The U.S. Environmental Protection Agency (EPA) has formally withdrawn cybersecurity rules it promulgated in March requiring that states report cybersecurity threats to their public water systems (PWS). The reversal comes in the wake of lawsuits filed in the Eighth Circuit in July by Missouri, Arkansas, and Iowa (the states), along with intervenors American Water Works Association and National Rural Water Association (the water associations). As a result of the withdrawal, the states and water associations filed to dismiss their suits.

Michigan Attorney General (AG) Dana Nessel has filed suit against the Gerald R. Ford International Airport Authority to enforce demands by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) related to alleged per- and polyfluoroalkyl substance (PFAS) contamination of the regional drinking water supply caused by the airport authority.

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 COVID-19 pandemic has elevated fiscal concerns of water and sewer service providers, with many states imposing a moratorium on the collection of delinquent bills and the termination of service. The affordability of water and sewer service has also been a central topic in environmental justice discussions. In the midst of this heightened interest, the United States Environmental Protection Agency (“EPA”) released its long-awaited proposed updates to its Clean Water Act (“CWA”) affordability guidance. The pre-publication version of its 2020 Financial Capability Assessment for CWA Obligations (“2020 FCA”) was released on September 15, 2020. The proposal builds on EPA’s prior guidance, issued in 1997, as well as its 2014 Financial Capability Assessment Framework.  The purpose of the guidance is to establish criteria for EPA consideration of the impact of water quality, stormwater, and drinking water requirements on affordability. This information can then be used to prioritize different regulatory requirements and establish longer compliance schedules in permits and enforcement actions.

As anticipated, the Environmental Protection Agency (EPA) announced on June 18, 2020, that it will not regulate perchlorate, a substance primarily found in rocket fuel and munitions, under the Safe Drinking Water Act (SDWA). Before determining to regulate a chemical or substance under the SDWA, the EPA must consider whether (1) the contaminant may have an adverse effect on the health of persons; (2) the contaminant is known to occur or there is a substantial likelihood that the contaminant will occur in public water systems with a frequency and at levels of public health concern; and (3) in the sole judgment of the Administrator, regulation of such contaminant presents a meaningful opportunity for health risk reduction for persons served by public water systems. 42 U.S.C. § 300g-1(b)(1)(A). In its announcement, the EPA concludes that perchlorate does not meet these criteria for regulation.

The New Jersey Department of Environmental Protection (NJDEP) recently amended its rules under the New Jersey Safe Drinking Water Act (NJ SDWA) to address per- and poly-fluoroalkyl substances (PFAS). NJDEP adopted the amendments on March 31, 2020, and published them in the New Jersey Register on June 1, 2020. 52 N.J.R. 1165(b). The United States Environmental Protection Agency (EPA) began the process for establishing drinking water standards for certain PFAS compounds in February 2020; however, with these amendments, New Jersey now has some of the most stringent PFAS drinking water requirements in the United States.

On February 20, 2020, the U.S. Environmental Protection Agency (EPA) announced its intent to publish a preliminary regulatory determination under the Safe Drinking Water Act (SDWA) for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). Publication will initiate a 60-day notice and comment period that represents the first step toward the adoption of Maximum Contaminant Levels (MCLs) and Maximum Contaminant Level Goals (MCLGs) for PFOA and PFOS, two of the best-understood and most common compounds under the umbrella of perfluoroalkyl substances (PFAS).
