U.S. Department of the Interior: An Overview June 23, 2021 The U.S. Department of the Interior (DOI) is a federal executive department responsible for the administration of lands, minerals, and other resources of the United States. DOI Mark K. DeSantis for the conservation and administration of the public lands and mineral estate of the United States. DOI describes its mission as protecting and managing the nation'’s natural resources and Analyst in Natural cultural heritage for the benefit of the American people; providing scientific and Resources Policy scholarly information about those resources and natural hazards; and exercising the nation' nation’s trust responsibilities and special commitments to American Indians, Alaska Natives, and island territories under U.S. administration.

As part of its responsibilities, DOI oversees and fosters the use of more than 480 million acres of public lands, 700 million roughly 420 mil ion acres of federal lands, nearly 55 mil ion acres of tribal lands, more than 700 mil ion acres of subsurface minerals, and 1.7 billionabout 2.5 bil ion acres of the outer continental shelf. Each year, Congress deliberates legislation that could affect DOI'’s management of this vast federal estate. As a result, understandingUnderstanding the roles and responsibilities of DOI'’s various componentsagencies and offices iscan be valuable when crafting legislation that affects the department's operations and ability to fulfill its mission.

’s structure, operations, programs, and funding. DOI primarily implements its responsibilities and mission through nine technicalvarious bureaus that make up more than 80% 90% of the agency'’s workforce. These technical bureaus are the Bureau of Indian Affairs (BIA), Bureau of Indian Education (BIE), Bureau of Land Management (BLM), Bureau of Ocean Energy Management (BOEM), Bureau of Reclamation (Reclamation), Bureau of Safety and Environmental Enforcement (BSEE), National Park Service (NPS), Office of Surface Mining Reclamation and Enforcement (OSMRE), U.S. Fish and Wildlife Service (FWS), and U.S. Geological Survey (USGS). Each of these bureausbureau has a unique mission and set of responsibilities, as well as a distinctwel as an organizational structure that servesdesigned to meet its functional duties. In addition to these technical bureaus, DOI has multiple departmental offices, which that are responsible for other programs and provide leadership, coordination, and services to DOI'’s various bureaus and programs.

As of June 2018, DOI employed a staff of 69,563 nationwide across its bureaus and offices. However, total DOI employment figures fluctuate throughout the year, as some bureaus rely on seasonal and part-time staff, increasing staff totals during the summer months. The Office of Personnel Management (OPM) The names, structures, and responsibilities of DOI and its various bureaus and offices have evolved since the establishment of DOI in 1849. These changes and evolutions are regularly subject to congressional oversight and executive branch examination. In recent years, Congress has considered numerous executive branch proposals on DOI organization and management, including the transfer of programs between various agencies and offices, the creation of new offices and/or bureaus, and the consolidation of DOI boundaries across agencies. In December 2020, DOI employed a staff of 60,634 nationwide across its bureaus and offices, according to the Office of Personnel Management (OPM). DOI employment figures fluctuate throughout the year, in part because some bureaus increase seasonal and part-time staff during the summer months. OPM reports the average total DOI employment as 65,35063,175 for the four reporting periods from September 2017 to June 2018March 2020 to December 2020. The largest bureau within DOI based on number of staff is NPS, which averaged close to 20,000 staff over the same time period—more thannearly 19,000 employees during 2020—nearly twice the size of the second-largest bureau, BLM. The smallest technicalsmal est bureau by employment is OSMRE, which averaged just over 400 employees. Approximately 10% of all DOI staff are within the District of Columbia core-based statistical area (CBSA), which includes the District of Columbia and selected counties in Maryland, Virginia, and West Virginia.

Congress providesfewer than 400 employees. Congress provides discretionary appropriations for DOI through two annual appropriations bil s: the Interior, Environment, and Related Agencies bil and the Energy and Water Development and Related Agencies bil . From FY2017 to FY2021, total DOI appropriations increased 13% in current dollars. Enacted discretionary appropriations for FY2021 totaled $15.4 bil ion.

Enacted discretionary appropriations for FY2018 totaled $14.6 billion. DOI also received $566 million in supplemental emergency appropriations in FY2018, for a total of $15.2 billion in discretionary appropriations for FY2018.

