40 CFR 61 Subpart M: EPA Asbestos NESHAP

Regulatory citation: Clean Air Act; 40 CFR Part 61, Subpart M, National Emission Standard for Asbestos

What Is the Asbestos NESHAP?

The National Emission Standard for Hazardous Air Pollutants (NESHAP) for asbestos, in 40 CFR Part 61 Subpart M, sets work practices to minimize the release of asbestos fibers during demolition, renovation, and waste handling and disposal. It is issued under the Clean Air Act and is often enforced by state and local air agencies.

Why the Asbestos NESHAP Matters

Disturbing asbestos-containing materials during demolition or renovation can release fibers into the air, putting workers and the public at risk of serious lung diseases. The NESHAP focuses on preventing those emissions.

Core Requirements

1. Inspect Before Work

The owner or operator must thoroughly inspect the facility, or part of it, for asbestos before any demolition or renovation.

2. Know the Thresholds

Renovation requirements apply when regulated asbestos-containing material (RACM) meets certain amounts, generally at least 260 linear feet on pipes, 160 square feet on other facility components, or 35 cubic feet where lengths or areas can't be measured.

3. Notify in Advance

Written notification must generally be given to the delegated agency at least 10 working days before demolition, and before renovation that meets the thresholds. Demolitions require notification even when no asbestos is present.

4. Follow Work Practices

RACM must generally be removed before activities that would disturb it, kept adequately wet during removal, and handled so it doesn't release visible emissions.

5. Dispose Properly

Asbestos waste must be kept wet, sealed in leak-tight containers, labeled, and disposed of at a site that accepts asbestos waste.

6. Have a Trained Person On Site

At least one person trained in the NESHAP requirements must be present during stripping, removing or disturbing RACM.

Common Compliance Approaches

Survey Early

Order an asbestos survey during project planning so findings don't delay work.

Check State and Local Rules

Many states and local agencies have stricter notification and licensing rules.

Coordinate With OSHA Requirements

The NESHAP protects air quality; OSHA's asbestos standards protect workers. Most projects must meet both.

Example: Asbestos NESHAP in Practice

A developer plans to demolish a 1960s office building. A certified inspector finds pipe insulation containing asbestos. The developer submits a notification to the state air agency at least 10 working days before demolition, hires a licensed abatement contractor to remove the insulation first using wet methods, and sends sealed, labeled waste to an approved landfill before demolition begins.

Frequently Asked Questions

Is an asbestos inspection required before demolition?

Yes. Under the asbestos NESHAP, the owner or operator must thoroughly inspect the affected part of the facility for asbestos before demolition or renovation begins.

How much notice is required before demolition?

Written notification must generally be submitted to the delegated agency at least 10 working days before demolition begins. Demolition notifications are required even if no asbestos is found.

Does the asbestos NESHAP apply to homes?

Residential buildings with four or fewer dwelling units are generally not covered, unless they are part of a larger project such as a highway or urban renewal project. State and local rules may still apply.
