The Contractor Who Showed Up With the Wrong Credentials
A K-12 district solicits bids to remove 400 linear feet of friable boiler insulation and 1,200 square feet of vinyl asbestos floor tile from a 1955 high school. The low bidder submits: a state contractor license, a supervisor certificate for the supervisor, and a letter saying its four workers 'have been doing this for years.' The district's business manager asks the AHERA inspector whether the bid can be awarded. Separately, the district plans to have its own maintenance staff remove the floor tile during summer break to save money, arguing tile is 'non-friable so AHERA doesn't apply.'
1. What credentials must the abatement contractor and its workers hold, and what federal/state requirements apply?
Read the worked answer
The contractor must be a certified asbestos contractor under the state's AHERA/ASHARA program (40 CFR 763 Subpart E and the ASHARA amendments), and the on-site supervisor must hold a valid supervisor certificate. Each worker who will disturb the ACBM must hold a valid worker certificate from an accredited training program (763.90 requires abatement be done by accredited persons; 763.92 requires training). 'Years of experience' is not a credential. The district should verify certificates, confirm the training provider is accredited, and check expiration dates.
Other requirements: NESHAP (40 CFR 61 Subpart M) - the 400 LF of friable insulation is well above the 260 LF/35 ft³ threshold, so a written notification to the EPA/state at least 10 working days before starting is required; the tile may also count if it will be sanded/ground or is in poor condition. OSHA construction standard 29 CFR 1926.1101 applies to the contractor's employees. State law may impose additional licensing and notification. The bid should not be awarded until the contractor demonstrates compliant worker and supervisor certification.
2. Evaluate the district's plan to have its own maintenance staff remove the floor tile.

The premise is wrong. 'Non-friable' does not mean 'outside AHERA.' Under 40 CFR 763.90, an LEA may use its own employees for small-scale, short-duration response actions only if the employees are accredited (trained and certified) and the work is genuinely minor. Removing 1,200 ft² of floor tile is not a small-scale, short-duration activity in the regulatory sense unless it truly qualifies - and intact tile that is pried up without sanding or grinding may be handled as non-friable, but the moment it is broken, ground, or sanded it becomes regulated.
Even for non-friable removal, the LEA must: (1) use trained/accredited personnel; (2) follow the management plan's response-action provisions (763.93); (3) comply with NESHAP notification if the material is regulated (RACM) or if the removal method will render it friable; (4) comply with OSHA 29 CFR 1926.1101 for its own employees, including exposure monitoring, respiratory protection, and medical surveillance where applicable; and (5) dispose of the material properly. Doing it 'to save money' without those steps is a compliance and liability exposure. The inspector should recommend the LEA either use a certified contractor or document that its staff are accredited and the work meets all the above.
