Enforcement Exemptions and Limitations Under the Appropriations Act

Archived. OSHA updated CPL 02-00-051 in 2024 and changed the document number to CPL 02-00-170. This update was adopted by the OSH Division 12/13/2024.

This instruction applies statewide and was originally effective on May 28, 1998. The NAICS code appendix is updated annually and contains data generally published by the Bureau of Labor Statistics (BLS) the previous fall, which is based on data from the previous full calendar year. For example, 2022 industry injury/illness data was published by BLS in November 2023 and OSHA published the updated Appendix in January 2024. The effective date of Appropriations Act as it relates to the current list of NAICS codes is effective the day after BLS publishes the annual data.

History Note: OSHA contacted all state plans on April 11, 2024, to inform them, going forward, that the effective date for the Appropriations Act will be the day after the BLS releases their data, not the date of OSHA’s annual memo as it was in previous years. The cover sheet was updated on the date of signature, but the effective date is November 9, 2023.
