profitable development of the lease's mineral resources.'' Id. 
(emphasis added). Indeed, the cases cited by the Wyoming court stand 
for the proposition that a mineral lease is fundamentally different 
from ``a business into which [the lessee] puts property, money, and 
labor exclusively his own, the profits and losses in which are of 
concern only to him, and the conduct of which may be according to his 
own judgment . . . .'' Brewster v. Lanyon Zinc Co., 140 F. 801, 814 
(8th Cir. 1905). Instead, the ``interest in the subject of the lease . 
. . make the extent to which . . . the operations are prosecuted of 
immediate concern to the lessor.'' Id. As the BLM noted in the proposed 
rule and reaffirms here, these general propositions do not specify 
precisely how the United States, as manager of the Federal mineral 
estate, must perform its statutory duty of preventing waste, and, 
specifically, whether it must do so on a case-by-case basis or elevate 
an operator's profit maximization over the United States' duties to the 
taxpayers and to Indian mineral owners.
    As discussed in Brewster, one way the lessor may elect to enforce 
this interest is by seeking expedited production, so that the lessee's 
failure to develop the lease does not ``exhaust'' the oil and gas 
``through the operation of wells on adjoining lands.'' Id. See also 
Gerson v. Anderson-Prichard Prod. Corp., 149 F.2d 444, 446 10th Cir. 
1945 (``A lease of this kind contains an implied covenant that the 
lessee will exercise reasonable diligence in the development of the 
leasehold and in the protection of it from undue drainage through wells 
on adjacent lands.'') (emphasis added). The prudent operator standard 
chiefly applies to these drainage cases, in which it protects the 
operator from overbroad allegations of a ``breach of the covenant for 
the exercise of reasonable diligence.'' Brewster, 140 F. at 814-15 
(emphasis added). Given the significant cost of drilling a new well 
\133\ ``and the fact that the lessee must bear the loss if the 
operations are not successful,'' the standard shields the lessee from 
demands to drill unprofitable wells ``even if some benefit to the 
lessor will result'' from less drainage. Brewster, 140 F. at 814 
(emphasis added). See also Olsen v. Sinclair Oil & Gas Co., 212 F. 
Supp. 332, 333 (D. Wyo. 1963) (``the `prudent operator' rule . . . is 
to the effect that the lessee has no implied duty to drill an offset 
well if reasonably prudent operators would not drill it'').
---------------------------------------------------------------------------

    \133\ According to a 2016 report by the Energy Information 
Agency: ``Total capital costs per well in the onshore regions 
considered in the study [ranged] from $4.9 million to $8.3 million, 
including average completion costs that generally fell in the range 
of $ 2.9 million to $ 5.6 million per well. However, there is 
considerable cost variability between individual wells.'' Trends in 
U.S. Oil and Natural Gas Upstream Costs, p.2 (U.S. E.I.A. March 
2016).
---------------------------------------------------------------------------

    In other words, the prudent operator standard originally arose in 
and chiefly applies to drainage, but the principles underlying the 
standard equally enable the lessor to exercise its ``immediate 
concern'' in the lease by requiring conservation of the mineral estate. 
Brewster at 814. The policy concerns ordinarily animating application 
of the prudent operator standard are not as salient in the latter case, 
where there is materially less risk that the lessor will seek to reap a 
profit by asking the lessee to shoulder a significant net loss. A 
lessor requiring the lessee to conserve marginally more resources 
generally does not, for example, seek royalties from significant 
capital expenses, borne by the lessee, ``incident to the work of 
exploration,'' Id., or to ``drill[ing] an

Interior to ``obtain for the public a reasonable financial return on 
assets that `belong' to the public,'' while requiring only ``some 
incentive'' for development. Cal. Co. v. Udall, F.2d 384, 388 (D.C. 
Cir. 1961).

common advantage of both the lessor and lessee.'') (emphasis added).
---------------------------------------------------------------------------