The Department of the Interior (DOI) is a federal executive department responsible for the conservation and use of roughly three-quarters of U.S. public landsapproximately two-thirds of the estimated 640 mil ion acres of federal land. DOI defines its mission as to protect and manage the nation'’s natural resources and cultural heritage for the benefit of the American people; to provide scientific and scholarly information about those resources and natural hazards; and to exercise the country'’s trust responsibilities and special commitments to American Indians, Alaska Natives, and island territories under U.S. administration.¹ Initially 1 Initial y conceived as a "“home department"” in 1849 to oversee a broad array of internal affairs,²2 DOI has evolved to become the nation'’s principal land management agency, charged with administering the use of more than 480 million acres of public lands, 700 million roughly 420 mil ion acres of federal lands, nearly 55 mil ion acres of tribal lands, more than 700 mil ion acres of subsurface minerals, and 1.7 billionabout 2.5 bil ion acres of the outer continental shelf (OCS).³

Similarly, DOI'’s executive branch structure and operations are also thea subject of administrative scrutinyscrutiny and analysis by various Administrations. Over the course of the department'’s roughly 170-year history, DOI has evolved in response to the needs of the nation and at the behest of Congress and the President. (See (see Figure 1 for a timeline of selected events that influenced the current structure of the department)..) Some of these changes have been relatively broad in nature, such as the creation of a new agency or regulatory body. Other shiftschanges have been smallersmal er in scope, such as modifications to interagency processes or reorganizations in howreorganizations of resources or responsibilities are distributed among offices or programs.4 This report is a primer to understanding the organizational framework under which DOI operates, and it provides context for how ongoing and potential future reorganizations might affect these operations.

This report is a primer to understanding the organizational framework under which DOI operates, while providing context for how ongoing and proposed reorganizations might affect these operations. The report provides a timeline of congressional and executive actions that have shaped the structure and function of DOI since its establishment. It also offers a brief summary of DOI's history, mission, and current structure, as well as an overview of the primary functions of its multiple bureaus and offices as of December 2018. Employment figures and corresponding maps illustrate the varying regional office structures among DOI bureaus, as they exist currently. In addition, the report includes an overview of the annual funding and appropriations process for the department. Although the report provides a broad summary of the proposed reorganization efforts under way or in effect as of December 2018, it does not offer a detailed analysis of these plans or their potential impact on DOI's structure and function.

Establishment of the Department: A Brief History

Establishment of the Department: A Brief History Prior to the establishment of DOI in 1849, Congress apportioned domestic affairs in the United States across the three original executive departments: Department of State, Department of War (now Department of Defense), and Department of the Treasury.⁷6 The Department of State housed the nation'’s Patent Office, and the Department of War housed the Office of Indian Affairs and the Pension Office, which at the time administered pensions solely for military personnel.⁸ 7 Meanwhile, the General Land Office (GLO), which oversaw and disposed of the public domain, was placed by Congress within the Department of the Treasury because of the revenue generated by the GLO from land sales.⁹

8 By the 1840s, the growing federal estate acquired through the Louisiana Purchase, the Mexican-American War, and the newly negotiated Oregon Territory placed an increasing burden on the departments and their leadership.¹⁰9 In 1848, then-Secretary of the Treasury Robert J. Walker submitted to Congress a proposal that would bring together GLO, the Office of Indian Affairs, and several other disparate offices and functions under a single, separate executive department.¹¹ Congress officially10 Congress official y established the Department of the Interior on March 3, 1849.¹²

11 In addition to absorbing the functions of the Patent Office, the Office of Indian Affairs, the Pension Office, and GLO, the newly established DOI assumed responsibility for a wide range of other domestic matters. As part of DOI'’s organic legislation, Congress conferred on the Secretary of the Interior the "“supervisory and appellateappel ate powers"” held by the President over the commissioner of Public Buildings, as well wel as oversight responsibility for both the U.S. Census and the Penitentiary of the District of Columbia.¹³12 Over time, Congress further expanded the department'department’s functions to include the construction of the national capital'’s water system, the colonization of freed slaves in Haiti, water pollution control, and the regulation of interstate commerce.¹⁴13 Most of these early activities eventuallyeventual y were transferred from DOI'’s charge as Congress began to authorize and create new executive departments and independent agencies to handle this growing list of responsibilities.

Now, DOI hasBy the 20th century, DOI had evolved to focus primarily on protecting and managing natural resources,; conducting scientific research,; and exercising the nation'’s trust responsibilities to American Indians, Alaska Natives, and affiliated island communities. 6 T he Department of State (initially established as the Department of Foreign Affairs) was created in 1781 (1 Stat. 28). T he Department of War (1 Stat.49) and Department of the Treasury (1 Stat. 65) each were established eight years later, in 1789. 7 Utley and Mackintosh, Department of Everything Else. 8 T he General Land Office Act (2 Stat. 716), April 25, 1812, created the General Land Office (GLO) in the Department of the T reasury to “ superintend, execute, and perform, all such acts and things, touching or respecting the public lands of the United States,” including those functions formerly vested in the Secretaries of War and State. 9 John T .

