Federal Air Rules for Reservations Registration Program


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:
  1. Is the air pollution source located within the federally-recognized exterior boundaries of an Indian Reservation? (view maps if you are unsure)
  2. Does the air pollution source have the potential to emit more than two tons per year of any regulated air pollutant?
  3. 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.

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:

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.