    In all events--and contrary to the commenters' arguments in support 
of individualized economic analyses--any application of the prudent 
operator standard considers the profitability of the entire lease, not 
whether individual volumes of potentially wasted gas are themselves 
profitable for the lessee. See Gerson, 149 F.2d at 446 (``the lessee 
does not bear an implied obligation . . . unless, taking into 
consideration all existing facts and circumstances, it would probably 
produce oil in sufficient quantity to repay the whole sum required to 
be expended, including the cost of drilling, equipping, and operating 
the well, and also pay a reasonable profit on the entire outlay''). For 
the reasons discussed in this preamble, the BLM has reached reasonable 
determinations, with respect to each of its waste prevention measures, 
that the marginal restrictions in the final rule will not render a 
lease unprofitable.
    On this score, some commenters argued that the draft RIA shows that 
the costs of the proposed rule exceed the benefits, and therefore the 
rule is arbitrary and capricious and/or is in tension with the prudent 
operator standard. The BLM disagrees. The RIA for the final rule 
provides estimates of the monetized costs and benefits under the 
accounting rules in OMB Circular A-4, p.38 (2003), and acknowledges 
that not all costs and benefits can be monetized. Comparison of 
monetized benefits to monetized costs provides useful but not complete 
analysis, and thus is not determinative with respect to the non-
statutory prudent operator standard. The final rule requires operators 
to incur some expenses from which they may derive revenue (selling the 
gas), or may not gain revenue (paying royalties on flared gas or 
curtailing oil production to limit flaring). For example, the RIA 
treats royalties as ``transfer payments.'' Transfer payments do not 
increase or decrease the wealth of society as a whole, and thus are not 
counted as benefits of the final rule under the OMB Circular. For the 
Federal taxpayers and Indian mineral owners, though, royalty payments 
are income, and as such are benefits to which they are entitled under 
statute, regulations, and the terms of leases. We also note that some 
industry commenters point out that some of the costs of the proposed 
rule projected in the draft RIA are for tasks that are already required 
by the EPA in New Source Performance Standards subpart OOOOa. The BLM 
acknowledges that some projected costs are for tasks now required in 
the final EPA New Source Performance Standards subparts OOOOa, OOOOb, 
and OOOOc rules, as addressed in the RIA.
Comments on Banning Routine Flaring and Requiring Gas Capture
    Summary of Comments: Some commenters requested that the BLM's final 
rule include a prohibition on ``routine flaring'' and that the final 
rule should ``require capture of flared gas where it is both 
technologically and economically feasible.'' The commenters also assert 
that the BLM is ``legally required to reduce waste, not just charge 
royalties on it.'' They note that reducing the waste of avoidably lost 
gas through capture requirements will also benefit ``individual 
taxpayers and Tribes and will have the added co-benefits of protecting 
frontline communities and the climate from the effects of wasted gas.'' 
Some commenters specifically noted the impacts of oil and gas 
operations and venting and flaring on environmental justice communities 
and asserted that charging royalties on flaring of associated gas and 
requiring WMPs will not significantly reduce venting and flaring 
without a prohibition on routine flaring.
    Response: The BLM disagrees with those commenters in part. The MLA 
does not mandate capture of all gas as such or place a ban on venting 
or flaring as such, but instead requires operators to ``use all 
reasonable diligence to prevent the waste of oil or gas developed in 
the land.'' \135\ As commenters note, the MLA also requires that all 
leases include ``a provision that such rules for . . . the prevention 
of undue waste as may be prescribed by said Secretary shall be 
observed.'' \136\ Those statutory provisions accommodate instances 
where waste is not preventable, even when operators employ all 
reasonable diligence. Likewise, section 50263 of the IRA does not 
mandate capture of gas or place a ban on venting or flaring as such, 
but instead requires, subject to exceptions, the payment of royalties 
on gas that is consumed or lost by venting, flaring, or negligent 
releases through any equipment during upstream operations.\137\ In 
short, Congress could have banned venting and flaring as such in the 
MLA or IRA, but did not.

U.S.C. 1727.
---------------------------------------------------------------------------

    The final rule implements the requirement in section 50263 of the 
IRA to assess royalties on gas that is lost by venting and flaring. 
Although the BLM believes that the royalty obligation for flared gas 
provides some marginal incentive for operators to make investments to 
sell the gas rather than to pay royalties on flared gas, we agree with 
the commenters that the statutory requirement for operators to use all 
reasonable diligence to prevent waste is a separate though related 
mandate--one that the final rule achieves through such requirements as 
a WMP.
    Some commenters assert that to meet the MLA's requirements, the BLM 
must: (1) adopt a definition of ``unreasonable and undue waste'' that 
clarifies that routine flaring constitutes avoidable loss; (2) ban 
routine flaring, as some States have done; and (3) include only narrow 
exceptions where there is no alternative to venting or flaring. The BLM 
agrees that much of the historical flaring was avoidable, and as 
discussed below, the final rule includes provisions that impose limits 
on what would otherwise be ``routine flaring,'' including the 
definition of ``unavoidably lost'' in Sec.  3179.41(b). We disagree, 
though, that the MLA requires that all routine flaring be defined as 
``avoidable'' loss. The MLA requires operators to use ``reasonable 
diligence'' to avoid waste, and thus ``reasonable diligence'' to 
prevent undue waste; the statute does not prohibit all venting and 
flaring. Contrary at least one commenter's views, therefore, the final 
rule is not based on maximizing operators' internal profit--that is not 
the

