Hazards and Cleanup

Contractors, business owners and landlords must identify and properly abate asbestos-containing materials before renovation or demolition of any building.

Licensing and certification for asbestos abatement requires training, documentation of previous asbestos abatement experience, and registration with the Construction Contractors Board and the Oregon Business Registry.
DEQ's asbestos program is moving to a new electronic data management system called Your DEQ Online


Starting on Aug. 10, 2021, you can set up your account and start submitting notifications and fees electronically. As of that date, all notification and application forms will be on Your DEQ Online and will not be available in PDF or Word format. The date is TBD​

DEQ is very excited to roll out this new, electronic service to asbestos abatement contractors and training providers! If you have questions, please contact the asbestos specialist in your area.


Frequently asked questions

In fall 2018, Oregon adopted additional requirements for handling asbestos-containing material. Read about some of the changes on Oregon’s updated asbestos rules here. You can also review Chapter 340 Division 248  "Asbestos Requirements" for a complete review of the requirements.
All commercial buildings regardless of construction date and residential buildings constructed before 2004 must have an asbestos survey conducted by an accredited inspector prior to any demolition or renovation activities, with one main exception. Owner-occupants of a single family home doing their own home renovation work are exempt from this rule. A copy of the asbestos survey report must be on-site during all renovation or demolition activities, and must be provided to DEQ upon request. Read more about asbestos survey requirements.
Required notifications include:
As of November 2018, distinct layers cannot be composited for analysis. When a sample consists of two or more distinct layers or materials, each layer must be treated separately and the results must be reported by individual layer.
Plaster and stucco: If plaster and stucco wall or ceiling systems are layered, and the layers can be distinguished, then the layers must be analyzed separately. Where a plaster or stucco wall system is constructed in layers, and the asbestos-containing layer becomes a distinguishable but "non-separable" component of the wall system, the results of the analysis of the individual layer(s) may include a small amount of the other layers when analyzed (for example: a skim or brown coat layer may contain a small amount of the base coat layer in the analysis of the skim coat layer).
Add-on materials (surfacing): All materials "added" to wallboard or other base materials (such as sprayed-on materials, paint, ceiling or wall texture) must be analyzed separately, if possible. The results of the analysis of those individual layers of "add-on" material cannot be averaged with the result of the analysis of wallboard for a composite result, but must be analyzed and reported separately. Where a thin coating of one material is applied over another material and the materials cannot be separated without compromising the layers, the analysis may include a small amount of the base layer. If for example, a paint layer containing asbestos is spread over a wallboard layer, and the paint layer cannot be separated from the wallboard, then a small amount of the wallboard layer may be included in the sample of the paint.
Joint compound and wallboard: When joint compound and/or tape is applied to wallboard it becomes an integral part of the wallboard and in effect becomes one material forming a wall or ceiling system. Therefore, a bulk sample of the system that contains the joint compound, tape, and wallboard may be analyzed to identify the asbestos percentage of the system. Surfacing materials or other layers that can be separated must not be included in the analysis.
Oregon DEQ and OSHA produced an asbestos guide to help construction workers and employers understand the rules and regulations surrounding the dangerous task of working with materials containing asbestos.
Asbestos is commonly found in walls, ceilings, floors, roofs, siding, HVAC systems, insulation, pipes and more.
To obtain a license from DEQ, contractors must submit a complete asbestos abatement contractor license application and a non-refundable $1,000 fee. Applicants must provide the following information
  1. Registration with the Oregon Construction Contractors Board.
  2. Registration with the Oregon Business Registry Section of the Corporations Division.
  3. A list of certified supervisors employed by the company.
  4. A list of all asbestos-related enforcement actions taken against the company.

​Any area where friable asbestos materials are to be abated must be enclosed with a negative pressure enclosure prior to and during abatement.

A negative pressure enclosure is not required when abating petroleum-based roofing products, cement asbestos roofing, or if the project can be contained in a single glove bag.

Barrier Requirements:
The barrier must cover all gaps in the area surrounding the asbestos abatement, including doorways, windows, HVAC systems, drains, plumbing, and other gaps with plastic with a minimum thickness of 6 mil.

Plastic sheeting that does not cover a gap in the abatement area, but is used to protect structural components or equipment, does not have to have a thickness of 6 mil.

Waste Handling and Disposal:
The material used to establish a negative pressure enclosure is considered Asbestos-Containing Waste Material (ACWM), and must be packaged and disposed of in accordance with DEQ regulations.

If you are conducting cleanup on a property affected by the 2020 wildfires, please visit DEQ's Wildfires web page for more information on cleanup and debris removal.

A variance was approved by the Environmental Quality Commission on Oct. 9, 2020, which temporarily suspends certain asbestos requirements for wildfire cleanup work. This variance has been extended until July 31, 2022. See DEQ's Wildfire Rule Suspensions page for more information.
