This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
FederalRegister.gov retrieves relevant information about this document from Regulations.gov to provide users with additional context. This information is not part of the official Federal Register document.

Request for information.
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NIOSH seeks to obtain materials, including published and unpublished reports and research findings, to evaluate the possible adverse health risks of occupational exposure to ENMs.
Electronic or written comments must be received by February 18, 2020.
You may submit comments, identified by CDC-2019-0111 and Docket Number NIOSH-332, by either of the two following methods:
Instructions: All information received in response to this notice must include the agency name and docket number [CDC-2019-0111; NIOSH-332]. All relevant comments received will be posted without change to http://www.regulations.gov, including any personal information provided. All electronic comments should be formatted in Microsoft Word. Please make reference to CDC-2019-0111 and Docket Number NIOSH-332.

In 2017, NIOSH contributed to the International Organization for Standardization (ISO) technical report on frameworks for developing OELs for nano-objects [ISO 2016]. In 2019, NIOSH published a Technical Report on occupational exposure banding guidance [NIOSH 2019]. The information presented in these Technical Reports represents the most recent update of the scientific rationale and methodology for establishing hazard values for chemicals, which includes ENMs.
The development of an OEL for an individual chemical involves a critical review of the available scientific data in humans and animals to identify relevant studies and to characterize the various lines of evidence that can support the derivation of the OEL. NIOSH requests information for ENMs to include human, animal, and cellular toxicology data, including but not limited to: Acute, subchronic, or chronic data; the physicochemical characterization of those ENMs; and other information about the biological mechanisms and ( printed page 68936) toxicological effects of ENMs. NIOSH is also seeking information on studies that include evaluating the dose-response relationships between exposure to ENMs and the development of adverse lung effects including inflammation, fibrosis, or neoplasia. Supporting information for published studies should include a full citation. For unpublished studies please include authors, affiliations, year, and any context on how the data were collected.
NIOSH will publish a Technical Report which describes the data, methods, and findings for the development of categorical OELs for ENMs, which may include relevant information submitted in response to this request. The draft Technical Report will be made available for public comment in a subsequent notice.
