New federal reporting requirements for per- and polyfluoroalkyl substances (PFAS) went into effect on January 1, 2020. The National Defense Authorization Act for FY 2020 (NDAA), signed into law on December 20, 2019, required EPA to add certain PFAS to the federal Toxics Release Inventory (TRI) list of reportable chemicals.

The NDAA identified fourteen specific PFAS chemicals for addition to the TRI list, and directed EPA to add other substances that met two criteria: (1) they were subject to a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) on or before December 20, 2019, and (2) they were identified as active in commerce on the TSCA Inventory that was published in February 2019. Among the new additions are some of the best-known and most-studied substances, including PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonate), and GenX chemicals (including hexafluoropropylene oxide dimer acid).

On January 23, 2020, the Environmental Protection Agency and U.S. Army Corps of Engineers (collectively, “Agencies”) released the pre-publication version of the much-anticipated final rule narrowing the meaning of the term “waters of the United States,” which defines waters subject to federal jurisdiction under the Clean Water Act (“CWA”). The final rule, called the “Navigable Waters Protection Rule,” represents the latest development in the Trump Administration’s extensive effort to repeal and replace the Obama Administration’s 2015 rule redefining the term (“2015 Rule”) and will become effective 60 days after its publication in the Federal Register.

On October 10, 2019, the Environmental Protection Agency (EPA) announced long-awaited proposed revisions to its Lead and Copper Rule (LCR) under the Safe Drinking Water Act. The proposed LCR revisions come nearly 30 years after the federal government last updated its lead and copper testing procedures. Originally promulgated in 1991, the LCR has long been criticized for its imprecise language and has come under fire in recent years in the wake of the water crisis in Flint, Michigan.

For most federal rules, you don’t need a map to figure out in which states they’re the current law.  But you do for the 2015 “Clean Water Rule,” which significantly expanded the reach of the Clean Water Act by redefining the term “waters of the United States.”  That’s one reason why, on September 12, 2019, the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers released a new rule to repeal the Clean Water Rule and restore prior regulations.  This “repeal rule” will take formal effect 60 days after its publication in the Federal Register.

Today the Supreme Court issued its order list from its February 15 Conference during which it considered whether to grant certiorari in two pending petitions regarding discharges of pollutants to groundwater that is hydrologically connected to surface water. The Court granted certiorari in County of Maui, HI v. Hawaii Wildlife

The Supreme Court has declined to review the U.S. Court of Appeals for the Second Circuit’s January 2017 decision in Catskill Mountains Chapter of Trout Unlimited, Inc. et al. v. U.S. EPA reinstating the U.S. Environmental Protection Agency’s (the “EPA”) Water Transfers Rule, meaning the Second Circuit’s decision reinstating the Rule will stand.  The Water Transfer Rule, issued by EPA in 2008, formalized EPA’s historic practice of excluding water transfers between water basins from the Clean Water Act’s (“CWA”) National Pollutant Discharge Elimination System (“NPDES”) permitting requirements after years of legal battles over EPA’s informal policies regarding interbasin transfers.

Earlier this week, the Supreme Court ruled that federal district courts, rather than appellate courts, are the proper venue to challenge the “Waters of the United States” (“WOTUS”) Rule (discussed in a previous blog post here), an Obama-era regulation that expansively defined waters subject to Clean Water Act jurisdiction.  Following the Supreme Court decision, the Eleventh Circuit on Wednesday vacated its 2015 decision which held the opposite.  In doing so, it also remanded a challenge to the WOTUS Rule brought by a coalition of states (led by Georgia) in 2015 in the federal district court in Brunswick, Georgia.

Today, in a much-anticipated decision, the Supreme Court unanimously held that district courts are the proper courts to hear challenges to the “Waters of the United States” (“WOTUS”) Rule, an Obama-era regulation that expansively defined waters subject to Clean Water Act jurisdiction.  The decision overturns a Sixth Circuit ruling that federal appeals courts maintain the proper jurisdiction to hear such challenges.  Writing for the Court, Justice Sotomayor found that “Congress has made clear that rules like the WOTUS Rule must be reviewed first in federal district courts.”
