Regulatory framework: NESHAP, OSHA, and Oklahoma DEQ rules

What this domain tests

NESHAP governs the building and the waste stream; OSHA governs the worker; Oklahoma DEQ licenses people and receives notifications. Questions ask which rule controls a given decision.

NESHAP (40 CFR 61 Subpart M)

  • Applies to owners and operators of facilities before renovation or demolition.
  • Regulated asbestos-containing material (RACM): friable ACM; Category I nonfriable that becomes friable or will be sanded, ground, or cut; Category II nonfriable that becomes friable or will be sanded, ground, or cut. Category I covers resilient floor covering, asphalt roofing, packings, and gaskets.
  • Thresholds: 260 linear feet on pipes, 160 square feet on other components, or 35 cubic feet where area and length cannot be measured.
  • Written notification at least 10 working days before work starts.
  • Removal must be wet, in whole pieces where possible, lowered rather than dropped, with no visible emissions.

OSHA (29 CFR 1926.1101)

  • PEL 0.1 f/cm³ as an 8-hour TWA; STEL 1.0 f/cm³; excursion limit 1.0 f/cm³.
  • Class I–IV work categories, a competent person, regulated areas, training, medical surveillance, and a negative exposure assessment before certain work.

Oklahoma

  • The DEQ Air Quality Division administers the Oklahoma Asbestos Control Act, licenses abatement contractors and individuals, and requires notification at least 10 working days before abatement begins.
  • Worker-safety enforcement runs through Oklahoma's OSHA-approved state plan, administered by the Oklahoma Department of Labor.

Worked example

A renovation will disturb 300 linear feet of pipe insulation and 200 square feet of ceiling tile. Because 300 exceeds 260 linear feet, the pipe insulation alone makes this a regulated renovation; notification is due 10 working days ahead, and the tile quantity does not change the trigger.

Traps

  • Applying the 160-square-foot threshold to pipe insulation.
  • Treating nonfriable material as automatically exempt.
  • Missing the 10-working-day notification clock.
