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promulgated a WOTUS rule that had been the subject of significant litigation, which the Trump administration had repealed (the “Repeal Rule”).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.

The Environmental Protection Agency (EPA) has initiated two rulemaking actions, both expected to be proposed in early 2022, that could change the way the Clean Water Act (CWA) is administered across the country. Together, these actions would elevate tribal rights in water quality regulatory decision-making and could provide EPA with significantly greater authority to regulate discharges on and upstream of tribal lands.

On August 19, EPA and the Army Corps of Engineers (Corps) issued a joint guidance document concerning implementation of EPA’s 2020 Water Quality Certification Rule. The agencies explain that the guidance applies specifically to 41 Clean Water Act Section 404 Nationwide Permits (NWPs) proposed in September 2020 that have already received certification (or for which certification was denied or waived) but have not yet been finalized, and a more detailed enclosure is intended to be applied generally to the Corps’ permit programs. The guidance also cryptically suggests that the agencies may revisit the 16 NWPs that were previously certified and finalized by the Corps in January 2021. In a press release the following day, EPA and the Corps frame the guidance as addressing “implementation challenges” raised by state and tribal certifying authorities.

On August 13, EPA finalized Clean Water Act (Act) Section 304(a) recommended criteria for phosphorus and nitrogen in lakes and reservoirs. The new recommendations incorporate scientific models that states and tribes with treatment as state status can use to establish numeric water quality criteria for phosphorus and nitrogen, and they mark an important milestone in EPA’s long-running war on excess nutrients in the nation’s surface waters. In the new recommended lakes criteria, EPA is embracing a stressor-response approach to managing nutrients, instead of the least-disturbed reference method. This is a significant move for the agency and has the potential to set a positive precedent going forward for EPA and state and tribal regulators to re-evaluate the utility of the reference method approach in other contexts.

EPA announced yesterday its intent to revise some portions of the 2020 Steam Electric Effluent Limitation Guideline Reconsideration Rule (2020 ELG Rule). EPA’s press release and the pre-publication version of its Federal Register notice sent a clear message that the agency is aiming at membrane technology to control flue gas desulfurization (FGD) wastewater discharges from coal-fired power plants. The notice also states that the agency will reconsider the technology selected for bottom ash transport, and it may revise or eliminate the subcategories created by the 2020 ELG Rule for high-flow facilities, low-utilization facilities, and for facilities that commit to retire or repower coal-fired units by 2028.

There has been a longstanding debate about how to apply the one-year time limit on Clean Water Act Section 401 certification decisions. The D.C. Circuit court in Hoopa Valley Tribe v. FERC, 913 F.3d 1099 (D.C. Cir. 2019) established a bright-line standard that a 401 certification must be issued or denied within one year of receipt of application, or the certification opportunity is waived. States cannot engage in actions to extend this deadline by requiring an applicant to withdraw and refile their application or by finding an application incomplete. This bright-line test was reinforced by the Second Circuit’s more recent decision in New York State Department of Environmental Conservation v. FERC, 991 F.3d 439 (2d Cir. 2021). This interpretation was also codified in EPA’s 2020 Clean Water Act Section 401 Certification Rule. See 85 Fed. Reg. 42210 (July 13, 2020). However, on July 2, the Fourth Circuit offered a different interpretation of Section 401 in its decision in N.C. Department of Environmental Quality v. FERC, No. 20-1655 (McMahan Hydro).

On March 31, U.S. District Judge Christine Arguello found that the Federal Power Act (FPA) is the exclusive authority with regards to controversies related to Federal Energy Regulatory Commission (FERC) -issued hydroelectric licenses, including challenges that stem from the permitting decisions of other federal agencies acting under their independent statutory authority. In Save the Colorado v. Semonite, Civil Action No. 18-cv-03258 (D. Colo. Mar. 31, 2021), the court ruled that it lacked jurisdiction over an appeal of a U.S. Army Corps of Engineers (USACE) Clean Water Act (CWA) Section 404 permit and the associated U.S. Fish and Wildlife Service (USFWS) Endangered Species Act (ESA) biological opinion since these are actions “inhere[d] in the controversy” related to the FERC license.

On May 27, the Environmental Protection Agency (EPA) announced its intent to reconsider the Clean Water Act (CWA) Section 401 final rule issued by the Trump administration in June 2020 (Final Rule).

In an April 1, 2021 ruling, the U.S. Supreme Court overruled Florida’s exceptions to the decision of Special Master Judge Paul Kelly in its long-running dispute with Georgia over the use of water in the Apalachicola-Chattahoochee-Flint (ACF) river basin. The oral argument in the case, held February 22, 2021, seemed to point to several open questions where the justices could have made new law or clarified the tests associated with an equitable apportionment action. However, in the end, it came down to just the content of the evidentiary record, which was not in Florida’s favor, especially with the application of heightened standards of review.
