Regulatory Framework and Compliance
Domain focus
This domain tests how OSHA, EPA NESHAP, AHERA, RCRA, and state rules fit together. Questions often ask who must notify, when, and which standard controls a task.
Core rules
- OSHA 29 CFR 1926.1101 protects workers: PEL 0.1 f/cc 8-hour TWA, STEL 1.0 f/cc for 30 minutes, excursion 1.0 f/cc over 30 minutes; regulated areas, exposure monitoring, competent person, and respiratory protection apply.
- NESHAP 40 CFR 61 Subpart M controls air emissions. The owner/operator must notify the EPA or state at least 10 working days before renovation or demolition when regulated asbestos-containing material will be disturbed above 260 linear feet on pipes, 160 square feet on other components, or 35 cubic feet off components.
- AHERA 40 CFR 763 covers K-12 school inspections, management plans, and accredited personnel.
- RCRA and state rules govern waste packaging, manifests, transport, and approved disposal.
Worked example
A renovation will disturb 300 linear feet of friable pipe insulation and 200 square feet of floor tile. Pipe insulation alone exceeds the 260-linear-foot threshold, and the tile exceeds 160 square feet if it is RACM. NESHAP notification is required at least 10 working days before work. OSHA still requires worker protection, and state notification may be separate.
Traps
Notification is not a permit and is not the same as OSHA exposure monitoring. Count working days, not calendar days. The owner/operator has the NESHAP duty. Do not assume floor tile is exempt: grinding or sanding can make it regulated.
