The Environmental Protection Agency (EPA) has issued significant new use rules (SNURs) for certain chemicals under the Toxic Substances Control Act (TSCA). These rules require companies to notify the EPA 90 days before manufacturing or processing these chemicals for any newly designated significant uses. The purpose is to allow the EPA to assess potential risks and take necessary actions before these activities start. Businesses that want to use these chemicals in a significant new way must submit a Significant New Use Notice (SNUN) and wait for EPA review and approval.

The Internal Revenue Service, part of the Treasury Department, announced a notice requesting public comments on a petition to add potassium bicarbonate to the list of substances subject to a Superfund tax. The petition, submitted by the Occidental Chemical Corporation, proposes adding potassium bicarbonate, used in cattle feed, glass manufacturing, as a food additive, and a pharmaceutic ingredient, to the taxable list under the Internal Revenue Code. The petition details its classification numbers, composition, and the production process. The public is invited to provide feedback by March 24, 2025, either online or by mail, as outlined in the notice.

The Environmental Protection Agency (EPA) has finalized a rule under the Toxic Substances Control Act (TSCA) requiring manufacturers to submit unpublished health and safety studies on 16 specific chemicals. This rule, effective January 13, 2025, aims to collect important data to help the EPA understand potential risks associated with these chemicals and manage them appropriately under TSCA guidelines, especially for prioritization and risk evaluation purposes. The rule includes details on which studies need to be reported, exemptions, and how to submit the information; it is intended to address market failures by ensuring the EPA can make informed decisions based on actual data rather than assumptions.

The Environmental Protection Agency (EPA) is proposing new rules for the use of certain chemical substances under the Toxic Substances Control Act (TSCA). These rules, known as Significant New Use Rules (SNURs), require entities to notify EPA at least 90 days before starting activities considered significant new uses of these chemicals. The EPA will then assess these uses for potential risks. The proposed rules aim to ensure new chemical substances are safely manufactured and processed, protecting human health and the environment.

The Environmental Protection Agency (EPA) is proposing new rules under the Toxic Substances Control Act (TSCA) for certain chemical substances previously submitted for premanufacture notices. These rules, known as Significant New Use Rules (SNURs), will require any person planning to manufacture or process these chemicals in a way that has been identified as a significant new use to notify the EPA at least 90 days before starting. This allows the EPA to assess the potential risks and decide on any necessary actions before the activity begins. Additionally, the chemicals must not be manufactured or processed for these new uses until they receive EPA approval.

The Environmental Protection Agency (EPA) has issued new rules under the Toxic Substances Control Act (TSCA) for certain chemical substances identified in premanufacture notices (PMNs). These rules, known as Significant New Use Rules (SNURs), require companies to notify the EPA 90 days before beginning to manufacture or process these chemicals in ways considered a "significant new use," giving the EPA time to evaluate potential risks. The rules include specific requirements for workplace safety, such as ventilation and protective equipment, as well as guidelines for hazard communication. This regulation aims to prevent risks to human health and the environment before these new uses of chemicals are fully developed or used commercially.
