EPA’s historic EPA-Tribal accomplishments timeline highlights key milestones over the last 50 years

Portrait Photograph of Chad McIntosh“This year marks the Environmental Protection Agency’s 50th anniversary. EPA has developed an historic EPA-Tribal accomplishments timeline, highlighting some of the key milestones that have shaped EPA’s successful partnership with tribes and led to environmental progress over the last 50 years.  For example, EPA has completed a record number of tribal requests authorizing Indian tribes to implement specific environmental programs, similar to a state.  I am particularly proud of the productive and successful relationship EPA has with federally-recognized tribes – based on mutual respect and trust. We have made meaningful progress building capacity and protecting human health and the environment in Indian country.” 

-- Chad McIntosh Assistant Administrator for International and Tribal Affairs


Portrait Photograph of Scott Mason“For the past 50 years, EPA has relied on the hard work of our tribal partners and our dedicated expert staff to address environmental challenges and in strengthening environmental and public health protection in Indian country. EPA looks forward to collaborating with tribal partners to build capacity in environmental and health protections over the next 50 years.”

-- Scott Mason, EPA Director of the American Indian Environmental Office



President Richard Nixon Issues a Special Message to Congress on Indian Affairs Expressing the Federal Government’s Commitment to a New Self-Determination Era for Tribes

President Nixon signs a commitment to Indian self-determination.This action establishes federal policy for “a new and balanced relationship between the United States government and the first Americans, that is at the heart of our approach to Indian problems” – a tribal future determined by tribal government acts and decisions. With this action, the President sets the stage for the newly created EPA to begin incorporating self-determination principles into its tribal program from the Agency’s very beginning. Although the language from 50 years ago is somewhat dated, the President recognized the need for partnership declaring that: “The Indians of America need Federal assistance … [and]… the Federal Government needs Indian energies and Indian leadership.” The following EPA 50th Anniversary Tribal Program Milestones show EPA’s steady progress towards meeting the self-governance goal of tribal implementation of federal environmental program on their lands.

EPA Becomes the First Federal Agency With an Official Indian Policy

A picture of the memorandum 'EPA Policy for Program Implementation on Indian Lands'.Titled EPA Policy for Program Implementation on Indian Lands, the Policy expresses EPA’s commitment to working with tribes and EPA’s belief that tribes play a key role in implementing pollution control programs affecting their reservations. The Policy sets the stage for future EPA tribal program developments and successes.



EPA Issues Its Current Indian Policy

Administrator Bill Ruckelshaus is the first Administrator to affirm EPA’s Indian Policy in 1984Under President Reagan and Administrator Ruckelshaus EPA’s Policy for the Administration of Environmental Programs on Indian Reservations, commonly referred to as “EPA’s 1984 Indian Policy” was issued. The Policy has been consistently reaffirmed by EPA Administrators since 1984, most recently by Administrator Andrew Wheeler in 2019. EPA commits to considering tribal interests in carrying out its programs. Consistent with the overall Federal position in support of tribal self-government and government-to-government relations, the Policy principles include recognizing tribes as the appropriate entities to set standards, make environmental policy decisions, and manage programs for reservations. The Policy remains the cornerstone for EPA’s tribal program to this day.

EPA’s current Administrator Andrew Wheeler reaffirms EPA’s 1984 Indian Policy in 2019.Read more about EPA’s 1984 Indian Policy.



Congress Begins Amending Major Environmental Statutes to Create New Roles for Tribes in Administering Regulatory Programs

Wild Rice near Mille Lacs Band of OjibweBeginning with the Safe Drinking Water Act in 1986, Congress allows EPA to approve eligible tribes to implement the Public Water System Supervision and the Underground Injection Control programs and enforce approved tribal regulations under these programs. The SDWA became the first statute giving tribes the opportunity to pursue regulatory primacy through an approval process known as “treatment as a state” or TAS. That same year, the Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, also called “Superfund,” was amended to give tribes substantially the same role as states for aspects of the Superfund process, including responding to releases of hazardous substances and pollutants or contaminants. Then in 1987 and 1990, respectively, the Clean Water Act and Clean Air Act amendments authorize EPA to approve eligible tribes to administer a wide array of programs under those statutes, including: 1) establishing tribal standards for water quality for submission to EPA and implementing such standards through approved CWA programs, and 2) implementing virtually all of the significant clean air programs.

EPA Creates a Forum to Formally Engage With States and Tribes on Environmental Topics

FOSTTA focused on pollution prevention, and other activities in coordination with EPA’s Office of Chemical Safety and Pollution Prevention.EPA creates the Forum on State and Tribal Toxics Action Pollution Prevention Project (FOSTTA) to improve communications with states and tribes. FOSTTA secured senior state and tribal officials interested in and with knowledge of pollution prevention issues and programs to help guide pollution prevention activities in EPA. Projects revolve around lead, toxics release inventory, chemical management and pollution prevention issues, and feature two workgroups on tribal and community based environmental protection.