[[Page 25399]]

test for ``reasonable diligence,'' and the final rule may require some 
operators to incur some costs of compliance. Other operators may design 
and operate their facilities to capture and sell virtually all oil-well 
gas at a profit, but that is merely sufficient--not necessary--for 
compliance with the relevant portions of the rule. Although the MLA 
does not authorize the BLM to prohibit all flaring, State laws or 
regulations prohibiting routine flaring apply to operations on Federal 
lands.
    Some commenters argue that FLPMA requires the BLM to protect the 
quality of the air and atmospheric resources, citing 43 U.S.C. 
1701(a)(8). Section 1701(a)(8) states it is the ``policy of the United 
States'' that ``the public lands be managed in a manner that will 
protect the quality of [various ecologic values, including] air and 
atmospheric'' values. That statement, however, is ``effective only as 
specific statutory authority for [its] implementation is enacted by 
[FLPMA] or by subsequent legislation and shall then be construed as 
supplemental to and not in derogation of the purposes for which public 
lands are administered under other provisions of law.'' \138\ Here, the 
BLM's authority for its waste prevention and safety measures is 
established in the MLA, FOGRMA, and the IRA. The purposes of the final 
rule are waste prevention and royalty accountability, not air quality 
control. The BLM also addresses impacts on air quality in the EA for 
the final rule, as required by statute.
---------------------------------------------------------------------------

    \138\ 43 U.S.C. 1701(b).
---------------------------------------------------------------------------

    Commenters cited evidence that continued fossil fuel production is 
inconsistent with meeting goals of limiting climate change and that 
communities living near oil and gas operations suffer 
disproportionately high rates of adverse health effects. Those include 
several environmental justice communities near oil and gas operations 
on the public lands. Those issues are discussed in the NEPA compliance 
document and the RIA. However, ending fossil fuel production is outside 
the scope of this rulemaking, the purpose of which is to update the 
waste prevention requirements for oil and gas development on public 
lands. Like several other oil and gas regulations, the final rule may 
have some incidental public health and climate effects, but the BLM 
does not have authority to regulate air emissions for the benefit of 
public health or the climate, and the final rule is designed to address 
waste prevention and royalty accountability.
    A commenter advocated greater enforcement by the BLM. The BLM 
regularly reviews its enforcement programs for effective deployment of 
its resources. Enforcement plans, however, are outside the scope of 
this rulemaking.
    A commenter asserted that the BLM underestimated historical venting 
and flaring. The BLM has used the best available data. That data show 
that the current regulation at NTL-4A has failed to control venting and 
flaring, particularly over the last two decades. Thus, we agree with 
the commenter that a more effective regulation is needed to assure that 
operators exercise reasonable diligence to prevent waste.
    The BLM also recognizes the benefits of gas capture, and the final 
rule encourages greater capture and sale of gas from oil wells. In part 
in response to these comments, the BLM included in Sec.  3162.3-1 of 
the final rule an option for operators to self-certify that they will 
capture 100 percent of oil-well gas produced by an oil well as an 
alternative to submitting a waste management plan. If a self-certifying 
operator flares gas other than in response to a defined emergency, the 
loss is ``avoidable'' and fully royalty bearing. Although the BLM has 
no firm estimates for the number of operators who will self-certify, 
the option should both prevent waste and prove attractive for the 
reasons set forth elsewhere in this preamble.
Comments on Impact of the Rule on Indian Leases
    Summary of Comments: Noting that the proposed rule was generally 
intended to apply in equal measure to Federal leases and Indian leases, 
one commenter criticized the rule for not addressing how flaring 
limitations and other features of the rule--given their potential to 
cause premature shut[hyphen]in or curtailment of oil and gas 
production--may disproportionately impact Indian lessors who rely on 
production revenues and may not be as willing as the Federal Government 
to curtail or shut[hyphen]in production in order to avoid what the 
commenter characterized as ``relatively minor'' losses of revenue 
resulting from venting or flaring. The commenter also contended that, 
under the various Indian leasing statutes--including the IMDA (25 
U.S.C. 2101 et seq.)--the BLM must assure that the lands are developed 
in a manner that maximizes the ``best economic interests'' of Indian 
lessors.
    Response: The BLM's regulations apply to oil and gas operations on 
Indian trust and restricted fee lands as provided by 25 CFR 221.1(c), 
212.1(d), 225.1(c), and the BLM is the bureau tasked with regulating 
oil and gas operations on those lands by delegations to the BLM from 
the Secretary of the Interior. The purposes of the regulations of 
mineral development on Indian lands are to maximize the best economic 
interest of the Indian mineral owner and to minimize any adverse 
environmental or cultural impact. 25 CFR 221.1(a) (Tribal leases), 
212.1(a) (allotted leases), 225.1(a) (IMDA). ``In considering whether 
it is `in the best interest of the Indian mineral owner' to take a 
certain action . . . , the Secretary shall consider any relevant 
factor, including, but not limited to: economic considerations, such as 
date of lease expiration; probable financial effect on the Indian 
mineral owner; leasability of land concerned; need for change in the 
terms of the existing lease; marketability; and potential 
environmental, social, and cultural effects.'' 25 CFR 211.3, 212.3, 
225.3. Accord, e.g., 25 U.S.C. 2103(b) (IMDA). Thus, economic 
considerations, such as immediate production of oil, are relevant 
factors, but they are not the sole factors; the regulations promulgated 
in accordance with the BLM's statutory authority give the Secretary 
broad discretion. The Secretary thus has discretion to require 
operators producing Indian oil to take reasonable measures to reduce 
waste of Indian resources, to define avoidably lost gas, and to require 
payment of royalties to the Indian lessors on avoidably wasted gas.
    Since the final rule will apply equally on Indian lands as it does 
on Federal lands, there will be no disproportionate impact on Indian 
leasing or development. It might be that on some leases at some times, 
Indian royalty payments would temporarily decrease as oil production is 
curtailed while the operator complies with the final rule. We have no 
reason to believe that total long-term revenues from such leases would 
suffer, rather we believe they will increase as the operators pay 
royalties on the gas as well as on the oil. Indeed, for many leases 
there is likely to be no decrease in royalty payments, and most likely 
there will be increases in royalty payments because operators will pay 
royalties on captured or flared gas with little or no interruption of 
oil sales.
    We do not believe that the final rule will cause premature plugging 
and abandonment of otherwise profitable wells. Every day, oil wells on 
Indian lands, as on Federal lands and elsewhere, are produced at 
capacity, curtailed, shut in, or plugged and abandoned based on a 
variety of factors, including production quantity and quality, costs of 
production, availability of transportation, and commodity prices. 
Although it is possible that

