Oregon DEQ Asbestos Abatement
This domain covers Oregon DEQ's asbestos abatement program: how Oregon identifies regulated asbestos-containing material (ACM), who may remove it, when DEQ must be notified, and how work and waste must be controlled. Exam items in this domain test application of those rules to project scenarios, not just definitions.
Core rules
- ACM is material containing more than 1% asbestos by weight. Oregon regulates abatement of ACM; nonfriable ACM can become regulated when cutting, grinding, or demolition makes it friable.
- Before renovation or demolition, an accredited inspector must survey the structure and document the location, quantity, and condition of suspect materials. A contractor's bid is not a survey.
- Abatement contractors must be licensed by Oregon DEQ; supervisors and workers must be certified. Licensing and certification are tied to the contractor and to the individual.
- The contractor must notify DEQ at least 10 working days before abatement begins. Notification is not permission to skip the survey, licensing, or work-practice rules.
- Work practices control emissions: wet methods, HEPA vacuuming, negative-pressure enclosures where required, decontamination, air monitoring, and clearance before reoccupancy.
- Asbestos waste must be wetted, sealed in leak-tight labeled containers, and disposed of at a landfill permitted to accept asbestos; keep disposal records.
Worked example
A crew plans to remove 200 square feet of floor tile and mastic containing 2% asbestos from a commercial building in three days. Is this regulated abatement? Yes: the material exceeds 1%, and removal disturbs it. The contractor needs a DEQ license, certified workers and supervisor, a prior survey, and a notification received by DEQ 10 working days before start. Three days is too short; the job is not an emergency unless it meets DEQ's emergency criteria. Starting anyway is a violation even if the tile is “nonfriable,” because cutting and scraping can create friable debris.
Traps
Treating “less than 1%” as automatically exempt without sampling; confusing notification with approval; counting calendar days instead of working days; assuming nonfriable means no controls; and forgetting waste manifests.
