On Sept. 25, Minnesota Gov. Tim Walz asked the Minnesota Pollution Control Agency (MPCA) to initiate the process to establish a Clean Cars Minnesota Rule, which would set both a low-emission vehicle (LEV) standard and a zero-emission vehicle (ZEV) standard. Next month, the MPCA will begin its rulemaking process, with a goal of adopting a final rule by December 2020. If implemented, Minnesota would join 14 states with an LEV standard, 11 of which also have a ZEV standard.

The Minnesota plan is modeled after California LEV and ZEV standards. California has a nearly 50-year-old waiver under the Clean Air Act permitting the state to set stricter emission standards. After indications that the federal government would publish a rule revoking the waiver, California, joined by 22 other states, including Minnesota, and the District of Columbia filed a lawsuit seeking to enforce states’ rights to set emission standards more stringent than those imposed by the federal government. The lawsuit presents novel questions under the Clean Air Act including whether a waiver can be revoked, and if so, under what circumstances. Any final rule in Minnesota will be contingent on states retaining the right to adopt more restrictive measures, including through the operative waiver under Sections 209(b) and 177 of the Clean Air Act.

On Sept. 12, 2019, the U.S. Environmental Protection Agency and the Department of the Army followed through on an early Trump administration promise to repeal a 2015 jurisdictional rule defining the scope of the government’s authority under the Clean Water Act. See Definition of “Waters of the United States”—Recodification of Pre-Existing Rules (pre-publication version).

Dubbed the “Waters of the United States” (WOTUS) rule, the Obama-era regulation spawned a tide of litigation, in federal trial and appellate courts, challenging the WOTUS rule as an unlawful attempt by the EPA and the Corps of Engineers to increase the numbers and kinds of waters subject to permitting requirements. The U.S. Supreme Court ultimately weighed in, saying that challenges to the WOTUS rule belong in the federal districts courts, not the U.S. courts of appeals. National Association of Manufacturers v. Department of Defense, __ U.S. __, 138 S.Ct. 617 (2018).