Overview

DOI is a Cabinet-level department that employs approximately 6563,000 full-time employees across nine technical bureaus and various administrative and programmatic offices.¹⁵multiple bureaus and other offices.14 In addition to its headquarters in Washington, DC, DOI has staff in roughly 2,400 locations across the United States, including both regional offices and field centers.¹⁶locations.15 Each of DOI's technical ’s bureaus and programmatic offices has a unique mission and set of responsibilities, as well wel as a distinct organizational structure that serves to meet its functional duties.¹⁷. Figure 2 shows the DOI organization chart as of March 2021. Figure 2. DOI Organizational Chart of Bureaus and Selected Offices the DOI organization chart as of December 2018.

Additional information provided via personal communication between CRS and DOI Office of Legislative Affairs, April 27, 2021. Notes: Figure reflects DOI organizational chart as of this report; however, the organization and reporting status of bureaus and offices are subject to change and may be currently under review. The order of bureaus and offices is not intended to reflect a given hierarchy within DOI. CFO = Chief Financial Officer. The Assistant Secretary—Policy, Management and Budget serves as the DOI’s CFO. The FY2020 Interior Appropriations law approved the Administration’s proposal to establish the Bureau of Indian Education (BIE) as an independent bureau. See explanatory statement accompanying H.R. 1865 (enacted as P.L. 116-94) at House debate, Congressional Record, vol. 165, no. 204, book III (December 17, 2019), p. H11289. Congress now provides funding to BIE separately from the Bureau of Indian Affairs (BIA), and DOI considers BIE as an independent bureau from BIA. Also, effective October 1, 2020, many of the trust responsibilities previously performed by the Office of the Special Trustee for American Indians were transferred to a newly established Bureau of Trust Funds Administration (BTFA), according to DOI. This change is reflected with a dashed arrow. However, Congress indicated that it “does not accept the Department’s decision to move forward” with the creation of the BTFA.16 The special trustee and the principal deputy special trustee continue to report directly to the Secretary. For more information on the status of this reorganization, see “Recent DOI Reorganization Plans, Proposals, and Issues for Congress.” Leadership The leadership team and senior executives of DOI provide oversight DOI Presidential Appointees Requiring and guidance for the department's ’s Senate Confirmation various offices, bureaus, and field Secretary locations. The department is Deputy Secretary administered and overseen by the Assistant Secretary—Fish, Wildlife, and Parks Secretary of the Interior (referred to in Assistant Secretary—Insular Affairs this report as the Secretary) and a Deputy Secretary, who serves in a leadership capacity under the Secretary. The President appoints both positions, and the U.S. Senate confirms them (see Assistant Secretary—Land and Minerals Management Deputy Secretary, who serves in a Assistant Secretary—Policy, Management, and Budget leadership capacity under the Assistant Secretary—Water and Science Secretary. The President appoints both Assistant Secretary—Indian Affairs positions, and the U.S. Senate confirms Chairman, National Indian Gaming Commission them. (See text box for a full list of text box for a full list of DOI appointees requiring Senate confirmation). Serving under the Secretary and Deputy Secretary are six Assistant Secretaries, who oversee DOI's nine technical bureaus and different Special Trustee for American Indians confirmation.) Serving under the Commissioner, Bureau of Reclamation Secretary and Deputy Secretary are six Director, Bureau of Land Management Assistant Secretaries, who oversee Director, U.S. Fish and Wildlife Service DOI’s bureaus and administrative and Director, National Park Service administrative and programmatic offices.

