Several stationary air emissions monitors in areas impacted by Hurricane Laura are offline, leaving many concerned about current air pollution levels along the Louisiana and Texas Gulf Coast.
In a 5-to-4 decision, the Supreme Court of Washington State upheld a ruling by a lower court that found that the state’s Department of Ecology (Ecology) exceeded its statutory authority by promulgating a regulation that imposed greenhouse gas (GHG) emissions standards on indirect emitters of those gases.
