{"abstract":"The National Institute for Occupational Safety and Health (NIOSH) of the Centers for Disease Control and Prevention (CDC) intends to evaluate the scientific data on engineered nanomaterials (ENMs) to develop categorical occupational exposure limits (OELs) based on the available scientific evidence regarding the hazard or safety of these materials. NIOSH seeks to obtain materials, including published and unpublished reports and research findings, to evaluate the possible adverse health risks of occupational exposure to ENMs.","action":"Request for information.","agencies":[{"raw_name":"DEPARTMENT OF HEALTH AND HUMAN SERVICES","name":"Health and Human Services Department","id":221,"url":"https://www.federalregister.gov/agencies/health-and-human-services-department","json_url":"https://www.federalregister.gov/api/v1/agencies/221","parent_id":null,"slug":"health-and-human-services-department"},{"raw_name":"Centers for Disease Control and Prevention","name":"Centers for Disease Control and Prevention","id":44,"url":"https://www.federalregister.gov/agencies/centers-for-disease-control-and-prevention","json_url":"https://www.federalregister.gov/api/v1/agencies/44","parent_id":221,"slug":"centers-for-disease-control-and-prevention"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2019/12/17/2019-27169.html","cfr_references":[],"citation":"84 FR 68935","comment_url":null,"comments_close_on":"2020-02-18","correction_of":null,"corrections":[],"dates":"Electronic or written comments must be received by February 18, 2020.","disposition_notes":null,"docket_ids":["CDC-2019-0111, NIOSH-332"],"dockets":[{"supporting_documents":[],"agency_name":"CDC","documents":[{"comment_count":2,"comment_start_date":"2019-12-17","updated_at":"2023-02-28T13:53:26.398-05:00","comment_url":"https://www.regulations.gov/commenton/CDC-2019-0111-0001","allow_late_comments":null,"id":"CDC-2019-0111-0001","comment_end_date":"2020-02-19","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"CDC-2019-0111","title":"Request for Information on Toxicological and Physicochemical Data of Engineered Nanomaterials to Evaluate in Developing Categorical Occupational Exposure Limits (OELs).
