D.C. Circuit Upholds USEPA Decision to Not Require Financial Assurance Under CERCLA for Hardrock Mining

We have previously blogged (in June 2019 and 2017) on a proposed rule released during the final days of the Obama Administration which required hardrock mines to provide financial assurance demonstrating they are able to fund the costs associated with the future cleanup of the mines under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the federal statute designed to address releases of hazardous substances and the cleanup of hazardous waste sites nationwide. In December 2017, the USEPA stated its intention not to issue the final rule, finding that there was no need for any CERCLA financial assurance mechanism for operating hardrock mines based on existing federal and state programs as well as modern mining practices. Several environmental organizations filed suit in the U.S. Court of Appeals for the D.C. Circuit, challenging the USEPA’s decision not to issue the rule.

The Trump administration announced in December 2018 its proposed replacement rule defining “waters of the United States.” Under the proposed rule, the number of wetlands that fall outside of federal jurisdiction is expected to increase.

Phillip Bower and Megan McLean weigh in on what this means for state regulation of non-federal wetlands in the recent

On January 22, 2018, the U.S. Supreme Court unanimously held that challenges to the 2015 Waters of the United States Rule (the “WOTUS Rule” or “Rule”) belong in district court rather than the appellate court. The WOTUS Rule was developed by the U.S. Environmental Protection Agency (“EPA”) and Army Corps of Engineers (“Corps”) to clarify which waters and wetlands fall under federal jurisdiction. Numerous parties challenged the Rule in both federal district courts and circuit courts of appeals. The circuit court actions were consolidated in the Court of Appeals for the Sixth Circuit. In 2016, the Sixth Circuit held that it had jurisdiction to hear petitions related to the legality of the Rule and issued a nationwide stay. This decision was appealed to the Supreme Court by industry groups who argued that, under the plain text of the Clean Water Act, the district courts were the proper jurisdiction.

In an opinion authored by Justice Sonia Sotomayor, the Court noted that the Clean Water Act lists seven specific categories of EPA actions that federal courts of appeals have the exclusive power to review and the Rule did not fall into a category on the list. The Court determined that it had “no basis to depart from the [Clean Water Act]’s plain language” despite arguments by the U.S. government (forwarded by both the Obama and Trump Administrations) that the Rule was “functionally related” to categories on the list and that efficiency, national uniformity, and other policy arguments weighed in favor of making the circuit courts of appeals the appropriate jurisdiction. The Court reversed and remanded the case to the Sixth Circuit, directing the court to dismiss the petitions for review that had been filed.

Because the Supreme Court’s decision was related to jurisdiction and not the merits of the Rule, what does this mean for the Rule’s future?

The Menominee Indian Tribe of Wisconsin has sued the U.S. Environmental Protection Agency (“EPA”) and Army Corps of Engineers (“Corps”) over the proposed Aquila Resources Back Forty Mine, arguing that EPA and Corps have failed to take responsibility for reviewing wetland permits for the project. The lawsuit was expected since the Tribe filed a notice

Since 2001, Wisconsin law has required a permit to discharge fill into wetlands that do not fall under federal jurisdiction (“nonfederal wetlands”). Of the approximately five million acres of wetlands in Wisconsin, an estimated 10 to 30 percent are nonfederal wetlands.

State lawmakers held hearings on December 21 on proposed legislation, AB547/SB600, which would exempt

The U.S. EPA and U.S. Army Corps of Engineers have proposed to delay the effective date of the 2015 Waters of the United States (WOTUS) rule which clarifies which waters and wetlands fall under federal jurisdiction. According to the agencies, the delay is necessary to help avoid confusion among home builders, contractors, and miners.

The 2015 WOTUS rule has an effective date of August 28, 2015, but

Last week, Wisconsin state legislators introduced a proposal to repeal the so-called “moratorium” on the mining of sulfide ore bodies (i.e., mineral deposits in which nonferrous metals are mixed with sulfide minerals) in Wisconsin. The state law in question was enacted in 1998 over concerns that sulfide minerals exposed during mining activities can react with air and water to form acid drainage which can pollute groundwater and harm lake and stream life.

The moratorium is actually a requirement that prohibits
