Federal Air Rules for Reservations Registration Program
Federal Air Rules for Reservations (FARR)
Regional Tribal Air Information
The Federal Air Rules for Reservations (FARR) requires persons who own or operate certain sources of air pollution on Indian reservations in Idaho, Oregon and Washington to register those sources with EPA and to report air pollutant emissions annually.
On this page:
Do I need to register my facility under the FARR?
Owners and operators of air pollution sources covered under the FARR must register with EPA within 90 days after beginning operation. The following questions will help you determine whether you are required to register:
- Is the air pollution source located within the federally-recognized exterior boundaries of an Indian Reservation? (view maps if you are unsure)
- Does the air pollution source have the potential to emit more than two tons per year of any regulated air pollutant?
- Is the air pollution source not included in the exempt category?
If you answered yes to all three questions, then you must fill out and submit an Initial/Annual Registration Form (PDF) (6 pp, 50K). The following guidance is also available to help you determine if you need to register. You can also call the FARR Hotline at 1-800-424-4372 and ask for assistance.

Who is exempt from registering?
- Air pollution sources that do not have the potential to emit more than 2 tons per year of any regulated air pollutant
- Mobile sources (cars, trucks, boats, trains, etc.)
- Single-family residences and residential buildings with four or fewer apartments or living units
- Air conditioning units used for human comfort and that do not release manufacturing or industrial process pollutants into the air
- Furnaces and boilers used only for space heating with a rated heat input capacity of less than 400,000 British thermal units (Btus) per hour
- Cooking of food, except for wholesale businesses that cook and sell cooked food
- Consumer use of office equipment and products
- Janitorial services and consumer use of janitorial products
- Maintenance and repair activities, except for air pollution sources that maintain and repair equipment as a business
- Agricultural, forestry, and silvicultural activities (including burning)
- Open burning

What is the registration deadline? The owner or operator of an air pollution source, except for Part 71 sources, must register the source with EPA according to the following schedule:
- New air pollution sources must register within 90 days after beginning operation.
- After the initial registration, the owner or operator must re-register by February 15 of each year.
Also:
- Any change of ownership and closures (except for regular seasonal closures) must be reported to EPA within 90 days.
- Any source relocations must be reported to EPA within 30 days.

Forms - Initial source registration and annual re-registration must be submitted using the forms below. Required information includes:
- Facility identification information
- Contact information for persons responsible for source compliance
- Identifying information for all emission units including a facility plot plan
- Descriptions and quantities of fuels and raw materials consumed at the source
- Source operating schedule
- Estimates of total actual emissions
- Estimated efficiencies of air pollution control equipment
All registrations and reports must include a certification signed by the source owner or operator testifying to the truth, accuracy, and completeness of the submittal.

How to do I calculate my emissions? Emissions calculations to be provided in the registration include estimates of PM10 and PM2.5 particulate matter; sulfur oxides; nitrogen oxides; carbon monoxide; volatile organic compounds; lead and lead compounds; ammonia; fluorides; sulfuric acid mist; hydrogen sulfide; total reduced sulfur; and, reduced sulfur compound source emissions. Generally accepted emissions estimating procedures include:
- Source-specific emissions tests
- Mass balance calculations
- Published emissions factors
- Engineering calculations
The basis of all calculations and the calculation itself must be included with the application. For help, you can call the FARR Hotline at 1-800-424-4372 and ask to speak to the FARR Registration Rule Coordinator.

Part 71 Sources - The owner or operator of a Part 71 source must submit an annual registration report to EPA that includes the same registration information and emissions calculations as described for non-Part 71 sources. This annual registration report must be submitted along with the annual emissions report and fee calculation worksheet required for Part 71 sources. A single combined report may be submitted. The first annual registration report for a Part 71 source must be submitted for the calendar year that the source became classified as a Part 71 source.
