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.

On July 1, 2025, OSHA published a proposal to revise OSHA's Inorganic Arsenic standard (29 CFR 1910.1018) in order to reduce compliance burdens, allow for the use of more up-to-date technology, and improve the comprehensibility of the requirements for respiratory protection programs under the standard (90 FR 28267). Part of the intent of this proposal was also to better align this standard with OSHA's Respiratory Protection standard (29 CFR 1910.134). The comment period was scheduled to end on September 2, 2025, but was subsequently extended an additional 60 days to November 1, 2025, in response to requests from the public (90 FR 40545).
At the time of publication of the proposal, OSHA was in the process of appointing members to the Advisory Committee on Construction Safety and Health (ACCSH). OSHA stated in the proposal that it would present this proposed rule to ACCSH once that process was complete and would place the Committee's recommendations on the OSHA website and in the docket for this proposed rule to allow the public to provide comments on those recommendations. OSHA consulted with ACCSH on April 1 and May 19, 2026, and is now reopening the rulemaking record to allow for public comment for an additional 30 days. To read or download the ACCSH recommendations, comments, and other materials submitted in the docket, go to Docket No. OSHA-2025-0016 at www.regulations.gov. Additional materials and information related to OSHA's consultation with ACCSH will be available at https://www.osha.gov/advisorycommittee/accsh/minutes.
