OSHA Reopens Asbestos Rulemaking - 30 More Days for Comment

OSHA reopened the rulemaking record on its proposal to revise the agency’s asbestos standards, announcing an additional 30-day public comment period on July 22, 2026. The reopening follows consideration of the rulemaking by OSHA’s Advisory Committee on Construction Safety and Health (ACCSH). The Federal Register notice contains the full details, including the exact comment deadline and submission instructions.

What OSHA Announced

This is a procedural step in an active rulemaking, not a change to the standards themselves. The key points:

  • Status: OSHA has proposed revising its asbestos standards. The proposal is not final.
  • New development: The record is reopened for an additional 30 days of public comment following ACCSH review.
  • Effect on current requirements: None. The existing OSHA asbestos standards remain in force exactly as written.

What this means in practice: nothing about your compliance obligations changes today. The permissible exposure limit, excursion limit, work classifications, and monitoring requirements all stay where they are until OSHA finalizes a rule. For the current numeric values, see our asbestos regulatory standards quick reference.

How This Affects Asbestos Work Now

Abatement Contractors and Project Designers

Continue running projects under the existing standards. Work practice classifications, negative exposure assessments, and respiratory protection requirements are unchanged. If your firm has field experience with provisions of the current standards that work poorly in practice, the reopened comment period is the mechanism to say so on the record.

Air Monitoring and Industrial Hygiene

Personal and area monitoring protocols do not change. PCM (Phase Contrast Microscopy) analysis under the current OSHA reference method remains the compliance basis for exposure monitoring. Our asbestos air monitoring guide covers the current framework.

Building Inspectors and Consultants

Inspection and survey obligations under AHERA (Asbestos Hazard Emergency Response Act) and the asbestos NESHAP (National Emission Standards for Hazardous Air Pollutants) are separate regulatory programs and are not part of this OSHA rulemaking. Pre-demolition surveys, notifications, and disposal requirements continue unchanged.

Ohio note: Ohio’s asbestos hazard abatement program, administered through state licensing and certification requirements, operates independently of the OSHA worker protection standards. An eventual OSHA revision would affect worker exposure requirements on Ohio job sites, but it would not alter Ohio’s contractor licensing, notification, or disposal rules. See our Ohio asbestos regulations overview for how the state program fits together.

What to Watch

The comment period runs 30 days; check the Federal Register notice for the exact closing date. After the record closes, OSHA will review comments and ACCSH input before deciding whether to proceed to a final rule, revise the proposal, or take other action. There is no announced timeline for a final rule, and no effective date exists because nothing has been finalized.

What to Do Now

If you perform asbestos work or manage asbestos compliance:

  • Read the Federal Register notice and note the comment deadline.
  • Submit comments if the proposed revisions would affect your field operations, monitoring costs, or work practices.
  • Keep all current monitoring, work practice, and recordkeeping procedures in place. Do not change protocols based on a proposal.
  • Confirm your team is working from the current standards, not draft language circulating from the proposal.
