Frequently asked questions
The Oregon Department of Environmental Quality requires Metro to screen for, and prevent the acceptance of, asbestos in materials brought to Metro Central and Metro South transfer stations. To ensure the safety of our customers and the public, Metro requires paperwork for all loads of construction, remodeling or demolition waste for materials that may contain asbestos.
Analytical test results certifying all tested sample results contain 1 percent or less asbestos by weight are required for the following items:
- Flooring: vinyl tiles, vinyl sheet, cove base molding, mastic
- Walls: plaster, decorative plaster
- Siding: cement siding shingles (e.g., “Transite”)
- Ceilings: acoustical tiles, "popcorn” and spray-on texture
- Insulation: spray-applied, blown-in, vermiculite, pipe, HVAC and lagging
- Electrical: wire insulation, panel partitions
- Other: fire doors, fire brick, fire proofing
Starting April 1, 2017, Metro will require similar test results for asbestos for the following list of construction materials, in addition to those listed above:
- Drywall: includes separate analytical tests for texture, compound mud and gypsum
- Interior textures: spray-on, trowel-applied and skim/brown coats
- Insulation: block, boiler and spray-applied sink undercoating
- Gaskets: furnace, boiler and wood stove
- Roofing materials: tar paper, felt, Nicolite paper, silver/white roofing paint
- Various compounds: window glazing, cements, adhesives, caulks, patching and vapor barrier products
Metro reserves the right to request analytical test results for other materials not listed above.
Customers who bring these materials to Metro Central or Metro South transfer stations must certify that their loads of construction, remodeling and demolition debris are asbestos-free. To do this, complete a Construction and Demolition Waste Acceptance form.
Documentation must be presented to the bay spotter for review prior to opening the drop‐box or truck doors. The load will be inspected by the spotter to make sure it matches the description of materials on the Construction and Demolition Waste Acceptance form. Metro will retain a copy of the acceptance form and test results for its records. Customers who do not comply with the procedures may be charged testing and clean-up fees.
Information for residential DIY-remodelers
Loads of construction, remodeling and demolition debris brought to Metro transfer stations by residential DIY-remodelers will be thoroughly screened for materials that may contain asbestos.
DIYers: Starting a remodeling or home improvement project?
If you are a residential DIY remodeler, take these steps to prepare your load of construction waste for delivery to a Metro transfer station:
- Use an accredited asbestos inspector to survey your project for materials that may contain asbestos.
- Have any suspect materials tested by an analytical laboratory.
- Bring test results with your load to a Metro transfer station to show it contains 1 percent or less asbestos by weight.
Where to take waste that contains asbestos
Residential (non-commercial) customers may bring limited amounts of asbestos-containing materials to a Metro household hazardous waste facility. The materials must be delivered in no more than two sealed 25-pound double-lined six-millimeter plastic bags. The asbestos-containing materials must be bagged and sealed before they arrive at a Metro household hazardous waste facility. Metro accepts no more than two 25-pound bags per customer per day.
Commercial customers and residential customers with more than 50 pounds of asbestos-containing materials can take their load to Hillsboro Landfill. It is the only landfill near the Portland metropolitan area that can receive waste that contains asbestos for disposal. Loads must be properly and safely prepared before they are delivered to the landfill. Please call the landfill in advance of your delivery. For details, hours of operation and pricing, call Hillsboro Landfill at 503-640-9427.
Ask Metro about requirements, materials accepted and fees at Metro transfer stations. Find information about how to identify asbestos and protect yourself, your family and neighbors from it, and lists of accredited asbestos abatement contractors and analytical laboratories from the Oregon Department of Environmental Quality website or call 503-229-5982.