Final y, the chairperson of the National Indian Gaming Commission oversees an independent regulatory body within DOI responsible for administering and promoting economic development through gaming on Indian lands.20 Similar to the special trustee, the chairperson of the commission operates in an independent capacity separate from the Assistant Secretary— Indian Affairs (AS-IA). Recent DOI Reorganization Plans, Proposals, and Issues for Congress Congress uses a variety of tools—including authorizing legislation, appropriations legislation, and oversight activities—to shape and organize the executive branch and its agencies.21 Often, changes are made through internal office transfers and/or budget realignments approved by Congress through the appropriations process. In other cases, Congress has considered more extensive executive branch reorganization efforts that have broader operational implications for an agency or for the department as a whole (see “Department-Wide Reorganization Plan”). In recent years, Congress has considered, made, or approved several changes to DOI and its organizational structure. In addition, some changes to DOI and its agencies have been proposed for FY2021 but may not yet be in effect or are stil under consideration. The 115th Congress approved several internal office transfers and realignments, including the transfer of appropriations for the Office of Natural Resources Revenue (ONRR) from DOI’s Office of the Secretary to Department-Wide Programs.22 In addition, the 116th Congress approved the consolidation of ethics staffing and funds from across DOI to the Departmental Ethics Office in the Office of the Solicitor, essential y implementing proposals put forth by DOI in the FY2021 budget justification and by the Secretary as part of Secretarial Order (S.O.) 3375.23 In 2016, Congress enacted legislation related to the reorganization of the Office of the Special Trustee for American Indians (OST).24 The Indian Trust Asset Reform Act (ITARA) directed the Secretary of the Interior to—among other things—“ensure that appraisals and valuations of Indian trust property are administered by a single bureau, agency, or other administrative entity within the Department” not later than 18 months after enactment.25 Congress subsequently approved a transfer of the Office of Appraisal Services within OST to the Office of the 18 Inspector General Act of 1978 (P.L. 95-452, 92 Stat. 1101). 19 60 Stat. 312, 43 U.S.C. §1455. 20 Indian Gaming Regulatory Act, P.L. 100-497, 102 Stat. 2469, 25 U.S.C. §2704. 21 For a more complete discussion of Congress’s constitutional responsibility in establishing the structural organization of the executive branch, see CRS Report R44909, Executive Branch Reorganization, by Henry B.

On the effective date, al functions and personnel previously under OST were transferred to BTFA, according to DOI. Per S.O. 3384, the BTFA is led by a director, who reports directly to the AS-IA, whereas the positions of the special trustee and the principal deputy special trustee continue to report separately to the Secretary.29 According to DOI, although the positions of special trustee and principal deputy special trustee stil exist, they are no longer fil ed as of the publication of this report.30 In the explanatory language for the FY2021 Interior Appropriations Act, Congress stated that it “does not accept the Department’s decision to move forward with its budget proposal to create [the] BTFA without waiting for the resolution of the proposal through the fiscal year 2021 appropriations process and over the clear objections of the House of Representatives.”31 Congress further expressed that it “expected that the incoming Administration wil perform its own analysis of its trust responsibilities under the 1994 Act and subsequent legislation and that committees of jurisdiction, including the House and Senate Appropriations Committees, wil consider any proposals to address the future disposition of OST without prejudice.”32 (For more information, see “Bureau of Trust Funds Administration (Office of the Special Trustee for American Indians).”33 Department-Wide Reorganization Plan The Trump Administration also proposed broader DOI reorganization activities.

T he text also states, “ The decision to transfer the functions of OST wholesale into a new bureau also raises questions about whether it is consistent with provisions of the 1994 Indian T rust Reform Management Act (P.L. 103-412), which created OST on a temporary basis until the completion of certain trust reforms, or with the existing transition plan for OST proposed by the Administration and adopted by Congress in fiscal year 2019.” 32 Ibid. 33 According to DOI, the Secretary has the legal authority under the Reorganization Plan No. 3 of 1950 to create the BT FA. DOI considers the establishment of the BT FA finalized as of October 1, 2020.

Included in this proposal was a plan to consolidate the different regional boundaries of each DOI bureau into 12 Unified Interior Regional Boundaries. In August 2018, DOI official y announced the designation of its 12 new Unified Interior Regional Boundaries (see Figure 3).35 According to DOI, the BIA, BIE, and OST were excluded from this realignment and retained their existing regional boundaries.36 In addition to the consolidation of regional boundaries, the plan sought to shift some resources “to the field,” potential y in the form of staff, budget, and/or facilities.37 In FY2019, Congress appropriated funds for the reorganization of BLM, FWS, NPS, USGS, and Reclamation.38 The Administration’s request indicated that this funding was intended to support the establishment of the new Unified Interior Regional Boundaries and to “shift some BLM, FWS, and Reclamation headquarters staff to the West.”39 As part of the broader DOI reorganization effort, the Trump Administration announced plans to relocate most BLM positions and personnel based in Washington, DC, to BLM state offices across the West and to establish a new BLM headquarters office in Grand Junction, CO. The Administration cited potential benefits of the move, including cost savings from lower office lease payments and travel costs, as wel as enhanced integration of policy and operations personnel, understanding of western needs, decisionmaking in the field, and partnerships with communities and organizations. The relocation was controversial, with some stakeholders raising concerns around the costs of relocation, a loss of expertise due to senior staff who did not relocate, a possible decline in staff diversity, and potential difficulty for BLM leadership to coordinate with DOI management. On August 10, 2020, the Secretary of the Interior signed S.O. 3382, which formal y established the new Grand Junction headquarters office.40 34 Executive Order 13781, “Comprehensive Plan for Reorganizing the Executive Branch,” 82 Federal Register 13959-13960, March 13, 2017. 35 DOI, “ Establishment of Unified Regional Boundaries for the Department of the Interior ,” August 29, 2018, at https://www.doi.gov/employees/reorg/establishment -unified-regional-boundaries-department -interior (accessed in March 2021). 36 DOI, “Interior Reorganization,” at https://www.doi.gov/employees/reorg (accessed in March 2021). 37 Ibid. 38 Congress appropriated $14.1 million for the reorganization of the Bureau of Land Management ( BLM), U.S. Fish and Wildlife Service (FWS), National Park Service (NPS), and U.S. Geological Survey (USGS) through Interior, Environment, and Related Agencies Appropriations laws (see H.Rept. 116-9). T he accompanying report does not identify the portion of the appropriation for each of the five agencies. T he FY2019 request also sought $3.4 million for the reorganization of Reclamation.

