Wind River Treatment in the Same Manner as a State Approval

On December 6, 2013, EPA approved the Northern Arapaho and Eastern Shoshone Tribes’ application to administer certain non-regulatory provisions of the Clean Air Act on the Wind River Indian Reservation. EPA’s approval will further the Tribes’ Clean Air Act grant funding capabilities, allow them to receive notifications of certain air permits that may affect their airshed, and allow for their participation in air quality commissions and in the development of risk management plans.  More information can be found here.
