What is the FARR?

The Federal Air Rules for Indian Reservations are a set of air quality regulations that apply to Indian reservations in Idaho, Oregon and Washington. The FARR became effective on June 7, 2005.

Proposed Revisions to the FARR

EPA is proposing changes to the FARR. These proposed revisions are expected to improve air quality protections for people living on reservations and are focused on reducing particulate matter emissions in areas with elevated levels, improving program implementation, and addressing emerging air quality concerns on reservations. Learn more about the proposed changes.

Who's covered by the FARR?

The FARR applies to all residents (both tribal members and non-tribal members) and businesses located within the federally-recognized exterior boundaries of the 39 reservations in Idaho, Oregon and Washington listed in the table below.

The ownership status of land on the reservation does not affect how the FARR rules apply.

Why is the FARR important?

The FARR protects human health and the environment for approximately 200,000 people on reservations in the Pacific Northwest. Before these rules were passed, very few basic air quality rules applied to Indian reservations under the federal Clean Air Act. State and local air agencies do not have authority to administer their rules on Indian lands.

The EPA has not yet approved any tribal-managed air programs in Idaho, Oregon and Washington, so the FARR is an important step in ensuring that federally enforceable rules are in place to provide basic air quality protection on these reservations.

Who enforces the FARR?

The EPA has sole enforcement authority under the FARR.