65 Bureau of Reclamation (Reclamation)

The large-scale construction of federal dams and irrigation projects throughout the 20^th century was born, in part, out of a growing need for water supplies in the arid and rapidly expanding western United States.⁴⁷ To meet this need, Congress passed the Reclamation Act of 1902, which set aside federal dollars to fund irrigation projects and large-scale dam construction in the arid and rapidly expanding western United States.66 projects in 13 western states.⁴⁸

Shortly thereafter, Congress established the U.S. Reclamation Service as a program within the U.S. Geological Survey (USGS). In its first five years, the service began work on more than 30 projects across the American West. In 1907, the Secretary of the Interior elevated the program to an independent bureau within DOI before renaming it the Bureau of Reclamation (Reclamation) in 1923.⁴⁹67 Since its establishment, Reclamation has constructed or overseen the completionconstruction of more than 600 projectsdams and reservoirs across the western United States.⁵⁰ 68 Beneficiaries of thesereclamation projects generallygeneral y repay the costs for construction and operations of 65 BOEM, Budget Justifications and Performance Information Fiscal Year 2021, p. 83, at https://www.boem.gov/sites/default/files/documents/about-boem/budget/FY%202021%20Budget%20Justification.pdf.

The U.S. Fish and Wildlife Service (FWS) is the principal federal agency tasked with the conservation, protection, and restoration of fish, wildlife, and natural habitats across the United States and its insular territories. The history of FWS can be traced back to the creation of two now-defunct agencies in the late 1800s: the U.S. Commission on Fish and Fisheries in the Department of Commerce and the Division of Economic Ornithology and Mammalogy in the Department of Agriculture.⁷² These89 The successors to these two agencies were subsequently transferred to DOI in 1939 and subsequently consolidated, creating a single agency known at the time as the Fish and Wildlife Service.⁷³ In 1956, Congress established the U.S. Fish and Wildlife Service.⁷⁴

Eliot Crafton. Congressional Research Service 19 U.S. Department of the Interior: An Overview Fish and Wildlife Service.90 In 1956, Congress passed the Fish and Wildlife Act of 1956, which established the U.S. Fish and Wildlife Service.91 The FWS has a primary-use mission “to conserve, protect and enhance fish, wildlife and plants to conserve, protect and enhance fish, wildlife and plants and their habitats for the continuing benefit of the American people."⁷⁵”92 Among its responsibilities, FWS manages the National Wildlife Refuge System (NWRS) under the authority granted bypursuant to the National Wildlife Refuge System Administration Act of 1966.⁷⁶ as wel as other statutes.93 The NWRS is a network of lands and waters set aside to conserve the nation'’s fish, wildlife, and plants that has grown to include more than 560 refuges, 38 wetland management districts, and other protected areas. More than 836 million mil ion acres of lands and waters comprise the NWRS; of these lands and waters, 146 million mil ion acres are classified as National Wildlife Refuges.⁷⁷

94 In addition, FWS, along with the National Oceanic and Atmospheric Administration (NOAA) in the Department of Commerce, is responsible for implementing the Endangered Species Act (ESA).⁷⁸ The ESA aims95 The purpose of the ESA is to protect species that are in danger of becoming extinct or could be in danger of becoming extinct in the near future.⁷⁹96 FWS also assists in international conservation efforts, enforces federal wildlife laws, and administers grant funds to states and territories for fish and wildlife programs.

