On July 29, 2025, the US Environmental Protection Agency (EPA) issued the final significant usage rules (snur) for certain chemical substances, including graphen nanoplats (generic), the subject of preparatory awareness (PMN) and a microbial commercial activity proof (MCAN) and an order that is ordered was granted, the EPA order from the TSCA). 90 fed. Regs 35624. The snurs require people who intend to produce one of the chemical substances for an activity (including import) or process, which is referred to as significant new use to notify the EPA at least 90 days before the start of this activity. The EPA states that the manufacture or processing for significant new use may only begin when the EPA has carried out the necessary notification, an appropriate determination regarding this notification has taken and taken the measures required by this provision. The final snurs will be effective September 29, 2025.
EPA states that the chemical substance, which was generally identified as graphic nanoplatelettes (PMN P-22-54), are reported for the significant new uses described below. EPA notes that the requirements do not apply to quantities of the substance after it has been completely reacted or cured. Or embedded in a permanent solid polymer shape, which should not be subjected to further processing, except for mechanical processing or physical mix. The important new uses are:
- Protection at the workplace: Requirements according to 40 CFR section 721.63 (a) (1) and (3)-(5), (b) and (c). When determining which people are likely to be exposed according to section 721.63 (a) (1) and (4), technical control measures (tailor -made measures arefor exampleHousing or restriction of the company, general and local ventilation) or the administrative control measures (measures to combat administrative control (for exampleJob guidelines and procedures) are taken into account and implemented to prevent exposure, as far as possible. For the purposes of section 721.63 (a) (5), the respiratory protection areas must be a National Institute for Occupational Safety and Health (NIOSH) assigned protection factor (APF) of at least 50. For the purposes of Section 721.63 (b), the concentration is set to 1.0 percent.
- Dangerous communication: Requirements according to 40 CFR section 721.72 (a)-(f), (g) (1), (G) (3) (III) and (G) (5). For the purposes of section 721.72 (e), the concentration is set to 1.0 percent. For the purposes of section 721.72 (g) (1), this substance can cause a specific target organ toxicity. Alternative danger and warning statements that meet the criteria of the globally harmonized system of classification and identification of chemicals (GHS) and the US and health administration of US security (OSHA) (HCS).
- Industrial, commercial and consumer activities: Requirements according to 40 CFR section 721.80 (K), (V) (3) and (X) (3). It is a significant new use to produce the substance than by importing to the USA in the form of a solution (ieno domestic production). It is a significant new use to process the substance in any way that creates an inhalation exposure. It is a significant new use to use the substance in an application method in which the concentration of the substance in the formulation exceeds the confidential concentration listed in the order.
- Release to water: Requirements according to 40 CFR section 721.90 (a) (1), (b) (1) and (c) (1).
The above -mentioned provisions apply as well as changed below:
- Records: Recording requirements, as stated in 40 CFR section 721.125 (a)-(i) and (K), apply to manufacturers, importers and processors of this substance; And
- Restriction or revocation of certain notification requirements: The provisions of Section 721.185 apply.
