RACM definition

Regulated asbestos-containing material includes friable asbestos, Category I nonfriable that became friable or was sanded, ground, cut, or abraded, and Category II nonfriable likely to crumble under expected forces.

NESHAP asbestos citation

The federal asbestos NESHAP is 40 CFR Part 61, Subpart M, which sets work practice standards for demolition and renovation of facilities containing regulated asbestos-containing material.

Renovation threshold

A renovation is regulated when at least 160 square feet of facility components, 260 linear feet of pipes, or 35 cubic feet of material will be disturbed.

Category I nonfriable

Category I nonfriable ACM includes packings, gaskets, resilient floor covering, and asphalt roofing products; it becomes regulated when friable or when sanded, ground, cut, or abraded.

Category II nonfriable

Category II nonfriable ACM is any nonfriable asbestos material other than Category I, such as asbestos cement products, and is regulated when likely to be crumbled or pulverized.

Demolition notification trigger

Demolition of a public or commercial facility is regulated regardless of asbestos quantity; residential buildings with four or fewer dwelling units are generally exempt unless part of a larger regulated project.

Pre-work inspection duty

The owner or operator must inspect for asbestos, by sampling and analysis or documented assumption, before any renovation or demolition begins and must keep the record available.

Order of work rule

All RACM must be removed before any activity that would disturb it, and before demolition of the structure, except where removal is impossible or would create a greater hazard.

AHERA accreditation disciplines

AHERA recognizes five disciplines: inspector, management planner, project designer, contractor/supervisor, and worker; each requires a training course, an exam, and periodic refresher training.

Refresher training interval

Accredited asbestos professionals, including inspectors, management planners, project designers, contractor/supervisors, and workers, must complete refresher training annually to maintain accreditation.

Inspector role

An accredited inspector locates and samples suspect material, documents homogeneous areas, and records the condition and quantity of asbestos-containing material found in a building.

Management planner role

An accredited management planner interprets inspection findings, assesses hazards, and develops response actions and an asbestos management plan for a school building.

Bulk sampling minimums

Sampling typically requires at least three samples per homogeneous area of surfacing material or thermal system insulation and at least two per miscellaneous material.

NVLAP laboratory analysis

Bulk samples are analyzed by an accredited laboratory, commonly using polarized light microscopy, and the report states the asbestos percentage and fiber type detected.

Presumed asbestos material

Thermal system insulation and surfacing material in older buildings are presumed to contain asbestos unless sampled and shown otherwise, and the presumption must be communicated to occupants and employees.

On-site supervisor requirement

An accredited contractor/supervisor must be present at the work site at all times while abatement is performed, and accreditation records must be available on site.

Ten working day notice

The owner or operator must submit written notification of renovation or demolition to the delegated agency at least 10 working days before work begins.

Notification contents

Notification states the owner/operator identity, facility location and description, estimated RACM quantity, scheduled start and completion dates, and the waste disposal site name and address.

Twenty percent revision rule

A revised notification is required if the start date changes or if the amount of RACM to be removed changes by more than 20 percent from the original estimate.

Emergency renovation notice

Emergency work caused by a sudden event may begin without the 10-working-day wait, but notification must be made as soon as possible and before the next working day.

Ordered demolition

A demolition ordered by a government agency because a structure is structurally unsound and in imminent danger of collapse requires notification as soon as possible rather than 10 working days ahead.

Delegated program control

Where a state or local agency has been delegated NESHAP authority, its rules govern and may be more stringent than the federal requirements, including notice timing and content.

Disposal site in notice

The notification must identify the permitted waste disposal site that will receive the asbestos waste, and a change of disposal site requires a revised notification.

Notified work window

Work may not begin before the notified start date and must finish by the notified completion date; changes to either date require a revised notification.

Daily project log

A daily log records dates and hours worked, areas abated, quantity of material removed, and waste generated, providing evidence that work stayed within the notified window.

On-site document set

Site records include the notification and amendments, inspection and sampling results, worker and supervisor accreditation certificates, the work plan, daily logs, and waste shipment records.

OSHA exposure limit

OSHA 29 CFR 1926.1101 sets a permissible exposure limit of 0.1 fibers per cubic centimeter as an 8-hour time-weighted average for asbestos work.

Duration reconciliation

Waste shipment dates, manifest numbers, and disposal receipts should show that all removed material left the site before the notified completion date.

Record availability

Notification, inspection, and waste records must be kept and made available to the EPA Administrator on request, and delegated states may require longer retention.

Waste packaging rule

Asbestos waste must be wetted, sealed in leak-tight bags or wrapped containers, labeled with the required warning, and kept sealed until it reaches the permitted disposal site.

Manifest copies

The generator, transporter, and disposal site each retain a manifest copy; the disposal site returns a signed copy to the generator as proof of receipt.

Missing receipt follow-up

If a signed disposal receipt is not returned within the interval set by the delegated program, the generator must investigate the discrepancy and document the follow-up.

Quantity reconciliation

Shipped waste quantities on manifests should be compared with the RACM amount estimated in the notification; unexplained differences are a common inspection finding.