[[Page 25400]]

compliance with the final rule may increase net costs for some 
operators, it would be only one of many business costs for operators 
and is likely not as determinative for continuing operations as are the 
changes in prices for the oil or gas, either positive or negative. 
There is nothing improper in the final rule's requirements to reduce 
waste of Indian gas and to pay royalties to the Indian mineral owners 
on gas that would otherwise be wasted. The final rule has not been 
changed in response to the comment.
Comments on the RIA
    In preparing the final rule, the BLM updated the numbers in the 
proposed RIA. The updated RIA indicates that the final rule would cost 
$19.3 million per year (using a 7 percent discount rate to annualize 
capital costs), while generating private costs savings benefits of 
around $1.8 million per year and ancillary effects on society from 
reduced methane emissions of around $17.9 million per year, with total 
benefits averaging around $19.7 million per year. The updated RIA 
estimates that the final rule would generate $51 million per year in 
royalties. The projected costs changed from the RIA for the proposed 
rule to the RIA for the final rule because the final rule does not 
include certain requirements from the proposed rule, such as pneumatic 
control devices, thereby reducing the rule's costs.
    The BLM received a comment stating that the BLM's estimated burden 
hours for operators to prepare a WMP was too low. In response, the BLM 
notes that there are significantly fewer requirements for a WMP in the 
final rule as compared with the proposed rule. Therefore, we believe 
that our estimate of 1 hour is appropriate.
    One commenter disagreed with the BLM's estimate regarding the 
projected number of orifice meters that would be installed the first 
year. The intent of the comment is not entirely clear because it only 
indicates the commenter's view that an estimated installation of 968 
meters appears to be inaccurate but does not specify the nature of the 
inaccuracy or how the inaccuracy is a burden to operators. In the final 
RIA, the BLM estimates that there would be a total of 902 meters 
installed and explains that it uses the 1,050 Mcf threshold to 
determine the number of meters installed because the final rule 
requires all high-pressure flares with more than 1,050 Mcf of flaring 
per month to measure flaring.
    The BLM received a comment expressing concern with the 
administrative burden resulting from the proposed rule. The BLM 
addresses administrative burdens in the RIA and the accompanying 
supporting statement under the Paperwork Reduction Act. In the RIA for 
the final rule, the BLM estimates that the total annual administrative 
burden of the final rule will be about $8.9 million. The BLM notes that 
the requirements for a WMP have been significantly reduced in the final 
rule. In the final rule, the WMP only requires information operators 
would have readily available when submitting an APD. The information 
collection activity associated with the WMP required for this rule is 1 
hour of additional time to complete an APD. Further, operators have the 
option of self-certifying that they will commit to capture 100 percent 
of the gas and thus avoid the administrative cost of preparing a WMP. 
The information collection activity associated with either preparing 
and submitting the WMP or the self-certification is 1 hour of 
administrative time. The BLM believes operators submitting APDs for 
multiple wells on a single well pad will be able to simply copy and 
paste the WMP from one well's APD into the next well's APD. This 
copying and pasting for a multi-well pad also has an information 
collection burden of 1 hour, which most likely overestimates the time 
it will take operators to copy and paste the information from one 
document into another. And the final rule does not require ``complete 
and adequate'' information in a WMP as proposed, but does require the 
WMP to be technically and administratively complete. The phrase 
``technically and administratively complete'' is further explained in 
the preamble discussion for Sec.  3162.3-1.

