On May 30, 2017, the U.S. Court of Appeals for the Ninth Circuit responded to two petitions for review of the U.S. Environmental Protection Agency’s (EPA) conditional registration under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) of a nanosilver pesticide product and vacated that conditional registration. NRDC v. EPA, No. 15-72308. The Natural Resources Defense Council (NRDC), the Center for Food Safety (CFS), and the International Center for Technology Assessment (ICTA) filed petitions in 2015 asking the court to set aside EPA’s final order granting a conditional registration for a nanosilver containing antimicrobial pesticide product named NSPW-L30SWS (NSPW). The court vacated the conditional registration because, according to the court, “EPA failed to support its finding that NSPW was in the public interest.”

In July 2017, the European Commission's (EC) Joint Research Center (JRC) published a report entitled Evaluation of the availability and applicability of computational approaches in the safety assessment of nanomaterials: Final report of the Nanocomput project.

The U.S. Environmental Protection Agency (EPA) made available on May 16, 2017, and requested comment on a draft guidance document, “Guidance on EPA’s Section 8(a) Information Gathering Rule on Nanomaterials in Commerce.” This column discusses the draft guidance.

On July 20, 2017, the Trump Administration published its Unified Agenda of Regulatory and Deregulatory Actions. The Agenda includes a U.S. Environmental Protection Agency (EPA) item (RIN 2070-AJ54) concerning the Toxic Substances Control Act (TSCA) Section 8(a) reporting rule for nanoscale materials.

The U.S. Environmental Protection Agency (EPA) issued on Jan. 12, 2017, a final rule under Section 8(a) of the Toxic Substances Control Act (TSCA) establishing reporting and recordkeeping requirements for certain discrete forms of chemical substances that are manufactured or processed at the nanoscale. This column summarizes the rule.

The May 1, 2017, issue of the U.S. Environmental Protection Agency's (EPA) TechDirect includes an item on the availability of the Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment (NanoRem) Toolbox.

The U.S. Environmental Protection Agency (EPA) finally concluded January 12, 2017, a ten-year effort to issue a Toxic Substances Control Act (TSCA) Section 8(a) rule establishing reporting and recordkeeping requirements for certain discrete forms of chemical substances manufactured or processed at nanoscale. This column summarizes the rule. Reports are due to the EPA no later than May 12, 2018. The final rule is effective May 12, 2017.

The National Institute for Occupational Safety and Health (NIOSH) published a Federal Register notice on February 10, 2017, inviting comment on a proposed information collection plan, "Survey of Engineered Nanomaterial Occupational Safety and Health (OSH) Practices." The goal of the project is to assess the relevance and impact of NIOSH's contribution to guidelines and risk mitigation practices for safe handling of engineered nanomaterials in the workplace. The intended use of the data is to inform NIOSH's research agenda to enhance its relevance and impact on worker safety and health in the context of engineered nanomaterials. 

The Organization for Economic Cooperation and Development (OECD) published a report entitled Alternative Testing Strategies in Risk Assessment of Manufactured Nanomaterials: Current State of Knowledge and Research Needs to Advance Their Use.

On June 22, 2016, President Obama signed the Frank R. Lautenberg Chemical Safety for the 21st Century Act, Pub. L. No. 114-182, and in so doing significantly revised the Toxic Substances Control Act (TSCA) for the first time since its enactment in 1976. This article reviews and analyzes TSCA as amended and focuses narrowly on how new TSCA specifically impacts nanoscale materials. Although the new TSCA dramatically changes how the Environmental Protection Agency (EPA) evaluates and manages industrial chemicals, including nanoscale chemicals, the absence of words or phrases such as nano or nanoscale materials means that there are no specific or additional requirements that apply explicitly to such materials. This was a significant shift from many of the earlier TSCA reform bills, which explicitly addressed nanoscale materials by proposing new definitions such as “substance characteristics” and “special substance characteristics” that included concepts such as size or size distribution; shape; surface structure; and reactivity. The new TSCA is noticeably silent on this subject and does not distinguish nanoscale materials or treat such materials differently from other chemical substances regulated under TSCA.