Similar to most DOI agencies, FWS has a three-tiered organizational structure comprisedcomposed of national, regional, and local field offices across the United States. The headquarters office—led by an agency director—is split between two locations in Washington, DC, and FallsFal s Church, VA, which together have primary responsibility for policy formulation and budgeting across the agency's 13 majoragency’s program areas.⁸⁰97 Eight regional offices oversee FWS field offices and science centers across the United States and U.S. territories, which implement these policies and programs at the local level.98 90 Reorganization Plan Number III of 1940, 5 U.S.C Appendix —Reorganization Plans. 91 Fish and Wildlife Act of 1956, 70 Stat. 1119, 16 U.S.C. §742a. 92 FWS, “About the U.S. Fish and Wildlife Service,” at https://www.fws.gov/help/about_us.html. 93 National Wildlife Refuge System Administration Act of 1966, P.L. 89-669, 16 U.S.C. §§668dd et seq.

U.S. Geological Survey (USGS)

. In 1878, the National Academy of Sciences issued a report to Congress asking Congress to provide a plan for surveying and mapping the western territories of the United States.⁸³99 In response, Congress passed an appropriations bill bil the following year that authorized the creation of the U.S. Geological Survey (USGS). Congress established the USGS for the express purpose of overseeing the "“classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain."⁸⁴”100 The authorities and responsibilities of USGS have shifted and evolved over time, with many of its prior activities leading to the formation of new governmental agencies.⁸⁵101 Today, however, USGS serves as the science agency of DOI, providing physical and biological information across seven interdisciplinaryfive mission areas: (1) water resources, (2) climate and land use change, (3) energy and minerals, (4) energy and mineral resources, (3) natural hazards, (54) core science systems, (6) ecosystems, and (7) environmental health.⁸⁶, and (5) ecosystems.102 Unlike other DOI bureaus, USGS has no regulatory or land management mandate.

In addition to its seven programmatic areas, USGS is further organized into seven geographic regions, each under the supervision of a regional director. The regional directors report to a presidentially appointed director based out of the agency's headquarters in Reston, VA. Within each region A presidential y appointed director based out of the agency’s headquarters in Reston, VA, administers USGS and oversees seven regional directors across the country. In addition to regional offices, USGS operates science centers, laboratories, and field offices that monitor, assess, and conduct research on a wide range of topics.⁸⁷ Overall, USGS had roughly 8,000 employees as of June 2018.⁸⁸

Departmental Offices and Programs⁸⁹

In addition to the nine technical bureaus, DOI has multiple departmental offices that provide leadership, coordination, and services to the department'103 99 Rabbitt, United States Geological Survey. 100 Sundry Civil Expenses bill, passed on March 3, 1879, 43 U.S.C. §31. 101 Rabbitt, United States Geological Survey.

level. Office of the Secretary

The Office of the Secretary provides leadership for the entire department through the development of policy and through executive oversight of the annual budget and appropriations process. The Office of the Secretary also manages the administrative operations of DOI, including (but not limited to) financial services, information technology and resources, acquisition, and human resources. In addition, the Office of the Secretary manages six other department-wide programs, offices, and revolving funds:

• 1. , including the following:  Central Hazardous Materials Fund provides remediation services to national parks, national wildlife refuges, and other DOI-managed lands impacted by hazardous substances. This remediation process follows the guidelines established under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)—also known as the Superfund statute.⁹⁰
• 2. 105  Natural Resource Damage Assessment and Restoration program coordinates and oversees DOI'’s restoration efforts for DOI-managed lands impacted by oil spills spil s or the release of hazardous substances. In partnership with federal, state, and tribal co-trustees, the program conducts damage assessments, planning, and restoration implementation on DOI lands.
• 3.  Office of Natural ResourcesResources Revenue (ONRR) is responsible for the collection, accounting, and verification of any natural resource and energy revenue generated from federal and Indian leases and royalty payments. (See "“Bureau of Ocean Energy Management" ” section for the history behind ONRR'’s creation.)
• 4.  Payments in Lieu of Taxes (PILT) program makes payments to nearly approximately 1,900 local government units across the United States and its insular areas where certain federal lands are located. The PILT payments are intended to help offset the loss in property taxes to local governments caused by the presence of federal lands, which largely are exempt from taxation.⁹¹
• 5. 106  Wildland Fire Management program is responsible for addressing wildfires on public lands. The program is comprisedcomprises of the Office of Wildland Fire and the four 104 T his section does not represent all DOI divisions and programs. Instead, it reflects the offices and programs included as discrete line items under the Departmental Offices and Department -Wide Programs accounts funded through the annual Interior, Environment, and Related Agencies appropriations bill (see “ Overview of DOI Appropriations” section for more information). OST is discussed here; however, FY2021 appropriations were requested and provided as part of the Indian Affairs account. Prior to FY2021, appropriations for (OST typically were provided as part of the Departmental Offices account. 105 Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, P.L. 96-510, approved December 11, 1980. 42 U.S.C. §§9601 et seq.