A. 43 CFR Part 3160--Onshore Oil and Gas Operations

Section 3162.3-1 Drilling Applications and Plans
    Existing Sec.  3162.3-1 contains the BLM's longstanding requirement 
for the operator to submit an APD prior to conducting any drilling 
operations on a Federal or Indian oil and gas lease. Drilling may only 
commence following the BLM's approval of the APD. The proposed rule 
would have added two new paragraphs to Sec.  3162.3-1, intended to help 
operators and the BLM avoid situations where substantial volumes of 
associated gas are flared from oil wells due to inadequate gas capture 
infrastructure.
    Proposed Sec.  3162.3-1(j) would have required an operator to 
provide a WMP with its APD for an oil well, demonstrating how the 
operator intended to address the capture of associated gas from an oil 
well when production begins. The purpose of the proposed WMP was to 
help the BLM understand how much associated gas could be wasted as a 
result of the approval of an APD. The proposed WMP required the 
inclusion of the following information with an oil-well APD: the 
anticipated completion date of the oil well; a description of the 
anticipated production of both oil and associated gas; a certification 
that the operator has informed at least one midstream processing 
company of the operator's production plans; and information regarding 
the gas pipeline to which the operator plans to connect. If an operator 
was not able to identify a gas pipeline with sufficient capacity to 
accommodate the anticipated associated gas production, the WMP would 
have been required to also include the following information: a gas 
pipeline system map showing the existing pipelines within 20 miles of 
the well and the location of the closest gas processing plant; 
information about the operator's flaring from other wells in the 
vicinity; and a detailed evaluation of opportunities for alternative 
on-site capture methods, such as compression of the gas, removal of 
Natural Gas Liquids (NGL), or other capture means. Finally, the 
operator would have been required to include any other information 
demonstrating the operator's plans to avoid the waste of gas production 
from any source, including pneumatic equipment, storage tanks, and 
leaks.
    The purpose of the proposed WMP was for the operator to provide the 
BLM with information necessary to understand how much associated gas 
would be lost to flaring if the BLM were to approve the oil-well APD 
and whether the loss of that gas would be reasonable under the 
circumstances. If the WMP were to demonstrate that approving an 
otherwise administratively and technically complete APD could result in 
undue waste of Federal or Indian gas, the proposed Sec.  3162.3-1(k) 
would have authorized the BLM to take one of the following actions: the 
BLM could have approved the APD subject to conditions for gas capture 
and/or royalty payments on vented and flared gas; or the BLM could have 
deferred action on the APD in the interest of preventing waste. If the 
potential for undue waste had not been addressed within 2 years of the 
applicant's receipt of the notice of the deferred action, under the 
proposed rule the BLM would have denied the APD.
    The BLM received numerous comments on the proposed WMP. Based on 
those comments, we believe there was some confusion about when a WMP 
would be required. For both the proposed and final rules, a WMP is 
required when a Federal or Indian APD is required. In both the proposed 
and final rules, only wells that are being drilled to target oil 
production--in other words Federal or Indian oil-well APDs--will 
require a WMP. The BLM assumes that if an operator is drilling a gas 
well, there is a predetermined market for the gas or a plan to shut in 
wells until gas infrastructure is built. For this reason, if a well is 
being drilled to a known gas formation and will be producing primarily 
gas, the Federal or Indian APD does not require a WMP.
    Based on public comment, the BLM has revised the content of the 
proposed WMP in this final rule. Many commenters said the waste 
minimization requirements were overly burdensome for both the BLM and 
operators. In addition, commenters read the requirements as calling for 
operators to provide proprietary, confidential information belonging to 
midstream companies that operators are unable to provide. Commenters 
were also concerned about how the BLM would evaluate an operator's WMP, 
pointing to subjective language in proposed Sec.  3162.3-1(j) 
indicating that the BLM could deny an APD if the operator failed to 
submit a complete and ``adequate'' WMP. Many commenters said the 
proposed required information for the WMP failed to meet the BLM's 
stated objectives of understanding associated

[[Page 25402]]

