To address the identified unreasonable risk, EPA is proposing requirements to, among other things, prevent consumer access to the chemical, restrict the industrial and commercial use of the chemical while also allowing for a reasonable transition period where an industrial and commercial use of the chemical is being prohibited, and protect workers from the unreasonable risk of 1-BP while on the job.","document_number":"2024-17204","html_url":"https://www.federalregister.gov/documents/2024/08/08/2024-17204/1-bromopropane-1-bp-regulation-under-the-toxic-substances-control-act-tsca","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-08-08/pdf/2024-17204.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-17204.pdf?1723034721","publication_date":"2024-08-08","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"excerpts":"would warrant additional <span class=\"match\">monitoring</span>, which is also described.

NMP is a widely used solvent in a variety of industrial, commercial, and consumer applications including the manufacture and production of electronics such as semiconductors, polymers, petrochemical products, paints and coatings, and paint and coating removers.

Additional adverse effects associated with exposure to NMP include liver toxicity, kidney toxicity, immunotoxicity, neurotoxicity, skin irritation, and sensitization. To address the identified unreasonable risk, EPA is proposing to: prohibit the manufacture (including import), processing, and distribution in commerce and use of NMP in several occupational conditions of use; require worker protections through an NMP workplace chemical protection program (WCPP) or prescriptive controls (including concentration limits) for most of the occupational conditions of use; require concentration limits on a consumer product; regulate certain consumer products to prevent commercial use; and establish recordkeeping, labeling, and downstream notification requirements.","document_number":"2024-12643","html_url":"https://www.federalregister.gov/documents/2024/06/14/2024-12643/n-methylpyrrolidone-nmp-regulation-under-the-toxic-substances-control-act-tsca","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-06-14/pdf/2024-12643.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-12643.pdf?1718282716","publication_date":"2024-06-14","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"excerpts":"use where <span class=\"match\">inhalation</span> and dermal <span class=\"match\">exposures</span> both significantly contribute to the unreasonable risk, EPA is proposing <span class=\"match\">inhalation</span> and dermal <span class=\"match\">exposure</span> controls.

TCE is widely used as a solvent in a variety of industrial, commercial and consumer applications including for hydrofluorocarbon (HFC) production, vapor and aerosol degreasing, and in lubricants, greases, adhesives, and sealants. TSCA requires that when EPA determines a chemical substance presents unreasonable risk that EPA address by rule the unreasonable risk of injury to health or the environment and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. EPA determined that TCE presents an unreasonable risk of injury to health due to the significant adverse health effects associated with exposure to TCE, including non-cancer effects (liver toxicity, kidney toxicity, neurotoxicity, immunotoxicity, reproductive toxicity, and developmental toxicity) as well as cancer (liver, kidney, and non-Hodgkin lymphoma) from chronic inhalation and dermal exposures to TCE. TCE is a neurotoxicant and is carcinogenic to humans by all routes of exposure. The most sensitive adverse effects of TCE exposure are non-cancer effects (developmental toxicity and immunosuppression) for acute exposures and developmental toxicity and autoimmunity for chronic exposures. To address the identified unreasonable risk, EPA is proposing to: prohibit all manufacture (including import), processing, and distribution in commerce of TCE and industrial and commercial use of TCE for all uses, with longer compliance timeframes and workplace controls for certain processing and industrial and commercial uses (including proposed phaseouts and time-limited exemptions); prohibit the disposal of TCE to industrial pre-treatment, industrial treatment, or publicly owned treatment works, with a time-limited exemption for cleanup projects; and establish recordkeeping and downstream notification requirements.","document_number":"2023-23010","html_url":"https://www.federalregister.gov/documents/2023/10/31/2023-23010/trichloroethylene-tce-regulation-under-the-toxic-substances-control-act-tsca","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2023-10-31/pdf/2023-23010.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2023-23010.pdf?1698669915","publication_date":"2023-10-31","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"excerpts":"and chronic <span class=\"match\">inhalation</span> and dermal <span class=\"match\">exposures</span>, as well as cancer (liver, kidney, and non-Hodgkin lymphoma) for chronic <span class=\"match\">inhalation</span> and dermal <span class=\"match\">exposures</span>.
