On May 3, 2023, EPA released its proposed risk management rule under Section 6(a) of the Toxic Substances Control Act (TSCA) to impose restrictions on the manufacture, import, processing, distribution, and use of methylene chloride, a widely-used solvent in a variety of consumer and commercial applications. This is the first risk management rule proposed by

On March 29 the US House of Representatives adopted by voice vote an amendment offered by Reps. Dan Crenshaw (R-TX) and August Pfluger (R-TX) to speed up Environmental Protection Agency (EPA) review of state applications for primacy to run the Class VI Underground Injection Control (UIC) program. The amendment was included in H.R. 1, the Lower Energy Costs Act, the high-profile energy and permitting reform bill the House approved on March 30.

The UIC program is designed to prevent endangerment of underground sources of drinking water from subsurface injections. The Class VI program specifically regulates the geologic sequestration of carbon dioxide, which is considered to be essential for the world to meet international emission reduction targets.

President Biden issued his second veto late last week. The President’s second veto protects a U.S. EPA rule that went into effect on March 20, 2023. That rule redefines “waters of the United States” (WOTUS), and at a high conceptual level, returns the Agency’s interpretation of WOTUS to that of the Obama administration, an interpretation that was revoked and replaced by the Trump administration.

This matter has been hotly contested in the federal courts. Indeed, the U.S. Supreme Court is poised to issue a ruling within the next several weeks on Sackett v. EPA, a decision which could substantially revise and narrow the Agency’s definition of “waters of the United States.” The Court’s decision here could send the Biden administration’s revised definition of WOTUS back to EPA for changes needed in-line with the Court’s decision, if and when issued.

On March 29, 2023, the US Environmental Protection Agency (EPA) published in the Federal Register its long-awaited proposed rule to restrict certain per- and polyfluoroalkyl substances (PFAS) in drinking water under the Safe Drinking Water Act (SDWA). This action is part of EPA’s whole-of-agency approach in its PFAS Strategic Roadmap and is expected to directly affect 66,000 public water systems across the country. Comments on the proposal are due on May 30, 2023. EPA will also hold a public hearing on May 4, 2023 to receive stakeholder input on this important rulemaking.

In late February 2023, EPA released for public comment its Draft Proposed Principles of Cumulative Risk Assessment under the Toxic Substances Control Act (“Draft Principles”), which proposes a set of principles for evaluating cumulative risks for chemicals undergoing risk evaluation under the Toxic Substances Control Act (“TSCA”). In conjunction with the Draft Principles, EPA also released its “Draft Proposed Approach for Cumulative Risk Assessment of High-Priority Phthalates and a Manufacturer Requested Phthalate Under the Toxic Substances Control Act,” (“Draft Proposed Phthalates Cumulative Risk Approach”), an approach for applying these Draft Principles to the evaluation of cumulative risks posed by certain phthalates undergoing TSCA risk evaluations. EPA referred to these documents as the “first steps” towards the Agency conducting cumulative risk assessments under TSCA.

In February 2023, the US Environmental Protection Agency (EPA)’s Office of Enforcement and Compliance Assurance (OECA) quietly released a Compliance Advisory “What You Need to Know about Producing, Distributing, or Selling Pesticide Devices.” The advisory follows on the heels of similar advisories and provides information to the regulated community about requirements for pesticide devices under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) in order to promote compliance. EPA issued this advisory in response to a “significant increase” in the number of pesticide devices being sold or distributed in the US in which EPA has found “substantial non-compliance” with FIFRA requirements. EPA has also experienced a high volume of inquiries from companies and other regulators seeking clarification about pesticide device requirements. The advisory suggests that EPA remains poised to continue taking enforcement actions against companies that import, distribute or sell pesticide devices that do not comply with FIFRA’s requirements.

On December 22, 2022, EPA’s Integrated Risk Information System (IRIS) Program released its ORD Staff Handbook for Developing IRIS Assessments (IRIS Handbook). EPA began working on the approaches in the IRIS Handbook after a 2011 National Research Council report recommended several improvements to the overall IRIS assessment process. In 2020, EPA released a draft IRIS Handbook for public comment and commissioned a peer review by the National Research Council.

Established in 1985 to ensure Agency-wide consistent toxicity evaluations, IRIS assessments provide chemical toxicity values for noncancer and cancer human health effects resulting from chronic exposure to chemicals. These values are often utilized in EPA regulations under the Clean Air Act (CAA), the Safe Drinking Water Act (SDWA), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). While chemical risk evaluations conducted under the Toxic Substances Control Act (TSCA) require more information and analysis than that provided by an IRIS assessment, IRIS assessments will likely continue to be used to inform TSCA risk evaluations. State agencies and international bodies also rely on IRIS assessments.

The US Environmental Protection Agency (“EPA”) announced its enforcement and compliance results for Fiscal Year 2022 (“FY2022”) in late December. In the Annual Results report prepared by EPA’s Office of Enforcement and Compliance Assurance (“OECA”), OECA highlights EPA’s efforts to target the most serious violations of the country’s core environmental statutes and civil rights laws—effectuating the mission and principles set forth in its FY2022 to 2026 EPA Strategic Plan. According to OECA, EPA’s enforcement and compliance program used “a range of tools and best practices” to specifically target water, air, land and chemical violations that impacted communities the most. In so doing, EPA reportedly reduced, treated or eliminated approximately 95 million pounds of pollutants and compelled violators to pay over $300 million in fines, restitution or penalties. The enforcement and compliance trends highlighted below continue an overall decline seen in the last decade, yet provide evidence that EPA is succeeding in its enforcement and compliance efforts in areas that are the biggest priority for the Biden administration.

The Biden-Harris administration is taking new steps to put some teeth into its emphasis on addressing environmental justice. Two recent developments are worth noting given the potential impact on projects and communities. One, EPA announced on September 24, 2022 that it is launching its new Office of Environmental Justice and External Civil Rights (OEJECR or EJ Office). Two, in August 2022, EPA’s Office of General Counsel issued a guidance document entitled Interim Environmental Justice and Civil Rights in Permitting Frequently Asked Questions that outlines EPA’s current views as to how federal, state, and local permitting agencies can meet the requirements of civil rights laws when they are administering environmental permitting requirements.

On August 26, 2022, the US Environmental Protection Agency (EPA) released a pre-publication copy of its much-anticipated proposed rule adding perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) to the list of “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). EPA asserts that this regulatory escalation of PFOA and PFOS will facilitate faster cleanup of contaminated sites and reduce exposures to these “forever chemicals.” If finalized, these hazardous substances designations will have significant and immediate impacts on many industries, from creating new reporting obligations to increased compliance, enforcement, and litigation risks related to site cleanup. EPA’s efforts involving PFOA and PFOS fall within the broader, whole-of-agency approach to addressing PFAS first announced in its PFAS Strategic Roadmap and represent its first ever exercise of its authority under CERCLA section 102(a) to designate a hazardous substance.