gas capture and reducing waste through flaring prior to approval of a 
Federal or Indian APD.
    After evaluating the primary objective of the WMP, which is to 
ensure operators have adequately planned to reduce associated gas waste 
prior to drilling an oil well, the BLM agrees with commenters that the 
rule can be effective without requiring all the information in the 
proposed rule. The proposed rule required 19 pieces of information for 
the WMP for the operator to demonstrate to the BLM that it had 
sufficiently planned for the capture or sale of associated gas from an 
oil well. After careful consideration of the comments and the purpose 
of a WMP, the BLM in the final rule is reducing the information 
required to 4 pieces in a WMP: (1) initial oil production estimates and 
decline, (2) initial gas production estimates and decline, (3) 
certification that the operator has an executed gas sales contract to 
sell 100 percent of the produced oil-well gas, and (4) any other 
information demonstrating the operator's plans to avoid the waste of 
gas.
    The BLM agrees with the commenters that BLM's objective--
determining if an operator has a plan to capture the produced gas--can 
be accomplished with less information. And as mentioned above, the BLM 
intends to eschew collection of information that could be proprietary 
or confidential. The final rule also provides operators with an 
alternative to the submission of a WMP with their APDs by allowing 
operators to instead submit a self-certification statement that the 
operator will be able to capture, as defined in final Sec.  3179.10, 
100 percent of the oil-well gas that the oil well produces.
    The BLM has required the anticipated initial production rate and 3 
years of production decline because the BLM has concluded that 3 years 
of data will sufficiently cover the ordinarily steep decline for 
production for unconventional reservoirs and the associated 
establishment of the reservoir's production decline curve. This 
information provides the BLM with an estimate of how much associated 
gas could be flared, the size of production equipment required at 
initial production, and the size of production equipment required when 
production has leveled off. The WMP information is relevant to 
understand not only the volume at risk for flaring, but also how the 
sizing of the production equipment affects tank vapors. (If the 
production equipment is undersized or there is insufficient separation 
upstream of the production tanks, there will be more gas wasted as tank 
vapors.) Approved APDs with a WMP will be subject to the flaring 
limitations identified in final Sec.  3179.70 once the well begins 
producing. The BLM believes the revised waste minimization requirements 
reduce the burden on operators, reduce the review time for the BLM, 
eliminate any concern of providing proprietary or confidential 
information, and increase the BLM's understanding of the disposition of 
the associated gas from an oil well to ensure the public receives a 
fair return for its oil and gas.
    As an alternative to the submission of a WMP with the APD, Sec.  
3162.3-1(d)(4) of the final rule allows operators to submit a self-
certification. Section 3162.3-1(k) provides that a self-certification 
is a statement by the operator that it will be able to capture, as 
defined in final Sec.  3179.10, 100 percent of the oil-well gas that 
the oil well produces. If the operator elects to self-certify, all 
flared oil-well gas, except for gas flared under emergencies as 
identified in Sec.  3179.83, is an avoidable loss with a royalty 
obligation and is not subject to the unavoidable loss threshold in 
Sec.  3179.70(a). In the case of self-certification, 100 percent of the 
oil-well non-emergency flared gas has a royalty obligation from the 
date of first production until the well is plugged and abandoned. The 
BLM offers the self-certification alternative to accommodate operators 
who may consider this option an advantageous business alternative while 
ensuring the public receives a fair return for its oil and gas. An 
operator might choose to avoid having to submit a WMP because it can be 
relatively easy to design, build, and operate its facilities to capture 
all of the gas and sell it. In addition, an operator may want to 
accelerate drilling and development in lieu of waiting for a gas 
contract and accept the additional royalty obligation as a business 
expense should the operator need to flare following drilling and 
completion.
    The BLM's approval process for the WMP or the self-certification 
statement appears in the new final Sec.  3162.3-1(l). With this 
addition, the BLM has clarified for operators how the Bureau will 
evaluate a WMP or self-certification statement. Upon review of the WMP 
or the self-certification, the BLM may take one of the following 
actions: (1) approve an administratively and technically complete oil-
well APD with a WMP, subject to the conditions for flared gas described 
in Sec.  3162.3-1(j); (2) approve an administratively and technically 
complete oil-well APD with a self-certification statement for 
associated gas capture subject to the conditions for flared gas 
described in Sec.  3162.3-1(k); or (3) defer action on an APD that is 
not administratively or technically complete in the interest of 
preventing waste until such time as the operator is able to amend its 
APD to comply with the requirements in either Sec.  3162.3-1 paragraph 
(j) or (k).
    The final rule replaces the subjective term ``adequate'' in this 
section with the term ``administratively and technically complete.'' 
The concept ``administratively and technically complete'' appears in 
the original Sec.  3162.3-1(d), which states that ``[p]rior to 
approval, the application shall be administratively and technically 
complete.'' To be administratively complete, an APD must contain all 
the required components: a drilling plan, a surface use plan of 
operations, evidence of bond coverage, other information as may be 
required by applicable orders and notices, and, with the finalization 
of this rule, for an oil well, a WMP or self-certification. For an APD 
to be technically complete, the APD must fulfill all the requirements 
of each of the components and be technically correct pursuant to any 
applicable orders and notices. For example, an APD is not 
administratively complete if it does not include a drilling plan. If 
the APD does include a drilling plan, but the drilling plan fails to 
include the appropriate blowout prevention equipment, as required in 43 
CFR subpart 3172, then the drilling plan is not technically complete.
    A WMP or self-certification will now be a required component of an 
APD for it to be administratively complete. If an operator does not 
submit a WMP or a self-certification statement with the APD, then the 
APD will not be administratively complete. For the WMP or self-
certification to be technically complete, it must contain the required 
information in final Sec.  3162.3-1 paragraph (j) or (k). If the 
operator submits a WMP that includes only the anticipated oil 
production decline curve for 1 year, then the APD is not technically 
complete. If an operator fails to include a WMP or self-certification 
as required or if the WMP or self-certification fails to meet the 
requirements in Sec.  3162.3-1 paragraph (j) or (k), then the BLM will 
defer action on the APD until the operator amends the APD to comply 
with the requirements of administrative and technical completeness.
    Final Sec.  3162.3-1(l)(3) limits the time in which the operator 
must address deficiencies in the WMP or the self-certification to 
within 2 years of submission of the APD. If the operator does not meet 
this deadline, then the

[[Page 25403]]

BLM may disapprove the APD. This change conforms the WMP or self-
certification process with the rest of the current Sec.  3162.3-1 and 
review process. Furthermore, a 2-year limit provides operators with 
sufficient time to either secure a gas sales contract or proceed with 
self-certification in the absence of a sales contract. The 2-year time 
limit also ensures that an APD will not remain in a pending status with 
the BLM for an extended period because of an operator's lack of 
diligence or inability to complete its application. A 2-year limit is 
reasonable for an operator who intends to drill on a lease and is 
capable of submitting a complete WMP or self-certification.

