The Federal Role in Orphan Oil and Gas Well Reclamation

Production of oil and gas in the United States began in the
late 19th century and continues to contribute to meeting U.S.
fuel and petrochemical demands. Over time, federal and
state requirements were put in place to manage such aspects
of oil and gas development as siting, safety, emissions, and
reclamation. Prior to federal and state regulations, many oil
and gas wells were orphaned, or left unreclaimed. In
many cases, particularly for early oil and gas development,
little is known about the status, location, and depth of those
wells. Additionally, more recent oil and gas wells,
operating subject to federal or state regulation, could
become orphaned if a well operator is unwilling or
financially unable to complete reclamation of a well site
that has ceased production operations. The federal role in
reclaiming orphan oil and gas wells has been limited to
wells located on federal lands. In the 117th Congress, the
Infrastructure Investment and Jobs Act (IIJA; P.L. 117-58)
expanded the federal role in reclaiming orphan oil and gas
wells by increasing funding for the federal reclamation
program and establishing a grant program to assist state and
tribal orphan well programs. This In Focus discusses the
federal and state roles in permitting wells, background of
orphan oil and gas wells, potential environmental impacts,
and related provisions in the IIJA.
Federal and State Roles in Permitting Oil
and Gas Wells
The scope of regulations that govern oil and gas well
operations may vary from one operation to another
depending on the applicability of federal, state, or local
regulations to specific activities, and the regulatory
jurisdiction in which an operation is located. Congress has
not authorized nationwide federal requirements for
permitting and reclaiming oil and gas wells. Under current
law, the federal role for permitting oil and gas wells or
reclaiming orphan wells is generally limited to those on
federal lands. The Bureau of Land Management (BLM) of
the U.S. Department of the Interior (DOI) is the principal
permitting agency for oil and gas production operations on
federal onshore lands pursuant to the Mineral Leasing Act
of 1920, as amended, and certain other authorities. The
scope of reclamation of oil and gas wells in the regulations
includes plugging and capping the well, as well as
reclaiming any equipment and land disturbances at the site
resulting from the production operations. On nonfederal
lands, a state or tribe would be primarily responsible for
permitting oil and gas wells or reclaiming orphan wells
within their respective jurisdictions under their own laws,
regulations, and programs. Compliance with federal and
state regulatory requirements is enforced mostly through
permits. Performing oil and gas operations without the
requisite permits is unlawful and may be subject to
enforcement by federal or state regulators, depending on
their respective jurisdictions. There is no singular permit

issued at the federal or state level that governs all aspects of
an oil and gas operation. Other permits also may be
required to ensure compliance with other requirements that
govern particular facets of an operation, such as air quality
and water quality permits.
On federal lands, oil and gas operators are required to
provide a surface use plan prior to construction at the site to
identify how the site will be disturbed and reclaimed, as
part of the permit issued by BLM. Federal requirements for
oil and gas well sites may include capping the well, the
removal and disposal of equipment and wastes, the
regrading and contouring of the site, and revegetation of the
well pad and related disturbed lands. As part of a federal
permit, BLM requires an operator to provide a bond, or
financial assurance, which could be forfeited to BLM to
complete the reclamation if the operator does not complete
the reclamation requirements. In the event that the bond is
not sufficient, the ability of BLM to complete the site
reclamation would depend on its federal land management
authorities and funding. On nonfederal lands, state or tribal
reclamation and bonding requirements may vary or be
similar in scope and purpose to federal requirements,
depending on their respective laws and regulations.
Orphaned Wels Background
In general, oil and gas wells may become orphaned under
two differing sets of circumstances, depending on whether
the well operated prior to federal or state regulation. First,
operators of oil and gas wells may have left these sites
abandoned or unreclaimed years or decades prior to the
development of federal or state permitting and reclamation
requirements. Wells that operated prior to regulation
sometimes are referred to as legacy wells. As of 2016, the
U.S. Environmental Protection Agency (EPA) estimated the
total national inventory of orphan oil and gas wells was
3.11 million, but EPA noted other researchers have
estimated that the inventory of orphan wells ranged
between 2.1 million to 3.0 million at that time. Although
EPA has estimated the national inventory of orphan oil and
gas wells, the actual number, geographic location, and
condition of each well and well site may not be fully
understood. Because of the lack of information collected
prior to regulation, federal and state agencies have faced
challenges in estimating the numbers, locations, and
conditions of these legacy orphan wells within their
respective jurisdictions.
For more recent operations subject to federal or state
regulation, an oil and gas well could become orphaned if a
well operator does not complete the site reclamation
following production operations. In those instances,
completing the well site reclamation may become the
responsibility of the federal or state regulatory authority
