The Environmental Protection Agency (EPA) is proposing to approve a Tribal Implementation Plan (TIP) submitted by the Northern Cheyenne Tribe. The TIP aims to regulate air pollution on the Tribe's Indian Reservation and tribal trust parcels by maintaining national air quality standards through an open burning program. The plan includes standards for pollutants like sulfur dioxide, particulate matter, and ozone, along with enforcement protocols. The EPA's approval would make these regulations federally enforceable, aligning with the Clean Air Act.
Simple Explanation
The EPA wants to let the Northern Cheyenne Tribe have rules to keep the air clean on their land, and they will use these rules to make sure things like smoke from burning don't get out of hand and make the air bad to breathe.