B. 43 CFR Part 3170--Onshore Oil and Gas Production

Section 3179.1 Purpose
    Final Sec.  3179.1 has only one change from the proposed rule. The 
BLM changed the name of the Osage Tribe to the Tribe's official name, 
The Osage Nation, which the Tribe adopted in 2008. The purpose of 
subpart 3179 remains unchanged in the final rule and continues to 
implement and carry out the purposes of statutes relating to the 
prevention of waste from Federal and Indian oil and gas leases, 
conservation of surface resources, and management of the public lands 
for multiple use and sustained yield, including section 50263 of the 
IRA.
    This final rule section continues to clarify that upon publication, 
final subpart 3179 supersedes those portions of NTL-4A that pertain to, 
among other things, flaring and venting of produced gas, unavoidably 
and avoidably lot gas, and waste prevention. Subpart 3178, published on 
November 18, 2016 (81 FR 83078), superseded the portions of NTL-4A that 
pertain to oil or gas used on lease for beneficial purposes (see 43 CFR 
subpart 3178). With the final publication of subpart 3179, NTL-4A has 
been superseded in its entirety.
Section 3179.2 Scope
    Section 3179.2 of the final rule continues to identify the 
operations to which the various provisions of subpart 3179 will apply. 
Paragraph (a) states that, in general, the provisions of the final rule 
apply to: (1) all onshore Federal and Indian (other than The Osage 
Nation) oil and gas leases, units, and communitized areas; (2) IMDA 
agreements, except in certain circumstances described in the rule text; 
(3) leases and other business agreements and contracts for the 
development of Tribal energy resources under a Tribal Energy Resource 
Agreement entered into with the Secretary, except under certain 
circumstances; and (4) wells, equipment, and operations on State or 
private tracts that are committed to a federally approved unit or CA. 
Final Sec.  3179.2(a) removes the duplication of the words ``provided 
in'' that appeared in the proposed rule.
    Final paragraph (b) is substantially the same as proposed paragraph 
(b). The only change in the final rule is that the crossed-referenced 
sections have been revised to reflect the new section numbers. As in 
the proposed rule, it provides that certain provisions in subpart 3179, 
namely redesignated Sec. Sec.  3179.50, 3179.90, and 3179.100 through 
102, apply only to operations and production equipment located on a 
Federal or Indian oil and gas surface estate and do not apply to 
operations on State or private tracts, even where such tracts are 
committed to a federally approved unit or CA, sometimes referred to as 
``mixed ownership'' agreements.
    As in the proposed rule, final Sec.  3179.2(b) implicates a 
question regarding the BLM's authority raised by the court that vacated 
the 2016 Waste Prevention Rule. That court stated that the MLA ``does 
not provide broad authorization for the BLM to impose comprehensive 
Federal regulations similar to those applicable to operations on 
Federal lands on State or privately-owned tracts or interests.'' \139\ 
In that court's view, the BLM's authority to regulate unit or CA 
operations on State and private tracts under the MLA and FOGRMA may be 
limited to rates of development and matters directly relevant to the 
BLM's proprietary interest in the Federal minerals.\140\ This rule does 
not reach a position on the full extent of the BLM's authority to 
regulate non-Federal lands. For purposes of this rule, however, we note 
that many provisions in the final rule--including final Sec. Sec.  
3179.41, 3179.70, 3179.81, 3179.82, and 3179.83 and the final 
measurement and reporting requirements in final Sec. Sec.  3179.71 and 
3179.72--have a direct impact on royalty revenue and apply to all 
operations producing Federal or Indian gas, whether on a Federal or 
Indian lease or as part of a mixed-ownership agreement. Other 
requirements--such as those related to storage tank hatches and the 
leak detection-and repair program--apply when the facilities are 
located on Federal or Indian surface estate because those requirements 
have a slightly less direct connection to royalties. While the BLM does 
not view that connection as dispositive of its authority in this 
sphere, it has in this rule chosen to limit application of these 
programs in light of the BLM's recent history of regulation and the 
possibility that further extending these requirements would generate 
relatively small marginal gains in revenue relative to other 
requirements.

