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).

New federal reporting requirements for per- and polyfluoroalkyl substances (PFAS) went into effect on January 1, 2020. The National Defense Authorization Act for FY 2020 (NDAA), signed into law on December 20, 2019, required EPA to add certain PFAS to the federal Toxics Release Inventory (TRI) list of reportable chemicals.

The NDAA identified fourteen specific PFAS chemicals for addition to the TRI list, and directed EPA to add other substances that met two criteria: (1) they were subject to a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) on or before December 20, 2019, and (2) they were identified as active in commerce on the TSCA Inventory that was published in February 2019. Among the new additions are some of the best-known and most-studied substances, including PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonate), and GenX chemicals (including hexafluoropropylene oxide dimer acid).
