On May 7, President Donald Trump issued Executive Order No. 13921, Promoting American Seafood Competitiveness and Economic Growth, stating that it is U.S. policy to “facilitate aquaculture projects through regulatory transparency and long-term strategic planning.” To further this policy, the Order directs the U.S. Army Corps of Engineers to create a nationwide permit for aquaculture operations, and tasks the National Oceanic and Atmospheric Administration with a variety of planning- and permit-related responsibilities.

Over the past 50 years, tremendous progress has been made in reducing air pollution under the Clean Air Act. Nevertheless, while air quality has improved greatly for much of the nation, there are still places where the goal of attaining national standards has still not been reached.

Recent events have called attention to the urgent need for concrete action to address the many problems of these communities.