• 6. 107  Working Capital Fund (WCF) is a revolving fund that finances centralized administrative services and systems to DOI bureaus and offices.⁹³108 The WCF aims to reduce duplicative systems and staff across DOI; it provides financing for centralized functions that provide payroll, accounting, information technology, and other support services.

Office of the Solicitor

In 1946, Congress established the Office of the Solicitor to provide advice, counsel, and legal representation to DOI.⁹⁴ The office manages DOI's Ethics Office and resolves Freedom of Information Act appeals.109 To accomplish this work, the Office of the Solicitor employs more than 400500 employees, 300400 of whom are licensed attorneys.⁹⁵110 The Office of the Solicitor is organized into the Immediate Office of the Solicitor, the Departmental Ethics Office, fivethe Departmental FOIA (Freedom of Information Act) Office, the Indian Trust Litigation Office, six legal divisions, legal divisions, an administrative division, and eight regional offices.⁹⁶

111 Office of the Inspector General

In 1978, Congress established inspector general positions and offices in more than a dozen specific departments and agencies, including DOI.⁹⁷112 The mission of the Office of the Inspector General (OIG) is to provide independent oversight and accountability to the department’s programs, operations, and management. In addition to the Immediate Office of the Inspector General, the OIG has five offices: the Office of Management; the Office of Investigations; the Office of Audits, Inspections, and Evaluations; the Office of General Counsel; and the Office of Strategic Programs.113 The OIG operates from a headquarters office in Washington, DC, and regional offices located in Herndon, VA; Atlanta, GA; Lakewood, CO; Bil ings, MT; and programs, operations, and management of the department. OIG has three primary office divisions: (1) the Office of Management serves as the administrative arm; (2) the Office of Investigations conducts, supervises, and coordinates internal investigations on a variety of potential abuses; and (3) the Office of Audits, Inspections, and Evaluations reviews DOI programs and operations for effectiveness and evaluates the financial statements and expenditures of these programs.⁹⁸ The OIG also operates three regional offices, located in Herndon, VA; Lakewood, CA; and Sacramento, CA.

Sacramento, CA.114 Bureau of Trust Funds Administration (Office of the Special Trustee for American Indians) The status and operation of the Office of American Indians

The American Indian Trust Fund Management Reform Act established the Office of the Special Trustee for American Indians (OST) in 1994.⁹⁹ The OST provides fiduciary oversight and management of the more than 55 million surface acres and 57 million subsurface mineral acres of tribal assets held in trust by the federal government.¹⁰⁰ The office carries out its mission from a national office in Washington, DC, and through five regional offices across the nation.¹⁰¹

Special Trustee for American Indians (OST has been an issue of congressional interest in recent years. According to DOI, the Bureau of Trust Funds Administration (BTFA) currently performs the functions of the OST.115 The American Indian 107 Reclamation also has limited responsibility to manage land under its jurisdiction for wildfires.

DOI considers the BTFA operational; however, Congress has expressed concerns regarding the creation of the BTFA (see “Recent DOI Reorganization Plans, Proposals, and Issues for Congress” for more information). For the purposes of this report, CRS has treated the establishment of the BTFA as operational. Office of Insular Affairs Office of Insular Affairs

The United States acquired its first insular territories in 1898 with the annexation of the Hawaiian Hawai an Islands and the acquisition of Puerto Rico, Guam, and the Philippines from Spain following the Spanish-American War.¹⁰⁵ 119 For much of the early 20th century, territorial oversight of these new possessions fell fel largely to the War Department. In 1934, President Franklin D. Roosevelt created the Division of Territories and Island Possessions to centralize responsibility for coordinating oversight of the nation'’s insular regions.¹⁰⁶120 The division—now known as the Office of Insular Affairs—currently administers federal oversight of American Samoa, Guam, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands, with the goal of promoting their economic, social, and political development.¹⁰⁷121 The office also administers federal assistance and U.S. economic commitments to the Freely Associated States: the Federated States of Micronesia, the Republic of the Marshall Marshal Islands, and the Republic of Palau.¹⁰⁸

122 DOI Employment Levels

As of June 2018, the total In 2020, the average number of employees working for DOI was 69,56363,175, according to OPM. (See (see Table 1).¹⁰⁹.)123 The data reflect "on-board employment" figures, which calculateare based on the number of employees in pay status at the end of the quarter. Data are published on a quarterly basis (March, June, September, and December); however, figures for September and December 2018 were not available prior to the publication of this report. Data in this report reflect December 2020 figures, unless 116 P.L. 103-412, 108 Stat 4239. 117 Bureau of T rust Funds Administration (BT FA), “About Us,” at https://www.doi.gov/ost/about_us (accessed on February 4, 2021).

