On March 13, the Environmental Protection Agency (EPA) took the long-anticipated step of proposing maximum contaminant level goals (MCLGs), as well as individual maximum contaminant levels (MCLs), for six PFAS compounds under the Safe Drinking Water Act. PFAS are a large family of synthetic chemicals that have been in use since the 1940s. Many PFAS have unique physical and chemical properties that make them highly stable and resistant to degradation in the environment, which is why they are sometimes referred to as “forever chemicals.”

The Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (the “Corps”) (together the “Agencies”) have continued working on a proposed rule to revise the definition of “waters of the United States” (WOTUS) under the Clean Water Act (CWA or Act), which will soon move to the next…

Yesterday, EPA announced a proposed rule that would revise the agency’s regulations to include a requirement that water quality standards protect reserved tribal treaty rights. This proposal is a major milestone for the agency that has tried to incorporate reserved tribal treaty rights into its water quality standards program since at least 2015.

On June 1, the Environmental Protection Agency (EPA) released a pre-publication version of its proposal to re-write the Clean Water Act Section 401 rule (Certification Proposal), which, if finalized, is expected to have far-reaching impacts on hydroelectric licensing and relicensing. The Certification Proposal is intended by EPA to replace the version of the rule finalized under the Trump administration in 2020 (2020 Rule). While the Certification Proposal maintains some aspects of the 2020 Rule, it differs in some significant areas and in many ways reverts back to the 1971 regulations.

On December 27, 2021, the U.S. Army Corps of Engineers (Corps) issued a final rule reissuing 40 existing Nationwide Permits (NWPs) with modifications and issuing a new NWP for water reclamation and reuse facilities. The 40 existing NWPs that the Corps reissued includes NWP 17, which authorizes the discharge of dredged or fill material associated with certain small hydroelectric projects.

As the U.S. Environmental Protection Agency (EPA) prepares its Clean Water Act (CWA) Section 401 rule proposal, litigation regarding the 2020 Trump-era rule (Certification Rule) continues. Currently, the issue of whether to re-instate the Certification Rule is proceeding before U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit). The U.S. District Court for the Northern District of California had vacated and remanded the Certification Rule, and intervenors and several states appealed the vacatur. Appellants, including several industry groups, have filed motions to stay the District Court’s vacatur pending the outcome of the appeal and are now awaiting the Ninth Circuit’s ruling that could, at least temporarily, re-instate the Certification Rule.

The Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (the “Corps”) (together the “Agencies”) have continued working on a proposed rule to revise the definition of “waters of the United States” (WOTUS) under the Clean Water Act (CWA or Act), which will soon move to the next stage of agency consideration.[1] The outcome of these rulemaking efforts will impact countless regulated parties, from solar developers to manufacturers, and heavily regulated industry.

On October 21, the U.S. District Court for the Northern District of California vacated and remanded the U.S. Environmental Protection Agency’s (EPA) 2020 Clean Water Act Section 401 final rule (Certification Rule).

In response to the court’s ruling, EPA is implementing the previous water quality certification rule nationwide, which had been in effect since 1971, while it develops a new rule.

Pursuant to Section 401 of the Clean Water Act (CWA), no federal license or permit that may result in a discharge to U.S. waters may be issued unless the state or authorized Tribe, where the discharge will originate, issues a water quality certification or waives the certification requirement.

Landowners and permit applicants received an email notification this week that the Army Corps of Engineers (Army Corps) would not be processing their requests for coverage under a variety of Clean Water Act (CWA) Section 404 Nationwide Permits (NWPs). NWPs are general permits that authorize activities under Clean Water Act Section 404 that “will cause only minimal adverse environmental effects when performed separately, and will have only minimal cumulative adverse effects on the environment.” CWA Section 404 (e)(1).

A recent decision by the U.S. District Court for the District of Arizona vacated and remanded the 2020 Navigable Waters Protection Rule (NWPR) issued by the Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (Corps) (together, “Agencies”) that clarified the scope of federal jurisdictional “Waters of the United States” (WOTUS) under the Clean Water Act (CWA). Before the promulgation of the NWPR, there had been several rulemakings and much litigation on this complicated issue, causing nationwide confusion on the application of a uniform standard. In 2015, the Obama administration promulgated a WOTUS rule that had been the subject of significant litigation, which the Trump administration had repealed (the “Repeal Rule”). The NWPR sought to provide certainty as to which waterbodies meet the features of WOTUS by creating clear categories of jurisdictional waterbodies.
