Dave Owen, Professor of Law at U.C. Hastings, joins us for this week's Please Explain to discuss the history of clean water legislation and what's at stake as the EPA attempts to roll back established water regulations. A recent executive order issued by President Trump instructed the EPA to review the "Waters of the United States" rule, an Obama-era clean water act that the president criticized for it's "horrible" treatment of small farmers and small businesses. Owen will discuss that 2015 water regulation, as well as the history and impact of the Clean Water Act of 1972 and the Safe Drinking Water Act of 1974.
