Biden Administration Publishes Final Rule Redefining “Waters of the United States”

On January 18, 2023, the Biden administration published its Final Rule revising the definition of “Waters of the United States” (WOTUS) under the Clean Water Act (CWA). Wetlands and waterways that meet the definition of WOTUS are protected by the CWA and subject to the U.S. Environmental Protection Agency’s and Army Corps of Engineers’ jurisdiction. However, the term is not defined in the statute. As such, the federal agencies’ interpretation of WOTUS determines which waters are subject to the CWA permitting requirements.

U.S. Environmental Protection Agency Proposes Updates to State Certification Process Under Clean Water Act Section 401

A recently proposed rule by the U.S. Environmental Protection Agency (EPA) seeks to expand the powers of states and tribes in approving or denying projects that require Clean Water Act (CWA) authorization. On June 9, 2022, EPA published for public comment its proposed Clean Water Act Section 401 Water Quality Certification Improvement Rule, which would significantly alter a Trump-era rule regarding the grounds on which state and tribal certifying agencies may impose conditions on, or outright block, projects that receive federal authorization.

House Introduces PFAS Action Act of 2021

On Tuesday, April 13, Reps. Debbie Dingell and Fred Upton, both D-Mich., introduced the PFAS Action Act of 2021, seeking further regulation of per- and polyfluorinated substances (PFAS). Most notably, the bill would require the U.S. Environmental Protection Agency (EPA) to take action to address two PFAS chemicals — PFOA and PFOS — through a number of regulatory provisions: designating PFOA and PFOS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act, designating PFOA and PFOS as hazardous air pollutants under the Clean Air Act, and requiring EPA to establish national drinking water standards for PFOA and PFOS.

U.S. Army Corps of Engineers Finalizes 16 Nationwide Permits

On January 5, 2021, the U.S. Army Corps of Engineers (Corps) released a prepublication version of its final rule reissuing and modifying 12 existing Nationwide Permits (NWPs) and issuing four new NWPs. NWPs authorize activities under Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act of 1899 when those activities will result in “minimal individual and cumulative adverse environmental effects.” In addition to finalizing 16 NWPs, the rule also changed general conditions and definitions associated with those NWPs. Through this action, the Corps did not reissue or modify the remaining 40 existing NWPs, which will remain in effect until March 18, 2022.

Environmental Protection Agency Issues Interim Strategy Memorandum to Address PFAS in Federally Issued Water Permits

The U.S. Environmental Protection Agency (EPA) Office of Water has published a new interim strategy memorandum for addressing per- and polyfluoroalkyl substances (PFAS) in National Pollutant Discharge Elimination System (NPDES) permits issued by EPA. The memorandum includes recommendations generated by a cross-agency workgroup, which conducted a review of existing Clean Water Act (CWA) section 402 NPDES permitting authorities to determine where and how currently unregulated contaminants like PFAS may fit into the permitting process. Under the CWA, the NPDES permit program regulates point sources that discharge pollutants into waters of the United States. Currently, there are no CWA water quality criteria or effluent guidelines for PFAS, an umbrella category of thousands of synthetic chemicals historically used in industrial manufacturing processes for their flame-resistant and nonstick properties.
