California lawmakers on Monday approved one of the most substantial rollbacks of the state’s signature environmental review law in decades, including a controversial exemption that would allow high-tech manufacturing plants to be built in industrial zones with no environmental review.

Gov. Gavin Newsom and state lawmakers scaled back a law that was vilified for its role in California’s housing shortage and homelessness crisis.

Gov. Gavin Newsom, who is lagging far behind his campaign pledge to build millions more homes, was poised Monday evening to sign the most significant rollback in decades to California’s core environmental law that’s long been blamed for construction delays and soaring prices.
