The Department of Environmental Quality proposed amendments to regulations governing the incorporation by reference of federal air quality regulations. The amendments would update references to the Code of Federal Regulations and the U.S. Code, including, among other things, incorporating the North American Industry Classification System of 2022, reflecting the transfer of rulemaking authority from the Board of Environmental Review to the Department, and aligning with current industry standards and EPA guidelines. Comments are due July 8, 2024. See https://sosmt.gov/docs/118/2024/64310/issue-11-june-7-2024 (pp. 1278-87).