The Indian Environmental General Assistance Program Act (GAP) Creates a New EPA Tribal Grant Program to Help Tribes Build Environmental Program Capacity.

EPA featured the Confederated Salish and Kootenai Tribes in a recent GAP Success Story.Tribes use GAP grants for planning, developing and establishing environmental protection programs, and implementing solid and hazardous waste programs in Indian country. GAP has since become EPA’s largest tribal grant program that includes both tribes and intertribal consortia, with a recent average appropriation of over $60 million per year.

EPA Establishes a Formal Tribal Program Infrastructure in EPA.

In 2019, EPA Administrator Wheeler co-chairs the NTOC, celebrating 25 years of NTOCIn addition to creating the American Indian Environmental Office, EPA also focused on an operational structure to get advice and input from tribes by establishing the National Tribal Operations Committee (NTOC). EPA establishes the NTOC to identify, address and advise EPA on tribal environmental issues that are national in scope, cross-agency or cross-media in nature, or that may be emerging or urgent. The annual NTOC meeting is co-chaired by the EPA Administrator and the Chair of the National Tribal Caucus (NTC). The first NTOC meeting is held on February 17, 1994.

Read more about the NTOC.

Regional Tribal Operations Committees (RTOCs):
Following formation of the NTOC, EPA Regional offices began forming operational committees with tribes in their regions. In 2019, shortly after the federal recognition of seven tribes in the Commonwealth of Virginia, EPA Region 3 convenes its first Tribal Environmental Summit and for the first time all 10 EPA Regions have RTOCs.



EPA and 11 Tribes Sign Tribal Environmental Agreements (TEAs)—Furthering the EPA-Tribal Partnership.

EPA Region 5 Regional Administrator signs the first TEA.Region 5 Administrator, Valdas V. Adamkus, signed the first-ever Tribal Environmental Agreements (TEAs) between EPA and the elected leaders of eleven tribes in Minnesota. Each TEA describes EPA’s regulatory program implementation roles and responsibilities for each tribe and the tribe’s environmental priorities and baseline program needs. The TEAs used a three-year planning perspective. Today, EPA continues joint environmental planning with each tribe through EPA-Tribal Environmental Agreements. EPA has individually negotiated ETEPs with almost 500 tribes across the country.

EPA Receives Innovative New Authorities for Tribes to Develop Environmental Programs

Cover of Tribal Brownfields brochureWith the new decade come two new significant authorities. In 2001, Congress bolsters implementation of federal environmental programs in Indian country through the Direct Implementation Tribal Cooperative Agreements authority Exit. DITCA authority enables EPA to award cooperative agreements with Indian tribes and eligible intertribal consortia for tribes to act on behalf of EPA in carrying out certain implementation functions of Federal environmental programs. EPA and tribes continue to use this authority to build tribal capacity in environmental program implementation.

In 2002, tribes are eligible for Brownfields authority and funding under the Small Business Liability Relief and Brownfields Revitalization Act amendments. The new Brownfields law enables tribes to establish and enhance tribal environmental response programs, including funding for voluntary cleanup programs.

EPA Highlights 50 Years of Environmental Progress Achieved in Partnership With Tribes.

Excavating a gasoline underground storage tank on the Umatilla Indian ReservationSince the first statutory amendments for tribes to seek Treatment as a State, 67 tribes have received authority to establish water quality standards and Section 401 certification authority for their reservations, one tribe has PWSS primacy, 2 tribes have UIC primacy, and 18 tribes are implementing Clean Air Act regulatory or permit programs in Indian country (6 Tribal Implementation Plans, 2 Title V programs, and 9 tribes with delegation of the Federal Air Rules for Reservations (FARR)). An additional 6 tribes have completed Class I airshed designation. These numbers continue to grow as tribes seek a greater role in environmental protection on their own lands.

Progress is being made to address tribal water infrastructure challenges. Since 2009, EPA, in coordination with its federal partners provided access or had access restored to an estimated 84,795 American Indian and Alaskan Native homes for safe drinking water, and to an estimated 67,423 American Indian and Alaskan Native homes for basic sanitation.

Regarding cleanup of contaminated lands, since the beginning of EPA’s Underground Storage Tank (UST) Program, a total of 1,115 cleanups have been completed in Indian country. Since the 2002 Brownfields law, CERCLA 128(a) funds have been utilized to oversee the cleanup of 2,718 properties for a total of 72,545 acres on tribal lands ready for reuse. In FY19, approximately 18 tribes received funding to actively participate with EPA in the Superfund process and 94 tribes had an identified interest in a Superfund site. Read more about tribal involvement in land cleanup laws and regulations.

The EPA and its partners remain committed to working to ensure that tribal communities have access to clean and safe water, air and land.
