Regulatory Framework (Federal and Massachusetts)
This domain tests which agency regulates which part of an asbestos project and which notifications, licenses, and standards apply. Candidates must separate worker protection, air pollution, waste, and licensing requirements.
Federal roles
OSHA 29 CFR 1926.1101 governs worker protection: exposure limits, regulated areas, respiratory protection, training, medical surveillance, and work practices. EPA’s NESHAP, 40 CFR 61 Subpart M, governs asbestos emissions and requires notification and proper handling of regulated asbestos-containing material (RACM). AHERA, 40 CFR 763, imposes inspection, management, and clearance rules in schools.
Massachusetts roles
Massachusetts adds state requirements. The Department of Labor Standards (DLS) administers asbestos contractor, supervisor, and worker licensing/certification and work-practice rules under 454 CMR 28.00. MassDEP administers air-pollution notification and waste requirements, including 310 CMR 7.15 and solid-waste rules. Notification is generally due at least 10 working days before abatement begins, with limited emergency provisions.
Worked example
A project removes 300 linear feet of pipe insulation and 180 square feet of floor tile. NESHAP thresholds are 260 linear feet, 160 square feet, or 35 cubic feet. The pipe insulation alone exceeds the linear-foot threshold, so the project is regulated and requires notification. Floor tile is Category I nonfriable, but sanding or grinding can make it RACM. A licensed contractor and trained workers are required; notification must be timely and accurate.
Traps
Do not assume one agency covers everything. Do not count calendar days when the rule says working days. Do not use the emergency exception for a planned job. Do not overlook that nonfriable material can become regulated when cut, ground, or broken.
