Environmental Protection Agency Administrator Lee Zeldin on Wednesday announced nearly three dozen deregulatory moves that he said would spur the U.S. economy by rolling back rules that have unfairly burdened industry. Many of the moves would affect landmark regulations aimed at protecting clean air and water.

The agency said it would roll back a range of rules and programs, including some that are foundational to its efforts to address climate change. A new WOTUS definition is expected, as well as rollbacks to an emissions reporting program.

A Harvard environmental law expert said the blitz of rollbacks the EPA announced is a "shock and awe routine," and rule changes will face a tough legal path.
