The annual Interior, Environment, and Related Agencies appropriations bill includes funding for agencies and programs in three separate federal departments as well as numerous related agencies. The bill typically contains three primary titles. Title I provides funding for most Department of the Interior (DOI) agencies, many of which manage land and other natural resource or regulatory programs. Title II contains appropriations for the Environmental Protection Agency (EPA). Title III funds agencies in other departments, such as the Forest Service in the Department of Agriculture and the Indian Health Service in the Department of Health and Human Services; arts and cultural agencies, such as the Smithsonian Institution; and various other entities. Title III of the bill is referred to as "Related Agencies." Neither the House nor the Senate passed regular FY2015 appropriations for Interior, Environment, and Related Agencies before the start of the fiscal year on October 1, 2015. Before that date, the House Appropriations Committee had reported H.R. 5171 , the Department of the Interior, Environment, and Related Agencies Appropriations Act, 2015, containing FY2015 appropriations, and the chairman of the Senate Appropriations Subcommittee on Interior, Environment, and Related Agencies had released a draft measure and accompanying explanatory statement. Neither measure had subsequent legislative action. Because regular FY2015 appropriations were not enacted prior to October 1, 2015, continuing appropriations were temporarily provided after that date. Under the Continuing Appropriations Resolution, 2015 (CR), agencies generally received funding at the FY2014 level minus an across-the-board reduction of 0.0554%. Funding was generally provided under the authority and conditions, and to the same extent and manner, as in FY2014. Further, funding could not be used to initiate or resume projects or activities for which funding or authority was not provided for FY2014. The CR provided appropriations through December 11, 2014; two subsequent laws extended continuing funding through December 17, 2014. On December 16, 2014, regular FY2015 appropriations were enacted for Interior, Environment, and Related Agencies as part of P.L. 113-235 . The law included total appropriations of $30.48 billion for these agencies, primarily in Division F. This report provides a brief overview of FY2015 appropriations levels. It first addresses the appropriations requested by the President for FY2015 for agencies in the bill and compares the requested appropriations with FY2014 enacted appropriations. It next discusses the FY2015 appropriations contained in H.R. 5171 as reported by the House Appropriations Committee and the appropriations recommended in the Senate Interior Subcommittee draft. It then summarizes the components of the FY2015 enacted appropriations and compares the FY2015 enacted level with funding enacted for the prior five years (FY2010-FY2014) and recommended for FY2015. Appropriations are complex. For example, the budget requests for some agencies are large, numbering several hundred pages and containing numerous funding, programmatic, and legislative changes for congressional consideration. Further, appropriations laws provide funds for numerous accounts, activities, and subactivities, and the accompanying explanatory statements provide additional directives and other important information. This report does not provide account- and subaccount-level information. Further, it does not discuss agency highlights under the President's request, the House committee-reported bill, the Senate Interior Subcommittee draft, or the FY2015 appropriations law, such as increases, decreases, budgetary reorganizations, and legislative changes. For information on FY2015 appropriations for a particular agency, or for individual accounts, programs, or activities administered by a particular agency, contact the key policy staff identified at the end of this report. For FY2015, the President requested $30.69 billion for the approximately 30 agencies and entities typically funded in the annual Interior, Environment, and Related Agencies appropriations law. For the 10 major DOI agencies in Title I of the bill, the request was $10.86 billion, or 35.4% of the total requested. For EPA, funded by Title II of the bill, the request was $7.89 billion, or 25.7% of the total. For about 20 agencies and other entities typically funded in Title III of the bill, the request was $11.94 billion, or 38.9% of the total. Appropriations for agencies vary widely for a number of reasons relating to the number, breadth, and complexity of agency responsibilities; alternative sources of funding (e.g., mandatory appropriations); and Administration and congressional priorities, among other factors. Thus, although the President's FY2015 request covered approximately 30 agencies, funding for a small subset of these agencies accounted for most of the total. For example, the appropriations for