Louisiana gets a pass on sending sulfur dioxide to other states

US environmental regulators have approved Louisiana's plan for managing sulfur dioxide emissions. This means Louisiana does not have to take further action to prevent its air pollution from affecting neighboring states.

The Clean Air Act requires states to prevent their pollution from harming other states. This approval means Louisiana has convinced federal regulators that its current plan is sufficient. This decision could set a precedent for how other states with similar pollution profiles are assessed.
