The proposed rule is available at the Federal eRulemaking Portal, <E T="03">https://regulations.gov.</E> This proposed rule would codify technical specifications and working conditions in MSHA standards to allow the use of electronic surveying equipment in underground gassy mines. The public comment period for this proposed rule was scheduled to close on July 31, 2025, 30 days after publication of the proposed rule. MSHA received a request from a commenter for an extension of the comment period so that commenters could properly review, research, and develop meaningful comments. The commenter asked for an additional 60 days. After reviewing the comment, MSHA has determined that it is appropriate to extend the public comment period until September 2, 2025, in order to provide stakeholders and interested parties with an additional 30 days to review the proposal and prepare comments. <SIG> <NAME>James P.