three agencies—EPA, Forest Service, and Indian Health Service—were about three-fifths (59.4%) of the total requested. Further, more than three-quarters (76.3%) of the request was for these three agencies and two others—National Park Service and Bureau of Indian Affairs. For DOI agencies, the requests ranged from $72.4 million for the Bureau of Ocean Energy Management to $2.61 billion for the National Park Service. The requests for 6 of the 10 agencies exceeded $1 billion. Nearly half (47.7%) of the $10.86 billion requested for DOI agencies was for two agencies—the National Park Service and Bureau of Indian Affairs. For Related Agencies in Title III, the requested funding levels showed even more variation. The President did not seek funding for one agency that received FY2014 appropriations (National Capital Arts and Cultural Affairs), and the President sought amounts ranging from $2.5 million for the Commission of Fine Arts to $5.71 billion for the Forest Service. Other than the Forest Service, the Indian Health Service would have been the only other agency to receive more than $4 billion under the President's proposal. The next-largest request was for the Smithsonian Institution, at $850.9 million. By contrast, 14 agencies would have received less than $80 million each, including 7 with appropriations of less than $10 million each. Figure 1 identifies the share of the President's request for each of the three titles of the Interior bill. It also depicts the portion of funding requested for particular agencies. Table 1 contains the amount requested by the President for FY2015 for each agency in the Interior bill, the FY2014 enacted appropriations, and the percentage change from FY2014 as compared with the President's request for FY2015. The President's request of $30.69 billion for FY2015 would have been an increase of $570.9 million (1.9%) over the total FY2014 enacted appropriations of $30.12 billion. For FY2014, most of the $30.12 billion was provided in the Consolidated Appropriations Act, 2014. However, $628.5 million of the total was included in the Continuing Appropriations Act, 2014. The overall increase proposed for FY2015 was the result of various increases and decreases sought for different agencies/entities. For instance, under the President's proposal, the total for all DOI agencies would have increased by $381.3 million (3.6%), funding for EPA would have decreased by $310.0 million (-3.8%), and the total for all Related Agencies in Title III would have increased by $500.5 million (4.4%). With regard to DOI, for 7 of the 10 agencies the President proposed increases above FY2014. The increases varied in dollar amount and percentage of appropriations, with the lowest dollar increase of $2.4 million (3.1%) for the Bureau of Safety and Environmental Enforcement and the highest of $182.2 million (19.5%) for Department-Wide Programs. Most of the increase under Department-Wide Programs was for Wildland Fire Management. For the other three DOI agencies, the President sought decreases varying from $5.3 million (-3.5%) for the Office of Surface Mining Reclamation and Enforcement to $10.4 million (-1.7%) for Departmental Offices. The President's proposed overall decrease for EPA was largely due to a $529.8 million reduction (-15.0%) for the State and Tribal Assistance Grants (STAG) account. Most of the proposed decrease in the STAG account was attributed to a combined reduction below the FY2014 enacted funding for grants that provide financial assistance to states to help capitalize Clean Water and Drinking Water State Revolving Funds (SRFs). Respectively, these funds finance local wastewater and drinking water infrastructure projects. The STAG account also includes funds for other grants used by states and tribes. The President sought overall increases for all other EPA accounts above the FY2014 enacted levels. The $113.0 million (4.3%) increase for the Environmental Programs and Management (EPM) account was the largest overall dollar increase among the EPA accounts. The EPM account funds a broad array of activities supporting EPA's development and enforcement of pollution control regulations and standards, technical assistance, and administrative and operational expenses. The President's overall increase proposed for Title III agencies reflected various increases and decreases. Half of the agencies would have received higher funding under the request, but the three largest agencies would have received the largest dollar increases. Specifically, the President sought an additional $227.6 million (4.2%) for the Forest Service, $199.7 million (4.5%) for the Indian Health Service, and $45.9 million (5.7%) for the Smithsonian Institution. The increase for the Forest Service would have been primarily for suppressing wildland fires and for the National Forest System account. The Indian Health Service would have received additional funds for many programs and activities, including clinical services and contract support costs.