    The final rule redesignates sections throughout the subpart to 
standardize the organization of sections in part 3170 (e.g., section 
numbers ending in ``30'' will be the sections that contain 
incorporation-by-reference material, as required, throughout part 
3170). Further, the reorganization of the sections in part 3170 groups 
similar topics together under similar section designations for ease of 
use and readability.
Section 3179.10 Definitions and Acronyms
    This final rule section contains definitions for 12 terms that are 
used in subpart 3179 as opposed to the 13 terms that appeared in the 
proposed rule. The BLM removed the proposed definition for ``storage 
vessel.'' Proposed Sec.  3179.203, which pertained to oil storage 
vessels, was significantly revised based on public comment as discussed 
further below. Thus, the BLM removed the definition for ``storage 
vessel'' and substituted the more commonly understood term ``oil 
storage tank'' for ``storage vessel'' in the remainder of subpart 3179. 
The use of the common term ``oil storage tank'' brings the final 
subpart 3179 into alignment with the use of ``oil storage tank'' in 
current subpart 3174.
    One commenter recommended that, ``for the purposes of this section, 
where there is a State definition that applies for the same BLM term, 
the BLM will apply the definition used in the State in which the 
applicable gas or oil well is located.'' The BLM is charged with 
ensuring that the public and Indian mineral interests receive a fair 
return for their oil and gas leases. That obligation necessarily 
entails the determination of a lessee's royalty obligation, which, in 
the case of waste prevention, relies directly on the BLM's consistent 
use of terms. The BLM would be unable to implement the requirements of 
this rule consistently--and to ensure a uniformly fair return--if the 
Bureau were to rely on multiple, varying, and changeable State 
definitions for the terms used in this regulation. Further, if the BLM 
were to adopt this approach, and there was a conflict between the BLM 
requirements and the State definition, there would be no clear path to 
resolution of the conflict. The BLM did not make changes

[[Page 25404]]

to allow for the use of definitions from State code to apply to Federal 
and Indian oil and gas regulations for the State in which the 
production occurs.
    The BLM received comments on the definition for ``automatic 
ignition system'' that agree with the BLM's approach to not require a 
specific type of device. The BLM agrees that the term ``automatic 
ignition system'' connotes the concept of an ignition source without 
specifying a particular type of device. To be clear, any applicable 
rule of the EPA, a State, or a Tribe regarding such equipment and its 
destruction efficiency apply to operations regulated by the BLM.
    One commenter stated that requiring a continuous flame is wasteful 
and unnecessary. The BLM disagrees with this comment because the 
proposed definition of ``automatic ignition system'' only requires a 
continuous pilot flare where needed to ensure continuous combustion. 
The BLM believes the proposed definition allows for a great deal of 
operator flexibility and did not change the ``automatic ignition 
system'' definition based on the comments.
    The BLM did not receive any comments on the proposed definitions 
for ``capture,'' ``compressor station,'' ``gas-to-oil ratio (GOR),'' or 
``pneumatic controller.'' Therefore, these four definitions remain the 
same in final rule as in the proposed rule.
    One commenter requested the BLM to add a definition for ``economic 
feasibility.'' The commenter's recommended definition mirrors part of 
the definition for ``economically marginal property'' found in subpart 
3173. For the proposed rule, the BLM used the term ``economically 
infeasible'' in proposed Sec.  3179.203(b), which addressed vapor 
recovery systems. Since the BLM has removed the requirement for a vapor 
recovery system on oil storage tanks in the final rule, the final rule 
no longer references the terms ``economically feasible'' or 
``economically infeasible.'' Therefore, the BLM has not included a 
definition for ``economic feasibility'' in the final rule.
    Commenters recommended that the BLM include a definition for the 
term ``exploratory well.'' The BLM has a definition for ``exploratory 
well'' in existing subpart 3172, but that definition applies within 
that subpart. Leaving the term undefined in this rule could cause 
confusion. Accordingly, we are adding the same definition of 
``exploratory well'' to this rule as appears in 43 CFR 3172.5: 
``[e]xploratory well means any well drilled beyond the known producing 
limits of a pool.'' Subpart 3179 resides in part 3170 Onshore Oil and 
Gas Production. The definitions that are used within multiple subparts 
of part 3170 reside in subpart 3170. Originally published in 1988 as 
Onshore Oil and Gas Order No. 2, subpart 3172 was codified in the CFR 
on June 16, 2023 (88 FR 39514). When the BLM revises subpart 3170, it 
will remove the definition for exploratory well from subpart 3172 and 
include it in subpart 3170 since the definition now applies to more 
than one subpart.
    The BLM received numerous comments on the definition for ``gas 
well.'' The definition that the BLM included in the proposed rule was 
taken from the Conservation Division Manual 644.5. One commenter 
recommended including a definition that relied on a GOR standard 
throughout the rule and did not recommend incorporating any deference 
to the States' definitions in the rule. The commenter did not provide 
any recommendation for the appropriate GOR standard for a gas well. The 
BLM is aware that many States define a gas well in terms of GOR, and 
the GOR varies among State definitions. The BLM has decided not to 
change the proposed definition, which relies on whether the well 
produces more energy from gas or oil. The BLM has implemented that 
definition in the CDM for decades. Commenters did not explain how a GOR 
based definition would improve implementation of this final rule. 
Conversely, adopting a new definition--one relying on GOR--could create 
implementation conflicts insofar as the BLM chooses a GOR that differs 
from certain State definitions. Historically, the proposed