For a more complete discussion of FAS policies, see CRS Report R44753, The Pacific Islands: Policy Issues, by T homas Lum and Bruce Vaughn. 123 OPM is an independent agency that functions as the central human resources department of the executive branch and is a primary source for data and information regarding DOI employment figures—as well as the entire federal workforce. For a more complete discussion of OPM data, see CRS Report R43590, Federal Workforce Statistics Sources: OPM and OMB, by Julie Jennings and Jared C. Nagel. Congressional Research Service 24 link to page 29 link to page 30 U.S. Department of the Interior: An Overview otherwise specified. Because OPM data include full-time, part-time, and seasonal staff, employment totals tend to spike during the summer months, when agencies such as NPS, BLM, and FWS and BLM increase their seasonal workforce.

OPM figures differ from DOI Budget Office data. The DOI Budget Office calculates employment by full-time equivalents (FTEs), defined as the total number of regular straight-time hours (not including overtime or holiday hours) worked by employees, divided by the number of compensable hours applicable to each fiscal year.¹¹⁰

The OPM Fedscope data presented in in Table 1 are available by location of employment for each bureau and office reflected. Table 2 shows DOI employment figures both within and outside the DC core-based statistical area (CBSA). OPM defines a CBSA as "a geographic area having at least one urban area of population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties."¹¹¹ CBSAs differ from metropolitan statistical areas (MSAs)—a separate statistical definition also reported on by OPM—which typically encompass a smaller geographic area than CBSAs. For example, the DC MSA includes many but not all of the counties and surrounding cities covered under the DC CBSA. For instance, the DC MSA excludes Reston, VA, where the headquarters of USGS is located.¹¹²

Overview of DOI Appropriations

Discretionary funding for DOI is provided primarily through Title I of the annual Interior, Environment, and Related Agencies appropriations bill.¹¹³ The Bureau of Reclamation (Reclamation) and the Central Utah Project are the exceptions, as they receive funding through the Energy and Water Development appropriations bill.¹¹⁴ Several of the agencies that receive discretionary funds through these two appropriations bills also receive mandatory funding under various authorizing statutes.

DOI Discretionary Appropriations: FY2014-FY2018¹¹⁵

Figure 3 shows the budget trends for both the Interior and the Energy and Water appropriations bills over the past five fiscal years (FY2014-FY2018). From FY2014 to FY2018, total DOI appropriations increased 29% in current dollars. This increase includes the $566 million in FY2018 emergency supplemental appropriations for disaster relief appropriated to DOI in P.L. 115-72 and P.L. 115-123. If supplemental appropriations are not considered, total DOI appropriations increased 23% over the same period.¹¹⁶

DOI Reorganization Plans and Proposals: Issues for Congress

The 114^th Congress passed legislation authorizing the reorganization of the Office of the Special Trustee for American Indians (OST). In 2016, ITARA directed the Secretary to—among other things—"ensure that appraisals and valuations of Indian trust property are administered by a single bureau, agency, or other administrative entity within the Department" not later than 18 months after enactment.¹²⁰ To comply with this requirement, the FY2019 budget request reflects the approved transfer of the Office of Appraisal Services within OST to the Office of the Secretary's Appraisal and Valuation Services Office, thereby consolidating all appraisal activities within a single entity.¹²¹ This change is in addition to a proposed shift in the reporting relationship of OST also included in the FY2019 request. Under this proposal, starting in FY2019, OST would report through the Office of the Assistant Secretary of Indian Affairs rather than directly to the Office of the Secretary (see Figure 2).¹²²

As noted in the "Introduction" to this report, the Trump Administration also proposed additional, broader DOI reorganizational plans for consideration. On March 13, 2017, President Trump issued Executive Order 13781 to "improve the efficiency, effectiveness, and accountability of the executive branch."¹²³ The order required executive agency heads to, "if appropriate," submit a proposed reorganization plan for their agencies to the director of the Office of Management and Budget within 180 days. Then-Secretary of the Interior Zinke subsequently submitted a proposal for reorganization aimed at—among other goals—improving agency coordination and service to the public.¹²⁴ Included in this proposal is a plan to consolidate the various agency-specific regional boundaries (as seen in the "At a Glance" boxes included in each bureau summary) into 12 Unified Regional Boundaries. In addition, the plan looks to shift some resources and authority "to the field," potentially in the form of staff, budget, and/or facilities.
