Mintz Member Jeff Porter Discusses Notable Environmental Law, Policy and Cases to Watch In 2019
July 10, 2019
In a July 12 article, Mr. Porter discussed one of the biggest environment-related regulations to watch in the second half of 2019.
In particular, he commented on the EPA’s new narrower definition of "waters of the U.S." under the Clean Water Act, which is expected to be finalized by December. “Just as the Obama rule was challenged in court by various states and industry groups, the Trump rule will face its own legal battles,” Mr. Porter said.
In a July 8 article, Mr. Porter discussed one of the most significant rulings in environmental law during the first half of 2019.
In particular, he commented on the U.S. Supreme Court’s ruling to limit courts' ability to defer to federal agencies' interpretations of their own regulations. “With their newfound leeway, judges could begin to wade more deeply into controversial and science-heavy issues like climate change and water quality disputes,” Mr. Porter said.
