The Environmental Protection Agency (EPA) has approved certain parts of Tennessee's plan to manage air quality in the Sullivan County area, specifically those related to controlling sulfur dioxide (SO₂) emissions. This decision follows the state’s efforts to meet federal standards set in 2010, which aim to limit air pollution from new and modified sources. While the EPA is not taking action on all submissions from Tennessee, they have concluded that the state has fulfilled key requirements, including providing a detailed emissions inventory and adhering to rules for reviewing new sources of pollution. This rule takes effect on March 31, 2021.
Simple Explanation
The EPA said that Tennessee made a plan to help clean the air around a place where a factory makes chemicals. They checked and agreed that Tennessee did some important steps, like listing all the polluting stuff, to make sure the air gets better by the end of March 2021.
